Abstract
A display driver includes a timing controller and a drive circuit. The timing controller receives an external horizontal sync signal and generates an internal horizontal sync signal based on the external horizontal sync signal. The drive circuit drives a display panel in synchronization with the internal horizontal sync signal. Generating the internal horizontal sync signal includes: generating a first pulse of the internal horizontal sync signal in response to detection of a first pulse of the external horizontal sync signal after a masking period has expired, wherein the masking period starts when a first previous pulse is detected in the external horizontal sync signal; and generating a second pulse of the internal horizontal sync signal in response to detection of a second pulse of the external horizontal sync signal in a non-masking period which starts when a second previous pulse is detected in the external horizontal sync signal.
