The first embodiment of the present application provides a wearable device based on a Micro-LED dynamic adaptive texture. Please refer to Figure 1, which is a schematic diagram of the first embodiment of the present application. The following is a detailed description of a wearable device based on a Micro-LED dynamic adaptive texture provided by the first embodiment of the present application in conjunction with Figure 1.

The Micro-LED-based light therapy wearable device includes a Micro-LED display module 101, a physiological monitoring sensor 102, a control unit 103, a data storage unit 104, a power management unit 105 and a user interface 106.

The Micro-LED display module 101 is used to emit designated light according to the instruction of the control unit to provide a personalized light therapy plan.

In this embodiment, the Micro-LED display module 101 is a light source component based on Micro-LED technology, which is used to emit specified light in a light therapy wearable device to provide a personalized light therapy solution. The module is composed of a plurality of tiny LEDs, each of which is capable of producing light of a specific color. By precisely controlling the brightness and color output of each Micro-LED, the display module is able to generate a wide range of colors and light intensities to meet different light therapy needs.

The Micro-LED display module 101 is composed of tens of thousands of microscopic light-emitting diodes (LEDs) that are precisely arranged on a small chip. Each LED unit can be independently controlled, allowing the module to produce a variety of colors and light patterns. These LED units are capable of emitting red, green, and blue light, respectively, and through the combination of different color lights, a variety of spectra can be created, ranging from warm sunlight to cool blue light. In addition, the module can adjust the light intensity from soft lighting to strong lighting to suit different treatment and environmental needs.

The control unit 103 is electrically connected to the Micro-LED display module 101 and is responsible for issuing light emission instructions to the display module according to a preset light therapy program. These instructions include specified color combinations, light intensity, and flashing frequency to achieve the desired light therapy effect. The control unit is also capable of receiving real-time physiological data from the physiological monitoring sensor 102, such as heart rate, blood pressure, and skin electrical activity, and dynamically adjusting the output of the display module based on these data to ensure that the light therapy program responds to changes in the user's physiological state in real time.

In order for the Micro-LED display module 101 to work properly in the light therapy wearable device, it also needs to be connected to the power management unit 105, which is responsible for providing a stable power supply to the display module and other device components. The power management unit optimizes energy consumption and ensures that the device can operate for a long time without frequent charging.

The user interacts with the display module through the user interface 106, which allows the user to select or customize the light therapy program. The user's selection or customized settings will be stored in the data storage unit 104, and the control unit will instruct the display module to output the light therapy program selected by the user.

Furthermore, the Micro-LED display module includes an adaptive brightness adjustment submodule for automatically adjusting the brightness of the display module according to the user's retinal response.

In this embodiment, the Micro-LED display module is equipped with an adaptive brightness adjustment submodule. The core function of this submodule is to automatically adjust the brightness of the display module according to the user's retinal response, thereby optimizing the light therapy process and improving the user experience.

The main task of the adaptive brightness adjustment submodule is to monitor the user's retinal response in real time and automatically adjust the brightness of the light emitted by the Micro-LED display module accordingly. This monitoring can be achieved through a retinal response sensor integrated in the light therapy wearable device, such as a small camera or photoelectric sensor, which can capture changes in the user's eyes, such as changes in pupil size, which generally reflects the eye's physiological response to light brightness.

Implementation methods include:

1. Retinal response sensor: First, you need to choose a suitable sensor to capture the user's retinal response. This may include a highly sensitive camera or a specially designed photoelectric sensor that can accurately measure the pupil's response to different brightness levels.

2. Data processing and analysis: The data collected by the sensor needs to be processed and analyzed by the algorithm in the control unit. This algorithm can interpret the pupil response data, such as the degree of pupil dilation or contraction, and judge whether the current brightness level is suitable for the user.

3. Brightness adjustment: Based on the analysis of retinal response, the adaptive brightness adjustment submodule sends instructions through the control unit to automatically increase or decrease the brightness of the Micro-LED display module. This adjustment process aims to find an optimal brightness level that makes the user feel comfortable while ensuring the maximum light therapy effect.

By adaptively adjusting the brightness of the display module to match the user's retinal response, the user's light therapy experience can be significantly improved. This not only prevents visual discomfort caused by excessive brightness, but also avoids the light therapy effect being affected by low brightness. In addition, this adaptive brightness adjustment technology can also provide users with a more personalized treatment plan because it is optimized based on the user's specific physiological response.

In summary, by integrating the adaptive brightness adjustment submodule into the light therapy wearable device, the personalization and comfort of light therapy can be significantly enhanced, providing users with a safer and more effective light therapy solution. The detailed description of this innovative feature ensures the feasibility of the technology and meets the requirements of the patent law for the specification.

