This invention describes a novel solution to conserve battery and to overcome cold-start artifacts by maintaining the pixel charge traps at a stable value at all times. The design of NIP photodiode and TFT combination requires very low current (in order of hundreds of μΑ) to stay biased at all times. This allows the pixel charge traps to be easily maintained at a stable value with low power consumption. Power consumption is kept at a minimum by keeping all panel electronics off and only the pixels biased. In addition, keeping the pixels biased helps to overcome the cold-start artifact in the very first image.
