Abstract

The invention provides a display module and a display device. The display module comprises a cover plate, a light-emitting assembly, a shell and a first glue part. A first groove is formed in the surface, facing the cover plate, of the shell, and a light-emitting assembly is arranged in the first groove. In the direction perpendicular to the plane where the display module is located, the portion, not overlapped with the first groove, of the shell is a side wall, a supporting leg is arranged on the side, close to the cover plate, of the side wall, and the orthographic projection of the supporting leg is located on the side, close to the first groove, of the outer edge of the orthographic projection of the side wall. Second grooves are formed in the surfaces, close to the cover plate, of the side walls, and the orthographic projection of the supporting legs and the orthographic projection of the second grooves are at least partially overlapped in the direction away from the orthographic projection of the first grooves. Part of the first glue part is located in the second groove. According to the application, the second groove is arranged to accommodate the adhesive, so that the influence that the adhesive coating area is occupied due to the arrangement of the supporting legs can be counteracted. In addition, the orthographic projection of the supporting leg is overlapped with the orthographic projection of the second groove, so that the phenomenon of glue overflow is further weakened.

Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display module and a display device. Background Art

[0002] In the existing design, the backlight module usually includes a shell structure with a light-emitting component embedded therein, and the support structure included in the shell structure contacts the cover plate to play a supporting role. However, the support structure is usually arranged on the surface of the side wall of the shell structure away from the light-emitting component. This design easily leads to a larger overall size of the shell structure, which is not conducive to the realization of a small-volume backlight module.

[0003] In order to solve the above problem, the prior art chooses to set the support structure on the side of the side wall of the shell structure close to the cover plate. However, usually, adhesive needs to be filled between the side wall of the shell structure and the cover plate. The above setting method of setting the support structure on the side of the side wall close to the cover plate is easy to cause the adhesive to overflow, affecting the setting effect of the light-emitting component and the appearance effect of the backlight module. Summary of the invention

[0004] In view of this, the present application provides a display module and a display device.

[0005] In a first aspect, the present application provides a display module, including a cover plate, a light-emitting component, a housing and a first adhesive portion. The housing is located on one side of the cover plate, and a first groove is provided on the surface of the housing facing the cover plate, in which a light-emitting component is provided. Along a direction perpendicular to the plane where the display module is located, the portion of the housing that does not overlap with the first groove is a side wall, and a supporting foot is provided on the side of the side wall close to the cover plate, and the orthographic projection of the supporting foot is located on the side of the outer edge of the orthographic projection of the side wall close to the first groove. A second groove is provided on the surface of the side wall close to the cover plate, and along a direction away from the orthographic projection of the first groove, the orthographic projection of the supporting foot at least partially overlaps with the orthographic projection of the second groove. Part of the first adhesive portion is located in the second groove.

[0006] In a second aspect, the present application provides a display device, comprising the display module provided in the first aspect.

[0007] The present application provides a second groove to accommodate the adhesive, which helps to offset the impact of the glue application area being squeezed out due to the support foot. In addition, the area on the upper surface of the side wall corresponding to the support foot has a higher risk of glue overflow. By providing the orthographic projection of the support foot and the orthographic projection of the second groove to at least partially overlap in the extension direction perpendicular to the side wall, it helps to give full play to the role of the second groove in accommodating glue overflow, which helps to reduce the glue overflow phenomenon in a targeted manner.

DETAILED DESCRIPTION

[0010] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0011] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0012] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0013] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0014] It is obvious to those skilled in the art that various modifications and changes can be made in this application without departing from the spirit or scope of this application. Therefore, this application is intended to cover modifications and changes of this application that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of this application can be combined with each other without contradiction.

[0015] Figure 1 It is a schematic diagram of a partial structure of a display module related to the present application.