In summary, the Micro-LED display module 101 is a core component of the light therapy wearable device, which uses micro-LED technology to provide a personalized, dynamically adjusted light therapy solution. By working in conjunction with other components in the device, the display module is able to provide a customized light therapy experience based on the user's real-time physiological data and personal preferences.

The physiological monitoring sensor 102 is used to collect the user's physiological data in real time, including heart rate, blood pressure and skin electrical activity.

The physiological monitoring sensor 102 plays a crucial role in the light therapy wearable device provided in this embodiment. It is responsible for collecting the wearer's heart rate, blood pressure, skin electrical activity and other physiological data in real time. These data not only provide the wearer's current physiological state information, but also serve as the basis for adjusting the personalized light therapy plan. The physiological monitoring sensor 102 will be described in detail below.

The physiological monitoring sensor 102 is a module composed of multiple sensors with different functions, each of which is optimized for specific physiological signals. The heart rate sensor uses photoplethysmography (PPG) technology to measure blood flow velocity by emitting and receiving light reflected by the skin, and then calculate the heart rate. Blood pressure monitoring usually uses non-invasive blood pressure measurement technology to estimate blood pressure levels by analyzing changes in heart rate signals. The skin electrical activity sensor is based on changes in conductivity, and evaluates the user's emotional state and stress level by monitoring tiny changes in current on the skin surface.

The sensors are integrated into a compact module designed to ensure they can work stably while the wearer performs daily activities and are non-irritating to the wearer's skin. The placement and wearing method of the sensors are also carefully designed to ensure that data can be collected effectively without affecting the wearer's comfort and freedom of movement.

In order to realize real-time monitoring and transmission of data, the physiological monitoring sensor 102 also includes necessary electronic circuits and communication modules. The electronic circuit is responsible for preliminary processing of the raw data collected by the sensor, such as amplifying the signal, filtering noise and digital conversion. The communication module is responsible for transmitting the processed data to the control unit 103 in real time for further analysis and processing.

The design of the physiological monitoring sensor 102 takes full account of energy consumption to ensure the battery life of the entire light therapy wearable device.

In summary, the physiological monitoring sensor 102 provides an efficient, accurate and user-friendly way for the light therapy wearable device to collect and monitor the wearer's physiological data through precise design and integration. The collection and analysis of this data is the key to realizing a personalized light therapy program, which enables the device to adjust the light therapy program according to the wearer's real-time physiological state to achieve the best treatment effect.

The control unit 103 is electrically connected to the Micro-LED display module, the data storage unit and the physiological monitoring sensor, and is used to issue a light emission instruction to the Micro-LED display module according to a preset light therapy plan stored in the data storage unit; receive and process physiological data from the physiological monitoring sensor, and dynamically adjust the light output characteristics of the Micro-LED display module based on the physiological data; wherein the light output characteristics include light intensity, generated color, and flickering frequency.

The control unit 103 is the brain of the Micro-LED-based light therapy wearable device, responsible for command processing, data management, and communication coordination of the entire system. This unit integrates advanced software algorithms with hardware to ensure that the device provides personalized light therapy solutions based on the user's real-time physiological responses and preset preferences. Its design and functional implementation ensure the intelligent operation and user-friendliness of the device, enabling the device to provide light therapy services while minimizing energy consumption and extending battery life.

The control unit 103 has a built-in microprocessor or microcontroller, which is responsible for executing software programs, including issuing light emission instructions to the Micro-LED display module according to the preset light therapy program stored in the data storage unit 104, wherein the preset light therapy program includes the intensity, color and flickering frequency of light within a preset period of time; receiving data from the physiological monitoring sensor 102, processing the data to determine the current physiological state of the user, and dynamically adjusting the light output characteristics of the Micro-LED display module 101 according to this state. These characteristics include but are not limited to the intensity, color and flickering frequency of light, which can be finely adjusted according to the physiological data of the user.

The control unit 103 is also designed with communication interfaces, which enable the unit to be electrically connected to other parts of the device, including the Micro-LED display module 101, the physiological monitoring sensor 102, the data storage unit 104, and the power management unit 105.

In order to achieve efficient power management, the control unit also monitors and adjusts the energy consumption of the device. This is achieved by optimizing the power usage of the Micro-LED display module 101 and the physiological monitoring sensor 102, and intelligently adjusting the power consumption according to the current working state of the device, thereby extending the use time of the device after a single charge.

