Five, direct type ultra-thin technology

At this stage, large-size direct-lit LED backlights are developing into large-size edge-lit LED backlights.

Following the display requirements of low carbon, green, environmental protection, ultra-thin, and high color, the dynamic area of ​​edge-lit LED backlights in the later stage Controlling the backlight cannot reach the optimum value, and it needs to be thinner in the direct-lit backlight technology. By processing the microstructure of LGP and printing on the light guide plate, the LED lamp can meet the light mixing requirements in the shortest distance, and improve the transmission efficiency of the light source in the LGP, changing the original side-entry type due to long-distance transmission. problem of light loss.

While the large-size direct-lit backlight source is ultra-thin, the localdimming technology is completed to meet the requirements of low power consumption, and RGBLED or high-power white LED (RGB phosphor) is used on the basis of the direct-lit technology to achieve ultra-thin, low power consumption. High-consumption, high-color backlight products.
