Zusammenfassung:Certain display types-such as organic light emitting diode (OLED) displays-may be more prone to burn-in or ghosting due to the varied luminance degradation rates of pixel cells of the display-especially in applications or content types that require display of prolonged, continuous, static textures. To account for this, aging of pixel cells (e.g., R, G, B, and/or W pixel cells) of a display may be tracked such that more aged pixel cells may be compensated for by reducing pixel values of one or more (e.g., each) other pixel cells of the display. As a result, the effect of burn-in or ghosting may be mitigated by tracking luminance degradation over time and compensating for the luminance degradation across some or all of the pixel cells of the display.
