Description

[Technical Field]

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

[0002] Micro-LEDs are characterized by high efficiency, high brightness, high reliability, and fast response time. They also have self-emissive properties and offer advantages such as energy saving, simple structure, small size, and thinness, making them widely used in the field of display technology.

[0003] In existing Micro-LED display panels, due to the very small size of Micro-LEDs, when users observe the display panel up close, they will find that the light-emitting area of ​​each pixel is small, and there are obvious black areas between the light-emitting areas of adjacent pixels, affecting the user's viewing experience. This is especially true for low-pixel-density Micro-LED display panels, where the black areas are particularly noticeable, severely impacting display quality.

[0004] [Application Content]

[0005] In view of this, embodiments of this application provide a display panel and a display device to solve the above problems.

[0006] In a first aspect, embodiments of this application provide a display panel, the display panel including a plurality of pixel regions, the pixel regions including a first region and a second region, the first region including a pixel unit, the pixel unit including at least two light-emitting devices with different light-emitting colors, the second region surrounding at least a portion of the first region, the second region including a first reflective structure; wherein, the first reflective structure surrounds at least a portion of the light-emitting devices in the pixel unit.

[0007] In one implementation of the first aspect, the display panel includes a light guide structure, at least a portion of which is located on the side of the pixel unit facing the light-emitting surface of the display panel; the light guide structure overlaps at least partially with the pixel unit and the first reflective structure along the thickness direction of the display panel.

[0008] In one implementation of the first aspect, the light guide structure in the display panel is a discontinuous structure.

[0009] In one implementation of the first aspect, the light guide structure includes a plurality of first scattering particles.

[0010] In one implementation of the first aspect, the light guide structure includes a first portion located in a first region and a second portion located in a second region, wherein the concentration of first scattering particles in the first portion is greater than the concentration of first scattering particles in the second portion.

[0011] In one implementation of the first aspect, the display panel includes a second reflective structure located on the side of the pixel unit facing the light-emitting surface of the display panel, and the second reflective structure at least partially overlaps with the pixel unit along the thickness direction of the display panel.

[0012] In one implementation of the first aspect, the second reflective structure partially overlaps with the first reflective structure along the thickness direction of the display panel.

[0013] In one implementation of the first aspect, the display panel further includes second scattering particles attached to the surface of the light guide structure facing the light-emitting surface of the display panel.

[0014] In one implementation of the first aspect, the pixel unit includes three light-emitting devices with different light-emitting colors; the display panel also includes a light-absorbing structure located between adjacent light-guiding structures.

[0015] In one implementation of the first aspect, the display panel includes a substrate, a first reflective structure and a pixel unit located on the same side of the substrate; wherein the distance between the surface of the first reflective structure facing the light-emitting surface of the display panel and the substrate is less than the distance between the surface of the light-emitting device facing the light-emitting surface of the display panel and the substrate.

[0016] In one implementation of the first aspect, a pixel unit includes two light-emitting devices with different light-emitting colors; in two adjacent pixel regions in the first direction, the pixel unit in one region includes a first-color light-emitting device and a second-color light-emitting device, and the pixel unit in the other region includes a second-color light-emitting device and a third-color light-emitting device.

[0017] In one implementation of the first aspect, the display panel includes a light guide structure, at least a portion of which is located on the side of the pixel unit facing the light-emitting surface of the display panel; in the same pixel region, along the thickness direction of the display panel, the light guide structure covers a second color light-emitting device and at least a portion of a first reflective structure; in the first direction, a first color light-emitting device or a third color light-emitting device is included between two adjacent light guide structures.

[0018] Secondly, embodiments of this application provide a display device, including a display panel as provided in the first aspect.

[0019] In this embodiment, a first reflective structure is provided to surround at least a portion of the light-emitting devices in the pixel unit. In addition to the light emitted directly from the light-emitting surface of the display panel, at least a portion of the light emitted from other directions can illuminate or be reflected onto the first reflective structure. This allows the light to be reflected out by the first reflective structure and ultimately emitted from the light-emitting surface of the display panel. This increases the light intensity and range of the light-emitting devices on the light-emitting surface of the display panel, thereby increasing the light-emitting area of ​​the pixel unit. This, in turn, helps to reduce the black area between the light-emitting areas of adjacent pixel units, ultimately improving the display quality of the display panel and enhancing the user's viewing experience.

