Description

Technical Field

[0001] The utility model relates to the technical field of LED display, and particularly relates to a display device and an electronic device. Background Art

[0002] Traditional LED display devices for electronic products are usually manufactured using modules. After manufacturing the LED modules, the modules are then installed on the circuit board of the electronic product to achieve the display function. During the manufacturing process of the LED module, a potting process is required. Its advantages are as follows: The potted LEDs can not only meet higher requirements in terms of sealing and mechanical stability, but sometimes they can also improve the optical properties such as light color and dispersion better than using a housing, provided that appropriate potting materials are selected.

[0003] In the related art, in order to obtain better and more flexible display effects, the traditional practice of having to use modules to manufacture the LED display structure has been changed. Instead, multiple LEDs are directly fixed on the circuit board, and then a bracket is arranged on the circuit board, and a light-emitting surface is arranged on the bracket. The bracket of the LED serves to block each LED and prevent crosstalk between the LEDs. A light guide hole is formed inside the bracket, the LED is placed in the light guide hole, and a potting space is formed in the light guide hole for pouring in the colloid for encapsulating the light source. These colloids also have functions such as light guiding and light homogenization. In order to still use the potting technology, it is necessary to ensure the sealing between the bracket and the circuit board. Otherwise, during the vacuum pumping process, the potting glue is very likely to leak out from the small gap between the outer part of the bracket and the circuit board. The bracket can be fixed to the circuit board using an adhesive fixative, and the gap between the outer part of the bracket and the circuit board can be sealed. In order to ensure the necessary sealing effect, the adhesive needs to have a sufficient thickness to ensure the sealing effect. However, it has been found in practice that such a fixing method will cause a crosstalk space with the same height as the adhesive thickness between the bracket and the circuit board due to the thickness of the adhesive, and crosstalk is likely to occur between the light guide holes due to the existence of the crosstalk space. Summary of the Utility Model

[0004] One of the purposes of the utility model is to provide a sealing structure between the bracket and the circuit board, which can prevent the potting glue inside the bracket from leaking and prevent crosstalk between light sources.

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0032] Please refer to Figure 1 , a display device, including a lamp board 1 and a bracket 2. Among them, the bracket 2 is a cuboid bracket; the lamp board 1 includes a circuit board 11 and an LED lamp 12 fixed on the circuit board 11.

[0033] In other embodiments of the present utility model, the bracket 2 can also be a cylindrical bracket or a bracket of any other shape, which is not limited herein.

[0034] Please refer to Figure 2 , the bracket 2 has a bracket outer part 21. The bracket outer part 21 refers to the outermost ring structure of the bracket 2, and all the LED lamps 12 are arranged within the bracket outer part 21. The part of the bracket 2 except the bracket outer part 21 is called the bracket inner part 20. The bracket inner part 20 has a light guide hole 22 for accommodating the LED lamp 12, and the bracket inner part 20 has a lower edge 201 that can block the light guide hole 22 and abut against the circuit board 11. In this way, it is possible to prevent the generation of light leakage gaps between the LED lamps 12, thereby preventing the occurrence of crosstalk between the LED lamps 12.

[0035] The bracket inner part 20 usually has one or more light guide holes 22. Each light guide hole 22 accommodates an LED lamp 12 and prevents crosstalk between the LED lamps 12 in different light guide holes. In the embodiments of the present utility model, one LED lamp 12 illuminates one light guide hole 22. In other embodiments of the present utility model, two or more LED lamps 12 can also be used to illuminate the light guide hole 22 to achieve a better display effect. The light guide hole 22 can be freely designed according to the display pattern that meets the design requirements. In the embodiments of the present utility model, the light guide holes 22 of the LED lamps 12 form two digital display patterns formed by a plurality of light guide holes 22 and another five square display patterns formed by single light guide holes 22 (see Figure 3 ).

[0036] There is an area within the region surrounded by the outer part 21 of the bracket where there is no display by the LED lamp 12. For these areas, a groove 203 is provided at the lower edge 201 of the inner part 20 of the bracket, which helps to reduce the material loss of the bracket 2.

[0037] The bracket 2 is provided with a cover part 3 for displaying patterns.

