Obviously, the drawings described below are only some embodiments of the invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0028] The following descriptions of the embodiments are with reference to the attached diagrams to illustrate specific embodiments that the present application can be implemented in. The directional terms mentioned in the present application, such as [up], [down], [front], [back], [left], [right], [inside], [outside], [side], etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present application, rather than to limit the present application. In the figures, units with similar structures are represented by the same reference numerals. In the accompanying drawings, the thickness of some layers and regions is exaggerated for clear understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited to this.

[0029] In view of the obvious visual difference of the four-sided borderless design, the inventor of the present application found in the research that it is mainly because the protective member in the liquid crystal display module replaces the decorative strip on the liquid crystal display device, and the protective member is located above the upper polarizer. There is a relatively large height difference between the protective member and the upper polarizer, which leads to obvious visual difference. Specifically, refer to Figure 1 , Figure 1 As an introduction to the embodiments of the present application, a partial cross-sectional structural schematic diagram of a display module is provided. The display module includes a backlight module 10' and a display panel 20' arranged on the light-emitting side of the backlight module 10'. The display panel 20' includes an array substrate 21' and a color film substrate 22' arranged relatively to each other, and a first polarizer 23' (i.e., an upper polarizer) located on the side of the color film substrate 22' away from the array substrate 21'. The display module also includes a protective member 30' arranged on the outside of the backlight module 10', and the protective member 30' is also located above part of the first polarizer 23' to replace the decorative strip on the whole machine, thereby reducing the thickness of the decorative strip of the whole machine and achieving a visual borderless effect on all four sides. However, after the protective member 30' replaces the decorative strip on the whole machine, the protective member 30' is located above the upper polarizer, and there is a relatively large height difference between the protective member 30' and the upper polarizer, resulting in obvious visual differences.

[0030] To this end, the present application provides a display module and a display device.

[0031] Please refer to Figure 1 and Figure 2 , Figure 2A partial cross-sectional structural schematic diagram of a display module provided in an embodiment of the present application. The display module 100 includes a backlight module 10, a display panel 20 and a decorative strip 30. The backlight module 10 includes a frame 11, and the frame 11 is formed with a receiving cavity 110. In the thickness direction of the display module 100, the height of the frame 11 is less than the height of the display panel 20. The display panel 20 is arranged on the light-emitting side of the backlight module 10, and is located above the receiving cavity 110, and is fixedly connected to the frame 11 of the backlight module 10, for example, the display panel 20 can be fixedly connected to the frame 11 of the backlight module 10 through a first adhesive layer 40. The display panel 20 is a liquid crystal display panel 20, and the display panel 20 includes an array substrate 21 and a color filter substrate 22 arranged opposite to each other, and a first polarizer 23 arranged on a side of the color filter substrate 22 away from the array substrate 21.

[0032] Of course, the display panel 20 further includes a liquid crystal layer and a sealant disposed between the array substrate 21 and the color filter substrate 22, and a second polarizer 24 disposed on a side of the array substrate 21 away from the color filter substrate 22. The sealant surrounds the liquid crystal layer to seal the liquid crystal layer.

[0033] The color filter substrate 22 is located on a side of the array substrate 21 away from the backlight module 10. The color filter substrate 22 is set inwardly. The array substrate 21 relatively forms a first protruding portion 211 protruding from the edge of the color filter substrate 22. The first protruding portion 211 is also the portion where the outer boundary of the array substrate 21 exceeds the outer boundary of the color filter substrate 22. In other words, the outer contour of the color filter substrate 22 is located within the outer contour of the array substrate 21 and is smaller than the outer contour of the array substrate 21. The first protruding portion 211 is the portion of the array substrate 21 that is not covered by the color filter substrate 22. The first protruding portion 211 is used to set peripheral circuits, etc. For example, a binding circuit can be set on the first protruding portion 211, and the binding circuit is used to bind circuit boards, etc.

