Technological Transformation Brought By Mini LED And Its Supply Chain

- Aug 28, 2020-

With the development of display technology, the panel industry will no longer only focus on the supply and demand. Instead, more emphasis has been placed on the quality and specs upgrade of panels in order to increase the value of display products. This trend has motivated the display panel makers towards better specs, such as high resolution, curved, ultra-thin, lightweight, bendable, high dynamic HDR, high contrast, and wide color gamut. In this way, the displays will be able to present more natural colors and vivid image.

Mini LED will have a wider application range

Current display products use mostly a backlight structure, but the next-generation display technology will be self-emitting, which has a simpler structure than the backlight. Therefore, self- emitting displays are more suitable to make thinner and bendable products. Mini LED can replace the backlight module in nowadays LCD displays. With the features of power saving, thinness, and higher luminous efficiency, Mini LED will be competing with OLED products. Mini LED has improved uniformity in light emission due to miniaturization of light sources, resulting in wider application of Mini LED. For example, it can be applied to outdoor displays, automotive head-up displays, automotive displays, head-mounted displays, wearable devices, mobile phones, televisions, gaming laptops, Pico projectors, etc.

Mini LED technology will compete with OLED technology

With sizes of about 100-200μm, Mini LED chips can made into lightweight products through Chip Scale Package (CSP) technology. Mini LED technology will enable features like high resolution, low power, and high brightness, so the pixel pitch will be reduced and the number of LED chips will be largely increased. In addition, light sources using Mini LED technology will have lighter and thinner structure in the product design, and can also provide better contrast and better wide color gamut under local-dimming condition.
