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.
