Abstract: A temperature sensor for the liquid crystal portion of a liquid crystal display assembly which includes a thin layer of transparent conductive material which is spread across the viewing area of the display. This layer of transparent conductive material can provide heat to warm up the display when a large voltage is put across it, and can also be used to measure liquid crystal temperature. It is known that the resistance of materials such as indium tin oxide (ITO) changes at a known rate with respect to temperature. By using this transparent layer of material in the stacked elements of a liquid crystal display assembly, an accurate reading of the liquid crystal temperature can be made.
