The directional terms mentioned in the present application, such as [up], [down], [front], [back], [left], [right], [inside], [outside], [side], etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present application, rather than to limit the present application. In the figures, units with similar structures are represented by the same reference numerals. In the accompanying drawings, the thickness of some layers and regions is exaggerated for clear understanding and ease of description. That is, the size and thickness of each component shown in the drawings are arbitrarily shown, but the present application is not limited to this.

[0034] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of a top view of the structure of a display panel provided in an embodiment of the present application is shown in FIG. Figure 2 A schematic cross-sectional structure diagram of a display panel provided in an embodiment of the present application, Figure 3 Schematic diagram of the structure of a display panel provided in an embodiment of the present application. The display panel 100 includes a substrate 10 and a plurality of pixels (such as Figure 1 Each of the pixels includes at least three light-emitting units of different colors arranged at intervals (e.g., Figure 1 The light-emitting units R, G, and B are shown in the figure). Among them, in any two adjacent pixels, a light-emitting unit of one pixel has the same color as an adjacent light-emitting unit of another pixel.

[0035] Specifically, the display panel 100 further includes first electrodes 30 and a pixel definition layer 40 arranged in an array on the substrate 10. The pixel definition layer 40 covers the substrate 10 and the first electrodes 30, and has a pixel opening 401 formed at a position corresponding to the first electrode 30, wherein the pixel opening 401 exposes the corresponding first electrode 30. Each of the light-emitting units is disposed in one of the pixel openings 401.

[0036] Specifically, the base plate 10 includes a substrate 11 and a driving circuit layer 12 disposed on the substrate 11. Optionally, a buffer layer 13 may be disposed between the substrate 11 and the driving circuit layer 12, and the material of the buffer layer 13 may include inorganic materials such as silicon oxide (SiOx), silicon nitride (SiNx), and silicon oxynitride (SiON). The buffer layer 13 may further prevent undesirable impurities or contaminants (such as moisture, oxygen, etc.) from diffusing from the substrate 11 to devices that may be damaged by these impurities or contaminants, and may also provide a flat top surface.

[0037] Optionally, the substrate 11 can be a rigid substrate or a flexible substrate; when the substrate 11 is a rigid substrate, it can include a rigid substrate such as a glass substrate 10; when the substrate 11 is a flexible substrate, it can include a flexible substrate such as a polyimide (PI) film, an ultra-thin glass film, etc. A flexible display panel can be manufactured using a flexible substrate as the substrate 11 to achieve special properties of the display panel 100 such as bending and curling.

[0038] The driving circuit layer 12 includes an active layer 121, a gate insulating layer 122, a gate 123, an interlayer insulating layer 124, a source-drain electrode layer 125, a passivation layer 126, and a planarization layer 127, which are sequentially stacked on the buffer layer 13. The active layer 121 includes a channel region 1211 and a source region 1212 and a drain region 1213 located on both sides of the channel region 1211. The gate insulating layer 122 covers the active layer 121 and is arranged corresponding to the channel region 1211. The gate 123 is arranged on the gate insulating layer 122, and the gate 123 is arranged corresponding to the channel region 1211.

[0039] Optionally, the substrate 10 further includes a light shielding layer 14, the light shielding layer 14 is disposed on the substrate 11, and the buffer layer 13 covers the light shielding layer 14 and the substrate 11. The light shielding layer 14 is disposed corresponding to the active layer 121, so that the orthographic projection of the active layer 121 on the substrate 11 falls within the orthographic projection range of the light shielding layer 14 on the substrate 11, that is, the light shielding layer 14 can completely shield the active layer 121 to prevent light from irradiating the active layer 121.

[0040] The interlayer insulating layer 124 covers the gate 123 and the buffer layer 13, and the source-drain layer 125 is arranged on the interlayer insulating layer 124. The source-drain layer 125 is patterned to form a source 1251, a drain 1252, etc. The source 1251 is connected to the source region 1212 through a via hole in the interlayer insulating layer 124, and the drain 1252 is connected to the drain region 1213 through another via hole in the interlayer insulating layer 124.

[0041] The passivation layer 126 covers the source / drain electrode layer 125 and the interlayer insulating layer 124, and the planarization layer 127 covers the passivation layer 126. The planarization layer 127 can provide a flat film surface for the substrate 10.

[0042] It should be noted that the structure of the driving circuit layer 12 of the present application is not limited to that illustrated in the present embodiment. The driving circuit layer 12 of the present application may also include more or fewer film layers, and the positional relationship of each film layer is also not limited to that illustrated in the present embodiment. For example, the gate 123 may also be located below the active layer 121 to form a bottom gate structure.

