[0029] Please refer to Figure 1 and Figure 2 As shown, Figure 1 This is a top view of the display panel provided in an embodiment of the present invention. Figure 2 For along Figure 1 A partial cross-sectional view along the AA direction, wherein the cross-section is perpendicular to the plane where the display panel is located.

[0030] Optionally, the display panel 100 is divided into a display area AA and a non-display area NA surrounding the display area AA. This is understandable. Figure 1The midpointed outline is used to indicate the boundary between the display area AA and the non-display area NA. The display area AA is the area of ​​the display panel used to display the image, and it typically includes multiple pixels sp arranged in an array. Each pixel sp includes a corresponding light-emitting element (e.g., a diode) and a control element (e.g., a thin-film transistor that constitutes the pixel driving circuit). The non-display area NA surrounds the display area AA and typically includes peripheral driving elements, peripheral traces, and a fan-out area.

[0031] Optionally, the display panel 100 includes an array substrate 120.

[0032] Optionally, the array substrate 120 includes a substrate 110.

[0033] Optionally, the substrate 110 may be formed of a polymeric material such as glass, polyimide (PI), polycarbonate (PC), polyethersulfone (PES), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyaryl compounds (PAR), or glass fiber reinforced plastic (FRP). The substrate 110 may be transparent, translucent, or opaque.

[0034] Optionally, the substrate 110 can be flexible or rigid. It should be noted that, in the embodiments of this application, the phrase "a certain film layer is located on a certain reference film layer" can be understood as being located "on the side of the reference film layer away from the substrate". Unless otherwise specified, "on" only indicates the orientation relationship and does not mean that the two film layers are necessarily adjacent or in contact.

[0035] Optionally, the array substrate 120 may also include a buffer layer (not shown) located on the substrate 110, which may cover the entire upper surface of the substrate 110.

[0036] Optionally, the array substrate 120 may also include pixel circuitry and a driving module for controlling the light-emitting element 130.

[0037] Specifically, the array substrate 120 includes multiple pixel circuits located in the display area AA and a driving module located in the non-display area NA. Optionally, the pixel circuits and the driving module are located on the side of the substrate 110 facing the display surface or touch surface of the display panel 100.

[0038] The array substrate 120 may also include a plurality of thin film transistors 210 and a pixel circuit composed of thin film transistors for controlling the light emission of the light-emitting element 130.

[0039] This invention describes the structure of a top-gate thin-film transistor as an example. The thin-film transistor layer 210 includes an active layer 211 located on a substrate 110. The active layer 211 can be made of amorphous silicon, polycrystalline silicon, or metal oxide, etc. When the active layer 211 is made of polycrystalline silicon, it can be formed using low-temperature amorphous silicon technology, that is, amorphous silicon material is melted by laser to form polycrystalline silicon material. In addition, various methods such as rapid thermal annealing (RTA), solid-state crystallization (SPC), excimer laser annealing (ELA), metal-induced crystallization (MIC), metal-induced lateral crystallization (MILC), or continuous lateral solidification (SLS) can also be used. The active layer 211 also includes a source region and a drain region formed by doping with N-type or P-type impurity ions, and a channel region between the source region and the drain region.

[0040] A gate insulating layer 212 is located on the active layer 211. The gate insulating layer 212 includes an inorganic layer such as silicon oxide or silicon nitride, and may include a single layer or multiple layers.

[0041] A gate 213 is located on the gate insulating layer 212. The gate 213 may comprise a single or multiple layers of gold (Au), silver (Ag), copper (Cu), nickel (Ni), platinum (Pt), palladium (Pd), aluminum (Al), molybdenum (MO), or chromium (Cr), or alloys such as aluminum (Al): neodymium (Nd) alloys and molybdenum (MO): tungsten (W) alloys.

[0042] An interlayer insulating layer 214 is located on the gate 213. The interlayer insulating layer 214 may be formed of an inorganic insulating layer such as silicon oxide or silicon nitride. Of course, in other alternative embodiments of the present invention, the interlayer insulating layer may be formed of an organic insulating material.

[0043] The source electrode and drain electrode are located on the interlayer insulating layer 214. The source electrode and drain electrode are electrically connected (or bonded) to the source region and drain region respectively through contact holes, which are formed by selectively removing the gate insulating layer 212 and the interlayer insulating layer 214.

[0044] The array substrate 120 may also include a passivation layer (not shown). Optionally, the passivation layer is located on the source and drain electrodes of the thin-film transistor 210. The passivation layer may be formed of an inorganic material such as silicon oxide or silicon nitride, or it may be formed of an organic material.

[0045] The array substrate 120 may further include a planarization layer 230. Optionally, the planarization layer 230 is located on the passivation layer. The planarization layer 230 includes an organic material such as acrylic, polyimide (PI) or benzocyclobutene (BCB), and has a planarization effect.

[0046] Optionally, the display panel 100 includes multiple pixels (sp).

[0047] Optionally, the pixel sp includes a light-emitting element 130.

[0048] Optionally, the light-emitting element 130 is located on one side of the array substrate 120 and is electrically connected to the array substrate 120.

[0049] Specifically, the light-emitting element 130 is located on the side of the array substrate 120 away from the substrate 110 and is electrically connected to the pixel circuit in the array substrate 120.

[0050] Optionally, the light-emitting element 130 is a micro light-emitting diode or a micro-LED. Using a micro-LED as the light-emitting element 130 can effectively improve the lifespan of the display panel, reduce the power consumption of the display panel, reduce the response time of the display panel, and increase the viewing angle of the display panel.

[0051] Optionally, at least two of the light-emitting elements 130 may be configured differently.

[0052] It should be noted that in this embodiment, the different arrangement of the light-emitting element 130 refers to the different degrees of tilt of the light-emitting element 130 relative to the plane of the display panel. This can avoid mutual interference between the light emitted by different pixel light-emitting elements 130.