[0016] like Figure 1 As shown, the existing display module generally includes a housing structure 01', and the housing structure 01' is often provided with a groove, and the groove is used to place the light-emitting component (the above groove and the light-emitting component are not Figure 1 ). A support structure 02' is provided on the side wall 01a' of the shell structure 01' for supporting the cover plate 03'. The support structure 02' is usually provided on the outer surface of the side wall 01a'. This arrangement easily leads to a larger size of the shell structure 01' in the horizontal direction (the direction parallel to the plane where the cover plate 03' is located).

[0017] Figure 2 It is a schematic diagram of a partial structure of a display module related to the present application.

[0018] To solve the above problem of large size, such as Figure 2 As shown, in the prior art, the support structure 02' is usually arranged on the side of the side wall 01a' close to the cover plate 03', so as to Avoid the support structure 02' from increasing the size of the shell structure 02' in the lateral direction. It should be noted that adhesive is usually filled between the cover plate 03' and the side wall 01a' to achieve the adhesion of the cover plate 03' to the shell structure 01'. The filling process of the above adhesive usually includes: applying adhesive on the surface of the side wall 01a' close to the cover plate 03' (which can be called the upper surface), and then making the cover plate 03' contact with the support structure 02' on the upper surface. Since the support structure 02' is provided on the upper surface, it is equivalent to that the support structure 02' occupies part of the area of ​​the upper surface, which reduces the coating area of ​​the adhesive on the upper surface. In the process of applying the adhesive, due to the existence of the support structure 02', part of the adhesive is easy to overflow under the crowding of the support structure 02', break away from the upper surface, and overflow to the outer surface of the side wall 01a' (the surface of the side wall 01a' away from the light-emitting component) and / or the inner surface (the surface of the side wall 01a' close to the light-emitting component). Considering the adhesiveness and color characteristics of the adhesive itself (usually black), the overflowed adhesive is likely to affect the position setting of the light-emitting component in the groove and the appearance of the shell structure 01 ′.

[0019] Figure 3 A schematic diagram of a partial structure of a display module provided in this application, Figure 4 A schematic diagram of a partial structure of a display module provided in the present application from another viewing angle, Figure 5 for Figure 3 The projection diagram of the partial structure of the display module shown in FIG. is for the convenience of understanding. Figure 5 Only the projection parts corresponding to the first groove, the second groove, the supporting foot, the side wall and other structures are shown.

[0020] In response to the above problems, Figure 3 As shown, the present application provides a display module 01, including a cover plate 1 and a light emitting assembly 2, the light emitting assembly 2 can be located on one side of the cover plate 1, and during the operation of the display module 01, the light emitting assembly 2 can be used to provide the backlight required for display. The light emitting assembly 2 can include a plurality of light emitting devices, and the light emitting device can include a mini light emitting diode (mini-LED).

[0021] Combination Figure 3 and Figure 4 The display module 01 further includes a housing 3, which is located on one side of the cover plate 1. The surface of the housing 3 facing the cover plate 1 is provided with a first groove 31 (reference Figure 3 ), a light emitting component 2 is disposed in the first groove 31.

[0022] In a direction perpendicular to the plane where the display module 01 is located, the portion of the housing 3 that does not overlap with the first groove 31 is a side wall 32, and the side wall 32 can at least partially surround the light-emitting component 2. A support foot 33 is provided on the side of the side wall 32 close to the cover plate 1, and the support foot 33 can contact the cover plate 1.

[0023] Combination Figure 3 , Figure 4 and Figure 5 , the orthographic projection of the support foot 33 may correspond to the first orthographic projection 330, the orthographic projection of the side wall 32 may correspond to the second orthographic projection 320, and the orthographic projection of the first groove 31 may correspond to the third orthographic projection 310. The first orthographic projection 330 may overlap with the second orthographic projection 320, and the first orthographic projection 330 may be located at the outer edge 320a of the second orthographic projection 320 (refer to Figure 5 The portion marked by the dotted line in FIG. 3 is close to one side of the third orthographic projection 310.

