نور پس زمینه چیست؟ نور پس زمینه به چه چیزی اشاره دارد؟

  Backlights are now used in many electronic products, most commonly for LCD displays. Backlit light is illuminated from the side or the back. While the front-lit type is illuminated from the front, the backlight type is also used to increase the illumination in low-light environments and the brightness of computer monitors and LCD screens, producing light in a similar way to CRT displays. So what exactly is a backlight? Let's find out together next.

  The backlight source may be an incandescent light bulb, an electro-optic panel (ELP), a light emitting diode (LED), a cold cathode tube (CCFL), or the like. Electro-optical panels provide uniform light across the entire surface, while other backlight modules use diffusers to provide uniform light from uneven sources.

 The backlight can be any color, and the monochrome liquid crystal usually has a backlight such as yellow, green, blue, and white. The color display uses white white light because it covers the most color light.

  LED backlights are used in small, inexpensive LCD panels. His light is usually colored, although white backlighting has become more common. Electro-optical panels are often used on large displays where uniform backlighting is important. Electro-optical panels need to be driven by high-voltage alternating current, which is provided by an inverter loop. Cold cathode tubes are used in things like computer monitors, which are usually white in color, which also requires inverters and diffusers. Incandescent backlights are used when high brightness is required, but have the disadvantage that incandescent bulbs have a rather limited lifespan and generate considerable heat.
