[0002] With the continuous progress of the technology in the liquid crystal industry, the large size and ultra-narrow bezel of the LCD (Liquid Crystal Display) screen display have increasingly become the mainstream market demand, and are widely used in display devices such as televisions, smart phones, and tablet computers. While the bezel is getting narrower, in the display module, the display panel is directly exposed. Due to the structural limitations of the overall components, during the corner drop test, it is easy to cause the problem of broken fragments at the corners of the display panel. Even when the display module is integrated into the display device, the same problem of being afraid of falling and being fragile will occur. Therefore, while retaining the narrow bezel, avoiding the fragility of the display panel has become an urgent problem to be solved. Summary of the Utility Model

[0013] The second glue frame and the first glue frame are integrally formed.

[0014] Optionally, the first receiving portion includes a side plate, a second back plate, and a third glue frame. The side plate is disposed on one side edge of the back plate facing the second substrate. The second back plate is connected to one end of the side plate away from the back plate, and the extending direction of the second back plate is away from the cavity and the second back plate is parallel to the back plate. The back plate, the side plate, and the second back plate are integrally formed.

[0015] The third glue frame is disposed on one side of the first glue frame and the second back plate away from the back plate. There is a first gap between the side of the third glue frame facing the cavity and the display panel.

[0034] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the following further details the present utility model in conjunction with specific embodiments and with reference to the accompanying drawings.

[0035] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present utility model should be the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure pertains. The "first", "second" and similar terms used in the present disclosure do not denote any order, quantity or importance, but are only used to distinguish different components. The terms such as "include" or "comprise" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. The terms such as "connect" or "couple" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0036] In order to pursue ultra-narrow borders and ultra-thin thickness, refer to Figure 1 and Figure 2As shown, a new type of display module structure proposed by the applicant, namely the Slat (Super Light and Thin) module, directly uses the upper polarizer 3 as the outer light surface, eliminating the cover glass (CG) and optical adhesive layer (OCA) required in the TLCM assembly process in the related art. Therefore, its thickness and border can be further reduced to improve, reduce costs, and at the same time enhance the product competitiveness. However, in the display module, the color filter substrate 1 (CF glass) and the thin film transistor substrate 2 (Thin Film Transistor glass, TFT glass) are directly exposed and matched with the whole machine components, that is, the border 4. Therefore, there is no protection on the side of the CF glass and the TFT glass. Therefore, during the drop test, it is easy to break the CF glass and the TFT glass. Due to the limitations of the structure, it is difficult to apply effective countermeasures. Even if it is forcibly installed on display devices such as laptops and tablets, if the user accidentally drops it, the same problem is likely to occur, increasing the user's usage experience and purchase cost. Therefore, it restricts the market promotion of the Slat module. Therefore, the purpose of the present utility model is to solve the problem of broken pieces caused by the interference between the CF glass and the TFT glass and the whole machine components while realizing the overall reduction of the thickness and the border.

[0037] To improve the ultra-narrow border and ultra-narrow thickness of the display module while enhancing the overall strength of the display module, thereby improving the yield of the display device, the embodiments of the present application provide a display module and a display device. The following will describe in detail the display module and the display device provided by the embodiments of the present application with reference to the accompanying drawings. Among them, the display module includes but is not limited to LCD (Liquid Crystal Display) display modules, TFT-LCD (Thin Film Transistor Liquid Crystal Display) display modules, etc.

[0038] Refer to Figures 3 to 5 As shown, a display module provided by the present application includes a display panel 5, including a first substrate 51 and a second substrate 52 arranged opposite to each other. Exemplarily, the first substrate 51 can be a color filter substrate (CF glass), and the second substrate 52 can be a thin film transistor substrate (Thin Film Transistor glass, TFT glass).

[0039] The display panel 5 is used to display images. The display panel 5 can be an LCD (Liquid Crystal Display) panel, a TFT-LCD (Thin Film Transistor Liquid Crystal Display) panel, or the like.

