[0026] The utility model provides a liquid crystal screen that solves the problem of micro-breaks in silver paste routing, comprising a touch substrate, a first ITO layer, a second ITO layer, a first silver paste routing, a second silver paste routing, a first FPC, a second FPC, a first insulating oil and a second insulating oil, wherein the first ITO layer is arranged on the upper surface of the touch substrate and covers a visible area and a non-visual area; the second ITO layer is arranged on the lower surface of the touch substrate and covers a visible area and a non-visual area; the first silver paste routing is arranged on the edge of the upper surface of the first ITO layer and is located in the non-visual area; the second silver paste routing is arranged on the edge of the lower surface of the second ITO layer and is located in the non-visual area; the first FPC is arranged on the upper surface of one end of the first silver paste routing; the second FPC is arranged on the lower surface of one end of the second silver paste routing; the first insulating oil covers the upper surface of the first silver paste routing; the second insulating oil covers the lower surface of the second silver paste routing.
[0027] Since the first ITO layer and the second ITO layer both cover the visible area and the non-visible area of the touch substrate, and the first silver paste routing and the second silver paste routing respectively cover the non-visible areas of the first ITO layer and the second ITO layer, that is, the first silver paste routing and the second silver paste routing are respectively primed by the first ITO layer and the second ITO layer, so that the contact area between the first silver paste routing and the second silver paste routing and the first ITO layer and the second ITO layer is increased, even if the first silver paste routing or the second silver paste routing is slightly broken, the first ITO layer and the second ITO layer can make up for the slight break, thereby avoiding failure of the touch function, controlling product quality, and improving product competitiveness; and the manufacturing process remains unchanged, and the product performance is increased while the price does not increase.
[0028] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.
[0029] See also Figure 1, a liquid crystal screen for solving the problem of micro-breaks in silver paste routing provided by the utility model, comprising a touch substrate 1, a first ITO layer 2, a second ITO layer 3, a first silver paste routing 4, a second silver paste routing 5, a first FPC 6, a second FPC 7, a first insulating oil 8 and a second insulating oil 9, the first ITO layer 2 is arranged on the upper surface of the touch substrate 1 and covers the visible area and the non-visible area; the second ITO layer 3 is arranged on the lower surface of the touch substrate 1 and covers the visible area and the non-visible area; the first silver paste routing 4 is arranged on the edge of the upper surface of the first ITO layer 2 and is located in the non-visible area; the second silver paste routing 5 is arranged on the edge of the lower surface of the second ITO layer 3 and is located in the non-visible area; the first FPC 6 is arranged on the upper surface of one end of the first silver paste routing 4; the second FPC 7 is arranged on the lower surface of one end of the second silver paste routing 5; the first insulating oil 8 covers the upper surface of the first silver paste routing 4; the second insulating oil 9 covers the lower surface of the second silver paste routing 5. Since the first ITO layer 2 and the second ITO layer 3 both cover the visible area and the non-visible area of the touch substrate 1, and the first silver paste routing 4 and the second silver paste routing 5 respectively cover the non-visible areas of the first ITO layer 2 and the second ITO layer 3, that is, the first silver paste routing 4 and the second silver paste routing 5 are respectively primed by the first ITO layer 2 and the second ITO layer 3, so that the contact area between the first silver paste routing 4 and the second silver paste routing 5 and the first ITO layer 2 and the second ITO layer 3 is increased. Even if the first silver paste routing 4 or the second silver paste routing 5 is slightly broken, the first ITO layer 2 and the second ITO layer 3 can make up for the slight break, thereby avoiding failure of the touch function, controlling product quality, and improving product competitiveness; and the manufacturing process remains unchanged, and the product performance is increased while the price does not increase.
[0030] Furthermore, the first ITO layer 2 extends to the edge of the upper surface of the touch substrate 1, and the second ITO layer 3 extends to the edge of the lower surface of the touch substrate 1, so as to increase the contact area between the first ITO layer 2 and the second ITO layer 3 and the first silver paste wiring 4 and the second silver paste wiring 5, and solve the problem of micro-breaks in the silver paste wiring.
[0031] See also Figure 2As a further optimization scheme of Example 1, in this embodiment, a cover plate 10 is arranged above the touch substrate 1, and an anti-fall plate 11 is arranged above the cover plate 10. An ink layer 12 is arranged on the lower surface of the anti-fall plate 11 located in the non-visible area. The cover plate 10 and the anti-fall plate 11 are fixed by an adhesive layer 13. The adhesive layer 13 completely covers the ink layer 12 and the lower surface of the anti-fall plate 11. The cover plate 10 and the touch substrate 1 are fully bonded by optical glue 14. Since there is an anti-fall plate 11 on the cover plate 10, and the adhesive layer 13 is printed entirely on the back of the anti-fall plate 11, it covers the ink layer 12 in the non-visible area and the lower surface of the anti-fall plate 11 in the visible area, fills the ink step difference, and does not cause the phenomenon of bonding bubbles and edge yellow spots. The cover plate 10 can be fully bonded to the touch substrate 1 through the optical glue 14. Since the cover plate 10 is not provided with an ink layer 12, it will not cause the phenomenon of bonding bubbles and edge yellow spots, thereby avoiding display abnormalities of the liquid crystal display module, thereby reducing the probability of defective products in the liquid crystal display module, and greatly reducing the production and manufacturing costs of the liquid crystal display module.
[0032] And when the anti-fall plate 11 is impacted by external force, the anti-fall plate 11 will break first. Due to the buffering effect of the adhesive layer 13, the cover plate 10 is not easy to break, so the cover plate 10 and the main screen can be well protected. When the anti-fall plate 11 is broken, the anti-fall plate 11 can be easily peeled off, and only a new anti-fall plate 11 needs to be replaced. There is no need to replace the entire LCD display module, thereby greatly reducing the maintenance cost of the LCD display module, thereby improving the product competitiveness of the LCD display module, so as to meet the company's growing quality requirements.
[0033] Furthermore, the thickness of the ink layer 12 is 8 μm to 15 μm.
[0034] Furthermore, the thickness of the adhesive layer 13 is 50 μm.
[0035] Furthermore, the thickness of the anti-fall plate 11 is 5 mm to 10 mm, and the thickness of the cover plate 10 is 3 mm to 5 mm.
[0036] Furthermore, the upper surface of the anti-fall plate 11 is covered with an anti-fingerprint film layer to prevent user fingerprints from remaining on the anti-fall plate 11 and enhance the aesthetics.
[0037] Furthermore, a color conversion layer is provided on the upper surface of the anti-fingerprint film layer located in the non-display area to further enhance the aesthetics of the product.
[0038] Furthermore, the hardness of the anti-fall plate 11 is greater than the hardness of the cover plate 10 to enhance the protection effect.
[0039] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0040] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.
