Abstract
An aspect of the present invention proposes a novel approach that can reduce the total number of the overlays to be composited during the display of graphical output in a mobile computing device. As a result, the total number of memory bandwidth and the usage of a graphics processing unit by a pre-compositor can be decreased significantly. According to one embodiment, this new approach is implemented with a display panel with embedded memory which supports a partial update, or refresh feature. Which such a feature, the layer compositor (typically either the display controller or GPU) is able to keep track of actively updating regions of a display panel by checking if each layer has new content to be displayed.
