Abstract
The present invention relates to a display device and a driving method thereof. A display device according to exemplary embodiments of the present invention includes: a signal controller to process an input image signal and an input control signal to control output of a digital image signal; a gray voltage generator to generate a gray reference voltage; and a data driver to generate gray voltages based on the gray reference voltage from the gray voltage generator, to receive the digital image signal, and to output a portion selected from the generated gray voltages as a data voltage, wherein the gray reference voltage includes a first gray reference voltage for the input image signal and a second gray reference voltage for an insertion gray, and the gray voltage generator generates one of the first gray reference voltage or the second gray reference voltage according to the selection signal included in the control signal to be provided to the data driver.
