Pixels that emit red lights, pixels that emit green lights, and pixels that emit blue lights are arranged on a screen in a matrix manner. A detection system is provided on the upper side of the screen. A detection line extending from the detection system is coupled to the respective pixels through analog switches and digital switches controlled by switch controlling lines. A detection scanning circuit is provided on the right side of the screen. Detection switch controlling lines extend from the detection scanning circuit. By appropriately selecting the analog switches, the switch controlling lines, and the detection switch controlling lines, the voltage-current characteristics of plural pixels are measured at the same time.

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： Provided is an image display device in which deterioration of a self-light-emitting element within a pixel is corrected accurately. A detection unit detects, within a detection period, a difference in characteristics between self-light-emitting elements of adjacent pixels. A first subtraction circuit outputs a differential voltage between a reference voltage and an image voltage to a self-light-emitting element that is determined by the detection unit as a deteriorated element. An amplifier amplifies an output of the first subtraction circuit with a gain [1/{1-(α/100)}]1/2 when a driver transistor is driven in a saturation region. The amplifier amplifies the output of the first subtraction circuit with a gain [1/{1-(α/100)}] when the driver transistor is driven in a linear region. A differential between the reference voltage and an output of the amplifier obtained by a second subtraction circuit is used as a corrected image voltage.
