摘要： An image display device includes signal lines; a video signal generating means which generates a video signal based on gray level information from the outside; a compensation signal generating means which generates a compensation signal based on the gray level information; a selecting means which alternately supplies the video signal and the compensation signal to the signal lines; and a plurality of pixel circuits which are connected to the signal lines. The compensation signal generating means generates the compensation signal based on the gray level information such that the larger the time integration of the potential of the video signal is, the smaller the time integration of the potential of the compensation signal is.

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 apparatus includes data lines, scanning lines arranged to cross the data lines, and pixel circuits aligning along the data lines and the scanning lines, such that one of the pixel circuits corresponds to each intersection between the data lines and the scanning lines. In addition, image signal lines transmit image signals, and switches connect the data lines to the image signal lines so that each of the data lines is connected to one of the image signal lines. The data lines are arranged such that adjacent data lines form a pair of data lines, and adjacent pairs of data lines are spaced apart from each other by two columns of pixel-circuits. Respective data lines of the pair of data lines are connected by the switches to two different image signal lines, and the switches connecting the pair of data lines to corresponding image signal lines are activated simultaneously.
