Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly relates to a display panel and a splicing panel. Background Art

However, when using a conventional pixel arrangement, since there is also a layer of encapsulant on the LED device, the light emitted by the outermost LED device undergoes total internal reflection at the encapsulant interface, resulting in a color bright line visible from the side at the splicing gap, as Figure 2 shown.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the orientation terms such as "upper" and "lower" usually refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the drawings; and "inner" and "outer" refer to the outline of the device.

[0037] Embodiments of the present application provide a display panel and a splicing panel, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0038] Please refer to Figure 3 , embodiments of the present application provide a display panel 100, which includes a display area AA. The display area AA includes a middle area A1 and an edge area A2, and the edge area A2 is disposed on the opposite side or one side of the middle area A1.

[0039] In this embodiment, the case where the edge area A2 is disposed on the opposite side of the middle area A1 is taken as an example; the number of the edge areas A2 is two, one edge area A2 is disposed on one side of the middle area A1, and the other edge area A2 is disposed on the other side of the middle area A1; that is, the two edge areas A2 are disposed opposite to each other with the middle area A1 therebetween, as Figure 3 shown.

[0040] In addition, in some embodiments, the number of the edge areas A2 may be one, and one edge area A2 may be disposed on any side of the middle area A1.

[0041] The display panel 100 includes a substrate 11 and a plurality of pixels 12. The pixels 12 are disposed on the substrate 11. The plurality of pixels 12 includes a plurality of first pixels 1a and a plurality of second pixels 1b.

[0042] The plurality of first pixels 1a are disposed in the middle area A1. The plurality of second pixels 1b are disposed in the edge area A2. The first pixel 1a includes a plurality of first light-emitting devices 1a1 with different light-emitting colors. The second pixel 1b includes a plurality of second light-emitting devices 1b1 with different light-emitting colors.

[0043] In the first direction X, the plurality of first pixels 1a are arranged in a pixel row h. In a second direction Y intersecting with the first direction X, the plurality of first pixels 1a are arranged in a first pixel row v1, and the plurality of second pixels 1b are arranged in a second pixel row v2.

[0044] The display area AA includes a first edge w1 and a second edge w2 connected to the first edge w1. The first edge w1 is parallel to the first direction X. The second edge w2 is parallel to the second direction Y.

[0045] Among the first pixels 1a in the pixel row h closest to the first edge w1 in the middle area A1, the plurality of first light-emitting devices 1a1 are arranged along the first direction X. Among the second pixels 1b in the second pixel row v2 closest to the second edge w2 in the edge area A2, the plurality of second light-emitting devices 1b1 are arranged along the second direction Y.

[0046] The long axis direction of the first light-emitting device 1a1 is parallel to the second direction Y, and the short axis direction of the first light-emitting device 1a1 is parallel to the first direction X. The long axis direction of the second light-emitting device 1b1 is parallel to the first direction X, and the short axis direction of the second light-emitting device 1b1 is parallel to the second direction Y.

[0047] In the display panel 100 according to the embodiment of the present application, a pixel row h arranged with a plurality of first pixels 1a is provided at the first edge w1 of the display area AA. The first pixel 1a includes a plurality of first light-emitting devices 1a1 with different emission colors, and the long axis direction of the first light-emitting device 1a1 is parallel to the second direction Y; that is, in the row direction at the first edge w1, the emission colors of two adjacent first light-emitting devices 1a1 are different; when the display panel 100 is spliced and arranged along the second direction Y, the light emitted by the first pixel 1a at the splicing gap is reflected by the interface of the encapsulation layer 13 (see Figure 4 ), and sufficient light mixing can be performed, thereby reducing the risk of color bright lines appearing at the splicing gap.

[0048] At the second edge w2 of the display area AA, a second pixel row v2 arranged with a plurality of second pixels 1b is provided. The second pixel 1b includes a plurality of second light-emitting devices 1b1 with different emission colors, and the long axis direction of the second light-emitting device 1b1 is parallel to the first direction X. When the display panel 100 is spliced and arranged along the first direction X, the light emitted by the second pixel 1b at the splicing gap is reflected by the interface of the encapsulation layer 13, and sufficient light mixing can be performed, thereby reducing the risk of color bright lines appearing at the splicing gap.

