Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figures 1 to 2 The present invention provides a fixture device including a positioning fixture 100 and a forming mold 200, wherein the positioning fixture 100 is provided with a positioning cavity 110; the forming mold 200 is made of a flexible material, the forming fixture is provided with a forming cavity 220, and the forming mold 200 is placed in the positioning cavity 110.

[0030] In practical applications, after the display panel 400 is placed into the molding cavity 220, the operator pours encapsulating adhesive into the molding cavity 220 again. The encapsulating adhesive needs to submerge the upper surface of the display panel 400 and the pins of the LED beads 410, and may partially or not submerge the surface of the LED beads 410. After the encapsulating adhesive solidifies, it completes the encapsulation of the display panel 400, thus obtaining the desired display panel 400. Then, the operator removes the encapsulated display panel 400 from the molding mold 200.

[0031] Understandably, the molding mold 200 is made of a flexible material, and the encapsulating adhesive is not bonded to the molding mold 200. This design allows for easy removal of the molding mold 200 from the display panel 400 by operators after the encapsulating adhesive has solidified in the molding cavity 220, minimizing the risk of damage to the display panel 400. The positioning fixture 100 can be made of a material with a certain degree of hardness. When the molding mold 200 is placed in the positioning cavity 110, the positioning fixture 100 can maintain the shape of the molding mold 200, thus ensuring that the display panel 400 can be placed flat within the molding cavity 220. Therefore, the encapsulating adhesive can be cured smoothly on both sides of the display panel 400, resulting in a relatively flat encapsulated display panel 400.

[0032] In some embodiments, please refer to Figures 1 to 2 The fixture device also includes a fixture cover 300, which is fastened to the positioning fixture 100 and pressed against the surrounding plate 210 of the forming mold 200. Specifically, when the forming mold 200 is placed in the positioning cavity 110 of the positioning fixture 100, the fixture cover 300 is fastened to the top of the positioning fixture 100. At this time, the fixture cover 300 is pressed against the surrounding plate 210 of the forming mold 200, thereby flattening the forming mold 200. Simultaneously, the top of the fixture cover 300 has a placement opening 310, the size of which is greater than or equal to the size of the opening of the forming cavity 220. For example, the size of the placement opening 310 is set to be consistent with the size of the opening of the forming cavity 220. Therefore, after the fixture cover 300 flattens the forming mold 200, the operator can insert the display panel 400 into the forming cavity 220 of the forming mold 200 through the placement opening 310.

[0033] Understandably, by setting the fixture cover 300, the fixture cover 300 ensures that the molding mold 200 can be placed flat in the positioning cavity 110, thereby ensuring the flatness of the molding cavity 220, and thus ensuring that the display panel 400 can be placed flat in the molding cavity 220. As a result, the encapsulating adhesive can be solidified flatly on both sides of the display panel 400.

[0034] In other possible embodiments, the fixture cover 300 may not need to be provided with the placement opening 310. Before the fixture cover 300 is fastened to the positioning fixture 100, the operator can place the display panel 400 in the molding cavity 220 and pour encapsulating glue into the molding cavity 220, and then fasten the fixture cover 300 to the positioning fixture 100.

[0035] Furthermore, one of the positioning fixture 100 and the fixture cover 300 is provided with a positioning post 130, and the other is provided with a positioning hole 320. The positioning post 130 is inserted into the positioning hole 320. Specifically, the positioning fixture 100 has positioning posts 130 at the four corners of its top, and the fixture cover 300 has positioning holes 320 at the four corners. When the fixture cover 300 is fastened onto the positioning fixture 100, the positioning posts 130 are inserted into the positioning holes 320, thereby ensuring that the fixture cover 300 accurately presses the molding mold 200. As a result, the placement opening 310 on the fixture cover 300 is aligned with the opening of the molding cavity 220, making it convenient for the operator to place the display panel 400 into the molding cavity 220 through the placement opening 310 for surface sealing with encapsulating adhesive.

