[0038] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort should fall within the protection scope of the present application.

[0039] As shown in Figure 1 , the edge of the display screen in the prior art shows color deviation, which is more obvious when the edge of the display screen is a white frame. As shown by the dashed frame, the left white frame shows a blue deviation, and the right white frame shows a yellow deviation. The inventors of the present application have found through experimental analysis that this is because the white color of the display panel is formed by mixing three primary colors, i.e., red, green and blue. Since the edge of the backlight module is black material, the black material absorbs the light of the sub-pixels close to the edge. The display panel is usually arranged from left to right in red sub-pixels, green sub-pixels and blue sub-pixels, and the sub-pixels in the same column have the same color, i.e., the light of the red sub-pixels and green sub-pixels close to the left is absorbed, resulting in a blue deviation of the white screen; the light of the blue sub-pixels close to the right is absorbed, and the white screen is a mixture of red sub-pixels and green sub-pixels, i.e., a yellow deviation.

[0040] To solve the above problem, according to the first aspect of the present application, as shown in Figures 2 to 4B , a display module 1 is provided, comprising a backlight module 10 and a display panel 20, the backlight module 10 comprises a back frame 11 and a middle frame 12 arranged at the edge of the back frame 11; the display panel 20 is arranged at the light emitting side of the backlight module 10, and the display panel 20 comprises a display part 201 and a non-display part 202 arranged at the periphery of the display part 201; wherein the middle frame 12 comprises a top plate 121 and a side plate 122 connected; the top plate 121 is arranged between the non-display part 202 and the back frame 11, and the side plate 122 is arranged at the periphery of the back frame 11, and the reflectivity of the side wall 121a of the side of the top plate 121 away from the side plate 122 is greater than the reflectivity of the side wall 121b of the side of the top plate 121 close to the side plate 122.

[0041] The display module 1 can be a liquid crystal display module. The display panel 20 and the backlight module 10 are combined into one body. The display panel 20 is a non-self-luminous panel, which needs to be provided with a backlight source by the backlight module 10. The backlight source is a white planar light source.

[0042] As shown in Figure 3A and Figure 4AAs shown, the display module 1 further comprises an adhesive portion 30 arranged between the non-display portion 202 and the middle frame 12. The adhesive portion 30 is adhered to the non-display portion 202 at a side close to the display panel 20, and is adhered to the first sub-portion 1211 at a side close to the backlight module 10. The adhesive portion 30 is used to fix the display panel 20 to the middle frame 12.

[0043] In some embodiments, the material of the adhesive portion 30 can be a foam tape, but is not limited thereto.

[0044] Optionally, as shown in Figure 3B and Figure 4B In some embodiments, the top wall of the top plate 121 away from the side plate 122 is provided with a protrusion 1210, wherein the protrusion 1210 is located at an end of the top plate 121 close to the display portion 201. The adhesive portion 30 is arranged at a side of the protrusion 1210 away from the display portion 201. The protrusion 1210 can block the adhesive portion 30, preventing the adhesive portion 30 from entering the light emitting area of the backlight module 10. As shown in Figure 3A and Figure 4A The display panel 20 can be an LCD panel. The display panel 20 comprises a first substrate 22 and a second substrate 23 opposite and spaced apart, and a liquid crystal layer (not shown in the figure) arranged between the first substrate 22 and the second substrate 23. By applying different electric fields to the liquid crystal molecules in the liquid crystal layer and changing their orientation, the light transmittance of the display panel 20 is controlled, and thus the brightness of the display image is controlled. A color filter layer is arranged on one of the first substrate 22 or the second substrate 23, which can convert white light into colored light to present a color image.

[0045] As shown in Figure 3A and Figure 4A The first substrate 22 is arranged at a side of the second substrate 23 away from the backlight module 10. The upper surface of the first substrate 22 is provided with a first polarizer 21, and the lower surface of the second substrate 23 is provided with a second polarizer 24. As shown in Figure 3A and Figure 4A The size of the second polarizer 24 can be smaller than the size of the first polarizer 21, so that the adhesive portion 30 is adhered to the second substrate 23 instead of the lower surface of the second polarizer 24. Through the above arrangement, the overall thickness of the display module 1 can be reduced.

