    摘要: An image display apparatus can be arranged so that a picture element capacity obtains a value provides display data retention of less than 99% by writing same data to a picture element a plurality of times during 1 frame period. This makes it possible to disuse the auxiliary capacity and to improve an aperture ratio. Moreover, with the present invention, an MOS transistor arranged in each picture element as a switching element for driving the picture element, a scan signal line driving circuit and a data signal line driving circuit for transmitting a driving signal based upon display data to the MOS transistor through a data signal line and a scan signal line, and a first frame memory and a second frame memory provided outside the picture element for storing display data to be outputted to a data signal line driving circuit for 1 frame are formed on one substrate. As a result, it is possible to improve package efficiency and lower cost by using a driver monolithic technique.

    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.

    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: A voltage output circuit has decoders, a selecting circuit, a logical circuit and an output circuit in order to select one of plural gradation power source lines for a prescribed period based upon k bits and m bits of an n-bit digital signal. The k bits of the digital signal are converting into 2.sup.k decoded signals by one decoder, and another m bits are converted into 2.sup.m decoded signals by the other decoder. The selecting circuit generates a signal for selecting one of periods which were obtained by dividing one horizontal scanning period into 2.sup.k based upon k-numbered timing signals by using the 2.sup.k decoded signals. The logical circuit generates 2.sup.n signals composed of combinations of the signals from the selecting circuit and the 2.sup.m decoded signals. Moreover, one of the 2.sup.m gradation power source lines is selected by an output switch by using the signal from the logical circuit. As a result, in an image display device using a digital signal as an input video signal, a number of gradation power source lines is reduced and the arrangement of driving circuits is simplified without deteriorating display quality. As a result, a cost of the image display device can be lowered.

    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.
