Abstract: The present disclosure relates to display devices and methods of driving the display devices. In accordance with embodiments of the present disclosure, it is possible to improve image quality of a display device by reducing a sensing time for sensing one or more characteristic values of at least one driving transistor disposed in at least one sub-pixel. Further, it is possible to perform optimal sensing and compensation for at least one driving transistor by setting a minimum sensing time for one or more characteristic values of the at least one driving transistor and changing the sensing time according to a sensing available time of the display device.

Abstract: An LCD device and a driving method thereof are provided. The LCD device includes a plurality of data driver ICs, a timing controller, a reference voltage generator, and a PCB. The data driver ICs include a gamma voltage generator which generates a gamma voltage. The timing controller generates an EPI packet for controlling the data driver ICs. The reference voltage generator reduces the driving voltage, and supplies the reduced driving voltage to the data driver IC. The reference voltage generator, the data driver ICs, and the timing controller are mounted on the PCB. A first transmission line which connects the reference voltage generator and the data driver ICs, and a second transmission line which connects the timing controller and the data driver ICs are formed on the PCB.
