Abstract:
1. A display device, comprising: a plurality of shift register sections, each being configured to sequentially generate a sampling pulse on the basis of a clock signal for writing video signals into pixels; a first pixel block including a first plurality of pixels; a second pixel block including a second plurality of pixels; video signal lines for supplying video signals for each of the first plurality of pixels and the second plurality of pixels; a plurality of data lines each connecting a corresponding one of the video signal lines with a respective one of the first plurality of pixels and the second plurality of pixels; and switch sections provided for the data lines, and located between respective ones of the video signal lines and the data lines, wherein: (a) each of the plurality of shift register sections includes an even number of shift registers, and include a signal forming circuit configured to output one sampling pulse based on a combined output of the plurality of shift registers; (b) the one sampling pulse is generated by each of the plurality of shift register sections; (c) substantially all of the sampling pulses are generated based on one of: (d) the first pixel block is supplied with a first sampling pulse generated from a first shift register section having an even number of shirt registers; and (e) the second pixel block is supplied with a second sampling pulse generated from a second shift register section having an even number of shift registers wherein a first plurality of video signals are simultaneously written into the first plurality of pixels in the first pixel block based on one sampling pulse generated by the first shift register section which includes an even number of shift registers, and wherein: (a) one sampling pulse supplied to each of the pixel blocks is allowed to perform control of each of the switch sections which corresponds to one of the pixels in each of the pixel blocks; and (b) when a certain one of the pixel blocks is supplied with the video signals, the switch sections, each corresponding to one of the pixels in the certain one of the pixel blocks, are simultaneously turned on, so that respective video signals are supplied to the pixels in the certain one of the pixel blocks.
