Abstract

This paper reports an improved laser-addressed LCLV that employs scattering structure of smectic liquid crystal as display background. Its LC layer will not be easily electrically broken down. Full erasure can be achieved within 0.5 - 1 second. We also present a new method utilizing an insulative layer (inert insulative film) that is sandwiched between the LC layer and transparent electrode-absorbing layer. Such structure makes it possible to avoid decreasing LCLVs input sensitivity, which is caused by an increase of LC layer thickness, to improve bearing ability to high voltage and large current, and to achieve fast full erasure. Its highest breakdown voltage reaches 690 Vrms.