[0040] Between the first substrate 51 and the second substrate 52, there are also a liquid crystal layer, pixel electrodes, a common electrode, etc. (not shown in the figure). By applying a voltage to the pixel electrodes, the pixel electrodes are connected to the common electrode through the liquid crystal layer to form a circuit, determining that the liquid crystal layer deflects. By changing the applied voltage, the deflection angle of the liquid crystal molecules in the liquid crystal layer is controlled, thereby adjusting the brightness of the second substrate 52 in the corresponding area, and finally displaying the desired color from the first substrate 51.

[0041] The backplane 6 is disposed on the side of the second substrate 52 away from the first substrate 51. The first receiving portion 7 is disposed on the side edge of the backplane 6 facing the second substrate 52. The first receiving portion 7 and the backplane 6 form a cavity, and the display panel 5 is placed in the cavity. The side of the first receiving portion 7 facing the cavity has a first gap 11 from the display panel 5.

[0042] The backplane 6 is used to support the display module and increase the overall strength of the display module. The backplane 6 and the first receiving portion 7 jointly define a cavity, and the cavity is used to accommodate other components between the display panel 5 and the backplane 6. Optionally, the material of the backplane 6 can be a material with relatively high hardness and light weight, such as aluminum or aluminum alloy. While playing a role in supporting and protecting the display module, it does not increase the overall weight of the display module.

[0043] Through the cavity jointly defined by the first receiving portion 7 and the backplane 6, the display panel 5 is no longer directly exposed. At the same time, the first receiving portion 7 plays a corresponding protective role on the side of the display panel 5. During the process of falling from a height, the direct contact between the display panel 5 and the first receiving portion 7 will also cause structural interference. Especially at the corners, the display panel 5 is also prone to fragmentation. Using the first gap 11 between the first receiving portion 7 and the display panel 5, a buffer space is formed during the falling process. Whether it is the falling test during the production process or integrated into the display device, it can protect the display panel 5 while avoiding the problem of fragmentation of the display panel 5.

[0044] In some embodiments, the display module further includes a first rubber frame 21. The first rubber frame 21 is closely attached to the first receiving portion 7 and disposed on the side facing the cavity. The side of the rubber frame facing the bottom plate is connected to the bottom plate, and the side away from the bottom plate and facing the center of the cavity is connected to the edge of the display panel 5 facing the bottom plate.

[0045] The first rubber frame 21 supports and fixes the display panel 5 located in the cavity jointly defined by the back plate 6 and the first receiving portion 7, ensuring that the position of the display panel 5 remains unchanged, thereby guaranteeing the stability of the display effect. At the same time, the strength of the display panel 5 is increased. During the process of the display panel 5 falling face down, the anti-drop and anti-twist capabilities of the display panel 5 are improved, and the service life of the display panel 5 is extended. Further, during the process of the display panel 5 falling from the side, since the first rubber frame 21 fixes the display panel 5, it plays a buffering role in the contact between the display panel 5 and the first receiving portion 7, preventing the display panel 5 from directly contacting the first receiving portion 7. Cooperating with the first gap 11, it further plays a buffering role, further preventing the display panel 5 from directly contacting the first receiving portion 7, and solving the problem of generating fragments between the display panel 5 and the first receiving portion 7.

[0046] Optionally, the rubber frame can be made of materials such as silicone and two-component glue. The elasticity therein can adapt to the stress and deformation during the use of the display panel 5, and at the same time has high adhesion and durability, improving the service life of the display module.

[0047] In some embodiments, referring to Figure 3 As shown, the first receiving portion 7 includes a side plate 71. The side plate 71 is provided at one side edge of the back plate 6 facing the second substrate 52. The side of the side plate 71 facing the cavity has a first gap 11 with the display panel 5; the side plate 71 and the back plate 6 are integrally formed.

