ABSTRACT:
There is provided an image display apparatus having: display devices; a spacer; and a drive circuit. The drive circuit has a first correction circuit that corrects inputted data to make it linear with luminance and a second correction circuit. The second correction circuit has a calculation circuit for calculating an evaluation value and an adjustment circuit. The evaluation value relates to suppression effect that the spacer suppresses an influence on the light emission of a predetermined emitting region due to the inputted image data by driving non-corresponding display devices and is calculated by using the electric charge signal after converting a luminance signal into an electric charge signal. The adjustment circuit calculates an adjustment value that refers to a property of a phosphor based on the luminance signal and dynamically calculates the correction value by using the evaluation value and the adjustment value.
