Color Controller Integrates RGB Photosensor August 2006 Issue Published Date: August 21, 2006
The 5 mm x 5 mm x 0.75 mm ADJD-J823 debuts as the first color controller with an integrated color photosensor for backlighting LCDs, making it attractive for use in a plethora of portables with display screens measuring 7" diagonal or smaller. Operating on voltages as low as 2.5V the device forecasts 25% richer colors than CCFL backlighting without the traces of mercury found in CCFLs. The CMOS mixed-signal IC is designed to be the closed loop optical feedback device of an RGB LED-based backlighting system. It exhibits a wide gain control and uses an algorithm to automatically select the optimum gain. Price is less than $10 each in low volumes. AVAGO TECHNOLOGIES, Santa Clara, CA. (800) 235-0312.