[0049] Therefore, in the display panel 100 of this embodiment, light-emitting devices with different emission colors are arranged at the first edge w1 and the second edge w2 respectively, reducing the risk of color bright lines appearing at the splicing gaps in the first direction X and the second direction Y of the display panel 100.

[0050] Optionally, the first direction X and the second direction Y are perpendicularly arranged; of course, in some embodiments, they may also be non-perpendicularly arranged, such as being inclined at 30°, 45° or 60°.

[0051] Optionally, the middle area A1 includes multiple pixel rows h. The edge area A2 includes at least one row of second pixel rows v2. At least one row of second pixel rows v2 is arranged at intervals along the first direction X. Herein, this embodiment takes the edge area A2 having one row of second pixel rows v2 as an example for elaboration.

[0052] In addition, a pixel row h may include a second pixel 1b; that is, a pixel row h includes at least one second pixel 1b and a plurality of first pixels 1a. For example, a pixel row h includes two second pixels 1b and a plurality of first pixels 1a. One second pixel 1b is disposed on one side of the middle region A1, and the other second pixel 1b is disposed on the other side of the middle region A1.

[0053] Optionally, the area of the first pixel 1a is equal to the area of the second pixel 1b. In the first direction X and / or in the second direction Y, the center distance between two adjacent pixels 12 is the pixel pitch d1, and any two pixel pitches d1 are equal.

[0054] That is, the above settings make the pixel pitch d1 in the middle region A1 and the edge region A2 consistent, ensuring a good display effect.

[0055] Optionally, the first pixel 1a includes a first light-emitting device 1a1 that emits red light, a first light-emitting device 1a1 that emits green light, and a first light-emitting device 1a1 that emits blue light. The second pixel 1b includes a second light-emitting device 1b1 that emits red light, a second light-emitting device 1b1 that emits green light, and a second light-emitting device 1b1 that emits blue light.

[0056] In the first direction X, the first light-emitting device 1a1 that emits red light, the first light-emitting device 1a1 that emits green light, and the first light-emitting device 1a1 that emits blue light are arranged at intervals in turn.

[0057] In the second direction Y, a plurality of first light-emitting devices 1a1 that emit red light are arranged in columns, a plurality of first light-emitting devices 1a1 that emit green light are arranged in columns, and a plurality of first light-emitting devices 1a1 that emit blue light are arranged in columns; and the second light-emitting device 1b1 that emits red light, the second light-emitting device 1b1 that emits green light, and the second light-emitting device 1b1 that emits blue light are arranged at intervals in turn.

[0058] In addition, in the first direction X of the middle region A1, the distance between any two adjacent first light-emitting devices 1a1 is equal, and the first light-emitting devices 1a1 are arranged at equal intervals. In the second direction Y of the edge region A2, the distance between any two adjacent second light-emitting devices 1b1 is equal, and the second light-emitting devices 1b1 are arranged at equal intervals.

[0059] Optionally, the first light-emitting device 1a1 and the second light-emitting device 1b1 may be a micro light-emitting diode (Micro-LED) or a sub-millimeter light-emitting diode (Mini-LED) respectively.

[0060] Optionally, the light-emitting areas and shapes of the first light-emitting device 1a1 and the second light-emitting device 1b1 with the same light-emitting color are the same. The difference between the first light-emitting device 1a1 and the second light-emitting device 1b1 lies in the different placement directions. For example, rotating the first light-emitting device 1a1 by 90° gives the second light-emitting device 1b1.

[0061] That is to say, when a light-emitting device is placed horizontally and vertically, it is the first light-emitting device 1a1; when it is placed horizontally and laterally, it is the second light-emitting device 1b1. Therefore, in this embodiment, by using three different colors of light-emitting devices in different placement manners, the arrangement of the above-mentioned pixel 12 can be achieved, saving the demand for the types of light-emitting devices and improving the transfer efficiency.

[0062] Optionally, the outer contour shapes of the first pixel 1a and the second pixel 1b are both rectangles. The long axis direction of the first pixel 1a is parallel to the first direction X. The long axis direction of the second pixel 1b is parallel to the second direction Y.

[0063] It should be noted that although the long axis direction of the first pixel 1a is parallel to the first direction X, the long axis direction of the first light-emitting device 1a1 is perpendicular to the first direction X. Similarly, although the long axis direction of the second pixel 1b is parallel to the second direction Y, the long axis direction of the second light-emitting device 1b1 is perpendicular to the second direction Y.

