Hybrid graphics display power management

Abstract

Some embodiments describe techniques that relate to hybrid graphics display power management. In one embodiment, data corresponding to one or more image frames of a video stream are stored in a local frame buffer. A display device (e.g., an LCD) may then be driven based on the stored data in the local frame buffer or a video stream from a graphics controller. Other embodiments are also described.

Description

technical field [0001] The present disclosure generally relates to the field of electronics. More specifically, embodiments of the invention relate to hybrid graphics display power management. Background technique [0002] Portable computing devices are gaining popularity, in part because of their falling prices and increasing performance. Another reason for their increasing popularity may be due to the fact that: [0003] Some portable computing devices can operate in many places, for example by running on battery power. However, as more functionality is integrated into portable computing devices, the need to reduce power consumption becomes increasingly important, such as maintaining battery power for extended periods of time. [0004] Also, some portable computing devices include liquid crystal displays (LCDs) or "flat panel" displays. Current mobile devices are generally designed to be "always ready" to update the display with new frames. While this readiness state ...

Problems solved by technology

While this ready state is great for visual performance needs, the resulting power becomes wasted when the system is idle (for example, when the image on the display does not change for a given period of time)
