Transparent and Photo‐stable ZnO Thin‐film Transistors to Drive an Active Matrix Organic‐Light‐ Emitting‐Diode Display Panel

Abstract

Transparent ZnO thin-film transistors (TFTs) with a defect-controlled channel and channel/dielectric interface maintain good photo-stability during device operation. The figure shows a cross-sectional view of a top-gate ZnO-based transparent TFT/storage capacitor cell structure, connected to front-panel organic-light-emitting-diode pixels to operate in bottom emission mode.
