TOUCH SENSOR MODULE FOR DISPLAY AND OPTICAL DEVICE CONTAINING THE SAME

摘要

PURPOSE: A touch sensor module for display and optical apparatus including the same are provided to reduce control errors by reducing the thickness of an optical apparatus. CONSTITUTION: An optical source(210) emits single color light. A light splitter(220) emits light of a light source to a collimator lenses and emits the light reflected from the collimator lenses to a detector. A deflected prism(240) converts light emitted from the collimator lenses by locating the light splitter and the collimator lenses on the same line. A light detector(270) faces to the collimator lenses by locating the deflected prism, the collimator lenses, and the light splitter on the same line.
