Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display panel and a display device. BACKGROUND

[0002] Micro-Light Emitting Diode (Micro-LED) display panel has the advantages of high brightness, high contrast, wide color gamut and wider viewing angle display, and has wide application in outdoor fields such as wearable devices and vehicle-mounted devices.

[0003] In the related art, each micro light emitting diode in the micro light emitting diode display panel emits a different color from the adjacent micro light emitting diode, and the color emitted by any two adjacent micro light emitting diodes is prone to color mixing, resulting in impure display chroma of the display panel, reduced display color gamut, and poor display effect of the display panel. SUMMARY

[0004] Therefore, it is necessary to propose a display panel and a display device to solve the problem of poor display effect of the display panel.

[0005] A display panel comprises:

[0006] a substrate;

[0007] a plurality of light emitting devices arranged on one side of the substrate, and arranged into a plurality of device rows along a first direction and a plurality of device columns along a second direction; the first direction, the second direction and the thickness direction of the substrate intersect with each other;

[0008] a first barrier layer arranged on one side of the substrate; the first barrier layer comprises a plurality of first barrier portions,

[0009] the plurality of first barrier portions and the plurality of device columns are alternately arranged along the first direction.

[0010] The present application also proposes a display device comprising the display panel.

[0011] The display panel and the display device in the embodiment have the following advantages. The first blocking parts and the plurality of device columns are arranged alternately along the first direction. Thus, a first blocking part is arranged between any two adjacent device columns along the first direction. The first blocking part between each device column and the adjacent device column separates the device column from the adjacent device column. When the light emitting devices of any two adjacent device columns emit light of different colors, the light emitted by the light emitting devices of each device column is blocked by the first blocking part between the device column and the adjacent device column during irradiation to the light emitting devices of the adjacent device column. The blocking of the first blocking part reduces the risk of the light emitted by the light emitting devices of each device column irradiating to the light emitting devices of the adjacent device column, thereby preventing the light emitted by the light emitting devices of each device column from mixing with the light emitted by the light emitting devices of the adjacent device column. The light emitted by the light emitting devices of the two adjacent device columns is less likely to mix, thereby avoiding the display panel having impure display color and reduced display color gamut due to the light emitted by the light emitting devices of the two adjacent device columns mixing.

[0012] In conclusion, the display panel and the display device in the embodiment can improve the display color and the display color gamut of the display panel, improve the contrast of the display panel, and enhance the display effect of the display panel. BRIEF DESCRIPTION OF DRAWINGS

[0044] Please refer to Figure 1 With Figure 2 , Figure 1 A structural schematic diagram of a display panel 10 in an embodiment of the present application is shown. The display panel 10 provided by an embodiment of the present application includes a substrate 100, a plurality of light emitting devices 200, and a first barrier layer 300. The plurality of light emitting devices 200 are arranged on one side of the substrate 100, and are arranged into a plurality of device rows M1 along a first direction V1 and a plurality of device columns M2 along a second direction V2; the first direction V1, the second direction V2 and a thickness direction V3 of the substrate 100 intersect with each other. The first barrier layer 300 is arranged on one side of the substrate 100; the first barrier layer 300 includes a plurality of first barrier portions 310, and the plurality of first barrier portions 310 and the plurality of device columns M2 are alternately arranged along the first direction V1.

[0045] The display panel 10 in the embodiment can improve the display chroma and the display color gamut of the display panel 10, improve the contrast of the display panel 10, and enhance the display effect of the display panel 10.

[0046] The display panel 10 in the embodiment can improve the display chroma and the display color gamut of the display panel 10, improve the contrast of the display panel 10, and enhance the display effect of the display panel 10.

[0047] Please refer to Figure 1 With Figure 2 In some embodiments, the first blocking part 310 includes a plurality of first blocking sub-parts 311. The plurality of first blocking sub-parts 311 in at least one first blocking part 310 are arranged corresponding to a plurality of light emitting devices 200 in the device column M2 adjacent to the first blocking part 310, and the light emitting device 200 is located on one side of the corresponding first blocking sub-part 311 along the first direction V1.

[0048] The display panel 10 in the embodiment can improve the display chroma and the display color gamut of the display panel 10, improve the contrast of the display panel 10, and enhance the display effect of the display panel 10.

[0046] The display panel 10 in the embodiment can improve the display chroma and the display color gamut of the display panel 10, improve the contrast of the display panel 10, and enhance the display effect of the display panel 10.

