Release date: 2018-05-07 Source: OFweek Semiconductor Lighting Sharing: The liquid crystal display device now uses a blue LED, which is combined with a yellow phosphor, a light guide plate and a dispersing sheet, and then constitutes a backlight system for the liquid crystal display. This kind of system, although cost-effective, but the color is not good, because the blue LED system is naturally short of red and green expression. In the past, high-end liquid crystal display devices used RGB LED backlights. This backlight system certainly works well, but the cost of helplessness is too high, and the space for demand is large. The RGB LED backlights have not been widely used. Now with the continuous development of LED technology, the future high-end LCD display may use Mini LED. This backlight system can add the number of dimming partitions to improve the color and contrast of the LCD panel. The LED usage is as high as 6000 to 7000. However, with the addition of LED usage, manufacturers still need to overcome the heat dissipation problem that comes with it. In addition, in order to adjust the amount of LEDs for more partitions, the amount of LEDs will increase simultaneously, and the function will be improved. Together, the cost has also risen sharply, which means that the price of the product with the Mini LED must be more than $1,000, and it can take on the high cost structure of the Mini LED. The price of such a product in China is about 10,000 yuan. In fact, there is now a quantum dot backlight for improving the color appearance of the liquid crystal panel. Future Mini LED backlights and quantum dot backlights will become the primary components of the high-end display backlight system. Although the traditional blue LED backlight is low in cost, the color display cannot meet the new needs of users.