[0053] The following embodiments of this application will be described using Micro-LED as an example of light-emitting element 130.

[0054] like Figure 3 As shown, Figure 3 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 1 Another local cross-sectional view in the AA direction.

[0055] Optionally, the size of the Micro-LED is less than 100μm.

[0056] Optionally, the light-emitting element 130 includes a first semiconductor layer, a quantum well layer, and a second semiconductor layer stacked together, with the quantum well layer located between the first and second semiconductor layers. The light-emitting element 130 also includes an electrode layer 103. Optionally, in this embodiment, the electrode layer 103 is located on the side of the light-emitting element 130 closer to the pixel circuit. The electrode layer 103 includes at least two electrodes; these two electrodes are respectively connected to the first semiconductor layer and the second semiconductor layer.

[0057] Optionally, the electrode layer 103 of the light-emitting element includes a first electrode and a second electrode, which are the positive and negative electrodes (i.e., N-pole and P-pole; also referred to as cathode and anode) of the light-emitting element, respectively. The first semiconductor layer is located on the side of the second semiconductor layer closest to the pixel circuit; the first electrode is located on the side of the first semiconductor layer closest to the pixel circuit, and the second electrode is located on the side of the second semiconductor layer closest to the pixel circuit.

[0058] Optionally, the light-emitting element 130 includes a light-emitting area 310 and a non-light-emitting area 320.

[0059] Optionally, the light-emitting region 310 includes a region where a first semiconductor layer, a quantum well layer, and a second semiconductor layer are stacked. The non-light-emitting region 320 includes a region where a second electrode and a second semiconductor layer are stacked.

[0060] Optionally, the light-emitting areas 310 and non-light-emitting areas 320 of at least two of the light-emitting elements 130 may be configured differently.

[0061] It should be noted that the different arrangement of the light-emitting element 130 in this embodiment refers to the fact that the light-emitting element 130 is measured by the positional relationship between the light-emitting area 310 and the non-light-emitting area 320. That is, the orientational relationship between the light-emitting area 310 and the non-light-emitting area 320 is different.

[0062] This embodiment can display light evenly, avoiding the localized concentration of crosstalk problems that are visible to the naked eye.

[0063] For example Figure 3 As shown, the arrangement of the light-emitting area 310 and the non-light-emitting area 320 has at least two different arrangement directions, and these two directions are not parallel. One of the directions is not parallel to the plane on which the display panel is located.

[0064] In other words, one of the light-emitting elements 130 is tilted relative to the other light-emitting element 130 in the direction from one light-emitting element 130 to the other light-emitting element 130.

[0065] For example, the light-emitting element 130 includes a first light-emitting element 131 and a second light-emitting element 132;

[0066] Optionally, the light-emitting area 310 and the non-light-emitting area 320 of the first light-emitting element 131 are arranged along direction A, and the light-emitting area 310 and the non-light-emitting area 320 of the second light-emitting element 132 are arranged along direction B. More specific embodiments will be described below, and will not be repeated here.

[0067] Or for example Figure 4 As shown, Figure 4 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 1Another local cross-sectional view in the AA direction.

[0068] Optionally, the spacing between at least two of the light-emitting elements 130 is greater than or less than the spacing between the light-emitting areas of the two light-emitting elements.

[0069] Optionally, the "spacing" mentioned above refers to the distance between the centers of the orthographic projections of the two structures onto the plane where the display panel is located. The "center" can be understood as the geometric center of the orthographic projection of the structure onto the plane where the display panel is located.

[0070] In other words, the different arrangement of the light-emitting element 130 in this embodiment refers to the different arrangement directions of the light-emitting area 310 and the non-light-emitting area 320 of the two light-emitting elements 130.

[0071] Optionally, the light-emitting areas 310 and non-light-emitting areas 320 of the two light-emitting elements are arranged in opposite directions. That is, there are at least two different arrangement directions for the light-emitting areas 310 and non-light-emitting areas 320, and these two directions are parallel but opposite to each other.

[0072] For example, the light-emitting element 130 includes a first light-emitting element 131 and a second light-emitting element 132 arranged sequentially along a direction X1, which is parallel to the first direction X. Optionally, the light-emitting area 310 and the non-light-emitting area 320 of the first light-emitting element 131 are arranged sequentially along the X1 direction, and the light-emitting area 310 and the non-light-emitting area 320 of the second light-emitting element 132 are arranged sequentially along the X2 direction. More specific embodiments will be described below, and will not be repeated here.

[0073] like Figure 5 As shown, Figure 5 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 1 Another local cross-sectional view in the AA direction.

[0074] Optionally, the display panel 100 further includes a color conversion layer 20, which is located on the side of the light-emitting element 130 away from the array substrate 120.

[0075] Optionally, the color conversion layer 20 includes quantum dots, also known as nanocrystals or nanoparticles, with a particle size typically between 1-10 nm. Nanoparticles, due to the quantum confinement of electrons and holes within a continuous band structure, become discrete energy level structures with molecular characteristics, and can emit fluorescence upon excitation. The emission spectrum of quantum dots can be controlled by changing their size. By altering the size and chemical composition of the quantum dots, their emission spectrum can cover the entire visible light region, exhibiting a broad excitation spectrum and a narrow emission spectrum, thus achieving high spectral coverage.

[0076] Of course, in some other alternative embodiments of this application, the color conversion unit includes fluorescent materials, such as organic phosphors, which will not be described in detail here.

[0077] Optionally, the light-emitting element 130 is a first-color light-emitting element. That is, the light-emitting elements 130 included in pixels sp of different colors emit the same color light and all emit light of the first color.

[0078] Optionally, the color conversion layer 20 corresponding to the pixel sp can convert the light of the first color into light of the color corresponding to the pixel sp.

[0079] Specifically, the color conversion layer 20 includes multiple units, each corresponding to a different pixel sp.

