OPTICAL TOUCH PANEL

摘要

The optical touch panel according to the present invention includes an optical waveguide which delivers an optical signal; a light source unit which generates an optical signal and provides the signal for the optical waveguide; and a light detector which measures the intensity of the optical signal which has passed through the optical waveguide. An optical waveguide includes multiple sensor units, and is connected to one corresponding light detector. Each sensor unit is configured to form a pre-fabricated pattern so that the light signals which are to be detected in the light detector have different intensities.
