DETAILED DESCRIPTION

[0083] The following detailed description and drawings of the embodiments of the present application are used to illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0084] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating the orientation or positional relationship, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly vertical, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0085] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0086] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0087] With the development of process technology and the increasing demand for the use of display devices, new display technologies such as UDC (Universal Display Corp, under-screen camera) technology and new product forms such as transparent screens and stretch screens have emerged. UDC technology is about hiding the camera under the screen, thereby eliminating the "bangs" area or punching area corresponding to the front camera to achieve a true full screen. Transparent screen, also known as transparent display screen, is a new type of display technology that allows the display screen to remain transparent while displaying images. This technology can display images and text without affecting the background landscape. Stretching screen, that is, the screen can be stretched and deformed as needed to achieve display effects of different sizes and proportions. UDC technology, transparent screen, stretching screen and other related technologies require the display screen to have high transmittance.

[0088] Currently, in some display panels, multiple first isolation structures can be designed in the UDC area to independently isolate multiple sub-pixels, that is, a first isolation structure is arranged around the outer periphery of each sub-pixel, resulting in a larger coverage area of ​​the first isolation structure, affecting the light transmittance of the display panel.

[0089] An embodiment of the present application provides a display panel, which may be an organic light emitting diode (OLED) display panel, or other types of display panels, such as a micro light emitting diode (Micro Light Emitting Diode, Micro-LED) or a quantum dot light emitting diode (Quantum Light Emitting Diode, QLED) display panel.

[0090] Please refer to Figure 1 and Figure 2 In a first aspect, the present application provides a display panel 100, comprising a substrate 10, a plurality of first isolation structures 20 and a plurality of first pixel units 30; the first isolation structure 20 is arranged on one side of the substrate 10, a light-transmitting area AA is formed between the plurality of first isolation structures 20, and the first isolation structures 20 enclose at least two first isolation openings 21; the first pixel unit 30 comprises at least two first sub-pixels 311, and each first sub-pixel 311 of the same first pixel unit 30 is located in each first isolation opening 21 of the same first isolation structure 20.

[0091] The substrate 10 includes a substrate and a driving circuit layer arranged on the substrate. The substrate can be a hard substrate made of materials such as glass or plastic, or a flexible substrate made of materials such as polyethersulfone (PES), polyacrylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyarylate, polyimide (PI), polycarbonate (PC) or cellulose acetate propionate (CAP). A driving circuit for controlling the light emission of the first pixel unit 30 is arranged in the driving circuit layer. The driving circuit layer is generally composed of inorganic film layers such as a metal layer, a semiconductor layer (active layer), and an insulating layer. By patterning these inorganic film layers, a driving circuit for controlling the light emission of the first pixel unit 30 can be formed. There are many implementation methods for its specific circuit structure, which will not be repeated here.

[0092] The first isolation structure 20 is disposed on one side of the substrate 10, and there are multiple first isolation structures 20. The area between the multiple first isolation structures 20 has a high light transmittance, forming a light-transmitting area AA. The first isolation structure 20 can be used to separate the first pixel material into first sub-pixels 311, so that each first sub-pixel 311 is located in the corresponding first isolation opening 21, and no mask is required to prepare the first pixel unit 30, which can save costs. Among the multiple first isolation structures 20, each first isolation structure 20 encloses at least two first isolation openings 21, and the number and shape of the first isolation openings 21 enclosed by different first isolation structures 20 can be the same or different, and the shape of the first isolation openings 21 in the same first isolation structure 20 can be the same or different, and this embodiment does not limit this.

[0093] It can be understood that in the related art, an independent first isolation structure 20 is arranged around the outer peripheral side of each first sub-pixel 311. Therefore, there are usually two first isolation structures 20 between two adjacent first sub-pixels 311, resulting in a larger coverage area of ​​the first isolation structure 20, which affects the transmittance of the display panel 100.

[0094] In view of this, in these embodiments, each first pixel unit 30 includes at least two first sub-pixels 311, wherein multiple first pixel units 30 are arranged in a one-to-one correspondence with multiple first isolation structures 20, and each first sub-pixel 311 of the same first pixel unit 30 is arranged in each first isolation opening 21 of the same first isolation structure 20. Therefore, in the same first pixel unit 30, two adjacent first sub-pixels 311 can share part of the first isolation structure 20, thereby reducing the width of the first isolation structure 20 between the two adjacent first sub-pixels 311, reducing the coverage area of ​​the first isolation structure 20, and improving the transmittance of the display panel 100.

