Abstract

A light shutter includes a first electrode, a second electrode, and a third electrode, wherein the first and second electrodes are capacitively coupled to each other by the third electrode. The first electrode and the second electrode can be segmented and the segments separately addressed. In a display having a light shutter and an EL panel stacked on the same side of a substrate, there is a common front electrode and separate rear electrodes for operating the light shutter and the EL panel. The common electrode is electrically floating and the rear electrodes are capacitively coupled to each other by the common front electrode. The rear electrodes can be segmented and the segments separately addressed.
