Abstract
In a display controller for generating a video sync signal using an external clock, he display controller includes an initializer configured to initialize an internal parameter in response to a frame start signal. A sync signal generation circuit is configured to count the external clock, increase the internal parameter, and generate the video sync signal according to a result of comparing the internal parameter that has been increased with a setting value. An original use of the external clock may not be generating the video sync signal.
