Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a display module and a display device. Background Art

[0002] With the iteration and update of semiconductor display technology, a larger screen-to-body ratio is one of the primary directions of display technology development. The reduction of the aperture of the front camera and the four-sided frame has become the development trend of display devices. Figure 1 As shown, it is a basic structural diagram of a display module of the prior art, wherein the display module includes a display panel 100, a polarizer 400 and a cover plate 300, a light-shielding layer 200 (i.e., ink) is provided on one side of the cover plate 300, and the polarizer 400 is bonded to the side of the cover plate 300 provided with the light-shielding layer 200 through optical adhesive 500.

[0003] like Figure 2 As shown, it is a top view of the cover plate of the prior art. The light shielding layer 200 and the cover plate 300 of the prior art are integrated. The light shielding layer 200 is set corresponding to the hole area and the frame area of ​​the four sides of the display panel 100, and the purpose is to block the light leakage from the edge of the display panel 100. However, the manufacturer of the cover plate 300 generally adopts the silk screen printing / pad printing process to make the light shielding layer 200. Due to the limitation of the manufacturing precision, the manufacturing tolerance of the light shielding layer 200 reaches ±150 microns. In addition, the fitting tolerance of the cover plate 300 is ±150 microns (the fitting tolerance of the 3D cover plate is larger), so that a wider light shielding area needs to be set on the display panel 100 to prevent the cover plate 300 from sticking to the pixels in the display area, and the light shielding layer 200 needs to be widened to prevent the cutting path of the edge of the display panel 100 from being exposed. Therefore, it is not conducive to achieving an extremely narrow frame. Therefore, it is necessary to improve this defect. Summary of the invention

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. In the accompanying drawings, for the sake of clarity and ease of understanding and description, the sizes and thicknesses of the components shown in the accompanying drawings are not in proportion.

[0030] like Figure 3 As shown, it is a cross-sectional schematic diagram of the hole-digging area of ​​the display module of the prior art. The width of the light-shielding area of ​​the display panel 100 corresponding to the hole-digging area is A (A=B+D+E), wherein the B area is set to prevent the cover plate 300 from shifting toward the display area when being attached, resulting in the pixels in the display area being blocked, that is, the B area corresponds to the bonding tolerance, and no pixels are set in the B area; the E area is set to prevent the optical glue 500 from being offset in the attachment, resulting in the colloid overflowing into the cutting path, so the optical glue 500 adopts a retracted design. In addition, the F area is set to cover the edge of the polarizer 400 (that is, the cutting path) to prevent the polarizer 400 from being exposed due to the offset of the cover plate 300, that is, the F area also corresponds to the bonding tolerance. Therefore, in order to prevent the light-shielding layer 200 from covering the pixels in the display area and to ensure that the edge of the polarizer 400 is covered, the width of the light-shielding layer is set to D+E+F, and the overall width of the frame of the hole-digging area is L (L=A+F). Furthermore, since the manufacturing precision of the light shielding layer 200 on the cover plate 300 is limited, it is difficult to achieve an extremely narrow frame.

[0031] like Figure 4 , which is a cross-sectional view of the frame area of ​​a display module in the prior art, the width of the light shielding area of ​​the display panel 100 corresponding to the frame area is A (A=B+D+E). Figure 3Similar to the F area in FIG. 1 , the G area is also set to cover the edge of the cutting path. That is, the overall width of the frame of the frame area is L (L=A+G). Therefore, the overall width of the frame of the display module is relatively wide, which is not conducive to achieving an extremely narrow frame. The embodiments of the present invention can solve the above defects.

[0032] like Figure 5 , Figure 6 As shown, they are respectively a first structural schematic diagram of a display module provided in an embodiment of the present invention and a second structural schematic diagram of a display module, wherein the display module comprises a display panel 100, a light-shielding layer 200 and a cover plate 300; the display panel 100 comprises a display area A1 and a light-shielding area A2 located at the edge of the display area A1, and the display panel 100 comprises an organic light-emitting layer 101; the light-shielding layer 200 is located on the organic light-emitting layer 101, and the light-shielding layer 200 is arranged in the light-shielding area A2; the cover plate 300 is located on the light-shielding layer 200, and the cover plate 300 is separately arranged from the light-shielding layer 200; wherein, one end of the light-shielding layer 200 away from the display area A1 is flush with the edge of the display panel 100.

