Abstract
Systems and methods for improving perceived image quality of an electronic display communicatively coupled to an image data source that outputs a synchronization control signal, which indicates when an image frame is expected to stop being written, based on a source clock signal. The electronic display includes a display pixel row, a display driver, and a timing controller. The timing controller determines a target scan time to be used to write the image frame to the display pixel row and instructs the display driver to write the image frame to the display pixel row based on the target scan time and a display block signal, in which the timing controller instructs the display driver to continue writing the image frame to display pixel row after the electronic display receives the synchronization control signal when the synchronization control signal is received before the target scan time is reached.