[0047] Please refer to Figure 1 With Figure 2 In some embodiments, the first blocking part 310 includes a plurality of first blocking sub-parts 311. The plurality of first blocking sub-parts 311 in at least one first blocking part 310 are arranged corresponding to a plurality of light emitting devices 200 in the device column M2 adjacent to the first blocking part 310, and the light emitting device 200 is located on one side of the corresponding first blocking sub-part 311 along the first direction V1.

[0048] The display panel 10 in the embodiment can improve the display chroma and the display color gamut of the display panel 10, improve the contrast of the display panel 10, and enhance the display effect of the display panel 10.

[0049] In some embodiments, the plurality of first blocking sub-parts 311 in each first blocking part 310 are arranged corresponding to the plurality of light emitting devices 200 in the device column M2 adjacent to the first blocking part 310.

[0050] Referring to Figure 1 In some embodiments, the display panel 10 comprises a light dispersion layer 400 arranged on the side of the first blocking layer 300 away from the substrate 100. The light dispersion layer 400 comprises a plurality of light dispersion parts 410 arranged corresponding to the plurality of light emitting devices 200, the light dispersion part 410 is arranged on the side of the corresponding light emitting device 200 away from the substrate 100, and the orthographic projection of the light dispersion part 410 on the substrate 100 at least partially overlaps with the projection of the corresponding light emitting device 200 on the substrate 100.

[0051] The display panel 10 in the embodiment can reduce the visual angle of the light emitted by the light emitting device 200 in the display panel 10 due to the blocking of the first blocking part 310 to the light emitted by the light emitting device 200 in the adjacent device column M2. By arranging the light dispersion part 410 on the side of the corresponding light emitting device 200 away from the substrate 100, the light emitted by each light emitting device 200 can be irradiated to the light dispersion part 410 corresponding to the light emitting device 200 in the direction close to the light dispersion part 410. It should be emphasized that the light emitted by each light emitting device 200 will be scattered in the corresponding light dispersion part 410 after being irradiated to the light dispersion part 410, and then scattered from the side of the light dispersion part 410 away from the substrate 100.

[0052] Since the light dispersion part 410 can scatter the light emitted by the light emitting device 200, the visual angle of the light entering the light dispersion part 410 from the side of the light dispersion part 410 close to the substrate 100 is smaller than the visual angle of the light exiting the light dispersion part 410 from the side of the light dispersion part 410 away from the substrate 100. That is, the light dispersion part 410 can increase the visual angle of the light emitted by the light emitting device 200 and reduce the influence of the first blocking part 310 on the visual angle of the light emitted by the light emitting device 200. In summary, by arranging the first blocking part 310 and the light dispersion part 410, the color mixing of the light emitted by the adjacent two light emitting devices 200 can be avoided, and the visual angle of the light emitted by the light emitting device 200 can be ensured.

[0053] Referring to Figure 1 With Figure 2In some embodiments, the light dispersion part 410 is located within the range of the normal projection of the light emitting device 200 on the substrate 100.

[0054] In the display panel 10 of the present embodiment, the normal projection of the light dispersion part 410 on the substrate 100 is located within the range of the normal projection of the light emitting device 200 on the substrate 100, so that the light emitted by the light emitting device 200 can be collected by the light dispersion part 410, and the light emitted by the light emitting device 200 can be scattered in the light dispersion part 410.

[0055] Please refer to Figure 1 In some embodiments, the light dispersion part 410 includes an optical adhesive layer 411 and scattering particles (not shown in the figure), and the scattering particles are doped in the optical adhesive layer 411.

[0056] In the display panel 10 of the present embodiment, the light emitted by each light emitting device 200 is irradiated to the optical adhesive layer 411 of the light dispersion part 410 corresponding to the light emitting device 200 in the direction close to the light dispersion part 410. After the light emitted by each light emitting device 200 is irradiated into the optical adhesive layer 411 of the light dispersion part 410, the light is diffusely reflected under the action of the scattering particles doped in the optical adhesive layer 411 of the light dispersion part 410, and then scattered out from the side of the light dispersion part 410 away from the substrate 100. By doping the scattering particles in the optical adhesive layer 411, the scattering effect of the light dispersion part 410 can be improved, and the visual angle of the light scattered out from the side of the light dispersion part 410 away from the substrate 100 can be increased.

