Abstract

The present invention relates to a multi-sensor structure and image display device including the same. The multi-sensor structure of embodiments of the present invention comprises a base layer; a first touch-fingerprint sensor electrode layer arranged on the upper surface of the base layer; a second touch-fingerprint sensor electrode layer arranged at the upper level of the first touch-fingerprintsensor electrode layer; and an antenna electrode layer spaced from the first touch-fingerprint sensor electrode layer and the second touch-fingerprint sensor electrode layer in a planar direction, and positioned at the same level as the first touch-fingerprint sensor electrode layer or the second touch-fingerprint sensor electrode layer. A sensor in which touch-fingerprint sensing and antenna signal sensing are integrated with high efficiency can be provided.

Description

technical field [0001] The invention relates to a multi-sensor structure and an image display device including the multi-sensor structure. More particularly, the present invention relates to a multi-sensor structure including a touch sensor and an antenna, and an image display device including the same. Background technique [0002] In recent years, touch sensors have been combined with image display devices to develop electronic devices that can use fingers or tools to select instructions displayed on image display devices to input users' intentions in various shapes, such as personal tablet. [0003] Furthermore, the above-mentioned image display device is combined with a communication device such as a smart phone. Thus, an antenna for high frequency or ultra high frequency band communication is combined with an image display device. [0004] In recent years, as various sensing functions are provided in image display devices, fingerprint sensors capable of directly sens...
