[0064] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0065] In related technologies, with the development of semiconductor lighting technology, various light-emitting device structures have been continuously proposed, and stacked OLED devices are one of them. Stacked OLED devices are devices that combine two or more OLED devices in series via a charge generation layer (CGL). Compared to single-layer OLED devices, stacked OLED devices can improve current efficiency, extend device life, and meet the required brightness requirements for lighting. The display panel includes film layers shared by multiple OLED devices, and the shared film layers may include at least the charge generation layer.

[0066] However, since stacked OLED devices have more shared film layers than single-layer OLED devices, the design of stacked OLED devices will aggravate the lateral crosstalk between sub-pixels in the display panel, resulting in poor display effects.

[0067] FIG1 is a schematic diagram of the structure of a display panel provided in an embodiment of the present application. FIG2 is a cross-sectional view of FIG1 along the AA direction. In conjunction with FIG1 and FIG2 , the display panel 10 includes: a base substrate 101, an isolation layer 102, and a plurality of pixel units 103. The base substrate 101 has a display area, the isolation layer 102 is located on one side of the base substrate 101, and the plurality of pixel units 103 are located on a side of the isolation layer 102 away from the base substrate 101 and in the display area.

[0068] 3 , each pixel unit 103 includes at least two light-emitting elements arranged in a stacked manner. A charge generation layer CGL is provided between at least two light-emitting elements, thereby realizing at least two light-emitting elements connected in series. Moreover, the charge generation layer in a plurality of pixel units 103 may be a shared film layer. As shown in FIG3 , two pixel units 103 are shown, each of the two pixel units 103 includes two light-emitting elements, and the charge generation layer between the two light-emitting elements in each pixel unit 103 is shared. The charge generation layer in FIG2 includes an N-type charge generation layer (denoted as n-CGL) and a P-type charge generation layer (denoted as p-CGL).

[0069] In addition, referring to FIG. 2 and FIG. 3 , the plurality of pixel units 103 further include a common organic functional film layer 1031 , and the organic functional film layer 1031 includes at least a hole transport layer (HTL) and an electron transport layer (ETL).

[0070] Since each pixel unit 103 includes at least two stacked light-emitting elements, compared with each pixel unit 103 including one light-emitting element, the number of shared film layers is greater, the number of lateral leakage channels is greater, and the probability of lateral leakage is greater.

[0071] In order to solve the above technical problems, referring to Figure 1, the isolation layer 102 includes a plurality of isolation grooves U. The isolation groove U may refer to a groove at least provided in the isolation layer 102. Moreover, the isolation groove U may be located between two adjacent pixel units 103 in the plurality of pixel units 103. Since there is a certain height difference between the position where the isolation groove U is provided in the isolation layer 102 and the position where the isolation groove U is not provided, the common film layer (such as the organic functional film layer 1031 and the charge generation layer) in the plurality of pixel units 103 can be broken at the isolation groove U. Thus, by providing the isolation groove U, leakage current can be blocked by the isolation groove U, thereby reducing the probability of generating lateral leakage current. However, the provision of the isolation groove U may result in poor color deviation symmetry of the pixel unit 103, thereby affecting the display effect of the display panel 10.

[0072] Referring to Figure 1 , the plurality of pixel units 103 include at least a plurality of first color pixel units 103a. The first color pixel unit 103a includes at least a first side T1 and a second side T2 positioned opposite each other. An isolation groove U is provided on the first side T1, and an isolation groove U is provided on the second side T2. The isolation groove U provided on the first side T1 and the isolation groove U provided on the second side T2 are symmetrically arranged relative to the first color pixel unit 103a.

[0073] That is, isolation grooves are respectively provided on both sides of the first color pixel unit 103a, and the isolation grooves provided on both sides are symmetrically arranged, so that the symmetry of the isolation grooves U provided on the side edges of the first color pixel unit 103a can be improved, thereby improving the color deviation symmetry of the first color pixel unit 103a and improving the display effect of the display panel 10.

[0074] In summary, embodiments of the present application provide a display panel comprising a substrate, an isolation layer, and a plurality of pixel units. The isolation layer includes a plurality of isolation grooves, and the plurality of pixel units include a common organic functional film layer capable of breaking at the isolation grooves, i.e., leakage can be blocked by the isolation grooves, reducing the probability of lateral leakage. Furthermore, the isolation grooves located on the sides of the first color pixel unit are symmetrically arranged relative to the first color pixel unit, which can improve the color symmetry of the first color pixel unit and ensure the display effect of the display panel.

