[0031] Embodiment 1

[0032] like Figure 1As shown, a touch display screen includes a glass panel 1, wherein a first moth-eye micro-nano structure 101 is provided on the lower surface of the glass panel 1;

[0033] Transparent glass 3, disposed on the lower surface of the glass panel, and a second moth-eye micro-nano structure 301 is disposed on the upper surface of the transparent glass 3;

[0034] A touch function layer 32, wherein the touch function layer 32 is located on the lower surface of the transparent glass 3;

[0035] The display screen 5 is disposed on the lower surface of the touch function layer 32 .

[0036] The moth-eye micro-nano structure used in the embodiment of the utility model is a surface nano-scale protrusion array, which is a bionic product that imitates the fine concave-convex structure in the eyes of moths. When the sub-micrometer structure size on the surface of the material is smaller than the wavelength of visible light, the light wave will not be able to recognize the microstructure, so the refractive index on the surface of the material changes continuously along the depth direction, which can reduce the reflection phenomenon caused by the sharp change of the refractive index. The utility model sets the moth-eye micro-nano structure on the surface of the glass panel 1 and the transparent glass 3, so that there will be no interface with significantly different refractive index, thereby achieving the purpose of preventing reflection, so that the refractive index between the glass panel 1 and the touch function layer 32 changes continuously along the depth direction, significantly reducing the screen surface reflection phenomenon caused by the sharp change of the refractive index, and finally reducing the reflection phenomenon of the entire screen. Compared with the prior art, the utility model can significantly improve the anti-reflection effect of the touch display screen, enhance the contrast of the display screen, and thus improve the display effect of the display screen.

[0037] In this embodiment, the first moth-eye micro-nano structure 101 and the second moth-eye micro-nano structure 301 are nanoscale protrusion arrays.

[0038] Furthermore, the touch screen of the utility model further comprises a first adhesive layer 2 and a second adhesive layer 4, wherein the first adhesive layer 2 is PVB adhesive; the second adhesive layer 4 is OCA adhesive;

[0039] The transparent glass 3 is bonded to the glass panel 1 through the first adhesive layer 2;

[0040] The display screen 5 is bonded to the touch function layer 32 via the second adhesive layer 4 .

[0041] It should be noted that PVB glue is a polyvinyl alcohol acrylate copolymer with excellent impact resistance and bonding properties. In this touch display screen, PVB glue as the first glue layer 2 can effectively absorb and disperse impact force, thereby improving the impact resistance of the display screen. At the same time, PVB glue can also effectively bond transparent glass and glass panels to form a solid structure, thereby improving the stability and durability of the display screen. The touch function layer 32 is located on the lower surface of the transparent glass 3, which can realize the touch function, and the second glue layer 4 and the display screen 5 are located below the touch function layer, which can display images and information.

[0042] The bonding principle of PVB glue and glass: the hydrogen bonds between SiOH in the glass and COH groups in PVB glue form bonding force, so it has better bonding ability than ordinary OCA / OCR, and there will be no glass shattering in the collision.

[0043] like Figure 4 As shown, in this embodiment, the upper surface of the glass panel 1 is provided with an anti-glare micro-nano structure 11. The anti-glare micro-nano structure 11 is formed on the upper surface of the glass panel 1 by micro-machining technology. It should be noted that the processing method of the anti-glare micro-nano structure 11 is a prior art, which refers to the process of converting an image or texture into an anti-glare micro-nano structure by digital technology. When making the anti-glare micro-nano structure, micro-machining technologies such as electron beam, holographic technology, laser writing, ultra-precision machining technology, electrochemistry, etc. can be used to achieve it. These machining technologies can convert digital image or texture information into tiny concave-convex structures, and the size of these structures is usually at the micron or nanometer level. By adjusting the parameters such as the shape, size, and distribution of these structures, different optical effects can be achieved. For example, by electron beam or laser writing technology, tiny pits or protrusions can be made on the glass panel 1. These structures can change the refraction, reflection and scattering of light, thereby presenting different optical effects. Holographic technology can use the interference principle to create complex optical textures on the glass panel 1 to achieve a more three-dimensional and vivid effect. In conclusion, through these micro-machining technologies, an anti-glare micro-nano structure can be formed on the surface of the glass panel 1, thereby achieving various optical effects.

