DISPLAYING ALWAYS ON DISPLAY-RELATED CONTENT

摘要

Systems and methods for displaying always-on content on a display of a mobile device allow the device to use a low power processor for certain always-on content and to coordinate with the device application processor for the remaining always-on content. In an embodiment, a pixel row-skip pattern is specified by the low power processor based on the display screen's resolution setting as well as ambient light conditions. In a further embodiment, the execution of pixel rendering in keeping with the prescribed pattern is synchronized between the device's low power processor and main application processor.

主权项

1. A method of drawing content to a display of a mobile communication device in a low power mode wherein the mobile communication device has a low power processor and a higher power application processor, the method comprising:
detecting at the mobile communication device a triggering event signaling that the content is to be drawn to the display; determining a resolution setting of the display; detecting an ambient light level at the device; based on the determined resolution setting of the display and the detected ambient light level at the device, generating a pattern of display pixel rows to be skipped during rendering; and drawing a first subset of the content to the display via the low power processor in accordance with the generated pattern and drawing a second subset of the content to the display via the device application processor in accordance with the generated pattern.
