8‐2: Invited Paper: High Mobility Top Gate Self‐alignment Oxide TFT Technology for 14.5 inch 3K*2K Narrow‐bezel Notebook LCD

We have developed a high mobility over 20 cm2 /V•s Top Gate Self‐alignment (TGSA) Oxide TFT technology with on‐state current 60μA. The TGSA TFT with dual gate have two electron channel realizing the higher mobility than single gate TFT. The higher mobility make it possible for high resolution, high refresh rate and narrow‐bezel design of LCDs. Therefore, combing with the source line DEMUX 1:2 circuit design, we fabricated a 14.5 inch notebook liquid crystal display (LCD) with resolution of 3K*2K successfully using the high performance TGSA TFTs, achieving the refresh rate of 165Hz and panel left and right border of 1.7mm.
