摘要： In an organic EL display, correction is made for a difference in screen luminance between the case of measuring characteristics of OLED elements, and the case of not measuring the characteristics of the OLED elements. A data line for feeding image data items, and a detection line for measuring the characteristics of the OLED elements are connected to respective pixels. Detection of the characteristics of the OLED elements is executed by utilizing a specified period of a frame period. Because an image-displaying period is limited in a frame where measurement of the characteristics of the OLED element 11 is executed, the luminance undergoes deterioration. In order to prevent the deterioration of the luminance, an analog-to-digital converter ADC causes γ characteristic of the OLED elements in the frame where measurement of the characteristics of 11 is executed to be varied by the agency of a signal from a timing controller Tcon to the analog-to-digital converter ADC, thereby increasing luminance intensity of light emission of the OLED elements.

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.
