SYSTEMS AND METHODS OF PIXEL CALIBRATION BASED ON IMPROVED REFERENCE VALUES

摘要

What is disclosed are systems and methods of compensation of images produced by active matrix light emitting diode device (AMOLED) and other emissive displays. The electrical output of a pixel is compared with a reference value to adjust an input for the pixel. In some embodiments an integrator is used to integrate a pixel current and a reference current using controlled integration times to generate values for comparison.

1. A method for compensating an image produced by an emissive display system having pixels, each pixel having a light-emitting device, the method comprising:
integrating a pixel current output from the pixel for a pixel integration time generating an integrated pixel current value; comparing the integrated pixel current value with a reference signal, generating at least one comparison value; and adjusting an input for the pixel with use of the comparison value.
