Abstract
A display driver includes a memory, a data driver, and a control circuit. The data driver is configured to: in a first mode, update a display panel based at least in part on a command provided to the display driver asynchronously with a display vertical sync signal; and in a second mode, update the display panel based at least in part on first image data stored in the memory in synchronization with the display vertical sync signal. The control circuit configured to: switch from the first mode to the second mode in response to a first command; and, in the second mode, adjust the display vertical sync signal based at least in part on an external vertical sync signal.
