Embodiment 1

[0018] This embodiment provides a touch screen, which is suitable for various mobile terminals.

[0019] Such as Figure 2D Shown is a schematic structural diagram of the touch screen of this embodiment. The touch screen 200 includes a glass cover 201 , an ink layer 202 and a first non-transparent insulating layer 203 .

[0020] Wherein, the surface of the glass cover 201 is provided with a key area 204; the ink layer 202 is formed on the glass cover 201 and is located around the key area 204; the first non-transparent insulating layer 203 is formed on the glass cover 201 and is located in the key area 204 , that is, the ink layer 202 surrounds the first non-transparent insulating layer 203 .

[0021] In this embodiment, the first non-transparent insulating layer 203 and the ink layer 202 have different colors. The first non-transparent insulating layer 203 in this embodiment may specifically be a non-transparent insulating ink layer, and the specific material may be insula...

Embodiment 2

[0034] This embodiment makes further supplementary descriptions to Embodiment 1.

[0035] Such as Figure 3C As shown, in the touch screen 300 in this embodiment, in addition to the parts described in the first embodiment, a logo (Logo) area 301 is also provided on the glass cover 201 . On the sign area 301 , a second non-transparent insulating layer 302 formed simultaneously with the first non-transparent insulating layer is disposed on the sign area 301 , and the second non-transparent insulating layer 302 may specifically be a second non-transparent insulating ink layer. The second non-transparent insulating layer 302 and the first non-transparent insulating layer 203 are made of the same color and the same material

[0036] In this embodiment, the marking area 301 is a preset position on the glass cover 201 , and an ink layer 303 may be formed around the marking area 301 . The height of the second non-transparent insulating layer 302 is equal to the height of the ink lay...

Embodiment 4

[0047] This embodiment provides a method for manufacturing a touch screen, which is used to manufacture the touch screen of Embodiment 1.

[0048] Such as Figure 4 As shown, it is a schematic flow chart of the manufacturing method of the touch screen in this embodiment. The manufacturing method of the touch screen includes;

[0049] Step 401 , forming an ink layer around the key area of ​​the glass cover.

[0050]The glass cover plate in this embodiment is transparent glass, and the ink layer can be formed by applying ink multiple times and curing it, and the hollowed out part of the ink layer is the keypad.

[0051] Step 402, forming a first non-transparent insulating layer on the keypad.

[0052] Specifically, the first non-transparent insulating layer may be a non-transparent insulating ink layer, and the non-transparent insulating ink layer may be realized by printing and curing. The upper surface of the first non-transparent insulating layer may be flush with the upp...

Abstract

The invention provides a touch screen and a manufacturing method of the touch screen. The touch screen comprises a glass cover plate, an ink layer and a first non-transparent insulation layer, wherein a key region is arranged on the surface of the glass cover plate; the ink layer is formed on the glass cover plate and is positioned around the key region; the first non-transparent insulation layer is formed on the glass cover plate and is positioned on the key region; the first non-transparent insulation layer and the ink layer are in different colors. According to the touch screen and the manufacturing method of the touch screen, the first non-transparent insulation layer is formed on the key region; therefore, even if air bubbles are produced in the key region, a user cannot see the air bubbles due to coverage of the first non-transparent insulation layer, and the perception and the use of a user cannot be affected.

Description

technical field [0001] The invention relates to mobile terminal technology, in particular to a touch screen and a manufacturing method of the touch screen. Background technique [0002] Touch screens have been used more and more widely due to their many advantages such as durability, fast response, space saving, and easy communication. [0003] Such as figure 1 As shown, in the prior art, when the glass cover assembly (Cover Lens) 101 of the touch screen is attached to the sensing layer (Sensor) 102 , ink 103 is printed on the glass cover assembly 101 . If the customer requires more complex colors, it is often necessary to print multiple layers of ink on the glass cover assembly 101 . Like this, when pasting, because the space of transparent keypad 103 is very narrow, be easy to form air bubble 104 in the surrounding space of transparent keypad 103 when transparent keypad 103 is pasted, and be difficult to remove, promptly transparent keypad 103 is very narrow. It is easy...
