[0060] It should be noted that the dimensions and shapes of the figures in the accompanying drawings do not reflect actual proportions and are intended only to illustrate the content of the invention. Furthermore, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0061] This invention provides a splicing display device, such as... Figure 1A , Figure 2A and Figure 3A As shown, Figure 1A This is a planar schematic diagram of a splicing display device. Figure 2A This is another planar schematic diagram of a splicing display device. Figure 3A This is another planar schematic diagram of a splicing display device, which includes at least two display panels 100 spliced ​​together. Figure 1Aand Figure 2A Taking two as examples, Figure 3A (Taking four as an example), the display panel 100 includes a display area AA and a border area B surrounding the display area AA. The border areas B of two adjacent display panels 100 form a splicing area BB. The display area AA of the display panel 100 includes: a compensation display area A1 adjacent to the splicing area BB, and a normal display area A2 located on the side of the compensation display area A1 away from the splicing area BB.

[0062] like Figure 1B , 2B , Figure 3B and Figure 3C As shown, Figure 1B for Figure 1A The diagram shown is a schematic representation of a pixel design for a splicing display device. Figure 2B for Figure 2A The diagram shown is a schematic representation of a pixel design for a splicing display device. Figure 3B for Figure 3A The diagram shown is a schematic representation of a pixel design for a splicing display device. Figure 3C for Figure 3A The schematic diagram of another pixel design corresponding to the splicing display device shown shows that the display area AA of the display panel 100 includes multiple rows and columns of pixel units, wherein the pixel unit set in the normal display area A2 is the first pixel unit P1, and the pixel unit set in the compensation display area A1 is the second pixel unit P2; at least a portion of the second pixel unit P2 includes at least two sub-pixel units (taking two as an example, namely P21 and P22) arranged along the extension direction of the splicing area BB (as shown by arrow F);

[0063] like Figure 4 As shown, Figure 4 To compensate for the light emitted from the display area A1 and the splicing area BB, the splicing display device also includes a light path adjustment structure 200 disposed on the light-emitting side of the display panel 100. The light path adjustment structure 200 is configured to transfer the emitted light from a portion of the sub-pixel units (e.g., P21) in the second pixel unit P2 to the splicing area BB before emitting it.

[0064] like Figure 4 As shown, the splicing display device further includes: a first lens structure 300 disposed on the light-emitting side of another part of the sub-pixel units (e.g., P22) in the second pixel unit P2, and a second lens structure 400 disposed in the splicing area BB; the first lens structure 300 is configured to magnify the image displayed by the other part of the sub-pixel units (P22), and the second lens structure 400 is configured to magnify the image displayed by the splicing area BB.

[0065] The splicing display device provided in this embodiment of the invention, by setting a compensation display area adjacent to the splicing area and changing the pixel design of the compensation display area, and by setting a light path adjustment structure that can transfer the emitted light from a portion of the sub-pixel units in the compensation display area to the splicing area, effectively transfers the image displayed by a portion of the sub-pixel units in the compensation display area to the splicing area, thereby eliminating the border effect and achieving seamless splicing of the display panel. Furthermore, by setting a first lens structure on the light-emitting side of the sub-pixel units in the compensation display area where the emitted light is not transferred, and setting a second lens structure in the splicing area, the invention utilizes the magnification effect of the first and second lens structures to make the splicing area and the compensation display area have the same display effect as the normal display area, thus achieving a truly borderless display effect. Therefore, the splicing display device provided in this embodiment of the invention can solve the problem of black border display effect in the splicing area in the prior art, thereby improving the display effect of the splicing display device.

[0066] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 1B , 2B , Figure 3B and Figure 3C As shown, the area of ​​the sub-pixel units (e.g., P21 and P22) is smaller than the area of ​​the first pixel unit P1. Thus, after transferring the image displayed by a portion of the sub-pixel units (e.g., P21) in the second pixel unit P2 to the splicing area BB, the previously luminous sub-pixel unit P21 area in the second pixel unit P2 no longer emits light. If the size of the sub-pixel unit P21 is large, the non-luminous area in the second pixel unit P2 will be large, resulting in black spots appearing in that non-luminous area. Therefore, this invention designs the area of ​​the sub-pixel units to be smaller than the area of ​​the first pixel unit P1, which can reduce the problem of black spot defects.

