Problems solved by technology

In this way, the circuit layer is easily broken due to external force in the subsequent manufacturing process
And the area corresponding to the circuit layer has poor drop resistance and compression resistance, which affects the reliability of the touch device
[0003] However, if the size of the optical adhesive is increased, although the circuit layer can be completely covered, since the optical adhesive is generally a double-sided tape, the optical adhesive protruding from the liquid crystal display module will adhere to particles in the air (such as dust), making good It is difficult to increase the rate

Embodiment Construction

[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] figure 1 A cross-sectional view of a touch device 100 according to an embodiment of the present invention is shown. The touch device 100 includes a touch panel 105 , a display module 140 and a first adhesive layer 120 . The touch panel 105 has a circuit layer 112 around it. The first adhesive layer 120 is bonded between the touch panel 105 and the display module 140 . The first adhesive layer 120 covers the display module 140 and has a protrusion 123 protruding from an edge of the display module 140 . In addition, the protruding portion 123 of the first adhesive layer 120 at least covers the circuit layer 112 , and the surface 121 a of the protruding portion 123 away from the circuit layer 112 has no adhesive.

[0055] With such a design, the first adhesive layer 120 can not only fit the display module 140 and the touch pan...

Abstract

The invention provides a touch device, which comprises a touch panel, a display module and a first gluing layer, wherein a circuit layer is arranged around the touch panel; the first gluing layer is laminated between the touch panel and a display module; the first gluing layer covers the display module and is provided with an extrusion part which extrudes out of the edge of the display module; the extrusion part of the first gluing layer at least covers the circuit layer; and the surface, which is far away from the circuit layer, of the extrusion part does not have viscosity. The first gluing layer not only can laminate the display module and the touch panel but also covers the circuit layer, and a protection layer does not need to be additionally arranged on the circuit layer so as to guarantee that the circuit layer can not be easily broken due to external force pulling.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch device. Background technique [0002] Generally speaking, a touch device includes a touch panel and a liquid crystal display module attached together. A circuit layer for conducting touch signals is provided around the touch panel, which is usually located on the side of the touch panel facing the liquid crystal display module. When laminating the touch panel and the liquid crystal display module, optical clear adhesive (OCA) can be disposed between the touch panel and the liquid crystal display module. Since the purpose of the optical glue is to attach the liquid crystal display module, the optical glue is usually designed to be the same size as the liquid crystal display module. In such a design, the circuit layer of the touch panel is usually exposed and not covered by optical glue. As a result, the circuit layer is easily broken due to external force in the ...
