ABSTRACT:
A multi-contact LCD heater system which include several contacts disposed around the periphery of a resistive film deposited on a substrate in which each contact is dynamically controlled in response to input from various temperature sensors. The control allows for each contact to be connected to a high potential or a low potential source or remain isolated. Spatial, temporal and amplitude modulation of the heat applied to the LCD is achieved.
