Abstract: A display device is disclosed, which may supply gate signals to allow pulse widths of gate signals supplied to adjacent gate lines to be overlapped with each other and at the same time minimize cost increase caused by increase of the number of line memories. The display device comprises a display panel, a gate driver and a timing controller. The display panel includes gate lines, data lines and pixels provided at crossing areas between the gate lines and the data lines. The gate driver supplies gate signals to the gate lines. The timing controller supplies a start signal and gate clock signals for controlling an operation timing of the gate driver to the gate driver. One frame period includes an active period for supplying the gate signals to the gate lines and a vertical blank period for not supplying the gate signals to the gate lines, and the start signal is supplied within the vertical blank period.

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.
