    摘要： A signal line driving circuit includes a shift register having a plurality of shift circuits, each of which shifts a start pulse successively to the next stage, synchronizing with the timing of a clock signal. In this signal line driving circuit, shift pulses are outputted from an AND gate based on output pulses of two adjacent shift circuits. Meanwhile, a width specifying pulse for specifying a pulse width of the shift pulse is inputted via a transistor whose ON/OFF operation is controlled by the shift pulse. A logical operation circuit operates an AND of the shift pulse and the width specifying pulse and outputs the result of operation to a signal line. When the shift pulse is non-active, the transistor becomes OFF, which causes the signal line transmitting the width specifying pulse to be disconnected from the signal line driving circuit, thereby reducing a capacitive load of wiring. As a result, reduction of a parasitic capacitance of the wiring, reduction in the number of elements, reduction in the size of an amplitude of an input signal, etc. in the signal line driving circuit are attained.

    摘要： The scanning signal line driving circuit sequentially carries out active driving with respect to each set of a certain number of scanning signal lines which are adjacent to each other in a vertical direction, and when carrying out an actual writing with respect to a first set of a certain number of pixel lines adjacent to each other in the vertical direction, carries out pre-charging with respect to a second set of the certain number of pixel lines to which the actual writing is carried out next with a potential of a same polarity as that of the first set of the certain number of pixel lines. In this manner, it is possible to provide a matrix image display device with no irregularities in display quality and is capable of matching the apparent vertical resolution of the device to that of the image source, when using an image signal of vertical resolution lower than the maximum physical vertical resolution of the device.

    摘要： A precharge control circuit constituted by (1) a latch circuit mounted in a precharge circuit and (2) a level shifter circuit of a current drive type controlled through an output of the latch circuit is included. The precharge control circuit changes the latch circuit to an active state to cause the level shifter circuit of a current drive type to operate only during a precharge period and also during immediately preceding and succeeding periods, and outside these periods, changes the latch circuit in a non-active state and the level shifter circuit of a current drive type in an operating state to save power consumption in the level shifter circuit. This enables a low-power-consuming precharge circuit, as well as a low-power-consuming image display device with a high quality display capability, to be offered.

    摘要： A matrix type image display device has a structure in which the internal states of all of shift registers (the outputs of flip-flops included in the shift registers) in a scanning signal line drive circuit and data signal line drive circuit are made inactive by the use of an initializing signal generated by a NAND gate based on a combination of signals, which do not affect a displayed image, from a control circuit. With this structure, since the shift registers are initialized when power is supplied, it is possible to prevent an indefinite state when power is supplied. Therefore, by selectively inputting signals (such as clock signals) for controlling the shift registers, it is possible to prevent an excessive increase in the signal line load. Consequently, the operation of the image display device can be stabilized. Moreover, it is not necessary to improve the drive ability of an external IC incorporating the control circuit and the supply ability of a power supply circuit, thereby achieving a reduction in the cost and power consumption of the external IC.
