Patent ID: 6876345

Claim:
An image display having a display area made up of a plurality of pixels and a signal line for feeding a display signal voltage to the pixels, the image display comprising: a first switch means for inputting the display signal voltage from the signal line to one end of a first capacitance; an input voltage inversion/output means connected at its input terminal to the other end of the first capacitance; an illuminating means controlled by an output of the input voltage inversion/output means; a second switch means provided between the input terminal and an output terminal of the input voltage inversion/output means, wherein the first switch means, the input voltage inversion/output means, the illuminating means and the second switch means are provided in at least one of the plurality of pixels; a pixel drive voltage generation means for generating a pixel drive voltage, the pixel drive voltage being swept within a predetermined voltage range including the display signal voltage; and a pixel drive voltage input means for inputting the pixel drive voltage to the one end of the first capacitance in the pixel.
