Abstract
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.
