Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screens, and more specifically, to a liquid crystal display screen structure. Background Art

[0002] In modern mobile phone display technology, TFT (thin film transistor) display module is one of the core components. Its performance and display effect are directly related to the user's visual experience and the overall performance of the device. In order to improve the stability and anti-static ability of the TFT module, the industry generally covers a shielding ITO (indium tin oxide) layer on the upper surface of the TFT glass. This layer can not only effectively prevent static electricity from damaging the display module, but also improve its overall performance. In order to further enhance the anti-static effect of the TFT module, the existing technology often uses a high-impedance layer polarizer, also known as an AS polarizer. This polarizer has a special structure. It can effectively disperse and reduce the impact of static electricity on the display module through its high impedance characteristics. However, relying solely on polarizers is not enough to completely solve the static electricity problem. Therefore, the industry has also introduced conductive silver paste.

[0003] Conductive silver paste is coated on the PSA (pressure sensitive adhesive) layer on the polarizer, and connected to the ground point of the lower glass through this layer, thus forming a conductive channel to effectively conduct static electricity away. However, although this method improves the antistatic ability of the TFT module, it also brings new problems; the solvent components contained in the conductive silver paste will react with the PSA glue, causing the two to blend and produce corrosion bubbles. These bubbles may not only damage the internal structure of the display module, but more importantly, if the position of the silver paste coating is too close to the visible area of ​​the glass, the corrosion bubbles will become visible to the naked eye, seriously affecting the appearance quality of the product. Therefore, we have made improvements to this and proposed a liquid crystal display structure.

[0004] For example, a Chinese patent (publication number CN216901222U) discloses a display module that does not require conductive silver paste. Its specification discloses: static electricity is usually generated in liquid crystal display modules, so liquid crystal display modules need to conduct static electricity. The traditional structure is to release static electricity by connecting the ground electrode and the upper polarizer PSA layer in the display module. Since the solvent of the conductive silver paste will corrode the PSA layer and PVA layer of the upper polarizer, corrosion bubbles will be generated. Therefore, after the high temperature and high humidity test, the corrosion situation will be more serious. Once the VA area is corroded, the appearance of the product will be affected, which will increase the probability of defective products, greatly increase the production and manufacturing costs of the products, reduce the competitiveness of the products, and fail to meet the growing quality requirements of enterprises. The above patents can prove the defects of the existing technology. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the present utility model is that the solvent components contained in the conductive silver paste will blend with the PSA glue on the polarizer, resulting in corrosion bubbles at a certain distance. If the conductive silver paste is too close to the visible area of ​​the glass, corrosion bubbles will be seen, resulting in a poor appearance.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A liquid crystal display structure comprises: a liquid crystal display body, wherein the liquid crystal display body comprises an upper polarizer body and a lower glass body stacked in sequence, wherein the upper polarizer body has an R angle, and an electrostatic transfer portion is arranged between the outer side of the R angle of the upper polarizer body and the lower glass body. The present application significantly reduces the risk of corrosion bubbles entering the visible area by changing the coating position of the conductive silver paste body. Specifically, the conductive silver paste body is arranged in the R angle direction of the upper polarizer body to increase the distance between the conductive silver paste body and the visible area, thereby greatly reducing the risk of corrosion bubbles entering the visible area and improving the yield of the product.

[0008] As an improved manner of the utility model, the static electricity transfer part is used to conduct static electricity outward to achieve static electricity release.

[0009] As an improved manner of the utility model, the electrostatic transfer portion includes a grounding point, and the grounding point is arranged on the lower glass body.

[0010] As an improved method of the utility model, the electrostatic transfer part also includes a conductive silver paste body, which is arranged between the lower glass body on the outer side of the R angle of the upper polarizer body, and the conductive silver paste body is connected to the grounding point.

[0011] As an improved manner of the utility model, an upper glass body is connected between the upper polarizer body and the lower glass body, and the upper glass body is connected to a conductive silver paste body.

[0012] As an improved method of the utility model, the liquid crystal display screen body has a viewing area, and the distance between the outer side of the R angle of the upper polarizer body and the viewing area is greater than the distance between the bottom edge of the upper glass body and the viewing area.

