Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a protection bracket and a molding method thereof, a protection module and a display module. Background Art

[0002] At present, in order to compress the product frame and increase the display area, the DP (Data Process) side of OLED (Organic Light-Emitting Diode) products will adopt a curved design. However, the curved part formed by the DP (Data Process) side is very fragile, so it is very easy to cause problems such as poor line after being hit. In order to prevent the curved part from being damaged due to accidental touch during picking or impact during transportation, a protective bracket needs to be designed to protect the curved part.

[0003] In the related art, the protective bracket is made of PC material by injection molding. However, this protective bracket still has shortcomings. Summary of the invention

[0004] In view of the above problems, the present application provides a protective bracket and its molding method, a protective module and a display module, which can not only reduce the thickness of the protective bracket to effectively reduce the compression of the tray space, but also reduce the mold opening and revision cycle to reduce costs.

[0005] In the first aspect, an embodiment of the present application provides a protective bracket, which is used to protect a display module. The display module includes a display screen and a cover plate. The display screen has a display portion, a binding portion, and a bent portion connecting the display portion and the binding portion, which are arranged opposite to each other. The cover plate covers the display portion. The protective bracket is a blister molded bracket. The protective bracket includes: a bracket body, including a main body and an arm portion connected to the main body, the main body portion is used to separate and cover the electronic components of the binding portion, wherein the arm portion is formed with a first convex bulge protruding from the bracket body, and the first convex bulge and the arm portion form a protective cavity for accommodating the bent portion.

[0006] In the above technical solution, by designing the protective bracket as a blister molding bracket, on the one hand, compared with injection molding, the mold opening and revision cycle can be reduced to reduce costs. On the other hand, compared with injection molding, the material of the protective bracket will be stretched and extended to a certain extent during the blister molding process, resulting in its thickness becoming relatively thinner, thereby reducing the thickness of the protective bracket in the thickness direction, thereby effectively reducing the compression of the tray space. In addition, the first convex bump can strengthen the strength of the arm, thereby reducing the thickness of the arm while ensuring the strength of the arm. In addition, when the protective bracket is assembled with the display module to form a display module, the main body and the binding portion are spaced apart and cover the electronic components of the binding portion to protect the electronic components of the binding portion, and the first convex bump and the arm portion form a protective cavity for receiving the bent portion to protect the bent portion.

[0007] In some embodiments of the first aspect, the protection bracket further includes a fixing portion and a connecting portion, the fixing portion is used to be connected to the non-display side of the display module, and the fixing portion is connected to the main body via the connecting portion.

[0008] In some embodiments of the first aspect, in a thickness direction of the display screen, the fixing portion is closer to the display screen than the bracket body.

[0009] In the above technical solution, since the fixing part is connected to the main body via the connecting part, and the fixing part is closer to the display screen than the bracket body, the connection distance between the fixing part and the non-display side of the display module can be reduced when the fixing part is connected to the non-display side of the display module. Therefore, a raising structure is provided on the non-display side of the display module to be connected to the fixing part.

[0010] In some embodiments of the first aspect, the arm is provided in plurality.

[0011] In some embodiments of the first aspect, the plurality of arms are spaced apart to form a plurality of avoidance grooves, and the plurality of avoidance grooves expose at least a portion of the cover plate. The avoidance grooves expose a portion of the cover plate so as to facilitate fixing the exposed portion of the cover plate to the fixed end of the tray.

[0012] In some embodiments of the first aspect, a reinforcement structure is provided on the connecting portion, and the reinforcement structure also connects the fixing portion and the main body.

[0013] The reinforcement structure in the above technical solution can increase the connection strength between the fixing part and the main body, thereby reducing the risk of the connection part breaking due to force or vibration.

[0014] In some embodiments of the first aspect, the reinforcement structure includes a plurality of reinforcement ribs, each reinforcement rib connecting the fixing portion and the main body portion.

[0015] The reinforcing ribs in the above technical solution have a simple structure and are easy to shape.

[0016] In some embodiments of the first aspect, a groove structure is further provided on the main body, and the groove structure is used for grasping and positioning.

[0017] In the above technical solution, by providing a groove structure on the main body, the problem of poor grasping of the protective bracket formed by blister molding and cutting can be avoided due to poor edge precision. In addition, on the one hand, the groove structure can be directly formed by cutting, which is conducive to simplifying the structure of the blister mold to reduce the difficulty and cycle of developing the blister mold; on the other hand, the groove structure will not increase the thickness of the protective bracket.

[0018] In some embodiments of the first aspect, the groove structure opens at a periphery of the main body.

[0019] In the above technical solution, by setting the groove structure to open at the periphery of the main body, on the one hand, the length of the cutting line can be reduced when the area of ​​the groove structure is the same; on the other hand, it can be more convenient to grasp.

[0020] In some embodiments of the first aspect, a plurality of second convex humps are formed on the main body, and each second convex hump protrudes from the bracket main body at the side where the first convex hump is located.

[0021] In the above technical solution, on the one hand, each second bulge can strengthen the strength of each main body part, thereby reducing the thickness of the main body part while ensuring the strength of the main body part. Compared with injection molding, the material of each second bulge will be stretched and extended to a greater extent during the vacuum molding process, resulting in its thickness becoming relatively thinner, which is beneficial to reduce the thickness of the protective bracket in the thickness direction, thereby effectively reducing the compression of the tray space.

[0022] In some embodiments of the first aspect, a buffer is fixedly provided on a side of each second convex bump facing away from the main body, and the buffer has a preset elastic deformation force.

