DETAILED DESCRIPTION
[0020] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present application. Specifically, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should fall within the scope of protection of the present application.
[0021] It should be noted that similar reference numerals and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0022] The assembly structure of the OLED module in the prior art is as follows Figure 1As shown, the OLED module 1 generally includes a substrate 101, a light-emitting functional layer 102, and a packaging cover plate 103 for packaging the light-emitting functional layer 102 on the substrate 101. The OLED module 1 is usually assembled and connected with the bracket 2 through the packaging cover plate 103. The side of the bracket 2 for connection has a receiving groove for accommodating the OLED module 1. During assembly, the adhesive 3 is first applied to the bottom of the receiving groove, and then the OLED module 1 is placed in the receiving groove. The packaging cover plate 103 of the OLED module 1 is bonded to the bracket 2 through the adhesive 3, thereby achieving a fixed connection between the OLED module 1 and the bracket 2, that is, the stability of the connection between the OLED module 1 and the bracket 2 is completely dependent on the stability of the selected adhesive 3. However, the bonding stability of the adhesive 3 is often easily affected by environmental factors (such as high temperature, humidity, etc.), and the problem of loose bonding between the OLED module 1 and the bracket 2 is likely to occur, which causes the OLED module 1 to easily fall off from the bracket 2.
[0023] To solve the above problems, the present application provides an assembly structure of an OLED module. Figure 2 The assembly structure of the OLED module includes: an OLED module 1, a bracket 2 and a fixing member 4 for firmly connecting the OLED module 1 to the bracket 2; the fixing member 4 includes a fixed horizontal limiting portion 41 and a vertical limiting portion 42; the horizontal limiting portion 41 is fixed to the bracket 2 and is used to limit the OLED module 1 in the horizontal direction, and the vertical limiting portion 42 is used to apply a force along the vertical direction to the non-luminous area of the OLED module 1 to limit the OLED module 1 in the vertical and horizontal directions.
[0024] Specifically, the substrate 101 of the OLED module 1 has a luminous area and a non-luminous area on one side away from the packaging cover plate 103. The luminous area refers to the area corresponding to the light-emitting functional layer 102, and the non-luminous area surrounds the luminous area and refers to the area corresponding to the packaging cover plate 103. During assembly, one side of the packaging cover plate 103 is placed on the bracket 2.
[0025] The present application no longer uses adhesive 3 to fix the OLED module 1 on the bracket 2, but introduces a fixing member 4, which includes a horizontal limiting portion 41 and a vertical limiting portion 42. The two parts are fixed, and can be integrally formed or formed during the assembly process; wherein the horizontal limiting portion 41 is fixedly connected to the bracket 2, and can be fixed by auxiliary components during the assembly process, or can be fixed before assembly (such as integrally formed).
[0026] In the assembled structure, the horizontal limiting portion 41 of the fixing member 4 can limit the OLED module 1 in the horizontal direction from the side of the OLED module 1 (i.e., the side of the substrate 101 and the packaging cover plate 103), which can prevent the OLED module 1 from moving left and right or forward and backward on the bracket 2. The vertical limiting portion 42 of the fixing member 4 can apply downward pressure in the vertical direction to the OLED module 1 from the top surface of the OLED module 1 (i.e., the non-luminous area of the substrate 101), so as to cooperate with the bracket 2 to limit it in the vertical direction, which can limit the displacement of the OLED module 1 in the vertical direction. At the same time, since the vertical limiting portion 42 applies a certain pressure to the OLED module 1, it can also prevent the OLED module 1 from shaking in the horizontal direction to a certain extent, that is, the vertical limiting portion 42 can also limit the displacement of the OLED module 1 in the horizontal direction. When the assembly structure is vibrated or collided, this stable fixing method can ensure that the position of the OLED module is relatively stable, avoid damage to the OLED module due to displacement, and avoid problems such as poor contact, thereby ensuring the normal operation of the equipment.
[0027] The assembly structure of the OLED module provided by the present application can limit the OLED module in the horizontal and vertical directions through the cooperation of the horizontal limiting part 41 and the vertical limiting part 42 of the fixing part, prevent it from being displaced in the horizontal and vertical directions, and achieve a stable fixing effect; by acting the vertical limiting part 42 on the non-luminous area of the OLED module, it can not only reasonably utilize the non-luminous area, but also avoid any adverse effects on the luminous effect of the OLED module. Compared with the display abnormality (such as picture deformation, local display damage, etc.) that may be caused by acting on the luminous area, this method well protects the key functional parts of the OLED module and realizes effective assembly and fixation. In general, the assembly structure of the OLED module of the present application enhances the reliability and stability of the structure compared with the method of using adhesive to achieve fixation in the prior art.
