摘要： A display device is provided which includes a luminescence element, a data line, and a switch connected between an electrode of the luminescence element and the data line. A voltage generation circuit supplies a pre-charge voltage to the data line. A current generation circuit supplies an inspection current to the electrode of the luminescence element plural times through the data line and the switch. A voltage detection circuit detects, the plural times, voltage values of the electrode supplied with the inspection current. When a difference between the voltage values is at least a predetermined value, the voltage generation circuit supplies the data line with an updated voltage that is higher than the pre-charge voltage.

摘要： A display device includes an organic EL element and a capacitor. A driving transistor is connected to an anode of the organic EL element and passes a current to the organic EL element. The current corresponds to a voltage held in the capacitor. A first switch is between the capacitor and a data line, and the data line supplies the voltage to the capacitor. A voltage detector is connected to the data line for detecting an anode voltage applied to the organic EL element. A second switch is between the anode and the data line. A controller turns on the first switch, causes the organic EL element to emit light, and causes the voltage detector to detect the anode voltage by turning off the first switch and turning on the second switch while the organic EL element is emitting light.

摘要： An image display device includes a luminescent panel in which luminescent pixels are two-dimensionally arranged. Each luminescent pixel has a stacked luminescent layer and driving layer. The driving layer includes a capacitive element that includes two electrode layers stacked in parallel. A memory stores coordinate information of a repaired luminescent pixel in which the capacitive element is repaired through disconnection of a part of one of the two electrode layers. A controller converts video signals received by the image display device into luminescent pixel signals that determine luminescence of the luminescent pixels. The controller outputs the luminescent pixel signals to a driver in a scanning order. The controller includes an incremental operator that increases one of the luminescent pixel signals that corresponds to the repaired luminescent pixel after reading only the coordinate information from the memory and comparing information of the video signals with the coordinate information in the scanning order.
