Abstract
Techniques for generating pixel shifting patterns for organic light emitting diode (OLED) displays are provided. Pixel usage data for the OLED display can be accumulated. Areas of the OLED display susceptible to burn-in damage can be identified based on the accumulated pixel usage data. A pixel shifting pattern can be generated based on the accumulated pixel image data and data relating to an image to be displayed. The pixel shifting pattern can be generated to avoid the areas identified as susceptible to burn-in damage. The pixel shifting pattern can be applied to the image to be displayed to generate modified image data. The modified image data can limit further damage to the OLED display and thereby delay the onset of undesirable burn-in effects.
