    • 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.

A TFT (14) of one of the first and third pixel P1 and P3 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b). A TFT (14) of one of the second and fourth pixel P2 and P4 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b).

Owing to this, the load on the signal line driving circuit is reduced.

    • 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.
    • 每个像素包括具有不同亮度的第一和第二子像素。 每个子像素包括液晶电容器和存储电容器。 子像素(诸如任意像素的第一子像素和垂直相邻像素的第二子像素)的存储电容器对电极是电独立的。 通过每个存储电容器主干提供的存储电容器对电压具有在输入视频信号的一个垂直扫描周期(V-Total)内具有第一波形和第二周期(B)的第一周期(A),其具有第二波形,其中 V-Total = A + B。 第一波形在第一周期时间PA(其是整数倍)中的第一和第二电压电平之间振荡,并且至少两个等于一个水平扫描周期(H)。 定义第二波形,使得存储电容器对电压的有效值每隔预定数量(但是20个或更少)连续的垂直扫描周期具有预定的常数值。 因此,可以降低γ特性的视角依赖性。

    • 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
    • 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< H,TP / 4≦̸&bgr; 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。
