Lumex LED Backlighting
LED backlighting is the use of LED (light emitting diode) technology to provide light behind an LCD or other type of display. LED backlighting helps provide a brighter picture and is more energy efficient than traditional CCFL (cold cathode fluorescent lamp) backlighting. LED backlighting can be implemented in a variety of ways, such as a full array, local dimming, edge lighting, and remote phosphor lighting. Each method affects the picture quality and power consumption differently. The most common type of LED backlighting is full array, which provides uniform illumination as well as local dimming. Local dimming allows the LEDs to be dimmed or turned off in certain areas to achieve better contrast and produce darker blacks in the picture. Edge lighting uses LEDs arranged around the edges of the LCD to provide illumination across the entire display. Remote phosphor lighting uses a light engine and phosphor material to create an efficient backlighting solution.
