Image display device, control method for an image display device, and adjustment system for an image display device

Abstract

It is aimed to provide a technology capable of stabilizing light-emitting luminance of an image display device. In order to achieve the above-mentioned object, an image display device includes a pixel circuit including a light-emitting element, a recognizing portion which recognizes a predicted value of a parameter on driving of the pixel circuit based on image data, and an obtaining portion which obtains an actually-measured value of the parameter while causing the light-emitting element to emit light in accordance with the image data. This image display device further includes a comparing portion which compares the predicted value and the actually-measured value with each other, and a control portion which controls a power supply voltage applied to the pixel circuit in accordance with a comparison result of the comparing portion. The control portion increases/decreases, in response to a fact that the actually-measured value falls outside a first reference range with the predicted value being as a reference, the power supply voltage so that the actually-measured value is included in a second reference range which is within the first reference range and is narrower than the first reference range, and stops the increase/decrease of the power supply voltage in a case where a relationship in which the actually-measured value is included in the second reference range is satisfied. Note that the control portion may be provided outside the image display device.
