[0046] The display panel provided in the present application can be applied to a TFT glass-based COG (Chip on glass) direct display spliced ​​large screen or a PCB-based spliced ​​large screen.

[0047] Combine the following Figure 1 , Figure 2 , Figure 5 and Figure 6 The display panel 200 provided in the present application is described.

[0048] The display panel 200 provided in the present application includes a plurality of display screens 100, and the display screens 100 include a display substrate 10 and a first protective member 20. The first protective member 20 and the display substrate 10 are stacked and arranged along a first direction, and the first protective member 20 is located on one side or both sides of the display substrate 10 in the first direction; along the first direction, the projection of the display substrate 10 toward the first protective member 20 is located within the outer contour of the first protective member 20.

[0049] In applications, such as Figure 1 As shown, the first direction is Figure 1 In the z direction shown in FIG. , the first protective member 20 and the display substrate 10 are arranged along Figure 1 Stacked arrangement in z direction, Figure 1 The z direction is the thickness direction of the first protection member 20 and the thickness direction of the display substrate 10 .

[0050] In some embodiments, the first protective member 20 is located on one side of the display substrate 10 along the first direction z, that is, the light emitting side of the display substrate 10. Thus, the first protective member 20 protects the light emitting structure such as the LED pixel layer 12 on the light emitting side of the display substrate 10.

[0051] In some other embodiments, the first protective member 20 is located on the other side of the display substrate 10 along the first direction z, that is, the backlight side of the display substrate 10. Thus, the first protective member 20 increases the structural strength of the display screen 100.

[0052] In other embodiments, the number of the first protective members 20 is multiple, a portion of the first protective members 20 is located on one side of the display substrate 10 along the first direction z (the light emitting side of the display substrate 10), and another portion of the first protective members 20 is located on the other side of the display substrate 10 along the first direction z (the backlight side of the display substrate 10).

[0053] Therefore, on the one hand, the first protective member 20 protects the light emitting structure such as the LED pixel layer 12 on the light emitting side of the display substrate 10 , and on the other hand, the first protective member 20 increases the structural strength of the display screen 100 .

[0054] Along the first direction z, the projection of the display substrate 10 toward the first protective member 20 is located within the outer contour of the first protective member 20 .

[0055] It should be noted that the outer contour of the projection of the display substrate 10 in the first direction z is a closed line in any plane orthogonal to the first direction z, and the outer contour of the projection of the first protective member 20 in the first direction z is a closed line in any plane orthogonal to the first direction z. When the projected outer contour of the display substrate 10 in the first direction z and the projected outer contour of the first protective member 20 in the first direction z are projected into the same plane, any point on the projected outer contour of the display substrate 10 is located inside the area enclosed by the projected outer contour of the first protective member 20.

[0056] In applications, such as Figure 3 As shown, the projection of the display substrate 10 in the first direction z is as shown in FIG. Figure 3 As shown in FIG. 1 , the first protective member 20 includes a protective plate 22 and an encapsulation protective layer 21. The projection outer contours of the protective plate 22 and the encapsulation protective layer 21 in the first direction z are as shown in FIG. Figure 3 As shown in the figure, the first protective member 20 extends to both sides of the display substrate 10 in the x direction in the figure and both sides of the display substrate 10 in the y direction in the figure, so that the display substrate 10 can be protected in the x direction and the y direction by the first protective member 20. The x direction and the y direction are directions parallel to the surface of the display substrate 10, and the x direction and the y direction are respectively perpendicular to the first direction z.

[0057] The plurality of display screens 100 are arranged along a direction orthogonal to the first direction z, and the first protection members 20 of any two adjacent display screens 100 abut against each other to form a display panel 200 .

[0058] In applications, such as Figure 5 and Figure 6As shown, the display panel 200 provided in the present application is formed by splicing multiple display screens 100 provided in the present application along the x direction and the y direction in the figure. On the one hand, the display panel 200 provided in the present application has the advantage that the display substrate 10 and the wiring 13 are not easily damaged when spliced ​​with each other. On the other hand, the display panel 200 provided in the present application has the advantage that the joints formed after splicing with each other are not easily noticeable and the visual effect is better.

