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.

摘要： In an image display device, each pixel includes a drive transistor for driving a light emitting element, a capacitive element which is connected between a signal line and a control electrode of the drive transistor, and a reset switching element. The reset switching elements of all pixels are turned off within a light emission period, and a PWM signal is supplied to a signal line from a drive circuit. A cycle of the PWM signal in a low brightness display mode is shorter than a cycle of the PWM signal in a standard brightness display mode. Due to such a constitution, the constitution of a drive circuit can be simplified, and it is possible to control light emission brightnesses of respective pixels of red, green and blue over a wide range from high brightness to low brightness while taking a balance among the light emission brightnesses.
