Abstract:
1. A data signal line driving method where n, n>1, video signal lines supply a multiphased video signal in parallel to m, m>1, data fetching blocks, each data fetching block fetching the multiphased video signal into n data line groups and each data line group including p, p>1, sequential data signal lines and driving p corresponding sequentially adjoining sections of a display, the data signal lines each having an associated sampling switch that connects each data signal line to a video signal line such that the p sequential data signal lines of each data line group are connected to the same video signal line and p sequential data signal lines are alternately connected to the same video signal line with an interval of another ((n−1)×p) data signal lines therebetween, the p sampling switches associated with a given data line group each responsive to a different sampling pulse, and p shift registers provided with respect to each data fetching block with the shift registers being connected between blocks such that the blocks are driven sequentially, said method comprising: fetching the multiphased video signal from the video signal lines, via p sampling pulses, into the data signal lines in each block in response to one or more timing pulses generated by the p shift registers provided with respect to the block, and driving the blocks sequentially, there being performed a first driving in which the p shift registers in each block are driven sequentially to provide p sequential timing pulses and each sampling pulse in the block being responsive to a corresponding timing pulse such that the sampling pulses in the block are activated sequentially, and there being performed a second driving in which only one shift register in the block is driven to provide one timing pulse and all sampling pulses in the block are responsive to the one timing pulse such that all sampling pulses in the block are activated simultaneously.
