A display device includes data lines transmitting data voltages, a signal controller processing image data from an external device and generating control signals, a gray voltage generator generating gray voltages, and a data driver selecting a gray voltage corresponding to image data from the signal controller and applying the gray voltages to the data lines as the data voltages. The signal controller compares present data with previous data of the image data and generates first to fourth mode setting signals for application to the data driver responsive to a result of the comparison.

An LCD corrects deviations in pixel kickback voltages caused by delays in gate driving signals. The LCD includes a timing controller generating first and second output enable signals, first and second level shifters respectively generating first and second gate clock pulses and inverted clock pulses, and first and second gate drivers respectively generating first and second gate driving signals. A precharge time of the first gate driving signals is controlled by the pulse width of the first output enable signal and a precharge time of the second gate driving signals is controlled by the pulse width of the second output enable signal.

摘要:
A gate drive portion for a display device including multiple pixels having first and second sub-pixels includes a first shift register generating a first output signal in response to a first gate clock signal, a second shift register generating a second output signal in response to a second gate clock signal, a level shifter coupled to the first and second shift registers and amplifying the first and second output signals, and an output buffer coupled to the level shifter and generating first and second gate signals. The first gate signal is generated in synchronization with the first gate clock signal and the second gate signal is generated in synchronization with the second gate clock signal. Accordingly, the charging time of the first and second sub-pixels may be improved by separately driving the odd-numbered and even-numbered sub-pixels and the visibility of the LCD device may also be improved.