[0048] In this embodiment, only the side plate 71 is used as the first receiving portion 7. The side plate 71 serves as the frame of the display module, improving the overall strength of the display module, reducing the probability of damage to the internal structure of the display module, mainly reducing the probability of damage to the display panel 5. In addition, the thickness of the side plate 71 is small. As the frame of the display module, while protecting the display module, the narrow frame requirement of the display module is realized. The first gap 11 between the side plate 71 and the display panel 5 provides a buffering space during the process of the display module falling from the side, avoiding the interference caused by the direct contact between the display panel 5 and the first receiving portion 7, reducing the probability of the display panel 5 being fragmented, and improving the side strength of the display module and the yield of the display module.

[0049] The side plate 71 and the back plate 6 are integrally formed by stamping, improving the integrity of the back plate 6 and the side plate 71, enhancing the strength of the back plate 6 and the side plate 71, and simplifying the manufacturing process and reducing costs.

[0050] In some embodiments, referring to Figure 4As shown, the first receiving portion 7 includes a side plate 71 and a second glue frame 72. The side plate 71 is disposed on one side edge of the back plate 6 facing the second substrate 52, and the side plate 71 and the back plate 6 are integrally formed. The second glue frame 72 is disposed on one side of the first glue frame 21 and the side plate 71 away from the back plate 6. There is a first gap 11 between the side of the second glue frame 72 facing the cavity and the display panel 5, and the second glue frame 72 and the first glue frame 21 are integrally formed.

[0051] In this embodiment, the side plate 71 and the second glue frame 72 are jointly used as the first receiving portion 7. Among them, the side plate 71 provides a supporting function for the second glue frame 72 by virtue of its strength characteristics. According to the actual required frame width of the display module, the width of the second glue frame 72 can be correspondingly set. Here, the width of the second glue frame 72 refers to the width in the same direction as the extension direction of the display panel 5. It can be understood that by using the side plate 71 and the second glue frame 72 jointly as the first receiving portion 7, the first receiving portion 7 as the frame of the display module is wider than using only the side plate 71 as the frame of the display module.

[0052] Using the side plate 71 and the second glue frame 72 jointly as the frame of the display module also improves the overall strength of the display module and reduces the probability of damage to the internal structure of the display module. In addition, the thickness of the second glue frame 72 can be adjusted according to the required frame thickness. The first gap 11 between the second glue frame 72 and the display panel 5 provides a buffer space during the side fall of the display module, avoiding interference caused by direct contact between the display panel 5 and the second glue frame 72, reducing the probability of the display panel 5 being fragmented, improving the side strength of the display module and the yield of the display module. At the same time, the material of the second glue frame 72 is different from that of the side plate 71, and the second glue frame 72 itself has a certain elasticity. Even if the display module falls from the side and the first gap 11 cannot fully buffer, the elasticity of the second glue frame 72 can also avoid completely rigid contact with the display panel 5, more effectively protecting the display module.

[0053] The side plate 71 and the back plate 6 are integrally formed by stamping, improving the integrity of the back plate 6 and the side plate 71, enhancing the strength of the back plate 6 and the side plate 71, and simplifying the manufacturing process and reducing costs. The second glue frame 72 and the first glue frame 21 are integrally formed, similarly simplifying the manufacturing process and reducing costs, while enhancing the overall strength of the first glue frame 21 and the second glue frame 72. While the first glue frame 21 plays a role in carrying and fixing the display panel 5, the second glue frame 72 satisfies the protection of the side of the display panel 5.

[0054] In some embodiments, refer to Figure 5 and Figure 10As shown in the figure, the first receiving portion 7 includes a side plate 71, a second back plate 73, and a third rubber frame 74. The side plate 71 is disposed on one side edge of the back plate facing the second substrate 52. The second back plate 73 is connected to one end of the side plate 71 away from the back plate, and the extending direction of the second back plate 73 is away from the cavity and the second back plate 73 is parallel to the back plate. The back plate, the side plate 71, and the second back plate 73 are integrally formed. The third rubber frame 74 is disposed on one side of the first rubber frame 21 and the second back plate 73 away from the back plate 6. There is a first gap 11 between the side of the third rubber frame 74 facing the cavity and the display panel 5. The third rubber frame 74 and the first rubber frame 21 are integrally formed.

