Amorphous IGZO TFT-Based Pixel Buffer to Suppress Blue-Phase Liquid Crystal High-Frequency Effect

This letter discusses the frequency effect of polymer-stabilized blue-phase liquid crystal (BPLC) on the data voltages of a conventional pixel circuit and develops a new pixel buffer that exploits amorphous indium-gallium-zinc-oxidethin-film transistors (TFTs). During high-speed operations, BPLC ser...
