[0001] This application belongs to the field of display technology, and in particular relates to a display device and an electronic device. Background Technology

[0002] With the rapid development of display technology, large format display (LFD) technology has gradually become a development requirement of the display industry; and using multiple displays to splice together to form an ultra-large size splicing screen is one of the main ways to achieve large screen display.

[0003] When a bezel-framed display is used in a large-size video wall, there will be at least two bezel widths between the light-emitting areas of adjacent displays. This results in noticeable visual seams when the video wall displays images, severely affecting the display quality. Summary of the Invention

[0005] In a first aspect, embodiments of this application provide a display device, including:

[0006] At least two display panels are arranged sequentially, and a splicing area is formed between the display areas of two adjacent display panels;

[0007] A cover plate covers at least two of the display panels. The cover plate has a seamless area on the side near the display panel. The cover plate patterning the seamless area is formed with a plurality of spaced micro-particles. The splicing area overlaps with the seamless area at least in the light emission path of the display panel.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] This application provides a display device and an electronic device to solve the problem of visual seams in existing spliced ​​displays, which affect the display effect. The following description will be provided in conjunction with the accompanying drawings.

[0030] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a cross-sectional view of the display device provided in an embodiment of this application. Figure 2 A cross-sectional view of the first type of cover plate provided in the embodiments of this application. Figure 3 A cross-sectional view of a second type of cover plate provided in an embodiment of this application.

[0031] This application provides a display device including at least two display panels 100 and a cover plate 200. The at least two display panels 100 are sequentially spliced ​​together, such as in an array along the X-axis and Y-axis directions. A splicing area 110 is formed between two adjacent spliced ​​display panels 100. Each display panel 100 includes a display area AA and a border area BA. The border area BA is located on at least one side of the display area AA. The splicing area 110 is located between the display areas AA of two adjacent spliced ​​display panels 100. The cover plate 200 covers the multiple display panels 100 and can protect the spliced ​​display panels, which helps to improve the reliability of the display device. A seam-free area 210 is provided on the side of the cover plate 200 near the display panel 100. The cover plate 200 with the patterned seam-free area 210 forms multiple spaced micro-particles 220. In the light emission path of the display panel 100, the splicing area 110 overlaps with the seam-free area 210 at least.

[0032] Understandably, the light emitted from the display panel 100 has a certain divergence angle. The light located above the splicing area 110 changes its transmission path after being refracted by the micro particles 220 and is emitted from the front of the cover plate 200, thereby achieving the purpose of optically eliminating splicing seams and improving the display effect.

[0033] See Figure 4 and Figure 5 As shown, Figure 4 A cross-sectional view of the third type of cover plate provided in the embodiments of this application. Figure 5 A cross-sectional view of a fourth type of cover plate provided in an embodiment of this application.

[0034] In some embodiments, the gaps between adjacent microparticles 220 in the gap-free zone 210 are filled with a refractive material 230, the refractive index of the refractive material 230 being greater than that of the microparticles 220.

[0035] Understandably, the light emitted from the display panel 100 is first refracted by the refractive material 230, which changes the direction of light transmission. The light then enters the micro-particles 220 and is then refracted a second time by the micro-particles 220 before being emitted from the cover plate 200. This avoids beam superposition and maximizes the front light output effect, achieving a seamless visual effect.

[0036] In some embodiments, the refractive material is a material with a refractive index greater than 1.6. This refractive material includes one or more of the following: titanium dioxide, zinc oxide, zinc selenide, and other particles with high refractive properties.

[0037] In some implementations, see Figure 2 and Figure 3As shown, the height of the microparticle 220 is H, where 10μm ≤ H ≤ 30μm. The height H of the microparticle 220 refers to the vertical distance between the root position of the microparticle 220 near the cover plate 200 and the end position of the microparticle 220 near the display panel 100. The height H of the microparticle 220 can be 10μm, 15μm, 20μm, 25μm, 30μm, or other unlisted values. The side of the microparticle 220 near the display panel 100 is flush with the side of the cover plate 200 near the display panel 100. The microparticle 220 is formed by patterning on the surface of the cover plate 200, resulting in a simple processing technology and convenient operation.

