  • Patent number: 9542902
    Abstract: A display device driver that can display images while preventing noise and suppressing display unevenness is provided. When pixel drive voltages corresponding to the luminance levels of respective pixels indicated by a video signal are applied to the data lines of the display device, the pixel drive voltages are applied to data lines that intersect the scanning lines of the display device at positions where the delay time is larger, at timing later than timing of applying the pixel drive voltages to the data lines that intersect the scanning lines at positions where the delay time is smaller, the delay time being a period of time between start of application of the scanning pulse by the scanning driver and actual arrival of the scanning pulse.

  • Publication number: 20150221274
    Abstract: First to N-th latches capture N pieces of pixel data indicative of the luminance levels of respective pixels in synchronization with first to N-th capture clock signals each having different edge timing. Voltages corresponding to the pieces of pixel data output from the first to N-th latches are applied to each of the data lines of the display device. In this case, first to N-th flip-flops formed in an N-stage shift register capture a single pulse load signal which is synchronized with a horizontal synchronizing signal in a video signal while sequentially shifting the load signal to subsequent stages in synchronization with a reference timing signal supplied from the outside. Outputs of the first to N-th flip-flops in the N-stage shift register are supplied as first to N-th capture clock signals, to the first to N-th latches, respectively.
