Embodiment Construction

[0082] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementation cases of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0083] An uneven cover or backing layer is primarily characterized by its surface roughness. A common parameter for evaluating surface roughness is the arithmetic mean roughness. In the following description, when the term roughness is used, it means arithmetic mean roughness.

[0084] In the following, whenever the term sensing light is used, it is intended to denote light transmitted and refracted in the deformable light guide for the purpose of sensing pressure and / or touch position.

[0085] image 3 A cross-sectional view of a central portion of a smart surface 3000 according to an embodiment is schematically shown. Here, the term center is intended to be in contrast to periphery, and should not be interpreted as denoting ...

Abstract

The present invention relates to a smart surface for detecting the position and / or pressure of at least one touch, the smart surface comprising: a support substrate (1100); a deformable light guide (1200) over the support substrate (1100), the deformable light guide (1200) for transmitting the sensing light; a capping layer (2500) over the deformable light guide (1200); and an intermediate layer (3600) between the deformable light guide (1200) and the cover layer (2500).

Description

technical field [0001] The invention relates to a smart surface for detecting the position and / or pressure of at least one touch. Background technique [0002] Smart surfaces refer to embedding tactile functions on surfaces made of different materials, textures, and geometric shapes, so as to realize user interaction and gesture recognition with smart surfaces. A smart surface can be considered a smart surface for functionality provided by a mobile phone / tablet via pointing operation provided by a rigid surface traditionally made of glass or by a touchpad on a plastic / glass surface in a portable laptop / notebook computer. [0003] In general, a smart surface is a system consisting of a sensor that senses a touch input from a user and a control unit that processes the touch input. Compared with ordinary touch digitizers (such as touch screens and trackpads) that need to determine the presence or absence of touch events in the entire area, smart surfaces can selectively respon...
