1. An image display device, comprising:
a luminescent panel in which luminescent pixels are two-dimensionally arranged, each of the luminescent pixels having a stacked structure of at least a luminescent layer and a driving layer, the driving layer including a capacitive element for driving the luminescent layer, the capacitive element including two electrode layers stacked in parallel; a memory that stores coordinate information of a previously repaired luminescent pixel of the luminescent pixels, the capacitive element of the repaired luminescent pixel having been repaired through disconnection of a part of one of the two electrode layers included in the capacitive element; and a controller that converts video signals received by the image display device into luminescent pixel signals that determine luminescence of the luminescent pixels, and that outputs the luminescent pixel signals to a signal line driver in a scanning order, wherein the controller includes an incremental operator that increases and outputs one of the luminescent pixel signals that is associated with the previously 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, the signal line driver outputs the increased one of the luminescent pixel signals to the previously repaired luminescent pixel and outputs unchanged luminescent pixel signals to normal luminescent pixels that have not been previously repaired, the one of the two electrode layers is planarly divided into electrode block layers, and when the two electrode layers are conductive, disconnection of one of the electrode block layers reduces a capacitance of the capacitive element from a designed value at a predetermined rate, the electrode block layers are connected through at least one conductive line, the electrode block layers and the at least one conductive line being coplanar, an other of the two electrode layers is a plate that defines at least one void, each of the at least one void corresponding to one of the at least one conductive line, and the previously repaired luminescent pixel is identified as having a short-circuited capacitive element, an abnormal electrode block layer of the short-circuited capacitive element is identified, the luminescent pixel being repaired by being irradiated with a laser to electrically insulate the abnormal electrode block layer of the capacitive element from other electrode block layers of the capacitive element. |