[0067] Optionally, the first lens structure and the second lens structure can be convex lenses to achieve the effect of image magnification.

[0068] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 4 As shown, the optical path adjustment structure 200 includes at least one set of first inclined mirrors 201 and second inclined mirrors 202. In each set, the first inclined mirrors 201 are disposed on the light-emitting side of a portion of the sub-pixel units (e.g., P21) in the second pixel unit P2, and the second inclined mirrors 202 are disposed between the display panel 100 and the second lens structure 400.

[0069] The first inclined reflector 201 is configured to reflect the emitted light from a portion of the sub-pixel units (e.g., P21) toward the second inclined reflector 202, which is configured to reflect the emitted light toward the light-emitting side of the display panel 100. This allows the image displayed by a portion of the sub-pixel units (e.g., P21) in each of the second pixel units P2 within the compensation display area A1 to be transferred to the splicing area BB for display, thus solving the problem of black borders appearing in the splicing area in the prior art.

[0070] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 4 As shown, the first inclined mirror 201 and the second inclined mirror 202 are planar mirrors. A transparent dielectric layer can be filled between the first inclined mirror 201 and the second inclined mirror 202 to achieve the flatness of the film layer of the optical path adjustment structure 200. A transparent dielectric layer can also be filled between the first lens structure 300 and the second lens structure 400 to achieve the flatness of the film layer of the first lens structure 300 and the second lens structure 400.

[0071] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 4 As shown, the first inclined mirror 201 and the second inclined mirror 202 in each group are arranged in parallel. This ensures that all the light reflected from the first inclined mirror 201 can be reflected by the second inclined mirror 202 before being emitted, thus reducing light loss.

[0072] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 4 As shown, the second inclined reflector 202 set in the splicing area BB can be set close to the compensation display area A1. This can prevent crosstalk and reduce light loss.

[0073] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 4 As shown, the orthographic projection of the first angled reflector 201 on the display panel 100 completely covers the orthographic projection of the sub-pixel unit (e.g., P21) on the display panel 100. In this way, the first angled reflector 201 can completely reflect the light emitted from the sub-pixel unit (e.g., P21) to the splicing area BB. Furthermore, along the direction from the compensation display area A1 to the splicing area BB, the first angled reflector 201 and the second angled reflector 202 are flush. In this way, the second angled reflector 202 can receive all the light reflected by the first angled reflector 201, thereby further avoiding light loss and ensuring that the splicing area BB and the compensation display area A1 have the same display effect.

[0074] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figures 1A-6C As shown, Figure 5A and Figure 6A They are respectively Figure 1B , Figure 3B and Figure 3C Two enlarged planar schematic diagrams of the dashed box D. Figure 5B for Figure 5A A schematic diagram of the corresponding first inclined mirror 201 and second inclined mirror 202. Figure 5C for Figure 5A A planar schematic diagram of the corresponding first lens structure 300 and second lens structure 400. Figure 6B for Figure 6A A schematic diagram of the corresponding first inclined mirror 201 and second inclined mirror 202. Figure 6C for Figure 6A The corresponding first lens structure 300 and second lens structure 400 are schematic diagrams. Each second pixel unit P2 includes a first sub-pixel unit P21 and a second sub-pixel unit P22. A set of first inclined reflectors 201 and second inclined reflectors 202 are correspondingly arranged between the light-emitting side of each first sub-pixel unit P21 and between the display panel 100 and the second lens structure 400. This design divides one pixel unit in the compensation display area A1 into two sub-pixel units. The size (pitch) of each sub-pixel unit can be half the size of one pixel unit in the normal display area A2. That is, in the same layout space, the normal display area A2 and the compensation display area A1 have twice the number of pixel units as the normal display area A2. This pixel design of the compensation display area A1 allows half of the sub-pixel units (e.g., P21) in the compensation display area A1 to be transferred to the splicing area BB for display, while the other half of the sub-pixel units (P22) are responsible for displaying the compensation display area A1. In this way, the resolution of the display pixels in the normal display area A2, the compensation display area A1, and the splicing area BB is the same. Then, by using the first lens structure 300 and the second lens structure 400 to magnify the display images in the compensation display area A1 and the splicing area BB, the normal display area A2, the compensation display area A1, and the splicing area BB can have the same display effect, thereby achieving a true borderless display effect and solving the problem of black border display effect in the splicing area in the prior art.

