Abstract:
A system calibrates luminance of an electronic display. The system includes an electronic display, a luminance detection device, and a controller. The luminance detection device is configured to measure luminance parameters of active sections of the electronic display. The controller is configured to instruct the electronic display to activate sections in a sparse pattern and in a rolling manner and instruct the luminance detection device to measure luminance parameters for each of the active sections in the sparse pattern. The controller generates calibration data based on the measured luminance parameters of sections in the sparse pattern.