[0028] Furthermore, a first buffer pad 5 is provided between the vertical limiting portion 42 of the fixing member 4 and the non-luminous area of the OLED module 1 .
[0029] Specifically, the first buffer pad 5 can prevent the vertical limit portion 42 of the fixing member 4 from hard contact with the OLED module 1 to prevent the screen from being broken, that is, the first buffer pad 5 can protect and fix the OLED module 1. Preferably, the first buffer pad 5 is a foam bonded to the non-luminous area of the OLED module 1, and is bonded to the non-luminous area of the substrate 101 before assembly.
[0030] Furthermore, the bracket 2 has a mounting groove for mounting the OLED module 1 ; the depth of the mounting groove is less than the height of the OLED module 1 ; and the horizontal limiting portion 41 of the fixing member 4 is in contact with the outer wall of the mounting groove.
[0031] Specifically, refer to Figure 2 The depth of the mounting groove on the bracket 2 is smaller than the height of the OLED module 1, so that the OLED module 1 can extend from the mounting groove, so that the horizontal limit portion 41 of the fixing member 4 can abut against the outer groove wall of the mounting groove and the side of the OLED module 1 to form a horizontal limit.
[0032] In this embodiment, the fixing member 4 is a lamp housing, a lampshade or a decorative frame structure, and its horizontal limit portion 41 and the vertical limit portion 42 are integrally formed, wherein the horizontal limit portion 41 includes an upper limit portion abutting against the side of the OLED module 1 and a lower limit portion adapted to the outer contour of the mounting groove, the top of the upper limit portion is bent and extends to the non-luminous area of the substrate 101 to form the vertical limit portion 42, and the lower limit portion is fixed to the bracket 2 by means of screw locking, clamping or riveting.
[0033] Figure 2 The assembly method of the first OLED module assembly structure shown is: first, place one side of the packaging cover plate 103 of the OLED module 1 into the mounting groove of the bracket 2, and the substrate 101 bonded with the first buffer pad 5 extends out of the mounting groove; then, place the fixing member 4 on the bracket 2, and make the horizontal limiting portion 41 of the fixing member 4 abut against the side surface of the OLED module 1 and the bracket 2, and the vertical limiting portion 42 presses down the first buffer pad 5 from above; finally, fix the fixing member 4 on the bracket 2 by locking, clamping or riveting.
[0034] In a preferred embodiment, a second buffer pad 6 is provided on the inner groove wall of the installation groove.
[0035] For details, please refer to Figure 3 , Figure 3 exist Figure 2 A second buffer pad 6 is added on the basis of the assembly structure of the first OLED module shown. The second buffer pad 6 can squeeze the OLED module 1 from the side, further preventing the OLED module 1 from being displaced in the horizontal direction; preferably, the second buffer pad 6 is provided on one side of the mounting groove, so as to facilitate the installation of the OLED module 1 into the mounting groove; preferably, the second buffer pad 6 is a foam bonded to the inner groove wall of the mounting groove.
[0036] Furthermore, the thickness of the second buffer pad 6 is greater than the clearance tolerance between the OLED module 1 and the inner wall of the mounting groove; the height of the second buffer pad 6 is greater than or equal to half the height of the OLED module 1 and less than or equal to the height of the OLED module 1 .
[0037] Specifically, the thickness of the second buffer pad 6 refers to its dimension in the horizontal direction, and the thickness dimension must be greater than the gap tolerance between the OLED module 1 and the inner groove wall of the mounting groove. For example, the gap tolerance between the mounting groove of the bracket 2 and the OLED module 2 is 0.1 mm, and the thickness of the second buffer pad 6 is selected to be 0.2 mm.
[0038] Specifically, the height of the second buffer pad 6 refers to its dimension in the vertical direction, which may be consistent with the depth of the installation groove or greater than the depth of the installation groove. If the height dimension is too small, it may not play a buffering protection role, and if the height dimension is too large, it may affect the limiting role of the vertical limiting portion 42 of the fixing member 4. Therefore, in this embodiment, it is required that the height dimension is not less than half of the height of the OLED module 1 at a minimum and not more than the height of the OLED module 1 at a maximum, for example, it may be 1 / 2, 2 / 3, 3 / 4 of the height of the OLED module 1, etc. Exemplarily, if the height of the OLED module 1 is 2 mm, the height of the second buffer pad 6 may be 1 mm, 1.3 mm, 1.5 mm, 1.7 mm, 1.9 mm, 2 mm, etc.
