Description

[Technical Field]

[0001] This invention relates to the field of display technology, and in particular to a splicing screen and a splicing display device. [Background Technology]

[0002] Large display screens used in public places are generally composed of multiple displays spliced ​​together, which allows for a larger display area to meet the needs of people viewing from a distance. However, most existing large display screens are flat, which can no longer meet the diverse market demands. [Summary of the Invention]

[0003] In view of this, embodiments of the present invention provide a splicing screen and a splicing display device to enable the splicing screen to achieve more diverse screen forms.

[0004] On one hand, embodiments of the present invention provide a splicing screen, including a display screen, the display screen including two opposing first sides and two opposing second sides, wherein the two opposing first sides are not parallel, and the two opposing second sides have different lengths;

[0005] The splicing screen includes at least two adjacent display screens, and for the two display screens spliced ​​together at the first side, there is an included angle between them.

[0006] On the other hand, embodiments of the present invention provide a splicing display device, including the above-mentioned splicing screen.

[0007] One of the above technical solutions has the following beneficial effects:

[0008] In the splicing screen provided in this embodiment of the invention, the included display screen is an irregularly shaped display screen with two non-parallel first sides. Based on this design, for two display screens that need to be spliced ​​at their first sides, there will be a gap between the first sides of the two display screens in their flat state. When the two display screens are brought close together and spliced ​​at an angle, the resulting screen can exhibit a curved shape that converges upwards or downwards. This allows the splicing screen to have a more flexible and diverse shape design, better matching the current market demand for large display screens. Especially when the splicing screen includes a large number of display screens, the screen shape can have more variations. For example, the splicing screen can present a ring-shaped screen shape, with the upper part of the ring-shaped screen converging inwards. [Attached Image Description]

Detailed Implementation Methods

[0054] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0056] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0057] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0058] This invention provides a video wall, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of a splicing screen provided in an embodiment of the present invention. The splicing screen includes a display screen 1, which includes two opposite first sides 2 and two opposite second sides 3. The two opposite first sides 2 are not parallel, and the two opposite second sides 3 have different lengths.

[0059] A video wall consists of at least two adjacent displays 1. For two displays 1 that are spliced ​​together at the first side 2, there is an included angle A between them, meaning that the two displays 1 that are spliced ​​together at the first side 2 are not on the same plane. It should be noted that when a video wall consists of multiple displays 1, the included angle A between different displays 1 that are spliced ​​together at the first side 2 can be different.

[0060] In the splicing screen provided in this embodiment of the invention, the display screen 1 is an irregularly shaped display screen with two non-parallel first sides 2. Based on this design, such as Figure 2 As shown, Figure 2 for Figure 1The diagram illustrates the transition of two displays 1 from a flat state to a spliced ​​state. For the two displays 1 that need to be spliced ​​at their first edges 2, in their flat state, there is a gap between their first edges 2. When the two displays 1 are brought closer together and spliced ​​at an angle A, the resulting screen can exhibit a curved shape that converges upwards or downwards. This allows for more flexible and diverse design options for the spliced ​​screen, better matching the current market demand for large display screens. Especially when the spliced ​​screen includes a large number of displays 1, the screen shape can be more varied, for example, as... Figure 3 As shown, Figure 3 This is another structural schematic diagram of the splicing screen provided in the embodiment of the present invention. The splicing screen can present a ring-shaped screen shape, and the upper part of the ring screen converges inward.

[0061] It should be noted that the process of at least two displays 1 changing from a tiled state to a spliced ​​state mentioned in the embodiments of the present invention can be a process that exists before the splicing screen leaves the factory, or it can be a process that exists during the application of the splicing screen.

[0062] When the process exists before the splicing screen leaves the factory, in the manufacturing process of the splicing screen, the multiple displays 1 included in the splicing screen need to be laid flat on the platform first. At this time, at least two of the displays 1 are in a flat state. Then, at least two displays 1 are fixed so that the splicing screen presents a fixed screen shape. At this time, the at least two displays 1 have completed the transformation from a flat state to a splicing state.

[0063] It is understood that at least two displays 1 can be fixed by adhesive bonding or by other means, and this application does not limit this.

[0064] When this process pertains to the application of a video wall, it means that the video wall can switch between flat and curved states after leaving the factory. When the video wall is flat, at least two displays 1 in the video wall are in a tiled state; when the video wall is curved, at least two displays 1 in the video wall are in a spliced ​​state; when the video wall switches from flat to curved, at least two displays 1 in the video wall undergo a transition from a tiled state to a spliced ​​state.

[0065] In one feasible implementation, see again Figure 1 and Figure 2 In the case of two parallel second sides 3 in display screen 1, the shape of display screen 1 can be designed as a trapezoid or other more regular shape. This not only reduces the design difficulty of display screen 1, but also makes it easier to control the overall shape of the splicing screen when the splicing screen includes multiple display screens 1.

[0066] In one feasible implementation, such as Figure 4 As shown, Figure 4 This is a schematic diagram of a first virtual axis 4 provided in an embodiment of the present invention. For two display screens 1 spliced ​​together at the first side 2, the first virtual axes 4 of the two display screens 1 intersect. The first virtual axes 4 of the two display screens 1 are located in the same plane, and the first virtual axis 4 of the display screens 1 is perpendicular to the arrangement direction of the two first sides 2.

[0067] It should be noted that, due to the different orientations and positions of the different displays 1 in the splicing screen, the arrangement directions of the two first sides 2 in the different displays 1 are different.

[0068] When display screen 1 is a flat panel display screen, see Figure 4 In display screen 1, the arrangement direction x of the two first edges 2 is parallel to the plane on which display screen 1 is located, and also parallel to the extension direction of the straight line connecting the two endpoints of a second edge 3. For example, when the second edge 3 is a straight edge, the arrangement direction x of the two first edges 2 is parallel to the extension direction of the second edge 3. Furthermore, when the two second edges 3 in display screen 1 are parallel, the arrangement direction x of the two first edges 2 in display screen 1 is parallel to the extension direction of the two second edges 3. Moreover, it should be noted that for two display screens 1 spliced ​​together at the first edge 2, these two display screens 1 are not on the same plane, but the first virtual axis 4 of these two display screens 1 is located on the same plane, thus indicating that the first virtual axis 4 of display screen 1 is not parallel to the plane on which display screen 1 is located.