[0059] Therefore, on the one hand, the display panel 200 provided in the present application is formed by splicing multiple smaller display screens 100 together, which reduces the processing cost of the display panel 200. On the other hand, the display panel 200 provided in the present application also has the advantages of imperceptible seams and better visual effects.

[0060] The beneficial effect of the display panel provided by the present application is that: compared with the prior art, the display screen body 100 of the display panel provided by the present application is stacked with a first protective member 20 on the display substrate 10, and the projected outer contour of the display substrate 10 in the first direction z is located on the inner side of the projected outer contour of the first protective member 20 in the first direction z, so that the display substrate 10 is protected by the first protective member 20 at the peripheral side of the display substrate 10 orthogonal to the first direction z, thereby preventing the display substrate 10 from being damaged by external forces orthogonal to the first direction z, and further preventing the display substrate 10 from being damaged when multiple display screen bodies 100 are seamlessly contacted and spliced ​​to form a display panel 200, so that the display panel 200 formed by seamlessly splicing multiple display screen bodies 100 provided by the present application has the advantage of a lower failure rate.

[0061] In some embodiments provided in the present application, the display substrate 10 includes a substrate 11, an LED pixel layer 12 disposed on the substrate 11, and a wiring 13, one end of the wiring 13 is connected to the LED pixel layer 12, and the other end of the wiring 13 extends from between two adjacent display screens 100 to a side of the substrate 11 away from the LED pixel layer 12.

[0062] In application, the substrate 11 can be a glass substrate or a PCB board, such as Figure 2 , Figure 3 and Figure 4 As shown, the thickness direction of the substrate 11 is the z direction shown in the figure, and the LED pixel layer 12 is arranged on one side of the thickness direction z of the substrate 11. The LED pixel layer 12 is composed of a plurality of RGB pixel points 121 arrayed flat on one side of the thickness direction z of the substrate 11.

[0063] In some embodiments, the RGB pixel point 121 includes a red LED chip, a green LED chip and a blue LED chip arranged in parallel, and the display panel 200 provided in the present application is a direct display LED screen.

[0064] One end of the wiring 13 extends to the LED pixel layer 12 and is connected to the RGB pixel point 121 in the LED pixel layer 12. The wiring 13 bypasses the side of the substrate 11 along the x direction in the figure and extends to the side of the substrate 11 away from the LED pixel layer 12, so as to supply power to multiple RGB pixel points 121 through the wiring 13 to drive their bright spots. The display substrate 10 includes multiple wirings 13, and the multiple wirings 13 are arranged in parallel and spaced apart along the y direction in the figure, and the projection of the multiple wirings 13 in the z direction in the figure is located on the inner side of the outer contour of the projection of the first protective member 20 in the z direction in the figure.

[0065] Therefore, the projection of the wiring 13 in the z direction in the figure is also located on the inner side of the outer contour of the projection of the first protective member 20 in the z direction in the figure, so as to prevent the wiring 13 from being worn in the x direction in the figure when multiple display screens 100 are spliced ​​together or the display substrate 10 provided in the present application is installed in a frame.

[0066] In some embodiments provided in the present application, the first protective member 20 includes a protective plate 22, which is stacked on the side of the substrate 11 away from the LED pixel layer 12. Along the first direction z, the projection of the display substrate 10 toward the protective plate 22 is located within the outer contour of the protective plate 22.

[0067] In applications, such as Figure 2 As shown, the protection plate 22 is arranged on the side of the substrate 11 away from the LED pixel layer 12, and the protection plate 22 extends to both sides of the display substrate 10 in the x direction in the figure and both sides in the y direction in the figure, so as to protect the display substrate 10 on the circumferential side of the display substrate 10 orthogonal to the first direction z, so as to prevent the display substrate 10 provided in the present application from being worn orthogonal to the first direction z when multiple display screens 100 are spliced ​​with each other or the display substrate 10 is installed in a frame.

