Unlike cold cathode fluorescent lamps (CCFLs), which provide the light that shines through the pixels of traditional LCD panels, LEDs produce a purer white light, and with larger displays the LEDs can be spread out in a grid behind the display to provide a more uniform glow. And by employing color (RGB) LEDs in the grid, manufacturers can actually heighten the color response of the panel. LED-based LCDs can easily exceed 100 percent of the possible colors in the television specs spelled out by the NTSC, pushing them beyond standard RGB (sRGB) and into the higher end of the color spectrum-the Adobe RGB and CMYK profiles favored by professional designers.