[0038] In the same display device, the height of all microparticles 220 may be the same or different. When the height of microparticles 220 is different, the height of each microparticle 220 should meet the range of 10μm to 30μm mentioned above.

[0039] In some implementations, see Figure 2 and Figure 3 As shown, the distance between adjacent microparticles 220 is L, where 30 μm ≤ L ≤ 50 μm. The distance L between adjacent microparticles 220 refers to the distance between the center positions of the root of each microparticle 220 on the side closest to the cover plate 200. The distance L between adjacent microparticles 220 can be 30 μm, 35 μm, 40 μm, 45 μm, 50 μm, or other unlisted values.

[0040] In the same display device, the distance between all adjacent microparticles 220 can be the same or different. When the distance between adjacent microparticles 220 is different, the distance between all adjacent microparticles 220 satisfies the range of 30μm to 50μm.

[0041] In some implementations, see Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the microparticles 220 are cone-shaped or spherical. The cone shape can be a cone or a pyramid, and the spherical shape can be a hemisphere or a three-quarter sphere.

[0042] In the same display device, all micro particles 220 within the same splicing area 110 have the same shape, which can be either conical or spherical. The micro particles 220 within different splicing areas 110 can have different shapes, such as the micro particles 220 in one splicing area 110 having a conical shape and the micro particles 220 in another splicing area 110 having a spherical shape.

[0043] See Figure 6 As shown, Figure 6This is a top view of the seamless area of ​​the display panel provided in an embodiment of this application.

[0044] In some embodiments, in a top-view orientation, multiple microparticles 220 are arranged in an array along a first direction and a second direction. The first direction is the horizontal direction of the display panel 100, and the second direction is the vertical direction of the display panel 100. The angle between the first direction and the second direction in the plane of the display panel 100 can be 80°, 90°, 120°, etc. The microparticles 220 within the same splicing area 110 are arranged in an array, with the same spacing between adjacent microparticles 220. This results in more uniform light emission from the splicing area 110, improving the display effect.

[0045] In some implementations, see Figure 1 As shown, the plurality of display panels 100 include a first display panel 100a and a second display panel 100b arranged adjacent to each other. Both the first display panel 100a and the second display panel 100b include a display area AA and a border area BA. The border area BA is located on at least one side of the display area AA. The border area BA of the first display panel 100a and the border area BA of the second display panel 100b at least partially overlap. The overlapping area corresponds to a splicing area 110. The width of the splicing area 110 is less than the sum of the widths of the border areas BA of the first display panel 100a and the second display panel 100b. This structure reduces the width of the splicing area 110. Since the width of the splicing area 110 is less than the width of the seamless area 210, reducing the seam width of the display panels 100, the width of the seamless area 210 can be reduced, improving the user's visual experience.

[0046] In the above embodiments, see Figure 1 As shown, the horizontal plane of the second display panel 100b is located above the horizontal plane of the first display panel 100a, and the width of the border area BA of the second display panel 100b is greater than the width of the border area BA of the first display panel 100a. This avoids the situation where the first display panel 100a and the second display panel 100b are not on the same horizontal line, which would cause differences in light output.

[0047] In some implementations, see Figure 1 As shown, it also includes a polarizer 300, which is disposed on the side of the plurality of display panels 100 facing the cover plate 200. The cover plate 200 and the polarizer 300 are bonded together by optical adhesive 400.

