摘要： A data signal line drive circuit is provided with first sampling portions, and second sampling portions operated at a lower speed. By the action of selection circuits, the first sampling portions are operated during a normal display mode, and the second sampling portions are operated during a partial display mode. To ensure a correct sampling operation, one line time and a sampling interval are rendered longer during a display period of the partial display mode than during the normal display mode. During the normal display mode, both the first sampling portions and the second sampling portions may be operated. Thus, power consumption of a liquid crystal display device during the partial display is reduced.

摘要： A driver circuit for a display device includes a plurality of set-reset flip-flops and switch circuits, and is arranged so that a timing pulse for sampling outputted from the flip-flop is supplied to the switch circuit, so as to cause the switch circuit to receive a clock signal. The clock signal operates as a set signal of the next stage flip-flop and outputted as a control signal for carrying out pre-charging of a data signal line and a selected pixel connected to the data signal line, with a switch. Thus, in case of performing pre-charging of a signal supplying line with an internal pre-charging circuit by using a pre-charging power source having small driving ability, this arrangement can provide a driver circuit for a display device capable of preventing fluctuation of a signal supplied to a different signal supplying line, while keeping the circuit scale of the shift register small.

摘要： A shift register includes plural stages of flip-flops. The last-stage flip-flop Fn and the flip-flop Fn−1 that is the preceding flip-flop thereof are reset by inputting thereto an output signal from the last-stage flip-flop. A delaying means is provided, between an output terminal Q of the last-stage flip-flop for outputting the output signal and an input terminal R of the last-stage flip-flop for receiving the output signal, for delaying an input of the output signal to the input terminal R. The flip-flop Fn is reset at same time or after the preceding flip-flop Fn−1 is reset. With this arrangement, it is possible to prevent malfunctions of circuits due to a failure to reset the flip-flops.

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： An image display device of this invention includes a pre-charging voltage stabilizing section having current controlling means and charge holding means which respectively include a resistor and a capacitor to stabilize a pre-charging voltage. The charge holding means holds a voltage to be supplied to data signal lines, and the current controlling means suppresses a current flow from a control signal generating circuit, thereby suppressing power fluctuation at the control signal generating circuit. This suppresses fluctuation in the pre-charging voltage and enables data signal lines to be charged to a predetermined voltage, thereby suppressing deterioration of image quality and an increase in power consumption of the image display device. Further, when using the pre-charging voltage stabilizing section and setting a portion of a display as a video data non-display area avoiding display of video data in a non-match image display mode to display at fixed brightness in the video data non-display area by a pre-charging voltage from a pre-charging circuit, a control signal is suspended in a fixed period, thus realizing a non-match image display mode to display a video image of an aspect ratio different from that of a screen of a display without impairing an image quality, and saving power.

摘要： A driving device for a display apparatus having excellent contrast and a high display quality without crosstalk and display irregularities, and a driving method for the same are provided. In the driving device, scanning signals and data signals having a plurality of periodical inactive portions in one frame are applied to respective display dots. In the inactive term, a fixed voltage is applied to each of the display dots. The signal applied to the display dot is divided into small terms by the inactive portions, resulting in more high frequency components in a voltage signal applied to the display dot. As a result, the frequency components of a driving signal applied to the display dot are averaged. Further, a complete orthogonal function having 2.sup.r base function series is used, and a desired display data is completely reproduced on the display apparatus by an arithmetic process assuming auxiliary data in accordance with the number of the scanning electrodes.
