Abstract

In certain image processing circuitry, pixel burn-in compensation (BIC) circuitry may be disposed prior to a frame-delayed current control circuitry. This may result in inaccurate burn-in compensation, as burn-in compensation is determined based at least in part on the pixel values, which may be adjusted during pixel modification via the frame-delayed current control circuitry. Accordingly, in an embodiment, burn-in compensation may be disposed after the frame-delayed current control circuitry, such that the BIC circuitry calculates burn-in compensation values based on more accurate (e.g., post-pixel modification) pixel values. This is particularly important with respect to the frame-delayed current control circuitry, as the effects of the frame-delayed current control circuitry may remaining visible on screen for several seconds, negatively impacting user experience.