[0046] Optionally, in some embodiments, the side wall of the display panel 20 is flush with the side wall of the backlight module 10, thereby reducing the frame width of the display module 1.

[0047] As shown in Figure 2As shown, the display panel 20 includes a display part 201 and a non-display part 202 arranged at the periphery of the display part 201. The display part 201 can be provided with a plurality of sub-pixels 25, which can include red sub-pixels 251, green sub-pixels 252, and blue sub-pixels 253, thereby realizing color display. The non-display part 202 can be provided with a driving circuit, such as a gate driving circuit, which can provide driving signals for the sub-pixels 25.

[0048] As shown in Figure 3A and Figure 4A The backlight module 10 includes a back frame 11 and a middle frame 12 arranged at the edge of the back frame 11. The material of the back frame 11 can be metal materials such as stainless steel, iron, aluminum, etc. The back frame 11 includes a bottom plate and a baffle plate arranged at the periphery of the bottom plate, and the baffle plate and the bottom plate jointly form an accommodation space. The light source assembly 13 can be arranged in the accommodation space of the back frame 11.

[0049] The light source assembly 13 can include a reflective sheet 131, a light guide plate 132, and an optical film sheet 133 stacked in sequence. The sidewall of one side of the light guide plate 132 can be provided with a lamp strip, and the lamp strip includes a plurality of lamp beads, which can be LEDs, etc. The light emitted from the lamp beads is incident to the sidewall of the light guide plate 132, and is conducted to the entire plane of the light guide plate 132 through the light guide plate 132, thereby forming a plane light source. The material of the light guide plate 132 can be transparent polymer materials such as polymethyl methacrylate (PMMA) or polycarbonate (PC), etc.

[0050] The reflective sheet 131 is arranged at the side of the light guide plate 132 close to the bottom plate. The reflective sheet 131 is mainly used for reflecting the light emitted from the bottom of the light guide plate 132 back into the light guide plate 132, so that it can be concentrated from the front, reducing light loss and increasing the light source efficiency of the backlight module 10.

[0051] Optionally, in some embodiments, as shown in Figure 3A and Figure 4A A reflective strip 134 can be arranged on the sidewall of the light guide plate 132 which is not provided with a lamp strip, and the reflective strip 134 is used for reflecting the light emitted from the side of the light guide plate 132, so that it can be concentrated from the front, further reducing light loss and increasing the light source efficiency of the backlight module 10.

[0052] The optical film sheet 133 is arranged at the side of the light guide plate 132 away from the bottom plate. The optical film sheet 133 can include a diffusion sheet, a prism sheet, etc. stacked in sequence. The diffusion sheet is used for diffusely reflecting the light emitted from the light guide plate 132, so that the light is uniformly distributed on the light emitting surface, effectively homogenizing the light. The prism sheet is arranged at the side of the diffusion sheet away from the light guide plate 132, and the prism sheet corrects the direction of the light through the principle of refraction and reflection of light, concentrates the scattered light to the front, and improves the brightness of the backlight module 10.

[0053] The light-emitting surface of the backlight module 10 refers to the side surface of the optical film 133 that faces away from the base plate. The light-emitting surface of the backlight module 10 is provided corresponding to the display unit 201, which means that the backlight module 10 can provide a planar light source for at least the entire display unit 201.

[0054] The middle frame 12 is used to fix the light source assembly 13 of the backlight module 10, ensuring the structural stability of the backlight module 10, and also playing a certain role in light shielding and protection.

[0055] In some embodiments, the material of the middle frame 12 can be plastic or the like. The top plate 121 and the side plate 122 can be integrally formed by injection molding. Specifically, after heating and melting the plastic raw material, it is injected into a specific mold cavity, cooled and solidified in the mold, and the top plate 121 and the side plate 122 are formed in one step.

[0056] like Figure 3A and Figure 4A As shown, the side plate 122 is disposed on the periphery of the back frame 11. The side plate 122 can be snapped into the back frame 11, but is not limited thereto. The top plate 121 is disposed between the non-display part 202 and the back frame 11. The top plate 121 can extend into the receiving space of the back frame 11 and overlap with the edge of the optical film 133, thereby fixing the optical film 133 and preventing the optical film 133 from coming out of the back frame 11.