[0069] Alternatively, when display screen 1 is a curved display screen, such as Figure 5 As shown, Figure 5This is another schematic diagram of the first virtual axis 4 provided in an embodiment of the present invention. For a single display screen 1 in a splicing screen, in the orientation directly opposite the display screen 1, the display screen 1 has an orthographic projection 6 on the first plane 5. The orthographic projection 6 includes a first projection edge 7 corresponding to the first edge 2 and a second projection edge 8 corresponding to the second edge 3. The arrangement direction x of the two first edges 2 in the display screen 1 is parallel to the first plane 5 corresponding to the display screen 1, and also parallel to the extension direction of the straight line connecting the two endpoints of one of the second projection edges 8 in the orthographic projection 6. For example, when the second projection edge 8 is a straight edge, the arrangement direction x of the two first edges 2 is parallel to the extension direction of one of the second projection edges 8. Further, when the two second projection edges 8 of the orthographic projection 6 are parallel, the arrangement direction x of the two first edges 2 in the display screen 1 is parallel to the extension direction of the two second projection edges 8. Furthermore, it should be noted that for the two displays 1 spliced ​​together at the first side 2, the two first planes 5 corresponding to these two displays 1 are not on the same plane, but the first virtual axis 4 of these two displays 1 is on the same plane, thus indicating that the first virtual axis 4 of the display 1 is not parallel to the first plane 5 corresponding to the display 1.

[0070] Based on the above design, the screen formed by the two displays 1 spliced ​​together at the first side 2 will present a curved shape that converges upwards or downwards, thus enabling the splicing screen to have a more flexible and diverse shape design.

[0071] In one feasible implementation, to reduce the design complexity and manufacturing cost of display screen 1, see again... Figure 4 The display screen 1 in the splicing screen can be a flat display screen.

[0072] However, it should be noted that, in combination Figure 3 , Figure 12 and Figure 14 It can be seen that when a splicing screen includes multiple displays 1, even if a single display 1 is a planar structure, the overall screen formed by splicing multiple displays 1 can still present a screen shape that is similar to a sphere or other non-planar, approximately smooth curved surface.

[0073] Alternatively, in another feasible implementation, to further optimize the design of the splicing screen, the screen can be made to present a softer, more rounded curved shape, combined with... Figure 5 ,like Figure 6 As shown, Figure 6 This is another structural schematic diagram of the splicing screen provided in the embodiment of the present invention. The display screen 1 in the embodiment of the present invention can also be a curved display screen.

[0074] In one feasible implementation, see again Figure 1The display screen 1 has a first width d in the arrangement direction x of the two first sides 2, and the first width d of the display screen 1 is gradually changed.

[0075] It should be noted that, see Figure 5 When the display screen 1 is a curved display screen, in conjunction with the above description of the arrangement direction x of the two first sides 2 in the curved display screen, the first width d of the display screen 1 in the arrangement direction x of the two first sides 2 can be understood as the width of the orthographic projection 6 of the display screen 1 on the first plane 5 in the arrangement direction of the two first projection sides 7.

[0076] When the first width d of display screen 1 gradually changes, combined with Figure 2 For two displays 1 that need to be spliced ​​at the first edge 2, the width of the gap between them is also gradually changing when the two displays 1 are laid flat. So when the two displays 1 are spliced ​​close to each other, they can make close contact at the splicing position, avoiding splicing gaps and thus helping to improve the splicing effect.

[0077] Furthermore, see again Figure 1 The two opposing second sides 3 of the display screen 1 include a first sub-side 9 and a second sub-side 10. For the two display screens 1 spliced ​​together at the first side 2, the first width d of the two display screens 1 decreases or increases along the direction from the first sub-side 9 to the second sub-side 10, so as to better make the screen formed by the two display screens 1 present a curved shape that converges upward or downward.

[0078] In one feasible implementation, such as Figure 7 As shown, Figure 7 This is another schematic diagram of a splicing screen provided in an embodiment of the present invention. The splicing screen includes at least four adjacent display screens 1. For any one of the four adjacent display screens 1, display screen 1 is spliced ​​with another display screen 1 at a first side 2 and a second side 3, respectively. Furthermore, any two adjacent display screens 1 have an included angle. Further, for two display screens 1 spliced ​​at the first side 2, the first virtual axes 4 of the two display screens 1 intersect.

[0079] With this configuration, the screen formed by the four adjacent displays 1 tends to present a biaxial curved surface that bends along the first bending axis P1 and the second bending axis P2. Furthermore, the screen formed by any two adjacent displays 1 can converge on one side, further expanding the flexibility of the splicing screen's shape design. For example, when the splicing screen includes multiple displays 1, it can present a shape such as... Figure 12 The hemispherical or semi-ellipsoidal display shown, or presented as... Figure 14The spherical or ellipsoidal display shown. Especially when the first width d of the display screen 1 gradually changes, the four adjacent display screens 1 can still make close contact with each other without gaps, avoiding cracks or wrinkles in the splicing screen.

[0080] When the video wall includes at least four adjacent displays 1 as described above, in one feasible implementation, such as Figure 8 and Figure 9 As shown, Figure 8 This is a schematic diagram of another structure of the splicing screen provided in an embodiment of the present invention. Figure 9 for Figure 8 The diagram shows four displays 1 in a tiled state. Each display 1 has a first width d along the arrangement direction x of its two first sides 2. The two opposing second sides 3 of the display 1 include a first sub-side 9 and a second sub-side 10. For two displays 1 joined together at the second sides 3, the second sub-side 10 of one display 1 is adjacent to the first sub-side 9 of the other display 1. Furthermore, the first width d of one display 1 increases along the direction from the first sub-side 9 to the second sub-side 10, while the first width d of the other display 1 decreases along the direction from the first sub-side 9 to the second sub-side 10.

[0081] For clarity, Figure 8 and Figure 9 In the figure, the i-th display screen is represented by the figure label 1_i, the first side of the i-th display screen 1_i is represented by the figure label 2_i, the second side of the i-th display screen 1_i is represented by the figure label 3_i, the first sub-side of the i-th display screen 1_i is represented by the figure label 9_i, and the second sub-side of the i-th display screen 1_i is represented by the figure label 10_i, where i takes values ​​of 1, 2, 3, and 4 respectively.

[0082] Based on the above configuration, in four adjacent displays 1, the screen formed by two displays 1 spliced ​​together at the first edge 2 converges upwards, while the screen formed by the other two displays 1 spliced ​​together at the first edge 2 converges downwards. This design allows the spliced ​​screen to achieve... Figure 14 The shape shown is either spherical or ellipsoidal.

[0083] When the video wall includes at least four adjacent displays 1 as described above, in one feasible implementation, such as Figure 10 and Figure 11 As shown, Figure 10 This is a schematic diagram of another structure of the splicing screen provided in an embodiment of the present invention. Figure 11 for Figure 10The diagram shows four displays 1 in a tiled state. Each display 1 has a first width d along the arrangement direction x of its two first sides 2. The two opposing second sides 3 of each display 1 include a first sub-side 9 and a second sub-side 10. For two displays 1 joined together at the second sides 3, the second sub-side 10 of one display 1 is adjacent to the first sub-side 9 of the other display 1. The first width d of both displays 1 increases or decreases along the direction from the first sub-side 9 to the second sub-side 10. Furthermore, the adjacent first sub-side 9 and second sub-side 10 of the two displays 1 have the same length.