[0080] Optionally, the display panel 100 includes multiple pixels sp of different colors. The pixel sp array is arranged in the display area AA. Some pixel sp includes a pair of light-emitting elements 130 and color conversion layer 20 units arranged opposite each other. Different colored pixel sp includes color conversion layers 20 with different emitted light colors; after the incident light passes through the color conversion layer 20, it can be converted into light with a specific color, so that the pixel sp emits light of the corresponding color.

[0081] Optionally, in this embodiment of the invention, the color conversion layers 20 included in pixels sp of different colors emit different colors of light. For example, for a display panel using RGB three-color display technology, a color conversion layer with a red light emission color is selected for the position corresponding to a red pixel, a color conversion layer with a green light emission color is selected for the position corresponding to a green pixel, and a color conversion layer with a blue light emission color is selected for the position corresponding to a blue pixel.

[0082] Optionally, the pixel sp of the first color does not correspond to the color conversion layer 20.

[0083] For example, light-emitting elements emitting blue light are set at the positions of red, green, and blue pixels. The blue light emitted by the light-emitting elements is converted into red and green light respectively after passing through color conversion units of different colors; while no color conversion unit is set at the position of the blue pixel.

[0084] Of course, in some other optional embodiments of this application, the light-emitting element can be uniformly white, and the white light emitted by the light-emitting element is converted into red light, green light and blue light respectively after passing through color conversion units of different colors; here, this embodiment will not elaborate further.

[0085] This embodiment can further improve the display effect of the display panel.

[0086] Please continue to refer to this. Figure 5As shown, optionally, the display panel 100 may also include a counter-side substrate 400 disposed opposite to the array substrate, and a plurality of baffles 200.

[0087] The barrier 200 is located on the side of the opposite substrate 400 facing the array substrate 120, and is arranged corresponding to the spacing between the light-emitting elements 130.

[0088] Specifically, the barrier 200, the light-emitting element 130, and the color conversion layer 20 are located between the opposite substrate 400 and the array substrate 120.

[0089] The light-emitting element 130 is mounted on the side of the array substrate 120 facing the opposite substrate 400.

[0090] The barrier 200 is supported on the opposite substrate 400 facing the array substrate 120.

[0091] The color conversion layer 20 is carried on the opposite substrate 400 facing the array substrate 120.

[0092] Optionally, the opening 221 of the retaining wall 200 defines a pixel sp. For example, an opening 221 of the retaining wall 200 defines one pixel sp.

[0093] Optionally, the color conversion layer 20 is at least partially located in the opening 221 of the barrier 200, and one unit of the color conversion layer 20 corresponds to one opening 221 of the barrier 200.

[0094] Optionally, the display panel 100 may further include a color filter layer 500.

[0095] The color filter layer 500 includes a color resist 510, which is disposed corresponding to the light-emitting element 130.

[0096] Optionally, the color filter layer 500 also includes a black matrix BM, which corresponds to the spacing between pixels sp, and the opening of the black matrix BM corresponds to the setting of the color resist 510.

[0097] Optionally, the color resist 510 corresponds to the opening 221 of the barrier 200.

[0098] Understandably, multiple color resists 510 form multiple color resist units of different colors, with one color resist unit corresponding to one pixel sp, or one color resist unit corresponding to one opening 221.

[0099] Optionally, the color conversion layer 20 is located on the side of the color resist 510 close to the array substrate 120.

[0100] In this embodiment, the light emitted by the light-emitting element 130 can first pass through the color conversion layer 20. The light excited by the color conversion layer 20 will then pass through the color filter 510 with the corresponding color during its continued propagation. The color filter 510 can filter out some of the light that has not been completely excited by the color conversion layer 20, thereby ensuring the chromaticity of the light emitted from the pixel sp.

[0101] Please continue to refer to this. Figure 5 As shown, optionally, the light-emitting element 130 includes a first light-emitting element 131 and a second light-emitting element 132;

[0102] Optional, such as Figure 5 As shown by the midpoint-line arrow, the distance from the light-emitting area of ​​the first light-emitting element 131 to the second light-emitting element 132 is D1; ​​the distance from the non-light-emitting area 320 of the first light-emitting element 131 to the second light-emitting element 132 is D2; where D1>D2.

[0103] In other words, in the luminous and non-luminous areas corresponding to the first luminous element, the non-luminous area is located on the side of the luminous area closer to the second luminous element. The luminous area corresponding to the first luminous element is farther away from the second luminous element than its non-luminous area.

[0104] Optionally, the first light-emitting element 131 and the second light-emitting element 132 are light-emitting elements 130 in adjacent pixels sp; that is, the first light-emitting element 131 and the second light-emitting element 132 are arranged adjacent to each other.

[0105] The above design allows the light-emitting area of ​​the first light-emitting element to be kept away from the second light-emitting element, thereby avoiding the influence of the first light-emitting element on the second light-emitting element.

[0106] Furthermore, the first light-emitting element 131 and the second light-emitting element 132 have the same color.

[0107] Optionally, the color of the first light-emitting element 131 is different from the color of its corresponding pixel sp, and the color of the second light-emitting element 132 is the same as the color of its corresponding pixel sp.

[0108] Optionally, the pixel sp corresponding to the first light-emitting element 131 is provided with a color conversion layer 20; the pixel sp corresponding to the second light-emitting element 132 is not provided with a color conversion layer 20.

[0109] Optionally, the first light-emitting element 131 is disposed in a green pixel or a red pixel, and the second light-emitting element 132 corresponds to a blue pixel.

[0110] This embodiment avoids the impact of crosstalk of the same color light in adjacent light-emitting elements on color purity, thus reducing NTSC. Specifically, it is illustrated using a blue Micro-LED light-emitting element and a quantum dot layer as the color conversion layer. Since the Micro-LED in the quantum dot color filter module only provides blue light, blue light from the R and G pixels can easily crosstalk into adjacent blue pixels and be emitted from them, reducing the color purity of the display.