[0043] The first electrodes 30 are arranged in an array on the planarization layer 127 , and each of the first electrodes 30 is connected to the source 1251 or the drain 1252 through a via hole in the planarization layer 127 and the passivation layer 126 . The present application takes the connection between the first electrode 30 and the drain 1252 as an example.

[0044] Optionally, the first electrode 30 may be a transparent electrode or a reflective electrode. If the first electrode 30 is a transparent electrode, the first electrode 30 may be formed of, for example, indium tin oxide (ITO), indium zinc oxide (IZO), ZnO, or In2O3. If the first electrode 30 is a reflective electrode, the first electrode 30 may include, for example, a reflective layer formed of Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, or a combination thereof, and a layer formed of ITO, IZO, ZnO, or In2O3. However, the first electrode 30 is not limited thereto, and the first electrode 30 may be formed of various materials and may also be formed as a single layer or multilayer structure.

[0045] The pixel definition layer 40 covers the first electrode 30 and the planarization layer 127, and the pixel definition layer 40 is patterned to form a pixel opening 401. Each pixel opening 401 corresponds to one first electrode 30, and exposes a portion of the first electrode 30 to define a setting area of ​​the light-emitting unit. The light-emitting unit is set in the pixel opening 401 and covers the first electrode 30 in the pixel opening 401.

[0046] The light-emitting units of different colors are formed by printing light-emitting materials of different colors in the pixel opening 401. Specifically, the light-emitting materials of different colors are dissolved in different organic solutions to form inks of different colors, and then the inks of different colors are printed in different pixel openings 401 by inkjet printing or other processes to form the light-emitting units of different colors. The light-emitting materials of different colors emit light of different colors, for example, the red light-emitting material emits red light, the green light-emitting material emits green light, and the blue light-emitting material emits blue light, so that the light-emitting units of different colors emit light of different colors.

[0047] Specifically, the three light-emitting units of different colors are respectively a first color light-emitting unit B, a second color light-emitting unit R, and a third color light-emitting unit G, wherein the first color light-emitting unit B is a blue light-emitting unit, which emits blue light; the second color light-emitting unit R is a red light-emitting unit, which emits red light; and the third color light-emitting unit G is a green light-emitting unit, which emits green light. The surface shapes of the first color light-emitting unit B, the second color light-emitting unit R, and the third color light-emitting unit G are all triangles, but the present application is not limited thereto, and the surface shapes of the light-emitting units of the present application may also be other regular or irregular shapes.

[0048] Since each of the pixels includes at least three light-emitting units of different colors, that is, each of the pixels includes a first color light-emitting unit B, a second color light-emitting unit R and a third color light-emitting unit G, each of the pixels can display various colors, thereby enabling the display panel 100 to achieve color display.

[0049] It can be understood that in order to make the light-emitting unit emit light, the display panel 100 further includes a second electrode 60 disposed on the light-emitting unit and the pixel definition layer 40. The light-emitting unit emits light under the joint action of the first electrode 30 and the second electrode 60, and light-emitting units of different colors emit light of different colors, thereby realizing full-color display of the display panel 100. The first electrode 30 of the embodiment of the present application is an anode, and the second electrode 60 is a cathode. Of course, the present application is not limited thereto. The first electrode 30 of the present application may also be a cathode, and correspondingly, the second electrode 60 is an anode.

[0050] Optionally, in order to improve the transmittance of light, the second electrode 60 is formed of a transparent conductive material, for example, the second electrode 60 can be formed of a transparent conductive oxide (TCO) such as ITO, IZO, ZnO or In2O3.

[0051] Alternatively, the display panel 100 may further include a hole injection layer (HIL) and a hole transport layer (HTL) disposed between the light emitting unit and the first electrode 30; and an electron injection layer (EIL) and an electron transport layer (ETL) disposed between the light emitting unit and the second electrode 60. The hole injection layer receives holes transmitted by the first electrode 30, and the holes are transmitted to the light emitting unit via the hole transport layer; the electron injection layer receives electrons transmitted by the second electrode 60, and the electrons are transmitted to the light emitting unit via the electron transport layer; the holes and the electrons are combined at the light emitting unit to generate excitons, and the excitons transition from an excited state to a ground state to release energy and emit light.

[0052] Furthermore, in order to protect the light-emitting unit and prevent the light-emitting unit from failing due to water and oxygen intrusion, the display panel 100 further includes an encapsulation layer 70 disposed on the second electrode 60. Optionally, the encapsulation layer 70 may be a thin film encapsulation, for example, the encapsulation layer 70 may be a laminated structure formed by sequentially stacking three thin films of a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer, or a laminated structure of more layers.