[0020] Furthermore, since the second region surrounds at least part of the first region, light-emitting devices with different light-emitting colors in the first region can share the first reflection structure in the second region, which helps to ensure the mixing effect of different colors of light emitted by the light-emitting devices in the pixel unit, thereby helping to avoid polarization problems in the display panel.

These terms are only used to distinguish regions, reflective structures, scattering particles, etc., from each other. For example, without departing from the scope of the embodiments of this application, a first region may also be referred to as a second region, and similarly, a second region may also be referred to as a first region.

[0043] Through meticulous and in-depth research, the applicant in this case has provided a solution to the problems existing in the prior art.

[0044] Figure 1 This is a schematic diagram of a display panel provided in an embodiment of this application. Figure 2 This is a schematic diagram of yet another display panel provided in an embodiment of this application. Figure 3 for Figure 1 , Figure 2 A schematic diagram of a medium pixel unit. Figure 4 for Figure 1 , Figure 2 A schematic diagram of two adjacent pixel units. Figure 5 This is a partial structural diagram of a display panel provided in an embodiment of this application.

[0045] This application embodiment provides a display panel 01, combined with... Figure 1 , Figure 3 and Figure 4 ,or Figure 2 , Figure 3 and Figure 4 As shown, the display panel 01 includes multiple pixel regions AA, each including a first region A1 and a second region A2. The first region A1 includes pixel units 10, and each pixel unit 10 includes at least two light-emitting devices 101 with different emitted colors. For example, the light-emitting device 101 can be a micro-LED.

[0046] Optionally, such as Figure 3As shown, the pixel unit 10 includes three light-emitting devices 101 with different light-emitting colors. These three devices 101 include a first-color light-emitting device 1011, a second-color light-emitting device 1012, and a third-color light-emitting device 1013. Specifically, the first-color light-emitting device 1011 can be a red light-emitting device, the second-color light-emitting device 1012 can be a green light-emitting device, and the third-color light-emitting device 1013 can be a blue light-emitting device. The light emitted by the red, green, and blue light-emitting devices can be mixed to form white light. By controlling the brightness ratio among the various light-emitting devices 101, full-color display of the display panel 01 can be achieved.

[0047] Optionally, such as Figure 4 As shown, pixel unit 10 includes two light-emitting devices 101 with different emitting colors. In two adjacent pixel units 10, one includes a first-color light-emitting device 1011 and a second-color light-emitting device 1012, while the other includes a second-color light-emitting device 1012 and a third-color light-emitting device 1013. The first-color light-emitting device 1011 can be a red light-emitting device, the second-color light-emitting device 1012 can be a green light-emitting device, and the third-color light-emitting device 1013 can be a blue light-emitting device. When the display panel 01 emits light, the red and blue light-emitting devices can be shared by two adjacent pixel units 10. Full-color display of the display panel 01 can be achieved by controlling the brightness ratio between each light-emitting device 101.

[0048] Please continue to refer to this. Figure 1 and Figure 2 The second region A2 surrounds at least a portion of the first region A1, and the second region A2 includes a first reflective structure 20. That is, in the pixel region AA, the first region A1 can be completely surrounded by the second region A2, or the second region A2 can partially surround the first region A1. Of course, the first reflective structure 20 in the second region A2 can also surround at least a portion of the first region A1.

[0049] For example, such as Figure 1 As shown, the first region A1 can be located in the middle of the pixel region AA, and the second region A2 surrounds the entire first region A1.

[0050] For example Figure 2 As shown, the first region A1 can be located at the edge of the pixel region AA, and the second region A2 surrounds part of the first region A1.

[0051] Among them, combined Figure 5 As shown, the first reflective structure 20 surrounds at least a portion of the light-emitting device 101 in the pixel unit 10. That is, the first reflective structure 20 can be disposed around the light-emitting device 101.

