Abstract:
1. A method for compensating stressed pixels on a display device, the method comprising: receiving a video data input for displaying a video image frame at a first frequency; detecting one or more pixels in the video image frame as one or more stressed pixels; determining compensating brightness for each of the stressed pixels; forming a primary and a secondary sub-frame based on the determined compensating brightness; determining a second frequency based on the determined compensating brightness; displaying the primary sub-frame representing at least a part of the video image frame, the primary sub-frame having the stressed pixels whose brightness is expected to be compensated; and displaying at least one secondary sub-frame having the predetermined stressed pixels thereon with predetermined compensating brightness, wherein the primary and secondary sub-frames are displayed separately and sequentially at the second frequency, which is different from the first frequency, so that the separation of the two sub-frames is not detectable by a viewer.
