Abstract
A direct-type LED based back-light-unit (BLU) in LCD displays requires wide angle illumination with high uniformity. As a single lens surface, a micropatterned complex optical surface can provide wide angle LED illumination angle over 150deg by designing the micropattern arrays on the hemispherical surface.
