[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that, for the sake of convenience of description, only parts related to the present invention rather than all structures are shown in the accompanying drawings.

[0037] An embodiment of the present invention provides a display panel, Figure 1 It is a schematic diagram of a display panel provided by an embodiment of the present invention. Refer to Figure 1 and this display panel includes:

[0038] A plurality of splicing screens 10 and at least two splicing boxes 20;

[0039] At least two splicing screens 10 are arranged on each splicing box 20;

[0040] The edge of the splicing screen 10 located at the edge of the splicing box 20 protrudes outward from the edge of the splicing box 20 in a direction away from the splicing box 20. A splicing block 30 is arranged between two adjacent splicing boxes 20, and the splicing block 30 is in contact with the adjacent splicing boxes 20 respectively.

[0041] Among them, the splicing screen 10 may include a substrate and a plurality of pixel units 11 arranged on the substrate. Each pixel unit 11 may include sub-pixel units of at least three different light-emitting colors. For example, each pixel unit 11 includes a red sub-pixel unit, a green sub-pixel unit, and a blue sub-pixel unit. A driving circuit for driving the pixel unit 11 to emit light may be arranged on the substrate, and the substrate may be a glass substrate or a PCB substrate. The splicing box 20 is used to carry the splicing screen 10. The inside of the splicing box 20 may include a driving circuit board for driving the splicing screen 10 to emit light. The driving circuit board is used to receive an image signal, convert the image signal into a driving signal and send it to the driving circuit of each splicing screen 10, and the driving circuit drives the pixel unit 11 to display a corresponding image.

[0042] Figure 2 is Figure 1 a partial enlarged view of the display panel in Figure 2, the pixel pitch P2 at the seam is mainly composed of three parts (C, D, and E). C is the size of the pixel unit 11 along the first direction X, D is the distance between the pixel unit 11 closest to the boundary on the splicing screen 11 and the boundary of the splicing screen 11 along the first direction X, and E is the seam size between two splicing screens 11 along the first direction X. Among them, the value of E is positive, and there should be no squeezing, otherwise the splicing screen 10 is very likely to be damaged or even broken. The pixel pitch P2 at the seam = C + 2D + E, where the values of C, D, and E are related to the photomask, pixel unit manufacturing process, and large rotation process, etc. The overall accuracy is in the micron level, and the process is stable and generally does not fluctuate. Therefore, the two values that have the greatest impact on P2 are D and E. D is determined by the final edge grinding size accuracy of the splicing screen 11. The current common edge grinding accuracy is ±50μm, and the highest accuracy equipment can currently achieve ±10μm. The value of E is affected by the assembly.

[0043] Figure 3 is a schematic diagram of a splicing process provided by an embodiment of the present invention. Refer to Figure 3 , in this embodiment, the splicing screen 10 located at the edge of the splicing box 20 protrudes outward from the splicing box 20 along the first direction X, that is, a partial area of the splicing screen 10 at the edge of the splicing box 20 is suspended outside the splicing box 20. Since the splicing screen 10 protrudes outward from the splicing box 20 along the first direction X, when two adjacent splicing boxes 20 are spliced, with the same seam size, the distance between the splicing screens 10 at the edges of the adjacent splicing boxes 20 is smaller, making the minimum value of the pixel pitch of the pixel units 11 at the seam smaller. By adjusting the size of the seam, it is easier to make the pixel pitch of the pixel units 11 at the splicing place meet the requirements, that is, it is easier to achieve seamless splicing.

[0044] The display panel according to the embodiment of the present invention makes it easier to achieve seamless splicing of the splicing screen by setting the edge of the splicing screen located at the edge of the splicing box to protrude outward from the edge of the splicing box in the direction away from the splicing box, and a splicing block is arranged between two adjacent splicing boxes. Since the splicing block can better maintain the distance between adjacent splicing boxes, it avoids problems such as damage, breakage, and uneven seams caused by collision and extrusion between the splicing screens of the display panel.

[0045] Optionally, the thickness of the splicing block 30 along the first direction X pointing from one splicing box 20 adjacent to it to another splicing box 20 is determined according to the pixel pitch of the pixel units 11 on the splicing screen 10 along the first direction X, the size of the pixel units 11 on the splicing screen 10 along the first direction X, the distance that the splicing screen 10 at the edge of the splicing box 20 protrudes outward from the splicing box 20 along the first direction X, and the distance between the boundary of the splicing screen 10 at the edge of the splicing box 20 and the pixel unit 11 closest to the boundary.

