Description

Technical Field

[0001] The present application relates to the field of electronic technologies, and particularly to a liquid crystal display module. Background Art

[0002] Liquid crystal display modules have the advantages of being light, thin, and having low power consumption, and are widely used in modern information devices. Since the display panel in the liquid crystal display module itself does not have the property of emitting light, it relies on the sufficient and evenly distributed light source supplied by the backlight module to achieve the display function. Therefore, the performance of the backlight module directly affects the quality of the liquid crystal display module. In order to enhance the strength of the liquid crystal display module, the backlight module usually adopts a structure with a back plate, and the back plate and the rubber frame are usually assembled using buckles and tapes.

[0003] Currently, the rigidity of the middle area of the rubber frame is weakened. When assembling the rubber frame and the back plate, the middle area of the rubber frame slightly expands outwards, the two side corners of the rubber frame are tightened, and the assembly gap between the rubber frame and the back plate decreases, causing the inner edge of the rubber frame to approach the display area of the liquid crystal display module. The inner edge of the rubber frame will block some of the light emitted by the backlight module, resulting in a reduction in the viewing angle of the liquid crystal display module. Since the red sub-pixels, green sub-pixels, and blue sub-pixels in the liquid crystal display module are arranged horizontally, when the viewing angle of the liquid crystal display module decreases, when observing the left and right edges of the display area of the liquid crystal display module at a certain distance and viewing angle, the difference in the light incident amount of the red sub-pixels, green sub-pixels, and blue sub-pixels will cause uneven color mixing at the left and right edges of the display area, resulting in the problem of visual color deviation, which is particularly serious at the upper and lower corners of the left and right sides of the display area.

[0004] Therefore, it is necessary to provide a liquid crystal display module to improve this defect. Summary of the Utility Model

[0005] An embodiment of the present application provides a liquid crystal display module, which can improve the problem of color deviation while increasing the viewing angle.

[0035] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a 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 those skilled in the art without creative efforts belong to the protection scope of the present application.

[0036] The present application provides a liquid crystal display module. The liquid crystal display module includes a display panel and a backlight module. The display panel is disposed on the light-emitting side of the backlight module. The backlight module includes a frame and a back plate. The frame includes a top frame and a plurality of side frames. The plurality of side frames extend from the four peripheral edges of the top frame in a direction away from the display panel. The display panel is disposed on the top frame. The back plate includes a bottom plate and side plates. The side plates extend from the four peripheral edges of the bottom plate in a direction towards the display panel. The top frame is disposed at one end of the side plates away from the bottom plate. The inner surface of the side frame is disposed opposite to the outer surface of the side plate. At least a part of one side frame adjacent to the other side frame abuts against the side plate, and the other part of the side frame is spaced apart from the side plate.

[0037] In this embodiment, by disposing the top frame of the frame at one end of the side plates of the back plate away from the bottom plate, making the inner surface of the side frame of the frame opposite to the outer surface of the side plate, and making at least a part of one side frame adjacent to the other side frame abut against the side plate, the gap between the corners of the frame and the back plate is kept unchanged, avoiding the inner edge of the frame approaching the display area of the display panel, so that light at a large angle is emitted from the corners on both sides of the display panel. Thus, while maintaining the viewing angle of the display panel unchanged, the problem of color deviation at the corners on both sides of the display panel is improved.

[0038] Combined with Figure 1 and Figure 2 as shown in Figure 1The bottom view of the first liquid crystal display module provided by the embodiments of the present application Figure 2 is Figure 1 a cross-sectional view taken along the direction of A-A' shown in the figure. The liquid crystal display module 100 includes a display panel 1 and a backlight module 2, and the display panel 1 is disposed on the light-emitting side of the backlight module 2.

[0039] As Figure 1 and Figure 2 shown, in this embodiment, the display panel 1 is a liquid crystal display panel, and the display panel 1 includes an array substrate 11, a counter substrate 12, a liquid crystal layer (not shown in the figure), an upper polarizer 13, a lower polarizer 14, and a sealant 15. The array substrate 11 and the counter substrate 12 are disposed opposite to each other, and the counter substrate 12 can be a color filter substrate. The liquid crystal layer is disposed between the array substrate 11 and the counter substrate 12, the upper polarizer 13 is disposed on the side of the counter substrate 12 away from the array substrate 11, and the lower polarizer 14 is disposed on the side of the array substrate 11 away from the counter substrate 12. The sealant 15 is disposed between the edges of the array substrate 11 and the counter substrate 12, and the sealant 15 is used to bond the array substrate 11 and the counter substrate 12 and seal the liquid crystal layer between the array substrate 11 and the counter substrate 12.