[0084] For clarity, Figure 10 and Figure 11 In the figure, the i-th display screen is represented by the figure label 1_i, the first side of the i-th display screen 1_i is represented by the figure label 2_i, the second side of the i-th display screen 1_i is represented by the figure label 3_i, the first sub-side of the i-th display screen 1_i is represented by the figure label 9_i, and the second sub-side of the i-th display screen 1_i is represented by the figure label 10_i, where i takes values ​​of 1, 2, 3, and 4 respectively.

[0085] Based on the above configuration, in four adjacent displays 1, the screens formed by the two displays 1 joined at the first edge 2 all converge upwards or downwards. This design allows the splicing screen to achieve... Figure 12 The display is a hemispherical or semi-ellipsoidal shape. Moreover, when the lengths of the first sub-side 9 and the second sub-side 10 of the two displays 1 spliced ​​together at the second side 3 are the same, the first width d of the two displays 1 will show a uniform and smooth decreasing or increasing trend. When these four splicing screens are spliced ​​together, there will be no gaps at the joint position, which can effectively improve the display effect of the splicing screen.

[0086] In one feasible implementation, such as Figures 12-15 As shown, Figure 12 This is a schematic diagram of another structure of the splicing screen provided in an embodiment of the present invention. Figure 13 for Figure 12 The diagram shows a plurality of displays 1 in a tiled state. Figure 14 This is a schematic diagram of another structure of the splicing screen provided in an embodiment of the present invention. Figure 15 for Figure 14 The diagram shows a plurality of displays 1 in a tiled state. The splicing screen includes at least one sub-sponging screen 11. The sub-sponging screen 11 includes at least two splicing units 12. The displays 1 in two adjacent splicing units 12 are spliced ​​at the first side 2. The splicing unit 12 includes at least one display 1. There is an included angle between any two adjacent displays 1 in the sub-sponging screen 11.

[0087] Based on the foregoing analysis and the shape design of a single display screen 1 in a video wall, when the video wall includes a large number of display screens 1, the screen shape can have more variations, allowing for more flexible and diverse shape designs. For example, when the splicing unit 12 includes multiple display screens 1, the video wall can present... Figure 12 The screen shape shown is hemispherical or semi-ellipsoidal, or as... Figure 14 The spherical or ellipsoidal screen shape shown indicates that when the splicing unit 12 includes a display screen 1, the splicing screen can present a shape like this. Figure 18 The biaxial curved surface shape shown is narrow at both ends and wide in the middle, or it presents a shape like... Figure 21 The equal-width biaxial curved surface shown is designed to better match the current market demand for large display screens.

[0088] In one feasible implementation, see again Figure 12 and Figure 13 The splicing unit 12 includes at least two displays 1, which are sequentially spliced ​​together at the second side 3. The displays 1 have a first width d in the arrangement direction of the two first sides 2. In the splicing unit 12, the first width d of the multiple displays 1 decreases along the arrangement direction of the multiple displays 1. Furthermore, the sub-sponging screen 11 includes opposing first and second sides. In the at least two splicing units 12 of the sub-sponging screen 11, the first width d of the displays 1 closest to the first side is either the smallest or the largest.

[0089] In this setup method, see Figure 13 In the flat state of the multiple displays 1 included in the splicing screen, in the sub-sponsoring screen 11, each splicing unit 12 has a gradually changing width shape, and the width of different splicing units 12 decreases in the same direction. As a result, there is a gradually changing gap between adjacent splicing units 12, and the width of the gap between different splicing units 12 decreases in the same direction. Thus, when adjacent splicing units 12 are brought close together for splicing, the entire sub-sponsoring screen 11 can exhibit a biaxially curved shape that converges upwards or downwards, making the screen of the sub-sponsoring screen 11 more hemispherical. Furthermore, based on the above design, the splicing units 12 can make close contact, avoiding wrinkles, cracks, and other phenomena that may occur between the splicing units 12 after splicing.

[0090] In one feasible implementation, see again Figure 12 and Figure 14 The sub-spanel 11 includes multiple splicing units 12, and each splicing unit 12 includes multiple displays 1. This allows the splicing screen to present a hemispherical, semi-ellipsoidal, spherical, or ellipsoidal shape, thus optimizing the splicing screen's shape design.

[0091] Furthermore, such as Figure 16 As shown, Figure 16 This is another structural schematic diagram of the splicing screen provided in the embodiment of the present invention. The display screen 1 includes a display area 13 and a binding area 14. For two adjacent display screens 1 in the splicing unit 12, the display area 13 of one display screen 1 is adjacent to the binding area 14 of the other display screen 1.

[0092] This configuration avoids the situation where the binding areas 14 of two adjacent displays 1 in the splicing unit 12 are adjacent, thereby avoiding increasing the width of the invalid area at the splicing point of two adjacent displays 1, weakening the splicing seam, and improving the display effect of the splicing screen.

[0093] like Figure 17 As shown, Figure 17 This is a top view of the display screen 1 provided in an embodiment of the present invention. The display area 13 includes a first signal line 60, which may include data lines, power signal lines, and other signal lines used for the normal operation of driving circuits (such as pixel circuits). Figure 17 The diagram uses the data line (Data) as an example. The bonding area 14 includes pin 61, which is connected to the first signal line 60. Pin 61 is used to transmit the required signal to the first signal line 60. It should be noted that... Figure 17 The connection between pin 61 and the first signal line 60 shown is for illustrative purposes only. In practical applications, the first signal line 60 can be directly connected via... Figure 17 The fan-out line 62 shown is connected to pin 61, or the first signal line 60 can also be indirectly connected to pin 61 through some driving circuit (such as a gating circuit).

[0094] In addition, it should be noted that, Figure 16 , Figure 20 and Figure 23 The illustrated display screen 1 is divided into only two areas: display area 13 and bonding area 14. This is only to more clearly demonstrate the overall design of the bonding area 14 of multiple display screens 1 in the splicing screen. In practical applications, see... Figure 17 The edges of the display area 13 and the first edge 2 of the display screen 1, as well as the second edge 3 of the display screen 1 away from the bonding area 14, can be spaced by a certain border. However, it is understandable that since the border of the bonding area 14 needs to accommodate structures such as the pin 61 and the fan-out line 62, it will be much wider than the borders on other sides of the display area 13. Therefore, the arrangement of the bonding areas 14 of multiple displays 1 in the splicing screen will have a greater impact on the width of the invalid area in the splicing screen.

[0095] In one feasible implementation, such as Figure 18 and Figure 19 As shown, Figure 18This is a schematic diagram of another structure of the splicing screen provided in an embodiment of the present invention. Figure 19 for Figure 18 The diagram shows a plurality of displays 1 in a tiled state. The sub-splicing screen 11 includes two splicing units 12, and the splicing unit 12 includes a plurality of displays 1.

