[0002] With the improvement of living standards, display devices can be seen everywhere in life. Especially as a carrier for information display, the usage scenarios of display devices are increasing, especially in dark environments, such as in cinemas, projections, etc. Since the backplane of the current splicing structure is assembled by a splicing process, there is a problem of light leakage through the gaps at the splicing points, thus affecting the viewing experience in a dark environment.

[0003] Currently, there are two common ways to solve the light leakage problem at the splicing points of the backplane. One is to apply black glue to the gaps at the splicing points to achieve the effect of blocking light, but this method will leave black glue foreign matters inside the backplane; the other is to open a notch at the splicing point of the backplane and then fill it with a plastic part. However, both of the above methods require labor costs, thus increasing the production cost. Summary of the Utility Model

[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, in conjunction with the drawings, the preferred embodiments of the present utility model will be described in detail.

[0027] Refer to Figures 1 to 3 As shown, it shows an embodiment of the splicing structure and the display screen 1 of the present utility model. The splicing structure includes a backplane 100, and the backplane 100 includes a first backplane 110 and a second backplane 120. The first backplane 110 is provided with a first step 111, and the first step 111 is provided at the edge of one end of the first backplane 110; the second backplane 120 is provided with a second step 121, and the second step 121 is provided at the edge of one end of the second backplane 120; wherein, when assembling the first backplane 110 and the second backplane 120, the first step 111 and the second step 121 are overlapped and fixed.

[0028] Specifically, the backplane 100 refers to a circuit board or a frame that supports other circuit boards, components, and the interconnections between components, and provides power and data signals for the supported components. Therefore, the backplane 100 generally surrounds the structural components such as the liquid crystal panel, the middle frame, and the border of the display device; the backplane 100 includes a first backplane 110 and a second backplane 120. The first backplane 110 and the second backplane 120 are spliced together and surround the outside of the liquid crystal panel. The first backplane 110 includes a first step 111, and the first step 111 is provided at the edge of one end of the first backplane 110. The edge of one side of the first backplane 110 is recessed towards the other side without penetrating the other side, so that the first step 111 is formed at the edge of the first backplane 110; the second backplane 120 includes a second step 121, and the second step 121 is provided at the edge of one end of the second backplane 120. The edge of one side of the second backplane 120 is recessed towards the other side without penetrating the other side, so that the second step 121 is formed at the edge of the second backplane 120; the positions of the first step 111 and the second step 121 are arranged oppositely, that is, when the first step 111 is located above, the second step 121 is located below; when the first step 111 is located below, the second step 121 is located above.

[0029] Wherein, when splicing the first backplane 110 and the second backplane 120, a blank holding structure of the backplane 100 is added to the mold, and the first step 111 of the first backplane 110 and the second step 121 of the second backplane 120 are pressed together through stamping of the mold, so that the first step 111 and the second step 121 are overlapped and fixed to each other.

[0030] In this application, the first step 111 and the second step 121 are respectively provided at the splicing joint of the first backplane 110 and the second backplane 120, and the first step 111 and the second step 121 are overlapped together. The first backplane 110 and the second backplane 120 are fixedly connected through a pressing technology. As a result, due to the overlapping effect of the first step 111 and the second step 121 at the splicing joint of the first backplane 110 and the second backplane 120, the splicing joint of the first backplane 110 and the second backplane 120 will not transmit light and there will be no step difference, thereby realizing that the splicing joint of the backplane 100 will not have a light transmission problem and improving the user experience; at the same time, the splicing method of the backplane 100 is simple, and there is no need to rely on other structural components to solve the light transmission problem, thereby reducing unnecessary production and maintenance costs and lowering the production cost.

