Abstract
An improved Liquid Crystal Display (LCD) heating system is provided. Resistor meshes, in particular VCOM resistor heating meshes, in the pixel array improve capacity of the display heater (heating system) so that the display is heated faster from low temperatures. The resistor mesh design provides much lower resistance from one point in the pixel array to an edge than pixel-to-pixel horizontal VCOM resistance, thus reducing horizontal crosstalk. Further, the approach permits the display to be active during the warm-up process.