[0111] In this embodiment, since Micro-LEDs emit light only at one electrode position, the emitting electrode is moved away from the blue pixel, that is, the emitting area of ​​the non-blue pixel light-emitting element is moved away from the blue pixel. This reduces the light angle that illuminates the adjacent blue pixel, reduces the amount of light from the light-emitting elements corresponding to the R and G pixels entering the blue pixel, thereby reducing crosstalk and increasing color purity.

[0112] like Figure 6 As shown, Figure 6 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 1 Another local cross-sectional view in the AA direction.

[0113] The light-emitting element 130 includes a first light-emitting element 131 and a second light-emitting element 132;

[0114] The plane of the light-emitting area 310 of the first light-emitting element 131 is not parallel to the plane of the display panel 100, and the top surface is tilted toward the side away from the second light-emitting element.

[0115] In other words, along the direction from the first light-emitting element 131 to the second light-emitting element 132, the light-emitting area of ​​the first light-emitting element 131 is tilted toward the direction away from the array substrate 120.

[0116] With this design, the light-emitting area of ​​at least one of the two light-emitting elements can be tilted away from the other light-emitting element. For example, the top surface of the light-emitting area of ​​the first light-emitting element can be made to face away from the second light-emitting element, thus avoiding crosstalk between adjacent light-emitting elements.

[0117] Furthermore, the first light-emitting element 131 and the second light-emitting element 132 have the same color.

[0118] Optionally, the color of the first light-emitting element 131 is different from the color of its corresponding pixel sp, and the color of the second light-emitting element 132 is the same as the color of its corresponding pixel sp.

[0119] Optionally, the pixel sp corresponding to the first light-emitting element 131 is provided with a color conversion layer 20; the pixel sp corresponding to the second light-emitting element 132 is not provided with a color conversion layer 20.

[0120] Optionally, the first light-emitting element 131 is disposed in a green pixel or a red pixel, and the second light-emitting element 132 corresponds to a blue pixel.

[0121] This embodiment allows at least one of two adjacent light-emitting elements of the same color to be tilted away from the other, preventing crosstalk of the same color light between adjacent light-emitting elements from affecting color purity and reducing NTSC. Specifically, this is illustrated using a blue Micro-LED light-emitting element and a quantum dot layer as the color conversion layer. Since the Micro-LED in the quantum dot color filter module only provides blue light, blue light from the R and G pixels can easily crosstalk into adjacent blue pixels and be emitted from them, reducing the displayed color purity.

[0122] In this embodiment, by tilting the light-emitting area of ​​the light-emitting element in the pixel adjacent to the blue pixel toward the direction away from the blue pixel, the main light-emitting direction of the light-emitting element after the tilting of the light-emitting area is away from the blue pixel, thereby reducing the light-receiving angle of the adjacent blue pixel and reducing the light from the light-emitting elements corresponding to the R and G pixels entering the blue pixel, thereby reducing crosstalk and increasing color purity.

[0123] Of course, in other alternative embodiments of this application, for example Figure 2 As shown, optionally, the light-emitting element 130 includes a first light-emitting element 131 and a second light-emitting element 132;

[0124] The plane containing the first light-emitting element 131 is not parallel to the plane containing the display panel 100, and its top surface is tilted towards the side away from the second light-emitting element. It should be noted that in this embodiment, the tilt is not limited to the light-emitting area of ​​the light-emitting element, but rather the entire light-emitting element is tilted. That is, in the direction from which the first light-emitting element 131 points to the second light-emitting element 132, the top surface of the first light-emitting element 131 is tilted towards the direction away from the array substrate 120.

[0125] It is understood that the top surface of the light-emitting element or the top surface of the light-emitting area mentioned in this application refers to the surface of the light-emitting element or the light-emitting area facing away from the substrate.

[0126] With this design, at least one of the two light-emitting elements can be tilted so that its back faces the other light-emitting element, for example, so that the top surface of the first light-emitting element faces away from the second light-emitting element, thus avoiding crosstalk between adjacent light-emitting elements.

[0127] Furthermore, in the light-emitting area 310 and the non-light-emitting area 320 corresponding to the first light-emitting element 131, the non-light-emitting area 320 is located on the side of the light-emitting area 310 closer to the second light-emitting element.

[0128] With this design, since the top surface of the first light-emitting element 131 is tilted away from the second light-emitting element 132, the non-light-emitting area 320 in the first light-emitting element 131 will be closer to the second light-emitting element 132 and further away from the array substrate 120 than the light-emitting area 310 of the first light-emitting element 131. Therefore, the non-light-emitting area 320 can be used to better block the interference light emitted by the first light-emitting element towards the pixel where the second light-emitting element 132 is located in the possible light-emitting path of the first light-emitting element 131.

[0129] like Figure 7 As shown, Figure 7 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 1 Another local cross-sectional view in the AA direction.

[0130] The display panel 100 also includes a support portion 700 located between the light-emitting element 130 and the array substrate 120.

[0131] Optionally, the support portion 700 can support the light-emitting element 130 on the array substrate 120 and connect the light-emitting element 130 and the array substrate 120.

[0132] Optionally, the light-emitting element 130 includes a first light-emitting element 131 and a second light-emitting element 132;

[0133] The support portion 700 includes a first support portion 710 and a second support portion 720.

[0134] Optionally, a set of support portions 700 includes at least one first support portion 710 and at least one second support portion 720. At least one light-emitting element 130 corresponds to a set of first support portions 710 and second support portions 720. For example, a first light-emitting element 131 is connected to the array substrate 120 through a set of support portions 700; a second light-emitting element 132 is connected to the array substrate 120 through another set of support portions 700.

[0135] Optionally, in a set of support portions 700 corresponding to the first light-emitting element 131: the first support portion 710 is located on the side of the second support portion 720 close to the second light-emitting element 132, and the first support portion 710 is higher than the second support portion 720.

