The direct-view matrix-addressed smectic a LCD panel: Dynamic behavior

Abstract

We present an analytical solution of the heat-flow equation applied to a direct-view thermally matrix-addressed smectic LCD panel. Using experimental values of the operating parameters of an actual panel, we compute the corresponding temperature profiles in the liquid-crystal layer. These theoretical results are compared with temperature measurements on a test cell to verify the model. Finally, we show how the thermal analysis can improve the understanding of the behavior of the smectic display, and thus to optimize the cell design for the widest possible operating margin.
