OPTICAL WAVEGUIDE FOR TOUCH PANEL |
摘要 |
The optical waveguide is disposed along the periphery of a display screen of a display of a touch panel. A light-emitting optical waveguide section and a light-receiving optical waveguide section are disposed in an alternating pattern along each edge of the display screen. Both of the light-emitting optical waveguide section and the light-receiving optical waveguide section are coupled together by placing end surfaces of end portions of the light-emitting optical waveguide section and the light-receiving optical waveguide section in abutment with each other. The light-emitting optical waveguide section includes cores each having an end portion provided in the form of a light-emitting lens portion. The light-emitting lens portion has an end surface provided in the form of a light-emitting lens surface. The light-receiving optical waveguide section includes cores each having an end portion provided in the form of a light-receiving lens portion corresponding to the light-emitting lens portion.