[0053] In addition, since the colors of the two adjacent light-emitting units between each two adjacent pixels are the same, color mixing between adjacent pixels can be avoided, thereby improving display quality. The following will describe in detail how to make the colors of the adjacent light-emitting units between adjacent pixels the same:

[0054] Optionally, the display panel 100 includes a first pixel unit group 1 and a second pixel unit group 2 arranged in sequence along a first direction X, so that the first pixel unit group 1 and the second pixel unit group 2 are alternately arranged along the first direction X, wherein adjacent first pixel unit groups 1 and second pixel unit groups 2 are axially symmetrical. The first pixel unit group 1 and the second pixel unit group 2 each include two pixels. In the first pixel unit group 1 and the second pixel unit group 2, the two pixels are centrally symmetrical.

[0055] Optionally, the shape of the three light-emitting units of different colors of each pixel is a triangle, each of the light-emitting units includes two short sides and one long side, the length of the long side is greater than the length of the short side, and in each pixel, the vertices formed by the two short sides of each light-emitting unit are close to each other, and the extension lines of the long sides of each light-emitting unit form an isosceles triangle, that is, the shape of each pixel is an isosceles triangle, so that the first pixel unit group 1 and the second pixel unit group 2 formed by two pixels that are symmetrical to each other are both rhombuses.

[0056] Specifically, the first pixel unit group 1 includes a first pixel 20-1 and a second pixel 20-2, the first pixel 20-1 and the second pixel 20-2 are mutually symmetrical, and the shapes of the first pixel 20-1 and the second pixel 20-2 are both isosceles triangles. The second pixel unit group 2 includes a third pixel 20-3 and a fourth pixel 20-4, the third pixel 20-3 and the fourth pixel 20-4 are mutually symmetrical, and the shapes of the third pixel 20-3 and the fourth pixel 20-4 are both isosceles triangles. And because the adjacent first pixel unit group 1 and the second pixel unit group 2 are axially symmetrical, for the adjacent first pixel unit group 1 and the second pixel unit group 2, the first pixel 20-1 in the first pixel unit group 1 is axially symmetrical with the third pixel 20-3 in the second pixel unit group 2, and the second pixel 20-2 in the first pixel unit group 1 is axially symmetrical with the fourth pixel 20-4 in the second pixel unit group 2.

[0057] Further, in the second direction Y, the first pixel unit group 1 and the second pixel unit group 2 are both arranged in an array. Specifically, along the second direction Y, the first pixel unit group 1 and the second pixel unit group 2 are not adjacent. That is, in the second direction Y, the first pixel unit group 1 is arranged in a row alone, and the second pixel unit group 2 is also arranged in a row alone, and the first pixel unit group 1 and the second pixel unit group 2 are located in different rows. It should be noted that the first direction X of the present application can be a vertical direction, the second direction Y is a horizontal direction, and the first direction X is perpendicular to the second direction Y. Of course, the present application is not limited to this. The first direction X of the present application can also be a horizontal direction, and the second direction Y is a vertical direction, and the first direction X and the second direction Y can also be other angles.

[0058] Since the first pixel unit group 1 and the second pixel unit group 2 are arranged in an array in the second direction Y, and the two pixels in the first pixel unit group 1 and the two pixels in the second pixel unit group 2 are centrally symmetrical to each other, any two adjacent pixels along the second direction Y are centrally symmetrical to each other. At the same time, since the adjacent first pixel unit group 1 and the second pixel unit group 2 are axially symmetrical in the first direction X, the colors of the adjacent light-emitting units between any two adjacent pixels are the same. In this way, when the light-emitting units are printed using an inkjet printing process, since the colors of the adjacent light-emitting units between the two adjacent pixels are the same, even if the inkjet printing device has a limited nozzle precision and there is an error, which may cause the printing direction to change and thus inject the ink into the adjacent light-emitting units, it will not cause color mixing between pixels.

[0059] However, it is understandable that since the colors of adjacent light-emitting units in the same pixel are different, there is still a risk of color mixing in the pixel. In order to avoid color mixing between adjacent light-emitting units in the same pixel, a blocking layer 50 can be provided between adjacent light-emitting units in the same pixel to prevent ink from entering the adjacent light-emitting unit pits.

[0060] Specifically, the barrier layer 50 is arranged on the side of the pixel definition layer 40 away from the substrate 10, and is located between two adjacent light-emitting units of different colors. The material of the barrier layer 50 is a hydrophobic material. For example, the hydrophobic material can be formed by processing an organic photoresist material to aggregate fluoride ions on its surface. By arranging the barrier layer 50 between the two adjacent light-emitting units of different colors, the height of the barrier layer between the light-emitting units is increased, so that even if the print head deviation occurs, the barrier layer 50 can still block the deviated ink droplets and make them eventually flow into the target light-emitting unit pit. At the same time, the barrier layer 50 is made of hydrophobic material. When there are more ink droplets injected into the light-emitting unit pit, the surface tension caused by the hydrophobicity of the barrier layer 50 can ensure that the ink droplets are still in the light-emitting unit pit to avoid overflow.

