[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The components of the embodiments of the present disclosure generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the present disclosure for protection, but merely represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present disclosure.

[0037] Figure 1 is a schematic diagram of an exemplary structure of a display module, such as Figure 1 As shown, the display module includes: a backlight structure 101, a display panel 102 and a back plate 103. The back plate 103 includes: a first back plate 1031 and a second back plate 1032. The backlight structure 101 and the display panel 102 are assembled separately, and two back plates 103, namely the first back plate 1031 and the second back plate 1032 are required for support. The process is relatively complicated and the production cycle is long. At the same time, due to the existence of multiple back plates 103 (the first back plate 1031 and the second back plate 1032), the thickness of the display module is relatively thick and the frame is relatively wide, which is not conducive to the thinness of the display module.

[0038] Figure 2 is a schematic diagram of the structure of another exemplary display module, such as Figure 2 As shown, the display module includes: a backlight structure 101, a display panel 102 and a back plate 103. The backlight structure 101 and the display panel 102 are directly assembled in the same back plate 103. Figure 1 Compared with the display module shown in the figure, one of the second back plates 1032 and other structures such as tapes can be reduced, which can simplify the assembly process, shorten the production cycle, and reduce the thickness and frame of the display module.

[0039] However, current display modules are generally single-sided displays, and their back panels 103 (first back panels 1031) are generally made of metal or plastic materials, and are often processed by surface sandblasting, oxidation, etc., and are unable to display product logos, background images, or screen saver images. The back side is relatively simple and cannot meet users' demands for diversified products.

[0040] In order to solve at least one of the above-mentioned technical problems, the embodiments of the present disclosure provide a display module and a display device. The display module and the display device provided by the embodiments of the present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] In a first aspect, an embodiment of the present disclosure provides a display module, Figure 3 A schematic diagram of the structure of a display module provided in an embodiment of the present disclosure is shown in FIG. Figure 4 A schematic diagram of the structure of another display module provided in an embodiment of the present disclosure is shown in FIG. Figure 3 and Figure 4 As shown, the display module includes: a backlight structure 101; the backlight structure 101 includes: a light guide plate 1011; the light guide plate 1011 has a first light emitting surface and a second light emitting surface arranged opposite to each other; the backlight structure 101 also includes: a reflective sheet 1012 and a first light enhancing sheet 1013 which are located on one side of the first light emitting surface of the light guide plate 1011 and are arranged in sequence; the display module also includes: a display panel 102 located on the second light emitting surface of the light guide plate 1011, and a back plate 103 located on the side of the first light enhancing sheet 1013 away from the light guide plate 1011; at least part of the area of ​​the back plate 103 is a light-transmitting area; part of the light in the light guide plate 1011 is emitted from the first light emitting surface through the reflective sheet 1012, the first light enhancing sheet 1013, and the light-transmitting area of ​​the back plate 103 in sequence, and part of the light is emitted from the second light emitting surface through the display panel 102.

[0042] The light guide plate 1011 can fully reflect the light, so that the light is transmitted inside the light guide plate 1011, ensuring that the light can be transmitted to the entire area of ​​the display panel 102 and the back plate 103 to ensure the display effect of the double-sided display. The light guide plate 1011 has a first light emitting surface and a second light emitting surface that are arranged opposite to each other, wherein the first light emitting surface is Figure 3 and Figure 4 The lower surface of the light guide plate 1011 in the display module shown in the figure, that is, the surface close to the back plate 103, the second light emitting surface is Figure 3 and Figure 4 The upper surface of the light guide plate 1011 in the display module shown is the surface close to the display panel 102. Due to the transmission angle of light in the light guide plate 1011, not all angles of light are totally reflected, resulting in light being emitted from both the first light emitting surface and the second light emitting surface of the light guide plate 1011.

[0043] The reflective sheet 1012 is located on the first light emitting surface of the light guide plate 1011, that is, the side close to the back plate 103. The reflective sheet 1012 can be made of a silver reflective sheet, a white reflective sheet, a reflective tape or the like. Its reflectivity can be greater than 95% and less than 100%. Most of the light emitted from the first light emitting surface of the light guide plate 1011 can be directly reflected into the light guide plate 1011, and emitted from the side of the light guide plate 1011 close to the display panel 102, thereby ensuring that most of the light is used for the display function of the display panel 102.

[0044] The first brightness enhancement film 1013 is located on the side of the reflective film 1012 close to the back plate 102 . Due to process limitations, it is not easy for the reflective film 1012 to reach 100% reflectivity, so a small part of the light in the light guide plate 1011 will be transmitted through the reflective film 1012 to the first brightness enhancement film 1013 .