[0052] It is understandable that in the display panel 01, the light emitted by the light-emitting device 101 will be emitted in multiple directions. Some light can be emitted directly from the light-emitting surface of the display panel 01, but a lot of light will be absorbed by the structure in the display panel 01, resulting in a small light emission range of the light-emitting device 101 on the light-emitting surface of the display panel 01.

[0053] In the embodiments of this application, such as Figure 5 As shown, by setting the first reflective structure 20 around at least a portion of the light-emitting devices 101 in the pixel unit 10, at least a portion of the light emitted by the light-emitting devices 101, except for the light emitted directly from the light-emitting surface of the display panel 01, can be irradiated by or reflected onto the first reflective structure 20. Thus, the light can be reflected out by the first reflective structure 20 and finally emitted from the light-emitting surface of the display panel 01. This is beneficial to increasing the light intensity and range of the light-emitting devices 101 on the light-emitting surface of the display panel 01, that is, to increasing the light-emitting area of ​​the pixel unit 10. This is beneficial to reducing the black area between the light-emitting areas of adjacent pixel units 10, thereby improving the display quality of the display panel 01 and enhancing the user's viewing experience.

[0054] Furthermore, since the second region A2 surrounds at least part of the first region A1, the light-emitting devices 101 with different light-emitting colors in the first region A1 can share the first reflective structure 20 in the second region A2, which is beneficial to ensuring the mixing effect of different colored light emitted by the light-emitting devices 101 in the pixel unit 10, thereby helping to avoid the polarization problem of the display panel 01.

[0055] Figure 6 This is a partial structural diagram of another display panel provided in an embodiment of this application. Figure 7 This is a partial structural schematic diagram of another display panel provided in an embodiment of this application.

[0056] In one embodiment of this application, the display panel 01 includes a plurality of light guide structures 30, which may be located in the pixel region AA, and at least some of the light guide structures 30 are located on the side of the pixel unit 10 facing the light-emitting surface of the display panel 01.

[0057] Along the thickness direction Z of the display panel 01, the light guide structure 30 overlaps at least partially with the pixel unit 10 and the first reflective structure 20.

[0058] Optionally, such as Figure 6 As shown, along the thickness direction Z of the display panel 01, the light guide structure 30 covers the pixel unit 10 and the first reflective structure 20. The light guide structure 30 can be conformally attached to the surfaces of the pixel unit 10 and the first reflective structure 20.

[0059] Optionally, such as Figure 7 As shown, along the thickness direction Z of the display panel 01, the light guide structure 30 covers the pixel unit 10 and part of the first reflective structure 20.

[0060] In this embodiment, the light guide structure 30 can increase the mixing distance of the light emitted by the light-emitting device 101 in the pixel unit 10, which is beneficial to improving the mixing effect of different colors of light emitted by the light-emitting device 101 in the pixel unit 10, thereby further ensuring the display quality of the display panel 01.

[0061] In one implementation of this application, the light guide structure 30 can be a transparent structure.

[0062] In one embodiment of this application, such as Figure 7 As shown, the first reflective structure 20 between at least two partially adjacent pixel units 10 is interconnected.

[0063] For example Figure 7 As shown, the multiple pixel regions AA include an adjacent first pixel region AA1 and a second pixel region AA2, and the first reflection structure 20 between the pixel unit 10 in the first pixel region AA1 and the pixel unit 10 in the second pixel region AA2 is connected together.

[0064] During the fabrication process, the first reflective structure 20 between two adjacent pixel units 10 can be integrally formed.

[0065] In this embodiment, the first reflective structure 20 between two adjacent pixel units 10 is connected to each other, which can increase the area of ​​the first reflective structure 20 in the display panel 01. This is beneficial to reflect as much light emitted by the pixel unit 10 as possible to the light-emitting surface of the display panel 01, which is beneficial to further reduce the black area when the display panel 01 emits light and improve the user's viewing experience.

