TCS34103M

TCS34103M is a universal ambient light RGB sensor with selective flicker detection for use behind OLED displays or as an auxiliary to a camera. The ambient light sensing function provides three concurrent ambient light and flicker sensing channels, which can be arbitrarily connected to the photodiodes via a programmable multiplexer. It incorporates a set of RGB photodiodes and a Clear photodiode. The RGB and Clear photodiode area is covered with a UV/IR blocking filter. The device also integrates direct detection of ambient light flicker. Flicker detection is executed in parallel with ambient light sensing and has an independent gain configuration. The flicker detection engine will sample and buffer data for calculating flicker frequencies externally on a host CPU. Applications include indoor/outdoor brightness information, brightness management for displays, camera image correction assistance, and flicker-immune camera operation.
