The Chinese character explanation of LED is "light cannot shine directly" or "escape the direct shine of light".
In the electronics industry, backlighting is a lighting method, often used for LCD flashing. The difference between the backlight type and the front light type is that the backlight is shining from the side or discord, while the front light is shining from the front. They are used to increase the illuminance in a low-light environment and the brightness of computer flashes and liquid crystal screens to generate light in a similar way to CRT flashing.

The light source may be incandescent bulbs, electro-optical panels (ELP), light-emitting diodes (LED), cold cathode tubes (CCFL), etc. The electro-optical panel supplies uniform light across the entire surface, while other backlight modules use diffusers to supply uniform light from uneven light sources.
LEDs can be in any color, and monochromatic liquid crystals generally have backlights such as yellow, green, blue, and white. The colorful flashing uses white white light because it contains a lot of color light.
LED lamp beads are used in fine and cheap LCD panels. His light is generally colored, although the white backlight has become more widespread. Electro-optical panels are often used in large-scale flashes. At this time, uniform backlighting is very important. The electro-optical panel needs to be driven by high-voltage alternating current, which is supplied by the inverter circuit. Cold cathode tubes are used in computer flashes, and the color is generally white. This also requires inverters and diffusers. The incandescent backlight is used when high brightness is required, but its drawback is that the life of the incandescent bulb is appropriately limited, and an appropriate amount of heat is generated.