The software programming of the control unit is very critical. It contains algorithms to interpret the data collected by the physiological monitoring sensors and adjust the light therapy plan based on this data. This requires the software inside the control unit to handle complex logical judgments to achieve the best match between the light therapy effect and the user's needs.

Furthermore, the control unit includes an algorithm module for processing physiological data from the physiological monitoring sensor, and the algorithm module uses the following formula 1-5 to calculate the light output characteristics of the Micro-LED display module:

, and : The reference values for each color component refer to the default color output settings of the device before specific physiological feedback adjustments, that is, the color output settings in the preset treatment plan. These reference values determine the initial light color at the beginning of light therapy, providing a starting point for light therapy, and subsequent adjustments will be based on this reference value.

and : Current and baseline heart rate variability.

Heart rate variability (HRV) refers to the variation in the time intervals between heart rate (heartbeats), and is an important indicator of the heart's response to changes in the internal and external environment. HRV can reflect the activity and balance of the autonomic nervous system, among which a higher HRV is generally considered to be a sign of good health for the heart and the entire body.

Baseline HRV refers to the value of heart rate variability measured under specific, controlled conditions, usually in a quiet, relaxed state. This value serves as a reference point for the HRV level of an individual when not affected by specific external stimuli or internal physiological changes, and can be used to compare with subsequent HRV values measured under different conditions to assess the response of the heart and autonomic nervous system to various stimuli.

and : Current and baseline galvanic skin responses.

Galvanic Skin Response (GSR), also known as electrical skin response, refers to changes in the electrical conductivity of the skin surface, which is mainly caused by increased activity of sweat glands under the skin and is related to emotional state, psychological stress or physiological activation level. GSR is one of the non-invasive methods to measure the activity of the autonomic nervous system, especially the response related to emotions and psychological stress.

Baseline HRV refers to the value of heart rate variability measured under specific, controlled conditions, usually in a quiet, relaxed state. This value serves as a reference point for the HRV level of an individual when not affected by specific external stimuli or internal physiological changes, and can be used to compare with subsequent HRV values measured under different conditions to assess the response of the heart and autonomic nervous system to various stimuli.

The introduction of the color adjustment formula enables light therapy wearable devices to adjust color output according to the user's mood and stress level (reflected by HRV and GSR), increasing the mood regulation function of light therapy and making users feel more comfortable and relaxed when receiving light therapy.

Flicker frequency adjustment formula (Formula 5):

;

: Calculated flashing frequency.

: Reference flicker frequency, representing the flicker rate under standard or initial conditions.

and : Adjustment coefficient, obtained through experiments or statistical analysis, used to adjust the impact of heart rate and GSR changes on the flicker frequency.

Adjustment of the flash rate is based on changes in heart rate and GSR, further enhancing the personalization and adaptability of light therapy. Adjustment of the flash rate is particularly important for certain specific light therapy effects, such as promoting relaxation or concentration.

These formulas are based on a comprehensive analysis of physiological, psychological and phototherapy research. By analyzing the relationship between the user's physiological data (HR, HRV, BP, GSR) and the effect of phototherapy, researchers are able to determine which parameter changes most affect the effect of phototherapy, and design formulas to dynamically adjust the phototherapy conditions accordingly. The benefit of this approach is that it allows phototherapy devices to more accurately match the user's real-time needs, providing more effective and personalized treatment plans, thereby improving the user's overall satisfaction and phototherapy effect.

Furthermore, the control unit includes an emotion analysis module for analyzing the user's emotional state based on the physiological data collected from the physiological monitoring sensor, and adjusting the color combination of the light output characteristics based on the analysis result to promote the improvement of the user's emotion.

In the Micro-LED-based light therapy wearable device provided in this embodiment, an emotion analysis module is added. The introduction of this module adds a new function to the device: it can analyze the user's emotional state based on the user's physiological data and adjust the color combination of the light output characteristics accordingly to promote the improvement of the user's mood. The realization of this function not only enhances the personalized experience of the light therapy device, but also provides users with a new means of emotion regulation.

The emotion analysis module is part of the control unit, which analyzes the user's emotional state using data collected from physiological monitoring sensors, such as heart rate, blood pressure, heart rate variability (HRV), galvanic skin response (GSR), etc. These physiological indicators can reflect the user's autonomic nervous system activity, thus providing important clues about the user's emotional state.

The emotion analysis module processes these physiological data by applying specific algorithms to identify the user's possible emotional state, such as calm, nervous, happy or sad, etc. This process involves complex data analysis and pattern recognition technologies, such as machine learning or deep learning methods, which can learn and identify specific emotion-related physiological patterns in large amounts of data.

