[0023] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model.

[0025] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0026] The utility model provides a wearable AMOLED liquid crystal display screen with improved antistatic ability, comprising an AMOLED screen glass, a cover plate is arranged above the AMOLED screen glass, foam glue is arranged below the AMOLED screen glass, the foam glue is arranged with an indented portion at the edge of the AMOLED screen glass, a conductive glue frame is arranged at the indented portion, and the conductive glue frame is arranged around the foam glue.

[0027] Since the foam glue is provided with a retracted portion at the edge of the AMOLED screen glass, a conductive glue frame is provided at the retracted portion, and the conductive glue frame is provided around the foam glue, so that the outermost layer of the foam glue is surrounded and wrapped by the conductive glue frame, and the conductive glue frame is very close to the edge of the AMOLED screen glass, when the whole machine is subjected to static electricity testing or static electricity attack during use, the static electricity will be preferentially conducted to the conductive glue frame, thereby protecting the AMOLED liquid crystal display and circuits from damage, improving the anti-static ability of the AMOLED liquid crystal display, and thereby reducing the defective rate of the AMOLED liquid crystal display, and improving the competitiveness of the product.

[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] Example 1

[0030] See also Figure 1 , a wearable AMOLED liquid crystal display screen with improved anti-static ability provided by the utility model, comprising an AMOLED screen glass 1, a cover plate 2 is arranged above the AMOLED screen glass 1, a foam glue 3 is arranged below the AMOLED screen glass 1, the foam glue 3 is provided with an indentation at the edge of the AMOLED screen glass 1, a conductive glue frame 4 is arranged at the indentation, and the conductive glue frame 4 is arranged around the foam glue 3. Since the foam glue 3 is provided with an indentation at the edge of the AMOLED screen glass 1, the conductive glue frame 4 is arranged at the indentation, and the conductive glue frame 4 is arranged around the foam glue 3, the outermost layer of the foam glue 3 is surrounded and wrapped by the conductive glue frame 4, and the conductive glue frame 4 is very close to the edge of the AMOLED screen glass 1. When the whole machine is subjected to static electricity attack during static electricity test or use, static electricity will be preferentially conducted to the conductive glue frame 4, protecting the AMOLED liquid crystal display screen and the circuit from being damaged, improving the anti-static ability of the AMOLED liquid crystal display screen, thereby reducing the defective rate of the AMOLED liquid crystal display screen and improving the competitiveness of the product.

[0031] Furthermore, an FPC is provided on the AMOLED screen glass 1 , and the FPC is provided with a grounding wire, which is electrically connected to the conductive rubber frame 4 , so that static electricity on the conductive rubber frame 4 can be conducted out through the grounding wire on the FPC.

[0032] Furthermore, the outer edge of the conductive plastic frame 4 exceeds the outer edge of the AMOLED screen glass 1 , so that static electricity is preferentially transferred to the conductive plastic frame 4 , thereby avoiding damage to the AMOLED screen glass 1 .

[0033] Example 2

[0034] See also Figure 2 As a further optimization scheme of Example 1, in this embodiment, an anti-fall plate 5 is provided above the cover plate 2, and an ink layer 51 is provided on the lower surface of the anti-fall plate 5 located in the non-visible area. The cover plate 2 and the anti-fall plate 5 are fixed by an adhesive layer 52, and the adhesive layer 52 completely covers the ink layer 51 and the lower surface of the anti-fall plate 5. Since there is another layer of anti-fall plate 5 above the cover plate 2, and the adhesive layer 52 is printed on the entire surface of the back of the anti-fall plate 5, it covers the ink layer 51 in the non-visible area and the lower surface of the anti-fall plate 5 in the visible area, fills the ink step difference, and does not cause the phenomenon of laminating bubbles and edge yellow spots. The cover plate 2 can be fully laminated with the upper polarizer through liquid optical glue. Since the cover plate 2 is not provided with an ink layer 51, it will not cause the phenomenon of laminating bubbles and edge yellow spots, thereby avoiding the display abnormality of the AMOLED screen glass 1, thereby reducing the probability of defective products of the AMOLED screen glass 1, and the production and manufacturing costs of the AMOLED screen glass 1 will also be greatly reduced.

[0035] And when the anti-fall plate 5 is impacted by external force, the anti-fall plate 5 will break first. Due to the buffering effect of the adhesive layer 52, the cover plate 2 is not easy to break, so the cover plate 2 and the main screen can be well protected. When the anti-fall plate 5 is broken, the anti-fall plate 5 can be easily peeled off, and only a new anti-fall plate 5 needs to be replaced. There is no need to replace the entire AMOLED screen glass 1, thereby greatly reducing the maintenance cost of the AMOLED screen glass 1, and then improving the product competitiveness of the AMOLED screen glass 1, so as to meet the company's growing quality requirements.

[0036] Further, the thickness of the ink layer 51 is 8 μm to 15 μm.

[0037] Furthermore, the thickness of the adhesive layer 52 is 50 μm.

[0038] Furthermore, the thickness of the anti-fall plate 5 is 5 mm to 10 mm, and the thickness of the cover plate 2 is 3 mm to 5 mm.

[0039] Furthermore, the upper surface of the anti-fall plate 5 is covered with an anti-fingerprint film layer to prevent user fingerprints from remaining on the anti-fall plate 5 and enhance the aesthetics.

[0040] 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.

[0041] Furthermore, the hardness of the anti-fall plate 5 is greater than the hardness of the cover plate 2 to enhance the protection effect.

[0042] 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.

[0043] 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.
