- 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 GS and no TFT with zero V GS 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. © 2012 IEEE.