[0040] In practical applications, the structure of the display panel 1 is not limited to Figure 1 the structure shown in the figure, and it can also be replaced with the structure of other known liquid crystal display panels.

[0041] As Figure 2 shown, the backlight module 2 includes a frame 21 and a backplane 22. The frame 21 includes a top frame 211 and a plurality of side frames 212. The plurality of side frames 212 are formed by extending from the four peripheral edges of the top frame 211 in a direction away from the display panel 1, and the display panel 1 is disposed on the top frame 211.

[0042] Combined with Figure 1 and Figure 2 shown, the top frame 211 is a ring structure, and the middle part of the top frame 211 is hollowed out. The hollowed-out area in the middle of the top frame 211 is used to transmit the light emitted by the backlight module 2. The top frame 211 is disposed parallel to the display panel 1, and the display panel 1 is disposed on the upper surface of the top frame 211. The plurality of side frames 212 are arranged along the four peripheral edges of the top frame 211, and the side frames 212 are formed by extending from the outer edge of the top frame 211 in a direction away from the display panel 1. An angle is formed between the side frame 212 and the top frame 211. For example, the angle between the side frame 212 and the top frame 211 is 90 degrees, that is, the side frame 212 is perpendicular to the top frame 211.

[0043] In some embodiments, as Figure 2As shown, the liquid crystal display module 100 further includes a fixing member 3. The lower surface of the display panel 1 is fixed on the upper surface of the top frame 211 through the fixing member 3, and the fixing member 3 can be a double-sided adhesive.

[0044] As Figure 2 shown, the backplane 22 includes a bottom plate 221 and side plates 222. The side plates 222 are arranged along the four peripheral edges of the bottom plate 221 and extend from the four peripheral edges of the bottom plate 221 towards the display panel 1. A certain angle is formed between the side plates 222 and the bottom plate 221. For example, the angle between the side plates 222 and the bottom plate 221 is 90 degrees, that is, the side plates 222 are perpendicular to the bottom plate 221.

[0045] As Figure 2 shown, the top frame 211 is arranged at one end of the side plate 222 away from the bottom plate 221, and the lower surface of the top frame 211 abuts against the end face of the side plate 222 away from the bottom plate 221. It should be noted that the lower surface of the top frame 211 abutting against the end face of the side plate 222 away from the bottom plate 221 can mean that the lower surface of the top frame 211 is in direct contact with the end face of the side plate 222 away from the bottom plate 221, or it can mean that the lower surface of the top frame 211 is in indirect contact with the end face of the side plate 222 away from the bottom plate 221, and the indirect contact between the lower surface of the top frame 211 and the end face of the side plate 222 away from the bottom plate 221 is fixed by adhesive bonding.

[0046] In some embodiments, as Figure 2 shown, the backlight module 2 further includes a light guide plate 23, a reflective sheet 24, a light source 25 and an optical film 26. The reflective sheet 24 is arranged on the surface of the bottom plate 221 close to the display panel 1, the light guide plate 23 is arranged on the reflective sheet 24, the light source 25 is arranged on at least one side of the light guide plate 23, and the optical film 26 is arranged on the side of the light guide plate 23 close to the display panel 1. The light guide plate 23, the reflective sheet 24, the light source 25 and the optical film 26 are all arranged in the accommodation space formed by the bottom plate 221 and the side plates 222.

[0047] In some embodiments, as Figure 2 shown, the optical film 26 includes a diffusion sheet 261, a prism sheet 262 and a brightness enhancement film 263 stacked together. In practical applications, the composition of the optical film 26 is not limited to the above embodiments and may also include other optical films.

[0048] In this embodiment, combining Figure 1 and Figure 2As shown, the inner surface of the side frame 212 is disposed opposite to the outer surface of the side plate 222. It should be noted that the inner surface of the side frame 212 refers to the surface of the side frame 212 close to the side plate 222, and the outer surface of the side plate 222 refers to the surface of the side plate 222 close to the side frame 212. The inner surface of the side frame 212 being disposed opposite to the outer surface of the side plate 222 means that the inner surface of the side frame 212 and the outer surface of the side plate 222 face each other.

