DEFROSTING OF AUTOMOBILE WINDSHIELDS USING HIGH LIGHT TRANSMITTING ELECTROCONDUCTING FILMS
The development of a new high light transmitting electroconducting film for defrosting of car windshields is described. The film, called Hyviz, is deposited on glass by vacuum sputtering and consists of a complex of indium oxide and tin metal. This paper considers the electrical design of windshields, having films with electrical resistance and supply voltages between 30 and 80 v. Data are given on defrosting with a Hyviz windshield at power levels between 0.3 and 1.0 W/inches squared (approximately 50-150 W/feet squared showing a defrosting time of about 5 min from 0 degree F for the higher power level.
