When volume production of micro LED can kick off remains unclear, but mini LED used as backlight source of LCD display has already entered mass production in the second half of 2018 thanks to its lower cost and easier application involved, according to Digitimes Research.
Besides serving as backlight for LCD display, mini LED can also be applied to support active matrix light emitting display. But backlight application is easier to do and only single-color mini LED is needed in the application, involving simpler production process and lower production cost. Accordingly, mini LED can facilitate the incorporation of mass transfer technology, and its lower prices are more acceptable to consumers, Digitimes Research noted.
The application of mini LED as backlight of LCD display boasts high contrast ratio, power conservation and thinning advantages, able to compete with OLED and show distinct performances in LCD display applications. For instance, mini LED can be applied to gaming devices to highlight the scene ambiance and visual feeling at gaming devices, weather-resistance and visibility under strong light at in-vehicle displays, and resolution at TV sets.