[0049] In this embodiment, with reference to Figure 1 and Figure 2 As shown, the frame body 21 includes four side frames 212. The four side frames 212 are respectively disposed on the upper and lower sides and the left and right sides of the top frame 211. At least a part of one side frame 212 close to an adjacent side frame 212 abuts against the side plate 222, and the other parts of the side frame 212 are spaced apart from the side plate 222.

[0050] It should be noted that at least a part of one side frame 212 close to an adjacent side frame 212 abutting against the side plate 222 and the other parts of the side frame 212 being spaced apart from the side plate 222 means that the inner surface of at least a part of one side frame 212 close to an adjacent side frame 212 is in contact with the outer surface of the side plate 222, and there is a certain gap between the inner surface of the other parts of this side frame 212 and the outer surface of the side plate 222. In this way, the gap between at least a part of this side frame 212 close to an adjacent side frame 212 and the side plate 222 can be kept unchanged, avoiding the situation that the inner edge of the part of the side frame 212 close to the adjacent side frame approaches the display area and causes the viewing angle to decrease, so that the color deviation at both side corners of the display panel can be improved while maintaining the viewing angle of the liquid crystal display module unchanged.

[0051] In some embodiments, with reference to Figure 1 and Figure 2 As shown, the display panel includes a plurality of red sub-pixels 101, green sub-pixels 102, and blue sub-pixels 103. The red sub-pixels 101, green sub-pixels 102, and blue sub-pixels 103 are alternately and repeatedly arranged along the first direction X, and the first direction X is different from the second direction Y.

[0052] In this embodiment, the first direction X is horizontal, the second direction Y is vertical, the first direction X is perpendicular to the second direction Y, the third direction Z is the thickness direction of the liquid crystal display module, and the side frames 212 of the frame body 21 and the side plates 222 of the back plate 22 both extend along the third direction Z.

[0053] With reference to Figure 1 and Figure 2As shown, a plurality of side frames 212 include two first side frames 2121 and two second side frames 2122. The first side frames 2121 extend along the second direction Y, and the second side frames 2122 extend along the first direction X. The two first side frames 2121 are spaced apart and opposite to each other along the first direction X, and the two second side frames 2122 are spaced apart and opposite to each other along the second direction Y. The first side frames 2121 are connected between the two second side frames 2122.

[0054] In this embodiment, the first side frames 2121 and the second side frames 2122 are integral parts, that is, the first side frames 2121 and the second side frames 2122 can be integrally formed by injection molding. In some other embodiments, the first side frames 2121 and the second side frames 2122 can also be separate parts, and the first side frames 2121 and the second side frames 2122 can be assembled and connected by snap fasteners or other means.

[0055] In this embodiment, in combination with Figure 1 and Figure 2 as shown, the display panel 1 includes a display area AA and a non-display area NA disposed outside the display area AA. The distance between the inner edge of the frame 21 and the edge of the display area AA is d, and the viewing angle of the edge of the display area AA of the display panel 1 is α.

[0056] It should be noted that currently, due to the weak rigidity of the middle area of the rubber frame, the distance between the rubber frame at the upper and lower corners on the left and right sides of the liquid crystal display module and the backplane is reduced, resulting in a reduction in the distance d between the inner edge of the rubber frame and the edge of the display area AA, and a reduction in the viewing angle α of the display panel. Since the red sub-pixels 101, green sub-pixels 102, and blue sub-pixels 103 on the left edge of the display panel are arranged alternately and repeatedly in the horizontal direction from the outside to the inside, at a certain distance and viewing angle, due to the color mixing of the green sub-pixels 102 and blue sub-pixels 103 on the left edge of the display panel, the right edge of the display panel shows cyan. Similarly, the red sub-pixels 101, green sub-pixels 102, and blue sub-pixels 103 on the right edge of the display panel are arranged in the horizontal direction from the inside to the outside. At a certain distance and viewing angle, due to the color mixing of the red sub-pixels 101 and green sub-pixels 102 on the right edge of the display panel, the left edge of the display panel shows yellow, ultimately causing the problem of color deviation on the left and right edges of the display panel, which is particularly serious at the upper and lower corners of the left and right edges of the display panel.