[0075] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 5A and Figure 6AAs shown, in two adjacent display panels 100 arranged in a splicing configuration, the arrangement of the first sub-pixel unit P21 and the second sub-pixel unit P22 in one display panel 100 is opposite to that in the other display panel 100. For example, Figure 5A and Figure 6A In the left-hand display panel 100, the first sub-pixel unit P21 in the compensation display area A1 is located in an odd-numbered row, and the second sub-pixel unit P22 is located in an even-numbered row. In the right-hand display panel 100, the second sub-pixel unit P22 in the compensation display area A1 is located in an odd-numbered row, and the first sub-pixel unit P21 is located in an even-numbered row. This invention adds a first oblique reflector 201 for reflecting outgoing light at the position of the first sub-pixel unit P21 in the compensation display area A1, and a second oblique reflector 202 for reflecting outgoing light at the position of the image transferred to the splicing area BB (represented by P21'). Figure 5B and Figure 6B The position of the rectangle represents the position of the reflector. This transfers the images displayed by each first sub-pixel unit P21 in the left and right display panels 100 to the splicing area BB (P21'). That is, the splicing area BB uses a design where the images are transferred from the alternate odd and even first sub-pixel units P21 in the left and right display panels 100. Simultaneously, each second sub-pixel unit P22 in the compensation display area A1 of the left and right display panels 100 is responsible for displaying in the compensation display area A1, resulting in better image display. Furthermore, to compensate for the image difference caused by the pixel design difference between the compensation display area A1 and the normal display area A2, this invention adds a first lens structure 300 for image magnification at the position of the second sub-pixel unit P22 in the compensation display area A1 and a second lens structure 400 for image magnification at the position of P21' which has already been transferred to the splicing area BB. Figure 5C and Figure 6C The position of the circle in the middle represents the position of the lens structure, so as to achieve the same display effect for the compensation display area A1, the splicing area BB and the normal display area A2.

[0076] In practical implementation, for large-sized display panels, the width of the bezel area is also relatively large, resulting in a relatively large splicing area after splicing. Therefore, for display devices with a wide splicing area, such as... Figures 5A-5C As shown, the width of the splicing area BB can be greater than or equal to twice the width of the compensation display area A1. Each second inclined reflector 202 is set adjacent to the compensation display area A1, and the first lens structure 300 and the second lens structure 400 are set independently. In this way, the light emitted from the first sub-pixel unit P21 is reflected onto the adjacent second inclined reflector 202, which can reduce light loss.

[0077] In practical implementation, for display devices with narrow splicing areas, such as... Figures 6A-6C As shown, the width of the splicing area BB is greater than or equal to the width of the compensation display area A1 and less than twice the width of the compensation display area A1. This allows each of the second inclined reflectors 202 to be arranged in the same column of the splicing area BB, and the second lens structure 400 located on the side of each second inclined reflector 202 facing away from the display panel 100 can be a single integrated structure. Figure 6C The second lens structure 400 located in the splicing area BB can be an integral structure, which can reduce the manufacturing difficulty of each second lens structure 400; of course, each second lens structure 400 can also be an independent structure. This invention is illustrated by taking the example of each second lens structure 400 being independent.

[0078] Specifically, Figure 6A and Figure 5A The principles for achieving image transfer and image magnification are the same; the only difference between the two is the width of the splicing area (BB).

