Problems solved by technology

However, the disadvantage of this method is that the degree of reduction is easily affected by material resolution, substrate expansion and contraction, equipment accuracy, resolution, process stability, and environmental cleanliness, and the wiring cannot be too close to each other, so that the wiring Area reduction is still quite limited

Embodiment Construction

[0059] The present invention can provide a touch device. Through special structural design and thermal pressure bonding technology, the traces can be completely attached to the side walls of the touch module and the display module, and there is no need to use the substrate to protect the Line, so that the bending radius of the line is not affected by the thickness and bendability of the substrate, which can greatly reduce the wiring area of ​​the line and achieve the purpose of narrow frame.

[0060] In order to better understand how the present invention achieves the above effects, the technology of the touch control device and its manufacturing method is described in detail here, please refer to Figure 2 to Figure 5 First, the structure of the touch device 1 will be described. The touch device 1 includes a display module 10 , a touch module 20 , a plurality of first wires 30 and a plurality of second wires 32 . The touch module 20 is disposed on the display module 10, and t...

Abstract

The present invention relates to a touch device and a method for manufacturing the same, comprising using a three-dimensional hot pressing technology to fix a release film having a plurality of first wires and a second wire on a touch module, so as to make a plurality of first wires , which extends to the first side of the touch module and is electrically connected to the first conductive pad of the touch module, and extends a plurality of second traces to the second side of the touch module and is connected to the touch module. The second conductive pad of the control module is electrically connected. Then, the release film is removed, and the wiring is cured by irradiation with a curing lamp, and then covered with a casing. The present invention can make the traces closely adhere to the side of the touch module through the technology of thermocompression bonding, and greatly reduce the wiring area, so as to achieve the purpose of narrow frame.

Description

technical field [0001] The present invention relates to the technology of a display, in particular to a touch device and a manufacturing method thereof. Background technique [0002] With the advancement of technology, the functions of portable electronic devices such as smart phones and tablet computers have become more and more powerful, and the relative degree of dependence of users on portable electronic devices has gradually increased. The requirements for the lightness, thinness, and ease of carrying of electronic devices are also gradually increasing. [0003] As a result, many manufacturers began to reduce the components of portable electronic devices, such as making smaller but more powerful semiconductor components. In addition, many manufacturers have also begun to reduce the routing area of ​​the outer border of the touch screen of the portable electronic device. This design modification not only makes the portable electronic device thinner and lighter, but also...