[0013] As an improved manner of the utility model, the liquid crystal display screen body further comprises a lower polarizer body, and the lower polarizer body is connected to a side of the upper glass body away from the lower glass body.

[0014] As an improved manner of the utility model, a welding pad is arranged on the lower glass body, and the lower glass body is connected to the FPC body via the welding pad.

[0015] As an improved approach of the utility model, a driving IC is also arranged on the lower glass body.

[0016] As an improved manner of the utility model, the outer surfaces of the lower glass body and the upper glass body are both provided with coatings, and the positions of the coatings correspond to the positions of the conductive silver paste body.

[0017] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0018] In order to solve the problem in the prior art that the solvent components contained in the conductive silver paste will blend with the PSA glue on the polarizer, resulting in corrosion bubbles at a certain distance.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Reference to "embodiments" herein means that specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] As described in the background technology, the conductive silver paste is coated on the PSA (pressure sensitive adhesive) layer on the polarizer, and connected to the grounding point of the lower glass through this layer, thereby forming a conductive channel to effectively conduct static electricity away. However, although this method improves the anti-static ability of the TFT module, it also brings new problems; the solvent components contained in the conductive silver paste will react with the PSA glue, causing the two to blend and produce corrosion bubbles. These bubbles may not only damage the internal structure of the display module, but more importantly, if the position where the silver paste is coated is too close to the visible area of ​​the glass, the corrosion bubbles will become visible to the naked eye, seriously affecting the appearance quality of the product.

[0026] In order to solve this technical problem, the utility model provides a liquid crystal display screen structure.

[0027] Specifically, please refer to Figure 1-Figure 3 , the LCD display structure specifically includes:

[0028] The liquid crystal display screen body 1 includes an upper polarizer body 103 and a lower glass body 101 stacked together in sequence. The upper polarizer body 103 has an R angle, and an electrostatic transfer part is arranged between the outer side of the R angle of the upper polarizer body 103 and the lower glass body 101.

[0029] The liquid crystal display structure provided by the utility model significantly reduces the risk of corrosion bubbles entering the visible area by changing the coating position of the conductive silver paste body 3. Specifically, the conductive silver paste body 3 is set in the angular direction of the upper polarizer body 103R to increase the distance between the conductive silver paste body 3 and the visible area, thereby greatly reducing the risk of corrosion bubbles entering the visible area and improving the yield of the product.

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0033] Embodiment 1 of the structure of the liquid crystal display screen of the utility model

[0034] Please refer to Figure 1-Figure 3 The structure of the liquid crystal display screen of the utility model includes: a liquid crystal display screen body 1, the liquid crystal display screen body 1 includes an upper polarizer body 103 and a lower glass body 101 stacked together in sequence, the upper polarizer body 103 has an R angle, and an electrostatic transfer part is arranged between the outer side of the R angle of the upper polarizer body 103 and the lower glass body 101. The present application significantly reduces the risk of corrosion bubbles entering the visible area by changing the coating position of the conductive silver paste body 3. Specifically, the conductive silver paste body 3 is arranged in the R angle direction of the upper polarizer body 103 to increase the distance between the conductive silver paste body 3 and the visible area, which greatly reduces the risk of corrosion bubbles entering the visible area and improves the yield of the product.

[0035] Furthermore, the static electricity transfer part is used to conduct static electricity outwards to achieve the release of static electricity and reduce the damage caused by static electricity to the liquid crystal display screen body 1.

[0036] Further, such as Figure 1 and Figure 2 As shown, the electrostatic transmission part includes a grounding point 2 , and the grounding point 2 is arranged on the lower glass body 101 .

[0037] Further, such as Figure 1 and Figure 2 As shown, the electrostatic transfer part also includes a conductive silver paste body 3, which is arranged between the lower glass body 101 on the outer side of the upper polarizer body 103R corner, and the conductive silver paste body 3 is connected to the grounding point 2.

