The display screen of an embodiment includes a display structure. As shown in fig. 1 to 3, in one embodiment, the display structure 10 includes a box 100 and a display module 300. The case 100 includes a first end cap 110, a frame 130, and a second end cap 120. The first end cover and the second end cover are both used for being fixedly arranged at a target position, and if the first end cover and the second end cover are both fixedly arranged on a wall. In this embodiment, the display structure may be a front maintenance installation or a rear maintenance installation. Referring to fig. 4, specifically, the front maintenance installation mode is wall-mounted, and front installation holes 101 are formed in both sides of the first end cover 110 and the second end cover 120, which are adjacent to the display module (not shown in fig. 4), so as to implement the front maintenance installation of the display module. In one embodiment, rear mounting holes 102 are formed in the first end cover and the second end cover on the sides away from the display module, so that the display module is maintained and mounted after being maintained.

As shown in fig. 2 and fig. 3, in one embodiment, two ends of the frame are respectively connected to the first end cover and the second end cover, and the first end cover and the second end cover are respectively sleeved on two ends of the frame. In this embodiment, the frame is a rectangular frame structure. In one embodiment, the display module 300 includes a first end module unit 310, a middle module unit 320, and a second end module unit 330. The first end module unit, the middle module unit and the second end module unit are spliced together, so that the first end module unit, the middle module unit and the second end module unit are connected together. The first end module unit 310 abuts against the first abutting surface 111 of the first cover 110 and the second abutting surface 131 of the frame, respectively. The intermediate module unit 320 abuts against the second abutting surface 131. The second end module unit 330 abuts against the second abutting surface and the third abutting surface 121 of the second end cap 120, respectively. The first abutting surface, the second abutting surface and the third abutting surface are located on the same plane, namely the first abutting surface, the second abutting surface and the third abutting surface are coplanar. In one embodiment, the middle module unit 320 includes a plurality of sub-module units 320a spliced to each other, and the abutting surfaces of the splicing positions of the sub-module units are located on the same plane, that is, arranged in a coplanar manner.

In the display structure, the first end cover and the second end cover are respectively sleeved at two ends of the frame, the two ends of the frame are respectively connected with the first end cover and the second end cover, and the first end cover and the second end cover are both used for being installed to a target position, so that the display structure is installed at the target position. Because first butt face, second butt face and third butt face are located the coplanar, first butt face promptly, second butt face and third butt face are in the coplanar, and first end module unit respectively with first butt face and second butt face butt, middle module unit and second butt face butt, second end module unit respectively with second butt face and third butt face butt, because first end module unit, middle module unit and second end module unit splice together, make the display area of display module after the concatenation more level and smooth, improved the display plane degree of display structure promptly. During manufacturing, the first end cover, the second end cover and the frame are mechanically fixed together, and then the first abutting surface, the second abutting surface and the third abutting surface are machined into one surface in a unified mode, so that the first abutting surface, the second abutting surface and the third abutting surface are guaranteed to be located on the same plane. During the concatenation, the concatenation of two adjacent display structure carries out the butt through corresponding first end cover and second end cover, consequently as long as ensure the manufacturing accuracy of first end cover and second end cover can, need not the manufacturing accuracy of the great frame of control size, first end cover, second end cover and frame can be separately the shaping and assemble together, the problem that the manufacturing accuracy of frame is difficult to control has been solved, not only the cost of display structure has been reduced, realize the control of the equipment accuracy of display structure easily moreover.

For the traditional display structure, in order to realize the structural function, the modeling plasticity and the screen body assembly precision of the frame, the frame is firstly molded by an integral die-casting mold and then machined, so that the assembly precision of the display structure unit box body and the screen body is ensured, however, the cost of the display structure is higher, and especially the cost of the frame of the display structure in unit area (per square meter) is higher. The frame of the display structure unit box body with the die-casting structure can limit the size of the display structure unit box body, and the size of the spliced large screen is integral multiple of the size of the display structure unit box body. For some occasions with different installation sizes and integral multiples of the sizes of the unit boxes, only compromise selection can be made, and the use convenience of the display structure is poor. In order to solve the problems of high cost and poor convenience of the conventional display structure, as shown in fig. 4, in one embodiment, the frame 120 is a profile structure. In one embodiment, the first end cap 110 and the second end cap 130 are both die cast. Because first end cover and second end cover cup joint in the both ends of frame respectively, when assembling a plurality of above-mentioned display structure, first end cover and second end cover play the concatenation's of two adjacent display structures benchmark effect, determine the concatenation precision of display structure, because first end cover and second end cover are the die-casting structure again, make the first end cover and the second end cover of display structure have higher assembly precision, ensure that first end cover and second end cover have higher benchmark precision, thereby make the first end cover of two adjacent display structures can accurate concatenation, and the second end cover of two adjacent display structures can accurate concatenation, first end cover and second end cover all can design into the structure that the size is shorter, in order to reduce the manufacturing cost of first end cover and second end cover. Because the frame is the section bar structure, the cost of messenger's frame is lower, and the precision of frame can be less than first end cover and second end cover, and the frame is unsettled when adjacent display element splices, does not play the physical connection effect. Compared with the traditional frame formed by integrally die-casting the film, the frame of the display structure is low in cost and can be spliced with high precision.

In addition, because the length of frame is not restricted, the length of frame is variable promptly, realizes that first end cover and second end cover cup joint respectively on the frame of unidimensional, obtains the display structure of unidimensional, has improved the commonality of first end cover and second end cover, can satisfy different demands simultaneously. Because the same first end cover and the same second end cover can be shared for frames with different sizes, only a die-casting die matched with the first end cover and the second end cover needs to be designed, and the design cost and the manufacturing cost of the display structure are greatly reduced. For the size requirement of different display structures, for example, the size of a single display structure can be more than 1000mm × 250mm, 750mm × 250mm or 500mm × 250mm, only the length of the frame needs to be changed, and other structures can be universal, for example, the first end cover and the second end cover can be universal, so that the requirement of a user can be better met.

Two adjacent display structure of tradition carry out the butt through corresponding frame and assemble, because the horizontal machining length of frame is longer, and the whole planarization of frame is relatively poor, lead to showing the problem that has the light leak phenomenon after the structure concatenation.
