Abstract
A matrix display apparatus includes a matrix of pixels divided into a plurality of groups of pixels and data signal lines for delivering a data signal to a pixel. The data signal lines are distributed along the direction of a column. The apparatus also includes scanning signal lines for applying a scanning signal to a pixel, the scanning signal lines being distributed along the direction of a row. The apparatus also includes a first switch, disposed from each of the plurality of pixels, for allowing the data signal to be applied to the corresponding pixel based on the scanning signal. The apparatus also includes a second switch, disposed for each of the pixels in at least one of the plurality of the pixel groups, for controlling a timing for allowing the data signal to be applied to the corresponding pixel. The second switch is connected in series to the first switch between the first switch and the data signal line. The apparatus further includes a data signal line driver for sampling an image signal for each of the plurality of scanning signal lines at a predetermined timing within a horizontal scanning period for the corresponding data signal line and for outputting the sampled image signal to the corresponding data signal line as the data signal, the data signal being applied to at least one of the plurality of the pixel groups for a horizontal scanning period and a portion of an adjacent horizontal scanning period.