[0075] 1 , it can be seen that the plurality of pixel units 103 further include a plurality of second color pixel units 103b. Each second color pixel unit 103b is disposed adjacent to at least one first color pixel unit 103a.

[0076] The second color pixel unit 103b includes at least a third side T3 and a fourth side T4 that are positioned opposite each other. An isolation groove U is correspondingly provided on the third side T3, and an isolation groove U is correspondingly provided on the fourth side T4. The isolation groove U provided on the third side T3 and the isolation groove U provided on the fourth side T4 are symmetrically arranged relative to the second color pixel unit 103b.

[0077] That is, in addition to the symmetrical arrangement of the isolation grooves on both sides of the first color pixel unit 103a, the symmetrical arrangement of the isolation grooves on both sides of the second color pixel unit 103b is also achieved. This improves the color shift symmetry of not only the first color pixel unit 103a but also the second color pixel unit 103b, thereby enhancing the display quality of the display panel 10.

[0078] 1 , the plurality of pixel units 103 further include a plurality of third color pixel units 103c. Each third color pixel unit 103c is disposed adjacent to at least one first color pixel unit 103a, and a vertex of each third color pixel unit 103c is positioned opposite a vertex of at least one second color pixel unit 103b.

[0079] The third color pixel unit 103c includes at least a fifth side T5 and a sixth side T6 that are positioned opposite each other. An isolation groove U is provided on the fifth side T5, and an isolation groove U is provided on the sixth side T6. The isolation groove U provided on the fifth side T5 and the isolation groove U provided on the sixth side T6 are symmetrically arranged relative to the third pixel unit 103c.

[0080] That is, in the display panel 10, the isolation grooves provided on both sides of the first color pixel unit 103a, the isolation grooves provided on both sides of the second color pixel unit 103b, and the isolation grooves provided on both sides of the third color pixel unit 103c are all symmetrically arranged. This can improve the color shift symmetry of the first color pixel unit 103a, the second color pixel unit 103b, and the third color pixel unit 103c, thereby improving the display effect of the display panel 10.

[0081] In the embodiment of the present application, the plurality of pixel units 103 may include a plurality of red (red, R) pixel units, a plurality of green (green, G) pixel units, and a plurality of blue (blue, B) pixel units. Furthermore, the white light brightness of the display panel 10 is W = 0.2R + 0.7G + 0.1B. Here, R refers to the brightness of the red pixel unit, G refers to the brightness of the green pixel unit, and B refers to the brightness of the blue pixel unit. As can be seen from the above formula, the white light brightness mainly depends on the brightness of the green pixel unit.

[0082] Therefore, the viewing angle symmetry of white light is mainly determined by the viewing angle symmetry of the green pixel unit. That is, the better the viewing angle symmetry of the green pixel unit, the better the viewing angle symmetry of white light; the worse the viewing angle symmetry of the green pixel unit, the worse the viewing angle symmetry of white light.

[0083] For example, referring to Figures 4 and 5 , the more symmetrical the color shift curve of the green pixel unit is, the more symmetrical the color shift curve of the white light is, improving the viewing angle symmetry of the display panel 10 and achieving a better display effect. The JNCD in the vertical axis of Figures 4 and 5 is used to measure color accuracy.

[0084] Optionally, the following embodiment is described in detail by taking the first color pixel unit 103a as a green pixel unit, the second color pixel unit 103b as a blue pixel unit, and the third color pixel unit 103c as a red pixel unit as an example.

The first pixel unit group Z1 includes a plurality of first color pixel units 103 a and a plurality of second color pixel units 103 b arranged in a staggered manner along a second direction Y. The second pixel unit group Z2 includes a plurality of first color pixel units 103 a and a plurality of third color pixel units 103 c arranged in a staggered manner along the second direction Y. The second direction Y intersects the first direction X.

[0086] 6 and 7 , in the first pixel unit group Z1, a first target isolation groove U1 is defined between each first color pixel unit 103a and an adjacent second color pixel unit 103b. The two first target isolation grooves U1 located on two sides of the first color pixel unit 103a extending along the first direction X are symmetrically arranged relative to the first color pixel unit 103a. The two first target isolation grooves U1 located on two sides of the second color pixel unit 103b extending along the first direction X are symmetrically arranged relative to the second color pixel unit 103b.

