Thin-film EL image display panel with power saving features

摘要

A thin-film EL display panel has a plurality of scanning side electrodes and a plurality of data side electrodes. The thin-film EL display panel is excited to emit light through a pre-charge mode, a discharge modulation mode and a write mode. A voltage lower than a modulation voltage is supplied from the data side electrodes to the thin-film EL display panel as a first pre-charge voltage. Thereafter, a difference voltage between the first pre-charge voltage and the modulation voltage is supplied from the scanning side electrodes to the panel as a second pre-charge voltage, thus reducing power consumption to a minimum during the pre-charge mode.
