Abstract
A low-power and small-area scan driver using depletion-mode amorphous-InGaZnO (a-IGZO) thin-film transistors (TFTs) is proposed for 10-inch quadruple extended graphics array (QXGA, 2048 x 1536) panels. The proposed scan driver is realised in a small area using 11 TFTs and improves power consumption by removing short circuit current. Measured results show that the power consumption of the proposed scan driver with 10 stages is 710 mu W at the scan frequency of 92.2 kHz and the output voltage swing of 20 V.