[0087] 6 and 7 , in the second pixel unit group Z2, the two second target isolation grooves U2 located on the two side edges extending along the second direction Y of the first color pixel unit 103a are symmetrically arranged relative to the first color pixel unit; and the two third target isolation grooves U3 located on the two side edges extending along the second direction Y of the third color pixel unit 103c are symmetrically arranged relative to the third color pixel unit 103c.

[0088] 6 , the plurality of pixel units 103 constitute at least a third pixel unit group Z3 and a fourth pixel unit group Z4 that are arranged and adjacent to each other along the second direction Y. The third pixel unit group Z3 includes a plurality of first color pixel units 103 a and a plurality of second color pixel units 103 b that are arranged alternately along the first direction X. The fourth pixel unit group Z4 includes a plurality of first color pixel units 103 a and a plurality of third color pixel units 103 c that are arranged alternately along the first direction X.

[0089] 6 and 7 , in the third pixel unit group Z3, the two third target isolation grooves U3 located on the two side edges extending along the second direction Y of the first color pixel unit 103a are symmetrically arranged relative to the first color pixel unit 103a; and the two third target isolation grooves U3 located on the two side edges extending along the second direction Y of the second color pixel unit 103b are symmetrically arranged relative to the second color pixel unit 103b.

[0091] It should be noted that the plurality of pixel units 103 constituting the first pixel unit group Z1 and the second pixel unit group Z2, and the plurality of pixel units 103 constituting the third pixel unit group Z3 and the fourth pixel unit group Z4 are pixel unit groups divided in different directions.

In lines AA, CC, and DD, the organic functional film layer 1031 is broken at the isolation groove U.

[0093] In the solution shown in FIG1 , since the isolation groove U disposed on the side of the first color pixel unit 103a is only unilaterally symmetrical, the color shift symmetry of the first color pixel unit 103a is not very good. Furthermore, to improve the symmetry of the isolation groove U, the side of the first color pixel unit 103a can be bilaterally symmetrical.

[0094] Optionally, referring to FIG11 , the plurality of pixel units 103 comprise at least first color pixel units 103 a and second color pixel units 103 b arranged and adjacent to each other along the first direction X.

[0097] 11 , the plurality of pixel units 103 constitute at least a third pixel unit group Z3 and a fourth pixel unit group Z4, which are arranged and adjacent to each other along the second direction Y. The third pixel unit group Z3 includes a plurality of first color pixel units 103 a and a plurality of second color pixel units 103 b arranged in a staggered manner along the first direction X. The fourth pixel unit group Z4 includes a plurality of first color pixel units 103 a and a plurality of third color pixel units 103 c arranged in a staggered manner along the first direction X.

[0098] 11 and 12 , in the third pixel unit group Z3, a seventh target isolation groove U7 is provided between each first color pixel unit 103a and an adjacent second color pixel unit 103b, and a sixth target isolation groove U6 is provided on both sides of each first color pixel unit 103a extending along the first direction X. The two seventh target isolation grooves U7 provided on both sides of the first color pixel unit 103a extending along the second direction Y are symmetrically arranged relative to the first color pixel unit 103a; the two seventh target isolation grooves U7 provided on both sides of the second color pixel unit 103b extending along the second direction Y are symmetrically arranged relative to the second color pixel unit 103b; and the two sixth target isolation grooves U6 provided on both sides of the first color pixel unit 103a extending along the first direction X are symmetrically arranged relative to the first color pixel unit 103a.

[0099] 11 and 12 , in the fourth pixel unit group, a fifth target isolation groove U5 is provided between each first color pixel unit 103a and an adjacent third color pixel unit 103c, and a fourth target isolation groove U4 is provided on both sides of each first color pixel unit 103a extending along the second direction Y. The two fifth target isolation grooves U5 provided on both sides of the first color pixel unit 103a extending along the second direction Y are symmetrically arranged relative to the first color pixel unit 103a; the two sixth target isolation grooves U6 provided on both sides of the third color pixel unit 103c extending along the first direction X are symmetrically arranged relative to the third color pixel unit 103c; and the two fourth target isolation grooves U4 provided on both sides of the first color pixel unit 103a extending along the first direction X are symmetrically arranged relative to the first color pixel unit 103a.

[0100] 11 and 12 , it can be seen that an isolation groove U is provided between any two adjacent pixel units 103 , thereby preventing lateral crosstalk between any adjacent pixel units 103 and improving display effects.

