Abstract
We propose an electrically tunable narrow bandwidth bandpass filter in which the band gap of polymer stabilized blue phase liquid crystal (PS-BPLC) with distinct crystallographic orientations can be tuned on electric field sweeps from red to blue with a narrow bandwidth (27 nm). Owing to the narrow bandwidth which can cut specific wavelength, it could be used as a filter to enhance color gamut in LCDs. In addition, the proposed bandpass filter exhibits much wider viewing angle property than Cholesteric LC bandpass filter.