[0033] It is understandable that the light shielding layer 200 is used to shield the edge of the display panel 100 to prevent light leakage from the edge of the display panel 100. In the prior art, the light shielding layer 200 is manufactured on the cover plate 300, and then the side of the cover plate 300 provided with the light shielding layer 200 is laminated to the polarizer 400 on the display panel 100, which not only has limited manufacturing accuracy, but also has lamination tolerance. The embodiment of the present invention can use the inkjet printing equipment or magnetron sputtering equipment or evaporation equipment used in the production process of the display panel 100 to spray the shading material on the organic light-emitting layer 101 in situ, and has high production precision (production tolerance is ±10 microns), and no fitting tolerance, thereby improving the production tolerance and fitting tolerance caused by the current integration of the shading layer 200 and the cover plate 300. In addition, the end of the shading layer 200 away from the display area A1 is flush with the edge of the display panel 100, that is, the shading layer 200 is cut together with the display panel 100, and the cutting line is L0. There is no need to widen the shading layer 200 to cover the cutting path, which is conducive to achieving an extremely narrow frame.

[0034] It should be noted that the material of the light shielding layer 200 is ink or other light shielding materials. The present invention does not impose any limitation on the material of the light shielding layer 200. Any material having light shielding properties is acceptable. When the material of the light shielding layer 200 is an organic material, after the display panel 100 and the light shielding layer 200 are manufactured, the light shielding layer 200 and the display panel 100 are cut together. The cutting is performed by laser cutting. During the cutting process, the high temperature will cause the edge of the light shielding layer 200 to be carbonized, that is, black residues (such as carbon chips) will exist on the edge of the light shielding layer 200 after cutting.

[0035] In one embodiment, the display panel 100 includes a first through hole 10, and the light shielding layer 200 includes a first light shielding portion 201, and the first light shielding portion 201 is arranged around the first through hole 10. That is, the product corresponding to this embodiment is a hole-punch screen (such as a static curved display screen), wherein the first light shielding portion 201 is used to shield the edge of the first through hole 10.

[0036] In this embodiment, the material of the first light shielding portion 201 is directly made on the organic light emitting layer 101 by inkjet printing, magnetron sputtering or evaporation, and is cut together with the display panel 100, which is different from the conventional hole area (such as Figure 3 ), not only the manufacturing accuracy is improved, but also the overall width of the frame of the hole-digging area of ​​the embodiment is A (corresponding to the shading area A2 of the display panel 100), minus Figure 3 The F area in the display area (at least 180 microns) is reduced, that is, the overall width of the frame of the hole area is reduced, which is conducive to achieving an extremely narrow frame. In other embodiments, since there is no fitting tolerance, the light shielding layer 200 will not shift and block the pixels of the display area A1. Therefore, the Figure 3 The width of area B in the hole-digging area is reduced, thereby further reducing the overall width of the frame of the hole-digging area, and reducing the overall width of the frame to D+E, that is, the end of the light-shielding layer 200 close to the display area A1 coincides with the edge of the display area A1, and area B belongs to the display area A1, and pixels can also be set, thereby increasing the area of ​​the display area A1 of the display panel 100.

[0037] In one embodiment, the display module includes a polarizer 400, the polarizer 400 is located between the display panel 100 and the cover plate 300, the polarizer 400 is formed with a second through hole 20 at a position corresponding to the first through hole 10, and the end of the first light shielding portion 201 away from the display area A1 is flush with the edge of the second through hole 20; wherein the first light shielding portion 201 is located on a side surface of the display panel 100 close to the polarizer 400 (such as Figure 5 ); or the first light shielding portion 201 is located on a side surface of the polarizer 400 away from the display panel 100 (such as Figure 6 ).

[0038] It should be noted that the first light-shielding portion 201 can be arranged on the upper surface of the display panel 100, that is, the encapsulation layer (not shown) is made and then the first light-shielding portion 201 is made, and then the polarizer 400 is attached, and then the polarizer 400, the first light-shielding portion 201 and the display panel 100 are cut together; or the polarizer 400 is first attached to the upper surface of the display panel 100, and then the light-shielding layer 200 is made on the upper surface of the polarizer 400, and then the first light-shielding portion 201, the polarizer 400 and the display panel 100 are cut together.

[0039] It should be noted that the side of the polarizer 400 away from the display panel 100 is still adhered to the cover plate 300 through the optical adhesive 500. Since the light shielding layer 200 is directly made on the display panel 100 or the polarizer 400, there is no fitting tolerance.

[0040] It should be noted that a support layer 600 is disposed on the surface of the display panel 100 away from the polarizer 400 , and an ultra-clean foam structure 700 is disposed on the surface of the support layer 600 away from the display panel 100 . The ultra-clean foam structure 700 plays a buffering role.

[0041] Next, see Figure 7 , is a third structural schematic diagram of the display module provided in an embodiment of the present invention. In this embodiment, the display module includes a color filter layer 800, and the color filter layer 800 is located on a side surface of the display panel 100 close to the cover plate 300. The color filter layer 800 is formed with a third through hole 30 at a position corresponding to the first through hole 10, and an end of the first shading portion 201 away from the display area A1 is flush with an edge of the third through hole 30; wherein, the first shading portion 201 is located on a side surface of the color filter layer 800 away from the display panel 100.

