[0030] Example 1

[0031] like Figure 1 and Figure 2As shown, the present application provides a fluorescent touch screen, comprising: a cover plate 1, having a touch display area 11 and a frame area 12, wherein a touch key area 13 is provided on the frame area 12; a cover bottom ink layer 2, wherein the cover bottom ink layer 2 is provided on the lower surface of the cover plate 1 and covers the frame area 12; a touch sensor layer 3, which is provided on the lower surface of the cover bottom ink layer 2. A reverse cover ink layer 4, wherein the reverse cover ink layer 4 covers the touch sensor layer 3 on the lower surface of the frame area 12; the cover bottom ink layer 2 and the reverse cover ink layer 4 corresponding to the lower surface of the touch key area 13 are hollowed out and a fluorescent key pattern 5 is screen-printed, and a waterproof varnish layer 6 is screen-printed on the lower surface of the fluorescent key pattern 5. The cover bottom ink layer 2 is made on the cover plate 1 by a yellow light process, and the cover bottom ink layer 2 is doped with fluorescent powder.

[0032] It should be noted that in the production of cover plates, the yellow light process is an existing technology, which is a process for making patterns or texts on glass using ultraviolet photosensitive materials. First, the photosensitive material is coated on the white glass, and a transparent template with the desired pattern or text is placed on its surface. Then, the entire glass is placed in a yellow light machine for exposure. After exposure, the glass is taken out, and the unexposed photosensitive material is washed off with a specific solvent or detergent to expose the white glass underneath. The exposed part will form a transparent layer of pattern or text. Finally, the glass is placed in a curing furnace for heating and curing, so that the transparent layer of pattern or text is firmly attached to the glass surface. Photosensitive materials doped with fluorescent powder can make the pattern appear fluorescent in a dark environment, increasing visual appeal.

[0033] In the embodiment of the present application, a cover bottom ink layer 2 is provided on the lower surface of the cover plate 1, and the cover bottom ink layer 2 is used to shield the wiring of the touch sensor layer 3. Fluorescent powder doped in the cover bottom ink layer 2 can effectively shield the wiring and have a luminous effect. Therefore, it can emit light at night or in dim light conditions, which makes it convenient for users to find devices with fluorescent touch screens at night and enhances user experience.

[0034] In the embodiment of the present application, the fluorescent key pattern 5 is surrounded by the bottom cover ink layer 2, the reverse cover ink layer 4 and the waterproof varnish layer 6 on the lower surface of the cover plate 1, which can effectively isolate the key pattern from contact with external water vapor and make the key pattern containing fluorescent powder more stable.

[0035] In a further preferred implementation of this embodiment, the bottom cover ink layer 2 is black or colored ink, so that the frame color has more diverse choices, meeting the diversified individual needs of different users and making the device more beautiful.

[0036] Example 2

[0037] like Figure 3As shown, the touch sensor layer 3 is provided with a first IM image elimination layer 31, a first ITO layer 32, a first OC layer 33, a second ITO layer 34, a metal layer 35, a second IM image elimination layer 36 and a second OC layer 37 from top to bottom, and the first IM image elimination layer 31 is plated on the bottom cover ink layer 2.

[0038] In this embodiment, the first IM shadow elimination layer 31 is firstly coated on the bottom cover ink layer 2 by vacuum coating, and then the first ITO layer 32, the first OC layer 33, the second ITO layer 34, the metal layer 35, the second IM shadow elimination layer 36, and finally the second OC layer 37 are coated in sequence. By combining the first IM shadow elimination layer 31 and the second IM shadow elimination layer 36 and adjusting the reflectivity of the shadow elimination layer, the reflectivity of the frame area 12 and the touch display area 11 can be made close to the same, thereby achieving an integrated black effect.