[0024] A second groove 34 is provided on the surface of the side wall 32 close to the cover plate 1, and the second groove 34 can be used to accommodate the adhesive filled between the cover plate 1 and the shell 3. Figure 5 As shown, along the direction X away from the orthographic projection 310 of the first groove 31 , the orthographic projection 330 of the support foot 33 at least partially overlaps with the fourth orthographic projection 340 (the orthographic projection of the second groove 34 ).

[0025] The display module 01 further includes a first adhesive portion 4, and a portion of the first adhesive portion 4 is located in the second groove 34. In addition, at least a portion of the first adhesive portion 4 may be located between the housing 3 and the cover plate 1, specifically, the first adhesive portion 4 may be located between the side wall 32 and the cover plate 1, and along a direction perpendicular to the plane where the display module 01 is located, the first adhesive portion 4 may overlap with both the cover plate 1 and the side wall 32.

[0026] Since the support foot 33 is located on the side of the shell 3 facing the cover plate 1, the support foot 33 occupies a part of the surface of the shell 3 facing the cover plate 1 (which can be called the upper surface). Therefore, in the process of applying the adhesive to form the first adhesive portion 4, glue overflow is likely to occur on the upper surface. In order to reduce the risk of glue overflow, in the embodiment of the present application, a second groove 34 is provided to accommodate the adhesive to offset the effect of the glue coating area being occupied due to the provision of the support foot 33. In addition, the risk of glue overflow in the area corresponding to the support foot 33 on the upper surface is relatively high. By setting the first orthographic projection 330 and the fourth orthographic projection 340 to at least partially overlap, it is helpful to give full play to the role of the second groove 34 in accommodating glue overflow, which is conducive to targeted reduction of glue overflow.

[0027] Figure 6 A schematic diagram of a partial structure of a display module provided in the present application.

[0028] In one embodiment of the present application, Figure 6 As shown, the side of the support foot 33 close to the first groove 31 is flush with the side of the side wall 32 close to the first groove 31. In this arrangement, during the application of the adhesive, the adhesive applied to the area of ​​the upper surface corresponding to the support foot 33 is more likely to overflow in a direction away from the first groove 31 than in a direction close to the first groove 31.

[0029] At least a portion of the second groove 34 is located on a side of the supporting foot 33 away from the first groove 31 .

[0030] In the embodiment of the present application, at least a portion of the second groove 34 is disposed on a side of the support foot 33 away from the first groove 31. Under this arrangement, the second groove 34 can accommodate the adhesive that overflows to the outside of the side wall 32, which is beneficial to reduce the adhesive that overflows to the outer surface of the side wall 32, thereby improving the poor visual appearance of the display module 01 caused by the overflow of the adhesive.

[0031] Figure 7 A schematic diagram of a partial structure of a display module provided in the present application.

[0032] In one embodiment of the present application, Figure 7 As shown, the side of the second groove 34 away from the supporting foot 33 is flush with the surface of the side wall 32 away from the first groove 31 .

[0033] In the embodiment of the present application, one side of the second groove 34 is flush with the outer surface of the side wall 32, which means that most of the area on the upper surface can be used to set the second groove 34. For example, the second groove 34 can be set on the portion of the upper surface between the support foot 33 and the outer edge of the side wall 32. This arrangement can increase the width of the second groove 34 as much as possible, which helps to improve the second groove 34's ability to accommodate adhesive.

[0034] In addition, when one side of the second groove 34 is flush with the outer edge of the side wall 32 , in order to prevent the adhesive in the second groove 34 from continuing to overflow to the outer surface of the side wall 32 , the depth h of the second groove 34 can be increased, thereby increasing the corresponding volume of the second groove 34 .

[0035] Figure 8 A schematic diagram of a partial structure of a display module provided in this application, Fig. 9 for Figure 8 The schematic cross-sectional view of a partial structure of the display module is shown along the section line AA′.

