    摘要: In one embodiment of the present invention, a gate driver creates a dummy insertion period in which the driver does not apply a gate on pulse to a scanning signal line immediately after the time of the inversion of a data signal. When a period from the time of the application of the gate on pulse to an odd numbered or even numbered scanning signal line to which the gate on pulse is applied previously to the time of the application of the gate on pulse to an even numbered or odd numbered scanning signal line to which the gate on pulse is applied later is set as an adjacent line writing time lag period for two scanning signal lines adjacent to each other, a CS control circuit allows the polarity of every CS signal to be reversed on the same cycle at least in the adjacent line writing time lag period. This makes it possible to provide a liquid crystal display device capable of offering high quality display in which unevenness in the display is suppressed without being affected by the blunt waveform of the data signal and the blunt waveform of a retention volume signal at the time of the inversion.

    摘要: In a liquid crystal display device according to one embodiment of the present invention, when the polarities of the source signal voltages do not change over a plurality of horizontal scanning periods, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the jth row rises before the source signal voltages change to values that correspond to pixels along the jth row. Next, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the jth row falls, and then the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the kth row (j≠k) rises. The polarities of the storage capacitor signal voltages applied to storage capacitor bus lines that correspond to sub-pixels of pixels along the jth row are inverted after the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the kth row rises.

    摘要: An active matrix type liquid crystal display device may include a black signal insertion device to apply a voltage corresponding to a black display as a voltage for data signal lines only during a black signal insertion period that is a part of one frame period, a black insertion ratio change device to change the insertion period, and an unchanged-storage-capacitor-phase-keeping device to control the insertion period after the change. The control makes a time difference the same, before and after the change, between (i) a timing, among timings at which signal voltages of the first or second storage capacitor line rise, at which a storage capacitor voltage rises that is both prior to a start timing of the insertion period and a closest timing to the start timing of the insertion period, and (ii) the start timing of the insertion period.

    摘要: In one embodiment of the present invention, a liquid crystal display device is disclosed in which a gate driver applies a gate-on pulse so that a second period is longer than a first period. The first period and the second period are defined as follows. Among gate-on pulses applied before the moment of polarity inversion of a data signal, the last end of the gate-on pulse nearest to the moment of the polarity inversion is earlier than the end time of the horizontal period during which the gate-on pulse is applied. The first period starts at the last end of the gate-on pulse and ends at the end time of the horizontal period during which the gate-on pulse is applied. The second period starts at the moment of the polarity inversion and ends at the moment of the application start of the gate-on pulse nearest to the moment of the polarity inversion among the gate-on pulses applied after the polarity inversion. Thus, even when a data signal waveform is not sharp upon polarity inversion, it is possible to suppress display unevenness and perform a high-quality display.

    摘要: A voltage corresponding to a black display is applied in a part of one frame period. When a black signal insertion period is changed, the black signal insertion period after the change is controlled so that (i) a time from a position at which a signal voltage of a first or second storage capacitor line rises to a position at which a first black insertion pulse rises in the black signal insertion period before the change becomes equal to (ii) a time from a position at which a signal voltage of the first or second storage capacitor line rises to a position at which a first black insertion pulse rises in the black signal insertion period after the change. This makes it possible to provide an active matrix type liquid crystal display device capable of preventing the occurrence of a difference in luminance between an upper side of a display panel screen and a lower side of the display panel screen in a case where black insertion is carried out with respect to a display panel which forms bright and dark sub-pixels by changing, for every sub-pixel, an effective voltage to each pixel by capacitive coupling of a storage capacitor and a liquid crystal capacitor, and a drive method of the active matrix type liquid crystal display device.

    摘要: Provided are a display device which may be capable of eliminating display irregularities due to the difference in the charging rate between lines, while preventing increase in heat generation and power consumption by the device, and a circuit and method for driving the same. In a liquid crystal display device employing both a 2-line dot-inversion drive method and a charge-sharing method, a charge-sharing period (TB) within a horizontal scanning period (2H period) in which the polarity of each data signal is the same as that in one horizontal scanning period previous thereto, is set to be longer than a charge-sharing period (TA) within a horizontal scanning period (1H period) in which the polarity of each data signal is different from that in one horizontal scanning period previous thereto. Thus, a charge period within the 2H period can be shorter than that within the 1H period.
