Abstract: At the time of partial drive, the levels of voltages applied to data lines SL1 to SLn are switched according to a rewrite frequency set for each region of a display screen. For example, in a still-image display region with a relatively low rewrite frequency, the levels of the voltages applied to the data lines SL1 to SLn are set to be higher than those for a moving-image display region with a relatively high rewrite frequency. By this, the same effect as that obtained when a counter voltage is switched according to the rewrite frequency can be obtained. Thus, flicker occurring in each region of the display screen can be suppressed.

Abstract: In a display control circuit (200) of a display device, an image pattern detection portion (230) detects whether an image is an anti-flicker pattern or not, and when it is an anti-flicker pattern, a backlight source is driven (typically, such that its luminance changes in the opposite phase relative to luminance changes that would occur), on the basis of predicted values, which are predetermined so as to compensate for the luminance changes that would occur. Moreover, the backlight is not turned on during the scanning period. As a result, flicker due to current leakage, etc., can be reduced or eliminated in a display device for which a scanning period and a scan stop period are set.

Abstract: A buffer circuit drives a capacitive load based on a voltage Vin. In a setup period, switches are in an ON state, and in a drive period, a switch is in an ON state. A voltage comparison unit compares the voltage Vin in the setup period and a voltage Vout in a drive period to output a comparison result voltage. A push-pull output unit includes a TFT for charge and a TFT for discharge. A drive control unit controls the TFTs to be in an OFF state in the setup period, and in the drive period, selectively controls the TFTs to be in an ON state in accordance with the comparison result voltage. If Vout<Vin, the comparison result voltage rises, the TFT becomes in an ON state, a voltage at a node falls, the TFT becomes in the ON state, and the voltage Vout rises. Thus, there is a provided a small-sized capacitive load drive circuit with low power consumption and robust against process variation.

Abstract: An image data management apparatus includes a unit adapted to display different types of plural frames (such as an in-focus frame and a face frame) at the same time in a manner capable of selectively changing both of those frames by a user operation such that an in-focus frame portion and a face frame portion can be easily confirmed.

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.