[0068] In some embodiments, the protective plate 22 is made of metal material so that the protective plate 22 has a high bending resistance to improve the bending strength of the display screen 100. At the same time, the protective plate 22 also has appropriate elasticity to avoid breakage and failure of the protective plate 22 when bent, thereby enhancing the protective effect of the protective plate 22 on the display substrate 10.

[0069] In some embodiments, the protection plate 22 is connected to the side of the substrate 11 away from the LED pixel layer 12 by gluing. On the one hand, it can reduce the difficulty of processing the protection plate 22 on the substrate 11 and improve the processing efficiency. On the other hand, it can prevent the protection plate 22 from damaging part of the wiring 13 on the side of the substrate 11 away from the LED pixel layer 12 during the process of being processed onto the substrate 11.

[0070] In some embodiments provided in the present application, the first protective member 20 also includes an encapsulation protective layer 21, which is stacked on the side of the LED pixel layer 12 facing away from the substrate 11. Along the first direction z, the projection of the display substrate 10 toward the encapsulation protective layer 21 is located within the outer contour of the encapsulation protective layer 21.

[0071] In application, the encapsulation protection layer 21 may be a material with a light transmittance greater than 90% (such as transparent PET), or the encapsulation protection layer 21 may be a transparent material with some diffusion particles added to the transparent PET.

[0072] like Figure 2 As shown, the encapsulation protective layer 21 is arranged on the side of the LED pixel layer 12 away from the substrate 11, that is, the encapsulation protective layer 21 is located on the light emitting side of the display substrate 10, so that the LED pixel layer 12 is sandwiched between the encapsulation protective layer 21 and the substrate 11, and the encapsulation protective layer 21 is a transparent material so that the light generated by the LED pixel layer 12 can be transmitted through the encapsulation protective layer 21. The encapsulation protective layer 21 extends to both sides of the display substrate 10 in the x direction in the figure and both sides in the y direction in the figure, so as to protect the display substrate 10 on the circumferential side of the display substrate 10 orthogonal to the first direction z.

[0073] Therefore, on the one hand, the packaging protection layer 21 is used to protect the multiple RGB pixel points 121 in the LED pixel layer 12, thereby reducing the failure rate of bad pixels in the LED pixel layer 12. On the other hand, the packaging protection layer 21 is used to protect the display substrate 10 on the peripheral side of the display substrate 10 that is orthogonal to the first direction z, so as to prevent the display substrate 10 provided in the present application from being worn orthogonal to the first direction z when multiple display screens 100 are spliced ​​with each other or the display substrate 10 is installed in a frame.

[0074] In some embodiments provided in the present application, the encapsulation protection layer 21 has a flange 211, which extends out of the display substrate 10 in a direction orthogonal to the first direction z. Along the first direction z, the projection of the display substrate 10 toward the flange 211 is located on the inner side of the flange 211, and the flange 211 is made of elastic material.

[0075] It should be noted that the flange 211 is the portion of the encapsulation protective layer 21 extending out from both sides of the display substrate 10 along the x direction in the figure and the portion of the encapsulation protective layer 21 extending out from both sides of the display substrate 10 along the y direction in the figure, so that the inner contour of the projection of the flange 211 in the first direction z is located outside the projection of the display substrate 10 in the first direction z.

[0076] In some embodiments, the encapsulation protection layer 21 is integrally formed with the flange 211, and the material of the encapsulation protection layer 21 is an elastic transparent material such as transparent PET, that is, the material of the flange 211 is also an elastic transparent material such as transparent PET, so that the two adjacent display screens 100 produce slight deformation when spliced ​​to reduce the appearance of the joint between the two adjacent display screens 100, thereby improving the user experience.

[0077] In some other embodiments, only the material of the flange 211 in the packaging protection layer 21 is a transparent material with elasticity such as transparent PET, so that only the edge of the packaging protection layer 21 has elasticity.

[0078] In some embodiments provided in the present application, along the first direction z, the projection of the protection plate 22 toward the encapsulation protection layer 21 is located within the outer contour of the encapsulation protection layer 21 .

