Since Kikuchi developed polymer-stabilization process for widening the blue-phase liquid crystal(BPLC)temperature range in 2002 [1] and Samsung demonstrated the first BP LCD prototype in 2008 [2],whole world is waiting for the era of this disruptive technology to come.BP-LCD exhibits several revolutionary features,such as submillisecond gray-to-gray response time,no need for alignment layer,optically isotropic dark state for inherently wide view,and large cell gap tolerance for easing fabrication provided that in-plane switching(IPS)electrodes are employed [3].With sequential RGB LED colors,the spatial color filters can be eliminated so that both optical efficiency and resolution density are tripled.