[0079] In practice, Figure 5A BB design corresponds to a wider splicing area. Figure 6A For the narrower splicing area BB design, due to Figure 6A After the image transfer, the display resolution of the splicing area BB is twice that of the compensation display area A1. In order to ensure that the splicing area BB and the compensation display area A1 display the same image, that is, to ensure that the resolutions of the splicing area BB and the compensation display area A1 are consistent, as follows: Figure 6A As shown, the first sub-pixel units P21 located in the same row on both sides of the splicing area BB (i.e., the first sub-pixel units P21 in the second pixel units P2 in the same row on both the left and right sides) display the same image (loaded with the same data voltage). In this way, the two images P21' transferred to the splicing area BB on the left and right sides of the same row display the same image, thus enabling the splicing area BB and the compensation display area A1 to display the same image, that is, to achieve the same resolution between the splicing area BB and the compensation display area A1.

[0080] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 1B , 2B , Figure 3B and Figure 3C As shown, the display area AA of the display panel 100 includes multiple gate lines (G1, G2...) and multiple data lines (S1...S4...) arranged in an insulated and intersecting manner. The multiple gate lines (G1, G2...) and multiple data lines (S1...S4...) insulated and intersecting define multiple first pixel units P1 and multiple second pixel units P2.

[0081] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 1A and Figure 1B As shown, at least two spliced ​​display panels 100 are spliced ​​along the row direction X. The row direction X can be the extension direction of the grid lines (G1, G2, etc.) in the display panel 100. At this time, the extension direction F of the splicing area BB is the column direction Y. The column direction Y is the extension direction of the data lines (S1, S4, etc.) in the display panel 100. The first sub-pixel unit P21 and the second sub-pixel unit P22 in each column of the second pixel unit P2 in the left and right display panels 100 are alternately arranged along the column direction Y, that is, the second pixel unit P2 is divided into two sub-pixel units along the column direction. However, the positions of the first sub-pixel unit P21 and the second sub-pixel unit P22 in the left and right display panels 100 are opposite, for example... In the left display panel 100, the first sub-pixel unit P21 is located at an odd position in the column direction Y, and the second sub-pixel unit P22 is located at an even position in the column direction Y. In the right display panel 100, the second sub-pixel unit P22 is located at an odd position in the column direction Y, and the first sub-pixel unit P21 is located at an even position in the column direction Y. This allows the images displayed by the first sub-pixel units P21 on both the left and right sides to be transferred to the splicing area BB. The first lens structure 300 magnifies the image displayed by the second sub-pixel unit P22, and the second lens structure 400 magnifies the image transferred to the splicing area BB, thereby achieving the same display effect for the splicing area BB, the compensation display area A1, and the normal display area A2.

[0082] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 2A and Figure 2BAs shown, at least two spliced ​​display panels 100 are spliced ​​along the column direction Y. The column direction Y can be the extension direction of the data lines (S1...S4...) in the display panel 100. At this time, the extension direction F of the splicing area BB is the row direction X. The row direction X is the extension direction of the grid lines (G1, G2...) in the display panel 100. The first sub-pixel unit P21 and the second sub-pixel unit P22 in the second pixel unit P2 of each row are alternately set along the row direction X, that is, the second pixel unit P2 is divided into two sub-pixel units along the row direction. However, the positions of the first sub-pixel unit P21 and the second sub-pixel unit P22 in the upper and lower display panels 100 are opposite. For example, the upper display panel... Within the first sub-pixel unit P21 in the row direction X, the second sub-pixel unit P22 is located at an odd position in the row direction X, and the second sub-pixel unit P22 in the lower display panel 100 is located at an odd position in the row direction X, while the first sub-pixel unit P21 is located at an even position in the row direction X. This allows the images displayed by the first sub-pixel units P21 on both the upper and lower sides to be transferred to the splicing area BB. Furthermore, the first lens structure 300 magnifies the image displayed by the second sub-pixel unit P22, and the second lens structure 400 magnifies the image transferred to the splicing area BB, thereby achieving the same display effect for the splicing area BB, the compensation display area A1, and the normal display area A2.

