摘要： In one embodiment of the present invention, the image display period of the first sub frame of an N-th frame is arranged to partly overlap the image display period of the second sub frame of the N-th frame and the image display period of the second sub frame of the (N−1)-th frame. Also, in each sub frame, a period in which grayscale display voltages are written into all horizontal lines of the display screen is arranged to be identical with the image signal input period of one frame of an input image signal. In addition, the grayscale display voltages with which pixels that are horizontally or vertically neighbored are charged are arranged to have inverse polarities, and the polarity of the grayscale display voltage charging each pixel is reversed in each frame. Furthermore, a short circuit period is provided and in this period neighboring data signal lines are short-circuited each time the polarity of the grayscale display voltage output to each data signal line is reversed. With this, in a display apparatus performing sub frame display, a time lag between the input of an image signal and image display is reduced, the cost of the frame memory is reduced, and the power consumption for AC driving is reduced.
摘要翻译：在本发明的一个实施例中，第N帧的第一子帧的图像显示周期被布置成部分地与第N帧的第二子帧的图像显示周期和第N帧的图像显示周期重叠（N-1）帧的第二子帧。此外，在每个子帧中，将灰度显示电压写入显示屏的所有水平行的时段被布置为与输入图像信号的一帧的图像信号输入周期相同。此外，将水平或垂直相邻的像素充电的灰度显示电压设置为具有反极性，并且在每个帧中对每个像素充电的灰度显示电压的极性反转。此外，提供短路周期，并且在该周期中，每当输出到每个数据信号线的灰度显示电压的极性反转时，相邻的数据信号线被短路。由此，在执行子帧显示的显示装置中，图像信号的输入与图像显示之间的时滞减少，帧存储器的成本降低，并且AC驱动的功耗降低。
