Abstract:

A light shutter and an EL panel are sandwiched between two substrates, one of which includes a common front electrode. The common front electrode is electrically floating. Patterned rear electrodes, on either side of the EL panel, are capacitively coupled to each other by the common front electrode. The rear electrodes can be segmented and the segments addressed individually. Each substrate is coated with a layer of PDLC and the substrates are laminated by joining the layers of PDLC.