[0038] In this embodiment, the cover part 3 is a cover plate 3a. The outer part 21 of the bracket has an upper end part 212 higher than the inner part 20 of the bracket. At this time, the bracket has an opening 23 (see Figure 1 ). In this way, it is beneficial for the potting glue to be poured into the bracket 2 from the opening 23, spread within the opening 23, and then gradually fill all the light guide holes 22. The cover plate 3a has a plate body 30. The bottom of the plate body 30 is fixedly connected to the upper end part 212. And the inner side of the cover plate 3a extends downward to form a mating end part 31. There is a mating gap between the mating end part 31 and the top 202 of the inner part 20 of the bracket. The outer side of the mating end part 31 has a mating surface 32. The mating surface 32 mates with the inner wall 213 of the outer part 21 of the bracket at the opening 23, restricting the cover plate 3a from deflecting in the horizontal direction. The inner part 20 of the bracket is provided with a mating rib 204 disposed on the inner part 20 of the bracket and capable of blocking the light guide hole 22. The top of the mating rib 204 is provided with a trapezoidal tip 205. And the mating end part 31 has a trapezoidal groove 35 adapted to the trapezoidal tip 205, such that the trapezoidal tip 205 just sinks into the mating end part 31. In this way, it is beneficial to achieve a labyrinth seal between the cover plate 3a and the bracket 2, so that the light paths formed by including the light guide holes 22 do not interfere with each other and avoid light leakage.

[0039] It should be noted that the trapezoidal tip 25 and the mating groove 34 are not necessarily trapezoidal and not necessarily sharp. They can also be tips of other shapes such as triangular, arc-shaped, rectangular, etc., as long as they cooperate with each other.

[0040] The cover plate 3a has display holes 33 corresponding to and adapted to the light guide holes 22 for displaying patterns. The display holes 33 penetrate the cover plate 3a. The display holes 33 and the light guide holes 22 together form a light path.

[0041] The other end faces of the mating end part 31 that have nothing to do with the light guide holes 22 can extend upward from the bottom to form recesses 34 to avoid material loss of the cover plate 3a. In this embodiment, the cover plate 3a and the bracket 2 are bonded and fixed using an adhesive on the plate body 31. It should be noted that in other embodiments, the cover plate 3a and the bracket 2 can be fixed by other fixing methods such as bonding with double-sided tape, screw fixing, snap fixing, interference fit, etc. according to design requirements.

[0042] In other embodiments, since the display hole 33 has the function of displaying a pattern, the light guide hole 22 does not have to be adapted to the display hole. Thus, the light guide hole 22 can be of a simple and easy-to-produce shape, such as a round hole or the like. Generally speaking, to ensure a good display effect, the display hole 33 is not larger than the light guide hole 22.

[0043] In addition, it should be noted that in some embodiments, there may be no cover plate 3a. If there is a cover plate 3a, in some aspects, it is to make the upper end portion 212 of the outer side portion extend beyond the inside of the bracket 20, so that the opening 23 formed by the outer side portion 21 of the bracket can allow the potting adhesive to be poured into the opening 23 and then gradually fill into each light guide hole 22. This is conducive to filling all the light guide holes 22 with the adhesive by using single-hole potting. If there is no cover plate 3a, the upper end portion 212 of the outer side portion 21 of the bracket can be flush with the top 202 of the inner side portion 20 of the bracket. At this time, it is difficult to pour the potting adhesive into all the light guide holes 22 through one opening, but the potting adhesive can be poured into each light guide hole 22 separately.

[0044] Please refer to Figure 4 , for the convenience of display, in other embodiments of the present embodiment, the cover portion 3 can be a display diaphragm 3b for displaying a pattern. The display device can include a mounting groove for placing and fixing the display diaphragm 3b. At this time, the display diaphragm 3b and the mounting groove can be fixed by fixing methods such as bonding with an adhesive or fixing with double-sided tape.

[0045] The display diaphragm 3b can be made of a light-transmitting material or a semi-light-transmitting material. When the display diaphragm 3b is made of a semi-light-transmitting material, the pattern can be defined by the shape of the light guide hole. When the display diaphragm is made of a light-transmitting material, the display diaphragm 3b is made into a pattern by screen printing. At this time, the light guide hole does not have to be designed according to the pattern that meets the design requirements, but can be of a simple and easy-to-produce shape, such as a round hole or the like. It should be understood that generally speaking, the size of the pattern displayed by the display diaphragm made of a transparent material is not larger than the light guide hole.

