Transmissive and Transflective Blue-Phase LCDs With Double-Layer IPS Electrodes

A double-layer in-plane-switching electrode design is proposed for transmissive and transflective blue-phase liquid crystal displays. The new design significantly reduces the operating voltage in transmissive display by 60%; in transflective displays where the bottom-layer electrodes are made of conductive reflectors, it increases transmittance to 98%, achieves single gamma driving and enhances sunlight readability.
