Paper Abstract

We propose a light guide plate of an oblique incident light source for a vertical- field-switching blue phase liquid crystal display. The LGP consists of a designed microstructure bottom surface and other specially microstructure top surface. We simulated the LGP of a backlight system by optical software (TraceProTM) and the performance of the BPLCD by liquid crystal software (TechWiz). The result shows that the output rays mainly emit at 59° and the uniformity is 78.84%. The designed applicable light guide plate successfully increase the angles of oblique light source and provide a better uniformity of illumination for a vertical-field-switching blue phase liquid crystal display.