[0057] Please refer to Figure 3 With Figure 4 In some embodiments, the display panel 10 includes a second blocking layer 500, which is arranged on the side of the first blocking layer 300 away from the substrate 100. The second blocking layer 500 includes a plurality of second blocking parts 510, which are arranged corresponding to the plurality of device rows M1; the second blocking part 510 is provided with a plurality of first through holes 511, and the plurality of first through holes 511 on the second blocking part 510 are arranged corresponding to the plurality of light emitting devices 200 in the corresponding device row M1, and the light dispersion part 410 corresponding to the light emitting device 200 is located in the first through hole 511 corresponding to the light emitting device 200.

[0058] The display panel 10 in this embodiment, the light dispersion part 410 in any two adjacent first through holes 511 on the second blocking part 510 will be separated by the part of the second blocking part 510 between the two first through holes 511. The light scattered by the light dispersion part 410 in each first through hole 511 can only be emitted in the direction away from the substrate 100 along the axis direction of the first through hole 511 under the blocking of the second blocking part 510 between the first through hole 511 and the adjacent first through hole 511, and cannot be emitted to the light dispersion part 410 in the adjacent first through hole 511 of the first through hole 511. In this way, the risk of color mixing of the light scattered by the light dispersion parts 410 in the two adjacent first through holes 511 can be reduced.

[0059] Referring to Figure 1 , Figure 5 and Figure 6 In some embodiments, the display panel 10 includes a color filter layer 600, which is arranged on the side of the second blocking layer 500 away from the substrate 100. The color filter layer 600 includes a plurality of color resistances 610, which are arranged correspondingly to the plurality of light dispersion parts 410. The orthographic projection of the first through hole 511 corresponding to the light dispersion part 410 on the substrate 100 overlaps the orthographic projection of the color resistance 610 corresponding to the light dispersion part 410 on the substrate 100.

[0060] The display panel 10 in this embodiment, the light emitted by each light emitting device 200 will be scattered by the light dispersion part 410 corresponding to the light emitting device 200 after being emitted into the corresponding light dispersion part 410, and then emitted from the side of the corresponding light dispersion part 410 away from the substrate 100 and through a color resistance 610. By arranging the orthographic projection of the first through hole 511 corresponding to the light dispersion part 410 on the substrate 100 to overlap the orthographic projection of the color resistance 610 corresponding to the light dispersion part 410 on the substrate 100, it can be ensured that the color resistance 610 corresponding to each light dispersion part 410 filters the light scattered by the light dispersion part 410, so as to filter out the light of different colors from the light emitting device 200 corresponding to the light dispersion part 410, thereby improving the color saturation of the display panel 10.

[0061] Referring to Figure 1 , Figure 5 and Figure 6 In some embodiments, the orthographic projection of the first through hole 511 corresponding to the light dispersion part 410 on the substrate 100 is located within the range of the orthographic projection of the color resistance 610 corresponding to the light dispersion part 410 on the substrate 100.

[0062] The display panel 10 in the embodiment, the first through hole 511 corresponding to the light dispersion part 410 on the substrate 100 is located in the range of the normal projection of the color resistance 610 corresponding to the light dispersion part 410 on the substrate 100, thus, each color resistance 610 will not block the light scattered by the light dispersion part 410 corresponding to the color resistance 610, and the visual angle of the light scattered by the light dispersion part 410 can be ensured accordingly.

[0063] In some embodiments, the normal projection of the color resistance 610 on the substrate 100 is coincided with the normal projection of the corresponding light emitting device 200 on the substrate 100; or, the normal projection of the color resistance 610 on the substrate 100 is located in the range of the normal projection of the corresponding light emitting device 200 on the substrate 100.

[0064] Please refer to Figure 1 , Figure 5 and Figure 6 In some embodiments, the display panel 10 includes a third blocking layer 700, which is arranged on the side of the second blocking layer 500 away from the substrate 100. The third blocking layer 700 includes a plurality of third blocking parts 710, which are arranged corresponding to the plurality of second blocking parts 510, and the third blocking part 710 is arranged on the side of the corresponding second blocking part 510 away from the substrate 100; the third blocking part 710 is provided with a plurality of second through holes 711, and the plurality of second through holes 711 on the third blocking part 710 are arranged corresponding to the plurality of first through holes 511 on the corresponding second blocking part 510. The color resistance 610 corresponding to the light dispersion part 410 in the first through hole 511 is located in the second through hole 711 corresponding to the first through hole 511.

