Abstract:
What is disclosed are systems and methods of optical feedback for pixel identification, evaluation, and calibration for active matrix light emitting diode device (AMOLED) and other emissive displays. Optical feedback is utilized to calibrate pixel whose output luminance exceeds a threshold difference from a reference value, and may include the use of sparse pixel activation to ensure pixel identification and luminance measurement, as well as a coarse calibration procedure for programming the starting calibration data for a fine calibration stage.

Claim (Index 21):
An optical feedback method for calibrating an emissive display system having pixels, each pixel having a light-emitting device, the method comprising:\n iteratively performing a calibration loop until a number of pixels of the display determined to be uncalibrated is less than a threshold number of pixels, the calibration loop comprising: measuring the luminance of pixels of the display generating luminance measurements for each pixel; comparing luminance measurements for the pixels with reference values generating a comparison value for each pixel measured; determining for each pixel whether the pixel is calibrated or uncalibrated based on the comparison value for the pixel; adjusting calibration data for each pixel determined to be uncalibrated with use of the luminance measurement for the pixel and previous calibration data for the pixel; and programming each pixel whose calibration data was adjusted with the adjusted calibration data.