[0036] In one embodiment of the present application, Figure 8 and Fig. 9 , the first adhesive part 4 includes a first part 41 and a second part 42. In a direction perpendicular to the plane where the display module is located, the first part 41 overlaps with the second groove 34, and the second part 42 does not overlap with the second groove 34. It should be noted that in order to bond the cover plate 1 and the housing 3, the first adhesive part 4 can contact both the cover plate 1 and the housing 3. Among them, part of the first part 41 can be located in the second groove 34, and the height of the first part 41 can be greater than the height of the second part 42.

[0037] The width w1 of the first part 41 is smaller than the width w2 of the second part 42. Due to the existence of the support foot 33, the width of the second groove 34 can be smaller than the maximum width of the side wall 32, so w1 can be smaller than w2. At this time, considering that the height of the first part 41 can be greater than the height of the second part 42, if w1<w2 at the same length, it is helpful to achieve that the volume of the first part 41 is equal to the volume of the second part 42, and it is helpful to achieve that the amount of adhesive corresponding to the first part 41 is equal to the amount of adhesive corresponding to the second part 42. The significance of this effect is that in the coating process of the adhesive, due to process limitations, the amount of adhesive coated on the corresponding area on the upper surface is easy to be equal to the amount of adhesive coated on the non-corresponding area on the upper surface. The corresponding area can refer to the area on the upper surface corresponding to the support foot 33, and the non-corresponding area can refer to the area on the upper surface that does not correspond to the support foot 33. For the convenience of understanding, the lengths corresponding to the two areas in the extension direction of the side wall 32 can be regarded as the same. Therefore, to avoid glue overflow, it is necessary to ensure that the second groove 34 can accommodate the adhesive overflowed by the supporting foot 33, that is, it is necessary to ensure that when the length is the same and w1<w2, the volume of the first part 41 is equal to the volume of the second part 42.

[0038] Among them, combined Figure 8 and Fig. 9 , the height of the first portion 41 is h1+h2, the height of the second portion 42 is h1, and the depth of the second groove 34 is h2=(w2 / w1-1) h1.

[0039] In the process of filling the adhesive, the amount of adhesive filled per unit length in the corresponding area can be regarded as A, and the amount of adhesive filled per unit length in the non-corresponding area can be regarded as B. Due to the limitation of the adhesive injection process, A=B is likely to occur.

[0040] Taking into account that the width of the above-mentioned corresponding area (which can be regarded as the width w1 of the above-mentioned first part 41) is smaller than the width of the above-mentioned non-corresponding area (which can be regarded as the width w2 of the above-mentioned second part 42), therefore, without considering the additional volume V1 brought by the second groove 34 (the volume can refer to the volume used to accommodate the adhesive), the volume V2 corresponding to the above-mentioned non-corresponding area within a unit length range can be greater than the volume V3 corresponding to the above-mentioned corresponding area within a unit length range.

[0041] When the non-corresponding area can just accommodate adhesive with an adhesive amount of B within a unit length range, in order to prevent the corresponding area from overflowing, V2=V1+V3 needs to be achieved. In which, when the second groove 34 is filled with adhesive, V1+V3=(h1+h2) w1 ΔL; V2=h1 w2 ΔL; ΔL here may refer to the unit length along the extension direction of the side wall 32. Substituting the above equation into the equation, it can be obtained that the depth h2 of the second groove 34 is (w2 / w1-1) h1.

[0042] Fig.10 This is a schematic diagram of some corresponding steps in preparing some structures in the display module provided in the present application.

[0043] In addition, if Fig.10 As shown, the preparation process of the display module 01 may include: coating adhesive on the surface of the outer shell 3 facing the cover plate 1 (which may be referred to as the upper surface), and then attaching the cover plate 1 to one side of the upper surface of the outer shell 3. Before attaching the cover plate 1, the height of the adhesive coated in the corresponding area (which may be referred to as the height before the pressing plate) may be h3, and the width of the adhesive (which may be referred to as the width before the pressing plate) may be w3. After attaching the cover plate 1, it is necessary to ensure that the portion of the cover plate 1 that overlaps with the second groove 34 can contact the adhesive, and the height before the pressing plate must satisfy h3>h1+h2. Considering that h2=(w2 / w1-1) h1, after substituting this condition, it can be obtained that the width w1 of the second groove 34 is greater than the front width w3 of the pressure plate.

