Embodiment 1

[0045] This example will specifically explain the touch screen of the portable electronic product disclosed in the present invention. Such as figure 2 As shown, the touch screen of a portable electronic product provided in this example includes a panel 4, an ink layer 3, a transparent adhesive layer 2, and a sensing layer 1 sequentially from top to bottom;

[0046] The ink layer 3 is arranged on the periphery of the lower surface of the panel 4, and the middle area of ​​the lower surface of the panel 4 is a visible area not coated with ink;

[0047] Wherein, a layer of anti-foaming adhesive layer 5 is coated on the surface of the ink layer 3 and the visible area; the sensing layer 1 is pasted on the anti-foaming adhesive layer 5 through the transparent adhesive layer 2 .

[0048] Among them, the panel 4 can be two types of glass and film, and the film type specifically includes PC, PMMA or a composite board of PC and PMMA, etc., and its thickness generally varies slightly ac...

Embodiment 2

[0064] This example discloses a portable electronic product, which includes the touch screen described in Embodiment 1 above. Among them, portable electronic products may include mobile phones, tablet computers, e-books, PDAs, etc. In this example, only the touch screen on the portable electronic products is improved, and other components and their manufacturing methods on the electronic products are not improved. The touch screen has been specifically described in Embodiment 1, so it will not be repeated.

[0065] With the portable electronic product disclosed in this example, since the ink layer 3 in the touch screen and the surface of the visible area are coated with a layer of anti-foaming rubber layer 5, the above-mentioned anti-foaming rubber layer 5 can effectively eliminate the contact between the ink layer 3 and the visible area. The height difference between the glass panels provides a flat bonding surface for subsequent lamination with the transparent adhesive layer...

Embodiment 3

[0067] This example will specifically explain the preparation method of the touch screen of the portable electronic product disclosed in the present invention.

[0068] Such as Figure 5 Shown, described preparation method comprises the steps:

[0069] Step SA, preparing the sensing layer 1;

[0070] Step SB, setting a transparent adhesive layer 2 on the upper surface of the sensing layer 1;

[0071] Step SC, forming an ink layer 3 on the periphery of the lower surface of the panel 4, and forming a visible area not coated with ink in the middle area of ​​the lower surface;

[0072] Step SD, coating a layer of anti-foaming adhesive layer 5 on the ink layer 3 and the visible area;

[0073] Step SE, pasting the sensing layer 1 compounded with the transparent adhesive layer 2 on the panel 4 with the anti-foam adhesive layer 5 .

[0074] Wherein the above-mentioned steps SA, SB prepare the sensing layer 1, and the process of setting the transparent adhesive layer 2 on the sensi...

Abstract

The embodiment of the invention provides a portable electronic product capable of eliminating combination bubbles, a touch screen for the same and a touch screen preparation method, and aims to solve the problem of combination bubbles between an ink layer and a panel in the prior art. The touch screen for the portable electronic product sequentially comprises a panel, an ink layer, a self-adhesive tape layer and a sensing layer from top to bottom, wherein the ink layer is arranged on the peripheral edge of the lower surface of the panel; the middle area of the lower surface of the panel is a visible area which is not coated with ink; the surfaces of the ink layer and the visible area are coated with an anti-bubble adhesive layer; the sensing layer is adhered to the anti-bubble adhesive layer through the self-adhesive tape layer. According to the touch screen for the portable electronic product, a height difference between the ink layer and the glass panel can be effectively eliminated to prevent the formation of the combination bubbles by virtue of the anti-bubble adhesive layer. Therefore, the touch screen is more favorably thinned, the thickness of the ink layer of the touch screen can be ensured, color effects of the panel of the touch screen can be ensured, and higher overall color uniformity can be achieved.

Description

technical field [0001] The invention relates to the field of portable electronic products, in particular to the field of touch screens on portable electronic products. Background technique [0002] With the increasing popularity of consumer electronics, more and more portable electronic products use touch technology. There are many types of touch technology on the market, which can be roughly divided into the following types: resistive, capacitive, surface acoustic wave, Vibration induction type, infrared type, etc. Among them, the capacitive touch screen (mainly referring to the projected capacitive type) has become the leading technology in the market due to its high technical threshold, light weight, and wide application in size. [0003] At present, the basic structure of capacitive touch screen is as follows: figure 1 shown. It includes panel 4, ink layer 3, transparent adhesive layer 2 and sensing layer 1 from top to bottom; [0004] The ink layer 3 is arranged on ...
