Wide-Angle View PDLC Displays

摘要

When polymer liquid crystals are used as the matrix for polymer dispersed liquidcrystal materials, it is possible to index match for all directions of incident light to create light shutters which are haze free in the transparent state for all angles of view. Displays with an unlimited view angle become possible. Polymer dispersed liquid crystal (PSLC) light shutters have been of interest in recent years for applications in displays because of their suitability for the fabrication of large scale, low cost, flexible devices and, because of the absence of polarizers, their potential for displays with improved brightness. Until now, the materials used for these displays have consisted of low-molecular weight liquid crystal dispersed with optically isotropic polymers.
