Abstract
The scan driver composed of oxide thin-film transistors (TFTs) tends to exhibit anomalously high power consumption because the oxide TFT often has negative threshold voltage. In order to resolve this problem, we have invented a new scan driver circuit in which most TFTs are turned off with negative V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">GS</sub> and no TFT with zero V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">GS</sub> is located between the high and low supply voltages. As a result, we could maintain the power consumption within six times of the normal value in spite of the negative threshold voltage of the oxide TFT.
