[0021] In order to enable those skilled in the art to better understand the solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] As used herein, the term "one embodiment" or "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation manner of the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. Moreover, the terms "first", "second", etc. are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein.

[0023] To solve the above problems, the present utility model discloses a ten-inch screen with virtual keys. Specifically, asFigure 1 As shown in the figure, the ten-inch screen with virtual keys includes a cover glass 1, a touch layer 2, and a display screen 3. The cover glass 1 is adhered to the touch layer 2 with a first optical adhesive 4, and the touch layer 2 is adhered to the display screen 3 with a second optical adhesive 5. The substrate of the touch layer 2 is a PET film substrate 6. A virtual key area 8 is set at the edge position of the screen. The virtual key area 8 is in a strip shape and the long side edge is flush with the short side edge of the touch layer.

[0024] In one example, the cover glass 1 is cut from a large piece of glass. First, the front and back sides of the cut large piece of glass are pasted with films, and then the edges are corroded with strong acid to make the edges smooth. Finally, it is chemically strengthened to form the cover glass 1. The cover glass 1 is adhered to the touch layer 2 through the first optical adhesive 4, and the touch layer 2 is adhered to the bottom display screen 3 through the second optical adhesive 5. By using optical adhesives for layer-by-layer adhesion, the air layer between the three-layer structure of the cover glass 1, the touch layer 2, and the display screen 3 is fully compressed, reducing the thickness of the screen.

[0025] Refer to Figure 3 , the touch layer 2 is composed of a PET film substrate 6 and a thin film sensor 7. The thin film sensor 7 is respectively coated on the upper and lower surfaces of the PET film substrate 6 through an optical adhesive. By using the PET film substrate 6 to replace the glass substrate in the traditional technology for the substrate of the touch layer 2, the thickness of the screen is greatly reduced.

[0026] Furthermore, the thin film sensor 7 is an indium tin oxide semiconductor transparent conductive film; the thin film sensor 7 is made by using a yellow light process or laser, that is, the part left after exposure and development of the photosensitive substance coated on the PET film substrate 6 plays a protective role for the bottom layer, and is made after etching and demolding.

[0027] Furthermore, the adhesive between the thin film sensor 7 and the PET film substrate 6 is an OCA optical adhesive;

[0028] Furthermore, the first optical adhesive 4 and the second optical adhesive 5 are OCA optical adhesives;

[0029] Using OCA optical adhesives to replace the traditional mouth-shaped adhesives enables seamless bonding between the PET film substrate 6 and the two-sided thin film sensors 7, the glass cover 1 and the touch layer 2, and the touch layer 2 and the display screen 3. The screen is thinner and lighter, and has better sealing performance;

[0030] The second optical adhesive 5 can be replaced by a water-based adhesive.

[0031] Furthermore, a virtual key area 8 is set at the edge of the screen. By using virtual keys to replace traditional physical keys, the problem of the lifespan of physical mechanical keys is solved, and problems such as gaps existing in physical keys, which are prone to ingress of debris, dust, and water and are easily contaminated and damaged, are eliminated. The long-edge edge of the virtual key area is flush with the short-edge edge of the touch layer, extending the length of the visible area edge, facilitating the later expansion of the virtual key area and improving the consistency of the overall appearance of the machine. It also improves the problem that the traditional touch screen occupies the screen display space through UI control. In a preferred example, the inner edge of the virtual key area is 15 mm away from the short-edge of the screen, and the width of the effective touch area is 10 mm.

[0032] The disclosed ten-inch screen with virtual keys of the present utility model includes a cover glass 1, a touch layer 2, and a display screen 3. The cover glass 1 and the touch layer 2 are pasted with a first optical adhesive 4, and the touch layer 2 and the display screen 3 are pasted with a second optical adhesive 5. The substrate of the touch layer 2 is a PET film substrate 6. A virtual key area 8 is set at the edge position of the screen. The virtual key area 8 is a strip-shaped structure and its long-edge edge is flush with the short-edge edge of the touch layer. The cover glass 1 is cut from a large piece of glass. First, its front and back surfaces are pasted with films, then the edge serrations are etched with strong acid, and finally, it is chemically strengthened to form the cover glass 1. The touch layer 2 is a PET film substrate 6 with thin film sensors 7 loaded on both the upper and lower surfaces. The thin film sensor 7 is an indium tin oxide semiconductor transparent conductive film, and the thin film sensor 7 is made by a yellow light process or laser. The thin film sensor 7 is bonded to the PET film substrate 6 with an adhesive. The adhesive between the thin film sensor 7 and the PET film substrate 6 is an OCA optical adhesive. The first optical adhesive 4 and the second optical adhesive 5 are OCA optical adhesives. The second optical adhesive 5 can be replaced by a water-based adhesive. The virtual key area 8 is set at the edge part on one side of the short edge of the screen. At the virtual key area 8, key light-emitting areas are arranged at equal intervals, and the cover glass corresponding to the key light-emitting areas is a hollow structure.