[0096] Taking a splicing screen comprising two sub-sponsoring screens 11 as an example, since the first width d of the multiple displays 1 decreases along the arrangement direction of the multiple displays 1 in the splicing unit 12, therefore, see Figure 19 When the sub-spanel 11 includes two splicing units 12, in the tiled state of multiple displays 1, the widths of the two splicing units 12 in the sub-spanel 11 gradually change and decrease in the same direction. Therefore, when these two splicing units 12 are spliced ​​close to each other, the resulting screen can display... Figure 18 The dual-axis curved surface shape shown is narrow at both ends and wide in the middle, which allows for more flexible and diverse shape designs for the splicing screen.

[0097] Furthermore, such as Figure 20 As shown, Figure 20 This is another structural schematic diagram of the splicing screen provided in the embodiment of the present invention. The display screen 1 includes a display area 13 and a binding area 14. The binding area 14 may be provided with pins for connecting to signal lines, etc. The display areas 13 of the display screens 1 in the two splicing units 12 are adjacent.

[0098] With this configuration, the display areas 13 of the adjacent displays 1 in the two splicing units 12 are adjacent, which can significantly reduce or even eliminate the width of the invalid area at the splicing point of the two splicing units 12, thereby effectively weakening the splicing seam and improving the display effect of the splicing screen.

[0099] In one feasible implementation, such as Figure 21 and Figure 22 As shown, Figure 21 This is a schematic diagram of another structure of the splicing screen provided in an embodiment of the present invention. Figure 22 for Figure 21 The diagram shows a plurality of displays 1 in a tiled state. The splicing screen includes two sub-splicing screens 11, each sub-splicing screen 11 includes a plurality of splicing units 12, and each splicing unit 12 includes a display screen 1.

[0100] In this setup method, see Figure 22 When multiple displays 1 are laid out in a flat configuration, and adjacent sub-display screens 11 are brought close together for splicing, the entire splicing screen can then display [the desired image / image]. Figure 21The image shows a dual-axis curved surface with equal width. For example, when the splicing screen includes a large number of displays 1, the screen formed by the entire splicing screen can also be ring-shaped, so that the splicing screen has a more flexible and diverse shape design.

[0101] Furthermore, in this design, since the splicing unit 12 in the sub-splicing screen 11 only includes one display screen 1, therefore, see Figure 22 Multiple displays 1 in the entire sub-slicing screen 11 can be designed with the same size, which can reduce the design differences between different displays 1 and thus greatly reduce the design difficulty.

[0102] Furthermore, such as Figure 23 As shown, Figure 23 This is another structural schematic diagram of the splicing screen provided in the embodiment of the present invention. The display screen 1 includes a display area 13 and a binding area 14. The binding area 14 may be provided with pins for connecting to signal lines, etc. The display areas 13 of the display screens 1 in the two sub-splicing screens 11 are adjacent.

[0103] With this configuration, the display areas 13 of the adjacent displays 1 in the two sub-splicing screens 11 are adjacent, which can significantly reduce or even eliminate the width of the invalid area at the splicing point of the two sub-splicing screens 11, thereby effectively weakening the splicing seam and improving the display effect of the splicing screen.

[0104] In one feasible implementation, see again Figure 14 and Figure 15 The display screen 1 has a first width d in the arrangement direction of the two first sides 2. The splicing screen includes two sub-sponging screens 11, with a junction L between the two sub-sponging screens 11. One of the two sub-sponging screens 11 is a first sub-sponging screen 50, and the other is a second sub-sponging screen 51. In the first sub-sponging screen 50, the first width d of the multiple display screens 1 in the splicing unit 12 decreases along the direction from the junction to the first sub-sponging screen 50. In the second sub-sponging screen 51, the first width d of the multiple display screens 1 in the splicing unit 12 decreases along the direction from the junction L to the second sub-sponging screen 51. This makes the two sub-sponging screens 11 symmetrical, makes the overall shape of the splicing screen more regular, and optimizes the shape design of the splicing screen.

[0105] Furthermore, in this configuration, the size design of the multiple displays 1 in the first sub-segment 50 can be consistent with the size design of the multiple displays 1 in the second sub-segment 51. For example, see... Figure 15 In the flat state of multiple displays 1, along the arrangement direction of multiple displays 1 in the splicing unit 12, the sizes of two displays 1 in two sub-splicing screens 11 that are equidistant from each other can be designed to be the same to reduce design difficulty.

[0106] In one feasible implementation, see again Figure 1 In at least some of the display screens 1, the first edge 2 of the display screen 1 is a straight edge, so that the first edges 2 of the two display screens 1 can be in contact more closely and there is no gap between the two first edges 2.

[0107] It should be noted that when the two second sides 3 of display screen 1 are parallel, see [reference needed]. Figure 19 It could be that one first side 2 is perpendicular to the second side 3, and the other first side 2 is inclined relative to the second side 3, or, see... Figure 22 Alternatively, both first sides 2 can be inclined relative to the second side 3.

[0108] In one feasible implementation, such as Figure 24 and Figure 25 As shown, Figure 24 This is a schematic diagram of another structure of the splicing screen provided in an embodiment of the present invention. Figure 25 for Figure 24 A schematic diagram of a structure of two corresponding displays 1 in a flat state. In at least some of the displays 1, at least one first edge 2 of the display 1 is a curved edge, which makes the splicing screen more likely to present a smooth curved shape.

[0109] When the first side 2 of the display screen 1 is a curved edge, in this embodiment of the invention, as follows: Figure 26 As shown, Figure 26 This is a schematic diagram of a virtual coordinate axis provided in an embodiment of the present invention. The first side 2 of the display screen 1 can satisfy the gradient curve formula in the virtual coordinate system: The virtual coordinate system is centered on the center of the virtual ellipsoid 15, with the X-axis being a straight line parallel to the maximum cross-section 16 of the virtual ellipsoid 15, and the Y-axis being a straight line parallel to the maximum vertical cross-section 17 of the virtual ellipsoid 15. R1 is the maximum radius of the maximum cross-section 16, R2 is the maximum radius of the maximum vertical cross-section 17, and W is the length of the second side 3 where two adjacent displays 1 in the two sub-splicing screens 11 meet. When both the maximum cross-section 16 and the maximum vertical cross-section 17 are circular, the virtual ellipsoid 15 is spherical. In this way, the splicing screen can more closely approximate an ideal ellipsoidal or spherical curved surface shape.

[0110] In one feasible implementation, see again Figure 1 and Figure 2 In at least some of the displays 1, the two first sides 2 of the displays 1 are symmetrical, which makes the design of the displays 1 in the whole splicing screen relatively easy. For example, for multiple displays 1 that need to be spliced ​​sequentially at the first side 2, the multiple displays 1 can be designed with the same size and shape so that the two adjacent displays 1 can be spliced ​​tightly.

