Description

Technical Field

[0001] The utility model relates to a touch screen cover plate, in particular to a cover plate and a touch screen with a floating key pattern. Background Art

[0002] With the development of technology and the continuous change of consumer demands, electronic display products have become an indispensable part of daily life. Especially those products with touch screen and touch key functions, such as smart phones, tablet computers and smart wearable devices, etc., they not only provide a convenient operation experience, but also gradually become a carrier to show personal taste and style. Therefore, the design of the keys is not only functional, but also an important part reflecting the aesthetics of the product.

[0003] In the current market, there are a wide variety of electronic display products with touch key functions, and the design of touch keys has been increasingly valued by enterprises. In order to improve the market competitiveness of products, enterprises not only need to pay attention to the functionality of products, but also need to innovate continuously to meet the consumers' demands for novelty, beauty and practicality. Therefore, the design of the keys should not only consider its practicality, but also take into account the aesthetics and user experience.

[0004] The pattern design of traditional touch keys often forms by screen printing key patterns with ink on the back surface of the glass substrate. Although this method is stable and reliable, it lacks novelty and personalized features. Content of the Utility Model

[0005] In order to solve the above deficiencies of the prior art, the utility model provides a cover plate that can form a key pattern with a floating effect.

[0006] The utility model provides a touch screen, including the above cover plate.

[0007] The technical problems to be solved by the utility model are realized through the following technical solutions:

[0008] A cover plate with a floating key pattern, comprising:

[0009] A glass substrate having a front surface and a back surface disposed opposite to each other;

[0010] A high-temperature resistant ink pattern disposed on the front surface of the glass substrate and infiltrated into the interior of the glass substrate through the glass high-temperature tempering process;

[0011] A main color ink layer disposed on the back surface of the glass substrate;

[0012] A reverse cover light-shielding ink layer disposed on a surface of the main color ink layer away from the glass substrate.

[0013] Further, the high-temperature resistant ink pattern is a high-temperature resistant metal ink pattern, a high-temperature resistant water-based ink pattern, a high-temperature resistant composite ink pattern, or a high-temperature resistant polyurethane resin ink pattern.

[0014] Further, the thickness of the high-temperature resistant ink pattern is 5 - 20 μm.

[0015] Further, the glass substrate has a display area and a border area. The border area surrounds the display area, and the main color ink layer and the anti-cover light-shielding ink layer only cover the border area of the glass substrate, avoiding the display area of the glass substrate.

[0016] Further, there are multiple high-temperature resistant ink patterns, which are distributed at intervals on the border area of the glass substrate.

[0017] Further, the color of the main color ink layer is selected from one or more of black, white, and blue.

[0018] Further, the anti-cover light-shielding ink is black light-shielding ink.

[0019] Further, the thickness of the glass substrate is not less than 3 mm.

[0020] A touch screen includes a touch function layer and the above-mentioned cover plate. The touch function layer is disposed on the back surface of the cover plate. The cover plate has at least one high-temperature resistant ink pattern, and the touch function layer has at least one touch electrode. One high-temperature resistant ink pattern corresponds to one touch electrode.

[0021] Further, the touch function layer is a touch ITO layer.

[0022] The utility model has the following beneficial effects: The cover plate of the utility model is screen-printed with the high-temperature resistant ink pattern on the front surface of the glass substrate, and then the glass substrate with the high-temperature resistant ink pattern is subjected to a high-temperature tempering process. During the high-temperature tempering process, the molecular thermal motion of the glass substrate speeds up and the molecular gap increases, so that the high-temperature resistant ink pattern can penetrate into the interior of the glass substrate through the molecular gap of the glass substrate. Since the glass substrate has a certain thickness, the high-temperature resistant ink pattern penetrating into the interior of the glass substrate will present a suspended effect. Finally, the main color ink layer and the anti-cover light-shielding ink layer are screen-printed on the back surface of the glass cover plate in sequence to form the main color of the cover plate and prevent the ink of the cover plate from leaking light. And because the high-temperature resistant ink pattern has penetrated into the interior of the glass substrate, the high-temperature resistant ink pattern is not easily scratched by hard objects, increasing the wear resistance and scratch resistance of the key pattern.