[0083] It should be noted that the embodiments of the present invention Figure 1A and Figure 1B Taking two display panels 100 spliced ​​together along the X direction as an example, of course, three or more display panels 100 can also be spliced ​​together along the X direction; Embodiment of the present invention Figure 2A and Figure 2B Taking two display panels 100 spliced ​​together along the column direction Y as an example, of course, three or more display panels 100 can also be spliced ​​together along the column direction Y.

[0084] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 3A As shown, at least four display panels 100 are spliced ​​together along the row direction X and the column direction Y. The compensation display area A1 of the display panel 100 includes: a first compensation display area A11 aligned with the normal display area A2 along the row direction X, a second compensation display area A12 aligned with the normal display area A2 along the column direction Y, and a third compensation display area A13 located at the intersection of the extension direction (Y) of the first compensation display area A11 and the extension direction (X) of the second compensation display area A12.

[0085] like Figure 3B and Figure 3C As shown, in the first compensation display area A11, the first sub-pixel unit P21 and the second sub-pixel unit P22 in each row of the second pixel unit P2 are alternately arranged along the row direction X; that is... Figure 3B and Figure 3C The pixel design of the first compensation display area A11 and Figure 1B Same as above;

[0086] like Figure 3B and Figure 3C As shown, in the second compensation display area A12, the first sub-pixel unit P21 and the second sub-pixel unit P22 in each column of the second pixel unit P2 are alternately arranged along the column direction Y; that is... Figure 3B and Figure 3C The pixel design of the second compensation display area A12 and Figure 2B Same as above;

[0087] like Figure 3B As shown, in the third compensation display area A13, the arrangement of the first sub-pixel unit P21 and the second sub-pixel unit P22 within each second pixel unit P2 is the same as that in the first compensation display area A11; that is... Figure 3B The pixel design of the third compensation display area A13 and Figure 1B Same as above;

[0088] Or, such as Figure 3C As shown, in the third compensation display area A13, the arrangement of the first sub-pixel unit P21 and the second sub-pixel unit P22 within each second pixel unit P2 is the same as that in the second compensation display area A12, that is... Figure 3C The pixel design of the third compensation display area A13 and Figure 2B Same as above.

[0089] It should be noted that the embodiments of the present invention Figures 3A-3C This is an example of four display panels 100 arranged in an array. Of course, there can also be more display panels 100 arranged in an array.

[0090] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 7A , Figure 8 , Figure 9A and Figure 10A Show, Figure 7A for Figure 1B A magnified diagram showing the specific pixel structure within the left-hand display panel 100. Figure 8 for Figure 2B A magnified diagram showing the specific pixel structure within the upper display panel 100. Figure 9A for Figure 3B A magnified diagram showing the specific pixel structure within the top left corner of the display panel (100 pixels). Figure 10A for Figure 3CThe enlarged schematic diagram of the specific pixel structure within the display panel 100 in the upper left corner shows that the first pixel unit P1 in the normal display area A2 includes multiple first sub-pixels of different emission colors (e.g., first red sub-pixel R1, first green sub-pixel G1, first blue sub-pixel B1), and the first sub-pixel unit P21 and the second sub-pixel unit P22 in the second pixel unit P2 respectively include multiple second sub-pixels of different emission colors (e.g., second red sub-pixel R2, second green sub-pixel G2, second blue sub-pixel B2). The first pixel units P1 in the same row of the normal display area A2 are electrically connected to the same gate line, and the first sub-pixels in the same column are electrically connected to the same data line. The border area B of the display panel 100 includes a gate driving circuit GOA. The gate driving circuit GOA has scan signal output terminals (Gout1, Gout2, etc.) that correspond one-to-one with the gate lines (G1, G2, etc.) and are electrically connected. The gate driving circuit GOA is used to load scan signals to each corresponding row of gate lines one by one through the scan signal output terminals. Of course, the border area B also includes a source drive circuit (not shown) that is electrically connected to the data lines (S1, S2...), which is used to apply data voltage to the data lines.