[0046] It should be understood that in some embodiments, the cover plate 3a and the display diaphragm 3b can be replaced by other cover portions having the function of displaying a pattern.

[0047] In addition, please refer to Figure 3 , there can be two positioning round holes 13 on the circuit board 11, which is convenient for positioning the circuit board 11 in the jig. An auxiliary jig can be used to position and assemble the bracket 2 and the circuit board 11.

[0048] To ensure the sealing between the bracket 2 and the circuit board 11, and to prevent the formation of a gap with the same height as the bonding thickness between the circuit board 11 and the outer part 21 of the bracket when the adhesive is directly applied between them, which may cause light leakage between the light guide holes 22, the present utility model adopts the technical solution of forming a receiving space between the lower end of the outer part 21 of the bracket and the circuit board 11, and using the connecting part to be cured and filled in the receiving space to achieve the fixation and sealing between the bracket and the circuit board.

[0049] As Figure 2 shown, in the preferred embodiment of this embodiment, the receiving space is the gap formed between the receiving groove and the circuit board. For example, the lower end 211 has an outer part 211A, a middle part 211B, and an inner part 211C. The inner part 211C and the outer part 211A of the lower end 211 are in contact with the circuit board 11, and the middle part 211B of the lower end 211 is recessed to form a receiving groove 211B. At this time, the receiving space is the space between the receiving groove 211B and the circuit board 11. As Figure 2 shown, the groove is in a regular right-angled shape, but the groove shape is not limited to this, as long as it can form a certain receiving space inside the lower end 211 (the middle part 211B).

[0050] The connecting part is an adhesive 210a (not specifically shown in the figure). During assembly, the adhesive 210a can be placed in the receiving groove 211B, and then the circuit board 11 and the bracket 2 can be positioned and fixed using an auxiliary jig. Or the adhesive 210a can be first applied on the circuit board 11, and then the bracket 2 can be connected to the circuit board 11 in alignment. The above-mentioned adhesive 210a can be various colloids commonly used in the electronic industry, for example. The inner part 20 of the bracket has a lower edge 201 that can block the light guide holes 22 and is in contact with the circuit board 11. Based on this and the aforementioned technical solution, it can not only ensure the sealing performance between the bracket 2 and the circuit board 11, preventing the potting glue from leaking, but also make the bracket 2 and the circuit board 11 fit tightly, so that the light guide holes 22 do not interfere with each other, thus eliminating the risk of light leakage between the LED lights 12.

[0051] The above-mentioned adhesive 210a can use a colloid with strong fluidity or a colloid with poor fluidity. It is necessary to ensure that the receiving groove 211B is sufficient to accommodate the colloid, and the coating position of the colloid is completely within the receiving groove 211B. When using a colloid with strong fluidity, it is preferred to first apply the colloid in the receiving groove 211B, and then connect and fix the bracket 2 to the circuit board 11, so as to use the colloid flowing onto the circuit board 11 to achieve the fixation and sealing between the bracket 2 and the circuit board 11. When using a colloid with poor fluidity, it is preferred to first apply the colloid on the circuit board 11, and then connect the bracket 2 to the circuit board 11 in alignment, so as to use the fitting between the inner wall of the receiving groove 211B and the colloid to achieve the fixation and sealing between the bracket 2 and the circuit board 11.

[0052] Please refer to Figure 5 Based on the above embodiments, the connecting portion may be a protrusion 210b formed by the accommodating groove 211B extending downward. As shown in the figure, the bracket 2 can be positioned and assembled downward under the action of an ultrasonic welding machine, and the protrusion 210b can be finally melted and solidified under the action of ultrasonic waves and then joined to the circuit board 11, so as to realize the fixation and sealing between the bracket 2 and the circuit board 11. The protrusion 210b may be, for example, a triangular protrusion. In this embodiment, the protrusion is preferably an equilateral triangular protrusion 210b. In the design stage, the tip height of the protrusion 210b can be immersed into the circuit board between 0.3 mm and 0.5 mm, and the preferred immersion height is 0.3 mm. It should be noted that the protrusion 210b is not necessarily triangular, that is, the top of the protrusion does not have to be sharp. In fact, as long as the protrusion can generate local high temperature under the action of ultrasonic waves, melt it and finally solidify into a shape, it should be understood that it is within the protection scope of the present invention.