Once the user's emotional state is identified, the emotion analysis module will guide the control unit to adjust the light output characteristics of the Micro-LED display module, especially the color combination. Different colors have different effects on people's emotions. For example, blue is generally considered to have a calming effect, while yellow may promote happiness. Therefore, based on the user's current emotional state, the system will select the color combination that is most suitable to promote improved emotions.

In summary, the control unit 103 provides the user with a highly personalized and responsive light therapy experience through its advanced processing capabilities and software and hardware integration.

This data flow ensures the personalization and adaptability of the light therapy plan, so that the light therapy effect can better meet the actual needs of the user.

In addition, the design of the data storage unit 104 also takes into account the organization and management of data. It may include multiple partitions or directories for logical separation of different types of data, such as storing historical physiological data and preset light therapy plans separately.

The user can view his or her physiological data, historical trends, and feedback on the effect of light therapy through this application. In addition, the wireless communication module can also receive data from external devices, such as the light therapy plan or preference settings set by the user through the application, and then transmit this information to the control unit to adjust the working mode of the light therapy device.

The design and implementation of this wireless communication module should take into account the energy consumption management of the device to ensure that the communication process does not have a negative impact on the device's battery life. At the same time, the design of the module should also take into account ease of use and compatibility to ensure that it can be smoothly connected and communicated with various external devices.

In summary, the addition of wireless communication modules has greatly enhanced the functionality of wearable light therapy devices, enabling the devices to not only provide personalized light therapy plans, but also monitor the user's physiological responses in real time and share this information seamlessly with users and medical service providers, bringing users a more comprehensive health management experience.

Furthermore, the light therapy wearable device also includes an ambient light sensor for detecting the ambient light conditions of the surrounding environment of the Micro-LED display module; the control unit adjusts the light output of the Micro-LED display module based on the detected ambient light conditions to ensure that the effectiveness of the light therapy scheme is not affected by external light.

The Micro-LED-based light therapy wearable device provided in this embodiment has an added ambient light sensor function, which is an important improvement that allows the device to sense and adapt to the light conditions around it. The addition of this function ensures that the light therapy program can maintain its expected effect regardless of how the external ambient light changes, enhancing the flexibility of the device and the consistency of the effect.

An ambient light sensor is a component that detects the intensity of ambient light. It evaluates current lighting conditions by measuring the brightness of ambient light. This sensor usually contains a photosensitive element, such as a photodiode or photoresistor, which converts the amount of captured light into an electrical signal that changes with the intensity of ambient light.

The control unit receives the signal from the ambient light sensor and interprets it to determine the light intensity of the surrounding environment. Based on this information, the control unit adjusts the light output of the Micro-LED display module, including the light intensity, to ensure that the light therapy program can be effectively implemented in bright or dim environments, and the user experience will not be disturbed by changes in ambient light.

To achieve this function, the control unit will have a built-in algorithm that dynamically adjusts the settings of the Micro-LED display module based on the real-time data provided by the ambient light sensor. For example, if the ambient light sensor detects that the external environment is very bright, the control unit may increase the brightness of the Micro-LED display module to maintain the light therapy effect; on the contrary, if the external environment is detected to be dark, the control unit may reduce the brightness of the display module to avoid excessive light causing discomfort to the user.

By combining ambient light sensors with Micro-LED display modules, light therapy wearable devices can provide more intelligent and environmentally responsive light therapy solutions, ensuring that light therapy solutions maintain their effectiveness under various lighting conditions, thereby optimizing the user's light therapy experience.

Furthermore, the light therapy wearable device is a wristband, a neck ring or a headband.

In the aforementioned Micro-LED-based light therapy wearable device, the device is specifically implemented in the form of a bracelet, neck ring or headband, which provides the device with a variety of wearing methods to adapt to the preferences and light therapy needs of different users. The following is a detailed description of the light therapy device in the form of a bracelet, neck ring or headband, covering design considerations, functional implementation and how it interacts with the user.

First of all, whether it is a wristband, neckband or headband, these wearable devices need to be equipped with Micro-LED display modules, physiological monitoring sensors, control units, data storage units, power management units and user interfaces. The integration of these core components needs to take into account wearing comfort, device stability and maximization of light therapy effects.

For the bracelet form, the design needs to ensure that it is light and easy to wear. The Micro-LED display module can be integrated on the surface of the bracelet to directly perform light therapy on the skin. The physiological monitoring sensor is close to the user's skin to accurately collect data such as heart rate. The control unit and power management unit need to be cleverly laid out to minimize size and weight.

The design of the neck ring should take into account the comfort and safety when worn on the neck, especially when used for a long time, it should not cause discomfort or pressure to the user. The Micro-LED module in the neck ring can provide light therapy for the skin around the neck, suitable for users who need relaxation and treatment for the neck or shoulders.

