LIGHT GUIDE ASSEMBLY AND OPTICAL TOUCH MODULE USING THE SAME

摘要

A light guide assembly includes a hollow mounting pillar and a light guide member. The hollow mounting pillar includes a plurality of sidewalls; a receiving groove is defined by the sidewalls and has an inlet. One of the sidewalls serves as a transparent portion and the rest of the sidewalls each serve as a reflection portion. The light guide member is disposed in the receiving groove, and a light incident surface of the light guide member is exposed from the inlet. The light guide assembly has advantages such as having a simpler production process and higher production efficiency. An optical touch module adopting the light guide assembly is also disclosed.
