Description

Technical Field

[0001] The embodiments of the present application relate to the field of display technology, and in particular, to a display device. Background Art

[0002] A display device is a common electronic output device that can convert electronic files into graphics. Among them, an LED display device is a display device that uses a light emitting diode (LED) as a light source, including multiple light panels spliced ​​together to increase the display area of ​​the display device. However, when the display device is in a light-emitting state or a non-light-emitting state, the splicing seams between adjacent light panels are obvious, and the display effect of the display device is poor. Utility Model Content

[0003] The embodiment of the present application provides a display device, which can solve the technical problem that when the display device is in a light-emitting state or a non-light-emitting state, the joint seams between adjacent light panels are obvious and the display effect of the display device is poor.

[0004] In a first aspect, an embodiment of the present application provides a display device, comprising a plurality of light panels spliced ​​together, wherein the light panels include:

[0005] substrate;

[0006] A plurality of light-emitting elements are disposed on the substrate, and light-emitting surfaces of the light-emitting elements are away from the substrate;

[0007] The encapsulation layer, at least part of which is located on the side of the light-emitting element away from the substrate; the encapsulation layer is provided with a plurality of first grooves arranged in parallel, and a plurality of second grooves arranged in parallel, and the plurality of first grooves and the plurality of second grooves are arranged crosswise.

[0008] In the display device of the embodiment of the present application, a joint seam is formed between adjacent lamp panels, and a plurality of first grooves and a plurality of second grooves are arranged in parallel on the encapsulation layer. When the plurality of light-emitting elements are in a light-emitting state, the joint seam, the plurality of first grooves and the plurality of second grooves will form bright and dark lines, so that the bright and dark lines formed by the joint seam, the plurality of first grooves and the plurality of second grooves can form a grid together, and the mesh of the grid is at least used for the light-emitting elements to emit light.

[0009] When the light and dark lines formed by the splicing seams, multiple first grooves and multiple second grooves can jointly form a grid, the splicing seams are difficult to distinguish from the first grooves and the second grooves, and the light output of multiple light-emitting elements through the grid is relatively uniform, so that users are usually not affected by the splicing seams between adjacent light panels, thereby reducing the impact of the splicing seams between adjacent light panels on the display effect of the display device and improving the display effect of the display device.

[0010] In some embodiments of the present application, the bottom surface of the first groove is located on a side of the light emitting surface of the light emitting element away from the substrate;

[0011] And / or, the bottom surface of the second groove is located on a side of the light emitting surface of the light emitting element facing away from the substrate.

[0012] In this way, the bottom surface of the first groove is located on the side of the light-emitting surface of the light-emitting element away from the substrate. When the light-emitting element emits light toward the encapsulation layer, the light emitted by the light-emitting element will not be reflected in the first groove, thereby reducing the influence of the first groove on the light-emitting process of the light-emitting element.

[0013] And / or, the bottom surface of the second groove is located on the side of the light-emitting element's light-emitting surface away from the substrate. When the light-emitting element emits light toward the packaging layer, the light emitted by the light-emitting element will not be reflected in the second groove, thereby reducing the impact of the second groove on the light-emitting process of the light-emitting element.

[0014] In some embodiments of the present application, the light board is configured as a square light board; the length direction of the first groove is parallel to the length direction of the square light board, and the length of the first groove is equal to the length of the square light board;

[0015] The length direction of the second groove is parallel to the width direction of the square light board, and the length of the second groove is equal to the width of the square light board.

[0016] With such arrangement, when the plurality of light-emitting elements are in a light-emitting state, the light and dark lines formed by the joint seams, the plurality of first grooves and the plurality of second grooves can together form a grid.

[0017] The length direction of the first groove is parallel to the length direction of the square light board, and the length direction of the second groove is parallel to the width direction of the square light board, so that the light and dark lines formed by the splicing seam, multiple first grooves and multiple second grooves are more similar, and the mesh holes of the grid are rectangular, which further has a certain hiding effect on the splicing seam.

[0018] In some embodiments of the present application, at least one of the first groove and the second groove is configured as one of a square groove, an arc-shaped groove, a U-shaped groove, and a triangular groove.

