Abstract
We propose a backlight system for a vertical-field-switching blue phase liquid crystal display. Because the blue phase liquid crystal display needs an oblique incident light source of a backlight system, we designed the backlight system that consisted of a light guide plate and a specially designed prism film. We simulated the backlight system by optical software (TraceProTM) and the performance of the blue phase liquid crystal display by liquid crystal software (TechWiz). The result showed that the contrast ratio of the blue phase liquid crystal display can be over 2000 and the uniformity was 86%. The designed applicable backlight system will be illustrated in the vertical field switching blue phase liquid crystal display.