[0101] Furthermore, for the first color pixel unit 103a, the isolation groove is bilaterally symmetrical with respect to the first color pixel unit 103a, thereby improving the color shift symmetry of the first color pixel unit 103a and further improving the viewing angle symmetry of white light.

[0102] 11 , the isolation grooves are also bilaterally symmetrical for the second color pixel unit 103b and the third color pixel unit 103c, thereby improving the color shift symmetry of the second color pixel unit 103b and the third color pixel unit 103c and further enhancing the viewing angle symmetry of white light.

[0103] In addition, referring to Figure 11, the top corner of the third color pixel unit 103c and the top corner of the second color pixel unit 103b are arranged opposite to each other, and no isolation groove U is set between the top corner of the third color pixel unit 103c and the top corner of the second color pixel unit 103b, which may cause the third color pixel unit 103c and the second color pixel unit 103b to crosstalk with each other at the top corner position.

[0104] Therefore, to solve the above technical problems, referring to Figures 13 and 14, each third color pixel unit 103c includes a first vertex corner and a second vertex corner positioned opposite each other. An isolation groove is provided at the first vertex corner, and an isolation groove is provided at the second vertex corner. The isolation groove U provided at the first vertex corner and the isolation groove U provided at the second vertex corner are symmetrically arranged relative to the third color pixel unit 103c.

[0105] 13 and 14 , it can be seen that the isolation groove disposed at the top corner of the third color pixel unit 103c is located on the side away from the third color pixel unit 103c, which is the second color pixel unit 103b. In other words, an eighth target isolation groove U8 is provided between the top corner of the third color pixel unit 103c and the top corner of the second color pixel unit 103b.

[0106] In the embodiment of the present application, because the design of the isolation groove U reduces the signal path, the voltage required by the pixel unit 103 increases when the pixel unit 103 reaches the same current density, which may lead to increased power consumption of the product. Generally, the greater the distance between the isolation groove U and the pixel unit 103, the smaller the impact on the voltage required by the pixel unit 103; the smaller the distance between the isolation groove U and the pixel unit 103, the greater the impact on the voltage required by the pixel unit 103.

[0107] Therefore, in the embodiment of the present application, the setting position of the isolation groove U between two adjacent pixel units 103 can be determined based on the magnitude relationship of the voltages required by the two pixel units 103 under the same current density. Optionally, the distance between the isolation groove U and the pixel unit 103 can be positively correlated with the voltage required by the pixel unit 103. That is, the greater the voltage required by the pixel unit 103, the greater the distance between the isolation groove U and the pixel unit 103; the smaller the voltage required by the pixel unit 103, the smaller the distance between the isolation groove U and the pixel unit 103. For example, the isolation groove U can be designed to be closer to the pixel unit 103 with a smaller required voltage, that is, the distance between the isolation groove U and the pixel unit 103 with a smaller required voltage is smaller than the distance between the isolation groove U and the pixel unit 103 with a larger required voltage.

[0108] Optionally, under the same current density, the voltage required by the second color pixel unit 103b is greater than the voltage required by the first color pixel unit 103a. That is, the second color pixel unit 103b is more susceptible to the influence of the isolation groove U than the first color pixel unit 103a.

[0109] In the embodiment of the present application, referring to FIG1 , for the isolation groove U located between the second color pixel unit 103b and the first color pixel unit 103a, the distance h1 between the isolation groove U and the first color pixel unit 103a is less than the distance h2 between the isolation groove U and the second color pixel unit 103b. Thus, the effect of the isolation groove U on the second color pixel unit 103b can be minimized, preventing the voltage required by the second color pixel unit 103b from being significantly increased due to the provision of the isolation groove U, and minimizing the effect of the isolation groove U on the increased power consumption of the product.

[0110] Furthermore, the distance between the second color pixel unit 103b and the first target isolation groove, and the distance between the other pixel units and the second target isolation groove, can be determined based on the voltage required by the second color pixel unit 103b and the other pixel units under the same current density. The first target isolation groove is located on the side of the second color pixel unit 103b, and the second target isolation groove is located on the side of the other pixel units. The other pixel units may be, for example, the first color pixel unit 103a and the third color pixel unit 103c.

[0111] Optionally, under the same current density, the voltage required by the second color pixel unit 103b is greater than the voltage required by the other pixel units except the second color pixel unit 103b in the plurality of pixel units 103. Therefore, the distance between the second color pixel unit 103b and the first target isolation groove is greater than the distance between the other pixel units and the second target isolation groove.

