[0024] 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. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] 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.

[0027] The utility model provides a double-screen display screen for preventing display abnormality, which comprises a cover plate, a TN screen, an STN screen, optical glue and a frame-type double-sided adhesive, wherein the TN screen is arranged on the left side below the cover plate; the STN screen is arranged on the right side below the cover plate; the optical glue is arranged on the TN screen, and the TN screen is adhered to the cover plate through the optical glue; the frame-type double-sided adhesive is arranged on the non-display area of ​​the STN screen, and the STN screen is adhered and fixed to the cover plate through the frame-type double-sided adhesive.

[0028] Since the STN screen and the cover plate are fixed with frame-type double-sided adhesive, and the frame-type double-sided adhesive is set in the non-display area of ​​the STN screen, when the cover plate is pressed by a finger, the pressure transmitted from the cover plate will be absorbed by the frame-type double-sided adhesive, so that the pressure will not be transmitted to the STN screen, allowing the STN screen to display normally, avoiding abnormal display of the STN screen when pressed by a finger, thereby improving user experience and increasing product competitiveness.

[0029] 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.

[0030] See also Figures 1 to 3 , a dual-screen display screen for preventing display abnormality provided by the utility model, comprising a cover plate 1, a TN screen 2, an STN screen 3, an optical glue 4 and a frame-type double-sided adhesive 5, wherein the TN screen 2 is arranged on the left side below the cover plate 1; the STN screen 3 is arranged on the right side below the cover plate 1; the optical glue 4 is arranged on the TN screen 2, and the TN screen 2 is bonded to the cover plate 1 through the optical glue 4; the frame-type double-sided adhesive 5 is arranged on the non-display area of ​​the STN screen 3, and the STN screen 3 is bonded and fixed to the cover plate 1 through the frame-type double-sided adhesive 5. Since the STN screen 3 is bonded and fixed to the cover plate 1 by the frame-type double-sided adhesive 5, and the frame-type double-sided adhesive 5 is arranged in the non-display area of ​​the STN screen 3, when a finger presses the cover plate 1, the pressure transmitted from the cover plate 1 will be absorbed by the frame-type double-sided adhesive 5, so that the pressure will not be transmitted to the STN screen 3, so that the STN screen 3 can display normally, and avoid the abnormal display of the STN screen 3 when being pressed by a finger, thereby improving the user experience and the competitiveness of the product.

[0031] Furthermore, the frame-shaped double-sided adhesive 5 is a foam double-sided adhesive, which has a strong ability to absorb pressure, and can further ensure the normal display of the STN screen 3.

[0032] Furthermore, the optical glue 4 is solid glue.

[0033] See also Figure 4As a further optimization scheme of Example 1, in this embodiment, an anti-fall plate 6 is provided on the top of the cover plate 1, and an ink layer 7 is provided on the lower surface of the anti-fall plate 6 located in the non-visible area. The cover plate 1 and the anti-fall plate 6 are fixed by an adhesive layer 8, and the adhesive layer 8 completely covers the ink layer 7 and the lower surface of the anti-fall plate 6. Since there is another layer of anti-fall plate 6 on the top of the cover plate 1, and the adhesive layer 8 is printed on the back of the anti-fall plate 6, it covers the ink layer 7 in the non-visible area and the lower surface of the anti-fall plate 6 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 1 can be fully laminated with the upper polarizer of the TN screen 2 through the liquid optical adhesive 4. Since the cover plate 1 is not provided with an ink layer 7, it will not cause the phenomenon of laminating 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 the production and manufacturing costs of the liquid crystal display module will also be greatly reduced. Furthermore, since there is an anti-fall plate 6 on the STN screen 3, the pressure transmitted to the STN screen 3 can be basically ignored, thereby avoiding the situation where the STN screen 3 displays abnormally when being pressed by a finger.

[0034] And when the anti-fall plate 6 is impacted by external force, the anti-fall plate 6 will break first. Due to the buffering effect of the adhesive layer 8, the cover plate 1 is not easy to break, so the cover plate 1 and the main screen can be well protected. When the anti-fall plate 6 is broken, the anti-fall plate 6 can be easily peeled off, and only a new anti-fall plate 6 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, thereby meeting the company's growing quality requirements.

[0035] Further, the thickness of the ink layer 7 is 8 μm to 15 μm.

[0036] Furthermore, the thickness of the adhesive layer 8 is 50 μm.

[0037] Furthermore, the thickness of the anti-fall plate 6 is 5 mm to 10 mm, and the thickness of the cover plate 1 is 3 mm to 5 mm.

[0038] Furthermore, the upper surface of the anti-fall plate 6 is covered with an anti-fingerprint film layer to prevent user fingerprints from remaining on the anti-fall plate 6 and enhance the aesthetics.

[0039] 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.

[0040] Furthermore, the hardness of the anti-fall plate 6 is greater than the hardness of the cover plate 1 to enhance the protection effect.

[0041] 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.
