Abstract
Official abstract text for this publication.
A touch panel according to an embodiment of the present invention includes: a pressure detection unit including a light-source unit configured to generate an optical signal, an optical waveguide configured to transfer the optical signal, a sensing unit contacting with the optical waveguide to receive the optical signal according to an intensity of pressure applied externally, and a light-receiving unit configured to receive the optical signal transferred through the optical waveguide from the sensing unit; and an actuator contacting with the pressure detection unit to cause a deformation of a material according to the pressure intensity, wherein the actuator provides a tactile feedback through a vibration according to the pressure intensity.
First claim