[0057] In combination with Figure 1 and Figure 2As shown, the first side frame 2121 is the side frame on the left and right sides of the display panel 1, and the second side frame 2122 is the side frame on the upper and lower sides of the display panel 1. Currently, color deviation of the display panel mainly occurs in the part of the first side frame 2121 close to the second side frame 2122, that is, at the upper and lower corners on the left and right sides of the display panel 1. In this embodiment, the part of the first side frame 2121 close to the second side frame 2122 abuts against the side plate 222, and the other parts of the first side frame 2121 are spaced from the side plate 222. The whole of the second side frame 2122 is spaced from the corresponding side plate 222. By making the part of the first side frame 2121 close to the second side frame 2122 abut against the side plate 222, it is possible to prevent the distance between the inner edge of the first side frame 2121 and the display area of the display panel 1 from decreasing due to the reduction of the gap between the part of the first side frame 2121 close to the second side frame 2122 and the side plate 222 during assembly. Thus, the problem of color deviation at the upper and lower corners of the left and right edges of the display panel can be improved while maintaining the viewing angle unchanged.

[0058] In some embodiments, the thickness of the part of the first side frame 2121 close to the second side frame 2122 is greater than the thickness of the other parts of the first side frame 2121.

[0059] Combined Figure 1 and Figure 2 As shown, the thickness of the part of the first side frame 2121 close to the second side frame 2122 is the first thickness h1, and the thickness of the other parts of the first side frame 2121 is the second thickness h2. The first thickness h1 is greater than the second thickness h2. By increasing the thickness of the part of the first side frame 2121 close to the second side frame 2122, when the side frame 212 and the back plate 22 are assembled, the part of the first side frame 2121 close to the second side frame 2122 abuts against the side plate 222, and the other parts of the first side frame 2121 are spaced from the side plate 222. Thus, the problem of color deviation at the upper and lower corners of the left and right edges of the display panel can be improved while maintaining the viewing angle unchanged.

[0060] In some embodiments, the first side frame 2121 includes a first side frame main body portion 2121a and a protruding portion 2121b. The protruding portion 2121b is disposed between the part of the first side frame main body portion 2121a close to the second side frame 2122 and the side plate 222.

[0061] Combined Figure 1 and Figure 2As shown, the surface of the first side frame 2121 away from the side plate 222 is a flat surface, and the surface of the first side frame 2121 close to the side plate 222 is an uneven surface. The protruding portion 2121b is disposed between the portion of the first side frame main body 2121a close to the second side frame 2122 and the side plate 222. The surface of the protruding portion 2121b close to the side plate 222 protrudes from the surface of the first side frame main body 2121a close to the side plate 222. In this way, when the frame 21 and the back plate 22 are assembled, the protruding portion 2121b abuts against the side plate 222, and the first side frame main body 2121a is spaced from the side plate 222. Thus, the problem of color deviation at the upper and lower corners of the left and right sides of the display panel can be improved while maintaining the viewing angle unchanged.

[0062] In some embodiments, the first side frame main body 2121a and the protruding portion 2121b are separate parts, and the first side frame main body 2121a and the protruding portion 2121b are assembled and connected. By assembling and connecting the protruding portion 2121b to the first side frame main body 2121a, there is no need to re-open the mold and modify the mold by reducing the glue. Thus, the problem of color deviation of the display panel can be improved while saving the mold cost and time required for re-opening the mold.

[0063] Combined Figure 1 and Figure 2 , the first side frame main body 2121a and the second side frame 2122 are integral parts, that is, the first side frame main body 2121a and the second side frame 2122 are made of the same material, and the first side frame main body 2121a and the second side frame 2122 are integrally formed by injection molding. The protruding portion 2121b and the first side frame main body 2121a are two parts made of different materials, and the protruding portion 2121b is assembled and connected to the first side frame main body 2121a.

[0064] In some embodiments, the first side frame main body 2121a and the protruding portion 2121b are bonded, that is, the first side frame main body 2121a and the protruding portion 2121b are adhered by glue. The surface of the protruding portion 2121b close to the side plate 222 and the outer surface of the side plate 222 can also be adhered by bonding. In this way, the assembly stability of the frame 21 and the back plate 22 can be improved, and the situation where the frame 21 and the back plate 22 are separated due to unstable assembly can be prevented.

[0065] In some embodiments, the material of the first side frame main body 2121a is selected from at least one of polycarbonate, glass fiber, and acrylonitrile-butadiene-styrene copolymer. For example, the material of the first side frame main body 2121a is polycarbonate; or, the material of the first side frame main body 2121a is a mixture of polycarbonate and glass fiber; or, the material of the first side frame main body 2121a is a mixture of polycarbonate and acrylonitrile-butadiene-styrene copolymer.

[0066] In some embodiments, the material of the protrusion 2121b is selected from any one of flexible silicone, rubber, foam, ethylene-vinyl acetate copolymer and polyethylene terephthalate.