[0038] Further, such as Figure 1-Figure 3 As shown, an upper glass body 102 is connected between the upper polarizer body 103 and the lower glass body 101, and the upper glass body 102 is connected to the conductive silver paste body 3, and the upper polarizer body 103 is a high impedance layer polarizer;

[0039] High impedance layer polarizer is a special type of polarizer with high impedance characteristics. High impedance layer polarizer is also commonly called AS polarizer. It is an optical film with a tiny grating structure that can block polarized light with a polarization direction perpendicular to the grating structure, and only allow polarized light parallel to the grating structure to pass through. The polarizer contains a linear polarization structure with a certain swing angle, usually at a 45-degree angle. This structure allows only light parallel to the polarization direction to pass through, while light perpendicular to the polarization direction is blocked; when natural light passes through the polarizer, the light perpendicular to the transmission axis of the polarizer will be absorbed, and only the light parallel to the transmission axis can pass through, thereby forming a light-dark contrast and realizing the function of picture display;

[0040] One of the main features of high-impedance layer polarizer is its high impedance property, which enables it to effectively suppress reflection and reduce the intensity of reflected light to a very low level. By suppressing reflection, high-impedance polarizer can improve the clarity and visibility of the image, so that the image will not be disturbed by reflected light when viewing. High-impedance layer polarizer is widely used in electronic products and optical devices, especially in occasions where it is necessary to improve the display effect and clarity.

[0041] Embodiment 2 of the structure of the liquid crystal display screen of the utility model

[0042] The utility model further has a liquid crystal display screen structure, such as Figure 2 As shown, the liquid crystal display screen body 1 has a viewing area, and the distance between the outer side of the upper polarizer body 103R angle and the viewing area is greater than the distance between the bottom edge of the upper glass body 102 and the viewing area. For ease of understanding, this application uses AA to represent the viewing area and marks it in the figure.

[0043] Further, such as Figure 3 As shown, the liquid crystal display screen body 1 further includes a lower polarizer body 106, and the lower polarizer body 106 is connected to a side of the upper glass body 102 away from the lower glass body 101;

[0044] The upper polarizer body 103 is mainly used to analyze the polarized light after being electrically modulated by the liquid crystal. The liquid crystal layer will modulate the polarization state of the incident light according to the electrical signal. The upper polarizer body 103 is responsible for analyzing these modulated polarized lights, and by controlling the direction and intensity of the transmitted light, it produces a contrast between light and dark, thereby forming the display screen we see. The lower polarizer body 106 cooperates with the upper polarizer body 103. The upper polarizer body 103 is an indispensable part of forming the display image. It ensures that only polarized light in a specific direction can pass through, thereby producing a clear image.

[0045] The main function of the lower polarizer body 106 is to convert the non-polarized light emitted by the backlight assembly into polarized light in a specific direction. The light emitted by the backlight assembly is originally non-polarized light vibrating in all directions. After passing through the lower polarizer body 106, only the light parallel to the transmission axis of the lower polarizer body 106 can pass through and become polarized light.

[0046] The lower glass body 101 and the upper glass body 102 serve as the basic structure of the liquid crystal display screen body 1 and provide stable support for various components. At the same time, they also play a role in protecting internal components from external physical damage.

[0047] Embodiment 3 of the structure of the liquid crystal display screen of the utility model

[0048] The utility model further has a liquid crystal display screen structure, such as Figure 1 As shown, a solder pad is provided on the lower glass body 101, and the lower glass body 101 is connected to the FPC body 104 through the solder pad. The static electricity on the upper glass body 102 and the upper polarizer body 103 is transferred to the FPC body 104 through the grounding point 2 and the conductive silver paste body 3 and finally released to the outside through the FPC body 104.

[0049] Further, such as Figure 1 As shown, a driver IC 105 is also provided on the lower glass body 101. The driver IC 105 receives input signals from a host or other devices, such as video signals or data signals, and then processes and converts these signals to ensure that they meet the input requirements of the display, so that the LCD display body 1 can correctly interpret and display these signals.

[0050] Further, such as Figure 1 As shown, the outer surfaces of the lower glass body 101 and the upper glass body 102 are both provided with a coating, and the position of the coating corresponds to the position of the conductive silver paste body 3. The coating can increase the surface energy and hydrophilicity of the lower glass body 101 and the upper glass body 102, thereby optimizing the adhesion between the conductive silver paste body 3 and the lower glass body 101 and the upper glass body 102, and effectively reducing the generation of corrosion bubbles. The coating material is selected from, including but not limited to, organic silicon compounds, fluorocarbon compounds or other compounds with high molecular polarity and hydrophilic groups. These materials can effectively improve the surface properties of the glass substrate.
