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： In one embodiment of the present invention, a liquid crystal panel driving apparatus is disclosed which sequentially receives pieces of video data for one data signal line, (i) prepares a data string by sorting, in order of outputting, a plurality of pieces of video data inputted in a predetermined period while adding a piece of dummy data to a predetermined position, (ii) assigns one horizontal scanning period to an output of a piece of video data while assigning a dummy scanning period to an output of a piece of dummy data, and (iii) sets one horizontal scanning period shorter than an interval of inputting of pieces of video data.

摘要： In one embodiment of the present invention, each pixel includes first and second subpixels. CS bus lines connected to the respective storage capacitors of the first and second subpixels are electrically independent of each other. A CS voltage has a waveform that inverts its polarity at least once a frame, which includes a first subframe for sequentially scanning a series of odd rows and a second SF for sequentially scanning even rows that have been skipped during the first SF. A source signal voltage varies so as to have two frames or subframes with mutually opposite polarities. A CS voltage has a waveform that has quite opposite consequences on the effective voltage of a subpixel of a pixel connected to the jth scan line to be selected during the first subframe and on that of another subpixel of a pixel connected to the (j+1)th scan line to be selected during the second subframe. In this manner, the deterioration in display quality, which would be caused if either a source line inversion drive or a block inversion drive is applied to a multi-pixel technology, can be minimized.

摘要： Each pixel includes first and second subpixels and two switching elements provided for those subpixels. Each subpixel includes a liquid crystal capacitor and a storage capacitor. The storage capacitor counter electrodes of the first and second subpixels are electrically independent. A storage capacitor counter voltage applied to each storage capacitor counter electrode by way of its associated storage capacitor line has a first period (A) with a first waveform during one vertical scanning period. The first waveform oscillates between multiple voltage levels in a first cycle time (PA) that is an integral number of times (and at least four times) as long as one horizontal scanning period (H). Each of the voltage levels has a flat portion with a duration TP. While the two switching elements are ON, a display signal voltage is applied to the respective subpixel electrodes and respective storage capacitor electrodes of the first and second subpixels. After the two switching elements have been turned OFF, voltages at the storage capacitor counter electrodes of the first and second subpixels change. And if an interval between a point in time when the two switching elements in ON state have just been turned OFF and a point in time when the storage capacitor counter voltage changes for the first time is βH, TP/4≦β

摘要翻译： 每个像素包括为这些子像素提供的第一和第二子像素和两个开关元件。 每个子像素包括液晶电容器和存储电容器。 第一和第二子像素的存储电容器对电极是电独立的。 通过其相关联的辅助电容线施加到每个存储电容器对电极的存储电容器对电压在一个垂直扫描周期期间具有第一周期（A），其具有第一波形。 第一波形在第一周期时间（PA）中的多个电压电平之间振荡，其长度为一个水平扫描周期（H）的整数倍（至少四次）。 每个电压电平具有持续时间TP的平坦部分。 当两个开关元件为ON时，对第一和第二子像素的各个子像素电极和各个存储电容器电极施加显示信号电压。 在两个开关元件已经断开之后，第一和第二子像素的存储电容器对电极处的电压改变。 并且如果两个开关元件处于导通状态的时间点之间的间隔刚刚被关断，并且存储电容器对电压首次变化的时间点为βH，则TP / 4 <=β<3。 TP / 4满足。 因此，即使呈现静止图像，子像素之间的亮度差也不容易作为不均匀，从而获得良好的显示质量。
