Abstract
Embodiments relate to a display device including pixels arranged in rows and columns, where duty cycles of the pixels are dynamically programmed according to eye tracking information. For a display frame, the display device may determine a gaze region and a non-gaze region based on the eye tracking information. A control circuit of the display device controls a first subset of pixels in the gaze region to operate with a first duty cycle and controls a second subset of pixels in the non-gaze region to operate with a second duty cycle greater than the first duty cycle. The first subset of pixels emits light with greater brightness than the second subset of pixels.
