Description

Technical Field

[0001] The utility model relates to the technical field of UV curing, and more specifically to a UV light shielding structure. Background Art

[0002] In the manufacturing process of display panels, especially in the manufacturing of liquid crystal display (LCD) panels, array and CF (color filter) are two key components. After the array and CF are film-formed, they will enter the box-forming process to accurately bond the two together to form a complete cell. In the box-forming process, in order to ensure that the array and CF are firmly bonded, seal glue needs to be applied on the border of the cell and cured by UV (ultraviolet light) curing technology;

[0003] However, during the UV curing process, UV light not only cures the seal glue, but may also irradiate the liquid crystal material inside the panel. Liquid crystal, as a polymer material, is sensitive to UV light. After being irradiated by UV light, it will decompose and produce impurities. These impurities will seriously affect the subsequent display quality, such as color distortion, contrast reduction, uneven brightness, etc. Therefore, we have made improvements to this and proposed a UV light shielding structure.

[0004] For example, a Chinese patent (publication number CN104834118B) discloses a method and device for manufacturing a liquid crystal display device, and its specification discloses that the display of the liquid crystal display device is performed by applying an electric field to the liquid crystal molecules in the liquid crystal layer sandwiched between a pair of substrates to change the orientation direction of the liquid crystal molecules, and by the resulting change in the optical properties of the liquid crystal layer. The orientation direction of the liquid crystal molecules when no electric field is applied is specified by the orientation film (the surface of the polyimide film has been subjected to friction treatment). However, there are problems such as the generation of static electricity or foreign matter caused by friction, and uneven friction caused by the concave and convex surface of the substrate. Therefore, a light orientation method that does not require contact with the friction cloth is currently used. Regarding the light orientation method, there is a method of imparting an orientation function to the surface of the organic film formed on the surface of the substrate by irradiating the surface of the organic film with UV light that is almost linearly polarized. Since the light orientation film will produce impurity decomposition products after being irradiated with UV light, it has been removed by heat treatment, etc. The above patents can prove the defects of the prior art.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] As described in the background technology, during the UV curing process, UV light not only cures the seal glue, but may also irradiate the liquid crystal material inside the panel. Liquid crystal, as a polymer material, is sensitive to UV light. After being irradiated by UV light, it will decompose and produce impurities. These impurities will seriously affect the subsequent display quality, such as color distortion, contrast reduction, uneven brightness, etc.

[0029] In order to solve this technical problem, the utility model provides a UV light shielding structure.

[0031] The display module 1 has a display panel body 102 . The display module 1 is provided with a shielding mechanism 2 . The shielding mechanism 2 is used to shield the display panel body 102 to prevent UV light from irradiating the display panel body 102 during the UV curing process.

[0032] The UV light shielding structure provided by the utility model is provided with a shielding mechanism 2 on the display module 1, and the shielding mechanism 2 can be used to shield the display panel main body 102, thereby blocking the UV light from irradiating the display panel main body 102 during the UV curing process, thereby reducing the influence of the UV light on the liquid crystal of the display panel main body 102, and reducing the situation in which the liquid crystal of the display panel main body 102 decomposes and produces impurities after being irradiated by UV light.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] Embodiment 1 of the UV light shielding structure of the utility model

[0037] Please refer to Figure 1-Figure 4 The UV light shielding structure of the utility model includes: a display module 1, the display module 1 has a display panel body 102, and a shielding mechanism 2 is arranged on the display module 1, and the shielding mechanism 2 is used to shield the display panel body 102 to block the UV light from irradiating the display panel body 102 during the UV curing process, thereby reducing the influence of the UV light on the liquid crystal of the display panel body 102, and reducing the situation where the liquid crystal of the display panel body 102 is decomposed and produces impurities after being irradiated by UV light.

[0038] Further, such as Figure 2 As shown, the display module 1 also includes an array substrate body 101, and a display panel body 102 is arranged on the array substrate body 101. The array substrate is also called a lower substrate, which is a key layer in the LCD panel structure. It mainly includes a lower orientation film (used to control the initial orientation of liquid crystal molecules), the array substrate itself, and a lower polarizer. The main function of the array substrate is to provide pixel driving and control signals to ensure that the liquid crystal panel can display images correctly and stably. It controls the voltage of the pixel electrode through the TFT thin film transistor, thereby controlling the arrangement and rotation of the liquid crystal molecules to realize the display of the image. The quality of the array substrate directly affects the performance and quality of the liquid crystal display panel.

[0039] Further, such as Figure 1 and Figure 3 As shown, the shielding mechanism 2 is arranged on a side of the display module 1 close to the display panel body 102 to shield the display panel body 102, reduce the influence of UV light on the liquid crystal of the display panel body 102, and reduce the decomposition and generation of impurities of the liquid crystal of the display panel body 102 after being irradiated by UV light.