[0055] In this embodiment, the side plate 71, the second back plate 73, and the third rubber frame 74 are jointly used as the first receiving portion 7. Among them, the side plate 71 and the second back plate 73 provide a supporting effect for the third rubber frame 74 by virtue of their strength characteristics. According to the frame width actually required by the display module, when a wider frame is required, the widths of the second back plate 73 and the third rubber frame 74 are set. Here, the widths of the second back plate 73 and the third rubber frame 74 refer to the widths in the same direction as the extending direction of the display panel 5. It can be understood that by jointly using the side plate 71, the second back plate 73, and the third rubber frame 74 as the first receiving portion 7, the first receiving portion 7, as the frame of the display module, is wider than using the side plate 71 and the second rubber frame 72 as the frame of the display module.

[0056] Compared with the above embodiment, the width of the third rubber frame 74 is wider than the width of the second rubber frame 72. The second back plate 73 provides support for the third rubber frame 74. The larger the width of the third rubber frame 74, the better the protection of the display panel 5, and the more effective protection of the display module.

[0057] The side plate 71, the back plate, and the second back plate 73 are integrally formed by stamping, which improves the integrity of the back plate and the side plate 71, improves the strength of the back plate 6 and the side plate 71, simplifies the manufacturing process, and reduces costs. The third rubber frame 74 and the first rubber frame 21 are integrally formed, which also simplifies the manufacturing process, reduces costs, and at the same time improves the overall strength of the first rubber frame 21 and the second rubber frame 72. While the first rubber frame 21 realizes the bearing and fixing functions for the display panel 5, the second rubber frame 72 satisfies the protection of the side of the display panel 5.

[0058] In some embodiments, a first polarizer 8 is provided on the side of the first substrate 51 away from the second substrate 52, a second polarizer 9 is provided on the side of the second substrate 52 away from the first substrate 51, and one side edge of the first polarizer 8 facing the first substrate 51 is connected to the side of the first receiving portion 7 away from the back plate 6.

[0059] In this embodiment, the first polarizer 8 is directly used as the upper polarizer for the outer light surface of the display module, eliminating the cover plate and the optical adhesive layer, reducing the thickness of the display module and improving it, and reducing the costs of the cover plate and the optical adhesive layer.

[0060] Using the side plate 71 as the first receiving portion 7, in the display module, while protecting the display panel 5, the side plate 71 bears the first polarizer 8, preventing the display panel 5 from being exposed.

[0061] Using the side plate 71 and the second rubber frame 72 as the first receiving portion 7, while the first rubber frame 21 bears and fixes the display panel 5, the second rubber frame 72 protects the side of the display panel 5 and bears the first polarizer 8. The first rubber frame 21 and the second rubber frame 72 are integrally formed, with higher stability, which is beneficial to protecting the display panel 5 and realizing the bearing of the first polarizer 8 and the display panel 5 at the same time.

[0062] Using the side plate 71, the second back plate 73, and the third rubber frame 74 as the first receiving portion 7, while the first rubber frame 21 bears and fixes the display panel 5, the third rubber frame 74 protects the side of the display panel 5 and bears the first polarizer 8. The first rubber frame 21 and the third rubber frame 74 are integrally formed, with higher stability, which is beneficial to protecting the display panel 5 and realizing the bearing of the first polarizer 8 and the display panel 5 at the same time.

[0063] It can be understood that the second polarizer 9 is used to convert the light beam generated by the backlight into polarized light, and the first polarizer 8 is used to analyze the polarized light after the liquid crystal in the display panel 5 is electro-modulated, generating light and dark contrast, thereby generating a display image.

