Low voltage blue-phase liquid crystal displays

A protrusion electrode structure is proposed to dramatically lower the operation voltage of the emerging blue-phase liquid crystal displays (BP-LCDs). Simulation results indicate that the generated horizontal electric field is not only strong but also penetrates deeply into the bulk LC layer. As a result, a low voltage (∼10 Vrms) and reasonably high transmittance (∼70%) BP-LCD can be achieved. This approach enables the BP-LCDs to be addressed by amorphous silicon thin-film transistors (TFTs). Widespread application of TFT BP-LCDs is foreseeable.

Modeling of Blue Phase Liquid Crystal Displays

We propose a numerical model based on Kerr effect for simulating the electro-optics of polymer-stabilized blue phase liquid crystal displays (BP-LCDs). Parameters affecting the electro-optics of BP-LCDs in in-plane-switching (IPS) structures, such as wavelength, temperature, electrode dimension, and cell gap are investigated. In addition, viewing angle and color shift of IPS BP-LCDs are studied.