[0048] In addition, see Figure 1As shown, the display device also includes multiple back plates 500 and pads 600, with the display panel 100, back plates 500, and pads 600 aligned. A first display panel 100a is bonded to the polarizer 300 via optical adhesive 400 on the side facing the polarizer 300. A back plate 500 is disposed on the side of the first display panel 100a away from the polarizer 300, and a pad 600 is disposed on the side of the back plate 500 away from the first display panel 100a. The first display panel 100a and its corresponding back plate 500 have the same width, but the back plate 500 is wider than the corresponding pad 600. A second display panel 100b has a pad 600 disposed on the side facing the polarizer 300, and the pad 600 is bonded to the polarizer 300 via optical adhesive 400. A back plate 500 is disposed on the side of the second display panel 100b away from the polarizer 300. The second display panel 100b and its corresponding back plate 500... The widths of the first display panel 100a and the second display panel 100b are the same, and the thicknesses of the back plate 500 corresponding to the first display panel 100a and the back plate 500 corresponding to the second display panel 100b are the same. The thickness of the back plate 600 corresponding to the first display panel 100a is the same as the thickness of the back plate 600 corresponding to the second display panel 100b. The thickness of the back plate 600 is the same as the sum of the thicknesses of the display panel 100 and the back plate 500. The first display panel 100a and its corresponding back plate 500 are overlapped with the second display panel 100b and its corresponding back plate 500, which facilitates assembly and helps improve the production efficiency of the display device.

[0049] See Figure 1 As shown, the display device also includes an SCF (Super Clean Foam) layer 700, and a first display panel 100a and a second display panel 100b are disposed on the SCF layer 700. For example, a pad 600 corresponding to the first display panel 100a and a back plate 500 corresponding to the second display panel 100b are fixed on the SCF layer 700.

[0050] See Figure 1 As shown, the cover plate 200, polarizer 300 and SCF layer 700 are all front-facing. The cover plate 200, polarizer 300 and SCF layer 700 only need to be designed and bonded together once, resulting in low design and manufacturing costs for the display device.

[0051] See Figure 6 The above, Figure 6 Another cross-sectional view of the display device provided in the embodiments of this application.

[0052] In other embodiments, multiple display panels 100 are arranged on the same layer. A back plate 500 is provided on the side of the display panel 100 away from the cover plate 200. The display panel 100 and the back plate 500 are aligned. A polarizer 300 is provided on the side of the display panel 100 facing the cover plate 200. The cover plates 200 of the polarizer 300 are bonded together with optical adhesive 400. The frame areas BA of adjacent display panels 100 are joined together. There is a certain distance between the frame areas BA of adjacent display panels 100. The distance between the frame areas BA of adjacent display panels 100 corresponds to the width of the splicing area 110. At this time, the width of the seamless area 210 is greater than the width of the splicing area 110.

[0053] This application also provides an electronic device, including a display device and a terminal body according to any of the above embodiments, wherein the display device is fixed to the terminal body. The electronic device can be a mobile terminal, such as an in-vehicle display, smartphone, tablet computer, laptop computer, etc.; it can also be a wearable terminal, such as a smartwatch, smart bracelet, smart glasses, augmented reality device, etc.; or it can be a fixed terminal, such as a desktop computer, television, etc.

[0054] See Figure 1 and Figure 2 As shown, in this embodiment, the display device includes at least two display panels 100 and a cover plate 200. The at least two display panels 100 are sequentially spliced ​​together, such as at least two display panels 100 being sequentially spliced ​​in an array along the X-axis and Y-axis directions. A splicing area 110 is formed between two adjacent spliced ​​display panels 100. Each display panel 100 includes a display area AA and a border area BA. The border area BA is located on at least one side of the display area AA. The splicing area 110 is located between the display areas AA of two adjacent spliced ​​display panels 100. The cover plate 200 covers the multiple display panels 100. The cover plate 200 can protect the spliced ​​display panels and is beneficial to improving the reliability of the display device. A seam-free area 210 is provided on the side of the cover plate 200 near the display panel 100. The seam-free area 210 has multiple spaced micro-particles 220. On the light emission path of the display panel 100, the splicing area 110 overlaps with the seam-free area 210 at least. The light emitted from the display panel 100 has a certain divergence angle. The light located above the splicing area 110 changes its transmission path after being refracted by the micro particles 220 and is emitted from the front of the cover plate 200, thereby achieving the purpose of optically eliminating splicing seams and improving the display effect.
