Display BacklightsA display backlight is a light source that is used to illuminate the screen of an electronic display, such as a TV, computer monitor, or smartphone. The backlight is typically located behind the display and shines through the pixels of the display, providing the light needed to make the image visible. Backlights come in a variety of different technologies, such as cold cathode fluorescent lamps (CCFLs) or light-emitting diodes (LEDs). They can be used in both LCD and OLED displays, and are an essential part of the display system. In recent years, LED backlights have become increasingly popular, as they are more energy efficient and can be more easily controlled to produce different colors and brightness levels. Overall, display backlights are an essential component of electronic displays, and are key to producing clear and vibrant images on screen.