[0019] In this way, at least one of the first groove and the second groove is configured as a square groove, an arc-shaped groove, a U-shaped groove, or a triangular groove, so that the first groove and the second groove can be formed in the packaging layer by laser engraving or mechanical engraving, making the formation process of the first groove and the second groove more convenient.

[0020] In some embodiments of the present application, the depths of the plurality of first grooves are the same, the depths of the plurality of second grooves are the same, and the depth of the first groove is equal to the depth of the second groove;

[0021] And / or, the widths of the plurality of first grooves are the same, the widths of the plurality of second grooves are the same, and the width of the first groove is equal to the width of the second groove.

[0022] With such a configuration, when the light and dark lines formed by the joint seams, the plurality of first grooves, and the plurality of second grooves can jointly form a grid, by changing the width and depth of the first grooves and the second grooves, the light and dark lines formed by the grid are made closer, thereby further improving the uniformity of the grid, reducing the influence of the grid on the light-emitting process of the light-emitting element, and improving the display effect of the display device.

[0023] In some embodiments of the present application, the first portion of the encapsulation layer is filled between adjacent light-emitting elements, and the second portion of the encapsulation layer covers the light-emitting surface of the light-emitting element;

[0024] The first groove and the second groove are arranged on the surface of the second portion of the encapsulation layer away from the substrate.

[0025] In this arrangement, the first part of the encapsulation layer is filled between adjacent light-emitting elements, and the second part of the encapsulation layer covers the light-emitting surface of the light-emitting element, so that the first part of the encapsulation layer can play a certain supporting and insulating role for the adjacent light-emitting elements, thereby reducing the possibility of displacement or short circuit of the light-emitting elements.

[0026] The first groove and the second groove are arranged on the surface of the second part of the encapsulation layer away from the substrate, so that the first groove and the second groove can be formed in the encapsulation layer by laser engraving or mechanical engraving, making the formation process of the first groove and the second groove more convenient.

[0027] In some embodiments of the present application, a cover plate is also included;

[0028] The cover plate is attached to the surface of the packaging layer facing away from the substrate, the cover plate closes the notch of the first groove, and the cover plate closes the notch of the second groove.

[0029] In this arrangement, the cover plate closes the notch of the first groove, and the cover plate closes the notch of the second groove, so that the cover plate can provide certain support and protection for the structures of the first groove and the second groove, reducing the possibility of dust and other impurities falling into the first groove or the second groove, thereby reducing the influence of dust and other impurities on the bright and dark lines formed by the first groove and the second groove, thereby improving the display effect of the display device.

[0030] In some embodiments of the present application, the plurality of light-emitting elements form a plurality of pixel units, the plurality of pixel units are arranged in a plurality of rows and a plurality of columns, and the pixel unit includes at least one of the light-emitting elements;

[0031] The first groove is located between two adjacent rows of pixel units, and the length direction of the first groove is parallel to the row direction of the pixel units; the second groove is located between two adjacent columns of pixel units, and the length direction of the second groove is parallel to the column direction of the pixel units.

[0032] In this arrangement, the first groove is located between two adjacent rows of pixel units, and the length direction of the first groove is parallel to the row direction of the pixel units; the second groove is located between two adjacent columns of pixel units, and the length direction of the second groove is parallel to the column direction of the pixel units, so that the pixel units can face the mesh of the grid formed by the first groove and the second groove, reducing the interference of the first groove and the second groove on the light-emitting process of the pixel units.

[0033] In some embodiments of the present application, the ratio of the width of the first groove to the distance between two adjacent rows of pixel units is greater than or equal to 0.1 and less than or equal to 0.5;

[0034] And / or, the ratio of the width of the second groove to the distance between two adjacent columns of the pixel units is greater than or equal to 0.1 and less than or equal to 0.5.

[0035] In this way, the ratio of the width of the first groove to the distance between two adjacent rows of pixel units is greater than or equal to 0.1 and less than or equal to 0.5, thereby reducing the influence of the first groove on the light emitting process of two adjacent rows of pixel units.

[0036] The ratio of the width of the second groove to the distance between two adjacent columns of pixel units is greater than or equal to 0.1 and less than or equal to 0.5, thereby reducing the influence of the second groove on the light emitting process of two adjacent columns of pixel units.

