LED technology offers better color mixing and simplified thermal management for backlighting large LCD displays.

Thye-Linn Mok, Avago Technologies

Cold-cathode fluorescent lamps still are the industry standard for backlighting color LCD monitors and TVs, even though red, green and blue (RGB) LEDs have been demonstrated to bring benefits. When LEDs are combined with a color-management feedback controller, they can achieve a superior color gamut, more consistent brightness over time and temperature, and longer useful life than the lamps; they also can incorporate features such as a tunable white point. In addition, LED backlighting eliminates the traces of mercury found in cold-cathode fluorescent lamps, thus meeting mandates for the...Read full article