[0030] Embodiment 1

[0031] As Figure 1 shown, a cover plate with a floating button pattern includes:

[0032] A glass substrate 21, having a front side and a back side which are oppositely arranged;

[0033] A high-temperature resistant ink pattern 22, disposed on the front side of the glass substrate 21, and penetrating into the interior of the glass substrate 21 through a high-temperature tempering process of the glass;

[0034] A main body color ink layer 23, disposed on the back side of the glass substrate 21;

[0035] A reverse cover light-shielding ink layer 24, disposed on a surface of the main body color ink layer 23 away from the glass substrate 21.

[0036] The cover plate of the present utility model is formed by screen-printing the high-temperature resistant ink pattern 22 on the front side of the glass substrate 21, and then performing a high-temperature tempering process on the glass substrate 21 with the high-temperature resistant ink pattern 22. During the high-temperature tempering process, the molecular thermal motion of the glass substrate 21 is accelerated and the molecular gap is increased, so that the high-temperature resistant ink pattern 22 can penetrate into the interior of the glass substrate 21 through the molecular gaps of the glass substrate 21. Since the glass substrate 21 has a certain thickness, the high-temperature resistant ink pattern 22 penetrating into the interior of the glass substrate 21 will present a suspended effect. Finally, the main body color ink layer 23 and the reverse cover light-shielding ink layer 24 are sequentially screen-printed on the back side of the glass cover plate to form the main body color of the cover plate and prevent the ink of the cover plate from leaking light. And because the high-temperature resistant ink pattern 22 has penetrated into the interior of the glass substrate 21, the high-temperature resistant ink pattern 22 is not easily scratched by hard objects, increasing the wear resistance and scratch resistance of the key pattern.

[0037] During production, first, the high-temperature resistant ink pattern 22 is screen-printed on the front side of the glass substrate 21 with high-temperature ink, and then the glass cover plate with the high-temperature resistant ink pattern 22 is sent for a high-temperature tempering process. During the high-temperature tempering process, the molecular thermal motion of the glass substrate 21 is accelerated and the molecular gap is increased, so that the high-temperature resistant ink pattern 22 can penetrate into the interior of the glass substrate 21 through the molecular gaps of the glass substrate 21, finally forming a key pattern with a suspended effect. After the high-temperature tempering process is completed, the main body color ink layer 23 and the reverse cover light-shielding ink layer 24 are sequentially screen-printed on the back side of the glass cover plate. The main body color ink layer 23 is used to provide the main body color for the cover plate (i.e., the color of the cover plate border), and the reverse cover light-shielding ink layer 24 is used to increase the light-shielding performance of the main body color ink layer 23, avoiding the light leakage phenomenon caused by too small ink density of the main body color ink layer 23.

[0038] The high-temperature resistant ink pattern 22 can be, but is not limited to, a high-temperature resistant metal ink pattern, a high-temperature resistant water-based ink pattern, a high-temperature resistant composite ink pattern, a high-temperature resistant polyurethane resin ink pattern, etc. Since various high-temperature resistant inks are existing materials, the specific components of the high-temperature resistant inks will not be introduced herein.

[0039] In this embodiment, the thickness of the high-temperature resistant ink pattern 22 is 5 - 20 μm.

[0040] Preferably, in order to improve the suspension effect of the high-temperature resistant ink pattern 22 as much as possible, the thickness of the glass substrate 21 is not less than 3 mm.

[0041] The color of the main color ink layer 23 can be, but is not limited to, one or more selected from black, white, and blue, and the back cover light-shielding ink can be, but is not limited to, a black light-shielding ink.

[0042] As Figure 2 shown, the glass substrate 21 has a display area 2a and a border area 2b. The border area 2b surrounds the display area 2a. The main color ink layer 23 and the back cover light-shielding ink layer 24 only cover the border area 2b of the glass substrate 21 and avoid the display area 2a of the glass substrate 21.

[0043] In this embodiment, the number of the high-temperature resistant ink patterns 22 is multiple, and they are spaced apart and distributed on the border area 2b of the glass substrate 21.

[0044] Embodiment Two

[0045] As Figure 3 shown, a touch screen includes a touch function layer 10 and the above-mentioned cover plate 20. The touch function layer 10 is disposed on the back surface of the cover plate 20. The cover plate 20 has at least one high-temperature resistant ink pattern 22, and the touch function layer 10 has at least one touch electrode 11. One high-temperature resistant ink pattern 22 corresponds to one touch electrode 11.

[0046] In this embodiment, the touch function layer 10 is a touch ITO layer, and is adhered to the back surface of the cover plate 20 through an OCA optical adhesive 30.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention and are not intended to limit them. Although the embodiments of the present invention have been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the embodiments of the present invention can still be modified or equivalently replaced, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