[0079] In applications, such as Figure 1 , Figure 2 and Figure 3 As shown, the dimensions of the protection plate 22 in the x direction and the y direction in the figure are both smaller than the dimensions of the encapsulation protection layer 21 in a direction orthogonal to the first direction z, so that the outer contour of the protection plate 22 projected in the first direction z is located on the inner side of the outer contour of the encapsulation protection layer 21 projected in the first direction z.

[0080] Therefore, the encapsulation protective layer 21 extends to both sides of the protection plate 22 and the display substrate 10 in the x direction in the figure and both sides in the y direction in the figure. When multiple display screens 100 provided in the present application are spliced ​​with each other, the encapsulation protective layers 21 of two adjacent display screens 100 are abutted against each other for splicing. On the one hand, the encapsulation protective layer 21 is located on the outside of the display direction of the display screen 100. The abutment of the encapsulation protective layers 21 can effectively reduce the roughness of the surface of the spliced ​​display screen 100, reduce the visual perception at the joint and improve the user experience. On the other hand, the size of the display substrate 10 in a direction orthogonal to the first direction is smaller than the encapsulation protective layer 21, thereby avoiding contact between the display substrates 10 of two adjacent display screens 100 when multiple display screens 100 are spliced, thereby reducing the occurrence of damage to the substrate 11 of the display screen 100 or damage to the wiring 13 when multiple display screens 100 are spliced.

[0081] In some embodiments provided in the present application, the display screen 100 further includes a second protective member 30, which is disposed on at least one side of the display substrate 10 orthogonal to the first direction z, and the wiring 13 is encapsulated between at least a portion of the second protective member 30 and the substrate 11;

[0082] Along the first direction z, the projection of the second protection member 30 toward the encapsulation protection layer 21 is located within the outer contour of the encapsulation protection layer 21 , or the projection outer contour of the second protection member 30 along the first direction z coincides with the projection outer contour of the encapsulation protection layer 21 along the first direction z.

[0083] In applications, such as Figure 1 and Figure 2 As shown, the second protective member 30 is disposed on the outer peripheral side of the display substrate 10 along the first direction z orthogonal to the first direction, and the second protective member 30 is coated on the side of the wiring 13 facing away from the substrate 11 .

[0084] Therefore, on the one hand, the second protective layer can protect the wiring 13 to avoid damage to the wiring 13 when multiple display screens 100 are spliced ​​together. On the other hand, the second protective layer can protect the substrate 11 of the display substrate 10 in a direction orthogonal to the first direction z, thereby reducing the probability of mutual wear of the substrates 11 when multiple display screens 100 are spliced ​​together.

[0085] In some embodiments, the dimension of the encapsulation protection layer 21 orthogonal to the first direction z is larger than the dimension of the second protection member 30 orthogonal to the first direction z, so that the outer contour of the second protection member 30 in the first direction z is located inside the outer contour of the projection of the encapsulation protection layer 21 in the first direction z.

[0086] In other embodiments, the outer contour dimension of the encapsulation protection layer 21 orthogonal to the first direction z is the same as the outer contour dimension of the second protection member 30 orthogonal to the first direction z, so that the outer contour of the second protection member 30 in the first direction z coincides with the projected outer contour of the encapsulation protection layer 21 in the first direction z.

[0087] Therefore, when two adjacent display screens 100 are spliced ​​along a direction orthogonal to the first direction z, when the encapsulation protection layers 21 of the two adjacent display screens 100 abut against each other, and the second protection components 30 of the two adjacent display screens 100 also abut against each other, on the one hand, the second protection components 30 of the two adjacent display screens 100 abut against each other to have a sealing effect, preventing foreign matter from penetrating from the gap between the encapsulation protection layers 21 of the two display screens 100 to the display substrate 10 to protect the display substrate 10, and on the other hand, the second protection components 30 of the two adjacent display screens 100 can be filled in the gap between the display substrates 10 of the two adjacent display screens 100, thereby reducing the visual perception of the joint to enhance the user experience.

[0088] In some embodiments, along the first direction z, a projection of the protection plate 22 toward the second protection member 30 is located within an outer contour of the second protection member 30 .

[0089] In some embodiments provided in the present application, an annular groove 31 is formed between the encapsulation protection layer 21 and the protection plate 22 . The annular groove 31 is closed and extends along the outer periphery of the display substrate 10 around the first direction z. The second protection member 30 is filled in the annular groove 31 .