[0067] In some embodiments, the first side frame body portion 2121a and the protrusion 2121b are integrally formed.

[0068] Combination Figure 3 and Figure 4 As shown, Figure 3 A bottom view of a second liquid crystal display module provided in an embodiment of the present application, Figure 4 For along Figure 3 The cross-sectional view along the A-A' direction is shown. Figure 3 and Figure 4 The structure of the second liquid crystal display module shown is similar to Figure 1 and Figure 2 The structure of the first type of liquid crystal display module shown is roughly the same, except that: Figure 3 and Figure 4 The first side frame main body 2121a and the protruding part 2121b in the second type of liquid crystal display module shown are an integral part, that is, the first side frame main body 2121a and the protruding part 2121b are made of the same material, and the first side frame main body 2121a and the protruding part 2121b are integrally formed by injection molding. In this way, no additional auxiliary materials are needed, which not only simplifies the assembly process of the liquid crystal display module, but also eliminates the need to reopen the mold and modify the mold to reduce the glue, thereby saving the mold cost and time required for reopening the mold, and improving the color deviation problem of the display panel.

[0069] In some embodiments, the material of the first side frame body 2121a and the protrusion 2121b is selected from at least one of polycarbonate, glass fiber and acrylonitrile-styrene-butadiene copolymer. For example, the material of the first side frame body 2121a and the protrusion 2121b is polycarbonate; or, the material of the first side frame body 2121a and the protrusion 2121b is a mixture of polycarbonate and glass fiber; or, the material of the first side frame body 2121a and the protrusion 2121b is a mixture of polycarbonate and acrylonitrile-styrene-butadiene copolymer.

[0070] In some embodiments, the distance between the inner surface of the first side frame body portion 2121 a and the outer surface of the side plate 222 is equal to the thickness of the protrusion 2121 b.

[0071] Combination Figures 1 to 4As shown, the thickness of the protruding portion 2121b is the third thickness h3, and the third thickness h3 is the difference between the first thickness h1 and the second thickness h2. The distance between the inner surface of the first side frame main body portion 2121a and the outer surface of the side plate 222 is the first distance d1, and the third thickness h3 is equal to the first distance d1. In this way, it can be ensured that after the frame body 21 and the back plate 22 are assembled, the part of the first side frame 2121 close to the second side frame 222 abuts against the side plate 222, so that the problem of color deviation at both corners of the display panel can be improved while maintaining the viewing angle of the display panel unchanged.

[0072] In some embodiments, the thickness of the first side frame main body portion 2121a is greater than or equal to 0.4 mm and less than or equal to 1 mm, and the thickness of the protruding portion is greater than or equal to 0.05 mm and less than or equal to 0.1 mm.

[0073] Combined Figures 1 to 4 As shown, the thickness of the first side frame main body portion 2121a is the first thickness h1, the first thickness h1 is greater than or equal to 0.4 mm and less than or equal to 1 mm, and the thickness of the protruding portion 2121b is the third thickness h3, the third thickness h3 is greater than or equal to 0.05 mm and less than or equal to 0.1 mm. For example, the distance between the inner surface of the first side frame main body portion 2121a and the outer surface of the side plate 222 is the first distance d1, the first distance d1 = 0.1 mm, the first thickness h1 of the first side frame main body portion 2121a = 1 mm, and the third thickness h3 of the protruding portion 2121b = 0.1 mm.

[0074] In some embodiments, the distance between the inner surface of the second side frame 2122 and the outer surface of the side plate 222 is equal to the first distance d1 between the inner surface of the first side frame main body portion 2121a and the outer surface of the side plate 222.

[0076] Advantages of the embodiments of the present application: The embodiments of the present application provide a liquid crystal display module and a display device. The liquid crystal display module includes a display panel and a backlight module. The backlight module includes a frame body and a back plate. By arranging the top frame of the frame body at one end of the side plate of the back plate away from the bottom plate, setting the inner surface of the side frame of the frame body opposite to the outer surface of the side plate, and making at least a part of one side frame adjacent to the other side frame abut against the side plate, the gap between the corner of the frame body and the back plate is kept unchanged, avoiding the inner edge of the frame body from approaching the display area of the display panel, so that light at a large angle is emitted from the two side corners of the display panel. Thus, the problem of color deviation at the two side corners of the display panel can be improved while maintaining the viewing angle of the display panel unchanged.
