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.