[0034] Exemplarily, the display module 100 includes a display area and a frame area outside the display area, the first protrusion 211 is located in the frame area, and the array substrate 21 is provided with a plurality of array-arranged sub-pixels corresponding to the display area. Exemplarily, each of the sub-pixels includes a pixel driving circuit and a first electrode, and the pixel driving circuit is electrically connected to the first electrode to provide a driving signal to the first electrode. The color filter substrate 22 includes a second electrode and a color filter layer, and an electric field is formed between the second electrode and the first electrode to drive the liquid crystal molecules of the liquid crystal layer to deflect, so as to control the transmittance of the backlight of the backlight module 10, however, the structure of the sub-pixel is not limited thereto, for example, the second electrode and the color filter layer can also be provided on the array substrate 21. The color filter layer includes a plurality of color filter blocks of different colors and a black matrix located between adjacent color filter blocks, and the color filter blocks of different colors include a red color filter block, a green color filter block and a blue color filter block, and each color filter block corresponds to one sub-pixel. It should be noted that the description of the specific structures of the array substrate 21 and the color filter substrate 22 in this embodiment is only an example, and the present application is not limited to this. For example, the second electrode can also be provided on the array substrate 21 of the present application, so there is no need to provide the second electrode on the color filter substrate 22.

[0035] The decorative strip 30 is arranged on the outside of the frame 11 of the backlight module 10 and is located in the border area. The decorative strip 30 includes a first protection portion 31 and a covering portion 32. The first protection portion 31 is arranged on the side of the first protrusion 211 away from the backlight module 10, and the covering portion 32 is attached to the side of the first protection portion 31 away from the first protrusion 211. For example, the covering portion 32 is attached to the first protection portion 31 through a second adhesive layer 41. The decorative strip 30 is used to protect the binding circuit arranged on the first protrusion 211 and the circuit board bound to the binding circuit. Of course, in order to better protect the circuit board bound to the binding circuit, the decorative strip 30 also protects the second protection portion 33 connected to the first protection portion 31, and the second protection portion 33 extends along the thickness direction of the display module 100.

[0036] In the thickness direction of the display module 100, the surface height of the first protective portion 31 is less than or equal to the surface height of the first polarizer 23. The covering portion 32 cooperates with the first protective portion 31 to reduce or eliminate the height difference between the first protective portion 31 and the first polarizer 23, so as to reduce the visual difference, thereby visually getting closer to the true four-sided borderless effect, thereby improving the problem of obvious visual difference in the existing four-sided borderless design.

[0037] Among them, the "surface height" of a certain structure in the present application is the maximum vertical height of the structure compared to a specific reference plane, that is, the vertical distance of the top surface of the structure from the specific reference plane. For example, the surface height of the first protecting portion 31 refers to the maximum vertical height of the first protecting portion 31 compared to the array substrate 21, that is, the vertical distance between the top surface of the first protecting portion 31 and the array substrate 21. The top surface of the first protecting portion 31 refers to the surface of the first protecting portion 31 facing away from the side of the first protrusion 211.

[0038] Correspondingly, the surface height of the first polarizer 23 refers to the maximum vertical height of the first polarizer 23 compared to the array substrate 21, that is, the vertical distance between the top surface of the first polarizer 23 and the array substrate 21, and the top surface of the first polarizer 23 refers to the surface of the first polarizer 23 facing away from the color film substrate 22.

[0039] Thus, in the thickness direction of the display module 100, the surface height of the first protection portion 31 is less than or equal to the surface height of the first polarizer 23, that is, in the thickness direction of the display module 100, the vertical distance between the top surface of the first protection portion 31 and the array substrate 21 is less than or equal to the vertical distance between the top surface of the first polarizer 23 and the array substrate 21. In other words, the top surface of the first protection portion 31 is flush with the top surface of the first polarizer 23 or the top surface of the first protection portion 31 is lower than the top surface of the first polarizer 23, thereby reducing or eliminating the height difference between the first protection portion 31 and the first polarizer 23. The covering portion 32 is attached to the first protection portion 31, so that the covering portion 32 cooperates with the first protection portion 31, thereby more conducive to adjusting the height difference between the first protection portion 31 and the first polarizer 23.

[0040] The thickness of the covering portion 32 is less than that of the first protecting portion 31, so as to better adjust the height difference between the first protecting portion 31 and the first polarizer 23. In this application, the thickness of a structure refers to the thickness of the structure in the thickness direction of the display module 100, for example, the thickness of the covering portion 32 refers to the thickness of the covering portion 32 in the thickness direction of the display module 100, and for another example, the thickness of the first protecting portion 31 refers to the thickness of the first protecting portion 31 in the thickness direction of the display module 100.

