Abstract

A touch device comprises a light-transmitting display region and a non-light-transmitting frame region located on the outer side of the display region, wherein the frame region comprises a touch region and a wiring region. The touch region is arranged between the display region and the wiring region, multiple sensing pads for sensing touch operations are distributed in the display region and the touch region according to a specific rule, and multiple connecting path lines are located in the wiring region and electrically connected with the corresponding sensing pads and are used for being connected with the sensing pads and a drive circuit so as to obtain electrical signals. The ends of at least a part of the connecting path lines electrically connected with the sensing pads extend into the touch region, the part of the connecting path lines and the sensing pads are stacked in arrangement, insulating layers are arranged between the sensing pads and the connecting path lines which are stacked, a plurality of through holes are formed in the insulating layers, and the sensing pads located in the touch region are electrically connected with the corresponding connecting path lines in the wiring region. The touch device is narrow in frame.

Description

technical field [0001] The invention relates to a touch device. Background technique [0002] Currently, touch devices with touch functions are more and more commonly used. Generally speaking, a touch device includes a display panel and a touch panel. Wherein, the touch panel can be built into the display panel or attached to the display panel. At present, touch panels are roughly classified into resistive touch panels, optical touch panels, and capacitive touch panels according to different sensing methods. [0003] The interface circuit of the resistive touch panel is mainly a serial port data circuit and a USB data interface circuit, generally there are four-wire and five-wire systems. The panel part of the resistive touch panel is a multi-layer composite film. Taking the four-wire resistive touch panel as an example, the four-wire resistive touch panel is covered with two layers between the surface protective coating and the substrate. Transparent conductive layer, t...
