DRIVING DEVICE AND DISPLAY APPARATUS HAVING THE SAME

摘要

A driving device and a display device having the same are provided to lengthen a display period within one frame by setting a second clock applied to a data driver to have a frequency lower than that of a first clock. A timing controller(110) receives a first clock and a first image data signal, generates a second clock having a lower frequency than a frequency of the first clock and a second image data signal, and outputs a data control signal and a gate control signal. A data driver(140) receives the second image data signal in synchronization with the second clock from the timing controller, the data driver converting the second image data signal into a pixel voltage. A gate driver(150) outputs a gate voltage in response to the gate control signal. A phase synchronization loop(130) generates the second clock having the lower frequency than the frequency of the first clock by a predetermined value.
