The speed of the TFT slows and allows less light to pass through the filter. The end result is a lower contrast. In some cases there is a flicker.



It is possible to add a heater to the TFT to keep the temperature above the threshold. The heater can be a film that is applied to the glass or even several ¼ resistors could be added to generate heat. Note: heaters and resistor will draw a large amount of current and can drain the battery.