[0064] In this way, the long axis of the first pixel 1a is composed of the short axes of multiple first light-emitting devices 1a1, and the long axis of the second pixel 1b is composed of the short axes of multiple second light-emitting devices 1b1, making the first pixel 1a and the second pixel 1b approach a square respectively, improving the display effect.

[0065] In addition, when there are only a small number of second pixel rows v2 in the edge region A2, the outermost first pixel row v1 is very close to the second edge w2 of the display area AA. Therefore, the outermost pure-color first light-emitting device 1a1 of the first pixel row v1 will also increase the risk of color bright lines. In this embodiment, among adjacent first pixels 1a and second pixels 1b, three second light-emitting devices 1b1 with different light-emitting colors are arranged on one side of a first light-emitting device 1a1, achieving a light mixing effect and further reducing the risk of color bright lines appearing at the splicing gap when the display panel 100 is spliced.

[0066] In some embodiments, the outer contour shapes of the first pixel 1a and the second pixel 1b are both squares. Please refer to Figure 4 When the first pixel 1a and the second pixel 1b are squares, the resolution of the pixels 12 in the entire display area AA is consistent, improving the display effect.

[0067] Please refer to Figure 5 The display panel 100 further includes a packaging layer 13. The packaging layer 13 is disposed on the substrate 11 and packages the pixels 12.

[0068] Optionally, the material of the packaging layer 13 can be a transparent glue-like material.

[0069] In the thickness direction Z perpendicular to the plane where the substrate 11 is located, the thickness of the part of the encapsulation layer 13 corresponding to covering the pixel 12 is H, and 110 μm ≤ H ≤ 220 μm.

[0070] In the first direction X, the distance from the edge of the encapsulation layer 13 to the nearest second light-emitting device 1b1 is L1, and 140 μm ≤ L1 ≤ 240 μm.

[0071] It can be understood that the thickness of the encapsulation layer 13 and the distance from the second light-emitting device 1b1 to the edge of the encapsulation layer 13 also have an impact on the color bright lines. For example, the thinner the thickness of the encapsulation layer 13, the smaller the reflection interface provided by the encapsulation layer 13, and the smaller the energy of the light reflected; the greater the distance from the second light-emitting device 1b1 to the side surface (total reflection interface) of the encapsulation layer 13, as the distance increases, the higher the height of the light emitted by the second light-emitting device 1b1 radiating to the interface, and the greater the light loss, and thus the smaller the energy of the light reflected; thereby the risk of the appearance of color bright lines can be reduced.

[0072] However, the smaller the thickness of the encapsulation layer 13, the worse its encapsulation effect; the greater the distance from the second light-emitting device 1b1 to the side surface (total reflection interface) of the encapsulation layer 13, the less conducive to a narrow border.

[0073] Therefore, in order to meet the requirements for the encapsulation effect of the light-emitting devices (1a1 and 1b1), narrow border, and the reflectivity of the side surface of the encapsulation layer 13, the inventor obtained through countless experiments that when 110 μm ≤ H ≤ 220 μm and 140 μm ≤ L1 ≤ 240 μm, good effects can be achieved.

[0074] Optionally, H can be 110 μm, 130 μm, 150 μm, 170 μm, 190 μm, 200 μm, or 220 μm. L1 can be 140 μm, 150 μm, 170 μm, 190 μm, 200 μm, 230 μm, or 240 μm.

[0075] Optionally, in the second direction Y, the distance from the edge of the encapsulation layer 13 to the nearest first light-emitting device 1a1 is L2, and 140 μm ≤ L2 ≤ 240 μm. For example, L2 can be 140 μm, 150 μm, 170 μm, 190 μm, 200 μm, 230 μm, or 240 μm.

[0076] In another embodiment, please refer to Figure 6 , the display panel 100 further includes an encapsulation layer 13, and the encapsulation layer 13 is disposed on the substrate 11 and encapsulates the pixel 12. In the cross-section perpendicular to the plane where the substrate 11 is located, the side surface 13a of the encapsulation layer 13 is arc-shaped.