[0136] With the above design, the top surface of the first light-emitting element 131 can be tilted toward the side away from the second light-emitting element. That is, in the direction along which the first light-emitting element 131 points to the second light-emitting element 132, the top surface of the first light-emitting element 131 is tilted toward the direction away from the array substrate 120.

[0137] Optionally, the support section is opaque.

[0138] Since the top surface of the first light-emitting element is tilted in the direction away from the array substrate 120 due to the support, it can also prevent the bottom surface of the light-emitting area of ​​the first light-emitting element from emitting crosstalk light towards the pixel where the second light-emitting element is located.

[0139] Furthermore, the inventors of this application discovered that after the first light-emitting element is lit, the light emitted by the first light-emitting element can easily crosstalk to the corresponding pixel of the adjacent second light-emitting element through the gap between the bottom of the barrier and the array substrate. The first support portion is located on the side of the second support portion closer to the second light-emitting element, and the first support portion is higher than the second support portion, meaning the height of the first support portion is increased. Therefore, the light emitted by the first light-emitting element can be further prevented from affecting the second light-emitting element.

[0140] Optional, please continue to refer to Figure 7 As shown, in the light-emitting area 310 and non-light-emitting area 320 corresponding to the first light-emitting element 131, the non-light-emitting area 320 is located on the side of the light-emitting area 310 closer to the second light-emitting element.

[0141] Optionally, the first light-emitting element and the second light-emitting element have the same color.

[0142] Optionally, the color of the first light-emitting element is the same as the color of its corresponding pixel, while the color of the second light-emitting element is different from the color of its corresponding pixel.

[0143] Optionally, the pixels corresponding to the color of the first light-emitting element do not have a color conversion layer; the pixels corresponding to the color of the second light-emitting element have a color conversion layer. For example, the first light-emitting element corresponds to a green or red pixel, and the second light-emitting element corresponds to a blue pixel.

[0144] In this embodiment, since the top surface of the first light-emitting element 131 is tilted away from the second light-emitting element 132, the non-light-emitting area 320 in the first light-emitting element 131 will be closer to the second light-emitting element 132 and further away from the array substrate 120 than the light-emitting area 310 of the first light-emitting element 131. Therefore, the non-light-emitting area 320 can be used to better block the interference light emitted by the first light-emitting element 131 towards the pixel where the second light-emitting element 132 is located in the possible light-emitting path of the first light-emitting element 131.

[0145] Furthermore, the inventors of this application discovered that when adjacent pixels of a blue pixel are lit, the light emitted by the Micro-LED within that pixel can easily crosstalk into the blue pixel through the gap between the barrier and the array substrate. Therefore, optionally, the support portion is opaque. Since the elevation of the non-light-emitting area in the first light-emitting element is achieved by the support portion, it also prevents the bottom surface of the light-emitting area of ​​the first light-emitting element from emitting crosstalk light towards the pixel containing the second light-emitting element.

[0146] Optionally, the first support portion is 0 μm to 5 μm higher than the second support portion. That is, the first support portion 710 is 0 μm to 5 μm higher than the second support portion 720.

[0147] Unless otherwise specified, the height of the support portion mentioned in this application refers to the dimension of the support portion along the direction perpendicular to the plane of the display panel.

[0148] This embodiment satisfies the requirement for the support to tilt the light-emitting element, thus meeting the requirement for the light-emitting element to "reduce the light-receiving angle of adjacent blue pixels"; it also avoids excessive tilting of the light-emitting element, which would cause the light-emitting direction of the light-emitting area to deviate excessively; and it can also help to block the gap crosstalk between the bottom of the barrier wall and the array substrate.

[0149] Optionally, the support portion 700 corresponding to the second light-emitting element 132 has the same height as the second support portion 720 of the first light-emitting element 131.

[0150] Optionally, the support portion 700 corresponding to the second light-emitting element 132 also includes a set of support portions, that is, the second light-emitting element 132 corresponds to at least one first support portion 710 and at least one second support portion 720; wherein, the second support portion 700 corresponding to the first light-emitting element 131, the first support portion 710 corresponding to the second light-emitting element 132, and the second support portion 720 corresponding to the second light-emitting element 132 have the same height. The "height" can be understood as the dimension of each of the three portions in the direction perpendicular to the plane of the display panel.

[0151] Optionally, the height of the first support portion 710 corresponding to the second light-emitting element 132 and the second support portion 720 corresponding to the second light-emitting element 132 is less than that of the first support portion 710 corresponding to the first light-emitting element 131.

[0152] Optionally, the following three directions are consistent: the arrangement direction of the first light-emitting element 131 and the second light-emitting element 132, the arrangement direction of the light-emitting area 310 and the non-light-emitting area 320 of the first light-emitting element 131, and the arrangement direction of the first support portion 710 and the second support portion 720 corresponding to the first light-emitting element 131.

[0153] In this embodiment, the overall height of the second light-emitting element 132 can be smaller than that of the first light-emitting element 131; at least the overall height of the second light-emitting element 132 is smaller than the non-light-emitting area 320 of the first light-emitting element 131. The pixels corresponding to the second light-emitting element 132 can avoid light from the light-emitting area 310 of the first light-emitting element 131 through the raised non-light-emitting area 320 of the first light-emitting element 131. Furthermore, the pixels corresponding to the first light-emitting element can also help block light leakage from the second light-emitting element through the raised non-light-emitting area 320 of the first light-emitting element 131, further improving the display effect of the display panel.

[0154] Of course, in some other alternative embodiments of this application, the tilt of the light-emitting element can be achieved in other ways, such as... Figure 6 As shown, by adding raised structures to the surface of the array substrate—that is, by adding multiple raised structures to the side of the array substrate closest to the light-emitting element—the original structure of the array substrate and the light-emitting element can be simplified and costs reduced without changing them. Optionally, the raised structures can be provided corresponding to the side of the light-emitting element that needs to be elevated, with the elevated end of the light-emitting element placed on the raised structure. Alternatively, the raised structure can have an inclined top surface with the same tilt direction as the light-emitting element, and the entire light-emitting element can be placed on the raised structure.