[0065] In the display panel 10 in the embodiment, the color resistance 610 in any two adjacent second through holes 711 on the third blocking part 710 is separated by the part of the third blocking part 710 between the two second through holes 711.

[0066] The light passing through the color resistance 610 in each second through hole 711 can only be emitted in the direction away from the substrate 100 along the axis direction of the second through hole 711 under the blocking of the part of the third blocking part 710 between the second through hole 711 and the adjacent second through hole 711, and cannot be emitted to the color resistance 610 in the adjacent second through hole 711 of the second through hole 711. Thus, the light passing through the color resistance 610 in the adjacent two second through holes 711 is less likely to cause color mixing.

[0067] Please refer to Figure 1 , Figure 5 and Figure 6In some embodiments, the color of the color resist 610 is the same as the light emitting color of the corresponding light emitting device 200. At least some of the light emitting devices 200 in the device row M1 and / or the device column M2 emit light rays of different colors from the adjacent light emitting devices 200.

[0068] In the display panel 10 in the present embodiment, since the color of each color resist 610 is the same as the light emitting color of the corresponding light emitting device 200, each color resist 610 can improve the color saturation of the light rays emitted by the light emitting device 200 corresponding to the color resist 610.

[0069] In some embodiments, each light emitting device 200 in the device row M1 and / or the device column M2 emits light rays of different colors from the adjacent light emitting devices 200.

[0070] In other embodiments, each light emitting device 200 in the device column M2 emits light rays of the same color as the adjacent light emitting devices 200.

[0071] In the present embodiment, since each light emitting device 200 in the device column M2 emits light rays of the same color as the adjacent light emitting devices 200, each device column M2 can only emit one color and can only display a pattern of one color.

[0072] Please refer to Figure 1 and Figure 2 In some embodiments, among the light emitting devices 200 in the device row M1, at least some of the light emitting devices 200 emit light rays of different colors from the remaining light emitting devices 200. And / or, among the light emitting devices 200 in the device column M2, at least some of the light emitting devices 200 emit light rays of different colors from the remaining light emitting devices 200.

[0073] In the display panel 10 in the present embodiment, since among the light emitting devices 200 in the device row M1, at least some of the light emitting devices 200 emit light rays of different colors from the remaining light emitting devices 200, the device row M1 can emit light rays of multiple different colors and display images of different colors. Similarly, the device column M2 can emit light rays of multiple different colors and display images of different colors.

[0074] In some embodiments, among the light emitting devices 200 in the device row M1, each light emitting device 200 emits light rays of a different color from the remaining light emitting devices 200.

[0075] In some embodiments, among the light emitting devices 200 in the device column M2, each light emitting device 200 emits light rays of a different color from the remaining light emitting devices 200.

[0076] Please refer to Figure 1 and Figure 2In some embodiments, the plurality of light emitting devices 200 in the device row M1 includes a plurality of first light emitting devices 210, a plurality of second light emitting devices 220, a plurality of third light emitting devices 230, and a plurality of fourth light emitting devices 240; the first light emitting devices 210, the second light emitting devices 220, the third light emitting devices 230, and the fourth light emitting devices 240 respectively emit light rays of different colors, and the fourth light emitting devices 240 emit white light.

[0077] The working process of the display panel 10 includes a first light emitting state in which one of the first light emitting devices 210, the second light emitting devices 220, the third light emitting devices 230, and the fourth light emitting devices 240 emit light at the same time; and / or, the working process of the display panel 10 includes a second light emitting state in which the first light emitting devices 210, the second light emitting devices 220, the third light emitting devices 230, and the fourth light emitting devices 240 emit light at the same time.

[0078] The display panel 10 in the embodiment displays a monochrome picture when the display panel 10 is in the first light emitting state, at which time one of the first light emitting devices 210, the second light emitting devices 220, the third light emitting devices 230, and the fourth light emitting devices 240 emit light rays at the same time, in the process of which the light rays emitted by the one of the first light emitting devices 210, the second light emitting devices 220, the third light emitting devices 230, and the fourth light emitting devices 240 form a monochrome picture,

[0079] The white light rays emitted by the fourth light emitting devices 240 enhance the monochrome picture to improve the brightness of the monochrome picture displayed by the display panel 10. When the display panel 10 is in the second light emitting state, the display panel 10 displays a color picture, at which time the first light emitting devices 210, the second light emitting devices 220, the third light emitting devices 230, and the fourth light emitting devices 240 emit light at the same time, in the process of which the light rays emitted by the first light emitting devices 210, the second light emitting devices 220, and the third light emitting devices 230 mix to form a color picture, and the white light rays emitted by the fourth light emitting devices 240 enhance the color picture to improve the brightness of the color picture displayed by the display panel 10.

