Abstract
An image display having a display panel including pixels in a matrix pattern, anodes formed corresponding to the pixels, a cathode in common with the anodes, EL elements provided between the anode and the cathode and including a light emitting layer, and TFTs for controlling the current supply to the EL elements. The display also has a scan driver for selecting pixel lines on the display panel, a data driver for applying RGB display signals corresponding to a pixel line of the display panel when the pixel line is selected, and a display controller for using a current value fed back by the common cathode and externally input RGB data to correct a white gray level of the RGB data and to generate RGB display data to the data driver.