[0091] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 1B and Figure 7A As shown, for a display panel 100 spliced ​​along the X-axis, compensation gate lines (G1', G2', ...) are provided between the first sub-pixel unit P21 and the second sub-pixel unit P22 located in the same row as the first pixel unit P1. The first pixel unit P1 and the second sub-pixel unit P22 in the same row are electrically connected to the corresponding gate line of that row. For example, the first pixel unit P1 and the second sub-pixel unit P22 in the first row are electrically connected to the gate line G1 of the first row, the first pixel unit P1 and the second sub-pixel unit P22 in the second row are electrically connected to the gate line G2 of the second row, and so on. Each first sub-pixel unit P21 in the same row is electrically connected to the corresponding compensation gate line. For example, each first sub-pixel unit P21 in the first row is electrically connected to the corresponding compensation gate line. Pixel P21 is electrically connected to the compensation gate line G1' of the first row, and each first sub-pixel unit P21 of the second row is electrically connected to the compensation gate line G2' of the second row, and so on. Furthermore, the gate lines and compensation gate lines corresponding to the pixel units (P1 and P2) in the same row are electrically connected to the same scan signal output terminal of the gate driving circuit GOA. For example, the gate line G1 and compensation gate line G1' corresponding to the pixel units (P1 and P2) in the first row are electrically connected to the first scan signal output terminal Gout1 of the gate driving circuit GOA, and the gate line G2 and compensation gate line G2' corresponding to the pixel units (P1 and P2) in the second row are electrically connected to the second scan signal output terminal Gout2 of the gate driving circuit GOA, and so on.

[0092] The first sub-pixel unit P21 and the second sub-pixel unit P22, located in the same row as the first pixel unit P1, are electrically connected to different data lines. For example, the second red sub-pixel R2 within the first sub-pixel unit P21 and the second sub-pixel unit P22, located in the same row as the first pixel unit P1, is electrically connected to different data lines; the second green sub-pixel G2 within the first sub-pixel unit P21 and the second sub-pixel unit P22, located in the same row as the first pixel unit P1, is electrically connected to different data lines; and the second blue sub-pixel B2 within the first sub-pixel unit P21 and the second sub-pixel unit P22, located in the same row as the first pixel unit P1, is electrically connected to different data lines. They are located in the same column. The second red sub-pixel R2 within each of the first sub-pixel units P21 is electrically connected to the same data line; the second green sub-pixel G2 within each of the first sub-pixel units P21 in the same column is electrically connected to the same data line; the second blue sub-pixel B2 within each of the first sub-pixel units P21 in the same column is electrically connected to the same data line; the second red sub-pixel R2 within each of the second sub-pixel units P22 in the same column is electrically connected to the same data line; the second green sub-pixel G2 within each of the second sub-pixel units P22 in the same column is electrically connected to the same data line; and the second blue sub-pixel B2 within each of the second sub-pixel units P22 in the same column is electrically connected to the same data line. This is equivalent to transferring the first sub-pixel units P21 in the compensation display area A1 to the right splicing area BB. Therefore, the compensation display area A1 requires twice the number of data lines compared to the normal display area A2 for the same number of pixel units.

[0093] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 7A As shown, since the number of second sub-pixels driven by the compensation grid lines (G1', G2'...) is much smaller than the number of first sub-pixels driven by the grid lines (G1, G2...), the RC Loading of the compensation grid lines (G1', G2'...) is much smaller than that of the grid lines (G1, G2...). Therefore, in order to ensure the uniformity of the display image of the first and second sub-pixels, the width of the compensation grid lines (G1', G2'...) can be smaller than the width of the grid lines (G1, G2...) so that the RC Loading of the compensation grid lines (G1', G2'...) is approximately the same as that of the grid lines (G1, G2...).

