Abstract:
1. A display apparatus, comprising: a pixel array section including a plurality of gate lines extending in a direction of a row, a plurality of signal lines extending in a direction of a column, and a plurality of pixels arranged in rows and columns at points at which said gate lines and said signal lines intersect with each other; a vertical drive circuit connected to said gate lines for successively selecting said pixels for each row within a predetermined vertical scanning period; a video line for supplying a video signal; a sampling switch connected between said video line and each of said signal lines; a horizontal drive circuit for successively driving the sampling switches within a predetermined horizontal scanning period to write the video signal dot-sequentially into the pixels of the selected row; a precharge line for supplying a precharge signal; a precharge switch connected between said precharge line and each of said signal lines; and a precharge drive circuit for performing batch precharge wherein said precharge drive circuit drives the precharge switches at a time within a horizontal blanking period preceding to the horizontal scanning period to apply a precharge signal of a first level at a time to said signal lines and sequential precharge wherein said precharge drive circuit successively drives the precharge switches within the horizontal scanning period to successively apply a precharge signal of a second level to said signal lines.
