摘要： The voltage-current property of the specific pixel is measured to store the data on a single line in a line memory. The property data of adjacent pixels are compared. A failure determination unit detects whether or not the pixel to be compared is faulty. If it is determined as being faulty, the faulty pixel is removed from the pixel group to be compared. The burn-in determination unit performs the comparison using normal pixels only to provide the correct burn-in data. The calculation unit reflects the burn-in data in the image data from the host.

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.