[0061] In one embodiment, please refer to Figures 1 to 4 , Figure 4 Another schematic diagram of the top view structure of the display panel provided in the embodiment of the present application. Different from the above-mentioned embodiment, on the display panel 101 of the present embodiment, in the second direction Y, the first pixel unit group 1 and the second pixel unit group 2 are arranged alternately. At the same time, in the first direction X, the first pixel unit group 1 and the second pixel unit group 2 are also arranged alternately, so that each of the first pixel unit groups 1 is adjacent to four of the second pixel unit groups 2, and correspondingly, each of the second pixel unit groups 2 is also adjacent to four of the first pixel unit groups 1. Moreover, in the first direction X, the adjacent first pixel unit groups 1 and the second pixel unit groups 2 are axially symmetrical, and in the second direction Y, the adjacent first pixel unit groups 1 and the second pixel unit groups 2 are also axially symmetrical. At this time, the colors of the two adjacent light-emitting units between the two adjacent pixels can also be the same.

[0062] Specifically, in the first pixel unit group 1 and the second pixel unit group 2, the shape of the three light-emitting units of each pixel of different colors is a triangle, each light-emitting unit includes two short sides and one long side, the side length of the long side is greater than the side length of the short side, and in each pixel, the vertices formed by the two short sides of each light-emitting unit are close to each other, and the extension lines of the long sides of each light-emitting unit form a right triangle, that is, the shape of each pixel is a right triangle. In this way, the shapes of the first pixel unit group 1 and the second pixel unit group 2 formed by two mutually symmetrical pixels are both square, such as a rectangle or a square.

[0063] In addition, different from the above embodiment, in the same pixel, the area of ​​the first color light emitting unit B is larger than the area of ​​the second color light emitting unit R, and larger than the area of ​​the third color light emitting unit G. The first color light emitting unit B is a blue light emitting unit, and the luminous efficiency and life of the blue light emitting material are poor compared to the luminous efficiency and life of other color light emitting materials. Therefore, in each pixel, a blue light emitting unit with a larger area is provided to improve the service life of the display panel 101. For other descriptions, please refer to the above embodiment, which will not be repeated here.

[0064] In one embodiment, please refer to Figures 1 to 5 , Figure 5 Another schematic diagram of a top view structure of a display panel provided in an embodiment of the present application. Different from the above embodiment, in the display panel 102, in the first direction X, the adjacent first pixel unit group 1 and the second pixel unit group 2 are centrally symmetrical. In the second direction Y, multiple first pixel unit groups 1 are arranged in an array; in the second direction Y, multiple second pixel unit groups 2 are also arranged in an array.

[0065] Specifically, each of the first pixel unit groups 1 includes a first pixel 20-1 and a second pixel 20-2, and the first pixel 20-1 and the second pixel 20-2 are mutually symmetric. Each of the second pixel unit groups 2 includes a third pixel 20-3 and a fourth pixel 20-4, and the third pixel 20-3 and the fourth pixel 20-3 are mutually symmetric. At the same time, in the first direction X, any adjacent first pixel unit group 1 and the second pixel unit group 2 are also mutually symmetric, and in the second direction Y, any adjacent first pixel unit group 1 and the second pixel unit group 2 are also mutually symmetric. In this way, the structures of the first pixel unit group 1 and the second pixel unit group 2 are exactly the same, that is, the arrangement forms of the light-emitting units in the first pixel unit group 1 and the second pixel unit group 2 are exactly the same, so that between the two adjacent pixels, the colors of the adjacent light-emitting units are the same, and the process can be simplified. For other descriptions, please refer to the above embodiments, which will not be repeated here.

[0066] Based on the same inventive concept, an embodiment of the present application further provides an electronic device, which includes the display panel 100 of one of the above embodiments. The electronic device can be an electronic display product such as a mobile phone, a television, a tablet, a wearable display device, etc.

[0067] According to the above embodiments, it can be seen that:

[0068] The present application provides a display panel and an electronic device, the display panel comprising a substrate and a plurality of first pixel unit groups and a plurality of second pixel unit groups alternately arranged on the substrate along a first direction, each of the first pixel unit groups and each of the second pixel unit groups comprising two pixels that are centrally symmetrical to each other, each of the pixels comprising at least three light-emitting units of different colors arranged at intervals, and between any two adjacent pixels, a light-emitting unit of one pixel has the same color as an adjacent light-emitting unit of another pixel. The present application solves the problem of color mixing between pixels existing in existing OLED devices by making the adjacent light-emitting units between two adjacent pixels have the same color, so that when the light-emitting units are printed using an inkjet printing process, color mixing between pixels can be avoided.
