RESCHEDULING ACTIVE DISPLAY TASKS TO MINIMIZE OVERLAPPING WITH ACTIVE PLATFORM TASKS

摘要

In general, in one aspect, a mobile device display includes panel electronics, a backlight driver and a rescheduler. The panel electronics is to generate images on an optical stack of the display based on input from a processing platform of the mobile device. The backlight driver is to control operation of a backlight used to illuminate the optical stack so that the user can see the images generated on the display. The rescheduler is to determine when a timing critical task of the processing platform overlaps with a non-timing critical task of the panel electronics or the backlight driver and reschedule the non-timing critical task until the timing critical task is inactive or a visual tolerance limit has been reached. The rescheduling minimizes overlap between the timing critical tasks and non-timing critical tasks and accordingly reduces power consumption without effecting performance or impacting a user's visual experience.
