Broadband Wide-View Lcds With Small Color Shift

We proposed a broadband wide-view liquid crystal display (LCD) with two biaxial films. Based on different dispersion properties of these two films, we optimized their in-plane phase retardation values to minimize the light leakage and color shift over the whole viewing cone. The broadband wide view and low color shift properties will further lead to high contrast ratio and good color quality, especially for low gray level images. © 2009 IEEE