[0042] It is understandable that since the thickness of the polarizer 400 is relatively thick, the present embodiment adopts a design without the polarizer 400. In the present embodiment, the polarizer 400 is replaced by the color filter layer 800, which can significantly reduce the thickness of the display module. In the present embodiment, by setting the first shading portion 201 on the upper surface of the color filter layer 800, there is no fitting tolerance, which is conducive to achieving an extremely narrow frame.

[0043] Next, see Figure 8 , is a fourth structural schematic diagram of a display module provided in an embodiment of the present invention, and Figure 7 Compared with the display module of the embodiment, the display module of the present embodiment further includes an organic protective layer 900, which is located on a side of the display panel 100 close to the cover plate 300, and a fourth through hole 40 is formed on the organic protective layer 900 corresponding to the position of the first through hole 10, and an end of the first light shielding portion 201 away from the display area A1 is flush with an edge of the fourth through hole 40; wherein, the first light shielding portion 201 is located on a surface of the side of the organic protective layer 900 away from the display panel 100.

[0044] It can be understood that, in this embodiment, an organic protective layer 900 is disposed on the upper surface of the color filter layer 800. The organic protective layer 900 can protect the color filter layer 800 and the display panel 100 during the cutting process to avoid damage to the color filter layer 800 and the display panel 100 caused by the cutting. In this embodiment, the first light shielding portion 201 is disposed on the upper surface of the organic protective layer 900, so there is no fitting tolerance, which is conducive to achieving an extremely narrow frame.

[0045] It should be noted that in static curved display screens, especially 3D screens, the outline of the cover plate 300 is larger than the frame of the whole device, so the light shielding layer 200 on the cover plate 300 must be used to cover the light shielding area A2 around the edges of the display panel 100. That is, for 3D screens, the above implementation method of reducing the overall width of the frame can only be used in the hole-punch area, and is not applicable to the surrounding frame area. However, for dynamic curved display screens, the camera is generally not on the display panel 100, so there is no hole-punch area design. If there is a hole-punch area on the display panel 100, you can also refer to Figures 5 to 8 In addition, since all the film materials in the dynamic bending display screen are organic and foldable, an externally expanded middle frame is required to fix them, which is different from the case of a 3D screen.

[0046] For details, please refer to Fig. 9 , Fig.10 , respectively, are the fifth structural schematic diagram of the display module provided by the embodiment of the present invention and the sixth structural schematic diagram of the display module provided by the embodiment of the present invention. In this embodiment, the light shielding layer 200 includes a second light shielding portion 202, and the second light shielding portion 202 is arranged around the display area A1. That is, the second light shielding portion 202 of this embodiment is arranged at the four edges of the display panel 100 to shield the four edges of the display panel 100. Figures 9 to 12 Only one frame of the display panel 100 is taken as an example for illustration.

[0047] It should be noted that the cover plate 300 in the dynamic bending display screen generally adopts an organic film material (such as a PI / PET substrate), which is different from the prior art design of integrating the light shielding layer 200 and the cover plate 300. The embodiment of the present invention adopts an inkjet printing device or a magnetron sputtering device or an evaporation device to process the light shielding layer 200 in situ and directly make it on the organic light-emitting layer 101, which not only improves the manufacturing accuracy, but also eliminates the fitting tolerance. In addition, the end of the second light shielding portion 202 away from the display area A1 is flush with the edge of the display panel 100, that is, the second light shielding portion 202 is cut together with the display panel 100, and the cutting line is L1. There is no need to widen the light shielding layer 200 to cover the cutting path, which is conducive to achieving an extremely narrow frame. Figures 9 to 12 The middle cover 300 exceeds the position of the cutting line L1 and will eventually be covered by the middle frame of the entire device.

[0048] from Figures 9 to 12 It can be clearly seen that the overall width of the frame area of ​​the frame region of the present embodiment is A (corresponding to the light shielding area A2 of the display panel 100), which is different from the frame area of ​​the prior art (such as Figure 4 ) compared to Figure 4 The G region in the frame is reduced (at least 180 microns), that is, the overall width of the frame in the frame area is reduced, which is conducive to achieving an extremely narrow frame. In other embodiments, since there is no fitting tolerance, the second light shielding portion 202 will not shift and block the pixels of the display area A1. Therefore, the Figure 4 The width of the B area in the frame area is reduced, thereby further reducing the overall width of the frame area, and the overall width of the frame is reduced to D+E, that is, the end of the second shading portion 202 close to the display area A1 coincides with the edge of the display area A1, and the B area belongs to the display area A1, and pixels can also be set, thereby increasing the area of ​​the display area A1 of the display panel 100.

