Abstract
A liquid crystal display device (11) is made by sputtering a layer of indium-tin oxide and copper on a transparent substrate. This metal layer is photodelineated to form a pattern of electrodes (17) and heating elements (81), the heating elements being interlaced between the electrodes. The heating elements are converted to a more resistive form by applying a constant voltage signal to only the heating elements in an oxygen-containing atmosphere. The assembled LCD has the heating elements on the inside of the display, so that when the heating elements are pulsed, they heat only a portion of the liquid crystal fluid in the immediate proximity. The heaters are activated by a signal from a display driver.
