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 device includes a black spot defect position determination circuit which determines a position of a black-spot defective pixel of a self-luminous display panel. A detection-use current source in the black spot defect position determination circuit is connected to pixels during a period separate from a display period of data signals thus determining a black spot defect. The position of the black spot defect is stored in a storing circuit and is transmitted to a display and detection control circuit. The display and detection control circuit corrects the data signals to the pixels around the defective pixel based on a black spot defect position, and drives a data line drive circuit based on the corrected data signals thus visually correcting the black spot defect.

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.
