Patent ID: 8477086

Claim:
A display device, comprising: a display region having a plurality of pixels formed in a matrix fashion, each pixel having an OLED element; and wherein the display device is configured to display an image a first frame in the display region in a first frame period during which detection of characteristics of the OLED elements is executed and an image of a second frame in the display region in a second frame period during which detection of characteristics of the OLED elements is not executed; the first frame period having a first display period during which the image of the first frame is displayed in the display region and a detection period during which detection of characteristics of the OLED elements is executed by detecting voltages across terminals of the OLED elements when a constant current is supplied to the OLED elements; and the second frame period having a second display period during which the image of the second frame is displayed in the display region and not having a detection period, the second display period being longer than the first display period; a length of the first frame period is equal to a length of the second frame period, and detection of the characteristics of the OLED elements during the detection period is executed in a blanking period of the first frame period during which light is not emitted by the OLED elements that occurs immediately prior to writing of an image for a next frame after the first frame to the OLED elements.
