Description

Technical Field

[0001] The utility model relates to the field of display modules, and in particular to a connection structure between a small-size cover plate and a display module. Background Art

[0002] Liquid crystal display devices have been widely used in various information, communication and consumer electronic products due to their advantages of light weight, small size and low power consumption. The liquid crystal display module is the core display device in the liquid crystal display device, and the liquid crystal display module is mainly composed of a backlight and a liquid crystal display screen. At present, a cover plate needs to be attached to the surface of the liquid crystal display screen, and the cover plate needs to be aligned with the liquid crystal display screen to ensure that the cover plate and the liquid crystal display screen are completely fitted.

[0003] For example, in the prior art, such as the patent document with application number CN202321521723.7, a display module is disclosed for preventing the cover plate from being offset. The cover plate is conveniently aligned with the display screen by setting alignment retaining walls and corner retaining walls when the cover plate is fitted with the display screen, so that the cover plate is fitted downward along the inner walls of the alignment retaining walls and the corner retaining walls to avoid the cover plate from being offset.

[0004] Although the technical solution provided in the above patent document can avoid the offset of the cover plate alignment to a certain extent, there are still limitations in actual operation, because for small-sized cover plates, full lamination and alignment with LCD liquid crystal display panels is a process with relatively high technical requirements, which generally requires CCD alignment and grabbing to operate so that the edge of the small-sized cover plate can be aligned with the corresponding display module. Especially for products with non-pure circular viewing areas, it is inconvenient to grab and it is easy for part of the edge to be slightly offset when aligning the edge, and it is necessary to fine-tune the position alignment multiple times. However, in this way, each lamination can only be performed for a single product, resulting in low overall lamination production efficiency. Utility Model Content

[0034] 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.

[0035] In the description of the present utility model, the English abbreviations and phrases used have definite Chinese meanings. The English abbreviations and phrases without annotations or explanations are technical terms well known to those skilled in the art. The English abbreviations and phrases with other meanings are annotated in Chinese as follows:

[0036] LCD is the abbreviation of Liquid Crystal Display, which is translated into Chinese as: liquid crystal display.

[0037] FOG stands for "Film-on-Glass", which means a thin film on a glass substrate. FOG technology is a technology widely used in the manufacture of liquid crystal displays to reduce reflections and improve the quality of displayed images. FOG technology reduces interference and reflection of external light by coating a thin film on the glass substrate, thereby improving the contrast and brightness of the display. This film is usually composed of multiple layers, such as a transparent conductive layer, an alignment layer, and a polarizing layer, to enable the normal operation of the liquid crystal display. The use of FOG technology can improve the visual effect of the liquid crystal display, reduce glare and reflection, and improve the clarity and visibility of the displayed image.

[0038] OCA stands for "Optically Clear Adhesive". OCA is a transparent adhesive commonly used in the assembly and packaging process of liquid crystal displays. OCA is mainly used to bond liquid crystal panels and touch screens or other transparent covers together to form an integrated liquid crystal display device. It has high transparency, excellent optical properties and bonding performance, can provide clear and stable display effects, and ensure accurate transmission of displayed images. The use of OCA can prevent air or dust from entering between the liquid crystal display and the cover, reduce light scattering and reflection, and improve the clarity and brightness of the displayed image. In addition, OCA also has anti-UV, anti-yellowing and high temperature resistance properties, which can ensure the long-term stability and reliability of liquid crystal displays.

[0039] Chemical tempering: Chemical ion exchange on the surface of glass increases the surface tension of the glass and improves the impact resistance of the glass.

[0040] High temperature peelable adhesive: A type of tape that has strong adhesiveness at room temperature, but becomes less adhesive after being exposed to high temperatures, and can be easily peeled off without leaving any adhesive residue.

[0041] ICON: Pattern or symbol silk-screened on the glass cover, such as button icons.

[0042] TLI stands for "Thin Film Transistor Liquid Crystal Display". TLI is a liquid crystal display technology widely used in products such as flat-panel TVs, computer monitors and mobile devices. TLI technology uses thin film transistors (TFT) as the driving element of the liquid crystal display. Each pixel has an independent transistor to control its brightness and color. This structure enables TLI displays to achieve higher resolution, faster response time and wider viewing angles. Compared with traditional liquid crystal display technology, TLI displays are thinner, lighter and more energy-efficient.