[0066] Please continue to refer to this. Figure 7 In one embodiment of this application, the light guide structure 30 in the display panel 01 is a discontinuous structure.

[0067] In other words, in the display panel 01, the light guide structure 30 is not arranged on the entire surface, and there are gaps between adjacent light guide structures 30.

[0068] Optionally, the light guide structure 30 is located in the pixel region AA, and the light guide structure 30 is set in a one-to-one correspondence with the pixel unit 10.

[0069] In this embodiment, the light guide structure 30 is set to be a discontinuous structure, which helps to avoid color mixing of light emitted from different pixel units 10 when passing through the light guide structure 30.

[0070] Figure 8 This is a partial structural schematic diagram of another display panel provided in an embodiment of this application.

[0071] Furthermore, in one embodiment of this application, such as Figure 8 As shown, the pixel unit 10 includes three light-emitting devices 101 with different light-emitting colors.

[0072] For example, such as Figure 8 As shown, the pixel unit 10 includes a first color light-emitting device 1011, a second color light-emitting device 1012, and a third color light-emitting device 1013. The first color light-emitting device 1011 can be a red light-emitting device, the second color light-emitting device 1012 can be a green light-emitting device, and the third color light-emitting device 1013 can be a blue light-emitting device.

[0073] The display panel 01 also includes a light-absorbing structure 40, which is located between adjacent light-guiding structures 30.

[0074] Optionally, the light-absorbing structure 40 is a black structure.

[0075] In this embodiment, a light-absorbing structure 40 is provided between adjacent light guide structures 30, which can prevent the light emitted by the overlapping pixel units 10 of the light guide structures 30 from being transmitted to the adjacent pixel area AA. This helps to further avoid the problem of color mixing of the light emitted by adjacent pixel units 10, thereby helping to ensure the display quality of the display panel 01.

[0076] Figure 9 This is a partial structural schematic diagram of another display panel provided in an embodiment of this application.

[0077] In one embodiment of this application, such as Figure 9 As shown, the light guide structure 30 includes a plurality of first scattering particles 31.

[0078] It is understandable that scattering particles can change the direction of light transmission, causing light to be emitted in multiple directions.

[0079] In this embodiment, by providing a first scattering particle 31 in the light guide structure 30, the scattering of light emitted by the light-emitting device 101 in the light guide structure 30 can be increased, which is beneficial to further improve the mixing effect of different colors of light emitted by the light-emitting device 101 in the pixel unit 10.

[0080] In addition, the arrangement of the first scattering particle 31 can increase the emission range of the light emitted by the pixel unit 10 on the light-emitting surface of the display panel 01, which is conducive to further reducing the black area between the light-emitting areas of adjacent pixel units 10 and improving the user's viewing experience.

[0081] In one implementation of the embodiments of this application, please continue to refer to Figure 9 The light guide structure 30 includes a first part 30A located in the first region A1 and a second part 30B located in the second region A2. Along the thickness direction Z of the display panel 01, the first part 30A overlaps at least partially with the pixel unit 10, and the second part 30B overlaps at least partially with the first reflective structure 20.

[0082] In the first part 30A, the concentration of the first scattering particle 31 is greater than that in the second part 30B.

[0083] It is understandable that, since pixel unit 10 is located in the first region A1, the amount of light emitted from the first region A1 is usually greater than the amount of light emitted from the second region A2.

[0084] In this embodiment, the concentration of the first scattering particles 31 in the first part 30A is set to be greater than the concentration of the first scattering particles 31 in the second part 30B. Therefore, the scattering ability of the first part 30A to scatter light is greater than that of the second part 30B to scatter light. This is beneficial to reducing the difference between the number of light rays emitted from the first region A1 and the number of light rays emitted from the second region A2, thereby reducing the brightness difference between the first region A1 and the second region A2 in the pixel region AA, and thus improving the brightness uniformity of the display panel 01.

[0085] Figure 10 This is a partial structural schematic diagram of another display panel provided in an embodiment of this application.

