Embodiment 2

[0035]Add 10 grams of acrylic resin (10% by weight), 58 grams of acrylic monomer (58% by weight), and 30 grams of refractive index matching material (30% by weight) into a container, and then stir the mixture of the above materials evenly After standing still for defoaming, a mixed solution of the optical glue is formed in the container. Wherein the above further includes adding 0.5 grams of photoinitiator (0.5% by weight), 0.5 grams of light stabilizer (0.5% by weight), and 1 gram of adhesion promoter (1% by weight). The above steps complete the optical matching glue of the present invention, and its form is liquid. The preparation of the optical matching adhesive may further include a step of coating the above-mentioned well-mixed solution on a substrate, and performing a curing step to complete the optical matching adhesive of the present invention, which is in a solid state. Wherein, the curing step is preferably an ultraviolet light irradiation step, but not limited ther...

Embodiment 1

[0047] Please refer to figure 1 , figure 1 A schematic diagram of a touch panel according to the first preferred embodiment of the present invention. Such as figure 1 As shown, the touch panel 1 includes a substrate 10 , a sensing layer 12 and an optical matching glue 18 . Wherein the sensing layer 12 is located on the substrate 10, the sensing layer 12 includes a plurality of electrode patterns 14 arranged at intervals, these electrode patterns 14 are arranged on at least one surface of the substrate 10 with gaps 17 between each other, optical matching glue 18 Then it is located on the sensing layer 12 and fills the gap 17 between the electrode patterns 14 , wherein the optical matching glue 18 has a refractive index matched with the electrode patterns 14 . In this way, the optical matching adhesive 18 has both adhesiveness and refractive index matching functions, and thus can reduce the appearance problems of the touch panel caused by the difference in refractive index wi...

Embodiment 3

[0055] image 3 According to the third preferred embodiment of the present invention, a schematic diagram of the stacked structure of applying the optical matching adhesive of the present invention to a touch panel is shown. The touch panel 3 includes a substrate 20 , a sensing layer 22 and an optical matching glue 28 . The biggest difference from the second preferred embodiment is that the touch panel 3 further includes a cover substrate 40 . The sensing layer 22 including the electrode pattern 24 in the first direction, the insulating layer 25 and the electrode pattern 26 in the second direction is located on the first surface S1 of the substrate 20, and the optical matching glue 28 can be arranged on the sensing layer 22 and the upper cover substrate. 40 , that is, the substrate 20 and the upper cover substrate 40 are attached to each other through the optical matching glue 28 . The structures and properties of the sensing layer 22 and the optical matching adhesive 28 are ...

Abstract

A touch panel, comprises a substrate, a sensing layer disposed on the substrate, wherein the sensing layer includes a plurality of electrode patterns disposed on at least one surface of the substrate, and arranged in interval; an optical matching glue disposed on the sensing layer and filled in the intervals, wherein the refractive index of the optical matching glue matches the refractive index of the sensing layer. The present invention further comprises an optical matching glue and the manufacturing method thereof. When using the touch panel of the present invention, the defects of appearance caused by the refractive index difference between the electrode pattern and the intervals can be reduced without any additional process.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch panel and its manufacturing method, an optical matching glue applied to the touch panel and its manufacturing method. Background technique [0002] In today's market of various consumer electronics products, portable electronic products such as personal digital assistants (PDAs), mobile phones (mobile phones), notebook computers (notebooks) and tablet computers (tablet PCs) have been widely used. Control panel (touch panel) as its interface tool for data communication. In addition, since the current design of electronic products is light and thin, it is hoped that traditional input devices such as keyboards and mice can be omitted in product design, especially driven by the demand for tablet computers that emphasize humanized design. The control panel has become one of the key components as if it has become a new user interface. [0003] In a general touch panel,...