[0043] TFT stands for "Thin Film Transistor". TFT technology is a key technology used to drive liquid crystal displays. TFT technology controls the brightness and color of liquid crystal pixels by making a thin film transistor array on a glass substrate. Each pixel has an independent thin film transistor to drive the arrangement of liquid crystal molecules to achieve pixel switching control. This structure enables the LCD display to accurately control the brightness and color of each pixel, thereby achieving high resolution, high contrast and fast response display effects.

[0044] As described in the background art, there is a problem of increasing pressure on auxiliary material costs.

[0045] In order to solve this technical problem, the utility model provides a small-size cover plate and display module connection structure.

[0046] Specifically, please refer to Figure 1-Figure 8 , a small-size cover plate and a display module connection structure, comprising:

[0047] A fixture 1, with a plurality of cover plates 3 detachably connected to its surface;

[0049] The multiple cover plates 3 are respectively arranged corresponding to the multiple display modules 4, and the clamp 1 can be fitted with the clamp 2 2;

[0050] When the clamp 1 and the clamp 2 are attached to each other, each cover plate 3 and each display module 4 are attached to each other to form a liquid crystal display assembly (liquid crystal display assembly, namely TLI).

[0051] The utility model can realize the assembly of multiple cover plates 3 and multiple display modules 4 at the same time through the cooperation of clamp 1 and clamp 2 2, will not be limited by the size of the cover plates 3, and can realize the assembly and formation of liquid crystal display components with high efficiency. Specifically, the multiple cover plates 3 and the multiple display modules 4 are respectively arranged on clamp 1 and clamp 2 2, and then the clamp 1 and the clamp 2 2 are fitted together. At this time, each cover plate 3 is correspondingly fitted with each display module 4 to form a liquid crystal display component.

[0052] 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 accompanying drawings.

[0053] 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.

[0054] 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.

[0055] Example 1

[0056] Please refer to Figure 1-3 , a small-size cover plate and a display module connection structure, comprising:

[0057] A fixture 1, with a plurality of cover plates 3 detachably connected to its surface;

[0058] A second fixture 2, with a plurality of display modules 4 connected to its surface;

[0059] The multiple cover plates 3 are respectively arranged corresponding to the multiple display modules 4, and the clamp 1 can be fitted with the clamp 2 2;

[0060] When the clamp 1 and the clamp 2 are attached to each other, each cover plate 3 and each display module 4 are attached to each other to form a liquid crystal display assembly.

[0061] The utility model can realize the assembly of multiple cover plates 3 and multiple display modules 4 at the same time through the cooperation of clamp 1 and clamp 2 2, will not be limited by the size of the cover plates 3, and can realize the assembly and formation of liquid crystal display components with high efficiency. Specifically, the multiple cover plates 3 and the multiple display modules 4 are respectively arranged on clamp 1 and clamp 2 2, and then the clamp 1 and the clamp 2 2 are fitted together. At this time, each cover plate 3 is correspondingly fitted with each display module 4 to form a liquid crystal display component.

[0062] In some specific embodiments, the cover plate 3 is fixedly connected with the clamp 1;

[0063] The clamp 1 includes an upper piece 10 and a lower piece 11 fixed to the upper piece 10. A plurality of through holes 12 are arranged on the surface of the upper piece 10 (the size of the through holes is close to the size of the cover plate 3, and the holes are used to place the cover plate 3). Each through hole 12 is arranged corresponding to each cover plate 3, and the cover plate 3 is inserted into the through hole and bonded to the surface of the lower piece 11.

[0064] In order to realize the operation of clamping and fixing the cover plate 3 and the clamp 1, the upper piece 10 and the lower piece 11 (the upper piece 10 and the lower piece 11 refer to two pieces of glass) are first fixed. The fixing method can be OCA bonding (the OCA at the position of the through hole 12 of the upper glass needs to be hollowed out), and then each through hole 12 is respectively plugged into each cover plate 3, that is, the cover plate 3 with the adhesive bonded is put into the through hole 12 for fixing, and then the black ink is silk-screened + the ink is cured, and the clamping and fixing of the cover plate 3 and the clamp 1 is completed.

