Abstract
A display driver includes an amplifier circuit configured to output time-sequentially arrayed first to n-th data voltages to an image-signal input terminal, and a switch-control-signal output circuit configured to output switch control signals that control the first to n-th switches disposed between the image-signal input terminal and respective first to n-th data lines. The switch-control-signal output circuit outputs the switch control signals that turn on two or more switches including a p-th switch (where p is an integer within the range of 2 to n, inclusive) among the first to n-th switches during a first driving period. The amplifier circuit outputs a p-th data voltage among the first to n-th data voltages during the first driving period.