[0031] In one embodiment, referring to Figure 3As shown, the first step 111 is provided at one end of the first backplate 110 along the length direction of the first backplate 110, and the second step 121 is provided at one end of the second backplate 120 along the width direction of the second backplate 120. Specifically, the first step 111 is disposed on the first backplate 110 along the length direction of the first backplate 110 and is located at the edge of the first backplate 110 along the length direction of the first backplate 110; the second step 121 is provided at one end of the second backplate 120 along the width direction of the second backplate 120 and is located at the edge of the second backplate 120 along the width direction of the second backplate 120; during splicing, one side of the second backplate 120 along its width direction can overlap on one side of the first backplate 110 along its length direction. Therefore, the second backplate 120 is disposed on the upper side or the lower side of the first backplate 110, and the first backplate 110 and the second backplate 120 are perpendicularly connected, thereby improving the structural stability of the first backplate 110 and the second backplate 120.

[0032] Particularly, in this embodiment, the second step 121 extends from one side to the other side of the second backplate 120 along the width direction of the second backplate 120, and the length of the first step 111 is the same as the length of the second step 121. Therefore, the second step 121 can overlap more closely on the first step 111, thereby further improving the fixing stability of the splicing portion of the first backplate 110 and the second backplate 120 and improving the structural stability of the backplate 100.

[0033] In a specific embodiment, referring to Figure 1 As shown, the thickness of the first step 111 is one-half of the thickness of the first backplate 110. Specifically, when producing the first backplate 110, one side of the first backplate 110 is formed with the first step 111 in a way of removing a part at the splicing portion of the first backplate 110 and the second backplate 120. In this embodiment, the thickness of the first step 111 is set to be one-half of the thickness of the first backplate 110, that is, the thickness of the first step 111 is half of the thickness of the first backplate 110, so that the structural stability of the first step 111 is higher. When stamping the first step 111 and the second step 121 subsequently, the first step 111 is not easily damaged, and the service life of the first backplate 110 is improved.

[0034] In one embodiment, referring to Figure 1As shown, the thickness of the second step 121 is one half of the thickness of the second backplane 120. Specifically, when manufacturing the second backplane 120, at the splicing joint of the first backplane 110 and the second backplane 120, one side of the second backplane 120 is formed with the second step 121 by removing a part. In this embodiment, the thickness of the second step 121 is set to be one half of the thickness of the second backplane 120, that is, the thickness of the second step 121 is half of the thickness of the second backplane 120, so that the structural stability of the second step 121 is higher. When stamping the first step 111 and the second step 121 subsequently, the second step 121 is not easily damaged, and the service life of the second backplane 120 is improved; at the same time, the fit between the first step 111 and the second step 121 is higher.

[0035] In a specific embodiment, referring to Figure 4 As shown, the backplane 100 includes two second backplanes 120 and one first backplane 110, and the two second backplanes 120 are respectively fixedly connected to both ends of the first backplane 110. Specifically, the backplane 100 is disposed around the outer side of the liquid crystal panel. Most of the liquid crystal panels on the market are rectangular. Therefore, one first backplane 110 and two second backplanes 120 are provided, and the two second backplanes 120 are respectively fixedly connected to both ends of the first backplane 110, that is, the first steps 111 are provided at both ends of the first backplane 110, and the second steps 121 of the two second backplanes 120 respectively overlap on the two first steps 111 located at both ends of the first backplane 110, so that no light transmission problem occurs at the two splicing joints of the first backplane 110 and the two second backplanes 120.

[0036] In one embodiment, referring to Figure 3 As shown, the backplane 100 further includes a third backplane 130, and one side of the third backplane 130 is fixedly connected to the first backplane 110 and the second backplane 120. Specifically, the backplane 100 further includes a third backplane 130. The third backplane 130 is located outside the first backplane 110 and the second backplane 120, and one side of the third backplane 130 is fixedly connected to the first backplane 110 and the second backplane 120, that is, one end of the first backplane 110 and the second backplane 120 abuts against and is fixed to the third backplane 130, so that the third backplane 130 protects one side of the first backplane 110 and the second backplane 120, and at the same time further fixes the first backplane 110 and the second backplane 120, and improves the structural stability of the backplane 100.