[0155] like Figure 8 As shown, Figure 8 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 1 Another local cross-sectional view in the AA direction.

[0156] Optionally, the display panel 100 may also include a light-shielding portion 600 located between the light-emitting element 130 and the array substrate 130.

[0157] Optionally, the light-shielding part 600 can be made of light-shielding metal material or black material.

[0158] Optionally, the light-emitting element 130 includes a first light-emitting element 131 and a second light-emitting element 132;

[0159] The light-shielding part 600 is located on the side of the light-emitting area 310 of the first light-emitting element 131 that is close to the second light-emitting element 132.

[0160] Through the above design, the light emitted by the light-emitting area of ​​the first light-emitting element can be blocked by the light-shielding part, thereby preventing the light-emitting area of ​​the first light-emitting element from emitting crosstalk light towards the pixel where the second light-emitting element is located.

[0161] Optionally, in the luminous area 310 and non-luminous area 320 corresponding to the first light-emitting element 131, the non-luminous area 320 is located on the side of the luminous area 310 closer to the second light-emitting element. This is because the light transmittance of a material is related to its thickness (the dimension in the direction of light propagation). Through the above design of the first light-emitting element, a sufficient distance is maintained between the luminous area of ​​the first light-emitting element and the corresponding pixel of the second light-emitting element, providing sufficient space for the light-blocking portion 600 to achieve a sufficient light-blocking effect.

[0162] Optionally, the first light-emitting element and the second light-emitting element have the same color.

[0163] Optionally, the color of the first light-emitting element is the same as the color of its corresponding pixel, while the color of the second light-emitting element is different from the color of its corresponding pixel.

[0164] Optionally, the pixels corresponding to the color of the first light-emitting element do not have a color conversion layer; the pixels corresponding to the color of the second light-emitting element have a color conversion layer. For example, the first light-emitting element corresponds to a green or red pixel, and the second light-emitting element corresponds to a blue pixel.

[0165] In this embodiment, even if there is a gap between the bottom of the barrier and the array substrate, since the side of the light-emitting area of ​​the first light-emitting element 131 facing the pixel corresponding to the second light-emitting element has both the non-light-emitting area of ​​the first light-emitting element 131 and the barrier and light-shielding part, it can better block the interference light emitted by the first light-emitting element towards the pixel where the second light-emitting element 132 is located in the possible light-emitting path of the first light-emitting element 131.

[0166] In other alternative embodiments of this application, please refer to the accompanying drawings of embodiments with support portions or light-shielding portions.

[0167] Optionally, the support portion 700 or the light-shielding portion 600 may be a conductive portion that electrically connects the light-emitting element 130 to the array substrate 120. Optionally, the conductive portion may include a eutectic layer.

[0168] Specifically, the array substrate has connection electrodes that connect to the pixel circuit. These connection electrodes are typically metal electrodes, located on the outermost layer of the array substrate or exposed by an insulating layer on the array substrate, thereby making contact with the electrode layer of the light-emitting element transferred to the array substrate. Optionally, the metal electrodes on the array substrate can be melted to form a eutectic structure (also called a eutectic layer) with the electrode layer of the light-emitting element, achieving electrical connection between the light-emitting element and the array substrate (including the pixel circuit).

[0169] Of course, in some alternative embodiments of this application, the conductive portion includes the connection electrode on the array substrate, the electrode layer of the light-emitting element, and the eutectic layer formed by the two.

[0170] Through the above design, on the one hand, it can avoid adding other structures to the conductive part that connects the light-emitting element and the array substrate, thus avoiding pressure on the conductive part and occupying space in other areas. It can also avoid the additional support or light-shielding part from hindering the connection between the light-emitting element and the array substrate. For example, due to errors, the height of the support or light-shielding part may deviate, causing the gap between the light-emitting element and the array substrate to be too large after being separated by the support or light-shielding part, making it impossible to make contact through the conductive part. On the other hand, it can simplify the manufacturing process of the display panel and reduce the cost of the display panel. Furthermore, it can reduce the number of film layers in the display panel and avoid excessively increasing the thickness of the display panel.

[0171] Optionally, the support and the light-shielding parts can be reusable structures.

[0172] In other words, in some optional embodiments of this application, the support portion is the light-shielding portion.

[0173] Furthermore, in some alternative embodiments of this application, the support portion is the light-shielding portion, and also the conductive portion that realizes the electrical connection between the light-emitting element and the array substrate.

[0174] like Figure 9 As shown, Figure 9 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 1 Another local cross-sectional view in the AA direction.

[0175] Optionally, the light-shielding portion 600 is a conductive portion that electrically connects the light-emitting element 130 to the array substrate 120. Optionally, the conductive portion 700 includes a eutectic layer.

[0176] like Figure 10 As shown, Figure 10 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 1 Another local cross-sectional view in the AA direction.

[0177] Optionally, the display panel 100 may also include a light-shielding portion 600 located between the light-emitting element 130 and the array substrate 130.

[0178] Optionally, the light-shielding part 600 can be made of light-shielding metal material or black material.

[0179] Optionally, the light-shielding part 600 includes a first light-shielding part 610 and a second light-shielding part 620.

[0180] Optionally, a set of light-shielding portions 600 includes at least one first light-shielding portion 610 and at least one second light-shielding portion 620. At least one light-emitting element 130 (taking the first light-emitting element 131 as an example) corresponds to a set of first light-shielding portions 610 and second light-shielding portions 620.

[0181] Optionally, the first light-shielding portion 610 and the second light-shielding portion 620 in a set of light-shielding portions 600 are arranged along a first direction X. For example, the first light-shielding portion 610 and the second light-shielding portion 620 in a set of light-shielding portions 600 are located at opposite ends of the light-emitting element in the first direction X. The first direction X is consistent with the arrangement direction of the light-emitting area 310 and the non-light-emitting area 320 of the first light-emitting element 131.

