Abstract:
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.
Abstract:
Disclosed are an apparatus and a method for sensing pressure using an optical waveguide sensor. The apparatus for sensing pressure using an optical waveguide sensor, includes: a light source radiating light; an optical waveguide panel emitting some of the radiated light outside through a plurality of light transmitting regions previously formed, and changing an amount of totally reflected light according to pressure applied to at least one of the plurality of light transmitting regions; a detector detecting the amount of light; and an analyzer determining intensity and a location of the pressure according to the detected amount of light.
Abstract:
Provided are a microlens array film and a display device including the same. The microlens array film includes a first transparent electrode and a second transparent electrode facing each other and a flexible polymer layer placed between the first and the second transparent electrodes. Lenses may be freely deformed by regulating voltages applied to the first and second transparent electrodes.
Abstract:
Provided is a thin film type actuator having multi-operation points, capable of various feels of touch or sounds. The film type actuator includes an upper plate and a lower plate, formed of a single plate. Between the upper plate and the lower plate, pairs of electrode parts capable of attracting one another via an electrostatic force. Since each of the pairs of electrode parts functions as an operation point and the upper plate and the lower plate are formed of the single plate, movements of the respective operation points in such a way that a new physical movement different from an original individual movement is generated to generate a haptic feel or a sound. It is possible to generate various haptic feels or sounds by modulating and combining amplitudes and frequencies of the respective operation points.
Abstract:
Provided is a touch screen for generating a haptic sense that may minimize a structure added for haptic generation by simultaneously employing a single electrode layer that constitutes an existing touch panel as an electrode layer for transferring the haptic sense. A touch screen for generating a haptic sense according to an exemplary embodiment of the present disclosure includes a touch panel including at least one substrate, each formed with at least one electrode, and an additional electrode to generate the haptic sense on a portion touched on the touch panel using an electrostatic force that occurs between the additional electrode and a predetermined electrode among the at least one electrode.
