US 6,606,132 B2 · Vibration and shock resistant liquid crystal display and associated method

Abstract

A liquid crystal display (LCD) includes a first panel assembly and a second panel assembly with a liquid crystal material layer therebetween. The first panel assembly has a resonant frequency substantially the same as the second panel assembly's. The first panel assembly has substantially matched mechanical properties to the second panel assembly. Each of the assemblies may include a support panel, such as provided by a glass plate. A front assembly, may also include at least one filter panel. The LCD may also include a frame mounted around a periphery of the first and second panel assemblies. The first panel assembly has a coefficient of thermal expansion substantially the same as a coefficient of thermal expansion of the second panel assembly. The frame also has a coefficient of thermal expansion substantially the same as the coefficient of thermal expansion of the first and second panel assemblies.
