Problems solved by technology

Because the sensing electrode layer located in the peripheral area covers the black light-shielding layer, and the black light-shielding layer has a certain thickness, that is, the sensing electrode layer located in the peripheral area covers the black light-shielding layer stepwise, and the sensing electrode layer needs to span the black light-shielding layer. The thickness of the black light-shielding layer creates a slope, which causes the resistance value of the sensing electrode layer to fluctuate easily, thereby affecting the accuracy of touch detection.

Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] Referring to FIG. 1 , it shows a schematic cross-sectional view of a touch display device 300 according to an embodiment of the present invention. The touch display device 300 includes a touch device 100 and a display panel 200. The display panel 200 is, for example, a liquid crystal display panel or other display components. The display panel 200 can be attached to the bottom of the touch device 100 through an adhesive layer (not shown). The touch device 100 can be, for example, a capacitive touch device, having a sensing area 100A and a peripheral area 100B surrounding the sensing area 100A.

[0013] The touch device 100 of the embodiment of the present invention is a touch structure (touch on lens) in which all touch components are arranged on the protective cover 102, the outer surface of the protective cover 102 is the tou...

Abstract

The present disclosure relates to a touch technology, and more particularly to a touch device and a fabrication method thereof. The touch device comprises a sensing area and a peripheral area. The touch device further comprises a sensing electrode layer, a shading layer, a signal transmission line layer, and a conductive layer. The sensing electrode layer extends from the sensing area to the peripheral area. The shading layer is disposed on the peripheral area to overlay the sensing electrode layer and has a through hole to expose a portion of the sensing electrode layer. The signal transmission line layer is disposed on the shading layer and does not cover the through hole. The conductive layer fills the through hole and electrically connects the sensing electrode layer. In addition, a fabrication, method of a touch device is also provided.

Description

technical field [0001] The present invention relates to a touch technology, and in particular to a touch device and a manufacturing method thereof. Background technique [0002] In recent years, touch devices have been widely used in various electronic products, such as mobile phones, personal digital assistants (PDAs) or palmtop personal computers. Among them, there is currently a thin design of a touch device, the touch device includes a protective cover and a touch component, the touch component is directly attached to one side of the protective cover, and the other side of the protective cover is It is for users to touch to input information or control electronic products. In this way, the protective outer cover has both the original protection function and the new function of carrying the touch component, and the touch substrate that originally needs to carry the touch component can be omitted. Because of this touch The control device has the advantage of being light a...
