Description

Touch sensor-antenna module and display device including the same {TOUCH SENSOR-ANTENNA MODULE AND DISPLAY DEVICE INCLUDING THE SAME}

The present invention relates to a touch sensor-antenna module and a display device including the same. More specifically, it relates to a touch sensor-antenna module including an antenna pattern and a touch sensor layer and a display device including the same.

Recently, as the information society develops, wireless communication technologies such as Wi-Fi and Bluetooth are combined with display devices and implemented in the form of, for example, smart phones. In this case, an antenna may be coupled to the display device to perform a communication function.

As mobile communication technology has recently evolved, an antenna for performing communication in an ultra-high frequency band corresponding to, for example, 3G to 5G needs to be coupled to the display device.

On the other hand, a touch panel or touch sensor, which is an input device that allows a user to input commands by selecting instructions displayed on the screen with a human hand or an object, is combined with a display device to implement an image display function and information input function together. Electronic devices are being developed. For example, as in Korean Patent Publication No. 2014-0092366, a touch screen panel in which a touch sensor is coupled to various image display devices is being developed.

As the antenna and the touch sensor coexist in one display device, for example, mutual signal interference may degrade desirable gain characteristics of the antenna and disturb impedance characteristics for receiving a desired frequency. Also, as the antenna pattern is inserted, sensing resolution and sensing sensitivity of the touch sensor may be reduced.

For example, Korea Patent Publication No. 2003-0095557 discloses an antenna structure built into a portable terminal, but fails to consider compatibility with other electric elements such as a touch sensor.