[0095] In some embodiments, a plurality of first isolation structures 20 are arranged at intervals to form a light-transmitting area AA between two adjacent first isolation structures 20 , which can improve the light transmittance of the display panel 100 .

[0096] Preferably, the edge profile of the orthographic projection of the first isolation opening 21 on the substrate 10 is at least partially arc-shaped.

[0097] It should be noted that the opening area of ​​the first isolation opening 21 affects the light emitting effect of the first sub-pixel 311. The larger the opening area of ​​the first isolation opening 21, the better the light emitting effect of the first sub-pixel 311. However, the larger the opening area of ​​the first isolation opening 21, the larger the size of the first isolation structure 20, and the larger its coverage area, thereby affecting the light transmittance of the display panel 100. Therefore, in order to improve the light emitting effect of the first sub-pixel 311 and make the display panel 100 have good light transmittance, the opening area of ​​the first isolation opening 21 can be reasonably set. On this basis, in this embodiment, by setting the edge contour of the orthographic projection of the first isolation opening 21 on the substrate 10 to be at least partially arc-shaped, the perimeter of the first isolation opening 21 can be reduced on the basis of ensuring that the first isolation opening 21 has a larger opening area, that is, the size of the first isolation structure 20 used to enclose the first isolation opening 21 is reduced, thereby reducing the coverage area of ​​the first isolation structure 20.

[0098] Please continue reading Figure 1 Preferably, the orthographic projection of the first isolation opening 21 on the substrate 10 is circular, so as to further reduce the perimeter of the first isolation opening 21 when the opening area is the same. Preferably, the orthographic projection areas of the first isolation openings 21 on the substrate 10 are the same, so that the areas of the first sub-pixels 311 in the first isolation openings 21 are the same, thereby further improving the light transmittance and enabling the display panel 100 to emit light uniformly.

[0099] Preferably, the shape of the orthographic projection of the first sub-pixel 311 on the substrate 10 is circular, so as to reduce the perimeter of the first sub-pixel 311 under the same area, thereby reducing the coverage area of ​​the first sub-pixel 311 and improving the light transmittance of the display panel 100. In addition, the circular structural design is conducive to ensuring the display effect of the display panel 100.

[0100] See also Figure 3 Preferably, each first isolation structure 20 encloses three first isolation openings 21, and at least two first sub-pixels 311 include a first red sub-pixel 311a, a first green sub-pixel 311b and a first blue sub-pixel 311c; the first red sub-pixel 311a, the first green sub-pixel 311b and the first blue sub-pixel 311c are respectively located in the corresponding first isolation openings, thereby realizing color display of the display panel.

[0101] It should be noted that each first isolation structure encloses three first isolation openings, in which the first red sub-pixel 311a, the first green sub-pixel 311b and the first blue sub-pixel 311c can be respectively arranged, so that the first red sub-pixel 311a, the first green sub-pixel 311b and the first blue sub-pixel 311c are evenly distributed in each first isolation structure.

[0102] See also Figure 3 and Figure 4 Preferably, the at least two first sub-pixels include a first red sub-pixel 311a, a first green sub-pixel 311b and a first blue sub-pixel 311c; in the same first pixel unit, the number of the first red sub-pixel 311a, the first green sub-pixel 311b and the first blue sub-pixel 311c is the same, so that the first sub-pixels 311 of each color in the first pixel unit 30 are distributed as evenly as possible, so that the display panel 100 emits light evenly.

[0103] It should be noted that the present embodiment does not limit the number of the first red sub-pixel 311a, the first green sub-pixel 311b, and the first blue sub-pixel 311c in the same first pixel unit 30. For example, the first sub-pixels 311 of each color in the same first pixel unit 30 may be as follows: Figure 3 As shown in Figure 1, it can also be Figure 4 Two are shown.

[0104] Please continue reading Figure 1 In some embodiments, in the same first isolation structure 20 , at least two first isolation openings 21 are adjacently arranged, and the two first isolation openings 21 share part of the first isolation structure 20 to reduce the coverage area of ​​the first isolation structure 20 and improve the light transmittance of the display panel 100 .