[0086] like Figure 10 As shown, in one embodiment of this application, the display panel 01 further includes a second reflective structure 50, which is located on the side of the pixel unit 10 facing the light-emitting surface of the display panel 01.

[0087] Specifically, the second reflective structure 50 can be located on the side of the light guide structure 30 facing the light-emitting surface of the display panel 01.

[0088] Along the thickness direction Z of the display panel 01, the second reflective structure 50 overlaps at least partially with the pixel unit 10.

[0089] Optionally, the second reflective structure 50 covers the pixel unit 10 along the thickness direction Z of the display panel 01. That is, the second reflective structure 50 covers multiple light-emitting devices 101 in the pixel unit 10.

[0090] For further information, please continue to refer to [link / reference]. Figure 10Along the thickness direction Z of the display panel 01, the second reflective structure 50 partially overlaps with the first reflective structure 20. When the second reflective structure 50 needs to cover the pixel unit 10, considering the manufacturing process and error issues, setting the second reflective structure 50 to partially overlap with the first reflective structure 20 can ensure the effectiveness of the second reflective structure 50 in covering the pixel unit 10.

[0091] In this embodiment, the second reflective structure 50 is configured to overlap at least partially with the pixel unit 10. In this case, the monochromatic light emitted by at least some of the light-emitting devices 101 in the pixel unit 10 will not be emitted directly, but will be reflected by the second reflective structure 50 into the light guide structure 30, where it will be fully mixed with the monochromatic light emitted by other light-emitting devices 101 in the pixel unit 10, and then emitted after continuous reflection and refraction.

[0092] The embodiments of this application can avoid the direct emission of monochromatic light and can make the light emitted by the light-emitting device 101 in the pixel unit 10 more fully mixed, which helps to prevent users from discovering the monochromatic light in the pixel unit 10 when observing the display panel 01 at close range, thereby improving the user's viewing experience.

[0093] Figure 11 This is a partial structural schematic diagram of another display panel provided in an embodiment of this application.

[0094] In one embodiment of this application, such as Figure 11 As shown, the display panel 01 also includes a second scattering particle 32, which is attached to the surface of the light guide structure 30 facing the light emitting surface of the display panel 01.

[0095] When the light emitted by the light-emitting device 101 exits from the light guide structure 30 toward the light-emitting surface of the display panel 01, it will illuminate the second scattering particle 32, thereby causing further scattering.

[0096] In this embodiment, the arrangement of the second scattering particle 32 can further enhance the scattering of light, which is beneficial to further increase the light emission intensity and range of the light-emitting device 101 on the light-emitting surface of the display panel 01, that is, to further increase the light-emitting area of ​​the pixel unit 10, thereby reducing the black area between the light-emitting areas of adjacent pixel units 10 and further improving the user's viewing experience.

[0097] like Figures 5-11 As shown, in one embodiment of this application, the display panel 01 includes a substrate P, and the first reflective structure 20 and the pixel unit 10 are located on the same side of the substrate P;

[0098] The distance between the surface of the first reflective structure 20 facing the light-emitting surface of the display panel 01 and the substrate P is less than the distance between the surface of the light-emitting device 101 facing the light-emitting surface of the display panel 01 and the substrate P.

[0099] For example, such as Figure 11 As shown, the first reflective structure 20 includes a first surface 20A, which is the surface of the first reflective structure 20 facing the light-emitting surface of the display panel 01. The distance between the first surface 20A and the substrate P is d1. The light-emitting device 101 includes a second surface 101A, which is the surface of the light-emitting device 101 facing the light-emitting surface of the display panel 01. The distance between the second surface 101A and the substrate P is d2, where d1 < d2.

[0100] In the embodiments of this application, such as Figure 11 As shown, by setting the distance between the surface of the first reflective structure 20 facing the light-emitting surface of the display panel 01 and the substrate P to be less than the distance between the surface of the light-emitting device 101 facing the light-emitting surface of the display panel 01 and the substrate P, it can be ensured that at least part of the side light emission (i.e., wide-viewing-angle light emission) of the light-emitting device 101 can be emitted normally. Moreover, according to the principle of light reflection, after the side light emission of the light-emitting device 101 illuminates the first reflective structure 20, it can also be reflected by the first reflective structure 20 to the light-emitting surface of the display panel 01. This is beneficial to ensure that the light-emitting device 101 has a large light emission range on the light-emitting surface of the display panel 01, that is, it is beneficial to ensure that the pixel unit 10 has a large light-emitting area.