[0036] In some embodiments, please refer to Figures 2 to 4 The bottom of the molding cavity 220 is provided with a support portion 240, which is cylindrical in shape. The height of the support portion 240 is set between 3mm and 20mm, for example, 3mm, 5mm, 8mm, 10mm, 15mm, 20mm, etc., depending on the actual required encapsulation thickness. The support portion 240 is used to support the display panel 400, so that a gap is formed between the display panel 400 and the bottom of the molding cavity 220.

[0037] With this configuration, the support portion 240 supports the display panel 400 upwards when it is placed in the molding cavity 220, thus maintaining a certain distance between the display panel 400 and the bottom of the molding cavity 220. This prevents some of the encapsulating adhesive from being squeezed onto the upper side of the display panel 400 when it is placed in the molding cavity 220. Therefore, the lower side of the display panel 400 has a sufficient amount of encapsulating adhesive to form a sufficiently thick encapsulating adhesive layer, thereby effectively encapsulating the back side of the display panel 400.

[0038] In some embodiments, please refer to Figures 2 to 4The bottom of the molding cavity 220 has multiple strip-shaped protrusions 230 arranged side by side, that is, the strip-shaped protrusions 230 are arranged parallel to each other. The strip-shaped protrusions 230 are used to be inserted into the strip-shaped through holes 420 of the display panel 400, and the support part 240 is located between adjacent strip-shaped protrusions 230. Specifically, the display panel 400 has strip-shaped through holes 420 arranged side by side. When the display panel 400 is placed in the molding cavity 220, the strip-shaped protrusions 230 fill the strip-shaped through holes 420. With this arrangement, the encapsulating adhesive will not fill the strip-shaped through holes 420 when it solidifies, so that the display panel 400 retains the original strip-shaped through holes 420 for use as a transparent display panel 400.

[0039] In some embodiments, the molding die 200 is made of silicone material. It is understood that by using silicone material, the molding die 200 possesses a certain degree of elasticity and hardness, making it less prone to breakage and able to withstand certain pressure and impact forces, thus reducing the likelihood of damage from external forces in practical applications. Furthermore, silicone remains stable over a wide temperature range, generally allowing for long-term use at temperatures from -40°C to 230°C, and can withstand even higher temperatures for short periods.

[0040] Furthermore, the encapsulating adhesive is made of epoxy resin, and the molding mold 200 is made of silicone material; the two do not adhere to each other and can solidify naturally. When the encapsulating adhesive is in a cured state, workers can easily separate the display module from the molding mold 200.

[0041] In some embodiments, please refer to Figure 2 , 3 and Figure 5 The bottom of the positioning fixture 100 is provided with an operating port 120 that extends through its inner and outer sides. The molding mold 200 is provided with a protrusion 250 that is embedded in the operating port 120. The bottom of the molding cavity 220 is provided with a relief groove 251 located in the protrusion 250. The relief groove 251 is used to accommodate the connector 430 on the back of the display panel 400.

[0042] It is understood that the bottom of the positioning fixture 100 is provided with an operating port 120 that extends through its inner and outer sides. When it is necessary to remove the molding die 200 from the positioning cavity 110, the operator can press the molding die 200 outward through the operating port 120, thereby easily removing the molding die 200 from the molding cavity 220. Simultaneously, the molding die 200 is provided with a protrusion 250 that is embedded in the operating port 120, and the bottom of the molding fixture is provided with a relief groove 251 located in the protrusion 250. The back of the circuit board is provided with a connector 430 embedded in the relief groove 251. It is understood that, through the provision of the protrusion 250, the molding die 200 can be provided with a sufficiently deep relief groove 251 to accommodate the connector 430; at the same time, the connector 430 being located within the relief groove 251 effectively prevents encapsulating adhesive from entering the connector 430.

[0043] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
