ABSTRACT:
Drive voltages corresponding to forward voltages for colors R, G, and B are supplied to display pixels for colors R, G, and B arranged on a display panel to correct disruption of a color balance due to aging and temperature dependence of EL elements. The maximum voltage among the drive voltages is detected, and a predetermined voltage is added to the maximum voltage by a charge pump or the like, so that an operation voltage of a level shifter in a gate driver is obtained. An operation signal having a level equal to that of the operation voltage is supplied to a gate of a transistor arranged in each pixel. Therefore, regardless of aging or the like, the control transistor accurately executes an ON operation at a timing for scanning to make it possible to prevent an image display from being defective.