[0040] Further, such as Figure 2As shown, a seal glue body 103 is arranged between one side of the array substrate body 101 close to the shielding mechanism 2 and the display panel body 102. The seal glue body 103 is used to connect the array substrate body 101 and the display panel body 102 together. The seal glue body 103 is cured under UV light. The seal glue is a special adhesive used in liquid crystal panels. Its main purpose is to bond the array substrate body 101 and the display panel body 102 together to ensure that the liquid crystal molecules are confined inside the panel and prevent the liquid crystal from flowing out. At the same time, it also provides a barrier between the liquid crystal molecules in the panel and the outside world, protecting the liquid crystal from external moisture and impurities; Seal frame glue can be divided into two categories: thermal curing type and UV curing type. Thermal curing type is a traditional process, while UV curing type is more common in new production lines. The main components of Seal frame glue include epoxy resin or acrylate (Acrylate) as the main body, with hardener, filler, additives and solvents. Among them, the hardener reacts with the main component to harden the frame glue, and the filler strengthens the mechanical and heat resistance of the frame glue, reducing shrinkage and thermal expansion.

[0041] Furthermore, the shielding mechanism 2 includes a glass substrate 201, which is transparent and can be detachably arranged on the array substrate body 101. The reason why the glass substrate 201 is made of glass is that it can prevent the glass substrate 201 from directly shielding the display module 1, that is, the glass substrate 201 does not affect the UV light irradiation of the Seal frame glue body 103 area during the curing process.

[0042] Further, such as Figure 3 As shown, a UV shielding layer 202 is provided on the glass substrate 201, and the position of the UV shielding layer 202 corresponds to the position of the display panel main body 102, and the UV shielding layer 202 is used to shield the display panel main body 102. The shielding mechanism 2 is arranged by sputtering a whole layer of metal aluminum film on the glass substrate 201, and then using laser technology to melt away the unnecessary metal aluminum layer pattern on the glass surface, leaving the required aluminum layer pattern, and the remaining aluminum layer pattern is the UV shielding layer 202. In this way, the UV shielding layer 202 can be easily produced, which saves time compared with the traditional use of UV Mask, and also reduces the production and transportation cycle, thereby improving work efficiency.

[0043] Embodiment 2 of the UV light shielding structure of the utility model

[0044] The UV light shielding structure of the utility model is further as follows: Figure 5As shown, positioning members are provided on the glass substrate 201 and the array substrate body 101, and the positioning members are used to position the glass substrate 201 and the array substrate body 101, thereby facilitating the alignment of the UV shielding layer 202 and the display panel body 102, thereby reducing position deviation or causing UV light to irradiate the display panel body 102.

[0045] Further, such as Figure 5 As shown, the positioning member includes a plurality of positioning holes 3, and the plurality of positioning holes 3 are respectively opened on the glass substrate 201 and the array substrate body 101, and the positioning holes 3 on the glass substrate 201 correspond to the positioning holes 3 on the array substrate body 101, that is, when the glass substrate 201 and the array substrate body 101 are attached, a rod member with a diameter matching the positioning hole 3 can be used to insert into the positioning hole 3 on the glass substrate 201 and the array substrate body 101 to realize the positioning of the glass substrate 201 and the array substrate body 101.

[0046] Embodiment 3 of the UV light shielding structure of the utility model

[0047] The UV light shielding structure of the utility model is further as follows: Figure 6 As shown, the glass substrate 201 and the array substrate body 101 are both provided with positioning members, which are used to position the glass substrate 201 and the array substrate body 101, thereby facilitating the alignment of the UV shielding layer 202 and the display panel body 102, thereby reducing the position deviation or causing the UV light to irradiate the display panel body 102.

[0048] like Figure 6 As shown, positioning adhesive tapes 4 are pasted on both sides of the glass substrate 201. The positioning adhesive tapes 4 are used to fix the glass substrate 201 and the array substrate body 101 after they are bonded together. After the glass substrate 201 and the array substrate body 101 are bonded together, the positioning adhesive tapes 4 are pasted to the side and bottom diameter of the glass substrate 201, thereby reducing the offset between the glass substrate 201 and the array substrate body 101 during use.

[0049] Further, such as Figure 6 As shown, a non-glue handle 401 is fixedly connected to the side of the positioning adhesive tape 4 away from the glass substrate 201. The non-glue handle 401 is used to separate the positioning adhesive tape 4 from the array substrate body 101 after bonding. When the UV curing is completed, when the glass substrate 201 needs to be separated from the array substrate body 101, the non-glue handle 401 is pulled to separate the positioning adhesive tape 4 from the array substrate body 101. The positioning adhesive tape 4 can be repeatedly pasted. When the viscosity of the positioning adhesive tape 4 decreases, it can be torn off from the glass substrate 201 and a new positioning adhesive tape 4 can be pasted.

[0050] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive.