[0105] It should be noted that the two first isolation openings 21 share part of the first isolation structure 20, which means that the part of the first isolation structure 20 can be combined with a part of the first isolation structure 20 to form a first isolation opening 21, and can also be combined with other parts of the first isolation structure 20 to form another adjacent first isolation opening 21. In other words, only one first isolation structure 20 is required between two adjacent first isolation openings 21. Compared with setting two adjacent first isolation openings 21 to be formed by separately enclosing the corresponding first isolation structures 20, so that there are two first isolation structures 20 between the two adjacent first isolation openings 21, the coverage area of ​​the first isolation structure 20 between the two first isolation openings 21 can be reduced.

[0106] Preferably, in the same first isolation structure 20 , any two first isolation openings 21 are arranged adjacent to each other, and any two first isolation openings 21 share a portion of the first isolation structure 20 .

[0107] In these embodiments, any two first isolation openings 21 in the same first isolation structure 20 are arranged adjacent to each other, so that any two first isolation openings 21 in the same first isolation structure 20 can share part of the first isolation structure 20 , which can further reduce the coverage area of ​​the first isolation structure 20 .

[0108] Preferably, each first isolation structure 20 encloses and forms three first isolation openings 21, so that any two first isolation openings 21 in the same first isolation structure 20 are arranged adjacent to each other, that is, any two first isolation openings 21 in the same first isolation structure 20 share part of the first isolation structure 20, thereby reducing the coverage area of ​​the first isolation structure 20. Each first pixel unit 30 includes three first sub-pixels 311, and the three first sub-pixels 311 are arranged one-to-one in the three first isolation openings 21, so that the first sub-pixels 311 in each first pixel unit 30 can be isolated by the first isolation structure 20.

[0109] In some embodiments, in the same first isolation structure 20, the minimum distance between at least two adjacent first isolation openings 21 is less than or equal to 24 microns. For example, the minimum distance may be 5 microns, 7 microns, 8 microns, 10 microns, 12 microns, 14 microns, 20 microns, 24 microns, etc., so that the minimum width of the first isolation structure 20 located between the two adjacent first isolation openings 21 is less than or equal to 24 microns, so as to reasonably set the minimum width of the first isolation structure 20 located between the two adjacent first isolation openings 21 and reduce the coverage area of ​​the first isolation structure 20.

[0110] Preferably, in the same first isolation structure 20, the minimum distance between any two adjacent first isolation openings 21 is less than or equal to 24 microns. For example, the minimum distance may be 5 microns, 7 microns, 8 microns, 10 microns, 12 microns, 15 microns, 24 microns, etc., so that the minimum width of the first isolation structure 20 between any two adjacent first isolation openings 21 in the same first isolation structure 20 is less than or equal to 24 microns, thereby further adjusting the minimum width of the first isolation structure 20 between two adjacent first isolation openings 21 and reducing the coverage area of ​​the first isolation structure 20.

[0111] Preferably, in the same first isolation structure 20, the minimum distance between any two adjacent first isolation openings 21 is less than or equal to 12 microns, for example, it can be 3 microns, 4 microns, 5 microns, 7 microns, 8 microns, 10 microns, 12 microns, etc., so as to further adjust the minimum width of the first isolation structure 20 between any two adjacent first isolation openings 21 in the same first isolation structure 20 and reduce the coverage area of ​​the first isolation structure 20.

[0112] In some embodiments, in the same first isolation structure 20, the distance between the centroids of at least two adjacent first isolation openings 21 is D, R1+R2+d≤D≤R1+R2+2d, where R1 and R2 are the distances from the centroid to the edge of the corresponding first isolation opening 21, and d is the minimum width of the first isolation structure 20.

[0113] The centroid of the first isolation opening 21 mentioned in the present application refers to the geometric center of the first isolation opening 21. R1 and R2 are distances from the centroids of two adjacent first isolation openings 21 to the edges of the corresponding first isolation openings 21.

[0114] In these embodiments, by reasonably setting the distance between the centroids of at least two adjacent first isolation openings 21 in the same first isolation structure 20, the width of the first isolation structure 20 located between the two adjacent first isolation openings 21 can be reasonably designed, so that the width of the first isolation structure 20 located between the two adjacent first isolation openings 21 is greater than or equal to the minimum width of the first isolation structure 20, and less than or equal to twice the minimum width of the first isolation structure 20, thereby reducing the coverage area of ​​the first isolation structure 20 located between the two adjacent first isolation openings 21.