[0045] The first brightness enhancement film 1013 may specifically be a structure such as a prism, a lens, or a grating, which can converge the light transmitted by the reflective film 1012 to increase the intensity of the light, so that the light-transmitting area of ​​the back panel 103 can also realize the display function, thereby ensuring the brightness of the display image displayed by the back panel 103, thereby improving the user experience.

[0046] At the same time, the light from the second light emitting surface of the light guide plate 1011 can be irradiated to the display panel 102 and emitted by the display panel 102, so that the display module can achieve a double-sided display effect to meet users' needs for diversified products.

[0047] In the display module provided by the embodiment of the present disclosure, the backlight structure 101 and the display panel 102 are directly assembled in the same back plate 103, which can simplify the assembly process, shorten the production cycle, and reduce the thickness and frame of the display module. Furthermore, part of the light transmitted by the light guide plate 1011 of the backlight structure 101 can be emitted from the first light emitting surface through the reflective sheet 1012, the first light-enhancing sheet 1013, and the light-transmitting area of ​​the back plate 103 in sequence, providing a light source for the light-transmitting area of ​​the back plate 103, so that the light-transmitting area of ​​the back plate 103 can realize the display function. Part of it can be emitted through the display panel 102, providing a light source for the display panel 102, so that the display panel 102 realizes the display function. In this way, the display module can achieve a double-sided display effect, and the light-transmitting area of ​​the back plate 103 can form a preset pattern according to actual needs to display the logo, background picture or screen saver picture of the product and other patterns to meet the user's demand for product diversification.

[0048] It should be noted here that the display panel 102 can specifically be a liquid crystal display panel, which may include an array substrate and a color filter substrate (not shown in the figure) that are relatively arranged, and a liquid crystal layer between the array substrate and the color filter substrate, wherein the array substrate is provided with circuit structures such as a pixel driving circuit, which can provide pixel voltages and common voltages to pixel electrodes and common electrodes respectively to form a driving electric field to drive the liquid crystal molecules in the liquid crystal layer to deflect, thereby realizing the display function.

[0049] Meanwhile, the display panel 102 is also attached with structures such as a polarizer and an alignment layer (not shown in the figure), which can be configured with reference to the structures in the related art and will not be described in detail here.

[0050] In some embodiments, Figure 3 and Figure 4 As shown, the backlight structure 101 further includes: a second brightness enhancement sheet 1014 ; the second brightness enhancement sheet 1014 is located on a side of the light guide plate 1011 close to the display panel 102 .

[0051] In some embodiments, Figure 3 and Figure 4 As shown, the backlight structure 101 further includes: a second brightness enhancement sheet 1014 ; the second brightness enhancement sheet 1014 is located on a side of the light guide plate 1011 close to the display panel 102 .

[0052] The second brightness enhancement sheet 1014 may be a structure such as a prism, a lens, or a grating, which can converge light to increase the intensity of light and ensure the brightness of the display image displayed by the display panel 102, thereby improving the user experience.

[0053] In some embodiments, Figure 3 and Figure 4 As shown, the backlight structure 101 further includes: a backlight source 1015 : the backlight source 1015 is located at one end or both ends of the light guide plate 1011 .

[0054] The backlight source 1015 can adopt a structure such as a light-emitting diode (LED), which can emit light to provide a light source to the back panel 103 and the display panel 102. The light emitted by the backlight source 1015 can be incident from one end or both ends of the light guide plate 1011, that is, the light incident side of the light guide plate 1011, and transmitted through the light guide plate 1011.

[0055] It should be noted here that Figure 3 and Figure 4 In the structure shown in the figure, only the backlight source 1015 is located at one end of the light guide plate 1011 as an example for description. The backlight source 1015 can also be located at both ends of the light guide plate 1011, that is, at Figure 3 and Figure 4In the structure shown, another group of backlight sources 1015 (not shown in the figure) is arranged at a position opposite to the existing backlight source 1015. In this way, the backlight source 1015 can inject light at both ends of the light guide plate 1011, avoiding light loss caused by too long transmission distance in the light guide plate 1011, thereby improving the brightness of the picture displayed by the display panel 102 and the back panel 103 of the display module.

[0056] In some embodiments, Figure 3 and Figure 4 As shown, the display module further includes: a cover plate 104 ; the cover plate 104 is located on a side of the display panel 102 away from the light guide plate 1011 .

[0057] The cover plate 104 can be made of transparent materials such as glass and acrylic to form a transparent cover plate to avoid blocking the light emitted by the display panel 102. At the same time, the display panel 102 and other structures can be protected to avoid damage to the display panel 102 and other structures caused by external forces during the preparation, transportation, and application process. In addition, the entire surface of the cover plate 104 is relatively flat, which can improve the user experience.