[0037] In a second aspect, an embodiment of the present application provides a display device, comprising a plurality of light boards spliced ​​to each other, wherein a splicing seam is formed between adjacent light boards; the light board comprises: a substrate, a plurality of light-emitting elements disposed on the substrate, and a packaging layer;

[0038] The encapsulation layer is located on a side of the light emitting element away from the substrate; the encapsulation layer is provided with a plurality of first grooves arranged in parallel, and a plurality of second grooves arranged in parallel;

[0039] The joint seam, the plurality of first grooves and the plurality of second grooves form a grid, and when the plurality of light-emitting elements are in a light-emitting state, the meshes of the grid are at least used for the light-emitting elements to emit light.

[0061] As described in the background art, in the related art, an LED display device is a display device that uses a light emitting diode (LED) as a light source. Figure 1-Figure 3 The display device includes a plurality of light panels 10 spliced ​​together to increase the display area of ​​the display device. The light panels 10 include a substrate 100 and a plurality of light-emitting elements 200 disposed on the substrate 100. The light-emitting sides of the plurality of light-emitting elements 200 face away from the substrate 100. However, when the display device is in a light-emitting state or a non-light-emitting state, the splicing seams 111 between adjacent light panels 10 will form bright and dark lines. In addition, since the light-emitting sides of the light-emitting elements 200 will not be blocked, the splicing seams 111 between adjacent light panels 10 are more obvious, and the display effect of the display device is poor.

[0062] In view of this, in the display device of the embodiment of the present application, a joint seam is formed between adjacent lamp panels, and a plurality of first grooves arranged in parallel and a plurality of second grooves arranged in parallel are arranged in the encapsulation layer. When the plurality of light-emitting elements are in a light-emitting state or a non-light-emitting state, the joint seam, the plurality of first grooves and the plurality of second grooves will form bright and dark lines, so that the light and dark lines formed by the joint seam, the plurality of first grooves and the plurality of second grooves can form a grid together, and the mesh of the grid is at least used for the light-emitting elements to emit light.

[0063] When the light and dark lines formed by the splicing seams, multiple first grooves and multiple second grooves can jointly form a grid, the splicing seams are difficult to distinguish from the first grooves and the second grooves, and the light output of multiple light-emitting elements through the grid is relatively uniform, so that users are usually not affected by the splicing seams between adjacent light panels, thereby reducing the impact of the splicing seams between adjacent light panels on the display effect of the display device and improving the display effect of the display device.

[0064] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0070] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0071] Reference Figure 4-Figure 6An embodiment of the present application provides a display device, which may include a plurality of light panels 10 spliced ​​to each other to increase the display area of ​​the display device, and a splicing seam 11 is provided between adjacent light panels 10.

[0072] Exemplarily, the light board 10 can be set as a square light board 10. A plurality of square light boards 10 can be arranged in multiple rows and columns, and between two adjacent square light boards 10, the extension direction of the first portion of the seam 11 can be set parallel to the length direction of the square light board 10, and the extension direction of the second portion of the seam 11 can be set parallel to the width direction of the square light board 10.

[0073] It is easy to understand that the shape of the light board 10 can also be set to a triangle or hexagon, and the extension direction of the joint seam 11 can be set parallel to the extension direction of the edge of the light board 10, so that multiple light boards 10 can be spliced ​​to form a complete luminous display area.

[0074] Reference Figure 5-Figure 7 In some possible implementations, the light board 10 may include a substrate 100 and a plurality of light emitting elements 200. The plurality of light emitting elements 200 may be disposed on the substrate 100, and the light emitting surfaces of the light emitting elements 200 may be away from the substrate 100, so that the plurality of light emitting elements 200 may realize image display.

[0075] The light board 10 includes an encapsulation layer 300. The encapsulation layer 300 may be located on the side of the light emitting element 200 away from the substrate 100, so as to provide a certain encapsulation protection for the substrate 100 and the light emitting element 200, and reduce the possibility of the light emitting element 200 contacting with water, oxygen, etc.

[0076] The light board 10 can be formed by a COB packaging process (Chip on Board, referred to as COB). The material of the packaging layer 300 can be set to packaging glue, so that the packaging glue is filled between adjacent light-emitting elements 200, so that the packaging glue can support and connect the adjacent light-emitting elements 200.

