摘要： An example control signal generating circuit CTL for controlling the writing into pixels PIX instructs a data signal line drive circuit SD2, which is for driving pixels in a non-display area, to write a voltage VB or a voltage VW which are for non-displaying, not only in the first frame but also once in a predetermined number of frames. In other words, the pixels in the display area are refreshed at intervals longer than those in the case of refreshing the pixels in each frame. Thus, even if the mobility of an active element is high and the leak current on the occasion of OFF-state is large, or even if a large amount of electric charge is accumulated because of the photoelectric effect due to the use of a backlight, it is possible to prevent unnecessary displaying on the display area, which is caused because the writing into the pixels in the display area influences on the pixels in the non-display area, and hence it is possible to improve the quality of partial displaying, while restraining the power consumption.
摘要翻译：用于控制写入像素PIX的示例性控制信号发生电路CTL指示用于驱动非显示区域中的像素的数据信号线驱动电路SD2写入用于不显示的电压VB或电压VW ，不仅在第一帧中，而且在预定数量的帧中也是一次。换句话说，显示区域中的像素以比刷新每帧中的像素的情况更长的间隔更新。因此，即使有源元件的迁移率高，关断状态下的漏电流大，或者即使由于使用背光导致的光电效应而累积大量的电荷，可以防止由于对显示区域中的像素的写入而影响非显示区域中的像素而导致的显示区域的不必要的显示，因此可以提高部分显示的质量，同时限制功耗。

摘要： In an embodiment, a sampling signal to each data signal line is generated by using an output signal outputted from each flip-flop, and a precharge signal by which the data signal line to which the sampling signal is to be outputted is precharged is generated by using an output signal outputted from an output terminal of the flip-flop. Further, by providing a NOR circuit, an active period of the precharge signal and an active period of the sampling signal are prevented from overlapping each other. With this, in an embodiment of a display device driving circuit, including a precharge circuit, which causes a precharge power supply to precharge signal supply lines, the number of shift registers and the size of a circuit can be reduced.

摘要： A driver circuit for a display device includes NOR circuits on the input side of switches for controlling precharge of data signal lines and selected pixels connected to the data signal lines. While a video signal is written onto a data signal line, a signal instructing precharge of another data signal line is inputted from a shift register to the NOR circuits. A simultaneous precharge instruction signal is inputted from outside to the NOR circuits. According to this arrangement, precharge is performed in both a period in which a video signal is supplied to a data signal line and a period in which no video signal is supplied to any of the data signal lines. As a result, it is possible to perform precharge even with a precharge power source having relatively low driving capability, and to precharge the signal supply lines of the display device sufficiently.

摘要： A driver circuit of a display apparatus is provided with a nor circuit in each output line of a timing pulse. To the nor circuit, inputted are a timing pulse to be supplied to the output line and a pre-charge pulse for pre-charging a data signal line SL to which a write signal is being inputted based on the timing pulse. With this structure, it is possible to realize a driver circuit storing a pre-charge circuit of a display apparatus, which can surely prevent a collision between a pre-charge potential and a potential of a video signal in a signal supply line when pre-charging the signal supply line from a pre-charge power supply of a small driving performance, while maintaining the number of stages in the shift register to be the required minimum number.

摘要： In each horizontal period, by switching ON switches respectively provided for three data signal lines for R, G and B in a group at the same time only in a predetermined period, the data signal lines in the group are preliminary charged to a predetermined potential at the same time before a data signal supply period. In a subsequent data signal supply period, respective switches of data signal lines for R, G and B are switched ON sequentially, to sequentially supply respective data for R, G and B to pixels on a scanning signal line as selected are supplied via data signal lines. As a result, in a display device driven by time-division based on a group of sequentially provided data signal lines, it is possible to suppress up-throw potential fluctuations when display.
