What is the led backlight?
Jul 03, 2018
The backlight (back light) is actually a high-brightness illuminator with a combination of a fluorescent lamp and a reflector on the back side of the liquid crystal LCD. Because the liquid crystal panel of the LCD liquid crystal display does not emit light, it can only transmit light. Add a bright illuminator to the back.
Although the optical mechanism of the backlight board seems simple, the optical characteristics, size and relative position of each component form a loop-like interlocking relationship with the overall optical performance of the backlight panel, so that it is oriented toward a thin shape and high efficiency. At the same time, how to simplify the mechanism and simplify the process while improving the optical performance is an important technical key for the future development of the backlight panel.
The backlight is a back light that changes the screen in front and the backlight is a liquid crystal LCD. The LCD panel of the LCD liquid crystal display does not emit light and can only transmit light, so it is necessary to add a bright illuminator on the back side. This is the backlight board, which is actually a fluorescent lamp plus a reflector.
