First, in the present exemplary embodiment, there is provided a screen assembly, as shown in fig. 1 and 2, including: the display device includes a display panel 10, a frame 20 and a buffer 30. The display panel 10 includes a light-emitting surface, a backlight surface facing away from the light-emitting surface, and a sidewall between the light-emitting surface and the backlight surface, and a concave portion 120 is formed at an edge of the display panel 10 on one side of the light-emitting surface; the frame 20 is disposed around the edge of the display panel 10 and used for fixing the display panel 10; a protrusion 210 is formed on the frame 20 at a position corresponding to the recess 120, and the protrusion 210 is located in the recess 120; the buffer 30 is disposed in the recess 120, and the buffer 30 is located between the display panel 10 and the bezel 20 in a direction toward the periphery of the sidewall.
The screen assembly provided by the present disclosure, the frame 20 is annularly disposed on the edge of the display panel 10, the display panel 10 is fixed, the display panel 10 is formed with the recessed portion 120 at the edge of the light emitting surface side, the protruding portion 210 is formed on the frame 20 at a position corresponding to the recessed portion 120, the protruding portion 210 is located in the recessed portion 120, in the thickness direction of the display panel 10, the assembly between the display panel 10 and the frame 20 is formed, the assembly between the display panel 10 and the frame 20 only in the main body extending direction of the display panel 10 is avoided, thereby the assembly between the display panel 10 and the frame 20 in the main body extending direction and the thickness direction of the display panel 10 is realized, the assembly gap between the frame 20 and the display panel 10 can be reduced, the sealing performance and the strength are improved, and the water resistance and the corrosion resistance of the whole machine are improved. In addition, in the direction toward the periphery of the side wall, the buffer member 30 is disposed between the display panel 10 and the frame 20, so that the buffer and shock absorption effects can be achieved between the display panel 10 and the frame 20, and the service life of the screen assembly is prolonged.
Specifically, the display panel 10 includes a main body portion and an edge portion surrounding the main body portion, at least a part of the edge portion being curved. As shown in fig. 2, the display panel 10 is a curved screen, and the edge portion is curved toward the backlight surface side by a certain radian. As shown in fig. 1, it can be seen that, when the display panel 10 is a curved screen, the side wall of the display panel 10 is an inclined plane, and the bezel 20 is in contact with the side wall of the inclined plane, generally due to the existence of material tolerance, the fit clearance between materials is large, and the sealing performance and the aesthetic property are poor, in the present disclosure, by providing the concave portion 120 on the display panel 10 to be matched with the convex portion 210 on the bezel 20, the assembly clearance between the display panel 10 and the bezel 20 is reduced, and the sealing performance and the aesthetic property are improved; the buffer member 30 is disposed between the display panel 10 and the frame 20, and can reduce the fit clearance between the frame 20 and the display panel 10, improve the sealing performance and the aesthetic property of the frame 20, and simultaneously play a role in buffering and protecting, thereby reducing the risk of screen breaking. In addition, the cooperation between the display panel 10 and the bezel 20 through the increase of the concave portion 120 and the convex portion 210 increases the contact area, so that the sealing performance and the strength of the screen assembly are further improved.
The display panel 10 may be rectangular, and the edge portions of two opposite sides of the display panel may be curved, that is, the display panel 10 is a curved screen with two curved sides; alternatively, the edge portions of the four sides of the display panel 10 are curved, that is, the display panel 10 is a curved screen with curved edges. The corners of the rectangular display panel 10 may be rounded. Of course, the display panel 10 may be in a circular, pentagonal or irregular shape, which is not limited in this disclosure, and the edge portion thereof may be partially curved or the edge portion of all the side edges may be curved.
For example, when the edge portions of the side edges of the display panel 10 are all curved, a continuous annular recess 120 is formed at the edge of the periphery of the display panel 10. Further, a circle of the inner sidewall of the bezel 20 forms a continuous annular protrusion 210, and the annular protrusion 210 is located in the annular recess 120. The buffer 30 is annular, and is disposed on the display panel 10 and located in the recess 120. By forming the continuous annular recess 120 at the edge of the periphery of the display panel 10, the fitting area of the protrusion 210 and the recess 120 can be further increased, so that the contact area is further increased, the sealing performance and strength of the screen assembly are further improved, the assembly gap between the display panel 10 and the frame 20 is further reduced, and the sealing performance and the aesthetic property are improved. In addition, adopt annular bolster 30 to play the buffering guard action between display panel 10 and frame 20, guaranteed that each position all has the buffering effect between frame 20 and the display panel 10, further reduce garrulous screen risk.
For example, when the edge of a part of the side of the display panel 10 is curved and the rest of the side is flat, a continuous annular concave portion 120 may be formed at the edge of a circumference of the display panel 10, a continuous annular convex portion 210 may be formed at a circumference of the inner side wall of the bezel 20, and the annular convex portion 210 may be located in the annular concave portion 120. The recess 120 is formed in a continuous transition at a portion where the edge portion is curved and flat, thereby avoiding a step. The shape of the protruding portion 210 matches with the recessed portion 120, so as to ensure that the protruding portion 210 and the recessed portion 120 can be tightly matched after the display panel 10 is assembled on the frame 20, thereby avoiding a large gap. The shape of the ring-shaped buffer 30 is also matched with the recess 120 to ensure the position between the sidewall of the display panel 10 and the protrusion 210.
