Abstract
A matrix type display apparatus includes pixel electrodes arranged in a matrix, data signal lines and scanning signal lines for driving the pixel electrodes, and a data signal line driving circuit. The data signal line driving circuit includes sampling capacitors for keeping sampled data obtained by sequentially sampling image data over one horizontal scanning period, holding capacitors for holding the sampled data transmitted from the sampling capacitors upon termination of the horizontal scanning period and then outputting the sampled data to data signal lines, and a precharging circuit for precharging the corresponding holding capacitors by applying a predetermined voltage to the holding capacitors before the sampled data is transmitted to the holding capacitors.
