Abstract
A display device driver includes: a pixel drive voltage application unit; and a delay controller. The pixel drive voltage application unit converts a plurality of pixel data pieces into a plurality of pixel drive voltages, the pixel data pieces respectively representing luminance levels of respective pixels based on a video signal, the pixel drive voltages respectively having voltage values corresponding to the luminance levels, and applies the converted pixel drive voltages to the display device. The delay controller controls the pixel drive voltage application unit to apply the plurality of pixel drive voltages to the display device, the plurality of pixel drive voltages being sequentially delayed in units of groups, the groups each including t pixel drive voltages, and sets delay time designated by delay time designation signals as delay time to delay each of the pixel drive voltages.
