Abstract: A method, an apparatus, and a computer-readable medium for displaying a blinking cursor are provided in a power-efficient manner. Various hardware and protocol command enhancements are provided allowing a visible cursor frame region and an invisible cursor frame region are sequentially displayed creating the blinking cursor effect. Further support is provided for compressed frames, for example, frames compressed with the VESA Display Stream Compression (DSC) standard.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a power efficient display architecture. A display processor may obtain an indication that UC is to be displayed at a first resolution or a second resolution, where the first resolution is higher than the second resolution. The display processor may drive a first display via a first controller of a first DPU based on the indication. The display processor may drive a second display via a controller of a second DPU if the UC is to be displayed at the first resolution, or drive the second display via a second controller of the first DPU if the UC is to be displayed at the second resolution.
