Abstract: An exemplary embodiment of present disclosure provides a display device including a first horizontal line, a first delay line, a second delay line, a delay value determiner, and a timing controller. The first horizontal line receives a gate pulse signal (CPV) generated by a gate driver. The first delay line is connected to the first horizontal line to transmit a gate pulse signal received at a first horizontal position as a first delay signal. The second delay line is connected to the first horizontal line to transmit a gate pulse signal received at a second horizontal position as a second delay signal. The delay value determiner generates a horizontal delay signal based on the first delay signal and the second delay signal. The timing controller determines generation times of line latch signals applied to a plurality of data lines based on the horizontal delay signal.

Abstract: A display device includes a display unit including a light emitting device, data and gate driver for respectively applying data and gate voltages to the display unit, and a signal controller for transmitting, to the data driver, image data having a clock embedded therein. The data driver recovers a first internal reference clock during a low period of a first frame control signal, using the image data having the clock embedded therein, compares the frequency of the recovered first internal reference clock with the frequency of a previously stored reference clock, when the frequency of the recovered first internal reference clock is within an error range of the frequency of the previously stored reference clock, outputs the recovered first internal reference clock and receives a second frame control signal, and when the second frame control signal corresponds to a CDR unit operating condition, recovers a second internal reference clock.
