What is backlight
2021-06-17
The backlight is a light source device used to ensure the light is emitted behind the LCD screen.Because the liquid crystal display device itself is transparent and does not emit light, it needs a backlight to assist. Some indicators, such as the brightness and uniformity of the backlight, have a direct impact on the relevant performance of the liquid crystal display. Compared with CCFL, the color...

About LCD TV backlight
2021-05-31
As is well known, the liquid crystal panel itself cannot emit light, and a backlight is required as a light source. The LCD is like a small window that controls the opening and closing of light, and then turns the light into red, green and blue through the filter color to form a TV screen. In the early days, there was a three-primary RGB backlight, but the cost was high, and it has now disappeared...

What does LED backlight mean
2021-05-28
The LCD is a non-luminous display device, which requires the use of LED backlight source to achieve the display function. The performance of the LED backlight source will directly affect the display quality of the LCD. The cost of the backlight source accounts for 3-5% of the LCD module, and the power consumed accounts for 75% of the module. It can be said to be a very important part of the ...

LED TV backlight technology
2021-05-10
LED are made by replacing CCFL cold cathode fluorescent tubes with light-emitting diodes to achieve a better lighting display. However, LED backlighting has evolved since then, so it is used for three main types, with different display effects.A. Direct Down LED Backlight (DLED backlight)The main feature is that the backlight panel is covered with LEDs for uniform illumination. Character...