[0112] In the embodiment of the present application, referring to FIG. 15 , under the same current density, the voltage required by the blue pixel unit is greater than the voltage required by the green pixel unit, and the voltage required by the green pixel unit is greater than the voltage required by the red pixel unit.

[0113] For example, the first color pixel unit 103a may be a green pixel unit, the second color pixel unit 103b may be a blue pixel unit, and the third color pixel unit 103c may be a red pixel unit.

[0114] 14 , an eighth isolation groove U8 is located between the top corner of the third color pixel unit 103c and the top corner of the second color pixel unit 103b. Since the voltage required by the second color pixel unit 103b is greater than that required by the third color pixel unit 103c under the same current density, to prevent the design of the isolation groove U from significantly affecting the second color pixel unit 103b, the distance between the eighth isolation groove U8 and the third color pixel unit 103c can be smaller than the distance between the eighth isolation groove U8 and the second color pixel unit 103b.

[0115] In the embodiment of the present application, referring to FIG1 , the orthographic projection of the isolation groove U on the base substrate 101 is in the shape of a bar. Each isolation groove U has a gap between it and other isolation grooves U in the extension direction of the isolation groove U, and the organic functional film layer 1031 is continuous at the gap.

[0116] Optionally, the orthographic projection of the isolation groove U on the base substrate 101 may also be in other shapes, as long as the organic functional film layer 1031 can be broken at the isolation groove U.

[0117] Furthermore, referring to FIG1 , the orthographic projection of the side of the isolation groove U away from the base substrate 101 on the base substrate 101 is located within the orthographic projection of the side of the isolation groove U close to the base substrate 101 on the base substrate 101. The area of ​​the orthographic projection of the side of the isolation groove U away from the base substrate 101 on the base substrate 101 is smaller than the area of ​​the orthographic projection of the side of the isolation groove U close to the base substrate 101 on the base substrate 101.

[0118] For example, the orthographic projection of the isolation groove U on the reference plane may be an inverted trapezoid. The reference plane is perpendicular to the supporting surface of the base substrate 101 and perpendicular to the extension direction of the isolation groove U. Of course, the orthographic projection of the isolation groove U on the reference plane may also be other shapes, as long as the size of the isolation groove U is smaller at the top and larger at the bottom.

[0119] In the embodiment of the present application, referring to Figures 2, 8 to 10, and 16, the display panel 10 further includes a planarization layer 104 located between the base substrate 101 and the isolation layer 102.

The first groove portion is located in the isolation layer 102, and the second groove portion is located in the planarization layer 104.

[0120] Optionally, the process of forming the isolation groove U includes: forming a flat film and an isolation film on one side of the base substrate 101; etching the isolation film using a dry etching process or a wet etching process; and continuing to etch the flat film using a dry etching process or a wet etching process.

[0121] It should be noted that the depth of the isolation groove U can be controlled by controlling the etching time of the etching process. The deeper the depth of the isolation groove U, the better the fracture effect of the organic functional film layer 1031 at the isolation groove U. Optionally, the depth of the isolation groove U ranges from 0.1 μm (micrometer) to 0.5 μm.

[0122] 2 , 8 to 10 and 16 , the pixel unit 103 includes an anode layer 1032 , a pixel defining layer 1033 , a light emitting layer (not shown), an organic functional film layer 1031 and a cathode layer 1034 .

The orthographic projections of the anode patterns 10321 on the base substrate 101 do not overlap with the orthographic projections of the isolation grooves U on the base substrate 101.

[0124] The pixel defining layer 1033 is located on a side of the anode layer 1032 away from the base substrate 101 and has a first hollow region 1033a and multiple second hollow regions 1033b. Each first hollow region 1033a exposes at least a portion of an anode pattern 10321, and each second hollow region 1033b exposes an isolation groove U.

[0125] The light emitting layer is located in the first hollow area 1033 a , the organic functional film layer 1031 is located in the first hollow area 1033 a and the second hollow area 1033 b , and the organic functional film layer 1031 is continuous in other areas except the isolation groove U.

[0126] The cathode layer 1034 is located in the first hollow area 1033 a and the second hollow area 1033 b . The cathode layer 1034 is broken at the isolation groove U, and the film layer is continuous in other areas except the isolation groove U.