[0049] It should be noted that Figures 9 to 12 The frame in the figure can correspond to the upper, lower, left and right frames of the display module; or it can correspond to only the upper, left and right frames. This is because the lower frame has a bending process, so that the length of the lower frame of the cover plate 300 is larger than the length of the display panel 100 after bending. Therefore, in addition to the light shielding layer 200 on the display panel 100, the assembly part of the whole machine also needs to be fixed with black colloid, or the light shielding layer 200 of the lower frame is completely retained on the cover plate 300.

[0050] In one embodiment, the display module includes a polarizer 400, the polarizer 400 is located between the display panel 100 and the cover plate 300, and the end of the second light shielding portion 202 away from the display area A1 is flush with the edge of the polarizer 400; wherein the second light shielding portion 202 is located on a side surface of the display panel 100 close to the polarizer 400 (such as Fig. 9 ); or the second light shielding portion 202 is located on a side surface of the polarizer 400 away from the display panel 100 (eg Fig.10 ).

[0051] It should be noted that the second light-shielding portion 202 can be arranged on the upper surface of the display panel 100, that is, the encapsulation layer (not shown) is made and then the second light-shielding portion 202 is made, and then the polarizer 400 is attached, and then the polarizer 400, the second light-shielding portion 202 and the display panel 100 are cut together; or the polarizer 400 is first attached to the upper surface of the display panel 100, and then the light-shielding layer 200 is made on the upper surface of the polarizer 400, and then the second light-shielding portion 202, the polarizer 400 and the display panel 100 are cut together.

[0052] It should be noted that the side of the polarizer 400 away from the display panel 100 is still adhered to the cover plate 300 through the optical adhesive 500. Since the second light shielding portion 202 is directly made on the display panel 100 or the polarizer 400, there is no fitting tolerance.

[0053] Next, see Fig.11 , is a seventh structural schematic diagram of the display module provided in an embodiment of the present invention. In this embodiment, the display module includes a color filter layer 800, and the color filter layer 800 is located on a side surface of the display panel 100 close to the cover plate 300, and the end of the second light shielding portion 202 away from the display area A1 is flush with the edge of the color filter layer 800; wherein, the second light shielding portion 202 is located on a side surface of the color filter layer 800 away from the display panel 100.

[0054] It can be understood that since the thickness of the polarizer 400 is relatively thick, the present embodiment adopts a design without the polarizer 400. In the present embodiment, the polarizer 400 is replaced by the color filter layer 800, which can significantly reduce the thickness of the display module. In the present embodiment, by setting the second shading portion 202 on the upper surface of the color filter layer 800, there is no fitting tolerance, which is conducive to achieving an extremely narrow frame.

[0055] Next, see Fig.12 , is a schematic diagram of an eighth structure of a display module provided in an embodiment of the present invention, and Fig.11 Compared with the display module of the embodiment, the display module of the present embodiment further includes an organic protective layer 900, which is located on a side of the display panel 100 close to the cover plate 300, and an end of the second light shielding portion 202 away from the display area A1 is flush with an edge of the organic protective layer 900; wherein the second light shielding portion 202 is located on a surface of the side of the organic protective layer 900 away from the display panel 100.

[0056] It can be understood that, in this embodiment, an organic protective layer 900 is disposed on the upper surface of the color filter layer 800. The organic protective layer 900 can protect the color filter layer 800 and the display panel 100 during the cutting process to avoid damage to the color filter layer 800 and the display panel 100 caused by the cutting. In this embodiment, a second light-shielding portion 202 is disposed on the upper surface of the organic protective layer 900, so there is no fitting tolerance, which is conducive to achieving an extremely narrow frame.

[0057] In one embodiment, the light-shielding layer 200 includes a first light-shielding portion 201 and a second light-shielding portion 202, wherein the cutting of the hole-digging area and the frame area adopts a laser cutting process, wherein after cutting, a cutting inclination angle formed by the second light-shielding portion 202 is greater than a cutting inclination angle formed by the first light-shielding portion 201. This is because the energy released by the cutting process of the hole-digging area is high, the corresponding cutting accuracy is high, and the cutting inclination angle formed after cutting is smaller.

[0058] The embodiment of the present invention further provides a display device, including a display module and a driving chip, wherein the driving chip is electrically connected to the display module. Figures 5 to 12 The display device provided by the embodiment of the present invention can be: a mobile phone, a tablet computer, a notebook computer, a television, a digital camera, a navigator and other products or components with display functions.

[0059] The above is a detailed introduction to a display module and a display device provided by an embodiment of the present invention. It should be understood that the exemplary embodiments described herein should only be considered as descriptive, used to help understand the method and core concept of the present invention, and are not used to limit the present invention.