[0077] The encapsulation layer 300 may be provided with a plurality of first grooves 310 arranged in parallel, and a plurality of second grooves 320 arranged in parallel. The plurality of first grooves 310 and the plurality of second grooves 320 may be cross-arranged. When the plurality of light-emitting elements 200 are in a light-emitting state, the joint seams 11, the plurality of first grooves 310 and the plurality of second grooves 320 form a grid. The mesh of the grid is at least used for light emission of the light-emitting element 200, so that the light emission of the light-emitting element 200 is more uniform.

[0078] In some possible implementations, the substrate 100 may be configured as a printed circuit board (PCB), and the plurality of light emitting elements 200 may be electrically connected to the substrate 100 , so that the plurality of light emitting elements 200 are driven to emit light through the substrate 100 .

[0079] For example, refer to Figure 5 The multiple light-emitting elements 200 may include several first light-emitting elements 200, several second light-emitting elements 200 and several third light-emitting elements 200. The several first light-emitting elements 200, several second light-emitting elements 200 and several third light-emitting elements 200 may be integrated to form several pixel units 201 to realize image display through the several pixel units 201.

[0080] The first light-emitting element, the second light-emitting element and the third light-emitting element in the same pixel unit 201 can emit light of different colors, and the light emitted by the first light-emitting element, the second light-emitting element and the third light-emitting element in the same pixel unit 201 can converge to form a light beam.

[0081] Each pixel unit 201 may include a first light emitting element 200 , a second light emitting element 200 and a third light emitting element 200 , so that the pixel unit 201 can integrate and merge the light from the first light emitting element 200 , the second light emitting element 200 and the third light emitting element 200 to form light beams of different colors.

[0082] Among the plurality of light emitting elements 200, the first light emitting element 200 can emit a first light, which can be set to a red light. The second light emitting element 200 can emit a second light, which can be set to a green light. The third light emitting element 200 can emit a third light, which can be set to a blue light. The pixel unit 201 can merge the red light, the green light and the blue light to form light beams of different colors.

[0083] Several pixel units 201 may be arranged in multiple rows and columns. The first light emitting element 200, the second light emitting element 200, and the third light emitting element 200 in the same pixel unit 201 may be arranged along the row direction of the pixel unit 201. Alternatively, the first light emitting element 200, the second light emitting element 200, and the third light emitting element 200 in the same pixel unit 201 may be arranged along the column direction of the pixel unit 201.

[0084] Exemplarily, the light board 10 is set as a square light board 10, the row direction of the pixel unit 201 can be set parallel to the length direction of the square light board 10, and the column direction of the pixel unit 201 can be set parallel to the width direction of the square light board 10.

[0085] Alternatively, the row direction of the pixel unit 201 can be set parallel to the width direction of the square light board 10, and the column direction of the pixel unit 201 can be set parallel to the length direction of the square light board 10, so that the splicing seam 11 is located between adjacent pixel units 201, and the splicing seam 11 will not extend into the pixel unit 201, thereby improving the display effect of the display device.

[0086] Alternatively, the row direction of the pixel unit 201 forms an angle with the length direction and the width direction of the square light board 10, and the column direction of the pixel unit 201 forms an angle with the length direction and the width direction of the square light board 10.

[0087] In some possible implementations, the encapsulation layer 300 may include a first portion and a second portion connected to each other. The first portion of the encapsulation layer 300 may be filled between adjacent light-emitting elements 200, so that the adjacent light-emitting elements 200 are supported and protected by the first portion of the encapsulation layer 300, thereby reducing the possibility of the light-emitting elements 200 being offset.

[0088] The second part of the encapsulation layer 300 can cover the light emitting surface of the light emitting element 200 , and the surface of the encapsulation layer 300 away from the substrate 100 can be arranged parallel to the substrate 100 to make the surface of the encapsulation layer 300 away from the substrate 100 smoother and improve the aesthetics of the encapsulation layer 300 .

[0089] Exemplarily, the encapsulation layer 300 can be formed on the surface of the substrate 100 by means of gluing or the like, and the first portion of the encapsulation layer 300 can be filled between adjacent light-emitting elements 200. The first portion of the encapsulation layer 300 plays a certain supporting and insulating role for the adjacent light-emitting elements 200, thereby reducing the possibility of the light-emitting elements 200 being offset or short-circuited.