The headband is particularly suitable for situations where light therapy is needed on the head, forehead or temples. The layout of the Micro-LED display module in the headband should ensure that the light can cover the area that needs treatment. At the same time, the design of the headband needs to take into account stability and comfort to avoid slipping or causing pressure when moving.

All of these wearable devices should be designed with user-friendly elements in mind. For example, user interfaces (such as touch screens or buttons) should be located in places that are easily accessible to users. In addition, power management units should ensure that the device has sufficient battery life to support long-term light therapy needs.

In terms of material selection, the bracelet, neck ring and headband should all be made of skin-friendly, lightweight and durable materials to ensure the user's comfort when wearing it for a long time. At the same time, the design of the device must also allow a certain degree of adjustment to adapt to the body shape and wearing preferences of different users.

Furthermore, the phototherapy wearable device also includes an audio output module, which is electrically connected to the control unit and plays music or sound synchronized with a preset phototherapy plan according to the instructions of the control unit to enhance the effect of the phototherapy.

The Micro-LED-based light therapy wearable device provided in this embodiment further adds an audio output module, which is an extension of the original device. The design of the audio output module is intended to enhance the effect of light therapy by synchronously playing music or sound, providing users with a more comprehensive treatment experience. The following is a detailed description of the functions of the audio output module.

The audio output module is a device capable of playing music or other sounds and is electrically connected to the control unit. This connection allows the audio module to receive instructions from the control unit and play specific audio files based on those instructions. The audio files can be pre-set or user-selected through the user interface to coordinate the execution of the light therapy regimen.

The control unit includes an algorithm module that processes data from the physiological monitoring sensors and adjusts the audio output based on this data and the preset light therapy program. For example, if the light therapy program is designed to help the user relax, the algorithm module will instruct the audio output module to play soft music or natural sounds, such as running water or rain. The algorithm can also dynamically adjust the rhythm or volume of the music based on the user's physiological responses (such as heart rate and skin galvanic response) to optimize the light therapy effect.

To achieve this function, the audio output module needs to have certain technical characteristics, including storage of audio files, audio playback capabilities, and a communication interface with the control unit. The module should support multiple audio formats so that it can play various types of music and sounds. In addition, the module should also have certain sound quality processing capabilities to ensure that the quality of audio playback meets the treatment needs.

The audio output module plays music or sounds in sync with the light therapy program, providing users with a multi-sensory treatment experience that not only stimulates the eyes but also the ears to relax or motivate. This multi-sensory treatment can enhance the effects of light therapy, improve user satisfaction and the effectiveness of treatment.

Furthermore, the wearable phototherapy device also includes a temperature control module for adjusting the surface temperature of the wearable phototherapy device according to instructions of the control unit.

The Micro-LED-based light therapy wearable device provided in this embodiment introduces a new feature, a temperature control module, which further enhances the functionality and user experience of the device. The purpose of this module is to enable the device to automatically adjust its surface temperature according to the instructions of the control unit, thereby providing users with a more comfortable and personalized light therapy experience.

The temperature control module allows the light therapy wearable device to automatically adjust the temperature of the device surface when performing light therapy. This temperature regulation capability not only prevents the device from overheating during long-term use, but also allows it to be adjusted to a more comfortable temperature based on the needs of the light therapy program or the user's personal preferences. For example, in the winter, the user may prefer a warm touch, while in the summer, they may prefer a cool surface temperature.

The temperature control module is mainly composed of a temperature sensor, a heating element (such as a heating plate or a heating coil) and/or a cooling element (such as a Peltier element), and a control circuit connected to a control unit. The temperature sensor is responsible for real-time monitoring of the temperature of the device surface and feeding back the temperature data to the control unit; the control unit adjusts the working state of the heating or cooling element through the control circuit according to the preset light therapy plan or the temperature preference set by the user to achieve the desired surface temperature.

The control unit has an embedded algorithm for handling temperature regulation, which dynamically adjusts the output power of the heating or cooling element based on the real-time temperature data received from the temperature sensor, as well as the requirements of the light therapy regimen or the user's temperature preference. The algorithm needs to accurately calculate the required temperature adjustment amount to ensure fast and accurate adjustment of the device surface temperature.

By integrating a temperature control module into a phototherapy wearable device, users can enjoy a more personalized and comfortable phototherapy experience. Proper temperature regulation can not only increase the user's comfort, but also help improve the effect of phototherapy, especially in treatment plans that require temperature effects to enhance the effect of phototherapy.
