Therefore, the characteristic that the AG anti-dazzle layer can form the AG anti-dazzle particles arranged at intervals on the cover plate body can be utilized, and the thickness of the exposure ink layer is smaller than that of the AG anti-dazzle layer, so that the exposure ink layer can enter gaps among the AG anti-dazzle particles, and meanwhile, the AG anti-dazzle particles are utilized to transmit light, so that the exposure ink layer is prevented from entering gaps among the AG anti-dazzle particles. The light transmittance of the cover plate body is changed due to the light-proof characteristic of the exposure ink layer, so that an existing smoked OCA or smoked optical film scheme can be replaced, and the integrated black effect of the touch screen is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of touch screens, in particular to a smoked cover plate structure and a touch screen. Background Art

[0002] With the rapid development of science and technology, touch screen technology has been widely used in various electronic devices, such as smart phones, tablet computers, smart watches, etc. In order to make the appearance of the touch screen more technological and advanced, touch screen manufacturers usually add a black requirement to the cover plate and touch screen design of the touch screen, that is, when the screen is off, the color of the cover plate and the touch screen viewing area must be consistent with the color of the surrounding masking ink.

[0003] However, the conventional way to achieve the integrated black effect is to add smoked OCA or smoked optical film to the touch screen instead of transparent OCA or optical film. The transmittance will be restricted by the raw materials. When making smoked OCA and optical film, the process deviation will also cause uneven transmittance in the same batch.

[0004] In view of the above, a smoked cover plate structure and a touch screen are proposed to replace the existing smoked OCA or smoked optical film solutions to achieve an integrated black effect of the touch screen. Utility Model Content

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] See also Figure 2 , Figure 3 and Figure 4 As shown, a smoked cover structure 10 includes: a cover body 100, an AG anti-glare layer 200 and an exposure ink layer 300, the cover body 100 has a cover front and a cover back, the AG anti-glare layer 200 is arranged on the back of the cover, the exposure ink layer 300 is arranged on the AG anti-glare layer 200, and the thickness of the exposure ink layer 300 is less than the thickness of the AG anti-glare layer 200.

[0026] It should be noted that, the AG anti-glare layer 200 is a light-transmitting layer, the exposure ink layer 300 is an opaque layer, and the AG (Anti-Glare) anti-glare layer 300 is composed of AG anti-glare particles. Since a gap is formed between each AG anti-glare particle, and then a layer of exposure ink layer 300 is arranged on the AG anti-glare layer 200, and the thickness of the exposure ink layer 300 is made smaller than the thickness of the AG anti-glare layer 200, then the exposure ink layer 300 covering the AG anti-glare layer 200 will flow into the gap between the AG anti-glare particles, that is, at this time, the AG anti-glare layer 200 The anti-glare particles are equivalent to forming a plurality of spaced bosses on the cover body 100, and then spraying a layer of exposure ink. Since the thickness of the exposure ink is smaller than that of the AG anti-glare layer 200, the exposure ink covering the AG anti-glare particles will flow along the AG anti-glare particles to the gaps between the AG anti-glare particles. In this way, the area with the AG anti-glare particles forms a light-transmitting area, and the area with the exposure ink layer 300 forms an opaque area. In this way, the light transmittance of the cover body can be changed to form a smoked cover. In this way, the existing smoked OCA (Optically Clear Adhesive) or smoked optical film solution can be replaced to achieve the integrated black effect of the touch screen. In addition, since the cover is uniformly processed on the large glass plate to form the AG anti-glare layer and the exposure ink layer, and then cut into single particles, the transmittance consistency of the smoked cover in the same batch can also be ensured.

[0027] Furthermore, it should be noted that the AG anti-glare layer 200 can be formed by spraying or etching, and then a layer of exposure ink is sprayed or screen-printed on the side of the cover body 100 with the AG anti-glare layer 200 by yellow light process technology. In addition, the transmittance of the smoked cover structure can be adjusted by controlling the size of the AG anti-glare particles in the AG anti-glare layer and the spacing between the AG anti-glare particles.

[0028] Preferably, the thickness of the AG anti-glare layer 200 is 10 μm, that is, the thickness of the AG anti-glare particles therein is 10 μm, and at the same time, the thickness of the AG anti-glare layer 200 is greater than the thickness of the exposure ink layer 300, so in this embodiment, preferably, the thickness of the exposure ink layer is 1.5 μm.

[0029] Preferably, the cover body 100 is a glass cover.

[0030] Preferably, the thickness of the glass cover plate is 1.3 mm.

[0031] In one embodiment, the smoked cover plate structure 10 further includes a reverse cover ink layer 400. The cover plate body 100 is provided with a frame area and a display area. The frame area is provided around the four peripheries of the display area. The reverse cover ink layer 400 is provided on the frame area, and the reverse cover ink layer 400 is provided on the back of the cover plate. Preferably, the reverse cover ink layer 400 is a black ink layer. The reverse cover ink layer 400 serves as a light shielding decoration and covers the metal wiring layer area in the touch screen to prevent the naked eye from seeing the metal wiring layer in the touch screen through the smoked cover plate. The thickness of the reverse cover ink layer is 15 μm, so that it can be ensured that the reverse cover ink layer can cover the AG anti-glare ink layer 300.

[0032] Furthermore, in order to prevent the AG anti-glare layer 200 and the exposure ink layer from being scratched during the production process, a silicon dioxide protective layer may be covered on the entire back surface of the cover plate of the cover plate body.

[0033] A touch screen includes the smoked cover plate structure 10 and a touch sensing structure 20, wherein the touch sensing structure 20 is attached to the back of the smoked cover plate structure 10. The touch sensing function of the touch screen is realized by the touch sensing structure 20. For example, preferably, the touch sensing structure 20 is attached to the back of the smoked cover plate structure 10 by OCA optical adhesive 20a, and the OCA optical adhesive has high light transmittance, so the display effect of the touch screen can be ensured.

[0034] Furthermore, the touch sensing structure 20 includes a touch sensing glass 20b, an ITO (indium tin oxide) pattern layer 20c is formed on the touch sensing glass, a metal wiring layer 20d is arranged around the four peripheries of the ITO pattern layer 20c, and the metal wiring layer 20d is connected to the ITO pattern layer 20c. For example, the metal wiring layer is a molybdenum metal wiring layer, and a flexible circuit board is bound to the metal wiring layer, thereby realizing the touch sensing function.

[0035] Furthermore, in order to prevent the metal wiring layer from being scratched during the production process, the metal wiring layer may be covered with an insulating protection layer 20e, such as an insulating resin layer, so as to isolate and protect the metal wiring layer.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