[0041] In one embodiment, the covering portion 32 extends from the first protection portion 31 to the top of the color film substrate 22, the first polarizer 23 is set inward, and the color film substrate 22 relatively forms a second protruding portion 221 protruding from the edge of the first polarizer 23, and the covering portion 32 is bonded to the second protruding portion 221, for example, the covering portion 32 is bonded to the second protruding portion 221 through a third bonding layer 42, and the third bonding layer 42 and the second bonding layer 41 can select different or the same type of adhesive materials with adhesiveness according to the material of the bonded structure. The definition of the second protruding portion 221 can refer to the definition of the first protruding portion 211, and will not be repeated here.

[0042] Optionally, the covering portion 32 abuts against the first polarizer 23 so that the top surface of the display module 100 is continuous to reduce visual differences. Of course, in some other embodiments, in order to reduce the difficulty of fitting the above-mentioned covering portion 32, a smaller gap may be reserved between the covering portion 32 and the first polarizer 23. Moreover, in the thickness direction of the display module 100, the surface height of the covering portion 32 is the same as the surface height of the first polarizer 23, that is, the top surface of the covering portion 32 is flush with the top surface of the first polarizer 23 to further reduce visual differences, thereby visually closer to a true four-sided borderless effect. Among them, the surface height of the covering portion 32 can refer to the definition of the surface height of the first protective portion 31, which will not be repeated here.

[0043] The specific structure of the display module 100 will be described in detail below:

[0044] Continue to refer to Figure 2 The backlight module 10 further includes a light guide plate 12 and a light source 13. The frame 11 is formed with a housing cavity 110 for housing and protecting the light guide plate 12 and the light source 13. The light guide plate 12 and the light source 13 are arranged in the housing cavity 110 and are fixedly connected to the frame 11. The light source 13 is located on at least one side surface of the light guide plate 12, wherein the side surface of the light guide plate 12 is connected between the upper surface and the lower surface of the light guide plate 12, the upper surface of the light guide plate 12 is the light emitting surface of the light guide plate 12, the lower surface of the light guide plate 12 is arranged opposite to the upper surface, and the side surface of the light guide plate 12 opposite to the light source 13 is the light incident surface of the light guide plate 12.

[0045] Of course, the backlight module 10 may also include other optical films such as a reflective sheet 14 disposed on the lower surface of the light guide plate 12 and a brightness enhancement film 15 disposed on the upper surface of the light guide plate 12. The reflective sheet 14 is used to reflect the light leaking from the lower surface of the light guide plate 12 to improve the utilization rate of the light. The brightness enhancement film 15 is used to increase the brightness of the light emitted from the light guide plate 12.

[0046] Optionally, the frame body 11 includes a back plate 111 and a rubber frame 112. The back plate 111 includes a bottom plate 1111 and a side plate 1112 surrounding the bottom plate 1111. The back plate 111 may be a metal back plate 111, such as an aluminum back plate 111. The bottom plate 1111 is provided with a recessed portion at a position corresponding to the light source 13, and the recessed portion is used to provide an escape space when assembling the light source 13, so as to improve the overall strength of the back plate 111. The light source 13 is fixed to the inner side wall of the side plate 1112, for example, the light source 13 may be fixedly connected to the inner side wall of the side plate 1112 through a fourth adhesive layer 43, and the inner side wall of the side plate 1112 refers to the inner wall of the accommodating cavity 110.

[0047] The plastic frame 112 is fixed on the side panel 1112, and the plastic frame 112 is in a "T" shape. For example, the plastic frame 112 includes a first sub-section and a second sub-section extending along the thickness direction of the display module 100, and the first sub-section and the second sub-section are connected. The plastic frame 112 also includes a third sub-section connected between the first sub-section and the second sub-section, and the extension direction of the third sub-section is different from that of the first sub-section and the second sub-section. The first sub-section is arranged on the outer side wall of the side, the third sub-section is arranged at the end of the side panel 1112, and the second sub-section is located on the side of the third sub-section away from the first sub-section. The array substrate 21 is fixedly connected to one side of the third sub-section through the first adhesive layer 40, and the light guide plate 12 is fixedly connected to the other side of the third sub-section through the fifth adhesive layer 44.

[0048] The first protection portion 31 is disposed at the end of the second sub-portion, and the second protection portion 33 is located at a side of the plastic frame 112 away from the accommodating cavity 110. Specifically, the second protection portion 33 is disposed on the outer wall of the second sub-portion and extends from the outer wall of the second sub-portion to the outer wall of the first sub-portion. The first protection portion 31 is also disposed corresponding to the light source 13, and the second protection portion 33 cooperates with the first protection portion 31 to semi-enclose the plastic frame 112.