Specifically, the sides of the buffer 30 and the protruding portion 210 facing away from the backlight surface and the light-emitting surface are located on the same plane or curved surface. As shown in fig. 1, the edge of the display panel 10 is curved, and after the display panel 10 is assembled with the buffer 30 and the frame 20, the display panel 10, the buffer 30 and the frame 20 are located on the same curved surface on the side away from the backlight surface, so as to ensure the smoothness of the surface of the screen assembly, reduce the assembly gap between the display panel 10 and the frame 20, and improve the sealing performance and the aesthetic performance.
In addition, the edge of the display panel 10 is a plane, after the display panel 10 is assembled with the buffer 30 and the frame 20, one side of the buffer 30 and the protrusion 210 departing from the backlight surface and the light-emitting surface are located on the same plane, after the display panel 10 is assembled with the buffer 30 and the frame 20, one side of the display panel 10 departing from the backlight surface and one side of the buffer 30 and the frame 20 departing from the backlight surface are located on the same horizontal plane, so that the smoothness of the surface of the screen assembly is ensured, the assembling gap between the display panel 10 and the frame 20 can be reduced, and the sealing performance and the attractiveness are improved.
Certainly, the edge of the display panel 10 may be partially curved, and partially flat, after the display panel 10 is assembled with the buffer 30 and the frame 20, the sides of the buffer 30 and the protruding portion 210 departing from the backlight surface and the light-emitting surface are located on the same plane or curved surface, so as to avoid the uneven condition of the assembly positions of the display panel 10, the buffer 30 and the frame 20.
As shown in fig. 1, the display panel 10 includes a glass cover plate 110, and a recess 120 is formed on the glass cover plate 110. When the display panel 10 is a curved display panel 10, since the 3D curved glass cover 110 requires CNC machining and hot bending, the strength of the 3D curved glass cover 110 is greatly reduced compared to the conventional 2.5D curved glass cover 110. The concave part 120 is formed on the glass cover plate 110, meanwhile, the special-shaped structure of the convex part 210 of the frame 20 is matched, and then the buffer member 30 is added at the joint of the display panel 10 and the frame 20, so that the assembly gap between the display panel 10 and the frame 20 is reduced, the sealing performance and the attractiveness are improved, the buffer member 30 plays a role in buffering and protecting between the display panel 10 and the frame 20, and the screen breaking risk is reduced; in addition, the display panel 10 and the bezel 20 have an increased contact area due to the engagement of the protrusion 210 and the recess 120, and the sealing performance and strength of the screen assembly are further improved.
Specifically, the concave portion 120 is a step-shaped recess from the light emitting surface to the backlight surface. As shown in fig. 1, the concave portion 120 is formed on the glass cover plate 110, and the concave portion 120 is step-shaped, i.e., has an L-shaped cross section, and is recessed from the light-emitting surface of the glass cover plate 110 to the backlight surface side. The protruding portion 210 is also in a protruding step shape matching with the recessed portion 120, and the cross section of the buffer member 30 is in a rectangular shape to be assembled with the recessed portion 120 and the protruding portion 210. In addition, the recessed portion 120 and the protruding portion 210 are designed to be matched with each other in a step shape, so that the assembling accuracy and strength of the bezel 20 and the display panel 10 can be ensured, and the sealing performance and strength of the screen assembly can be further improved. Of course, the cross-sectional shapes of the concave portion 120 and the convex portion 210 may also be other shapes, such as arc, triangle, etc., which is not limited by the present disclosure.
The size of the recess 120 can be designed according to the actual size of the screen, so as to ensure that the frame 20 has a sufficient fixing effect on the display panel 10. The width of the buffer 30 may be the same as the width of the protrusion 210 in a direction toward the periphery of the sidewall of the display panel 10, and of course, the width of the buffer 30 may be different from the width of the protrusion 210, which is not limited in the present disclosure. In the thickness direction of the display panel 10, the depth of the concave portion 120 is the same as the thickness of the buffer 30 and the convex portion 210, so as to ensure the flatness of the edge of the light-emitting surface of the display panel 10. The depth of the recess 120 may be 1/3-1/2 of the thickness of the glass cover plate 110, and of course, the depth of the recess 120 may be less than 1/3 of the thickness of the glass cover plate 110 or more than 1/2 of the thickness of the glass cover plate 110, which is not limited by the present disclosure.
As shown in fig. 1, the protrusion 210 extends from the side wall of the bezel 20, the recess 120 is formed by being recessed from the side wall of the glass cover 110, the protrusion 210 is located in the recess 120, the side wall of the glass cover 110 abuts against the side wall of the bezel 20, and the assembly in the main body extension direction and the thickness direction of the display panel 10 is formed. The frame 20 may be a middle frame of the display device, the middle frame includes an installation portion assembled with the display panel 10, and further includes an extension portion extending toward a central portion of a backlight surface of the display panel 10, the extension portion and the installation portion are of an integrated structure, and a joint of the extension portion and the installation portion is bent.
Specifically, the buffer member 30 may be formed of rubber, plastic, or the like, so as to ensure sufficient buffering effect and durability, and avoid problems of discoloration, elastic failure, aging, deformation, and the like, which may occur during long-term use.
Wherein, the buffer member 30 can be fixed in the recess 120 by means of bonding or the like; or, when the buffer member 30 is made of a plastic material, and the frame 20 is made of a metal material, the buffer member 30 can be directly formed on the protruding portion 210 of the frame 20 through an injection molding process, so that the buffer member 30 and the frame 20 form an integrated structure, the assembly of the screen assembly is facilitated, the installation accuracy and the fixing strength of the buffer member 30 can be improved, and the sealing performance and the strength of the screen assembly are further improved.
