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. This makes it possible to suppress an increase in vertical display period even though a piece of dummy data is added to inputted video data while a dummy scanning period is assigned thereto.

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： The vertical scan period of the input video signal is divided into at least two sub-frames. In each of the sub-frames, a display signal voltage is written into each pixel. Two vertical scan periods in which the input video signals are continuous contain a sequence of two continuous sub-frames where a display signal voltage is written with the same polarity and a sub-frame where the polarity of the display signal voltage is inversed. The auxiliary capacity opposing voltage includes, in each of the sub-frames, a first waveform vibrating with a first cycle of the horizontal scan period multiplied by an integer not smaller than 2 and a second waveform in which an effective value of the auxiliary capacity opposing voltage is set to a predetermined constant value for each vertical scan period of a predetermined number of continuous input video signals.

In a liquid crystal display device employing both a 2-line dot-inversion drive method and a charge-sharing method, a second charge-sharing period (TB), which is a charge-sharing period 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 first charge-sharing period (TA), which is a charge-sharing period 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.

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.
