  • Patent number: 9812090
    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.
