    摘要： An image display device includes pixel circuits, a power supply line, and a data line for supplying a data signal to the pixel circuits. The pixel circuits each include a light emitting element, a drive transistor for controlling light emission of the light emitting element, a storage capacitor provided between the data line and a gate electrode of the drive transistor, a both-end connection switch for connecting both ends of the storage capacitor to each other, and a current interruption switch for interrupting a path of a current flowing from the power supply line through the both-end connection switch. Before the data signal is supplied to each of the pixel circuits, the both-end connection switch connects the both ends of the storage capacitor to each other, and the current interruption switch is disconnected.

    摘要： A display device is provided which displays images by emitting light when a reference voltage is applied to pixels. An average picture level calculation unit of a reference voltage calculation unit in a rectangular wave driving unit of a TFT substrate calculates the value of average picture level, and a ΔV calculation unit of a reference voltage calculation unit calculates a correction amount ΔV of the reference voltage based on the average picture level value. The calculated correction amount ΔV is added to a reference voltage and is used as the voltage of a rectangular wave signal that is output to each pixel from a rectangular wave driving unit. In each pixel in which a data signal corresponding to the grayscale value is stored, an organic EL device emits light in accordance with the rectangular wave signal.

    摘要： A plurality of organic EL elements which are arranged on a display panel lowers the brightness along with a lapse of light emitting time and hence, the power consumption is increased to maintain the brightness. However, the increase of the power consumption shortens a lifetime of the organic EL elements. To overcome this drawback, a power supply circuit which drives the display panel has a function of controlling an electric power supplied to the display panel to a fixed value or less in response to a detection signal from a detection part which detects a cathode current of the organic EL elements.

    摘要： An image display is provided with a display area including pixels, each including illuminating means. A control circuit turns the illuminating means of the pixels on and off. A first terminal of a capacitor is connected to an input terminal of the control circuit. An image signal voltage generation circuit generates image signal voltages and a pixel drive voltage generation circuit generates pixel drive voltages for the pixels. A connector is provided for connecting either one of the image signal voltages or the pixel drive voltages to a second terminal of the capacitor. As such, an amount of drive current for the pixels is controlled in accordance with both the pixel drive voltage and the image signal voltage.