[0057] It should be understood that the top plate 121 does not overlap with the display unit 201, thereby preventing the top plate 121 from blocking the light emitted from the light-emitting surface of the backlight module 10 and incident on the display unit 201.

[0058] Reflectivity refers to the ratio of the luminous flux reflected from the surface of an object to the luminous flux incident on that surface, usually expressed as a percentage or decimal. A higher reflectivity means less light is absorbed when it strikes the object's surface; a lower reflectivity means more light is absorbed. By making the reflectivity of the sidewall 121a of the top plate 121 away from the side plate 122 greater than the reflectivity of the sidewall 121b of the top plate 121 closer to the side plate 122, the absorption of light emitted from the display unit 201 by the sidewall 121a of the top plate 121 away from the side plate 122 is reduced, thus improving the color shift of the displayed image caused by light absorption. Simultaneously, the reflectivity of the sidewall 121b of the top plate 121 closer to the side plate 122 is lower, making it less likely to be observed by the user after assembly into the display terminal 2, and therefore not affecting the appearance of the display terminal 2.

[0059] It should be noted that light-colored materials have a higher reflectivity than dark-colored materials. Therefore, the reflectivity of the sidewalls of the top plate 121 can be adjusted by changing the color of the sidewalls. For example, the sidewall 121a of the top plate 121 away from the side plate 122 can be set to white, gray, or other light colors; while the sidewall 121b of the top plate 121 closer to the side plate 122 can be set to black or other dark colors, thereby making the reflectivity of the sidewalls 121 more reflective. Figure 4A The reflectivity of the sidewall 121a on the side of the top plate 121 away from the side plate 122 is greater than the reflectivity of the sidewall 121b on the side of the top plate 121 closer to the side plate 122.

[0060] In some embodiments, the color of the plastic can be achieved by thoroughly mixing a masterbatch of a specific color with base resin particles. Through processing such as high-temperature melt extrusion, the pigment or dye in the masterbatch is uniformly dispersed in the base resin, giving the plastic particles a specific color. These colored plastic particles are then processed through molding processes such as injection molding and extrusion to form a top plate 121 with the corresponding color.

[0061] In some embodiments, colored plastic raw materials may also be used to make the top plate 121. Such as polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), etc., raw material particles with different colors.

[0062] It should be noted that plastic parts with different colors can be formed using a two-color injection molding process. The two-color injection molding process uses a two-color injection molding machine to inject two different colors of plastic into the same mold cavity one after another, forming a middle frame 12 with two colors in one step. This method can make different parts of the top plate 121 present different colors.

[0063] Optionally, such as Figure 3A and Figure 4A As shown, the top plate 121 includes a first sub-part 1211 and a second sub-part 1212, the second sub-part 1212 being disposed on the side of the first sub-part 1211 near the display unit 201; wherein, the reflectivity of the second sub-part 1212 is greater than the reflectivity of the first sub-part 1211.

[0064] The first sub-part 1211 and the second sub-part 1212 can be made of different colored plastics. For example, the first sub-part 1211 can be black or other dark-colored plastic. The first sub-part 1211 is located on the periphery of the back frame 11. After assembly into the display terminal 2, the first sub-part 1211 is not easily observed and will not affect the appearance of the display terminal 2. The second sub-part 1212 can be gray, white, or other light-colored plastic. The second sub-part 1212 has a higher reflectivity and absorbs less light, which can reduce the absorption of light by the edge of the top plate 121 on the pixels, thereby improving the light mixing uniformity of the red sub-pixel 251, green sub-pixel 252, and blue sub-pixel 253 and reducing color shift.

[0065] In some embodiments, the first sub-part 1211 and the second sub-part 1212 can be made by a two-color injection molding process.

[0066] The color or white color master batch is mixed with the base resin particles, and after high-temperature melting extrusion and other processing processes, the color or white color pigment is uniformly dispersed in the base resin, so that the plastic particles have color or white color. The color or white plastic particles are used as the material of the top plate 121.