[0065] In some specific embodiments, a removable adhesive is provided between the cover plate 3 and the lower sheet 11, and the removable adhesive can be separated from the cover plate 3 or the lower sheet 11 when subjected to a temperature within a set range. In order to allow the liquid crystal display assembly to be freely taken out after the liquid crystal display assembly is formed, the removable adhesive can be separated from the cover plate 3 or the lower sheet 11 by applying a temperature within a set range to the removable adhesive.

[0066] In some specific embodiments, when the cover plate 3 is connected to the lower sheet 11 by the peelable adhesive, the edge of the peelable adhesive does not exceed the edge of the lower sheet 11. This is to prevent the peelable adhesive from being too large and causing the edge of the peelable adhesive to contact the through hole 12, so that the peelable adhesive is bonded to the inner wall of the through hole 12.

[0067] In some specific embodiments, the shapes of the clamp 1 and the clamp 2 match or the surfaces of the two clamps are provided with matching placement areas for placing the cover plate 3 or the display module 4. Such a setting is to prevent the position deviation of the clamp 1 and the clamp 2 from occurring when they are attached.

[0068] Example 2

[0069] The connection structure between the small-size cover plate and the display module provided in Example 1 is further optimized, and the specific optimization direction is: the surface edge of the clamp 1 is provided with alignment posts 5 (preferably 4), and the surface edge of the clamp 2 is provided with alignment holes 6 (preferably 4), and the alignment posts 5 are connected with the alignment holes 6 to guide each cover plate 3 to fit correspondingly with each display module 4.

[0070] This arrangement is to ensure that when the clamp 1 and the clamp 2 are fitted together, the alignment posts 5 can play a guiding role by connecting with the alignment holes 6, so that all the cover plates 3 and the display modules 4 can be fitted together correspondingly within the same time period.

[0071] Example 3

[0072] The connection structure between the small-sized cover plate and the display module provided in Example 1 or 2 is further optimized. Since the cover plate 3 is small in size, it will not be scratched against the inner wall of the through hole 12 when inserted into the through hole 12. Therefore, the specific optimization direction is:

[0073] In some specific embodiments, a plurality of accommodating areas 7 are provided on the surface of the clamp 1 , and each accommodating area 7 is respectively provided corresponding to each cover plate 3 , and the accommodating area 7 can accommodate and restrict the cover plate 3 .

[0074] In some specific embodiments, the accommodating area 7 includes an annular groove 8 (the position of which is the same as that of the through hole 12) arranged on the surface of the clamp 1, and the inner side wall of the annular groove 8 is provided with multiple abutment points 9, each of which limits the cover plate 3 by abutting against the side wall of the cover plate 3.

[0075] In some specific embodiments, the annular groove 8 is arranged along the edge of the cover plate 3 , and the height of the annular groove 8 is below the cover plate 3 . This arrangement is to allow the cover plate 3 to expose the annular groove 8 .

[0076] In some specific embodiments, the thickness of the abutment point 9 is less than the thickness of the cover plate 3. This setting is to reduce the thickness of the abutment point 9 so that the end of the abutment point 9 will not contact the peelable glue on the cover plate 3, and it can also prevent the abutment point 9 from exceeding the surface of the cover plate 3.

[0077] The size of the annular groove 8 is larger than the cover plate 3, so there will be no adhesion when the cover plate 3 is placed in the annular groove 8. At the same time, when the cover plate 3 is placed in the annular groove 8, each abutment point 9 can limit the cover plate 3 by abutting against the side wall of the cover plate 3.

[0078] The use process of the small-size cover plate and display module connection structure provided by the utility model is as follows:

[0079] First, the upper sheet 10 and the lower sheet 11 are fixed together, and the fixing method can be OCA bonding. Then, the cover plate 3 with the adhesive bonded is placed in the through hole 12 for fixing. Then, black ink is screen-printed + the ink is cured, and the clamping and fixing of the cover plate 3 and the clamp 1 is completed.

[0080] Then, the clamp 1 and the clamp 2 are laminated together. At this time, each cover plate 3 and each display module 4 are laminated together correspondingly to form a liquid crystal display assembly.

[0081] After the bonding is completed, take out the TLI component (i.e., liquid crystal display component) and remove the high-temperature peelable adhesive.