[0115] Preferably, in the same first isolation structure 20, the distance between the centroids of any two adjacent first isolation openings 21 is D, and the width of the first isolation structure 20 between any two adjacent first isolation openings 21 in the same first isolation structure 20 can be reasonably set to reduce its coverage area.

[0116] Preferably, the orthographic projection of the first isolation opening 21 on the substrate 10 is in a circular shape, so as to reduce the perimeter of the first isolation opening 21 while keeping the area the same, and further reduce the coverage area of ​​the first isolation structure 20 .

[0117] Preferably, in the same first isolation structure 20, the distance between the centroids of any two adjacent first isolation openings 21 is D, and R1+R2+d=D, where d≤12 microns, so that the width of the first isolation structure 20 between any two adjacent first isolation openings 21 in the same first isolation structure 20 is less than or equal to 12 microns, which can further reduce the coverage area of ​​the first isolation structure 20.

[0118] It should be noted that d is less than or equal to 12 micrometers. For example, d may be 3 micrometers, 5 micrometers, 7 micrometers, 8 micrometers, 10 micrometers, 12 micrometers, etc.

[0119] In some specific embodiments, since the shape of the positive projection of the first isolation opening 21 on the substrate 10 is circular, and the projection areas of each first isolation opening 21 are the same, the first isolation structure 20 surrounds each first isolation opening 21, that is, the first isolation structure 20 is formed by a plurality of annular connections, so that the width of the first isolation structure 20 at the centroid connection area between two adjacent first isolation openings 21 is the smallest, and the width on both sides thereof becomes larger and larger.

[0120] Preferably, each first isolation structure 20 encloses three first isolation openings 21, and each first pixel unit 30 includes a first red sub-pixel 311a, a first green sub-pixel 311b and a first blue sub-pixel 311c, and the first red sub-pixel 311a, the first green sub-pixel 311b and the first blue sub-pixel 311c are respectively located in the corresponding first isolation openings 21, thereby realizing color display of the display panel 100.

[0121] Preferably, the orthographic projection of the first isolation structure 20 on the substrate 10 covers the area between the three first isolation openings 21, and the three first isolation openings 21 belong to the same first isolation structure 20. Therefore, when R1+R2+d=D and d≤12 microns, the width of the first isolation structure 20 between any two first isolation openings 21 of the three first isolation openings 21 formed by the same first isolation structure 20 is less than or equal to 12 microns, so as to further reduce the coverage area of ​​the first isolation structure 20.

[0122] See also Figure 2 In some embodiments, the distance between two adjacent first pixel units 30 is greater than the distance between any two adjacent first sub-pixels 311 in the first pixel unit 30 .

[0123] Specifically, multiple first pixel units 30 are arranged in one-to-one correspondence with multiple first isolation structures 20. Therefore, the distance between two adjacent first pixel units 30 is greater than the distance between any two adjacent first sub-pixels 311 in the first pixel unit 30, which can increase the gap between two adjacent first isolation structures 20, thereby improving the light transmittance effect of the display panel 100.

[0124] It should be noted that the distance between two adjacent first pixel units 30 may be the minimum distance between the first sub-pixels 311 in two adjacent first pixel units 30, that is, the minimum distance from the first sub-pixel 311 in one first pixel unit 30 to the first sub-pixel 311 in another adjacent first pixel unit 30. The distance between any two adjacent first sub-pixels 311 in a first pixel unit 30 refers to the distance between any two adjacent first sub-pixels 311 in the same first pixel unit 30.

[0125] Please continue reading Figure 2 Preferably, the display panel 100 also includes a pixel definition layer 40, which is arranged between the substrate 10 and the first isolation structure 20, and the pixel definition layer 40 includes a pixel defining portion 41 and a plurality of first pixel openings 42 formed by the pixel defining portion 41, and the first pixel openings 42 are connected to the corresponding first isolation openings 21.

[0126] The pixel definition layer 40 is disposed between the substrate 10 and the first isolation structure 20, that is, the first isolation structure 20 is disposed on the side of the pixel definition layer 40 away from the substrate 10. The pixel definition layer 40 includes a pixel defining portion 41 and a plurality of first pixel openings 42 formed by the pixel defining portion 41, and each first pixel opening 42 is correspondingly connected to each first isolation opening 21, so that each first isolation opening 21 has a large height difference. When preparing the first sub-pixel 311, due to the large height difference at the first isolation opening 21, the material of the first pixel unit 30 is more easily disconnected at the first isolation structure 20, thereby reducing the difficulty of preparation.

