摘要： A timing controller includes a receiver and a clock generator connected to output terminals of the receiver. The clock generator receives an external clock signal through the receiver and periodically modulates a frequency of the external clock signal to generate a modulation clock signal that is used to process a plurality of pixel data. The clock generator controls a delay time of the modulation clock signal based on a modulation rate of the frequency of the modulation clock signal. According to the timing controller, circuit blocks connected to output terminals of the clock generator are operated by the modulation clock signal. Thus, the circuit blocks operated by the delayed modulation clock signal may be prevented from malfunction due to electromagnetic interference.

摘要： 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 liquid crystal display includes first and second opposing spaced insulating substrates, pixel electrodes formed on the first substrate, a common electrode formed on at least one of the first and second substrates, and a liquid crystal layer interposed there between the first substrate and the second substrate. In this structure, each pixel electrode is divided into a main-pixel electrode and a sub-pixel electrode, to which different signal voltages are individually applied at the same gray scale. Further, a signal voltage to be applied to the sub-pixel electrodes is determined by a gamma value satisfying the following equation: Gamma K=(current gray scale/maximum gray scale)f F(Gray Scale)=a×(maximum gray scale/current gray scale), wherein a is a constant.