[0090] In applications, such as Figure 1 and Figure 2 As shown, the encapsulation protective layer 21, the display substrate 10 and the protection plate 22 are stacked in sequence, the size of the display substrate 10 orthogonal to the first direction z is smaller than the size of the encapsulation protective layer 21 orthogonal to the first direction z, and the size of the display substrate 10 orthogonal to the first direction z is smaller than the size of the protection plate 22 orthogonal to the first direction z, so that an annular groove 31 is generated between the encapsulation protective layer 21 and the protection plate 22, the annular groove 31 extends in a closed circumferential direction around the first direction z of the display substrate 10, and the bottom of the annular groove 31 is the multiple side walls of the display substrate 10.

[0091] Thus, the second protective member 30 is filled in the annular groove 31. On the one hand, the second protective layer can protect the wiring 13 to avoid damage to the wiring 13 when multiple display screens 100 are spliced ​​together. On the other hand, the second protective layer can protect the substrate 11 of the display substrate 10 in the dimensions in the x direction in the figure and the dimensions in the y direction in the figure, thereby reducing the probability of mutual wear of the substrates 11 when multiple display screens 100 are spliced ​​together.

[0092] In some embodiments provided in the present application, the reflectivity of the second protective member 30 to visible light is lower than a set threshold. In applications, the reflectivity of the second protective member 30 to visible light is lower than 4%, so that the second protective member 30 appears black or other colors under visible light.

[0093] Therefore, after the multiple display screens 100 are spliced ​​together, the visual color of the encapsulation protective layer 21 is changed to black through the black second protective member 30. On the one hand, it can improve the contrast of the multiple display screens 100 after splicing. On the other hand, the black second protective member 30 can absorb the light in the environment, making the seams between adjacent display screens 100 less visible visually, thereby improving the user experience.

[0094] In some embodiments provided in the present application, the second protective member 30 is an elastic material. In application, the second protective member 30 is a black colloid, and the second protective member 30 can be processed into the annular groove 31 by means of glue injection. Therefore, on the one hand, it is convenient to process the second protective member 30 into the narrow space in the annular groove 31, and on the other hand, the second protective member 30 is an elastic material, which can improve the sealing of the abutment between the second protective members 30 of the two display screens 100 when the two display screens 100 are spliced.

[0095] Combine the following Figures 1 to 6 The display panel processing method proposed in this application is described.

[0096] The display panel processing method provided in this application includes:

[0097] A plurality of display substrates 10 are provided, and first protective members 20 are processed one by one on the display substrates 10, the first protective members 20 and the display substrates 10 are stacked along a first direction z, and a projection of the display substrates 10 along the first direction z is located within an outer contour of the first protective member 20;

[0098] The first protection members 20 on two adjacent display substrates 10 are abutted against each other along a direction perpendicular to the first direction z to form a display panel 200 .

[0099] In applications, such as Figure 4 As shown, the display substrate 10 can be a TFT glass substrate or a PCB substrate processed with an LED pixel layer 12, the LED pixel layer 12 is connected to the wiring 13 arranged on one side of the substrate 11 along the x direction in the figure, and the first protective member 20 is processed on one side or both sides of the display substrate 10 along the z direction in the figure to form a display screen 100, and the size of the first protective member 20 along the first direction z is larger than the size of the display substrate 10 along the first direction z, so that the projection outline of the display substrate 10 in the first direction z is located on the inner side of the projection outline of the first protective member 20 in the first direction z.

[0100] Therefore, when multiple display screens 100 are spliced ​​along a direction orthogonal to the first direction z, the encapsulation protective layers 21 of two adjacent display screens 100 are abutted against each other for splicing. On the one hand, the encapsulation protective layers 21 are located on the outside of the display direction of the display screen 100. The abutment of the encapsulation protective layers 21 can effectively reduce the roughness of the surface of the spliced ​​display screens 100, reduce the visual perception at the joints and improve user experience. On the other hand, the size of the display substrate 10 in a direction orthogonal to the first direction is smaller than the encapsulation protective layer 21, thereby avoiding contact between the display substrates 10 of two adjacent display screens 100 when the multiple display screens 100 are spliced, thereby reducing the occurrence of damage to the substrate 11 of the display screen 100 or damage to the wiring 13 when the multiple display screens 100 are spliced.