[0182] Optionally, in the light-shielding portion 600 corresponding to the first light-emitting element 131, the first light-shielding portion 610 is located on the side of the second light-shielding portion 620 close to the second light-emitting element 132, and the size of the first light-shielding portion 610 is larger than the size of the second light-shielding portion 620.

[0183] In this embodiment, two light-shielding parts are simultaneously provided for the first light-emitting element, and the arrangement of the light-emitting area and the non-light-emitting area of ​​the first light-emitting element is combined with the design of two types of light-shielding parts of different sizes. This not only blocks the interference light emitted by the first light-emitting element toward the pixel where the second light-emitting element is located, but also avoids excessive differences in crosstalk between the first light-emitting element and the pixels on both sides in the first direction when the light-emitting area and the non-light-emitting area of ​​the first light-emitting element are set at different distances relative to adjacent pixels in the first direction, in order to meet the above requirements.

[0184] It should be noted that the size of the light-shielding part mentioned in this embodiment may also include the length of the light-shielding part in the first direction X in some cases, which can increase the thickness of the light-shielding part in the direction of light propagation and improve the light-shielding ability.

[0185] Of course, in some other alternative embodiments of this application, such as Figure 11 and Figure 12 As shown, Figure 11 A partial bottom view (i.e., viewed from the array substrate towards the opposite substrate) of a display panel provided in an embodiment of the present invention. Figure 12 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 11 A partial cross-sectional view along the AA direction, the cross-section being perpendicular to the plane containing the display panel. This is for emphasis and ease of understanding. Figure 11 Some structural details are omitted, such as the array substrate, which is not shown; and the similarities between this embodiment and the above embodiments will not be repeated. The dimensions of the light-shielding portion 600 mentioned above include the length of the light-shielding portion in the second direction Y, that is, in the light-shielding portion 600 corresponding to the first light-emitting element 131, the length of the first light-shielding portion 610 in the second direction Y is greater than the length of the second light-shielding portion 620 in the second direction Y.

[0186] The second direction Y intersects (optionally, perpendicularly) the first direction X and is parallel to the plane of the display panel. Thus, in this embodiment, the second light-shielding part can block the light emitted by the first light-emitting element from the corresponding pixel of the second light-emitting element in an oblique direction (referring to the emitted light from the first light-emitting element that is parallel to the plane of the display panel and towards the second light-emitting element, but not parallel to the first direction).

[0187] In some cases, the size of the light-shielding portion mentioned in this embodiment may also include the thickness of the light-shielding portion in the direction perpendicular to the plane of the display panel. This is because the inventors of this application have further discovered that after a pixel is lit, the light emitted by its light-emitting element can easily crosstalk to adjacent pixels through the gap between the barrier and the array substrate. Therefore, increasing the thickness of the light-shielding portion in the direction perpendicular to the plane of the display panel can further prevent the light-emitting area of ​​the first light-emitting element from emitting crosstalk light towards the pixel containing the second light-emitting element.

[0188] Of course, in some other optional embodiments of this application, the area of ​​the first light-shielding part 610 (referring to the projected area on the plane where the display panel is located) is larger than the area of ​​the second light-shielding part 620. Alternatively, the volume of the first light-shielding part 610 is larger than the volume of the second light-shielding part 620.

[0189] Optionally, the first light-shielding part 610 may overlap with the projection of the light-emitting area 310 in a direction perpendicular to the plane of the display panel, and the second light-shielding part 620 may overlap with the projection of the non-light-emitting area 320 in a direction perpendicular to the plane of the display panel.

[0190] Optionally, the first light-shielding portion 610 and the second light-shielding portion 620 respectively reuse the conductive portion that connects the light-emitting element and the array substrate, and the conductive portion includes a eutectic layer. For example, the first light-shielding portion 610 and the second light-shielding portion 620 respectively correspond to the first electrode and the second electrode of the electrode layer 103 of the light-emitting element.

[0191] like Figure 13 As shown, Figure 13 This is a partial bottom view of a display panel provided in an embodiment of the present invention.

[0192] Optionally, the display panel 100 may also include a light-shielding portion 600 located between the light-emitting element 130 and the array substrate 130.

[0193] Optionally, the light-shielding part 600 can be made of light-shielding metal material or black material.

[0194] Optionally, the light-emitting element 130 includes a first light-emitting element 131 and a second light-emitting element 132;

[0195] The light-shielding part 600 is located on the side of the light-emitting area 310 of the first light-emitting element 131 that is close to the second light-emitting element 132.

[0196] Optionally, the first light-emitting element 131 and the second light-emitting element 132 are arranged along the first direction X. That is, along the first direction X, the pixel sp corresponding to the first light-emitting element 131 and the pixel sp corresponding to the second light-emitting element 132 are arranged adjacent to each other.

[0197] Optionally, the display panel 100 further includes a barrier 200; the barrier 200 is located between the light-emitting elements 130; wherein, the specific structure of the barrier in this embodiment can be referred to other embodiments of this application involving barrier, and will not be repeated here.

[0198] Optionally, the barrier 200 includes a first barrier 201 located between the first light-emitting element 131 and the second light-emitting element 132, the first barrier 201 extending along a second direction Y. The second direction Y intersects (optionally, perpendicularly to) the first direction X and is parallel to the plane of the display panel 100.

[0199] Optionally, along the first direction X: the distance from the light-emitting area 310 of the first light-emitting element 131 to the light-shielding part 600 is L1, and the distance from the light-emitting area 310 of the first light-emitting element 131 to the first barrier wall 201 is L2; ​​it should be noted that the "distance" here refers to the distance component in the first direction X, that is, the distance between the two refers to the coordinate difference between their positions on the coordinate axis parallel to the first direction X.

