  • Publication number: 20140022234
    Abstract: There is provided a display device capable of displaying an image that barely changes with low power consumption on the basis of video data included in a transmitted command, and there is also provided a method for driving the same. A display timing controller (31) determines every frame period whether or not an externally transmitted command includes updated video data. As a result, when it is determined that no updated video data is included, screen refreshing is paused by not reading video data stored in frame memory (36). Moreover, when it is determined that updated video data is included, screen refreshing is performed by reading video data stored in the frame memory (36).

  • Publication number: 20130100007
    Abstract: A shift register 10 is configured such that m unit circuits 11 each including a shift unit 12 and three buffer units 13r, 13g, and 13b are in a multi-stage cascade connection and that 3m signals in total including three signals from each stage are outputted. The m shift units 12 perform a shift operation, and a first signal Y is outputted from each stage. When a clock signal CK is at a high level, the first signal Y rises higher than a normal high level due to bootstrapping. The buffer unit 13r controls an output signal YR to be at a high level based on the buffer control signal CR and the first signal Y. A buffer control circuit 7 controls buffer control signals CR, CG, and CB to be at a high level for a time period shorter than a half cycle of the clock signal. With this, a shift register with a reduced circuit amount and low power consumption is provided.