[0094] In practice, due to Figure 7A The compensation gate lines (G1', G2', ...) are located inside the display area AA. The ends of the compensation gate lines (G1', G2', ...) furthest from the gate drive circuit GOA are prone to static electricity accumulation, causing electrostatic damage to adjacent sub-pixels. Therefore, to solve this problem, in the splicing display device provided in the embodiments of the present invention, as follows... Figure 7B As shown, it also includes an electrostatic discharge (ESD) protection unit electrically connected to the end of each compensation grid line (G1', G2', ...) away from the splicing area BB. The ESD protection unit is located on the side of the compensation display area A1 near the normal display area A2, and is electrically connected to the common voltage line Vcom in the display panel 100. In this way, the ESD protection unit can conduct the static electricity accumulated on the compensation grid lines (G1', G2', ...) to the common voltage line Vcom to release the static electricity and avoid electrostatic damage to adjacent sub-pixels.

[0095] Optionally, the circuit structure of the electrostatic discharge (ESD) protection unit is the same as that of the existing circuit structure capable of electrostatic discharge, and will not be described in detail in this invention.

[0096] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 2B and Figure 8 As shown, for the display panel 100 spliced ​​along the column direction Y, the first sub-pixel unit P21 needs to be moved to the lower splicing area BB. Therefore, the first sub-pixel unit P21 and the second sub-pixel unit P22 located in the same column as the first pixel unit P1 need to be electrically connected to different gate lines. For example, each first sub-pixel unit P21 located in the same row is electrically connected to gate line G6, and each second sub-pixel unit P22 located in the same row is electrically connected to gate line G7. The first sub-pixel unit P21 and the second sub-pixel unit P22 located in the same column as the first pixel unit P1 are electrically connected to the data lines of the corresponding column, that is, the first sub-pixel unit P1 and the second sub-pixel unit P22 within the same second pixel unit P2 are electrically connected to the corresponding data lines. The second sub-pixel of the same color in pixel unit P2 is electrically connected to the data line that connects to the first sub-pixel of the same color in the corresponding column. For example, the second red sub-pixel R2 in the first sub-pixel unit P21 and the second sub-pixel unit P22 in the first column is electrically connected to the data line S1, the second green sub-pixel G2 in the first sub-pixel unit P21 and the second sub-pixel unit P22 in the first column is electrically connected to the data line S2, the second blue sub-pixel B2 in the first sub-pixel unit P21 and the second sub-pixel unit P22 in the first column is electrically connected to the data line S3, and so on. Therefore, the number of grid lines in the compensation display area A1 is doubled compared to the normal display area A2 for the same number of pixel units.

[0097] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 3B , Figure 3C , Figure 9A and Figure 10A As shown, for a display panel 100 simultaneously spliced ​​along the row direction X and the column direction Y, the specific pixel structure design of the first compensation display area A11 is as follows: Figure 7A The specific pixel structure design of the second compensation display area A12 is the same as... Figure 8 same.

[0098] In specific implementation, in the splicing display device provided in the embodiments of the present invention, such as Figure 3B and Figure 9A As shown, when the pixel design of the third compensation display area A13 is the same as that of the first compensation display area A11, the connection relationship between the first sub-pixel unit P21, the second sub-pixel unit P22 of the third compensation display area A13 and the gate line and data line is the same as that of the first compensation display area A11. Figure 7A Same; such as Figure 3C and Figure 10A As shown, when the pixel design of the third compensation display area A13 is the same as that of the second compensation display area A12, the connection relationship between the first sub-pixel unit P21, the second sub-pixel unit P22 of the third compensation display area A13 and the gate line and data line is the same as that of the second compensation display area A12. Figure 8 same.

[0099] In specific implementation, in order to prevent Figure 9A and Figure 10A The ends of the compensation gate lines (G1', G2', ...) furthest from the gate drive circuit GOA are prone to static electricity accumulation, causing electrostatic damage to adjacent sub-pixels. In the splicing display device provided in the embodiments of the present invention, such as... Figure 9B and Figure 10B The display panel 100 also includes an electrostatic discharge (ESD) protection unit electrically connected to the end of each compensation grid line (G1', G2', ...) away from the splicing area BB. The ESD protection unit is located on the side of the compensation display area A1 closest to the normal display area A2, and is electrically connected to the common voltage line Vcom in the display panel 100. This allows the ESD protection unit to conduct static electricity accumulated on the compensation grid lines (G1', G2', ...) onto the common voltage line Vcom to release the static electricity and prevent electrostatic damage to adjacent sub-pixels.