[0127] Preferably, the orthographic projection of the first pixel opening 42 on the substrate 10 is located within the orthographic projection of the corresponding first isolation opening 21 on the substrate, so that the first pixel opening 42 is connected to the corresponding first isolation opening 21. The distance between the two adjacent first pixel units 30 is greater than the distance between any two adjacent first sub-pixels 311 in the first pixel unit 30, which can also be understood as follows: the distance between the two adjacent first pixel units 30 can be the minimum distance between the first pixel openings 42 in the two adjacent first pixel units 30, that is, the minimum distance from the first pixel opening 42 in one first pixel unit 30 to the first pixel opening 42 in another adjacent first pixel unit 30; the distance between any two adjacent first sub-pixels 311 in the first pixel unit 30 can be the distance between any two adjacent first pixel openings 42 in the first pixel unit 30.

[0128] Preferably, the material of the pixel definition layer 40 includes an inorganic material, so that the pixel definition layer 40 can be made lighter and thinner when the pixel definition layer 40 is prepared.

[0130] Specifically, the first electrode 312 can be arranged on one side of the substrate 10, and it is electrically connected to the thin film transistor of the driving circuit layer. The first light-emitting functional layer 313 is arranged on the side of the first electrode 312 away from the substrate 10. The first light-emitting functional layer 313 can be formed by stacking multiple film layers. For example, the first light-emitting functional layer 313 can include a stacked hole injection layer (Hole Inject Layer, HIL), a hole transport layer (Hole Transport Layer, HTL), a light-emitting layer, an electron injection layer (Electron Inject Layer, EIL) and an electron transport layer (Electron Transport Layer, ETL). The second electrode 314 is arranged on the side of the first light-emitting functional layer 313 away from the substrate 10. The second electrodes 314 of the plurality of first sub-pixels 311 can be electrically connected to each other to form a whole surface electrode, or can be insulated from each other.

[0131] Please continue reading Figure 2 Preferably, the material of the first isolation structure 20 includes a conductive material. In each first pixel unit 30, the second electrodes 314 of two adjacent first sub-pixels 311 are electrically connected through the first isolation structure 20, and the first electrodes 312 of the first sub-pixels 311 are insulated from the first isolation structure 20, that is, they are insulated by the pixel definition layer 40.

[0132] In these embodiments, in each first pixel unit 30, the second electrodes 314 of two adjacent first sub-pixels 311 are electrically connected through the first isolation structure 20, so that the first sub-pixels 311 in the same first pixel unit 30 can be driven simultaneously to improve the display effect. The first electrode 312 of the first sub-pixel 311 is insulated from the first isolation structure 20, which can prevent the first electrode 312 and the second electrode 314 of the first sub-pixel 311 from being short-circuited through the first isolation structure 20, thereby ensuring that each first sub-pixel 311 emits light normally.

[0133] In some embodiments, among the plurality of first sub-pixels 311 , the first electrodes 312 of at least some of the first sub-pixels 311 with the same color are electrically connected to each other, so that the first electrodes 312 of the first sub-pixels 311 can be driven simultaneously.

[0134] See also Figure 5 Preferably, the display panel 100 also includes a first conductive line 90. Among the multiple first sub-pixels 311, the first electrodes 312 of at least some of the first sub-pixels 311 with the same color are electrically connected through the first conductive line 90, which can reduce the space occupied by these first sub-pixels 311 and improve the light transmission effect.

[0135] It should be noted that the first conductive line 90 may be located in the pixel defining portion 41 or between the pixel defining portion 41 and the substrate 10 , and the first conductive line 90 may extend along a straight line or a curve, which is not limited in this embodiment.

[0136] Preferably, the first electrodes 312 of 2-6 first sub-pixels 311 of the same color are electrically connected through the first conductive line 90, so the 2-6 first sub-pixels 311 of the same color can be driven simultaneously to improve the performance of the display panel 100. For example, the first electrodes 312 of 2, 3, 4, 5 or 6 first sub-pixels 311 of the same color can be electrically connected through the first conductive line 90.