[0077] That is, different from the above embodiments, the side surface 13a of the encapsulation layer 13 is designed to be arc-shaped. This can not only reduce the total reflection rate of the side surface 13a of the encapsulation layer 13, but also adjust the light emission angle to disperse the light, thereby further reducing the risk of color bright lines; at the same time, it can shorten the lengths of L1 and L2 to achieve a narrower border.

[0078] In yet another embodiment, please refer to Figure 7 , different from the above embodiments, the display panel 100 further includes an encapsulation layer 13 and a coating layer 14. The encapsulation layer 13 is disposed on the substrate 11 and encapsulates the pixels 12. The coating layer 14 is formed on the encapsulation layer 13, and the coating layer 14 is used to encapsulate the pixels 12.

[0079] The thickness of the encapsulation layer 13 is greater than the thickness of the coating layer 14.

[0080] It can be understood that the encapsulation layer 13 adopts a coating process, and due to process limitations, the thickness of the encapsulation layer 13 is relatively large. The coating layer 14 adopts a coating process, such as a vapor deposition process and an atomic layer deposition process; the coating process can achieve the performance of low film thickness and high water and oxygen resistance.

[0081] Therefore, the encapsulation method of stacking the encapsulation layer 13 and the coating layer 14 can thin the overall encapsulation thickness compared with only using the encapsulation layer for encapsulation, thereby reducing the risk of color bright lines.

[0082] Optionally, the material of the coating layer 14 can be an inorganic material or an organic material.

[0083] Please refer to Figure 8 , correspondingly, the embodiment of the present application further provides a splicing panel 1000, which includes at least two display panels 100 as described in any one of the above embodiments. At least two display panels 100 are spliced along the first direction X and / or the second direction Y.

[0084] Optionally, adjacent two display panels 100 are spliced to form a splicing gap fx. The color lights emitted by two second light-emitting devices 1b1 that are spaced apart from the splicing gap fx and are oppositely arranged are the same.

[0085] Such a setting makes the light loss of the second light-emitting devices 1b1 arranged opposite to each other at the splicing gap fx consistent, improving the display effect.

[0086] In some embodiments, the emission colors of the second light-emitting devices 1b1 arranged opposite to each other at the splicing gap fx can also be different.

[0087] Among them, in this embodiment, four display panels 100 are spliced along the first direction X and the second direction Y as an example.

[0088] In the first direction X, two display panels 100 are spliced to form a splicing gap fx1; in the second direction Y, two display panels 100 are spliced to form a splicing gap fx2. At the splicing gap fx1, the light-emitting colors of the second light-emitting devices 1b1 that are opposite to each other one by one are the same; at the splicing gap fx2, the light-emitting colors of the first light-emitting devices 1a1 that are opposite to each other one by one are the same.

[0089] In the splicing panel 1000 of the embodiment of the present application, a pixel row h arranged with a plurality of first pixels 1a is provided at the first edge w1 of the display area AA of the display panel 100. The first pixel 1a includes a plurality of first light-emitting devices 1a1 with different light-emitting colors, and the long axis direction of the first light-emitting device 1a1 is parallel to the second direction Y; that is, in the row direction at the first edge w1, the light-emitting colors of two adjacent first light-emitting devices 1a1 are different; when the display panel 100 is spliced and arranged along the second direction Y, the light emitted by the first pixel 1a at the splicing gap is reflected by the interface of the encapsulation layer 13 (see Figure 4 ), and sufficient light mixing can be performed, thereby reducing the risk of color bright lines appearing at the splicing gap.

[0090] At the second edge w2 of the display area AA, a second pixel row v2 arranged with a plurality of second pixels 1b is provided. The second pixel 1b includes a plurality of second light-emitting devices 1b1 with different light-emitting colors, and the long axis direction of the second light-emitting device 1b1 is parallel to the first direction X. When the display panel 100 is spliced and arranged along the first direction X, the light emitted by the second pixel 1b at the splicing gap is reflected by the interface of the encapsulation layer 13, and sufficient light mixing can be performed, thereby reducing the risk of color bright lines appearing at the splicing gap.

[0091] Therefore, in the splicing panel 1000 of this embodiment, light-emitting devices with different light-emitting colors are arranged at the first edge w1 and the second edge w2 respectively, reducing the risk of color bright lines appearing at the splicing gaps in the first direction X and the second direction Y of the splicing panel 1000.

[0092] The above has introduced in detail a display panel and a splicing panel provided by the embodiments of the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
