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 capacitance is provided having a first node connected to an input terminal of the control circuit. A display signal voltage generation circuit generates display signal voltages for the pixels, while a pixel drive voltage generation circuit generates pixel drive voltages for the pixels. In addition, a connecter is provided for connecting either one of the display signal voltages or the pixel drive voltages to a second node of the capacitance.