[0137] Specifically, among the multiple first sub-pixels 311, the first electrodes 312 of 2-6 first sub-pixels 311 with the same color are electrically connected through a first conductive line 90, and the first electrodes 312 of the remaining first sub-pixels 311 can be insulated from each other, or, the first electrodes 312 of 2-6 first sub-pixels 311 with the same color among the remaining first sub-pixels 311 can be electrically connected through another first conductive line 90.

[0138] Preferably, the material of the first conductive line 90 includes a light-transmitting conductive material to further improve the light-transmitting effect.

[0139] Preferably, the material of the first conductive line 90 includes ITO, so that the first conductive line 90 has good light transmission performance.

[0143] Preferably, the material of the second conductive line 50 includes ITO, so that the second conductive line 50 has good light transmission performance.

[0144] See also Figure 6 In some embodiments, the display panel 100 includes a first display area A1 and a second display area A2, the transmittance of the first display area A1 is greater than the transmittance of the second display area A2, and the first isolation structure 20 and the first pixel unit 30 are both located in the first display area A1, thereby further improving the transmittance of the first display area A1.

[0145] It should be noted that the first display area A1 may be a UDC area, that is, an area in the display panel 100 for setting an under-screen camera. It is understandable that in this embodiment, the second display area A2 is a main display area for achieving a main display effect, and a first isolation structure 20 and a first pixel unit 30 are provided in the first display area A1. When the display panel 100 displays an image, the first pixel unit 30 in the first display area A1 may emit light and play a role in auxiliary display, so that the display panel 100 can achieve full-screen display.

[0147] In these embodiments, the second isolation structure 60 can be entirely disposed on one side of a portion of the substrate 10 corresponding to the second display area A2, and enclosed to form a second isolation opening 61. Therefore, the second pixel material can be separated into second sub-pixels 711 by the second isolation structure 60, so that the second sub-pixel 711 is located in the corresponding second isolation opening 61, and no mask is required to prepare the second pixel unit 70, which can save the use of the mask and save costs.

[0148] It should be noted that, in this embodiment, the second pixel unit 70 may include a plurality of second sub-pixels 711, and each second sub-pixel 711 of each second pixel unit 70 is respectively disposed in each second isolation opening 61 of the second isolation structure 60, that is, the plurality of second sub-pixels 711 in the second pixel unit 70 are disposed in one-to-one correspondence with the plurality of second isolation openings 61 of the second isolation structure 60. The plurality of second sub-pixels 711 may be second sub-pixels 711 of different colors, such as red, blue, green, etc.

[0149] See also Figure 7 In some optional embodiments, the second isolation structure 60 is arranged on the side of the pixel defining portion 41 away from the substrate 10, and the pixel defining portion 41 also encloses a plurality of second pixel openings 43, and the second pixel openings 43 are connected to the corresponding second isolation openings 61. When preparing the second sub-pixel 711, the second pixel 71 material is more easily disconnected at the second isolation structure 60, thereby reducing the difficulty of preparation.

[0151] Specifically, the third electrode 712 is arranged on one side of the substrate 10, and is electrically connected to the thin film transistor of the driving circuit layer. The second light-emitting functional layer 713 is arranged on the side of the third electrode 712 away from the substrate 10. The second light-emitting functional layer 713 can be formed by stacking multiple film layers. For example, the second light-emitting functional layer 713 can include a stacked hole injection layer (Hole Inject Layer, HIL), a hole transport layer (Hole Transport Layer, HTL), a light-emitting layer, an electron injection layer (Electron Inject Layer, EIL) and an electron transport layer (Electron Transport Layer, ETL). The fourth electrode 714 is arranged on the side of the second light-emitting functional layer 713 away from the substrate 10. The fourth electrodes 714 of the plurality of second sub-pixels 711 can be electrically connected to each other to form a whole surface electrode, or can be insulated from each other. After the third electrode 712 and the fourth electrode 714 are energized, the third electrode 712 can be used as an anode, the fourth electrode 714 can be used as a cathode, and the thin film transistor can drive the second sub-pixel 711 to emit light.

The third electrode 712 is insulated from the second isolation structure 60, thereby preventing the third electrode 712 and the fourth electrode 714 from being short-circuited through the second isolation structure 60.

[0154] See also Figure 7 Preferably, the third electrodes 712 of two adjacent second sub-pixels 711 are insulated from each other, so that the third electrodes 712 of a plurality of second sub-pixels 711 can be driven individually to reduce crosstalk.

