Problems solved by technology

[0008] In this case, since capacitance is formed between the conductive layer and the touch electrode due to a large potential difference between the conductive layer and the touch electrode in the edge region of the display panel near the position where the conductive layer is connected to the ground, the display Touches in the edge area of ​​the panel are not recognized
[0009] In addition, when the potential of the ground terminal rises to improve touch recognition performance, it may occur to prevent electrostatic discharge or affect logic signals applied to the gate driving circuit for driving of gate lines

Abstract

The present disclosure enables sensing of touch input at one or more edges of a touch-enabled device while preventing touch drive signals for driving pixels of a touch panel of the device from grounding. An aspect of the present disclosure provides a touch display device including a first substrate and a second substrate; a plurality of touch electrodes between the first substrate and the second substrate; a ground line coupled to a part of the first substrate via a resistor ; and the conductive layer coupled to the ground wire through the conductive member.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2017-0131353 filed on October 11, 2017, the entire contents of which are hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] The present disclosure relates to a touch display panel and a touch display device. Background technique [0004] With the development of the information society, various requirements for display devices for displaying images have increased, and various types of display devices such as liquid crystal display devices, plasma display devices, and organic light emitting display devices are used. [0005] The display device provides a function of recognizing a user's touch on a display panel and performing input processing based on the recognized touch in order to serve the user. [0006] For example, a touch display device capable of touch recognition may embed a plurality of ...
