Embodiment Construction

[0046] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] In the prior art, the edge routing of the touch sensor in the touch screen includes a ground wire, a signal protection wire, and a touch signal receiving wire, and between the ground wire and the signal protection wire, the signal protection wire and the signal protection wire Due to the joint action of water vapor, potential difference and high temperature during the operation evaluation test, short circuit faults are prone to occur between the touch signal receiving lines.

[0048] In order to solve the above problems, a touch device disclosed in the embodiment of the present invention, refer to figure 1 As shown in the schematic diagram of the touch control device, the touch control device includes a base, and the base i...

Abstract

The invention provides a touch control device and a preparation method of the touch control device. The touch control device comprises a substrate, and the substrate is provided with a grounding wire,a signal protection wire, a touch control signal receiving wire, a first shielding wire and a second shielding wire; the signal protection lines are arranged between the grounding lines and the touchsignal receiving lines at intervals. The first shielding wire is arranged between the grounding wire and the signal protection wire at intervals; and the second shielding lines are intermittently arranged between the signal protection lines and the touch signal receiving lines. According to the embodiment of the invention, the first type shielding wire is arranged between the grounding wire and the signal protection wire to improve poor short circuit between the grounding wire and the signal protection wire; and a second shielding line is arranged between the signal protection line and the touch signal receiving line to reduce short circuit between the signal protection line and the touch signal receiving line. And the cost is not increased under the condition of reducing the short circuit.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch device, a display device and a manufacturing method of the touch device. Background technique [0002] With the continuous development of electronic technology, more and more display devices begin to use the human-computer interaction mode to realize the user's operation of the display device. At present, the human-computer interaction mode has entered the touch sensing mode from the mechanical button mode. The touch screen provides users with a touch sensing mode, and its reliability determines the quality of the entire display device. The touch sensor is an important component in the touch screen, and if the touch sensor fails, it will affect the touch effect of the entire touch screen. [0003] At present, short-circuit defects are relatively common defects in touch sensors, especially in the case of environmental reliability evaluation of products with ...