[0053] Please refer to Figures 6 - 7 In some embodiments, the accommodating space is the gap formed between the accommodating concave platform and the circuit board. For example, the lower end 211 of the outer part 21 of the bracket has an inner part 2112 and an outer part 2111. The inner part 2112 abuts against the circuit board 11, and there is a distance between the outer part 2111 and the circuit board 11, thereby forming an accommodating concave platform. The outer part 211 of the bracket also has a wall surface 2113 connecting the outer part 2111 and the inner part 2112. At this time, the accommodating space is the gap formed between the accommodating concave platform and the circuit board, that is, the space formed by the outer part 2111, the wall surface 2113 and the circuit board 11. As Figures 6 - 7 shown, the concave platform is a regular right-angled shape, but the shape of the concave platform is not limited to this, as long as it can form a certain distance between the outer part 2111 of the lower end 211 of the outer part 21 of the bracket and the circuit board.

[0054] Please refer to Figure 6 In this embodiment, the connecting portion may be an adhesive 210c (not specifically shown in the figure). When using the adhesive 210c as the connecting portion, the adhesive 210c can be pre-coated on the circuit board 11 corresponding to the accommodating concave platform 211B by a dispensing machine, or coated on the outer part 2111 (coated on the outer part 2111 after placing the bottom end of the bracket 2 upward), and then the bracket 2 is loaded.

[0055] It should be understood that when using the adhesive 210c as the connecting part, it is more beneficial to use a colloid with poor fluidity to prevent the colloid from escaping due to the influence of gravity and losing the bonding effect. Therefore, in this embodiment, it is best to use a colloid with poor fluidity for the adhesive 210c. At this time, the accommodating space provides a large space margin for the adhesive 210c. Even if the amount of the adhesive is relatively large, the adhesive 210c can leak to the outside of the bracket 2, so as to ensure that there is no gap between the bracket 2 and the circuit board 11 due to the adhesive.

[0056] Please refer to Figure 7 , on the basis of the above embodiment, the connecting part can be a protrusion 210d formed by the outer part 2111 extending downward. As shown in the figure, the bracket 2 can be positioned and assembled downward under the action of an ultrasonic welding machine, and the protrusion 210d can be finally melted and solidified under the action of ultrasonic waves and then joined to the circuit board 11, so as to realize the fixation and sealing between the bracket 2 and the circuit board 11. The shape of the protrusion at the design stage is as described above and will not be elaborated here.

[0057] Please refer to Figures 8 - 9 , in some embodiments, there is a distance between the lower end portion 211 and the circuit board 11. At this time, the accommodating space is the gap formed between the lower end portion 211 and the circuit board 11.

[0058] Please refer to Figure 8 , in this embodiment, the connecting part can be an adhesive 210e (not specifically shown in the figure). When using the adhesive 210e as the connecting part, the adhesive 210e can be pre-coated on the circuit board 11 corresponding to the lower end portion 211 by using a dispensing machine, or coated on the lower end portion 211 (coated on the lower end portion 211 after placing the bracket 2 with the bottom end facing up), and then the bracket 2 is installed.

[0059] It should be understood that when using the adhesive 210e as the connecting part, it is more beneficial to use a colloid with poor fluidity to prevent the colloid from escaping due to the influence of gravity and losing the bonding effect. Therefore, in this embodiment, it is best to use a colloid with poor fluidity for the adhesive 210e. In this embodiment, the lower end portion 211 provides sufficient space margin for the adhesive 210e. Even if the amount of the adhesive is relatively large, it can leak to the inside and outside of the bracket 2, so as to ensure that there is no gap between the bracket 2 and the circuit board 11 due to the adhesive 210e.

[0060] Please refer to Figure 9, on the basis of the above embodiments, the connecting portion may be a protrusion 210f formed by the lower end portion 211 extending downward. As shown in the figure, the bracket 2 can be positioned and assembled downward under the action of an ultrasonic welding machine, and the protrusion 210f can be finally melted and solidified under the action of ultrasonic waves and then joined to the circuit board 11, so as to realize the fixation and sealing between the bracket 2 and the circuit board 11. The shape of the protrusion in the design stage is as described above and will not be elaborated here.

[0061] In other embodiments of the present invention, the LED lamp may be other light sources such as lamp beads, Mini LEDs or their combinations.

[0062] The present invention also provides an electronic device, which includes a display device, and the specific structure of the display device refers to the above embodiments. Since this electronic device adopts all the technical solutions of the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.
