Description

Technical Field

[0001] The utility model relates to the technical field of LCD, and more specifically to an LCD structure with a protective film group. Background Art

[0002] LCD, the full name of which is "Liquid Crystal Display", means liquid crystal display. It is a flat panel display device that cannot emit light actively, but relies on the help of external light to display characters and images. LCD display uses two polarized materials with liquid crystal solution sandwiched between them. When current passes through, the liquid crystal arrangement becomes orderly, allowing light to pass through easily; when power is not turned on, the liquid crystal arrangement becomes chaotic, preventing light from passing through. In this way, LCD displays graphics; LCD has the characteristics of low power consumption, small size, light weight, ultra-thin, ultra-fine, soft picture, and no damage to eyesight; LCD has a wide range of applications, including televisions, computer monitors, mobile phones, tablets, digital cameras, electronic watches, calculators, game consoles, navigators, instruments and meters, etc.

[0003] There is a protective film on the surface of the upper polarizer of the LCD, and a piece of adhesive paper is usually attached to the protective film. When the product is used in the terminal, it needs to tear off the protective film on the surface of the polarizer on the adhesive paper and install the protective casing. Since the adhesive paper attached to the upper part of the LCD and the protective film on the surface of the upper polarizer are colorless and transparent, after the casing is installed, the protective casing will cover the colored tear handle of the adhesive paper, which is not easy to find visually, resulting in the LCD being installed as a whole without removing the protective film, affecting the overall display effect of the LCD. Therefore, we have made improvements to this and proposed an LCD structure with a protective film group.

[0004] For example, a Chinese patent (publication number: CN220745764U) discloses a mucosal paper assembly, including a connecting film fixed to the torn object and a mucosal paper hand-pull tearing handle arranged at the end of the connecting film, and the front end of the connecting film is arranged on the inner side of the torn object; on the torn object, the connecting film extends from the inner side of the torn object to the outer side of the torn object, and after reaching the edge of the torn object, it is folded to the inner side of the torn object. And its specification discloses: screen mucosal paper is generally made of polymer materials, such as polyester or polyvinyl methacrylate. These materials have the characteristics of high transparency, good flexibility, wear resistance, etc., and can effectively protect the screen. The above patents can prove the defects of the prior art. Utility Model Content

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.

[0026] As described in the background technology, there is a protective film on the surface of the upper polarizer of the LCD, and a piece of sticky paper is usually attached to the protective film. When the product is used in the terminal, it is necessary to tear off the protective film on the surface of the polarizer on the sticky paper and install it on the protective casing. Since the sticky paper attached to the upper part of the LCD and the protective film on the surface of the upper polarizer are colorless and transparent, after the casing is installed, the protective casing will cover the colored tear handle of the sticky paper, which is not easy to find visually, resulting in the LCD being installed as a whole machine without removing the protective film, affecting the overall display effect of the LCD.

[0027] In order to solve this technical problem, the utility model provides an LCD structure with a protective film group.

[0028] Specifically, please refer to Figure 1-Figure 2 , the LCD structure with protective film group specifically includes:

[0029] LCD module 1, LCD module 1 includes an upper polarizer 101, a protective film structure 2 is arranged on the upper polarizer 101, the protective film structure 2 includes a protective piece attached to the upper polarizer 101 and a tearing piece arranged on the protective piece, the tearing piece is used to tear off the protective piece from the upper polarizer 101 under the traction of an external force, and an identification piece is arranged on the tearing piece, the identification piece is used to assist in confirming whether the protective piece is torn off.

[0030] The LCD structure with a protective film group provided by the utility model has an identification piece arranged on the tear-off piece. When the protective housing is installed, the protection housing will not cover the identification piece, so that the identification piece can assist in confirming whether the protective piece has been torn off, thereby reducing the situation where the protective piece is missed and affects the overall display effect of the LCD.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] Embodiment 1 of the LCD structure with a protective film group of the utility model

[0035] Please refer to Figure 1-Figure 2 The LCD structure with a protective film group of the utility model includes: an LCD module 1, the LCD module 1 includes an upper polarizer 101, a protective film structure 2 is arranged on the upper polarizer 101, the protective film structure 2 includes a protective member attached to the upper polarizer 101 and a tearing member arranged on the protective member, the tearing member is used to tear off the protective member from the upper polarizer 101 under the traction of an external force, and an identification member is arranged on the tearing member, and the identification member is used to assist in confirming whether the protective member is torn off.

[0036] Further, such as Figure 1 As shown, the protective member is a transparent protective film body 201, which is attached to the upper polarizer 101. The transparent protective film body 201 can provide a physical barrier to the upper polarizer 101. During the production, transportation and storage process, the upper polarizer 101 may be threatened by various external factors, such as scratches by sharp objects, adhesion of dust and erosion by chemical substances. The transparent protective film body 201 can effectively block these potential damage factors, thereby ensuring that the upper polarizer 101 is intact; secondly, the transparent protective film body 201 also has excellent anti-fouling performance, which can effectively prevent dust, grease and other pollutants from adhering to the surface of the upper polarizer 101, thereby keeping the polarizer clean and transparent. In summary, the transparent protective film body 201 plays an indispensable role in protecting the upper polarizer 101. It ensures that the upper polarizer 101 can maintain excellent performance and appearance quality throughout its life cycle by providing multiple protections such as physical barriers, scratch resistance, anti-fouling performance and electrostatic protection functions.