[0037] In particular, the third backplane 130 in this embodiment is also perpendicularly connected to the first backplane 110 and the second backplane 120 respectively, so as to better enclose the internal structural members of the display device in the internal space by the first backplane 110, the second backplane 120, the third backplane 130 and the liquid crystal panel.

[0038] In one embodiment, referring to Figure 2 As shown, the third backplane 130 includes a convex portion 131, and the convex portion 131 protrudes outward from one side of the third backplane 130 in the direction of the first backplane 110 and the second backplane 120, and the convex portion 131 overlaps one end of the first backplane 110 and the second backplane 120. Specifically, the third backplane 130 abuts against one side of the first backplane 110 and the second backplane 120, and the third backplane 130 is located outside the first backplane 110 and the second backplane 120, and one side of the first backplane 110 and the second backplane 120 is spliced; a convex portion 131 is further provided in the direction of the third backplane 130 towards the first backplane 110 and the second backplane 120, and the convex portion 131 protrudes outward from one side of the third backplane 130 in the direction of the first backplane 110 and the second backplane 120, the convex portion 131 extends along the length direction of the third backplane 130, and the convex portion 131 overlaps one end of the first backplane 110 and the second backplane 120, that is, one end of the first backplane 110 and the second backplane 120 abuts against the lower part of the convex portion 131, so that the convex portion 131 can block the gap after the first backplane 110, the second backplane 120 and the third backplane 130 are fixed, and avoid the problem of light transmission between the third backplane 130, the first backplane 110 and the second backplane 120, thereby further reducing the phenomenon of light transmission of the backplane 100 and further improving the user experience.

[0039] In particular, after the first backplane 110, the second backplane 120 and the third backplane 130 are spliced, they also need to be shaped, welded, powder-coated and baked to form the complete structure of the backplane 100, so that the backplane 100 will not show the phenomenon of light transmission without manual interference.

[0040] In a specific embodiment, referring to Figure 3As shown, the third backplane 130 is disposed outside the first backplane 110 and the second backplane 120 along the circumference of the spliced first backplane 110 and second backplane 120. Specifically, the first backplane 110 and the second backplane 120 are spliced with each other, and the third backplane 130 is arranged to extend along the circumference of the assembly after the first backplane 110 and the second backplane 120 are spliced, and the third backplane 130 is disposed outside the first backplane 110 and the second backplane 120, so as to further fix the first backplane 110 and the second backplane 120, and can protect the first backplane 110 and the second backplane 120, and improve the structural stability of the backplane 100.

[0041] Referring to Figure 4 As shown, the present application further provides a display screen 1, and the display screen 1 includes a splicing structure, and the splicing structure is the splicing structure described in any one of the above. Since the splicing structure is described in detail in the above embodiments, it will not be elaborated here.

[0042] Since the display screen 1 adopts the splicing structure in this embodiment, the light transmission phenomenon at the splicing position of the backplane 100 of the splicing structure is reduced, thereby improving the comfort of the display screen 1, improving the user experience, and reducing the production cost.

[0043] In an embodiment, referring to Figure 4 As shown, the display screen 1 includes two second backplanes 120 and one first backplane 110. The two second backplanes 120 are respectively spliced with both ends of the first backplane 110, and the two splicing positions are respectively located at the upper left corner and the upper right corner of the display screen 1. Specifically, light transmission problems are likely to occur at the upper left corner and the upper right corner of the display screen 1, and due to the viewing angle problem of the user, the light transmission positions of the display screen 1 are easily seen by the user, thereby affecting the user experience. To reduce the light transmission phenomenon of the display screen 1, the display screen 1 includes one first backplane 110 and two second backplanes 120. Both ends of the first backplane 110 are respectively lapped and fixed with the two second backplanes 120, and the two splicing positions at both ends of the two second backplanes 120 and the first backplane 110 are respectively located at the upper left corner and the upper right corner of the display screen 1, thereby avoiding the problem of light transmission at the upper left corner and the upper right corner of the display screen 1, improving the comfort of the display screen 1, and improving the user experience.
