Abstract: A new shift register circuit using oxide thin-film transistor (TFT) is proposed. As ever, it is important to research for promising high resolution and large size active matrix panel in display industry. For stable gate line operation expecially low voltage output, dual pull-down scheme using AC bias alternately has been widely used by many researchers to overcome degradation causing DC bias stress.?We fabricated Back channel etch structure TFT device for display backplane, and we extracted parameters for spice simulation. Fig 1. (a) shows a schematic of a proposed shift register circuit composed of 6 TFTs and 2 capacitors.?Single pull-down block is designed to protect output node from clock coupling when low output operation. And it is designed for successful operation in high frequency 130kHz for UHD display
