However, if figure 2 As shown, for the plan design of OCA (Optically Clear Adhesive) optical glue lamination, due to the strong adhesive force of OCA optical adhesive, large stretchability and the influence of temperature changes such as heat during the lamination process, the lamination of the overlapping area The lead wire will release the stress and produce a pulling effect, which will easily lead to damage to the contact between the lead wire and the conductive layer in the overlapping area, resulting in a higher overlapping impedance and affecting the touch performance

Embodiment Construction
[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0033] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning...

Disclosed are a touch control film and a manufacturing method therefor, and a touch control module. In the touch control film, a fitting layer arranged on a first functional layer and a second functional layer is in indirect contact with an overlapping structure, or a portion of the fitting layer corresponding to the overlapping structure is separated from the portion of the fitting layer not corresponding to the overlapping structure, such that when stretching out and drawing back and deforming, the portion of the fitting layer not corresponding to the overlapping structure does not pull on the overlapping structure, thereby achieving the function of releasing the effect of a fitting retraction stress or a deformation stress to facilitate the improvement in the contact stability and reliability of a region where the overlapping structure is located. The touch control film can be applied to a film layer fitting product having an overlapping structure, and can eliminate the effect of a fitting layer on the connection stability of the overlapping structure, thereby ensuring the performance of the product and improving the yield of the product.
Description
technical field [0001] The invention relates to the field of touch technology, in particular to a touch film, a manufacturing method thereof, and a touch module. Background technique [0002] At present, in the silver paste process, especially in the process of thin film conductive layer with silver glue, it is necessary to use the design of contact and conduction between high conductivity materials such as silver glue and the conductive layer. Leads such as silver glue are in contact with the conductive layer by lapping the lead at the edge of the conductive layer, such as figure 1 shown. The reliability of the contact between the lead wire and the conductive layer in the overlapping area will directly affect the touch performance of the product. However, if figure 2 As shown, for the plan design of OCA (Optically Clear Adhesive) optical glue lamination, due to the strong adhesive force of OCA optical adhesive, large stretchability and the influence of temperature chang...
