Title:
METHODS AND APPARATUS TO RECOVER A MOBILE DEVICE WHEN A COMMAND-MODE PANEL TIMING SYNCHRONIZATION SIGNAL IS LOST
Document Type and Number:
WIPO Patent Application WO/2021/026868
Kind Code:
A1
Abstract:
The present disclosure relates to methods and apparatus for display processing. For example, disclosed techniques facilitate recovering a mobile device display when a command-mode panel timing synchronization signal is lost. In some examples, disclosed techniques may facilitate operation of a host processor. Example techniques disclosed herein can monitor for a display exception associated with a display panel operating in a command-mode. Example techniques disclosed herein can also determine whether a transmission timeout occurred in response to detecting a display exception. Further, example techniques disclosed herein can perform a display panel check in response to determining that the transmission timeout occurred. Example techniques disclosed herein can switch the display panel from operating in the command-mode to operating in a video-mode based on the display panel check.