[0044] The anti-glare micro-nano structure 11 in the utility model can reduce the glare on the glass surface. Furthermore, the edges of the transparent glass 3 facing the glass panel 1 are provided with black ink 31. The anti-glare micro-nano structure 11 cooperates with the first moth-eye micro-nano structure and the second moth-eye micro-nano structure to make the screen display area 312 darker and blacker in the screen-off state, thereby achieving a better screen-off integrated black effect.

[0045] like Figure 2As shown, the area enclosed by the black ink 31 is the screen display area 312 , and the area covered by the black ink 31 is the non-display area 311 .

[0046] In this embodiment, the black ink 31 is printed on the surface of the transparent glass 3 by silk screen printing technology or UV transfer technology.

[0050] In this embodiment, the transparent glass 3 is the outer layer of the touch screen, through which touch operations can be implemented. The touch function layer 32 is a layer located below the transparent glass 3 and is used to detect touch operations. The touch function layer 32 adopts an ITO bridge touch pattern, which can improve the sensitivity and accuracy of the touch screen. The metal trace 33 is located on the periphery of the touch function layer 32 and overlaps the touch function layer 32. The metal trace 33 adopts a molybdenum metal trace.

After the metal trace 33 is bound to FPC7, it can be connected to the mainboard, thereby realizing the control and data transmission of the touch screen.

[0051] It should be noted that the ITO bridge touch pattern refers to a touch pattern made using ITO indium tin oxide material on colorless transparent glass. ITO is a transparent conductive material that can be used to make touch screens. In the ITO bridge touch pattern, the ITO material is made into some small bridges that connect different areas in the touch pattern together to form a complete circuit. When the user touches the screen, the ITO material senses the touch signal and transmits the signal to the circuit, thereby realizing the touch operation.

[0052] In another preferred embodiment of the present invention, the metal trace 33 is electrically connected to the FPC 7 via an ACF, wherein the ACF is a conductive tape used to bind the ITO bridge touch pattern to the FPC. The ACF is conductive and can establish an electrical connection between the ITO pattern and the FPC 7.

[0053] In this embodiment, the molybdenum traces are overlapped with the ITO bridge touch pattern, and then they are bound together with FPC7 using ACF. ACF tape generally has high temperature and high pressure bonding properties, which can ensure a stable electrical connection. Through the binding of ACF and FPC7, the touch signal of the ITO pattern can be transmitted to FPC7, and then connected to other circuits or processors to achieve touch function; it should be noted that during the binding process, the alignment and bonding quality between ACF and FPC7 need to be ensured to ensure a reliable electrical connection.

[0054] In this embodiment, the second adhesive layer 4 uses OCA optical adhesive to bond the display screen 5, and a backlight assembly 6 is provided on the lower surface of the display screen 5; OCA optical adhesive is a transparent adhesive with good optical properties, which can ensure the close bonding between the display screen 5 and the second adhesive layer 4, thereby improving the display effect and viewing experience; at the same time, a backlight assembly 6 is provided on the lower surface of the display screen 5; the backlight assembly 6 is a device that provides backlight illumination, which can enable the display screen 5 to still display clear images and text in a dark environment; the backlight assembly 6 can use a light source such as LED, and through the reflection and conduction of light, the image on the display screen 5 can be seen by the observer.

[0055] By using OCA optical adhesive to bond the display screen 5 and providing the backlight assembly 6, this embodiment can achieve high-quality display and backlight illumination of the display screen, thereby improving the viewing experience.

[0056] The display screen 5 is a TFT liquid crystal display screen. The TFT liquid crystal display screen is a common flat display technology. It controls the light transmittance of liquid crystal by adding a thin film transistor to each pixel point, thereby realizing image display. The TFT liquid crystal display screen has the characteristics of excellent color reproduction ability, high contrast, fast response time and wide viewing angle. By adopting the TFT liquid crystal display screen, this embodiment can achieve high-definition and delicate image display effects and provide a better visual experience.

[0057] In another preferred embodiment of this embodiment, Figure 3 As shown, the display screen 5 and the backlight assembly 6 are replaced by a self-luminous screen 8, and the self-luminous screen 8 is OLED or miniLED;

[0058] Among them, self-luminous OLED is a new type of flat display technology, which uses organic materials as light-emitting materials and realizes image display by adding light-emitting diodes to each pixel. Self-luminous OLED has the characteristics of high contrast, fast response time, wide viewing angle, low power consumption, etc., and can also achieve more delicate and realistic color performance; miniLED is a new type of backlight technology, which uses tiny LED chips as light sources and realizes backlighting through the combination of thousands of tiny LED chips.