[0037] Further, such as Figure 1-Figure 2 As shown, the tearing piece includes an adhesive film paper body 202, which is pasted on the side of the transparent protective film body 201 away from the upper polarizer 101. The setting of the adhesive film paper body 202 can facilitate the tearing of the transparent protective film body 201, that is, when the adhesive film paper body 202 is pulled, the adhesive film paper body 202 can drive the transparent protective film body 201 to separate from the upper polarizer 101, thereby tearing off the transparent protective film body 201 before the upper polarizer 101 is assembled with the protective casing.

[0038] Further, such as Figure 2 As shown, the identification piece is identification ink 203, and the identification ink 203 is set on the side of the mucosal paper body 202 away from the transparent protective film body 201. The identification ink 203 is used to assist in confirming whether the transparent protective film body 201 is torn off from the upper polarizer 101. The identification ink 203 is set on the mucosal paper body 202 by silk screen printing. The identification ink 203 uses an ink with a more conspicuous color, such as red ink. The setting of the identification ink 203 can facilitate the use of existing visual inspection systems or manual inspection to determine whether the identification ink 203 is torn off. When the protective casing is installed, the protective casing will not cover the identification piece, so that if the identification ink 203 is detected after the protective casing is installed, it indicates that the transparent protective film body 201 has not been torn off.

[0039] Embodiment 2 of the LCD structure with a protective film group of the utility model

[0040] like Figure 2-Figure 3 As shown, the LCD structure with a protective film group of the utility model is further that the adhesive paper body 202 includes a PET film layer 2021, and a glue layer 2022 is provided on the side of the PET film layer 2021 close to the upper polarizer 101, and the glue layer 2022 is adhered to the transparent protective film body 201. PET is a thermoplastic plastic. PET has the characteristics of high transparency, strong weather resistance, and good mechanical properties, making it an ideal material choice. It can effectively protect the covered object and can be easily torn off without leaving residual glue, thereby keeping the surface of the object clean and intact.

[0041] Furthermore, the bonding strength between the glue layer 2022 and the transparent protective film body 201 is greater than the bonding strength between the transparent protective film body 201 and the upper polarizer 101, so that the transparent protective film body 201 and the upper polarizer 101 can be easily separated during the pulling process.

[0042] Further, such as Figure 3 As shown, the marking ink 203 is disposed on a side of the PET film layer 2021 away from the glue layer 2022 .

[0043] Further, such as Figure 2 As shown, one side of the PET film layer 2021 extends out of the transparent protective film body 201 to form a tear handle 204, which is used to assist in pulling the PET film layer 2021, so that the tear handle 204 can be pulled when the transparent protective film body 201 is torn off with the aid of the adhesive paper body 202.

[0044] Further, such as Figure 3As shown, a handle identification layer 2023 is provided on the PET film layer 2021, the position of the glue layer 2022 corresponds to the position of the handle identification layer 2023, and the handle identification layer 2023 is screen-printed with ink of a different color from the identification ink 203. The setting of the handle identification layer 2023 can facilitate the identification of the tear handle 204 for use when tearing it off.

[0045] Further, such as Figure 4 As shown, a reinforcing film 3 is also adhered to the side of the transparent protective film main body 201 close to the upper polarizer 101, and one side of the reinforcing film 3 is fixedly connected to the mucus paper main body 202, and the side of the reinforcing film 3 away from the transparent protective film main body 201 is not bonded to the upper polarizer 101. The provision of the reinforcing film 3 can, on the one hand, improve the connection strength between the mucus paper main body 202 and the transparent protective film main body 201, and can also ensure that there is a part of non-bonded area between the area of ​​the transparent protective film main body 201 close to the mucus paper main body 202 and the upper polarizer 101, so that when the mucus paper main body 202 and the tearing handle 204 are pulled to tear off the transparent protective film main body 201, the transparent protective film main body 201 can be easily separated from the upper polarizer 101.

[0046] Embodiment 3 of the LCD structure with a protective film group of the utility model

[0047] like Figure 1 As shown, the LCD structure with a protective film group of the utility model further includes an upper glass 102 connected to an upper polarizer 101, a side of the upper glass 102 away from the upper polarizer 101 is connected to a lower glass 103, a side of the lower glass 103 away from the upper glass 102 is connected to a lower polarizer 104, both ends of the lower glass 103 are connected to metal clips PIN 105, and UV glue 106 is arranged between the metal clip PIN 105 and the lower glass 103. The role of arranging the UV glue 106 between the metal clip PIN 105 and the lower glass 103 is significant. The UV glue 106 ensures the adhesion between the two with its strong adhesion. The UV glue 106 has a strong bond with the metal clip PIN 105, which effectively prevents loosening or falling off due to external factors. At the same time, the connection layer formed after curing has excellent stability, can withstand various environmental challenges, and maintain a long-term and stable connection state. In addition, the high transparency of the UV glue 106 ensures the visual clarity between the metal clip PIN 105 and the lower glass 103, and will not affect the use effect. More importantly, the rapid curing characteristics of the UV glue 106 simplify the production process and improve the production efficiency. Therefore, the application of the UV glue 106 between the metal clip PIN 105 and the lower glass 103 not only achieves effective fixation and bonding, but also improves the stability of the overall structure and the production efficiency.
