摘要： Provided are a display device that can suppress occurrence of a color breakup as well as occurrence of a false contour, and a control method therefor. In the display device, a plurality of sub-frame periods forming one frame period are divided into: a first group to which sub-frame periods with the same length of light transmission periods belong; and a second group to which sub-frame periods with lengths of light transmission periods shorter than those of the sub-frame periods in the first group and different from each other belong. Further, among the sub-frame periods that belong to the first group, sub-frame periods having the light transmission period increase in number from a middle of the one frame period toward a start point and an end point of the one frame period in accordance with an increase of the gray level.

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： 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.
