US 2026/0087982 A1 · Systems and Methods for Adaptive Peak Luminance Control

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.

Dependent claims

An electronic device, comprising:

an electronic display configured to drive a plurality of pixels;
and
image processing circuitry comprising:
current control circuitry configured to determine current to be drawn or projected to be drawn by the electronic display at a line-by-line granularity and to adjust image data to prevent current overdraw;
frame-delayed current control circuitry configured to perform content-adaptive tone mapping of subsequent frames to prevent current overdraw for the subsequent frames;
and
burn-in compensation circuitry coupled to an output of the frame-delayed current control circuitry and coupled to an input of the current control circuitry.