[0100] It should be noted that the embodiments of the present invention all take the compensation display area including one row and / or one column of second pixel units as an example. Of course, the size of the compensation display area can be determined according to the size of the splicing area. For example, if the splicing area is wider, the compensation display area will also be designed to be wider, and if the splicing area is narrower, the compensation display area will also be designed to be narrower. For example, in a display panel spliced ​​along the row direction, when the compensation display area includes two or more columns of second pixel units, it is necessary to transfer the image displayed by each first sub-pixel unit in each column of the second pixel unit to the splicing area; in a display panel spliced ​​along the column direction, when the compensation display area includes two or more rows of second pixel units, it is necessary to transfer the image displayed by each first sub-pixel unit in each row of the second pixel unit to the splicing area.

[0101] In specific implementations, the display panel provided in the embodiments of the present invention can be an OLED display panel or an LCD display panel, but is not limited to these.

[0102] Optionally, taking the LCD display panel provided in the embodiments of the present invention as an example, sub-pixels generally have structures such as pixel circuits and pixel electrodes, and the pixel circuits generally include structures such as thin-film transistors. Figure 11 As shown, Figure 11 for Figure 1B The diagram shows the connection relationship of some pixel circuits, pixel electrodes, gate lines and data lines in the left side of the display panel. The number of first pixel electrodes PA1 in the second pixel unit P2 in the compensation display area A1 is twice the number of second pixel electrodes PA2 in the first pixel unit P1 in the normal display area A2, and the size of the first pixel electrode PA1 is half that of the second pixel electrode PA2. For example, the thin-film transistors in the first pixel unit P1 and the second sub-pixel unit P22 are first thin-film transistors T1, and the thin-film transistors in the first sub-pixel unit P21 are second thin-film transistors T2. Gate lines (e.g., G1) are electrically connected to the gates of each first thin-film transistor T1, and compensation gate lines (e.g., G1') are electrically connected to the gates of each second thin-film transistor T2. Each data line is electrically connected to the source of the corresponding first thin-film transistor T1 or second thin-film transistor T2. The drain of each first thin-film transistor T1 is electrically connected to the first pixel electrode PA1 in the second sub-pixel unit P22 and the second pixel electrode PA2 in the first pixel unit P1, respectively. The drain of each second thin-film transistor T1 is electrically connected to the first pixel electrode PA1 in the first sub-pixel unit P21. The positions of the second thin-film transistors T2 and T1 in the compensation display area A1 are different. For example, the first thin-film transistor T1 is located at the lower right corner of the first pixel electrode PA1, and the second thin-film transistor T2 is located at the lower left corner of the first pixel electrode PA1, so as to be electrically connected to the adjacent data lines.

[0103] This invention discloses a splicing display device that, by setting a compensation display area adjacent to the splicing area and modifying the pixel design of the compensation display area, and by setting a light path adjustment structure that can transfer the emitted light from a portion of the sub-pixel units in the compensation display area to the splicing area, effectively transfers the image displayed by a portion of the sub-pixel units in the compensation display area to the splicing area, thereby eliminating the border effect and achieving seamless splicing of the display panel. Furthermore, this invention sets a first lens structure on the light-emitting side of the sub-pixel units in the compensation display area where the emitted light is not transferred, and a second lens structure in the splicing area. By utilizing the magnification effect of the first and second lens structures, the splicing area and the compensation display area can be made to have the same display effect as the normal display area, thus achieving a truly borderless display effect. Therefore, the splicing display device provided by this invention can solve the problem of black border display effects in the splicing area in the prior art, thereby improving the display effect of the splicing display device.

[0104] Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the invention.

[0105] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations to the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