[0039] Figure 3 The assembly method of the second OLED module assembly structure shown is: first, the second buffer pad 6 is bonded to one side wall of the mounting groove; then, one side of the packaging cover plate 103 of the OLED module 1 is placed in the mounting groove of the bracket 2, and the side of the OLED module 1 squeezes the second buffer pad 6, and the substrate 101 bonded with the first buffer pad 5 extends out of the mounting groove; then, the fixing member 4 is placed on the bracket 2, and the horizontal limiting portion 41 of the fixing member 4 is in contact with the side of the OLED module 1 and the bracket 2, and the vertical limiting portion 42 presses down on the first buffer pad 5 from above; finally, the fixing member 4 is fixed to the bracket 2 by locking, clamping or riveting.
[0040] It should be noted that, when preparing the bracket 2 , the second buffer pad 6 can be directly fixed on a single inner groove wall of the installation groove to save assembly time.
[0041] In a preferred embodiment, a circle of elastic gasket 7 is provided in the mounting groove.
[0042] For details, please refer to Figure 4 , Figure 4 exist Figure 2 An elastic gasket 7 is additionally provided on the basis of the assembly structure of the first OLED module shown, and the movement of the OLED module 1 is limited by the resilience of the elastic gasket 7, thereby further preventing the OLED module 1 from being displaced in the horizontal direction; the elastic gasket 7 is a rubber gasket.
[0043] Furthermore, the diameter of the elastic gasket 7 is greater than or equal to half the height of the OLED module 1 , and less than or equal to the height of the OLED module 1 .
[0044] Specifically, the diameter of the elastic gasket 7 should not be too large or too small. If it is too small, it may not provide a good limiting protection effect. If it is too large, it may affect the limiting effect of the vertical limiting portion 42 of the fixing member 4. Therefore, in this embodiment, the diameter of the elastic gasket 7 is required to be not less than half of the height of the OLED module 1 and not more than the height of the OLED module 1. For example, it can be 1 / 2, 2 / 3, 3 / 4 of the height of the OLED module 1. For example, if the height of the OLED module 1 is 2 mm, the diameter of the elastic gasket 7 can be 1 mm, 1.3 mm, 1.5 mm, 1.7 mm, 1.9 mm, 2 mm, etc.
[0045] Furthermore, a circle of clamping grooves is provided on the inner groove wall of the installation groove; a part of the elastic gasket 7 is located in the clamping groove, and the other part is located outside the clamping groove.
[0046] Specifically, in order to prevent the elastic gasket 7 from being displaced during the assembly process and affecting the assembly, the elastic gasket 7 needs to be fixed, which can be achieved by clamping, that is, a circle of clamping grooves is opened on the inner groove wall of the installation groove, so that the elastic gasket 7 can be clamped in the circle of clamping grooves. The clamping groove can be an arc shape that matches the shape of the elastic gasket 7. The depth of the clamping groove should not be too large or too small. If it is too small, the limiting effect on the elastic gasket 7 will be too weak. If it is too large, the part of the elastic gasket 7 extending outside the clamping groove will be too small, and it will not have a good limiting protection effect on the OLED module 1. Preferably, the depth of the clamping groove is half of the diameter of the elastic gasket 7, that is, half of the elastic gasket 7 is located in the clamping groove and the other half is located outside the clamping groove. It can ensure that the elastic gasket 7 does not shift and can also ensure that it can have a good limiting protection effect on the OLED module 1.
[0047] Furthermore, the elastic gasket 7 is fixed to the slot by means of fixing glue.
[0048] Specifically, the elastic gasket 7 can be bonded into the slot by fixing glue to further position the elastic gasket 7 .
[0049] Figure 4The assembly method of the third OLED module assembly structure shown is: first, place or glue the elastic gasket 7 in the card slot; then, place one side of the packaging cover plate 103 of the OLED module 1 into the installation groove of the bracket 2, and be located in the space formed by the elastic gasket 7, the side of the OLED module 1 squeezes the elastic gasket 7, and the rebound force of the elastic gasket 7 limits the movement of the OLED module 1; then, place the fixing member 4 on the bracket 2, and make the horizontal limiting portion 41 of the fixing member 4 abut against the side of the OLED module 1 and the bracket 2, and the vertical limiting portion 42 presses down the first buffer pad 5 from above it; finally, fix the fixing member 4 on the bracket 2 by locking, clamping or riveting.
