[0027] The present utility model provides a liquid crystal display screen for preventing the antistatic function of an IC from failing. It includes a rubber frame, and a lower polarizer, a lower substrate, an upper substrate, and an upper polarizer are sequentially stacked from bottom to top on the rubber frame. The lower substrate extends outwards with a step and is longer than the upper substrate. A driving IC is bonded to the upper surface of the lower substrate at the step. An upper iron frame and a lower iron frame that are buckled with each other are respectively arranged above and below the rubber frame. The upper iron frame is located above the driving IC, and a soft foam is pasted on the lower surface of the upper iron frame, and the soft foam abuts against and compresses the driving IC.

[0028] Cancel the black insulating protective paper in the traditional structure, change the black insulating protective paper to a soft foam, and make the soft foam compressed between the upper iron frame and the driving IC. At the same time, paste the soft foam on the lower surface of the upper iron frame. In this way, even if the adhesiveness weakens after a long use time, the soft foam can still be fixed above the driving IC by the friction force of compression, preventing the driving IC from separating from the soft foam, thereby preventing the antistatic function of the driving IC from failing.

[0029] In order to enable those skilled in the art to better understand the solution of 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 utility model will be described in detail below in conjunction with the drawings and embodiments. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0030] Please refer to Figure 1 , which is a liquid crystal display screen for preventing the antistatic function of an IC from failing provided by the present utility model. It includes a rubber frame 1. A lower polarizer, a lower substrate 2, an upper substrate 3, and an upper polarizer are sequentially stacked from bottom to top on the rubber frame 1. The lower substrate 2 extends outwards with a step and is longer than the upper substrate 3. A driving IC 4 is bonded to the upper surface of the lower substrate 2 at the step. An upper iron frame 5 and a lower iron frame 6 that are buckled with each other are respectively arranged above and below the rubber frame 1. The upper iron frame 5 is located above the driving IC 4, and a soft foam 7 is pasted on the lower surface of the upper iron frame 5, and the soft foam 7 abuts against and compresses the driving IC 4. Cancel the black insulating protective paper in the traditional structure, change the black insulating protective paper to a soft foam 7, and make the soft foam 7 compressed between the upper iron frame 5 and the driving IC 4. At the same time, paste the soft foam 7 on the lower surface of the upper iron frame 5. In this way, even if the adhesiveness weakens after a long use time, the soft foam 7 can still be fixed above the driving IC 4 by the friction force of compression, preventing the driving IC 4 from separating from the soft foam 7, thereby preventing the antistatic function of the driving IC 4 from failing.

[0031] Furthermore, the soft foam 7 is a single-sided adhesive foam. The soft foam 7 is fixedly adhered to the lower surface of the upper iron frame 5, which not only fixes the soft foam 7 but also prevents the soft foam 7 from sticking to the driving IC 4 and causing the driving IC 4 to shift, thus avoiding the failure of the driving IC 4 function.

[0032] Furthermore, the soft foam 7 is a double-sided adhesive foam. The upper surface of the soft foam 7 is fixedly adhered to the lower surface of the upper iron frame 5, and the lower surface of the soft foam 7 is fixedly adhered to the driving IC 4 to further firmly fix the soft foam 7 and the driving IC 4 together.

[0033] Please refer to Figure 2 and Figure 3 , as a further optimized solution of Embodiment 1, in this embodiment, a strong adhesive glue 71 is provided on the upper surface of the soft foam 7, and a weak adhesive glue 72 is provided on the lower surface of the soft foam 7. The strong adhesive glue 71 can firmly adhere the soft foam 7 to the upper iron frame 5 to prevent it from falling off. The weak adhesive glue 72 has a weaker adhesive force. While ensuring the firm adhesion between the soft foam 7 and the driving IC 4, it can also prevent the driving IC 4 from being pulled due to excessive adhesive force when deforming at high temperature or vibrating greatly, thus avoiding the failure of the driving IC 4 function.

[0034] Furthermore, the ratio of the initial adhesive force of the strong adhesive glue 71 to the weak adhesive glue 72 is 2:1 to 50:1, and the ratio of the initial adhesive force of the strong adhesive glue 71 to the weak adhesive glue 72 is controlled to achieve the purpose of controlling the adhesive force of the strong adhesive glue 71 and the weak adhesive glue 72.

[0035] More preferably, as another implementation manner of the present utility model, in this embodiment, the weak adhesive glue 72 and the strong adhesive glue 71 use the same adhesive, that is, the same kind of glue, but different viscosities are achieved by controlling the coating method of the glue. Among them, the glue of the weak adhesive glue 72 is coated in a grid pattern, while the glue of the strong adhesive glue 71 is completely coated. Since the adhesives of the weak adhesive glue 72 and the strong adhesive glue 71 are the same, only one type of glue needs to be purchased, which increases the quantity of glue purchased, reduces the procurement cost, and also makes it not easy to mix up during the glue coating process, improves production efficiency, and avoids misusing adhesives with different viscosities. The coating shape of the weak adhesive glue 72 is grid-shaped, which is equivalent to reducing the glue area of the weak adhesive glue 72, thereby reducing the adhesive force of the weak adhesive glue 72.

[0036] Furthermore, the soft foam 7 includes an upper foam 73 and a lower foam 74 disposed below the upper foam 73. The upper foam 73 and the lower foam 74 have different colors. In this embodiment, the color of the upper foam 73 is red and the color of the lower foam 74 is green. When pasting, the two sides of the weak adhesive 72 and the strong adhesive 71 can be identified by recognizing the different colors of the upper and lower layers, which plays a role in preventing mistakes. Furthermore, it can avoid reversing the strong adhesive 71 and the weak adhesive 72 during assembly, thereby improving the assembly efficiency and reducing the generation of defective products.

[0037] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "coupling", "fixing", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection, an electrical connection, or communication with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0038] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The drawings show the preferred embodiments of the present application, but 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 disclosed content of the present application more thorough and comprehensive.
