Abstract

A heater, used in a Liquid Crystal Display (LCD) pixel array that uses a common voltage polysilicon line to supply heat to the pixel elements, instead of using active control transistor input lines, such as gate input lines. The approach permits the display to be activated during the warm-up process.
