Title:
TOUCH SENSOR FALSE DETECTION PREVENTION STRUCTURE, AND ELECTRONIC DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/105305
Kind Code:
A1
Abstract:
Disclosed are a touch sensor false detection prevention structure and electronic device comprising the same. A touch sensor false detection prevention structure according to an embodiment of the present invention is provided to an electronic device which comprises: a casing body provided with a through path-forming part through which a sensor sheet passes; a circuit substrate attached inside the casing body; and a touch panel which is electrically connected to the circuit substrate by the sensor sheet. An essential part of the configuration of the touch sensor false detection prevention structure is that protruding sections, which are provided so as to protrude at a prescribed height, are formed upon the inner surfaces of both lateral parts of the through path-forming part, when viewed in a plan view, thereby limiting movement in a portion of both lateral parts of the sensor sheet. As a result of the touch sensor false detection prevention structure, it is possible to prevent a touch sensor from erroneously sensing a touch if a product shakes during operation due to providing the through path-forming part and protruding sections, which have specific structures.
