    摘要： An image display apparatus includes a plurality of scanning wires in an image display region for transmitting a scanning signal, a plurality of signal wires intersecting the plurality of scanning wires in the image display region for transmitting a signal voltage, a plurality of current driven electroooptical display elements each arranged in a pixel region surrounded by the wires connected to a common power supply, a plurality of driving elements in the pixel region connected with the electro-optical display elements and a plurality of memory control circuits for holding the signal voltage in response to the scanning signal to control driving of the driving elements based on the held signal voltage. The memory control circuit samples and holds the signal voltage while blocking a bias voltage from being applied to the driving elements, and subsequently applies the driving elements with the held signal voltage as the bias voltage.

    摘要： As each of sampling switch elements turns on in response to a scanning signal, a signal voltage from a signal wire is held on and written into a sampling capacitor. At this time, the signal voltage is held on the sampling capacitor on the basis of a common electrode. As the scanning signal transitions from high level to low level, each of the sampling switch elements turns off and changes into a floating state in which the sampling capacitor is electrically insulated from the signal wire and a driving TFT. As the scanning signal changes from high level to low level, each of the driving switches becomes conductive so that the signal voltage held on the sampling capacitor is applied as it is between the source and gate of the driving TFT as a bias voltage to make the driving TFT conductive, causing an organic LED to emit light.

    摘要： A self-emission type display device is disclosed. A current comparator circuit (47) in a data line drive circuit having a current compensating function (2) detects only the result of size comparison between the current amount due to the degeneration of a self-emission element and a reference value. The reduction of the current amount below the reference value is stored by being added to the least significant bits of a display data storage circuit (30). In accordance with the display data read from the storage circuit (30), a D/A conversion circuit (41) generates a write signal voltage.