[0046] Specifically, after each splicing box body 20 is assembled, devices such as a microscope or AOI can be used to measure the distance between the pixel unit 11 closest to the boundary of the splicing screen 10 around the splicing box body 20 and the edge of the splicing screen 10, and the distance that the splicing screen 10 around the splicing box body 20 protrudes from the splicing box body 20. Each splicing box body 20 needs to measure these two distances. Exemplarily, referring to Figure 1 and Figure 3 , the distance D1 between the pixel unit 11 closest to the boundary of the splicing screen 10 in the splicing screen 10 at the edge of the splicing box body 20 on one side of the splicing block 30 and the boundary of the splicing screen 10 can be measured, and the dimension F1 by which the splicing screen 10 at the edge of this splicing box body 20 protrudes from the splicing box body 20 can also be measured. The distance D2 between the pixel unit 11 closest to the boundary of the splicing screen 10 in the splicing screen 10 at the edge of the splicing box body 20 on the other side of the splicing block 30 and the edge of the splicing screen 10 can also be measured, and the dimension F2 by which the splicing screen 10 at the edge of this splicing box body 20 protrudes from the splicing box body 20 can also be measured.

[0047] For two splicing box bodies 20 that are about to be spliced together, since the corresponding C, D1, D2, F1, and F2 values of the splicing box body 20 have been measured, to achieve seamless splicing of the splicing screen 10 between the splicing box bodies 20 and ensure the display quality of the display panel, the pixel pitch P2 at the splicing seam should be evenly transitioned with the pixel pitch P1 in other areas of the display panel or equal to the pixel pitch P1 in other areas of the display panel. As Figure 3 shown, P2 = C + D1 + D2 + G1; where the C value is basically consistent with the design value due to the stable manufacturing process, and the actual values of D1 and D2 have been measured using equipment. To achieve seamless splicing, P2 = C + D1 + D2 + G1 = Pitch, so it is deduced that G1 = Pitch - C - D1 - D2, where Pitch is determined according to the pixel pitch in other areas of the display panel. Exemplarily, Pitch can be equal to the pixel pitch in other areas of the display panel or a value close to the pixel pitch in other areas of the display panel.

[0048] Referring to Figure 1 , a splicing block 3 with a corresponding thickness is selected, and its thickness is H1, such that H1 = G1 + F1 + F2. To achieve seamless splicing, G1 = Pitch - C - D1 - D2, so H1 = Pitch - C - D1 - D2 + F1 + F2; for each pair of splicing box bodies 20 to be spliced together, it is possible to calculate how thick a splicing block 30 needs to be inserted between the two splicing box bodies 20 to perfectly achieve seamless splicing of the splicing screen 10 between the splicing box bodies 20.

[0049] In the display panel of this embodiment, by setting the edge of the splicing screen 10 located at the edge of the splicing box 20 to protrude outward from the edge of the splicing box 20 in a direction away from the splicing box 20, seamless splicing of the splicing screens 10 can be more easily achieved. A splicing block 30 is provided between two adjacent splicing boxes 20. By setting the thickness of the splicing block 30 along the first direction X to be determined according to the pixel pitch of the pixel units 11 on the splicing screen 10 along the first direction X, the size of the pixel units 11 on the splicing screen 10 along the first direction X, the distance that the splicing screen 10 at the edge of the splicing box 20 protrudes outward from the splicing box 20 along the first direction X, and the distance between the boundary of the splicing screen 10 at the edge of the splicing box 20 and the pixel unit 11 closest to the boundary, that is, the thickness of the splicing block 30 is set according to the specific sizes of the splicing screen 10 and the splicing box 20 and the pitch of the pixel units, etc. While achieving seamless splicing between the splicing screens 10, since the splicing block 30 can better maintain the distance between adjacent splicing boxes 20, problems such as damage, breakage, and uneven seams caused by collision and extrusion between the splicing screens in the display panel are avoided.

[0050] Optionally, referring to Figures 1 - 3 , the pixel pitches of the pixel units 11 on the splicing screen 10 along the first direction X are equal; H1 = P1 - C - D1 - D2 + F1 + F2, where H1 is the thickness of the splicing block along the first direction X, P1 is the pixel pitch P1 of the pixel units 11 on the splicing screen 10 along the first direction, C is the size of the pixel units 11 on the splicing screen 10 along the first direction C, D1 is the distance between the boundary of the splicing screen 10 at the edge of the splicing box 20 on the first side of the splicing block 30 and the pixel unit 11 closest to the boundary on this splicing screen 10, D2 is the distance between the boundary of the splicing screen 10 at the edge of the splicing box 20 on the second side of the splicing block 30 and the pixel unit 11 closest to the boundary on this splicing screen 10, F1 is the distance that the splicing screen 10 at the edge of the splicing box 20 on the first side of the splicing block 30 protrudes outward from the splicing box 20 along the first direction X, and F2 is the distance that the splicing screen 10 at the edge of the splicing box 20 on the second side of the splicing block 30 protrudes outward from the splicing box 20 along the first direction X.

[0051] Specifically, the equal pixel pitches of the pixel units 11 on the splicing screen 10 along the first direction X reduce the manufacturing difficulty of the splicing screen 10. Setting H1 = P1 - C - D1 - D2 + F1 + F2 makes the pitch of the pixel units 11 at the seam equal to the pitch of the pixel units in other areas of the display panel, achieving seamless splicing.

