Emerging blue phase liquid crystal displays

Abstract

Device physics and electro-optical properties of emerging polymer-stabilized blue-phase liquid crystal displays (BPLCDs) are investigated. The novel protruded electrodes generate strong horizontal electric fields which penetrate deeply into the bulk LC layer. As a result, the operating voltage is reduced from over 50V rms to ~10 V rms , which for the first time enables the BP-LCDs to be addressed by amorphous silicon thin-film-transistors (TFTs). Kerr constant effect from the material side is also evaluated quantitatively. Widespread application of TFT BP-LCDs is foreseeable.