[0023] In the above technical solution, during the assembly process of the protection bracket and the display module or during the handling and transportation of the display module, the protection bracket vibrates due to force or inertia. When the vibration causes each buffer component to be elastically compressed and deformed, each buffer component can buffer and absorb the impact of each second convex bump on the display module, thereby avoiding direct collision between each second convex bump and the display module.

[0024] In a second aspect, the present application provides a method for forming a protective bracket, which comprises the following steps:

[0025] The sheet is heated to a softening temperature;

[0026] The softened sheet is subjected to vacuum forming to obtain a rough blank;

[0027] The rough blank is cut to obtain the protective bracket of any embodiment of the first aspect.

[0028] In a third aspect, the present application provides a protection module, comprising: a protection bracket provided in any embodiment of the first aspect; and a connection structure connected to the protection bracket and used to connect to the non-display side of the display module.

[0029] The above technical solution connects the protection bracket to the non-display side of the display module through the connection structure, which facilitates the assembly of the protection bracket and the display module to improve the assembly efficiency.

[0030] In some embodiments of the second aspect, a side of the connection structure facing away from the protection bracket is removably covered with a release film.

[0031] In the above technical solution, the release film can prevent the connection structure of the protection module from failing during storage, transfer, transportation, etc.

[0032] In some embodiments of the second aspect, at least one side of the release film extends beyond the boundary of the connection structure, so as to facilitate the removal of the release film so that the connection structure can connect the protection bracket to the non-display side of the display module.

[0033] In some embodiments of the second aspect, the connecting structure is connected to the fixing portion.

[0034] In a fourth aspect, the present application provides a display module, which includes: a display module, including a display screen and a cover plate, the display screen having a display portion, a binding portion and a bent portion connecting the display portion and the binding portion arranged in opposite directions, and the cover plate covering the display portion; a protective bracket provided in any embodiment of the first aspect, the first convex bump, the arm portion and the cover plate forming a protective cavity for accommodating the bent portion, the main body portion is separated from the binding portion and covers the electronic components of the binding portion; a connecting structure, connecting the protective bracket to the non-display side of the display module.

[0035] In the above technical solution, on the one hand, the first convex bump and the arm portion are used to form a protective cavity for accommodating the bent portion with the cover plate, so that the side of the bent portion can be protected; on the other hand, the main body portion is separated from the binding portion and the electronic components of the binding portion are covered to protect the electronic components of the binding portion, thereby preventing the electronic components of the binding portion from being damaged during the turnover, lighting test, packaging and shipment of the display module.

[0036] In some embodiments of the fourth aspect, the cover plate includes an upper surface and a lower surface facing each other and a side surface connecting the upper surface and the lower surface, the display portion is opposite to the lower surface, each first protrusion is arranged at a preset interval from the side surface, and the end surface of each first protrusion away from the arm portion is between the plane where the upper surface is located and the plane where the lower surface is located.

[0037] The above technical solution, on the one hand, can avoid the first convex bump and the cover plate from rubbing against each other due to vibration caused by force during the assembly of the protection bracket and the display module or during the handling and transportation of the display module, thereby preventing the poor appearance of the display module. On the other hand, by arranging the end face of the first convex bump away from the bracket body to be between the plane where the upper surface is located and the plane where the lower surface is located, it can avoid interference between the protection bracket and the tray when the display module is packaged in the tray. In addition, by arranging the first convex bump and the side face at a preset spacing and by arranging the end face of the first convex bump away from the bracket body to be between the plane where the upper surface is located and the plane where the lower surface is located, the first convex bump can surround the curved portion, thereby preventing damage to the curved portion from external forces perpendicular to the side direction.

[0038] In some embodiments of the fourth aspect, the connecting structure is connected to the fixing portion.

[0060] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0062] In the present application, the term "parallel" includes not only the absolutely parallel situation, but also the roughly parallel situation conventionally recognized in engineering; meanwhile, "vertical" includes not only the absolutely vertical situation, but also the roughly vertical situation conventionally recognized in engineering.

[0063] At present, in order to compress the product frame and increase the display area, the DP (Data Process) side of OLED (Organic Light-Emitting Diode) products will adopt a curved design. However, the curved part formed by the DP (Data Process) side is very fragile, so it is very easy to cause problems such as poor line after being hit. In order to prevent the curved part from being damaged due to accidental touch during picking or impact during transportation, a protective bracket needs to be designed to protect the curved part.

[0064] In the related art, the protective bracket is injection molded from PC material. Due to the strength and injection molding process requirements, the main body thickness of the PC material injection molded protective bracket must be no less than 1.2mm, and it is used in conjunction with double-sided tape, PU foam, release film, and transfer film, and attached to the product to form a protection system for the curved part. However, this protective bracket has the following disadvantages: large thickness in the Z-axis direction, which will compress the tray space; poor toughness, prone to breakage, deformation and other undesirable phenomena; cannot transmit light, and after being assembled to the display module, it will shield the curved part, affecting the appearance inspection of the product; a new injection mold is required, and the mold opening and revision cycle is long and the cost is high.

[0065] Based on the above considerations, the present application designs a protective bracket.

Figure 6 A top view of a display module provided in some embodiments of the present application; Figure 7 for Figure 6 A bottom view of the display module is shown; Figure 8 for Figure 6 A partial side view of the display module is shown.

That is, each second convex bump 115 protrudes from the bracket body 11 at the first side 1A.

[0090] Each second convex bump 115 is formed by stretching and extending a portion of the main body 111 toward the first side 1A under negative pressure during the vacuum forming process.
