Abstract
Embodiments presented herein relate to reducing perceivable image artifacts on an electronic display caused by variances in emission timing of emission groups, and more specifically, to emission techniques that can be used with foveated content, such as dynamically foveated content. For example, an image frame may be divided into multiple foveation regions based on viewing characteristics, such as a viewer's gaze. To improve perceived image quality, a first foveation region may use a higher pixel resolution while a second foveation region may use a lower pixel resolution, which may result in differences in programming time. As such, one or more intra-frame pauses may be used when programming the second foveation region to delay emission timing of the second foveation region. In this way, programming time for the image frame may be more consistent and perceivable image artifacts from frame to frame may be reduced.