[0044] Fig.11 The following is a schematic diagram of some steps corresponding to the preparation of a partial structure of a display module provided by the present application. Fig.12 This is a schematic top view of a partial structure of a display module provided in this application. It should be noted that: Fig.11 The steps for assembling the fixing frame and the housing are shown in the figure and do not represent Fig.11 The structure shown in the figure is the structure after the display module is prepared.

[0045] In one embodiment of the present application, Fig.11 As shown, the display module 01 also includes a fixing frame 5, part of which can be located on the side of the light-emitting component 2 close to the cover plate 1. The fixing frame 5 can be used to fix the light-emitting component 2 in the first groove 31 to reduce the degree of up and down deviation of the light-emitting component 2 in the first groove 31.

[0046] In addition, the fixing frame 5 may be made of at least one of metal aluminum and metal magnesium.

[0047] The fixing frame 5 is provided with an opening 51 penetrating the fixing frame 5 , and the opening 51 exposes part of the light emitting component 2 . During the operation of the display module 01 , the light generated by the light emitting component 2 can pass through the opening 51 and propagate along the opening direction of the first groove 31 .

[0048] Among them, combined Fig.11 and Fig.12 , the orthographic projection of the housing 3 covers the orthographic projection of the fixing frame 5.

[0049] In the embodiment of the present application, the orthographic projection of the housing 3 covers the orthographic projection of the fixing frame 5 . Further, at least a portion of the fixing frame 5 may overlap with the first groove 31 , which means that the fixing frame 5 may not protrude from the outer edge of the housing 3 .

[0050] Fig.13 A schematic diagram of a partial structure of a display module provided in the present application.

[0051] In one embodiment of the present application, Fig.13 As shown, the fixing frame 5 includes an overlap portion 52, and the overlap portion 52 at least partially overlaps the side wall 32 along a direction perpendicular to the plane where the display module 01 is located. The overlap portion 52 can abut against the surface of the side wall 32 close to the cover plate 1, and the side wall 32 can provide a supporting force for the overlap portion 52, preventing the fixing frame 5 from further deviating toward the bottom of the first groove 31, thereby enhancing the structural stability.

[0052] In addition, the overlapping portion 52 is located between the surface of the side wall 32 close to the cover plate 1 and the first adhesive portion 4 .

[0053] In the embodiment of the present application, the overlapping portion 52 is arranged between the upper surface of the side wall 32 and the first adhesive portion 4, which helps to ensure that the upper surface of the side wall 32 and the first adhesive portion 4 are in contact with the overlapping portion 52, helps to limit the displacement of the overlapping portion 52 in the vertical direction (perpendicular to the plane where the display module 01 is located), and helps to enhance the fixing effect of the fixing frame 5 on the light-emitting component 2.

[0054] Fig.14 A schematic diagram of a partial structure of a display module provided in this application, Fig.15 for Fig.14 The schematic cross-sectional view of a partial structure of the display module is shown along the section line BB'.

[0055] In one embodiment of the present application, Fig.14 As shown, the surface of the side wall 32 close to the cover plate 1 includes a first area 32a and a second area 32b. The second area 32b partially surrounds the first area 32a. The first area 32a may be adjacent to the second area 32b and the first groove 31.

[0056] The first region 32a is provided with a third groove 35, and at least part of the overlap portion 52 is located in the third groove 35. When the fixing frame 5 is combined with the housing 3, the third groove 35 is provided to enhance the alignment effect between the fixing frame 5 and the housing 3, and improve the fixing effect of the fixing frame 5 on the light emitting component 2.

[0057] Optionally, the overlapping portion 52 may abut against the bottom of the third groove 35 .