[0058] In some embodiments, Figure 3 and Figure 4 As shown, the display module further includes: a middle frame 105 ; the middle frame 105 includes: a first supporting portion 1051 and a receiving portion 1052 ; the cover plate 104 is located on the first supporting portion 1051 ; and the backlight source 1015 is embedded in the receiving portion 1052 .

[0059] The middle frame 105 can be made of metal materials such as aluminum, aluminum alloy, stainless steel, etc., which can reduce weight while ensuring high strength, which is conducive to lightweighting of the display module.

[0060] The edge of the middle frame 105 can form a first support portion 1051 through a groove cutting process, and the first support portion 1051 can support the cover plate 104 thereon. The first support portion 1051 and the cover plate 104 can be bonded together through an adhesive layer 106 to prevent the cover plate 104 from falling off the first support portion 1051, thereby ensuring the stability of the display module.

[0061] The adhesive layer 106 can be made of foam glue and other materials, which can ensure strong bonding and have certain buffering properties to prevent the first support part 1051 from damaging the cover plate 104. It is understandable that the adhesive layer 106 can also be made of other materials such as structural glue, which will not be listed here.

[0062] The edge of the middle frame 105 can form a receiving portion 1052 through a groove digging process, and the receiving portion 1052 can support the backlight source 1015 so that the backlight source 1015 can be embedded in the receiving portion 1052. This can avoid the backlight source 1015 occupying a large space in the display module, thereby ensuring the thinness of the display module.

[0063] Understandably, Figure 3 and Figure 4 In the display module shown, only the backlight source 1015 is located at one end of the light guide plate 1011 as an example for description, and the middle frame 105 is provided with only one accommodating portion 1052. When the backlight source 1015 is located at both ends of the light guide plate 1011, Figure 3 and Figure 4 The other side of the middle frame 105 in the display module shown is also grooved to form another accommodating portion 1052 (not shown in the figure) to accommodate another backlight source 1015. In this way, the backlight source 1015 can be incident with light at both ends of the light guide plate 1011 to avoid light loss caused by the long transmission distance of light in the light guide plate 1011, thereby improving the brightness of the picture displayed by the display panel 102 and the back panel 103 of the display module.

[0064] In some embodiments, Figure 3 As shown, the backplane 103 includes: a transparent backplane; the display module further includes: a color filter layer 107; the color filter layer 107 is located on the side of the transparent backplane close to the backlight structure 101, and forms a first preset pattern.

[0065] The back panel 103 can be made of transparent materials such as glass and acrylic to form a transparent back panel, wherein the light-transmitting area is the entire area of ​​the transparent back panel, and can transmit part of the light emitted by the light guide plate 1011 of the backlight structure 101.

[0066] The color filter layer 107 is located on the side of the transparent back panel close to the light guide plate 1011, and can filter the light transmitted by the light guide plate 1011 of the backlight structure 101 to form light of different colors. For example, the light transmitted by the light guide plate 1011 of the backlight structure 101 is white light, and the color filter layer 107 can include areas of different colors such as red, green, and blue, and can filter the white light into corresponding red light, filtered light, and blue light, etc.

[0067] The color filter layer 107 is formed with a first preset pattern, and under the illumination of the light transmitted by the light guide plate 1011 of the backlight structure 101, the first preset pattern can be presented as a color image and displayed on the back plate 103. In this way, the display module can achieve a double-sided display effect to meet the user's demand for diversified products.

[0068] It should be noted that the color filter layer 107 can be formed by using color ink and inkjet or printing technology, wherein the first preset pattern can be a relatively complex image such as a landscape image, an animal image, a building image, etc., and the picture formed by the first preset pattern can be the same as the background picture or screen saver picture displayed by the display panel 102 on the other side, that is, the background picture or screen saver picture can be displayed on the back panel 103. Among them, the first preset pattern can be set according to actual needs to meet the user's demand for customizable pictures displayed on the back panel 103.

[0069] In some embodiments, Figure 3 As shown, the edge of the reflective sheet 1012 is flush with the edge of the light guide plate 1011 ; the edges of the color filter layer 107 and the first brightness enhancement sheet 1013 are flush and both extend beyond the edge of the reflective sheet 1012 and extend toward the backlight source 1015 .

[0070] The edge of the reflective sheet 1012 is flush with the edge of the light guide plate 1011. The reflective sheet 1012 can reflect most of the light emitted from the first light emitting surface of the light guide plate 1011 directly into the light guide plate 1011, and emit it from the side of the light guide plate 1011 close to the display panel 102, ensuring that most of the light is used for the display function of the display panel 102.

