The interpretation of the Chinese characters in the backlight is "the light cannot be directly irradiated" or "to avoid the direct irradiation of light".
In the electronics industry, backlight is a form of lighting and is often used on LCD display. The difference between the backlight and the front light is that the backlight is irradiated from the side or behind the back, while the first figurine is illuminated from the front. They are used to increase the lighting degree in the low -light source and the brightness on the computer display, the LCD screen, and generate light in a similar way to display in a CRT.
Its light sources may be incandescent light bulbs, electric light panels (ELP), luminous diode (LED), cold cathode pipe (CCFL), etc. Electric light panel provides uniform light on the entire surface, while other backlight modules use the astigmatism to provide uniform light from an uneven light source.
Backlight can be any color, monochrome LCDs usually have backlights such as yellow, green, blue, and white. The color display uses white white light, because it covers the most color light.
LED backlight is used on a small, cheap LCD panel. His light is usually colorful, although white backlight has become more and more common. Electric light panels are often used in large display, and uniform backlights are important at this time. Electric light panels need to be driven by high -voltage AC power. Cold cathode pipes are used like a computer display, and the color is usually white, which also needs to be used to use the flowers and astigmatisms. Cure backlight is used when it needs high brightness, but its disadvantage is that the life of the incandescent bulbs is quite limited, and it will generate quite a lot of calories.
