Claim Text:
1. A driving device for a display unit which displays an image based on a video data signal during each frame display period including a data scanning period and a blanking period, comprising: a data driver that applies pixel drive voltages respectively corresponding to luminance levels of each pixel based on said video data signal to multiple data lines of said display unit in each horizontal scanning cycle during said data scanning period as long as power supply thereto is kept; and a drive controller that performs power supply to said data driver and superimposes a reference timing signal on said video data signal and supplies the video data signal to said data driver, wherein said data driver comprises: wherein said drive controller stops the power supply to said clock data recovery circuit and said data taking-in unit for a first power stop period within said blanking period, and stops the power supply to said pixel-driving voltage outputting unit for a second power stop period within said blanking period.
