ITO HEATER

摘要

PURPOSE: An ITO heater is provided to reduce expenses and easily perform temperature control by locating the heater to the surface of an LCD. CONSTITUTION: An ITO(Indium Tin Oxide) heater for a liquid crystal display, typically a DSTN(Double Super Twisted Nematic) display comprises an active liquid crystal cell(12) for optical modulation, characterized by a dummy cell(11) adapted for optical compensation comprising two substrates(13) with liquid crystal(14) and characterized by a heater(1). The heater comprises a transparent conductive layer applied to one of the substrates, and the dummy cell further comprises electrically a conductive spacing unit(15) for simultaneously maintaining a desired cell gap and equalizing the electrical potential between the two substrates(13).