[0101] Figure 12 This is a partial structural schematic diagram of another display panel provided in an embodiment of this application.

[0102] In one embodiment of this application, such as Figure 12 As shown, pixel unit 10 includes two light-emitting devices 101 with different light-emitting colors. In two adjacent pixel regions AA in the first direction X, one pixel unit 10 includes a first-color light-emitting device 1011 and a second-color light-emitting device 1012, while the other pixel unit 10 includes a second-color light-emitting device 1012 and a third-color light-emitting device 1013. The first direction X may intersect with the thickness direction Z of the display panel 01.

[0103] Optionally, the first color light-emitting device 1011 is a red light-emitting device, the second color light-emitting device 1012 is a green light-emitting device, and the third color light-emitting device 1013 is a blue light-emitting device. The light emitted by the red, green, and blue light-emitting devices can be mixed to form white light. By controlling the brightness ratio between the red, green, and blue light-emitting devices, full-color display of the display panel 01 can be achieved.

[0104] When displayed on the display panel 01, the pixel units 10 in two adjacent pixel areas AA in the first direction X can share the first color light-emitting device 1011 and the third color light-emitting device 1013.

[0105] For example, such as Figure 12 As shown, the multiple pixel regions AA include a first pixel region AA1 and a second pixel region AA2 that are adjacent in the first direction X. The pixel unit 10 of the first pixel region AA1 includes a first color light-emitting device 1011 and a second color light-emitting device 1012. The pixel unit 10 of the second pixel region AA2 includes a second color light-emitting device 1012 and a third color light-emitting device 1013.

[0106] During the display process of the display panel 01, when the pixel unit 10 in the first pixel area AA1 needs to be displayed, the first color light-emitting device 1011 and the second color light-emitting device 1012 in the first pixel area AA1 emit light, and at the same time, the third color light-emitting device 1013 in the second pixel area AA2 also emits light to satisfy the full-color display of the display panel 01.

[0107] When the pixel unit 10 in the second pixel area AA2 needs to be displayed, the second color light-emitting device 1012 and the third color light-emitting device 1013 in the second pixel area AA2 emit light, and at the same time, the first color light-emitting device 1011 in the first pixel area AA1 also emits light, so as to satisfy the full-color display of the display panel 01.

[0108] In this embodiment of the application, the light-emitting devices 101 in two adjacent pixel regions AA in the first direction X can be surrounded by the first reflective structure 20. The light emitted by the light-emitting devices 101 in the two pixel regions AA can also be reflected by the first reflective structure 20 to the light-emitting surface of the display panel 01, which is beneficial to increase the area of ​​the light-emitting area in the display panel 01, that is, to reduce the black area between adjacent light-emitting areas, thereby improving the user's viewing experience.

[0109] Figure 13 This is a schematic diagram of yet another display panel provided in an embodiment of this application. Figure 14 for Figure 13 A schematic diagram of a partial structure of the display panel along the NN' tangent.

[0110] Combination Figure 13 and Figure 14 As shown, in one implementation of this application embodiment, the display panel 01 further includes a light guide structure 30, at least a portion of which is located on the side of the pixel unit 10 facing the light-emitting surface of the display panel 01. The light guide structure 30 may be located in pixel region AA and is used to mix different colors of light emitted by the light-emitting device 101 in the pixel unit 10.

[0111] Within the same pixel region AA, along the thickness direction Z of the display panel 01, the light guide structure 30 covers the second color light-emitting device 1012 and at least a portion of the first reflective structure 20. In the first direction X, adjacent light guide structures 30 include either a first color light-emitting device 1011 or a third color light-emitting device 1013.