[0111] In one feasible implementation, see again Figure 19 In at least part of the display screen 1, one of the first sides 2 of the display screen 1 is perpendicular to the second side 3. For example, when the display screen 1 is a flat display screen, the shape of the display screen 1 can be a right trapezoid.

[0112] When one of the first edges 2 of the display screen 1 is perpendicular to the second edge 3, the pixels close to the first edge 2 can be aligned at the first edge 2, which can weaken the jagged edges of the display screen 1.

[0113] In one feasible implementation, see again Figure 1 For two displays 1 spliced ​​together at the first side 2, the two displays 1 are symmetrical along the first side 2 at the splicing position, that is, the two displays 1 have the same shape and area, and the screen formed by splicing the two has a better appearance.

[0114] In one feasible implementation, such as Figure 27 and Figure 28 As shown, Figure 27 This is a top view of the display screen 1 provided in an embodiment of the present invention. Figure 28 This is a cross-sectional view of a display screen 1 provided in an embodiment of the present invention. The display screen 1 includes a display area 13 and a bonding area 14, with the bonding area 14 located on the backlight side of the display screen 1. A trace 18 in the display area 13 is electrically connected to a pin 20 in the bonding area 14 via a connecting line 19. The connecting line 19 extends from the light-emitting side of the display screen 1 to the backlight side of the display screen 1. (See also...) Figure 28 The connecting line 19 extends from the light-emitting side of the display screen 1 to the side wall of the display screen 1 and then to the backlight side of the display screen 1.

[0115] In this design, the bonding area 14 of the display screen 1 does not occupy the front space of the display screen 1. When facing the display screen 1, only the display area 13 will be seen and the bonding area 14 will not be seen. This allows the display screen 1 to achieve a borderless design on the front. When multiple display screens 1 are spliced ​​together, the width of the invalid area of ​​the display screen 1 at the splicing position can be further reduced, making the splicing effect tend to present an ideal seamless splicing.

[0116] It should be noted that, in the embodiments of the present invention, the first edge 2 and the second edge 3 both refer to the edges of the portion of the display screen 1 exposed on the light-emitting side. Combined with... Figure 27 When the bonding area 14 is placed on the backlight side of the display screen 1, see Figure 28 If the substrate 21 is not bent, then the first side 2 and the second side 3 form the outer edge of the display screen 1. However, if... Figure 29 As shown, Figure 29In another cross-sectional view of the display screen 1 provided in the embodiment of the present invention, if the bonding area 14 is placed on the backlight side of the display screen 1 by bending the substrate 21, then the first side 2 and the second side 3 of the display screen 1 do not refer to the outer edge of the entire display screen 1.

[0117] In one feasible implementation, combined with Figure 27 ,like Figure 30 As shown, Figure 30 This is another cross-sectional view of the display screen 1 provided in an embodiment of the present invention. The display screen 1 includes a display area 13 and a bonding area 14, with the bonding area 14 located on the backlight side of the display screen 1. The display screen 1 includes a substrate 21, and the traces 18 in the display area 13 are electrically connected to the pins 20 in the bonding area 14 through vias 22 penetrating the substrate 21.

[0118] Similar to the design described above, the bonding area 14 in this design also does not occupy the front space of the display screen 1, thereby further reducing the width of the invalid area at the splicing position of the display screen 1, making its splicing effect closer to an ideal seamless splicing. Moreover, in this configuration, the traces 18 in the display area 13 are directly electrically connected to the pins 20 in the bonding area 14 through the vias 22 penetrating the substrate 21. The traces 18 do not need to use the connecting wires 19 bent to the backlight side of the display screen 1 to connect to the pins 20 in the bonding area 14, thus avoiding the risk of connection breakage due to bending or breaking of the connecting wires 19, and the connection reliability between the traces 18 and the pins 20 is higher.

[0119] Understandably, in order for display screen 1 to display normally, such as Figure 31 As shown, Figure 31 This is a schematic diagram of a display screen 1 provided in an embodiment of the present invention. The display screen 1 includes a plurality of pixel rows 23, and each pixel row includes a plurality of pixels 24. The arrangement direction of the plurality of pixel rows 23 intersects with the arrangement direction of the two first sides 2, and the arrangement direction of the plurality of pixels 24 in the pixel rows 23 is parallel to the arrangement direction of the two first sides 2.

[0120] In this embodiment of the invention, the two opposite first edges 2 of the display screen 1 are not parallel, and at least one first edge 2 is tilted relative to a second edge 3. Taking the gradient of the first width d of the display screen 1 as an example, the smaller the first width d, the fewer pixels can be accommodated in the pixel row 23. In one configuration, see [reference needed]. Figure 31 To accommodate the tilted design of the first side 2, pixels 24 that are not in enough space can be removed directly from pixel row 23.

[0121] However, the inventors discovered during their research that directly removing pixel 24 would cause a significant difference in the width of the blank area between the outermost pixel 24 in different pixel rows 23 and the first edge 2, resulting in obvious jagged steps near the first edge 2, and consequently causing noticeable jagged edges on the display screen 1. Especially when two display screens 1 are spliced ​​together at the first edge 2, the total width of the blank area at the splicing position will also be very large, making the impact on the spliced ​​display even more pronounced.

[0122] To this end, the present invention further adjusts the pixel design in the display screen 1 to effectively improve the edge jaggedness problem of the display screen 1, thereby optimizing the display effect of the entire splicing screen.

[0123] In one feasible implementation, such as Figure 32 As shown, Figure 32 This is another structural schematic diagram of the display screen 1 provided in an embodiment of the present invention. The two opposing first sides 2 in the display screen 1 include a third sub-side 25, and the third sub-side 25 is not perpendicular to the second side 3.

[0124] The display screen 1 includes a pixel group 26, which includes at least two first pixel rows 27 arranged in the direction of the two second sides 3. The first pixel rows 27 include second type pixels 29 and at least two first type pixels 28, with the first type pixels 28 located between the third sub-side 25 and the second type pixels 29.

[0125] The display screen 1 has a first width d in the arrangement direction of the first side 2. The first pixel row 27 in the pixel group 26 includes a first sub-pixel row 30 and a second sub-pixel row 31. The first width d of the display screen 1 at the location of the first sub-pixel row 30 is greater than the first width d at the location of the second sub-pixel row 31. The distance d2 between the geometric center points of the first type of pixels 28 in the second sub-pixel row 31 is less than the distance d1 between the geometric center points of the first type of pixels 28 in the first sub-pixel row 30.

[0126] In this configuration, when the first width d at the location of the second sub-pixel row 31 of the display screen 1 is small, the overall width required by the entire second sub-pixel row 31 in the first side 2 arrangement direction can be compressed by compressing the distance between the geometric center points of the first type of pixels 28 in the second sub-pixel row 31, thereby making the overall width of the second sub-pixel row 31 match the first width d at that location.

