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.
摘要翻译：在本发明的一个实施例中，公开了一种液晶显示装置，其中栅极驱动器施加栅极导通脉冲，使得第二周期比第一周期长。第一期和第二期定义如下。在数据信号极性反转之前施加的栅极导通脉冲中，最接近极性反转时刻的栅极导通脉冲的最后一端早于栅极导通的水平周期的结束时间脉冲被施加。第一个周期从栅极导通脉冲的最后一个开始，并在施加栅极导通脉冲的水平周期的结束时间结束。第二周期从极性反转开始，在极性反转后施加的栅极导通脉冲之间的最接近极性反转的时刻的栅极导通脉冲的施加开始时刻结束。因此，即使当极性反转时数据信号波形不尖锐时，也可以抑制显示不均匀并进行高质量的显示。

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.
