    摘要： A liquid crystal display having a plurality of pixels and blocks of shift registers that are connected to one another for temporarily storing data signals and from which the data signal outputs are sequentially applied to drive the pixels. Each of the shift registers receives a shift start signal and at least one of first and second clock signals, of which phases are opposite to each other, and a high period of the shift start signal corresponds to two cycles of the respective clock signals so that each pixel is pre-charged from the data signal from previous block of registers before receiving the data signal for the current block thereby preventing a boundary between blocks from being visually recognized.

    摘要： An LCD device includes an LCD panel, a source driving part, an operating part, a mean voltage generating part, and a pre-charging part. The LCD panel includes a switching element and a liquid crystal capacitor. The switching element is formed in a region defined by gate and source lines adjacent to each other. The liquid crystal capacitor is electrically connected to the switching element. The source driving part converts data signals into data voltages of analog type. The operating part determines a mean data signal of the data signals. The mean voltage generating part converts the mean data signal into a mean data voltage of analog type. The pre-charging part selectively applies the data voltages and the mean data voltage to the source lines, thereby improving an image display quality of the LCD device.