[0127] Compared to Figure 31As shown in the method of directly removing the outermost pixel, this setting method can make the width of the blank area between the outermost first type pixel 28 and the third sub-edge 25 in each first pixel row 27 similar and small, thereby avoiding the formation of obvious steps at the third sub-edge 25 and effectively weakening the edge jaggedness of the display screen 1.

[0128] Furthermore, when the width of the blank area between the outermost first type pixel 28 and the third sub-edge 25 in each first pixel row 27 is small, when the two displays 1 are spliced ​​at the third sub-edge 25, the width of the blank area between the two opposite first pixel rows 27 in the two displays 1 will also be small, thus further reducing the area of ​​the invalid area at the splicing position of the two displays 1 and improving the splicing display effect.

[0129] It should be noted that the pixels of the first type 28, second type 29, etc., involved in the embodiments of the present invention can all refer to the smallest light-emitting unit in the display screen 1 used to emit white light. Combined with Figure 38 A pixel may include multiple sub-pixels for emitting different colors of light, such as red, green, and blue sub-pixels, or red, green, blue, and white sub-pixels. Furthermore, the number of sub-pixels included in a pixel is unlimited; for example, a pixel may include one red sub-pixel, one green sub-pixel, and one blue sub-pixel, or it may include one red sub-pixel, one green sub-pixel, and multiple blue sub-pixels.

[0130] In this embodiment of the invention, the display screen 1 can be a liquid crystal display (LCD) screen. For example... Figure 33 As shown, Figure 33 This is another cross-sectional view of the display screen 1 provided in an embodiment of the present invention. The liquid crystal display screen includes an array substrate 70 and a color filter substrate 71 facing each other, and liquid crystal 72 located between the array substrate 70 and the color filter substrate 71. The array substrate 70 may include a driving circuit 73, a pixel electrode 74, and a common electrode 75. The color filter substrate 71 includes a black matrix 76 and a color resist 77. The black matrix 76 has a first opening 78, which defines the light-emitting area of ​​the liquid crystal display screen. Furthermore, the array substrate 71 may also include a first substrate 79 and a plurality of first insulating layers 80, and the color filter substrate 71 may also include a second substrate 81, which will not be described in detail here.

[0131] When the display screen 1 is a liquid crystal display screen, the sub-pixel mentioned above can be regarded as the first opening 78 of the black matrix 76. The shape and area of ​​the sub-pixel and the pixel are all related to the design of the first opening 78. For example, by adjusting the shape of the first opening 78, the shape of the sub-pixel can be adjusted, and then the shape of the entire pixel can be adjusted.

[0132] Alternatively, the display screen 1 in this embodiment of the invention can also be an organic light-emitting diode (OLED) display screen. For example... Figure 34 As shown, Figure 34 This is another cross-sectional view of the display screen 1 provided in an embodiment of the present invention. The organic light-emitting diode (OLED) display screen includes a circuit device layer 82 and a light-emitting device layer 83. The circuit device layer 82 includes pixel circuitry 84, and the light-emitting device layer 83 includes an anode layer 85, a pixel definition layer 86, a light-emitting layer 87, and a cathode layer 88. The pixel definition layer 86 includes a second opening 89 that exposes at least a portion of the anode layer 85 and defines a light-emitting area of ​​the OLED display panel. Furthermore, the circuit device layer 82 may also include a third substrate 90 and a plurality of second insulating layers 91, which will not be described in detail here.

[0133] When the display screen 1 is an organic light-emitting diode display screen, the sub-pixel in this embodiment of the invention can be regarded as the second opening 89 of the pixel definition layer 86. The shape and area of ​​the sub-pixel and the pixel are all related to the design of the second opening 89. For example, by adjusting the shape of the second opening 89, the shape of the sub-pixel can be adjusted, and then the shape of the entire pixel can be adjusted.

[0134] Alternatively, the display screen 1 in this embodiment of the invention can also be a light-emitting diode (LED) display screen. For example... Figure 35 As shown, Figure 35 This is another cross-sectional view of the display screen 1 provided in an embodiment of the present invention. The light-emitting diode display screen includes a driving substrate 92 and light-emitting diodes 93 bonded to the driving substrate 92.

[0135] When the display screen 1 is a light-emitting diode display screen, the sub-pixel in this embodiment of the invention can be regarded as a light-emitting diode 93. The shape and area of ​​the sub-pixel and the pixel are all related to the design of the light-emitting diode 93. For example, by using light-emitting diodes 93 with different shapes, the shape of the sub-pixel can be adjusted, and then the shape of the entire pixel can be adjusted.

[0136] Furthermore, in the embodiments of the present invention, the pixel can be a relatively regular shape such as a polygon, a near polygon, a circle, or a near circle. When the pixel is a polygon or a near polygon, the geometric center point of the pixel is the intersection of the diagonals. When the pixel is a circle or a near circle, the geometric center point of the pixel is the center of the circle.

[0137] In one feasible implementation, see again Figure 32The first width d of the display screen 1 decreases, and along the direction of the decrease of the first width d, the distance between the geometric center points of the first type of pixels 28 in the plurality of first pixel rows 27 in the pixel group 26 also decreases.

[0138] In other words, the smaller the width d, the smaller the distance between the geometric center points of the first type of pixels 28 in the first pixel row 27. This results in a smaller overall width occupied by these first type of pixels 28 along the arrangement direction of the two first sides 2, making the width of the first pixel row 27 more compatible with the tilt direction of the third sub-side 25. Furthermore, the decreasing distance between the geometric center points of the first type of pixels 28 in the multiple first pixel rows 27 in the pixel group 26 allows for a more uniform and smoother arrangement of the first type of pixels 28 in the multiple first pixel rows 27, optimizing the display effect within the area where the first type of pixels 28 are located.

[0139] In one feasible implementation, such as Figure 36 As shown, Figure 36 This is a partial structural diagram of a display screen 1 provided in an embodiment of the present invention. In the first sub-pixel row 30, the distance d1 between the geometric center points of the first type of pixels 28 is less than or equal to the distance d3 between the geometric center points of the second type of pixels 29. In the second sub-pixel row 31, the distance d2 between the geometric center points of the first type of pixels 28 is less than the distance d3 between the geometric center points of the second type of pixels 29.

[0140] For example, when the first sub-pixel row 30 is the first pixel row 27 closest to the second side 3, and the first width d of the display screen 1 at the location of the first sub-pixel row 30 is the largest, the distance d1 between the geometric center points of the first type of pixels 28 in the first sub-pixel row 30 can be equal to the distance d3 between the geometric center points of the second type of pixels 29. At this time, the spacing between the geometric center points of any two adjacent pixels in the first sub-pixel row 30 is equal.