[0155] Preferably, the orthographic projection of the second isolation structure 60 on the substrate 10 is in a mesh shape, so that the second sub-pixels 711 are arranged compactly, so as to set as many second sub-pixels 711 as possible in a limited space, thereby improving the light extraction effect of the display panel 100 .

[0156] In some embodiments, the area of ​​the orthographic projection of the first isolation opening 21 on the substrate 10 is less than or equal to the area of ​​the orthographic projection of at least part of the second isolation opening 61 on the substrate 10, so as to reduce the opening area of ​​the first isolation opening 21, reduce the space occupied by the first isolation opening 21 and the first sub-pixel 311 located in the first isolation opening 21 in the first display area A1, and improve the transmittance of the first display area A1.

[0159] Preferably, the shape of the orthographic projection of the second isolation opening 61 on the substrate 10 is rectangular. Compared with setting the shape of the orthographic projection of the second isolation opening 61 on the substrate 10 to be circular, the opening area of ​​the second isolation opening 61 can be increased, thereby increasing the pixel density of the second sub-pixel 711 located in the second isolation opening 61, and improving the luminous effect of the display panel 100.

[0160] In some embodiments, the first isolation structure 20 and the second isolation structure 60 are electrically connected, so that the second electrode 314 of each first sub-pixel 311 in the first pixel unit 30 and the fourth electrode 714 of each second sub-pixel 711 in the second pixel unit 70 can be electrically connected to each other to form a full-surface electrode to further improve the display effect.

Therefore, when the first pixel material is formed on the side of the first isolation structure 20 away from the substrate 10, the second isolation portion 23 can separate the second pixel material to form a first sub-pixel 311, so that the first sub-pixel 311 is located in the first isolation opening 21, and there is no need to use a mask to prepare the first pixel unit 30, which can save costs.

[0170] Please continue reading Figure 6 According to a second aspect of the present application, a display panel 100 is provided. The display panel 100 includes a first display area A1 and a second display area A2. The transmittance of the first display area A1 is greater than the transmittance of the second display area A2. The display panel 100 includes a substrate 10, a plurality of first isolation structures 20, a second isolation structure 60, a plurality of first pixel units 30 and a second pixel unit 70. The first isolation structure 20 is arranged on one side of the substrate 10 and located in the first display area A1. A light-transmitting area AA is formed between the plurality of first isolation structures 20. The first isolation structures 20 enclose at least two first isolation openings 21. The second isolation structure 60 is arranged on one side of the substrate 10 and located in the second display area A2. The second isolation structure 60 encloses at least two second isolation openings 61. The first pixel unit 30 includes at least two first sub-pixels 311. Each first sub-pixel 311 in the same first pixel unit 30 is located in each first isolation opening 21 of the same first isolation structure 20. The second pixel unit 70 includes at least two second sub-pixels 711. Each second sub-pixel 711 is correspondingly arranged in the second isolation opening 61.

[0171] In these embodiments, each first isolation structure 20 encloses at least two first isolation openings 21, and the second isolation structure 60 encloses at least two second isolation openings 61. Therefore, the pixel material can be separated into a first sub-pixel 311 and a second sub-pixel 711 by the first isolation structure 20 and the second isolation structure 60, so that the first sub-pixel 311 is located in the first isolation opening 21, and the second sub-pixel 711 is located in the second isolation opening 61, without using a mask to prepare the first sub-pixel 311 and the second sub-pixel 711, thereby saving costs.

Therefore, in the same first pixel unit 30, two adjacent first sub-pixels 311 can share part of the first isolation structure 20, thereby reducing the width of the first isolation structure 20 between the two adjacent first sub-pixels 311, reducing the coverage area of ​​the first isolation structure 20, and improving the transmittance of the first display area A1.

[0172] In some embodiments, the area of ​​the orthographic projection of the first isolation opening 21 on the substrate 10 is less than or equal to the area of ​​the orthographic projection of at least part of the second isolation opening 61 on the substrate 10, which can reduce the opening area of ​​the first isolation opening 21, so that the area of ​​the orthographic projection of the first sub-pixel 311 located in the first isolation opening 21 on the substrate 10 is smaller than the area of ​​the orthographic projection of the second sub-pixel 711 located in the second isolation opening 61 on the substrate 10, which can reduce the space occupied by the first sub-pixel 311 in the first display area A1 and further improve the transmittance of the first display area A1.