[0090] The second part of the encapsulation layer 300 covers the light emitting surface of the light emitting element 200, and the first groove 310 and the second groove 320 are set on the surface of the second part of the encapsulation layer 300 facing away from the substrate 100, so that the first groove 310 and the second groove 320 can form a grid together with the splicing seam 11, making the formation process of the first groove 310 and the second groove 320 more convenient.

[0091] Reference Figure 5 and Figure 6 In some possible implementations, the first groove 310 may be located between two adjacent rows of pixel units 201 , and the length direction of the first groove 310 may be parallel to the row direction of the pixel units 201 .

[0092] The first groove 310 will not interfere with the light emitting process of the two adjacent rows of pixel units 201 , thereby reducing the possibility that the light emitted by the two adjacent rows of pixel units 201 will be reflected in the first groove 310 .

[0093] The second trench 320 is located between two adjacent columns of pixel units 201 , and the length direction of the second trench 320 is parallel to the column direction of the pixel units 201 .

[0094] The second groove 320 will not interfere with the light emitting process of two adjacent columns of pixel units 201 , thereby reducing the possibility that the light emitted by two adjacent columns of pixel units 201 will be reflected in the second groove 320 .

[0095] The first groove 310 can be located between two adjacent rows of pixel units 201, and the second groove 320 can be located between two adjacent columns of pixel units 201, so that the pixel units 201 can face the mesh of the grid formed by the first groove 310 and the second groove 320, thereby reducing the interference of the first groove 310 and the second groove 320 on the light emitting process of the pixel units 201.

[0096] In two adjacent rows of pixel units 201, the distance between the first groove 310 and one row of pixel units 201 can be equal to the distance between the first groove 310 and the other row of pixel units 201, so that the first groove 310 can be evenly arranged between the two adjacent rows of pixel units 201, making the grid arrangement more uniform, further improving the display effect of the display device.

[0097] The ratio of the width of the first groove 310 to the distance between two adjacent rows of pixel units 201 can be greater than or equal to 0.1 and less than or equal to 0.5. For example, the ratio of the width of the first groove 310 to the distance between two adjacent rows of pixel units 201 can be set within any ratio range of 0.1-0.2, 0.2-0.3, 0.3-0.4, and 0.4-0.5.

[0098] This arrangement can reduce the possibility that the light emitted by the pixel unit 201 passes through the first groove 310 , thereby reducing the influence of the first groove 310 on the light emission process of the pixel units 201 in two adjacent rows.

[0099] The ratio of the width of the second groove 320 (i.e., W1 in the figure) to the distance between two adjacent columns of pixel units 201 (i.e., W2 in the figure) can be greater than or equal to 0.1 and less than or equal to 0.5. For example, the ratio of the width of the second groove 320 to the distance between two adjacent columns of pixel units 201 can be set within any ratio range of 0.1-0.2, 0.2-0.3, 0.3-0.4, and 0.4-0.5.

[0100] This arrangement can reduce the possibility that the light emitted by the pixel unit 201 passes through the second groove 320 , thereby reducing the influence of the second groove 320 on the light emission process of the pixel units 201 in two adjacent columns.

[0101] It is easy to understand that when the pixel unit 201 is in a light-emitting state or a non-light-emitting state, the splicing seam 11, the multiple first grooves 310 and the multiple second grooves 320 will form light and dark lines. The light and dark lines formed by the splicing seam 11, the multiple first grooves 310 and the multiple second grooves 320 can jointly form a grid, so that the multiple first grooves 310 and the multiple second grooves 320 can play a certain hiding role for the splicing seam 11, and the light output of the pixel unit 201 through the grid is more uniform.

[0102] When the pixel unit 201 is in a light-emitting state, the pixel unit 201 can emit light toward the mesh holes of the grid formed by the first groove 310 and the second groove 320, thereby reducing the influence of the first groove 310 and the second groove 320 on the light-emitting brightness and light-emitting direction of the pixel unit 201, making the light emission of several pixel units 201 more uniform, and improving the display effect of the display device.

[0103] For example, refer to Figure 5-Figure 9 The light board 10 is set as a square light board 10, the row direction of the pixel unit 201 is set parallel to the length direction of the square light board 10, and the column direction of the pixel unit 201 is set parallel to the width direction of the square light board 10.