[0067] Specifically, the first sub-part 1211 can be made of black or other dark plastic; the second sub-part 1212 can be made of white, gray or other light plastic. Two different colors of plastic are injected into the same mold cavity in turn by a two-color injection molding process, and the first sub-part 1211 and the second sub-part 1212 with two colors are formed at one time.

[0068] Alternatively, as shown in Figures 3A to 4B The second sub-part 1212 covers the side wall of the first sub-part 1211 close to the display part 201, and the second sub-part 1212 covers the bottom wall of the first sub-part 1211 close to the back frame 11.

[0069] Because the color of the first sub-part 1211 is darker than that of the second sub-part 1212, the first sub-part 1211 is more likely to absorb light at the edge of the backlight module 10 than the second sub-part 1212. The side wall of the first sub-part 1211 close to the display part 201 and the bottom wall of the first sub-part 1211 close to the back frame 11 are the main light absorption surfaces. Therefore, the second sub-part 1212 covers the light absorption surface of the first sub-part 1211, so that the second sub-part 1212 shields the first sub-part 1211, avoiding the light being absorbed after being incident on the first sub-part 1211, thereby improving the color cast of the display picture.

[0070] Alternatively, the first sub-part 1211 and the second sub-part 1212 are integrally formed. The first sub-part 1211 and the second sub-part 1212 can be integrally formed by two-color injection molding, but are not limited thereto.

[0071] Alternatively, as shown in Figure 4B The second sub-part 1212 also covers part of the top wall of the first sub-part 1211 close to the display part 201, and the top wall is arranged opposite to the bottom wall. In order to ensure that the side wall of the first sub-part 1211 close to the display part 201 can be completely covered by the second sub-part 1212, the second sub-part 1212 can be extended to the side of the top wall of the first sub-part 1211 close to the display part 201.

[0072] Alternatively, the first sub-part 1211 is a plastic part, and the second sub-part 1212 is a coating.

[0073] In some embodiments, the first sub-portion 1211 can be made by an injection molding process, and the second sub-portion 1212 can be formed by a surface treatment method.

[0074] The surface treatment method can include spraying, electroplating, printing, and the like. Among them, spraying refers to spraying a pigment layer on the surface of an object by a spray gun or the like to form a colored coating, thereby imparting the desired color to the object. Electroplating refers to plating a thin film of metal or alloy with color on the surface of an object by an electroplating process, such as copper plating, nickel plating, chromium plating, etc. These metal layers can exhibit different colors and luster. Printing refers to printing ink on the surface of a rubber frame to form patterns or colors using screen printing, pad printing, and the like.

[0075] It should be noted that the second sub-portion 1212 is a coating layer with a small thickness, and the second sub-portion 1212 is formed on part of the surface of the first sub-portion 1211 by a surface treatment method. Specifically, as shown in Figure 4B , the coating layer covers the side wall of the side of the first sub-portion 1211 close to the display portion 201, the bottom wall of the side of the first sub-portion 1211 close to the back frame 11, and the top wall of part of the first sub-portion 1211 close to the display portion 201.

[0076] Since the coating layer can be formed by a surface treatment method, the original middle frame mold can be reused, and the cost increase due to mold repair can be reduced.

[0077] Optionally, as shown in Figure 3B and Figure 4B , the angle A between the side wall 121a of the side of the top plate 121 away from the side plate 122 and the side surface of the top plate 121 away from the back frame 11 is 0 to 20 degrees. For example, the angle A can be 0 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, etc.

[0078] When the angle A is greater than 0 degrees, the mold angle can be increased, thereby making the middle frame 12 more easily demolded. When the angle A is equal to 0 degrees, the overlapping area of the top plate 121 and the optical film 133 can be increased without increasing the width of the top plate 121, thereby increasing the width of the top plate 121 to the optical film 133, so that the optical film 133 is not easily pulled out of the back frame 11.

[0079] Optionally, as shown in Figure 3A and Figure 4A , the distance s between the orthographic projection of the side wall 121a of the side of the top plate 121 away from the side plate 122 on the display panel 20 and the display portion 201 is 0.5 to 1.0 mm. By the above setting, the top plate 121 can not block the light rays emitted from the light emitting surface of the backlight module 10 and incident on the display portion 201.

[0080] In some embodiments, the distance s can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.
