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： Each pixel includes first and second subpixels with different luminances. Each subpixel includes a liquid crystal capacitor and a storage capacitor. The storage capacitor counter electrodes of the subpixels (such as those of the first subpixel of an arbitrary pixel and the second subpixel of a vertically adjacent pixel) are electrically independent. A storage capacitor counter voltage supplied through each storage capacitor trunk has a first period (A) with a first waveform and a second period (B) with a second waveform within one vertical scanning period (V-Total) of an input video signal, where V-Total=A+B. The first waveform oscillates between first and second voltage levels in a first cycle time PA, which is an integral number of times, and at least twice, as long as one horizontal scanning period (H). The second waveform is defined such that the effective value of the storage capacitor counter voltage has a predetermined constant value every predetermined number of (but 20 or less) consecutive vertical scanning periods. Thus, the viewing angle dependence of the γ characteristic can be reduced.

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 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.