[0104] The length direction of the first groove 310 can be parallel to the row direction of the pixel unit 201, the length direction of the first groove 310 can be parallel to the length direction of the square light board 10, and the length of the first groove 310 can be equal to the length of the square light board 10, so that the splicing seam 11 can be located between adjacent pixel units 201, the splicing seam 11 will not extend into the pixel unit 201, and the pixel unit 201 is spaced apart from the edge of the square light board 10, thereby improving the display effect of the display device.

[0105] The length direction of the second groove 320 can be parallel to the column direction of the pixel unit 201, the length direction of the second groove 320 can be parallel to the width direction of the square light board 10, and the length of the second groove 320 can be equal to the width of the square light board 10, so that the splicing seam 11 is located between adjacent pixel units 201, and the splicing seam 11 will not extend into the pixel unit 201, thereby improving the display effect of the display device.

[0106] In some possible implementations, the depths of the plurality of first grooves 310 may be set to be the same, the depths of the plurality of second grooves 320 may be set to be the same, and the depth of the first groove 310 may be equal to the depth of the second groove 320 .

[0107] And / or, the widths of the plurality of first trenches 310 may be set to be the same, the widths of the plurality of second trenches 320 may be set to be the same, and the width of the first trench 310 may be equal to the width of the second trench 320 .

[0108] When the light and dark lines formed by the joint seam 11, the plurality of first grooves 310 and the plurality of second grooves 320 can jointly form a grid, the light and dark lines formed by the grid are made closer by changing the width and depth of the first grooves 310 and the second grooves 320, thereby further improving the uniformity of the grid, reducing the influence of the grid on the light-emitting process of the light-emitting element 200, and improving the display effect of the display device.

[0109] It is easy to understand that among the multiple first grooves 310, the depth of some first grooves 310 may be different from the depth of the remaining first grooves 310, so that the depth of the first groove 310 can be changed, so that the first groove 310 is closer to the joint seam 11, thereby improving the display effect of the display device.

[0110] Reference Fig.10 Among the plurality of second grooves 320 , the depth of some second grooves 320 may be different from the depth of the remaining second grooves 320 , thereby changing the depth of the second grooves 320 , making the second grooves 320 closer to the joint seam 11 , and improving the display effect of the display device.

[0111] Among the plurality of first trenches 310 , the width of some of the first trenches 310 may be different from the width of the remaining first trenches 310 . Among the plurality of second trenches 320 , the width of some of the second trenches 320 may be different from the width of the remaining second trenches 320 .

[0112] Exemplarily, the depth of the first trench 310 , the width of the first trench 310 , the depth of the second trench 320 , and the width of the second trench 320 may be determined according to the positions of the first trench 310 and the second trench 320 .

[0113] For example, in the length direction of the square light board 10, a plurality of second grooves 320 are arranged in sequence. In the direction from the middle of the square light board 10 to the edge of the square light board 10, the depth of the second groove 320 and the width of the second groove 320 may gradually increase. Alternatively, from one end to the other end in the length direction of the square light board 10, the depth of the second groove 320 and the width of the second groove 320 may gradually increase.

[0114] In the width direction of the square light board 10, a plurality of first grooves 310 may be arranged in sequence and spaced apart. In the direction from the middle of the square light board 10 to the edge of the square light board 10, the depth and width of the first groove 310 may gradually increase, and the depth of the first groove 310 close to the joint seam 11 may be greater than the depth of the first groove 310 far from the joint seam 11, so that the light and dark lines generated by the first groove 310 are closer to the light and dark lines generated by the joint seam 11.

[0115] Alternatively, the depth of the first groove 310 and the width of the first groove 310 may gradually increase from one end to the other end in the width direction of the square light panel 10, so that the first groove 310 and the second groove 320 are closer to the joint seam 11, thereby making the grid formed by the first groove 310, the second groove 320 and the joint seam 11 more uniform, further improving the display effect of the display device.

[0116] Exemplarily, the bottom surface of the first groove 310 may be located on the side of the light emitting surface of the light emitting element 200 away from the substrate 100. In this way, when the light emitting element 200 emits light toward the encapsulation layer 300, the light emitted by the light emitting element 200 will not be reflected in the first groove 310, thereby reducing the influence of the first groove 310 on the light emitting process of the light emitting element 200.

