Abstract
An image display is provided with a display area including pixels, each including illuminating means. A control circuit turns the illuminating means of the pixels on and off. A first terminal of a capacitor is connected to an input terminal of the control circuit. An image signal voltage generation circuit generates image signal voltages and a pixel drive voltage generation circuit generates pixel drive voltages for the pixels. A connector is provided for connecting either one of the image signal voltages or the pixel drive voltages to a second terminal of the capacitor. As such, an amount of drive current for the pixels is controlled in accordance with both the pixel drive voltage and the image signal voltage.