[0058] Among them, combined Fig.14 and Fig.15 , along the direction perpendicular to the plane where the display module 01 is located, the distance between the surface of the overlapping portion 52 close to the cover plate 1 and the cover plate 1 is H1, and the distance between the second area 32b and the cover plate 1 is H2, H1>H2. That is, relative to the portion of the upper surface of the side wall 32 corresponding to the second area 32b, the surface of the overlapping portion 52 close to the cover plate 1 is farther away from the cover plate 1.

[0059] In the embodiment of the present application, considering that the overlapping portion 52 can contact the first glue portion 4, when H1>H2, it means that part of the first glue portion 4 may be located in the third groove 35. At this time, the third groove 35 can accommodate the adhesive, which helps to further reduce the above-mentioned glue overflow phenomenon.

[0060] Fig.16 for Fig.14 Another cross-sectional view of a partial structure of the display module along the section line BB' is shown.

[0061] In one embodiment of the present application, Fig.14 and Fig.16 , adhesive m is provided between the bottom of the third groove 35 and the overlapping portion 52.

[0062] In the embodiment of the present application, the adhesive m can contact both the bottom of the third groove 35 and the overlap portion 52, and the adhesive m can fix the overlap portion 52, reducing the relative displacement between the overlap portion 52 and the bottom of the third groove 35. In particular, the adhesive m can be provided before the fixing frame 5 is combined with the housing 3, and when the fixing frame 5 is combined with the housing 3, the adhesive m can adhere the overlap portion 52 to the third groove 35, reducing the positional displacement of the fixing frame 5 when it is attached to the housing 3.

[0063] Fig.17 This is a projection diagram of a partial structure of a display module provided in this application. For ease of understanding, Fig.17 Only the positional relationship between the orthographic projection of the third groove and the orthographic projection of the overlapping portion is shown.

[0064] In one embodiment of the present application, Fig.14 and Fig.17 , the orthographic projection 350 of the third groove 35 covers the orthographic projection 520 of the overlapping portion 52 .

[0065] In the embodiment of the present application, since the orthographic projection 350 of the third groove 35 covers the orthographic projection 520 of the overlapping portion 52, and considering the above-mentioned H1>H2, the overlapping portion 52 can be completely located in the third groove 35, avoiding the glue overflow caused by the overlapping portion 52 protruding from the third groove 35.

[0066] In one embodiment of the present application, H1-H2=0.1 mm. This configuration helps to control the difficulty of preparing the third groove 35 while maximizing the supporting effect of the overlap portion 52.

[0067] Fig.18 A schematic diagram of a partial structure of a display module provided in this application, Fig.19 for Fig.18 The schematic cross-sectional view of a partial structure of the display module is shown along the section line CC'.

[0068] In one embodiment of the present application, Fig.18 and Fig.19 A slot 321 is provided on the surface of the side wall 32 close to the first groove 31. The slot 321 is further away from the cover plate 1 than the surface of the side wall 32 close to the cover plate 1. In the direction perpendicular to the plane where the display module 01 is located, the distance between the surface of the side wall 32 close to the cover plate 1 and the cover plate 1 is h3, and the minimum distance between the slot 321 and the cover plate 1 is h4, where h4>h3.

[0069] The fixing frame 5 includes a lug 53, at least part of which is located in the slot 321. The lug 53 can abut against the inner wall of the slot 321, and the slot 321 can fix the lug 53 to prevent the position of the lug 53 from being offset.

[0070] Fig. 20 This is a schematic diagram of a partial structure of a display module provided in this application. For ease of understanding, Fig. 20 Displaying some structures in the display module in a split manner does not mean Fig. 20 The positional relationship between the structures shown in the figure corresponds to the structural schematic diagram of the display module after preparation.

[0071] In one embodiment of the present application, Fig. 20 As shown, the display module 01 further includes a liquid crystal layer 6, which is located on a side of the cover plate 1 close to the light emitting component 2.