[0117] And / or, the bottom surface of the second groove 320 may be located on the side of the light emitting surface of the light emitting element 200 away from the substrate 100. When the light emitting element 200 emits light toward the encapsulation layer 300, the light emitted by the light emitting element 200 will not be reflected in the second groove 320, thereby reducing the influence of the second groove 320 on the light emitting process of the light emitting element 200.

[0118] Reference Fig.11 In some possible embodiments, at least one of the first groove 310 and the second groove 320 can be set as one of a square groove, an arc-shaped groove, a U-shaped groove, and a triangular groove, so that the first groove 310 and the second groove 320 can be formed by etching or the like, thereby making the formation process of the first groove 310 and the second groove 320 more convenient.

[0119] For example, the square groove can be configured as follows: the cross-section of the square groove can be a rectangular shape when the plane perpendicular to the extending direction of the square groove is taken as the cross-section. The arc-shaped groove can be configured as follows: the cross-section of the arc-shaped groove can be a semicircular shape when the plane perpendicular to the extending direction of the arc-shaped groove is taken as the cross-section.

[0120] The U-shaped groove can be configured as follows: the cross-section of the U-shaped groove can be set to a U-shape with a plane perpendicular to the extending direction of the U-shaped groove as the cross-section. The triangular groove can be configured as follows: the cross-section of the triangular groove can be set to a triangle with a plane perpendicular to the extending direction of the triangular groove as the cross-section.

[0121] Reference Fig.12 In some possible implementations, the display device may include a cover plate 400 . The cover plate 400 may be attached to the surface of the encapsulation layer 300 facing away from the substrate 100 , and the cover plate 400 may close the notch of the first groove 310 , and the cover plate 400 may close the notch of the second groove 320 .

[0122] The notch of the first groove 310 is closed by the cover plate 400, and the notch of the second groove 320 is closed by the cover plate 400, so that the cover plate 400 can provide certain support and protection for the structures of the first groove 310 and the second groove 320, thereby reducing the possibility of impurities such as dust falling into the first groove 310 or the second groove 320, thereby reducing the influence of impurities such as dust on the bright and dark lines formed by the first groove 310 and the second groove 320, thereby improving the display effect of the display device.

[0123] In summary, a joint seam 11 is formed between adjacent lamp panels 10, and a plurality of first grooves 310 and a plurality of second grooves 320 are arranged in parallel on the encapsulation layer 300. When the plurality of light-emitting elements 200 are in a light-emitting state or a non-light-emitting state, the joint seam 11, the plurality of first grooves 310 and the plurality of second grooves 320 will form bright and dark lines, so that the light and dark lines formed by the joint seam 11, the plurality of first grooves 310 and the plurality of second grooves 320 can form a grid together, and when the pixel unit 201 is in a light-emitting state, the mesh of the grid is at least used for the light-emitting element 200 to emit light.

[0124] When the light and dark lines formed by the splicing seam 11, the multiple first grooves 310 and the multiple second grooves 320 can jointly form a grid, the splicing seam 11 is difficult to distinguish from the first grooves 310 and the second grooves 320, and the light output of the multiple light-emitting elements 200 through the grid is relatively uniform, so that the user is usually not affected by the splicing seam 11 between adjacent light panels 10, thereby reducing the influence of the splicing seam 11 between adjacent light panels 10 on the display effect of the display device, thereby improving the display effect of the display device.

[0125] An embodiment of the present application provides a display device, including a plurality of light boards 10 spliced ​​to each other, with a splicing seam 11 formed between adjacent light boards 10; the light board 10 includes: a substrate 100, a plurality of light-emitting elements 200 arranged on the substrate 100, and an encapsulation layer 300.

[0126] The encapsulation layer 300 is located on a side of the light emitting element 200 away from the substrate 100; the encapsulation layer 300 is provided with a plurality of first grooves 310 arranged in parallel, and a plurality of second grooves 320 arranged in parallel;

[0127] The joint seam 11 , the plurality of first grooves 310 and the plurality of second grooves 320 form a grid. When the plurality of light emitting elements 200 are in a light emitting state, the meshes of the grid are at least used for the light emitting elements 200 to emit light.