[0141] When there are other first pixel rows 27 between the first sub-pixel row 30 and the second side 3, the distance d1 between the geometric center points of the first type of pixels 28 in the first sub-pixel row 30 can be less than the distance d3 between the geometric center points of the second type of pixels 29, so as to compress the overall width required by the first sub-pixel row 30 in the arrangement direction of the two first sides 2, so as to better match the tilt direction of the third sub-side 25.

[0142] In one feasible implementation, see again Figure 36 The spacing h2 between adjacent first-class pixels 28 in the second sub-pixel row 31 is smaller than the spacing h1 between adjacent first-class pixels 28 in the first sub-pixel row 30.

[0143] This setting method reduces the distance between the geometric center points of adjacent first-class pixels 28 by compressing the distance between adjacent first-class pixels 28 in the second sub-pixel row 31. This eliminates the need to adjust the size of individual first-class pixels 28, keeping the size of the first-class pixels 28 consistent with the size of the second-class pixels 29, avoiding any impact on the light-emitting area of ​​the first-class pixels 28, and ensuring that each individual first-class pixel 28 still has high display brightness.

[0144] In this embodiment of the invention, when the spacing h2 between adjacent first-type pixels 28 in the second sub-pixel row 31 is less than the spacing h1 between adjacent first-type pixels 28 in the first sub-pixel row 30, see again... Figure 36 The spacing h1 between adjacent first-class pixels 28 can be less than or equal to the spacing h3 between adjacent second-class pixels 29. In the second sub-pixel row 31, the spacing h2 between adjacent first-class pixels 28 is less than the spacing h3 between adjacent second-class pixels 29.

[0145] In one feasible implementation, such as Figure 37 As shown, Figure 37 This is a schematic diagram of another partial structure of the display screen 1 provided in an embodiment of the present invention. The first type of pixel 28 has a second width in the arrangement direction of the two first sides 2. The second width k2 of the first type of pixel 28 in the second sub-pixel row 31 is smaller than the second width k1 of the first type of pixel 28 in the first sub-pixel row 30, so that the distance between the geometric center points of adjacent first type of pixel 28 in the second sub-pixel row 31 is smaller than the distance between the geometric center points of adjacent first type of pixel 28 in the first sub-pixel row 30.

[0146] In this embodiment of the invention, when the second width k2 of the first type of pixel 28 in the second sub-pixel row 31 is less than the second width k1 of the first type of pixel 28 in the first sub-pixel row 30, the second width k1 of the first type of pixel 28 in the first sub-pixel row 30 may be less than or equal to the second width k3 of the second type of pixel 29, and the second width k2 of the first type of pixel 28 in the second sub-pixel row 31 may be less than the second width k3 of the second type of pixel 29.

[0147] Furthermore, such as Figure 38 As shown, Figure 38This is a partial structural diagram of the display screen 1 provided in an embodiment of the present invention. The first type of pixel 28 includes a plurality of sub-pixels 32, which are arranged along the arrangement direction of the two first sides 2. In this embodiment of the present invention, the first type of pixel 28 may include a red sub-pixel for emitting red light, a green sub-pixel for emitting green light, and a blue sub-pixel for emitting blue light. The spacing z2 between the sub-pixels 32 of the first type of pixel 28 in the second sub-pixel row 31 is smaller than the spacing z1 between the sub-pixels 32 of the first type of pixel 28 in the first sub-pixel row 30, so as to compress the second width k2 of the first type of pixel 28 in the second sub-pixel row 31.

[0148] Moreover, this setting method reduces the second width k2 of the first type of pixels 28 by compressing the spacing between the sub-pixels 32 of the first type of pixels 28 in the second sub-pixel row 31. This way, it is not necessary to change the size of the individual sub-pixels 32 in this part of the first type of pixels 28, so that the size of the sub-pixels 32 in this part of the first type of pixels 28 is still consistent with the size of the sub-pixels 32 of the same light-emitting color in the second type of pixels 29. This avoids affecting the light-emitting area of ​​this part of the first type of pixels 28 and ensures that the individual first type of pixels 28 still has a high display brightness.

[0149] In one feasible implementation, see again Figure 32 In pixel group 26, the first pixels 33 of multiple first pixel rows 27 are aligned. The first pixel 33 is the first type pixel 28 in the first pixel row 27 that is closest to the second type pixel 29, so that the arrangement of the second type pixel 29 in the first pixel row 27 will not be affected by the arrangement of the first type pixel 28, and the second type pixel 29 in each first pixel row 27 is aligned.

[0150] In one feasible implementation, such as Figure 39 As shown, Figure 39 This is a partial structural diagram of the display screen 1 provided in an embodiment of the present invention. The pixel group 26 includes a first pixel group 34 and a second pixel group 35. The first width of the display screen 1 at the location of the first pixel group 34 is greater than the first width at the location of the second pixel group 35.

[0151] In this group, the number of first-type pixels 28 included in the first pixel row 27 of the first pixel group 34 is equal to the number of first-type pixels 28 included in the first pixel row 27 of the second pixel group 35. The first pixel 33 of the first pixel row 27 of the second pixel group 35 is aligned with the second-type pixels 29 of the first pixel row 27 of the first pixel group 34. The first pixel 33 is the first-type pixel 28 in the first pixel row 27 that is closest to the second-type pixels 29.

[0152] Because the width of the display screen 1 at the location of the second pixel group 35 is relatively small, when the number of first-type pixels 28 included in the first pixel row 27 of the second pixel group 35 is equal to the number of first-type pixels 28 included in the first pixel row 27 of the first pixel group 34, aligning the first pixel 33 of the first pixel row 27 of the second pixel group 35 with the first pixel 33 of the first pixel row 27 of the first pixel group 34 may result in insufficient space in the first pixel row 27 of the second pixel group 35 to accommodate all the first-type pixels 28. Therefore, by aligning the first pixel 33 of the first pixel row 27 of the second pixel group 35 with the second-type pixels 29 of the first pixel row 27 of the first pixel group 34, this embodiment of the invention can provide more space for the first-type pixels 28 near the third sub-side 25, which helps to optimize the arrangement of the first-type pixels 28 in the second pixel group 35.

[0153] In one feasible implementation, such as Figure 40 As shown, Figure 40 This is a partial structural diagram of the display screen 1 provided in an embodiment of the present invention. The pixel group 26 includes a first pixel group 34 and a second pixel group 35. The first width of the display screen 1 at the location of the first pixel group 34 is greater than the first width at the location of the second pixel group 35.

[0154] In this case, the number of first-type pixels 28 included in the first pixel row 27 of the first pixel group 34 is greater than the number of first-type pixels 28 included in the first pixel row 27 of the second pixel group 35. The first pixel 33 of the first pixel row 27 of the first pixel group 34 and the first pixel 33 of the first pixel row 27 of the second pixel group 35 are aligned. The first pixel 33 is the first-type pixel 28 in the first pixel row 27 that is closest to the second-type pixel 29.