[0112] In other words, along the first direction X, the first color light-emitting device 1011 can be located between two adjacent light guide structures 30, and the third color light-emitting device 1013 can also be located between two adjacent light guide structures 30. Of course, the first color light-emitting device 1011 and the third color light-emitting device 1013 can be located between different adjacent light guide structures 30.

[0113] For example, such as Figure 14 As shown, the plurality of pixel regions AA include a first pixel region AA1, a second pixel region AA2 and a third pixel region AA3 that are sequentially adjacent along the first direction X. The pixel unit 10 of the first pixel region AA1 includes a first color light-emitting device 1011 and a second color light-emitting device 1012. The pixel unit 10 of the second pixel region AA2 includes a second color light-emitting device 1012 and a third color light-emitting device 1013. The pixel unit 10 of the third pixel region AA3 includes a first color light-emitting device 1011 and a second color light-emitting device 1012.

[0114] Along the thickness direction Z of the display panel 01, the light guide structure 30 located in the first pixel region AA1 covers the second color light-emitting device 1012 and at least part of the first reflection structure 20 in the first pixel region AA1, the light guide structure 30 located in the second pixel region AA2 covers the second color light-emitting device 1012 and at least part of the first reflection structure 20 in the second pixel region AA2, and the light guide structure 30 located in the third pixel region AA3 covers the second color light-emitting device 1012 and at least part of the first reflection structure 20 in the third pixel region AA3.

[0115] The third color light-emitting device 1013 in the second pixel region AA2 is located between the light guide structure 30 in the first pixel region AA1 and the light guide structure 30 in the second pixel region AA2, and the first color light-emitting device 1011 in the third pixel region AA3 is located between the light guide structure 30 in the second pixel region AA2 and the light guide structure 30 in the third pixel region AA3.

[0116] In this implementation, when the first color light-emitting device 1011, the second color light-emitting device 1012, and the third color light-emitting device 1013 in two adjacent pixel regions AA emit light, the light emitted by these light-emitting devices can be mixed and emitted through the light guide structure 30 of their respective pixel regions AA, and can also be mixed and emitted through the light guide structure 30 adjacent to them. In addition, the light emitted by these light-emitting devices can also illuminate or be reflected onto the first reflection structure 20 in multiple pixel regions AA, and be finally reflected by these first reflection structures 20 to the light-emitting surface of the display panel 01. This helps to increase the area of ​​the light-emitting region in the display panel 01, that is, it can reduce the black area between adjacent light-emitting regions, thereby improving the user's viewing experience.

[0117] Figure 15 This is a schematic diagram of a display device provided in an embodiment of this application.

[0118] like Figure 15 As shown, this application embodiment provides a display device 02, which includes a display panel 01 as provided in the above embodiment. The display device 02 provided in this application embodiment can be a mobile phone. In addition, the display device 02 provided in this application embodiment can also be an electronic device such as a computer, television, or vehicle display.

[0119] In the display device 02, a first reflective structure 20 is provided to surround at least a portion of the light-emitting devices 101 in the pixel unit 10. Then, among the light emitted by the light-emitting devices 101, besides those directly emitted from the light-emitting surface of the display panel 01, at least a portion of the light from other directions can illuminate or be reflected onto the first reflective structure 20, and thus be reflected out by the first reflective structure 20 and ultimately emitted from the light-emitting surface of the display panel 01. This is beneficial for increasing the light intensity and range of the light-emitting devices 101 on the light-emitting surface of the display panel 01, i.e., for increasing the light-emitting area of ​​the pixel unit 10, thereby reducing the black area between the light-emitting areas of adjacent pixel units 10, and further improving the display quality of the display device 02 and enhancing the user's viewing experience.

[0120] Furthermore, since the second region A2 surrounds at least part of the first region A1, the light-emitting devices 101 with different light-emitting colors in the first region A1 can share the first reflective structure 20 in the second region A2, which is beneficial to ensuring the mixing effect of different colored light emitted by the light-emitting devices 101 in the pixel unit 10, thereby helping to avoid the polarization problem of the display panel 01.

[0121] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