[0071] The edges of the color filter layer 107 and the first brightness enhancement sheet 1013 are flush and both extend beyond the edge of the reflective sheet 1012 and extend toward the backlight source 1015. The color filter layer 107 can filter the light transmitted by the light guide plate 1011 of the backlight structure 101 to form light of different colors, so that the light is focused by the first brightness enhancement sheet 1013. At the same time, the light emitted by the backlight source 1015 and not irradiated to the light guide plate 1011 can be filtered to form light of different colors, so that the light is focused by the first brightness enhancement sheet 1013. In this way, the utilization rate of light can be improved and the power consumption of the backlight source 1015 can be reduced.

[0072] In some embodiments, Figure 3 As shown, the middle frame 105 further includes: a second support portion 1053 arranged opposite to the first support portion 1051 ; and the transparent back plate is located on the second support portion 1053 .

[0073] The edge of the middle frame 105 can form a second support portion 1053 through a grooving process, and the second support portion 1053 can support the transparent back panel thereon. The second support portion 1053 and the transparent back panel can be bonded together through an adhesive layer 106 to prevent the transparent back panel from falling off the second support portion 1053, thereby ensuring the stability of the display module.

[0074] In some embodiments, Figure 4As shown, the back plate 103 includes: a non-transparent back plate: the non-transparent back plate is provided with a plurality of hollow structures A in the light-transmitting area; the hollow structures A form a second preset pattern.

[0075] The back panel 103 can be made of non-transparent materials such as metal and plastic to form a non-transparent back panel. The non-transparent back panel is provided with a plurality of hollow structures A to form a light-transmitting area. The hollow structures A can transmit part of the light emitted by the backlight structure 101.

[0076] The plurality of hollow structures A may form a second preset pattern, and under the illumination of the light transmitted by the light guide plate 1011 of the backlight structure 101, the second preset pattern may be presented as a display image and displayed on the back plate 103. In this way, the display module can achieve a double-sided display effect, meeting the user's demand for product diversification.

[0077] It should be noted that the second preset pattern can be a relatively simple image such as a product logo, a geometric figure, or an English letter. Due to the process limitation of the hollow structure A, when the hollow structure A is used for transmission to realize double-sided display, the images formed are all images with relatively simple lines. Among them, the second preset pattern can be set according to actual needs to meet the user's demand for customizable images displayed on the back panel 103.

[0078] It is understandable that the above two methods can also be combined, that is, the color filter layer 104 is used while the back plate 103 is a non-transparent back plate. The implementation principle can refer to the above implementation principle and will not be described in detail here.

[0079] In some embodiments, Figure 4 As shown, the display module further includes: a transparent filling layer 108 located in the hollow structure A; the thickness of the transparent filling layer 108 is the same as the thickness of the back plate 103 .

[0080] The transparent filling layer 108 can be made of transparent materials such as acrylic, which can be filled in the hollow structure A. The hollow structure A can be flattened so that the thickness of the transparent filling layer 108 is the same as the thickness of the back panel 103. This ensures that while achieving double-sided display, the surface of the entire back panel 103 remains flat, meeting users' needs for product diversity and improving users' experience.

[0081] In some embodiments, Figure 4 As shown, the back plate 103 is located on a side of the middle frame 105 opposite to the first support portion 1051 , and the back plate 103 and the middle frame 105 are an integrally formed structure.

[0082] The back panel 103 and the middle frame 105 can be made of the same material and the same process. For example, both are made of aluminum or aluminum alloy material by die-casting process, which can reduce the process steps and save preparation costs, while enhancing the firmness of the back panel 103 and further increasing the stability of the display module performance.

[0083] In a second aspect, an embodiment of the present disclosure provides a display device, which includes a display module provided by any of the above embodiments. The display device can be, for example, a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a vehicle-mounted device, or any other product with a display function. Other essential components of the display device should be understood by a person of ordinary skill in the art, and will not be elaborated here, nor should they be used as a limitation to the present disclosure.

[0084] The following will be described in detail by taking a laptop computer as an example of the display device provided in the embodiment of the present disclosure. It can be understood that the implementation principles of other display devices are similar and will not be described in detail.

[0085] Figure 5 A schematic diagram of the structure of a notebook computer provided by an embodiment of the present disclosure is shown in FIG. Figure 5 As shown, the back panel 103 of the notebook computer is a transparent back panel, and its cross-sectional structure along the AA' direction can be as follows: Figure 3 As shown, a color filter layer 107 is also provided, and the color filter layer 107 is formed with a first preset pattern, for example, a landscape image, an animal image, a building image, etc. Under the illumination of the light transmitted by the light guide plate 1011 of the backlight structure 101, the first preset pattern can be presented as a color image and displayed on the back plate 103. In this way, the display module can achieve a double-sided display effect to meet the user's demand for diversified products.

[0086] Figure 6 A schematic diagram of the structure of another notebook computer provided by an embodiment of the present disclosure is shown in FIG.
