Thanks to the offensive attitude of domestic screen manufacturers for Mini LED market, in the next five years, Mini LED Backlight Unit (BLU) technology will gradually become the mainstream technology for mid- to high-end displays, and its technology will continue to improve, the number of LEDs is improved, the technology of zoning control is also constantly improved. In the future, Mini LED is likely to take the lead in applications that have advantages over LCD or OLED, mainly for TV, wearable devices, automotive and other application scenarios, as well as for flexible and transparent light displays applications.
For Mini-LED, by using dotting type of silicone in the LED, a TV needs more than 10,000 LEDs. While the LSR silicone lens can decrease the number of LEDs by increasing the pitch between LEDs, so to lower the production costs.
Take 65-inch display as an example:
By silicone dotting type, the pitch value per 10*10, the lens diameter is 0.8mm, it needs 14,440 LEDs.
By using Liquid injection molding silicone lens, the pitch value can be increased to 20*25, the lens diameter is 4.2mm, the number of lenses needed has been reduce to 4800pcs.
The principle of Mini LED is to change the original LED backlight board into thousands of individual LEDs, where multiple LEDs form a LED backlight matrix, each backlight matrix can be turned into a separate light control zone. Taking one of the top Mini LED gaming screens on the market as an example, it has 4096 LEDs, every two can be composed of a light control zone, that is, with 2048 separate light control zone.
The advantage of this is that Mini LEDs also have the same ultra-high contrast ratio as OLEDs and a more refined, adjustable local brightness, because when the black area is displayed, the LEDs in the area are in the off state, so its contrast ratio is theoretically equal to that of OLED displays, while there is no risk of burning the screen with OLED displays for a long time. A major advantage of Mini LED is that its independent area LEDs can excite a large brightness in a short period of time, in some excellent Mini LED can achieve the highest brightness of 2000 nits in the local area, common Mini LED can also basically pass the HDR1000 certification, which makes Mini LED for HDR content is very friendly, Mini LEDs are comparable to OLEDs for HDR content display.
With the market demand for Mini LED and the end users' sensitivity to price, the demand for LSR injection molding lenses will gradually expand.