[0173] Preferably, the smallest area of ​​the orthographic projections of the second isolation openings 61 on the substrate 10 is greater than or equal to the orthographic projection area of ​​the first isolation openings 21 on the substrate, so as to further reduce the opening area of ​​the first isolation openings 21 .

[0174] Preferably, the area of ​​the orthographic projection of the first sub-pixel 311 on the substrate 10 is less than or equal to the area of ​​the orthographic projection of any second sub-pixel 711 on the substrate 10, thereby reducing the space occupied by the first sub-pixel 311 in the first display area A1 and improving the transmittance of the first display area A1.

[0175] Preferably, the shape of the orthographic projection of the second isolation opening 61 on the substrate 10 is rectangular. Compared with setting the shape of the orthographic projection of the second isolation opening 61 on the substrate 10 to be circular, the opening area of ​​the second isolation opening 61 can be increased, thereby increasing the pixel density of the second sub-pixel 711 located in the second isolation opening 61, and improving the luminous effect of the display panel 100.

[0176] Please continue reading Figure 6 Preferably, in the same first isolation structure 20 , at least two first isolation openings 21 are adjacently arranged, and the two first isolation openings 21 share part of the first isolation structure 20 , so as to reduce the coverage area of ​​the first isolation structure 20 and improve the light transmittance of the display panel 100 .

[0177] Preferably, each first isolation structure 20 encloses and forms three first isolation openings 21, so that any two first isolation openings 21 in the same first isolation structure 20 are arranged adjacent to each other, that is, any two first isolation openings 21 in the same first isolation structure 20 share part of the first isolation structure 20, thereby reducing the coverage area of ​​the first isolation structure 20. Each first pixel unit 30 includes three first sub-pixels 311, and the three first sub-pixels 311 are arranged one-to-one in the three first isolation openings 21, so that the first sub-pixels 311 in each first pixel unit 30 can be isolated by the first isolation structure 20.

[0178] Preferably, the distance between two adjacent first pixel units 30 is greater than the distance between any two adjacent first sub-pixels 311 in the first pixel unit 30 .

[0179] Specifically, multiple first pixel units 30 are arranged in one-to-one correspondence with multiple first isolation structures 20. Therefore, the distance between two adjacent first pixel units 30 is greater than the distance between any two adjacent first sub-pixels 311 in the first pixel unit 30, which can increase the gap between two adjacent first isolation structures 20, thereby improving the light transmittance effect of the display panel 100.

[0180] In some embodiments, the edge profile of the positive projection of the first isolation opening 21 on the substrate 10 is at least partially arc-shaped. Therefore, when the opening area of ​​the first isolation opening 21 is constant, the circumference of the first isolation opening 21 can be reduced, thereby further reducing the coverage area of ​​the first isolation structure 20.

[0181] Please continue reading Figure 6 Preferably, the orthographic projection of the first isolation opening on the substrate 10 is circular, so as to further reduce the perimeter of the first isolation opening 21 when the opening area is the same.

[0182] Preferably, the orthographic projection areas of the first isolation openings 21 on the substrate 10 are the same, so that the areas of the first sub-pixels 311 in the first isolation openings 21 are the same, thereby enabling the display panel 100 to emit light uniformly.

[0183] Preferably, the orthographic projection of the first sub-pixel 311 on the substrate 10 is circular in shape, so as to reduce the perimeter of the first sub-pixel 311 while keeping the same area, thereby reducing the coverage area of ​​the first sub-pixel 311 and improving the light transmittance of the display panel 100 .

[0184] Preferably, each first isolation structure 20 encloses three first isolation openings 21, and at least two first sub-pixels 311 include a first red sub-pixel 311a, a first green sub-pixel 311b and a first blue sub-pixel 311c; the first red sub-pixel 311a, the first green sub-pixel 311b and the first blue sub-pixel 311c are respectively located in the corresponding first isolation openings 21, thereby realizing color display of the display panel 100.

[0185] Preferably, at least two first sub-pixels 311 include a first red sub-pixel 311a, a first green sub-pixel 311b and a first blue sub-pixel 311c; in the same first pixel unit 30, the number of first red sub-pixels 311a, first green sub-pixels 311b and first blue sub-pixels 311c is the same, so that the first sub-pixels 311 of each color in the first pixel unit 30 are distributed as evenly as possible, so that the display panel 100 emits light evenly.
