摘要： A driving circuit in a matrix type image display apparatus including a plurality of groups each including four standard unit circuits and one backup unit circuit. Each standard unit circuit includes disconnecting means for isolating the standard unit circuit from the driving circuit, and the backup unit circuit includes connecting means for connecting the backup unit circuit to an input signal line and an output signal line of any of the standard unit circuits within a group. The number of the backup unit circuits can be changed in accordance with a conforming ratio of each unit circuit, which makes it possible to eliminate idle backup unit circuits while maintaining a high overall conforming ratio of the driving circuit, thereby enhancing manufacturing efficiencies and reducing manufacturing costs.

摘要： A data signal output circuit is divided into a plurality of blocks, each having its own supply circuit. In each block, a plurality of shift register sections, constituting a shift register, output pulse signals which have been shifted according to clock signals. Driving sections sample a digital image signal in synchronism with the pulse signal, and output data signals corresponding to the image signal thus sampled to a plurality of output lines. Each supply circuit provided in the blocks receives the image signal when the image signal should be sampled by the driving sections, thereby supplying the image signal only to the minimum number of blocks to be operated. In this manner, the image signal is selectively supplied to the block so as to reduce the effective load on the image signal. As a result, the power consumption generated in the image signal lines can be reduced.

摘要： Picture elements and driving circuits for driving respective picture elements are monolithically formed on an insulating substrate. A protective circuit is provided for allowing input-output terminals of a driving circuit to conduct when a potential difference of not less than a predetermined value is generated. The protective circuit includes an MOS transistor, and a turn-on voltage thereof is set according to a thickness of a gate insulating layer. The protective circuit is formed on the insulating substrate simultaneously when forming the driving circuits. In this arrangement, because the turn-on voltage is set according to the thickness of the gate insulating layer and the thickness can be easily adjusted, an accurate turn-on voltage can be achieved. Since the arrangement prevents an increase in manufacturing cost, the driving circuits, etc., can be surely protected against static electricity generated in the manufacturing process and the input surge in the normal operation.

摘要： A delay detecting section detects the phase difference between a first detection signal as a reference and a second detection signal produced by delaying the first detection signal with part of a data signal line driving circuit itself or part of a circuit formed by the same process as the data signal line driving circuit. A phase adjusting section presumes an internal delay of the data signal line driving circuit, and adjusts the phase difference between a clock signal and start signal, and a video signal so that the data signal line driving circuit samples the video signal at an appropriate timing. These structures prevent a lowering of the image quality due to a difference in the timings of the video signal and sampling signal, and provide an image display device capable of displaying a good-quality image with a simple circuit structure.

摘要： An image display device includes an operational amplifier, a signal amplifier provided with a condenser for setting a gain of the operational amplifier, a signal amplifier circuit having such signal amplifier or a buffer amplifier, the signal amplifier circuit being provided with an offset adjusting function, and a data signal line drive circuit having a signal amplifier or a signal line drive circuit. The described arrangement enables the gain of the signal amplifier to be set by a capacitance of the condenser, thereby providing a signal amplifier circuit which permits the gain to be set much more precisely as compared to the conventional signal amplifier circuits even when adopting a signal amplifier formed on a semiconductor thin film such as a polycrystalline silicone thin film. The arrangement also provides a signal amplifier circuit which permits a voltage in the same level as a voltage of the input signal to be outputted. Furthermore, the arrangement provides high quality data signal line drive circuit and the image display device.
