Abstract
A flat-panel display (such as a liquid crystal display) includes one or more features that reduce temperature changes in an array of light valves disposed on a substrate. In particular, heat generated in a light source and/or electronics is conducted away from the light values. For example, a light-source holder, which contains the light source, may include holes that increase the thermal resistance between the light source and the substrate. Alternatively, the light-source holder may include a material having a thermal conductivity that is higher than that of stainless steel. In addition, the flat-panel display may include materials and/or a geometry that increases the thermal resistance along a direction in a plane of the substrate. By reducing temperature changes in the flat-panel display, these features can reduce or eliminate color changes and other visual artifacts that can degrade the quality of displayed images.