[0039] It should be noted that the composition of the IM erasing layer is Si3Nx / SiOx, which is a composite material composed of silicon nitride and silicon dioxide, and has many excellent properties. Among them, silicon nitride has the characteristics of high hardness, high strength, high heat resistance and high corrosion resistance, while silicon dioxide has excellent optical properties and chemical stability. The preparation method of this composite material generally adopts chemical vapor deposition CVD or physical vapor deposition PVD and other technologies.

[0040] Si3Nx / SiOx has a wide range of applications in optical applications, the most common of which is the production of anti-shadow, integrated black and other products. Anti-shadow refers to the production of a layer of film with extremely low reflectivity on the surface of the optical element to eliminate the reflection on the surface of the optical element and improve the transmittance and clarity. Integrated black refers to the coating of the edge and back of the optical element with a black film layer to achieve the effect of eliminating reflection and improving contrast. In these applications, Si3Nx / SiOx is mainly used to produce films with low reflectivity and high transmittance, thereby achieving the effect of eliminating reflection and improving transmittance.

[0041] Furthermore, the touch sensor layer 3 covers the touch display area 11, and the touch button area 13 does not need to be additionally designed with a circuit. The fluorescent material can automatically emit light at night, display ink color during the day, and display fluorescent color at night.

[0042] In another preferred solution of this embodiment, the touch sensor layer 3 covers the touch key area 13 so as to realize the corresponding key function.

[0043] Example 3

[0044] The fluorescent touch screen provided in Example 1 is further optimized, wherein the fluorescent key pattern 5 is a white silk-screen pattern, and the transmittance of the fluorescent key pattern 5 is 0.5%-2%.

[0045] The transmittance of the fluorescent key pattern 5 is 0.5%-2%, which means that under dim light conditions, the fluorescent key pattern 5 will emit a weak fluorescent light, thereby providing a certain lighting effect at night or in a dim light environment. This design allows users to find the touch screen device more easily at night without causing too much glare. In addition, the fluorescent key pattern 5 with a white silk-screen pattern will be displayed as white during the day, and will emit a weak fluorescence at night or in dim light conditions. While maintaining the white appearance, it can provide a nighttime lighting effect, which is very in line with the actual needs of users for touch screen devices.

[0046] In this embodiment, the reverse cover ink layer 4 is black ink, which can protect the touch sensor layer 3 on the first cover bottom ink layer 2 .

[0047] Further, the cover plate 1 is a glass cover plate 1, a plastic cover plate 1 or a flexible film cover plate 1. Among them, the glass cover plate has high reliability and mature technology, the plastic cover plate is relatively cheap, and the flexible film cover plate can be bent and deformed at will, all of which have their own advantages.

[0048] Example 4

[0049] The utility model also provides an electronic device, having a fluorescent touch screen provided by the above utility model embodiment, comprising: a cover plate 1, having a touch display area 11 and a frame area 12, wherein a touch key area 13 is provided on the frame area 12; a cover bottom ink layer 2, wherein the cover bottom ink layer 2 is provided on the lower surface of the cover plate 1 and covers the frame area 12; a touch sensor layer 3, which is provided on the lower surface of the cover bottom ink layer 2. A reverse cover ink layer 4, wherein the reverse cover ink layer 4 covers the touch sensor layer 3 on the lower surface of the frame area 12; the touch key area 13 corresponds to the lower surface of the cover bottom ink layer 2 and the reverse cover ink layer 4, and a fluorescent key pattern 5 is screen-printed, and a waterproof varnish layer 6 is screen-printed on the lower surface of the fluorescent key pattern 5. The present application can emit light at night or in dim light conditions through the silk-screened fluorescent pattern. The fluorescent material can automatically emit light at night without the need for additional circuit design. It displays the ink color during the day and the fluorescent color at night, which is convenient for users to find devices with fluorescent touch screens at night and enhances the user experience. In addition, waterproof varnish is provided under the silk-screen pattern to isolate the key pattern from contact with external water vapor, thereby making the key pattern containing fluorescent powder more stable.
