Patent ID: 7671835

Claim:
An image display apparatus which, on the basis of image data, applies a prescribed image display voltage between a pair of electrodes at least one of which is a transparent electrode, thereby moving particles consisting of both positively charged black particles and negatively charged white particles enclosed between the electrodes to carry out image display by the particles arranged on the transparent electrode side, the apparatus comprising: a recovery section which recovers a reduction in quantity of charge of the particles; a detection section which detects quantity of charge of the particles; and a control section which compares the detected quantity of charge with a prescribed reference quantity, causes the recovery section to initiate or to continue the recovery for a prescribed period of recovery time if the detected quantity of charge is less than the prescribed reference quantity, and causes the recovery section to terminate the recovery if, after a prescribed period of recovery time passes, the detected quantity of charge exceeds the prescribed reference quantity.
