Method and apparatus for optimizing display updates on an interactive display device

摘要

A solution is proposed to perform display updates in a lower power user interface. According to one embodiment, the display panel is placed in the lower possible refresh rate that can be supported. Rendered updates are presented to the displays at the fasted possible pixel rates the communication interface between the rendering component to the display panel can support, and a buffer on the receiving end of the display receives and stores updated frames as they are rendered and transmitted. Subsequent display updates (generated in response to subsequent sensor input, for example) may be created and transmitted as soon as the preceding display frames are buffered. In the meantime, as soon as the update frame is transmitted, the timing controller of the display panel is instructed to interrupt the current refresh period and to immediately rescan the frame.

主权项

1. A method for displaying input in a touch-sensitive display panel, the method comprising:
placing a display panel of a mobile computing device in a low power refresh mode; rendering a display update in response to detecting a sensor input received in the display panel; transmitting the display update to the display panel; buffering the display update in a frame buffer comprised in the mobile computing device; and interrupting a current refresh period of a timing controller of the display panel by rescanning a current frame displayed in the display panel to include the display update from the frame buffer.