[0155] Since the first width of the display screen 1 at the location of the second pixel group 35 is small, the number of first type pixels 28 included in the first pixel row 27 of the second pixel group 35 can be set to be less, so as to provide more adjustment space for the spacing between the geometric center points of the first type pixels 28 in the first pixel row 27 of the second pixel group 35.

[0156] In one feasible implementation, see again Figure 40 The number of first-class pixels 28 located on the same side as second-class pixels 29 in the first pixel row 27 is greater than or equal to 5.

[0157] If the number of first-type pixels 28 in the first pixel row 27 is set too small, the degree of control over the spacing between the geometric center points of the first-type pixels 28 will be relatively limited. Therefore, in this embodiment of the invention, by setting the number of first-type pixels 28 located on the same side of the second-type pixels 29 in the first pixel row 27 to be greater than or equal to 5, the control over the overall width occupied by this part of the first-type pixels 28 can be more flexible.

[0158] In one feasible implementation, such as Figure 41 As shown, Figure 41 This is a partial structural diagram of the display screen 1 provided in an embodiment of the present invention. The first type of pixel 28 includes a first pixel edge 36, which is located on the side closer to the second type of pixel 29. The first type of pixel 28 in the first pixel row 27 includes a first pixel 33 and a second pixel 37. The first pixel 33 is the first type of pixel 28 closest to the second type of pixel 29, and the second pixel 37 is located between the first pixel 33 and the third sub-edge 25. The first width d of the display screen 1 decreases, and the first pixel edge 36 in the second pixel 37 is inclined along the direction closer to the second type of pixel 29 in the direction of the decrease in the first width d.

[0159] After adjusting the spacing between the geometric center points of the first type of pixels 28 in the first pixel row 27, the first type of pixels 28 in the multiple first pixel rows 27 will be arranged non-aligned. By designing the first pixel edge 36 of the second pixel 37 to be tilted, the step between the first pixel edge 36 of the second pixel 37 in the multiple first pixel rows 27 can be weakened, thereby further weakening the jaggedness formed by the first type of pixels 28.

[0160] As mentioned above, when the display screen 1 in the embodiments of the present invention is a liquid crystal display screen, combined with Figure 33 The shape of the first type of pixel 28 can be adjusted by adjusting the shape of the first opening 78 of the black matrix 76. Alternatively, when the display screen 1 in this embodiment is an organic light-emitting diode display screen, combined with... Figure 34 The shape of the first type of pixel 28 can be adjusted by adjusting the shape of the second opening 89 of the pixel definition layer 86. Alternatively, when the display screen 1 in this embodiment is a light-emitting diode display screen, combined with... Figure 35 The shape of the first type of pixel 28 can be adjusted by selecting light-emitting diodes 94 of different shapes.

[0161] Furthermore, see again Figure 41 In pixel group 26, at least two first pixel rows 27 have first pixel edges 36 of second pixels 37 on a straight line to eliminate the steps formed by first pixel edges 36 of second pixels 37 in multiple first pixel rows 27.

[0162] In one feasible implementation, see again Figure 41 The second pixel 37 includes a first type of second pixel 38 and a second type of second pixel 39. The second type of second pixel 39 is located between the first type of second pixel 38 and the first pixel 33. The tilt of the first pixel edge 36 of the second type of second pixel 39 is less than the tilt of the first pixel edge 36 of the first type of second pixel 38.

[0163] The pixel edge of the second type pixel 29 is a straight edge. Since the second type second pixel 39 is closer to the second type pixel 29, the tilt of its first pixel edge 36 can be designed to be smaller, so as to reduce the difference in the extension direction of the edges of the second type second pixel 39 and the second pixel 37.

[0164] Furthermore, see again Figure 41 Along the direction from the third sub-edge 25 to the second type of pixel 29, the inclination of the first pixel edge 36 of the plurality of second pixels 37 in the first pixel row 27 decreases, so that the inclination of the first pixel edge 36 of the plurality of second pixels 37 in the first pixel row 27 is uniformly varied along the direction from the third sub-edge 25 to the second type of pixel 29.

[0165] In one feasible implementation, such as Figure 42 As shown, Figure 42 This is a partial structural diagram of the display screen 1 provided in an embodiment of the present invention. The first type of pixel 28 includes a second pixel edge 40, which is located on the side closer to the third sub-edge 25. The second pixel 37 includes a second edge pixel 41 and a second middle pixel 42. The second edge pixel 41 is close to the third sub-edge 25, and the second middle pixel 42 is located between the second edge pixel 41 and the first pixel 33. The second pixel edge 40 of the second middle pixel 42 and the first pixel 33 is inclined along the direction closer to the second type of pixel 29 in the decreasing direction of the first width d.

[0166] As mentioned earlier, after adjusting the spacing between the geometric center points of the first type of pixels 28 in the first pixel row 27, the first type of pixels 28 in the multiple first pixel rows 27 will be arranged in a non-aligned manner. By designing the second pixel edge 40 of the second middle pixel 42 and the second pixel edge 40 of the first pixel 33 to be tilted, the step between the second pixel edge 40 of the second middle pixel 42 in the multiple first pixel rows 27 and the step between the second pixel edge 40 of the first pixel 33 in the multiple first pixel rows 27 can be weakened, further reducing the jaggedness caused by the non-aligned arrangement of the first type of pixels 28.

[0167] Furthermore, see again Figure 42In pixel group 26, the second pixel edges 40 of at least two second intermediate pixels 42 in first pixel rows 27 are located on a straight line to eliminate the steps between the second pixel edges 40 of the second intermediate pixels 42 in multiple first pixel rows 27, and the second pixel edges 40 of at least two first pixels 33 in first pixel rows 27 are located on a straight line to eliminate the steps between the second pixel edges 40 of the first pixels 33 in multiple first pixel rows 27.

[0168] Furthermore, see again Figure 42 For two adjacent first-class pixels 28 in the arrangement direction of the two first edges 2, the second pixel edge 40 of one first-class pixel 28 is parallel to the first pixel edge 36 of the other first-class pixel 28, so that the spacing between the two adjacent first-class pixels 28 remains equal and the display effect is optimized.

[0169] In one feasible implementation, such as Figure 43 As shown, Figure 43 This is a partial structural diagram of the display screen 1 provided in an embodiment of the present invention. The second pixel edge 40 of the second edge pixel 41 is parallel to the third sub-edge 25, so as to further reduce the step between the second pixel edges 40 of the second edge pixels 41 in the plurality of first pixel rows 27.

[0170] Furthermore, see again Figure 43 In pixel group 26, the second pixel edge 40 of at least two first pixel rows 27 of the second edge pixel 41 lies on a straight line to eliminate the step near the third sub-edge 25.
