WHAT IS A MICROLED DISPLAY AND HOW DOES IT WORK?
The are two technologies at the heart of most modern televisions and monitors, liquid crystal displays (LCD) and light emitting diode (LED) displays.
An LED screen uses light-emitting diodes as a source of light behind the screen, as opposed to LCDs which use cold-cathode fluorescent lamps.
Organic (OLED) sets emit light using a layer of material based on carbon, which in a technical sense makes them organic.
Sets using OLEDs, primarily made by LG, tend to be pricey because they are difficult to produce.
Manufacturers say MicroLEDs are brighter than OLEDs and offer the same benefits of high contrast and deep blacks, without burn-in. Samsung's gigantic new 146 inch The Wall TV (pictured) is the first to use the technology
Pixels, the individual points that form an image, are self-illuminating in OLEDs and can be shut off individually.
That means images can have truly black areas, rather than just very dark.
OLED sets also cut down on light spillage in scenes where bright and dark colours are side by side, which means you see sharper contrast.
OLED sets also have a wider viewing angle than regular sets, but they aren't as bright as other displays and can suffer 'burn-in' if a static image is left on screen for too long.
Just as with OLEDs, sets with MicroLED technology have self-illuminating pixels but the material used is slightly different and isn't organic.
Manufacturers say MicroLEDs are brighter than OLEDs and offer the same benefits of high contrast and deep blacks, without burn-in.
Samsung is unveiling a 146-inch MicroLED set this year.