[0080] As described above, the display panel 10 in the embodiment can improve the brightness of the display picture of the display panel 10 through the above-mentioned arrangement.

[0086] In the display panel 10 in the embodiment, when the number of the first blocking parts 310 is greater than the number of the device columns M2, at least one first blocking part 310 is arranged on each device column M2 along the opposite sides of the device column M2 in the first direction V1. Correspondingly, the light outside each device column M2 is difficult to irradiate to the light emitting devices 200 in the device column M2 from the opposite sides of the device column M2 in the first direction, and the light emitting devices 200 in each device column M2 can better avoid color mixing with other light.

[0087] Referring to Figure 1 In some embodiments, the display panel 10 comprises a planarization layer 800 and a bonding layer 900. The planarization layer 800 is arranged on the side of the substrate 100 close to the light emitting devices 200, the side of the light emitting devices 200 away from the substrate 100 and the side of the first blocking layer 300 away from the substrate 100; the planarization layer 800 wraps the surface of the light emitting devices 200; wherein the side of the planarization layer 800 away from the substrate 100 is parallel to the side of the substrate 100 close to the light emitting devices 200. The bonding layer 900 is arranged on the side of the planarization layer 800 away from the substrate 100; the light dispersion layer 400 is arranged on the side of the bonding layer 900 away from the substrate 100.

[0088] The display panel 10 in the embodiment, the planarization layer 800 is made of transparent material, the planarization layer 800 wraps the surface of the light emitting device 200, can protect the light emitting device 200, prevent the water vapor from the light emitting device 200 along the opposite sides of the second direction V2, the light emitting device 200 is eroded. In addition, by setting the side of the planarization layer 800 away from the substrate 100 parallel to the side of the substrate 100 close to the light emitting device 200, so as to form the adhesion layer 900 and other film layers on the side of the adhesion layer 900 away from the substrate 100 on the side of the planarization layer 800 away from the substrate 100.

[0089] In some embodiments, the display panel 10 includes a protective layer 1000, the protective layer 1000 is located on the side of the color film layer 600 and the third barrier layer 700 away from the substrate 100.

[0090] Please refer to Figure 11 , Figure 11 The structure of the display device 1 in the embodiment of the application is shown, and the application further provides a display device 1, which comprises a display panel 10.

[0091] The display device 1 in the embodiment, since the plurality of first blocking parts 310 and the plurality of device columns M2 are arranged alternately along the first direction V1, thus, a first blocking part 310 is arranged between any two device columns M2 adjacent along the first direction V1, and the first blocking part 310 between each device column M2 and the adjacent device column M2 can separate the device column M2 from the adjacent device column M2. Since the first blocking part 310 can separate the two adjacent device columns M2, thus, when the light emitting devices 200 of any two adjacent device columns M2 emit light of different colors respectively, the light emitted by the light emitting device 200 of each device column M2 in the two adjacent device columns M2 will be blocked by the first blocking part 310 between the device column M2 and the adjacent device column M2 in the process of irradiating the light emitting device 200 of the adjacent device column M2. Through the blocking of the first blocking part 310, the risk that the light emitted by the light emitting device 200 of each device column M2 irradiates the light emitting device 200 of the adjacent device column M2 can be reduced, so as to prevent the light emitted by the light emitting device 200 of each device column M2 from causing color mixing with the light emitted by the light emitting device 200 of the adjacent device column M2. By making the light emitted by the light emitting devices 200 of the two adjacent device columns M2 less likely to cause color mixing, the display panel 10 can be prevented from causing impure display color and reduced display color gamut due to color mixing of the light emitted by the light emitting devices 200 of the two adjacent device columns M2.

[0092] In conclusion, the display device 1 in the embodiment can improve the display chroma and display gamut of the display panel 10, improve the contrast of the display panel 10, and enhance the display effect of the display panel 10.