[0050] In a preferred embodiment, the horizontal limiting portion 41 of the fixing member 4 is a rivet post fixedly connected to the bracket 2 . When the OLED module 1 is placed on the bracket 2 , a rivet head is formed by riveting the rivet post, and the rivet head is the vertical limiting portion 42 of the fixing member 4 .
[0051] For details, please refer to Figure 5 and Figure 6 In this embodiment, the bracket 2 is a planar structure, that is, the mounting side does not have a mounting groove. The bracket 2 of this structure can be used to mount OLED modules 1 of regular shapes and irregular shapes.
[0052] Specifically, in this embodiment, the horizontal limiter 41 is a rivet column, and the horizontal limiter 41 and the bracket 2 are an integrally formed structure, specifically obtained by thermoplastic molding, and the horizontal limiter 41 is cylindrical. In order to ensure stable fixation, the number of the horizontal limiters 41 is at least two. Exemplarily, the number of the horizontal limiters 41 is two, and for a rectangular OLED module 1, the two horizontal limiters 41 should be located at the diagonal positions on the two opposite sides of the OLED module 1; in another example, the number of the horizontal limiters 41 is four, and for a rectangular OLED module 1, the four horizontal limiters 41 are respectively located on the four sides of the OLED module 1, and for a circular OLED module, the four horizontal limiters 41 are evenly distributed on the same circumference.
[0053] Specifically, in the present embodiment, the vertical limiting portion 42 is a rivet head, and the vertical limiting portion 42 is formed during the assembly process, specifically, after the OLED module 1 is placed on the bracket 2, the vertical limiting portion 42 is formed by hot riveting the top end of the horizontal limiting portion 41. The vertical limiting portion 42 after thermoforming can press down and fix the non-luminous area of the substrate 101 of the OLED module 1.
[0054] Furthermore, an arc groove is provided on the side of the OLED module 1; when the OLED module 1 is placed on the bracket 2, the horizontal limit portion 41 (rivet column) of the fixing member 4 is located in the arc groove and is close to the bottom of the arc groove.
[0055] Specifically, arc grooves are formed by laser cutting at positions corresponding to the horizontal limit parts 41 on the side of the OLED module 1. During assembly, each horizontal limit part 41 will be in close contact with the bottom of the arc groove corresponding to its position to achieve horizontal limit fixation of the OLED module 1. In addition, by providing arc grooves on the OLED module 1 to cooperate with each horizontal limit part 41, the vertical limit part 42 formed by hot riveting can have a larger crimping area to be crimped to the non-luminous area of the substrate 101, thereby avoiding the insecure crimping due to the small crimping area of the vertical limit part 42, which affects the fixing effect of the OLED module 1 and the bracket 2.
[0056] Figure 5 The assembly method of the fourth OLED module assembly structure shown is: first, place one side of the packaging cover plate 103 of the OLED module 1 on the bracket 2, and locate it in the space surrounded by each horizontal limiting part 41, and each arc groove on the OLED module 1 corresponds to each horizontal limiting part 41 one by one; then, heat-rivet the top end of each horizontal limiting part 41 in turn to form a vertical limiting part 42, and the vertical limiting part 42 is pressed on the non-luminous area of the substrate 101 of the OLED module 1.
[0057] For further information, please refer to Figure 7 In order to enhance the protection of the OLED module 1, the fifth OLED module assembly structure shown in FIG. 1 may further include a plurality of additional components such as: Figure 2 The first buffer pad 5 in the assembly structure of the OLED module is shown. The first buffer pad 5 is located between the vertical limiting portion 42 and the non-luminous area of the substrate 101 .
[0058] For further information, please refer to Figure 7 The fifth OLED module assembly structure shown in FIG. 1 can also be provided with a plurality of additional components on the inner wall of the arc groove to enhance stability.

The OLED module 1 is limited in a dual horizontal direction by the mounting groove and the horizontal limiting portion 41, and the OLED module 1 is limited in a vertical direction by each vertical limiting portion 42 (rivet head).
[0060] For further information, please refer to Fig. 9The seventh OLED module assembly structure shown in FIG. 1 can also be installed in order to increase stability. Figure 8 The sixth OLED module assembly structure shown in FIG. Figure 3 The second buffer pad 6 in the assembly structure of the OLED module shown in the figure, or an additional Figure 4 The elastic gasket 7 in the assembly structure of the OLED module is shown.