[0101] In some embodiments provided in the present application, processing the first protective member 20 on the display substrate 10 in a one-to-one correspondence includes: processing the encapsulation protective layer 21 on the light-emitting side of the display substrate 10 in a one-to-one correspondence, and the projection of the display substrate 10 along the first direction z is located on the inner side of the outer contour of the projection of the encapsulation protective layer 21 in the first direction z.

[0102] In application, the encapsulation protective layer 21 can be a material with a transmittance greater than 90% (such as transparent PET), or a transparent material with some diffusion particles added to the transparent PET. The encapsulation protective layer 21 has a certain toughness so that it can produce slight deformation when two adjacent display screens 100 are spliced ​​together to reduce the visual appearance of the seam between the two adjacent display screens 100 and improve the user experience.

[0103] In applications, the encapsulation protection layer 21 can be processed on the light-emitting side of the display substrate 10 by lamination, deposition, or the like.

[0104] In some embodiments provided in the present application, processing the first protective member 20 on the display substrate 10 in a one-to-one correspondence includes: processing the protective plate 22 on the backlight side of the display substrate 10 in a one-to-one correspondence, and the projection of the display substrate 10 along the first direction z is located on the inner side of the outer contour of the projection of the protective plate 22 in the first direction z.

[0105] In applications, such as Figure 2 As shown, the protection plate 22 is bonded to the backlight side of the display substrate 10 by means of a frame glue 40. It should be noted that the light emitting side of the display substrate 10 is the side of the display substrate 10 on which the LED pixel layer 12 is provided, and the backlight side of the display substrate 10 is the side of the display substrate 10 which is away from the LED pixel layer 12 on its surface.

[0106] In some embodiments, processing the first protective member 20 on the display substrate 10 in a one-to-one correspondence only includes processing the encapsulation protective layer 21 on the light-emitting side of the display substrate 10 .

[0107] In some other embodiments, processing the first protective member 20 on the display substrate 10 in a one-to-one correspondence only includes processing the protective plate 22 on the backlight side of the display substrate 10 .

[0108] In some other embodiments, processing the first protective member 20 on the display substrate 10 in a one-to-one correspondence includes first processing the encapsulation protective layer 21 on the light-emitting side of the display substrate 10 , and then processing the protective plate 22 on the backlight side of the display substrate 10 .

[0109] In some embodiments provided in the present application, the display panel processing method further includes:

[0110] The second protective member 30 is processed one-to-one on one or more sides of the display substrate 10 orthogonal to the first direction z, and the second protective member 30 is located inside the projected outer contour of the encapsulation protection layer 21 in the first direction z.

[0111] In application, the second protective member 30 is black rubber, such as Figure 1 and Figure 2As shown, the encapsulation protective layer 21, the display substrate 10 and the protective plate 22 are stacked in sequence, the size of the display substrate 10 at a direction perpendicular to the first direction z is smaller than the size of the encapsulation protective layer 21 at a direction perpendicular to the first direction z, and the size of the display substrate 10 at a direction perpendicular to the first direction z is smaller than the size of the protective plate 22 at a direction perpendicular to the first direction z, so that an annular groove 31 is generated between the encapsulation protective layer 21 and the protective plate 22, and the second protective member 30 can be processed in the annular groove 31 by dispensing or the like so that the second protective member 30 is filled in the annular groove 31 after solidification.

[0112] Thus, the second protective member 30 is filled in the annular groove 31. On the one hand, the second protective layer can protect the wiring 13 to prevent the wiring 13 from being damaged when multiple display screens 100 are spliced ​​together. On the other hand, the second protective layer can protect the substrate 11 of the display substrate 10 in a direction orthogonal to the first direction z, thereby reducing the probability of mutual wear of the substrate 11 when multiple display screens 100 are spliced ​​together. The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
