TOUCH SENSOR BASED ON FABRY-PEROT STRUCTURE

摘要

PURPOSE: A touch sensor based on Fabry-perot structure is provided to simplify the structure of a touch sensor using light from a display unit as a sensing signal. CONSTITUTION: A first laminated structure(110) penetrates light of a specific wavelength band of incident light. A second laminated structure(120) is laminated on the front side of the first laminated structure. The second laminated structure uses the light of the specific wavelength band which is received from the first laminated structure as a sensing signal. The second laminated structure detects the touch through the light of the specific wavelength band. A transparent substrate(100) is arranged on the rear side of the first laminated structure. A protective transparent substance layer(130) is arranged on the front side of the second lamination structure.