[0064] In some embodiments, referring to Figure 7 as shown, the display module at least includes a first side 31, a second side 32, a third side 33, and a fourth side 34. On the first side 31, the second side 32, and the third side 33, the orthographic projection of the display panel 5 on the back plate 6 is within the orthographic projection range of the first polarizer 8 on the back plate 6, and the orthographic projection of the second substrate 52 on the back plate 6 is within the orthographic projection range of the first substrate 51 on the back plate 6. Optionally, the false surface shape of the display module is rectangular, the first side 31, the second side 32, and the third side 33 are respectively the left side, the right side, and the upper side of the display module, and the fourth side 34 is the lower side of the display module. Correspondingly, the display module can also be other shapes, such as a hexagon, which is not specifically limited herein.

[0065] Referring to Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8As shown, compared with the display panel 5, the first polarizer 8 has a protruding part in the horizontal direction. The protruding part facilitates the connection of the first polarizer 8 by the first receiving part 7 and supports the first polarizer 8. The recessed part of the display panel 5 relative to the first polarizer 8 facilitates the setting of the first gap 11 on the first side 31, the second side 32, and the third side 33. The first substrate 51 and the second substrate 52 are flush, achieving stable light emission of the entire display module. Through the above settings on the first side 31, the second side 32, and the third side 33, other settings can be reduced to achieve a narrow border.

[0066] In some embodiments, referring to Figure 6 、 Figure 7 and Figure 9 as shown, on the fourth side 34, the orthographic projection of the first polarizer 8 on the backplane 6 is within the orthographic projection range of the display panel 5 on the backplane 6, and the orthographic projection of the first substrate 51 on the backplane 6 is within the orthographic projection range of the second substrate 52 on the backplane 6.

[0067] In this embodiment, the fourth side 34 serves as the wiring side of the display module. From the cross-sectional view in the figure, the coverage range of the first polarizer 8 is smaller than that of the display panel 5. The excess part of the display panel 5 is covered by other materials as a border. The length of the display panel 5 on the fourth side 34 is greater than that of the first polarizer 8, enabling effective display using the first polarizer 8 on the fourth side 34 and avoiding the situation where the picture cannot be displayed. And the length of the second substrate 52 on the fourth side is greater than that of the first substrate 51. The excess part does not have a corresponding liquid crystal layer, but a corresponding fan-shaped wiring area is set to arrange the circuit between the first substrate 51 and the second substrate 52.

[0068] It should be noted that on the fourth side 34, there is also a corresponding first gap 11 between the display panel 5 and the first receiving part 7.

[0069] In some embodiments, it further includes a backlight module 10 disposed in the cavity. The backlight module 10 is located between the second polarizer 9 and the backplane 6. There is a second gap 12 between the side of the first rubber frame 21 facing the center of the cavity and the backlight module 10.

[0070] Optionally, the backlight module 10 may include a reflection layer 101, a lamp board 102, a light guide plate 103, a first diffusion sheet 104, a first prism layer 105, a second prism layer 106, and a second diffusion sheet 107 that are stacked in sequence. The lamp board 102 is used for emitting light. The emitted light is reflected by the reflection layer 101 and uniformly irradiates the display panel 5 through the light guide plate 103, the first diffusion sheet 104, the first prism layer 105, the second prism layer 106, and the second diffusion sheet 107, improving the light emission efficiency of the display panel 5.

[0071] The materials of different layers in the display module are different. Exemplarily, the light guide plate 103 can be made of polymethyl methacrylate (PMMA) or polycarbonate (PC) materials. As the environmental temperature of the display module varies, the different layer materials will expand and contract thermally, and the second gap 12 provides space for the thermal expansion of the film layer. In addition, similar to the display panel 5, the second gap 12 prevents the backlight module 10 from directly contacting the first rubber frame 21. During the decline test of the display module and when the user accidentally drops it, the second gap 12 also provides buffering for the direct contact between the backlight module 10 and the first rubber frame 21, avoiding damage and effectively preventing damage to the backlight module 10.

[0072] Based on the same inventive concept, the present utility model also provides a display device, including the display module described in any of the above embodiments.

[0073] By adopting the display module in the above embodiments, it is possible to make the border of the display device narrower and the thickness thinner, realizing the thin and light of the display device, increasing the screen-to-body ratio of the display device, improving the display effect, and enhancing the market competitiveness of the display device.
