<p>A heater control circuit for the integral heater (l9) of a liquid crystal display comprising solid state switches (4l, 42) that simultaneoulsy connect and disconnect the high side and low side of the heater from power and ground, respectively, in response to display temperature. A bleed resistor (49) is connected between the heater (l9) and ground to bleed off accumulated charge that would erroneously drive one of the solid state switches into conduction.</p> |
