摘要

直接式LED背光单元(BLU)在液晶显示中需要高均匀度的广角照明。微图案复合光学表面作为单透镜表面，通过在半球形表面设计微图案阵列，可以提供超过150度的广角LED照明角度。

Micropatterned complex optical surface for wide angle illumination

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.