[0052] Figure 4 It is a partial enlarged view of the seam of another display panel provided by an embodiment of the present invention. Optionally, referring to Figure 1 and Figure 4, along the direction from the splicing box body 20 to the splicing block 30, the pixel pitch of the pixel units 11 in the splicing screen 10 located at the edge of the splicing box body 20 gradually increases in the first direction X; H1 = P1’ - C - D1 - D2 + F1 + F2, where H1 is the thickness of the splicing block 30 in the first direction X, P1’ is determined according to the pixel pitch of the pixel units 11 in the splicing screen 10 on the edge of the splicing box body 20 in the first direction X, C is the size of the pixel units 11 in the splicing screen 10 in the first direction X, D1 is the distance between the boundary of the splicing screen 10 at the edge of the splicing box body 20 on the first side of the splicing block 30 and the pixel unit 10 closest to the boundary on this splicing screen 10, D2 is the distance between the boundary of the splicing screen 10 at the edge of the splicing box body 20 on the second side of the splicing block 30 and the pixel unit 11 closest to the boundary on this splicing screen 10, F1 is the distance that the splicing screen 10 at the edge of the splicing box body 20 on the first side of the splicing block 30 protrudes from the splicing box body 20 in the first direction X, and F2 is the distance that the splicing screen 10 at the edge of the splicing box body 20 on the second side of the splicing block 30 protrudes from the splicing box body 20 in the first direction X.

[0053] Specifically, in order to avoid sudden changes in pixel pitch at the seam in the existing display panel, the pixel pitch of the pixel units 11 in the splicing screen 10 located at the edge of the splicing box body 20 gradually increases in the first direction X along the direction from the splicing box body 20 to the splicing block 30, that is, along the direction from the splicing screen 10 to the seam, the pitch of the pixel units 11 on the splicing screen 10 gradually increases. For example, referring to Figure 4 , the pixel pitch P4 of the splicing screen 10 is greater than P3. In this embodiment, H1 = P1’ - C - D1 - D2 + F1 + F2 is set, so that the display pitch at the seam and the pixel pitch of the splicing screen 10 are evenly transitioned, improving the display effect. The specific value of P1’ can be set according to the transition requirements. For example, P1’ = P4 or P1’ = P3 can be set.

[0054] Optionally, the splicing block 30 includes alloy steel sheets.

[0055] Specifically, the alloy steel sheets have a relatively high hardness and high dimensional processing accuracy. Setting the splicing block 30 to use alloy steel sheets can, on the one hand, ensure that the splicing block 30 has a high dimensional accuracy, and on the other hand, can prevent the splicing block 30 from deforming due to extrusion during the splicing of the splicing box body 20, affecting the size of the seam.

[0056] It should be noted that this embodiment only exemplarily shows that the splicing block uses alloy steel sheets, which is not a limitation of the present invention. In other embodiments, the splicing block can also use other metal materials with relatively high hardness and high processing accuracy, such as iron.

[0057] Figure 5 is a schematic diagram of another display panel provided by an embodiment of the present invention. Optionally, referring to Figure 5, the display panel further includes:

[0058] A spring lock 40 is disposed between adjacent splicing boxes 20 for locking adjacent splicing boxes 20.

[0059] In this embodiment, the distance between adjacent splicing boxes 20 is maintained by the splicing blocks 30, and the adjacent two splicing boxes 20 are locked by the spring locks 40 to achieve precise seamless splicing control. Two spring locks 40 can be provided between adjacent two splicing boxes 40 to better fix adjacent two splicing boxes 20. The positional relationship between the spring lock 40 and the splicing block 30 can be set as needed, as long as it is ensured that the splicing block 30 can maintain the distance between adjacent two splicing boxes 20 and the spring lock 40 can lock adjacent two splicing boxes 20. Exemplarily, along the extending direction of the opposite faces of adjacent splicing boxes 20, the two spring locks 40 can be disposed on both sides of the splicing block 30.

[0060] Figure 6 is a top view of a display panel provided by an embodiment of the present invention. Optionally, referring to Figure 6 , at least two splicing blocks 30 are provided between adjacent splicing boxes 20; the at least two splicing blocks 30 are arranged in sequence along the extending direction Y of the opposite faces of adjacent splicing boxes 20.

[0061] With this setting, while better maintaining the distance between adjacent splicing boxes 20, the overall weight of the splicing block 30 can be reduced, and the weight of the display panel can be reduced.

[0062] Optionally, the splicing screen includes a glass substrate and a plurality of pixel units disposed on a side of the glass substrate away from the splicing box, and each pixel unit includes sub-pixel units of at least three different light-emitting colors.

[0063] Specifically, the splicing screen can be a glass-based splicing screen, that is, the splicing screen is prepared by using a glass substrate, and it has characteristics such as high precision, active driving, no screen flicker, not easily deformed by heat, high flatness, and large-scale substrate that are not possessed by a PCB-based splicing screen. Adopting the splicing scheme of this embodiment can effectively achieve precise seamless splicing control on the basis of preventing the glass-based splicing screens from colliding with each other during splicing, and effectively improve the display effect of the large glass-based splicing screen.
