Abstract
A prism sheet () includes a substrate () and a plurality of prism structures (). The substrate includes a plurality of diffusing particles () dispersed therein. The prism structures are at a light output side of the substrate. The diffusing particles can diffuse light beams traveling through the substrate. This configuration performs the same function as that of a diffusing sheet of a conventional backlight module. The prism structures can gather light beams to improve a brightness of a backlight module () incorporating the prism sheet. Thus, the backlight module can provide bright and uniform light at a low cost and while having a reduced thickness.