[0200] Along the second direction Y: the distance from the light-emitting area 310 of the first light-emitting element 131 to the light-shielding part 600 is H1, and the distance from the light-emitting area 310 of the first light-emitting element 131 to the first barrier wall 201 is H2; it should be noted that the "distance" here refers to the distance component in the second direction Y, that is, the distance between the two refers to the coordinate difference between their positions on the coordinate axis parallel to the second direction Y.

[0201] Optionally, H1>(L1*H2) / L2.

[0202] Optionally, the light-shielding part 600 described above can be the first light-shielding part 610 in other embodiments.

[0203] Optionally, the length of the light-shielding portion 600 in the second direction Y is greater than or equal to 2*H1.

[0204] It should be noted that the measurement positions of the above four distances (L1, L2, H1, H2) at the light-emitting area are the ends of the light-emitting area 310 of the first light-emitting element 131 that are furthest from the second light-emitting element 132. For example, the distance from the light-emitting area 310 of the first light-emitting element 131 to the light-shielding part 600 is the distance from the end of the light-emitting area 310 of the first light-emitting element 131 that is furthest from the second light-emitting element 132 to the light-shielding part 600.

[0205] In this embodiment, the size of the light-shielding part in the second direction is set so that the line connecting the edge of the light-emitting area of ​​the first light-emitting element and the edge of the light-shielding part passes exactly through the edge point of the pixel corresponding to the second light-emitting element or the area outside the pixel corresponding to the second light-emitting element, without passing through the pixel corresponding to the second light-emitting element (which can also be understood as the opening area of ​​the barrier wall corresponding to the pixel), thereby further preventing light leakage into the second light-emitting element and improving the display effect.

[0206] like Figure 14 and Figure 15 As shown, Figure 14 This is a partial top view of a display panel provided in an embodiment of the present invention. Figure 15 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 14 A partial cross-sectional view along the AA direction is shown, the cross-section being perpendicular to the plane where the display panel is located. The similarities between this embodiment and the above embodiments will not be repeated.

[0207] Optionally, the light-emitting element 130 further includes a third light-emitting element 133. The second light-emitting element 132 is located between the first light-emitting element 131 and the third light-emitting element 133.

[0208] Optionally, the display panel includes an array of pixels arranged in a cyclic pattern along a first direction X, with pixels of three different colors arranged sequentially. The light-emitting elements corresponding to the three different colored pixels are a first light-emitting element 131, a second light-emitting element 132, and a third light-emitting element 133, respectively. Therefore, the first light-emitting element 131, the second light-emitting element 132, and the third light-emitting element 133 are arranged sequentially along the first direction X.

[0209] Optionally, the distance from the light-emitting area of ​​the second light-emitting element to the third light-emitting element is less than the distance from the light-emitting area of ​​the second light-emitting element to the first light-emitting element;

[0210] That is, in the first direction X, the second light-emitting element 132 is disposed between the first light-emitting element 131 and the third light-emitting element 133, and the light-emitting area 310 and the non-light-emitting area 320 of the second light-emitting element 132 are disposed along the first direction X, and the light-emitting area 310 of the second light-emitting element 132 is located towards the third light-emitting element 133 adjacent to the second light-emitting element 132 in the first direction X; then the non-light-emitting area 320 of the second light-emitting element 132 is close to the first light-emitting element 131.

[0211] Optionally, the wavelength of the color light of the pixel sp corresponding to the first light-emitting element 131 is between the wavelength of the color light of the pixel sp corresponding to the second light-emitting element 132 and the wavelength of the color light of the pixel sp corresponding to the third light-emitting element 133.

[0212] This embodiment further prevents crosstalk. For example, consider a scenario where the first light-emitting element corresponds to a green pixel, the second light-emitting element corresponds to a blue pixel, and the third light-emitting element corresponds to a red pixel. This is because it's better for the light-emitting area of ​​the blue pixel's light-emitting element to be closer to the red pixel, as blue light is less likely to pass through the red color filter.

[0213] like Figure 16 As shown, Figure 16 The display panel provided in the embodiment of the present invention has the following characteristics: Figure 14 Another partial cross-sectional view along the AA direction, wherein the cross-section is perpendicular to the plane where the display panel is located. The similarities between this embodiment and the above embodiments will not be repeated.

[0214] Optionally, the arrangement of the second light-emitting element relative to the first light-emitting element can refer to the arrangement of the first light-emitting element relative to the second light-emitting element in the above embodiments. For example, the plane where the light-emitting area 310 of the second light-emitting element 132 is located is not parallel to the plane where the display panel 100 is located, and the top surface is tilted towards the side away from the first light-emitting element.

[0215] In other words, along the direction from the second light-emitting element 132 to the first light-emitting element 131, the light-emitting area of ​​the second light-emitting element 132 is tilted toward the direction away from the array substrate 120.

[0216] Optionally, the first light-emitting element 131 is disposed in the green pixel, and the second light-emitting element 132 is disposed in the blue pixel.

[0217] Optionally, in a set of support portions 700 corresponding to the second light-emitting element 132: the first support portion 710 is located on the side of the second support portion 720 close to the first light-emitting element 131, and the first support portion 710 is higher than the second support portion 720.

[0218] Of course, in some other optional embodiments of this application, the second light-emitting element or the light-emitting area of ​​the second light-emitting element may be set away from the pixel corresponding to the first light-emitting element; or the third light-emitting element or the light-emitting area of ​​the second light-emitting element may be set towards the pixel corresponding to the third light-emitting element.

[0219] In other words, the arrangement of the second light-emitting element relative to the first light-emitting element can refer to the arrangement of the first light-emitting element relative to the second light-emitting element in the above embodiments. That is, the light-emitting areas and non-light-emitting areas of the first and second light-emitting elements are arranged symmetrically.

[0220] The present invention also provides a display device, including the display panel provided by the present invention. For example... Figure 17 As shown, Figure 17 This is a schematic diagram of a display device provided in an embodiment of the present invention. The display device 1000 includes the display panel 100 provided in any of the above embodiments of the present invention.
