Edid shadowing techniques for fast display startup

摘要

Techniques are provided for improving electronic display startup time using extended display identification data (EDID) shadowing. In one example, a method for starting an electronic display may include accessing, by a timing controller, EDID from a memory device. The method may also include storing EDID from the memory device in the timing controller. The method may include, after storing EDID from the memory device, transmitting a signal from the timing controller to a host device to indicate that the host device can access the stored EDID. The method may also include accessing, by the timing controller, configuration data from the memory device. The method may include, after transmitting the signal to the host device, transferring the EDID stored in the timing controller to the host device while the timing controller is accessing the configuration data resulting in reduced startup time of the electronic display.

1. A method for starting an electronic display of an electronic device comprising:
accessing, by a timing controller of the electronic display, extended display identification data (EDID) from a memory device in the electronic display; storing the EDID from the memory device in the timing controller; after storing the EDID from the memory device, transmitting a signal from the timing controller to a host device to indicate that the host device can access the stored EDID; accessing, by the timing controller, configuration data from the memory device; and after transmitting the signal to the host device, transferring the EDID stored in the timing controller to the host device while the timing controller is accessing the configuration data.
