  • Publication number: 20180108309
    Abstract: Each driving circuit in a shift register includes an output unit, a precharge unit, a boosting unit, a gate voltage discharge unit, a gate line discharge unit, and an internal line netA. The output unit includes a TFT(F) that outputs a selection voltage to a gate line. The precharge unit includes a TFT(B) that outputs a control voltage for causing the TFT in the output unit to operate. The boosting unit boosts up a gate voltage of the TFT in the output unit through a capacitor (Cbst). The gate voltage discharge unit includes a TFT(K) that pulls down this gate voltage during a non-selection period while the gate line is not selected. The gate line discharge unit includes a TFT(L) that outputs a non-selection voltage to the gate line during the non-selection period while the gate line is not selected. The internal line is connected to a gate terminal of the TFT in the output unit, the precharge unit, the gate voltage discharge unit, and the boosting unit.

  • Patent number: 9581843
    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.

  • Patent number: 9520097
    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.
