    摘要: A liquid crystal display has a liquid crystal layer, first and second electrodes, and a third electrode. The liquid crystal layer is inserted between the first and second electrodes to define liquid crystal cells. The third electrode is capacitively coupled with one of the first and second electrodes. A correction voltage for correcting distortion of a waveform for driving one of the first and second electrodes is applied to the third electrode, to keep an effective voltage applied to the liquid crystal cells unchanged and improve the display quality of the liquid crystal display. Therefore, the liquid crystal display of the present invention can correct distortion of a common voltage and prevent crosstalk.

    摘要: In a driving device of an active matrix type liquid crystal display unit including a liquid crystal display panel, a scan driver, and a data driver, a data voltage controlling apparatus is provided to achieve digital multiple gray-scale levels with little flickering. The data voltage controlling apparatus supplies the data driver with a combination of two different data voltages picked up from a plurality of digital data voltages previously set. The combination of two different data voltages are, for example, a combination of different waveforms, a combination of negative level and positive level, and a combination of two different voltages having at least a voltage difference. Further, a division of T-V characteristics and an exchange of data voltages are carried out to reduce the flickering.
