Abstract

We propose a high-efficiency backlight module without BEFs and achieve almost the same half-luminance angle as the conventional backlight module does. This backlight module guides light with two different modes. We can get the two-fold improvement in both total optical efficiency and on-axis luminance by controlling the arrangement of microstructures.
