Description

TECHNICAL FIELD

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

[0002] Organic light emitting diodes (OLED) and flat display devices based on light emitting diode (LED) technology have been widely used in mobile phones, televisions, notebook computers, desktop computers and other consumer electronic products due to their high image quality, power saving, thin body and wide application range, and have become the mainstream in the display device field.

[0003] In the preparation process of a conventional display panel, a fine metal mask (FMM) is usually used to realize the patterning of light emitting pixels. The FMM technology is mature and has rich mass production experience. However, the FMM technology also has the problems of limited precision, high development cost and long development cycle. The fine metal mask-free technology eliminates the limitations of the conventional OLED process on the size, resolution and other performance of the display screen, and has the advantages of high performance, full size and agile delivery.

[0067] This application provides a display panel, a display device, and a method for manufacturing a display panel. The following description, in conjunction with the accompanying drawings, will illustrate various embodiments of the display panel, the display device, and the method for manufacturing a display panel.

[0068] This application provides a display panel, which may be an organic light-emitting diode (OLED) display panel.

[0069] Please refer to the following: Figures 1 to 5 , Figure 1 This is a partial top view of a display panel provided in an embodiment of this application; Figure 2 This is a partial cross-sectional view of a display panel provided in an embodiment of this application;

[0070] Figure 3This is a partial cross-sectional view of the display panel in another embodiment; Figure 4 This is a partial cross-sectional view of the display panel in yet another embodiment; Figure 5 This is a partial top view of the display panel in another embodiment.

[0071] like Figures 1 to 5 As shown, a first aspect embodiment of this application provides a display panel 10, which includes: a substrate 100; an isolation structure 200 located on one side of the substrate 100, the isolation structure 200 enclosing and forming a plurality of isolation openings 240 and a plurality of light-transmitting openings 250; and a light-emitting layer 300 located on one side of the substrate 100, the light-emitting layer 300 including a plurality of light-emitting units 310 at least partially located within the isolation openings 240, and the at least partially light-transmitting openings 250 in the orthographic projection of the substrate 100 being located between the orthographic projections of adjacent light-emitting units 310 of the same color in the substrate 100.

[0072] According to an embodiment of this application, the display panel 10 includes a substrate 100, an isolation structure 200, and a light-emitting layer 300. When the light-emitting layer 300 is fabricated, a large drop occurs at the edge of the isolation structure 200, making it difficult to connect and causing breakage. The breakage of the light-emitting layer 300 forms mutually disconnected light-emitting units 310 located within the isolation opening 240. This eliminates the need for a precision mask, reducing the development and use of precision masks and lowering manufacturing costs. The isolation structure 200 encloses and forms a light-transmitting opening 250 to improve the transmittance of the display panel 10. At least a portion of the light-transmitting opening 250 is disposed between adjacent light-emitting units 310 of the same color, making the arrangement of the isolation structure 200 and the light-transmitting opening 250 between light-emitting units 310 of the same color similar. This improves the uniformity of the arrangement of the light-transmitting opening 250 between adjacent light-emitting units 310 of the same color, reduces defects such as display mura in the display panel 10, improves the display effect of the display panel 10, and thus enhances the performance of the OLED display product.

[0073] There are many other ways to arrange the substrate 100. For example, the substrate 100 may include a substrate and an array substrate disposed on the substrate. Alternatively, the substrate 100 may be the substrate itself. Or the substrate 100 may include a buffer layer and a support plate on the side facing away from the substrate.

[0074] The composition and preparation of the isolation structure 200 are detailed in patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 099419, PCT / CN2024 / 099072, and C.

The orthographic projection of the first light-transmitting opening 260 on the substrate 100 is located between the orthographic projections of the adjacent first light-emitting units 320 on the substrate 100.

[0076] In these optional embodiments, the first light-transmitting opening 260 is disposed between adjacent first light-emitting units 320, such that the isolation structure 200 between adjacent first light-emitting units 320 and the light-transmitting opening 250 are disposed in a similar manner, thereby improving the uniformity of the arrangement of the first light-transmitting opening 260 between adjacent first light-emitting units 320 and improving defects such as display mura on the display panel 10.

[0077] Optionally, each of the first light-transmitting openings 260 has the same size, and the area, side length, and shape of the first light-transmitting openings 260 are all the same, which further improves the uniformity of the arrangement of the first light-transmitting openings 260. In the process of manufacturing or under some uncontrollable conditions, each of the first light-transmitting openings is also equivalent to having the same size within a tolerance range of ±3μm.

[0078] like Figure 1 and Figure 3 As shown, in some optional embodiments, the light-emitting unit 310 further includes a second light-emitting unit 330 spaced apart from the first light-emitting unit 320, and the light-transmitting opening 250 includes a second light-transmitting opening 270.

[0079] In these optional embodiments, the second light-transmitting opening 270 is disposed between adjacent second light-emitting units 330, such that the isolation structure 200 between adjacent second light-emitting units 330 and the light-transmitting opening 250 are disposed in a similar manner, thereby improving the uniformity of the arrangement of the second light-transmitting opening 270 between adjacent second light-emitting units 330 and improving defects such as display mura on the display panel 10.

[0082] In these optional embodiments, the third light-transmitting opening 280 is disposed between adjacent third light-emitting units 340, such that the isolation structure 200 between adjacent third light-emitting units 340 and the light-transmitting opening 250 are disposed in a similar manner, thereby improving the uniformity of the arrangement of the third light-transmitting opening 280 between adjacent third light-emitting units 340 and improving defects such as display mura on the display panel 10.

[0083] Optionally, each of the third light-transmitting openings 280 has the same size (±5μm), and the area, side length, and shape of the third light-transmitting openings 280 are the same, further improving the uniformity of the arrangement of the second light-transmitting openings 270.

[0085] Optionally, the light-transmitting openings 250 are uniformly distributed in the first direction X, and / or, the light-transmitting openings 250 are uniformly distributed in the second direction Y, wherein the first direction X and the second direction Y intersect. Uniform distribution of the light-transmitting openings 250 in the first direction X means that the light-transmitting openings 250 are evenly spaced in the first direction X, and uniform distribution of the light-transmitting openings 250 in the second direction Y means that the light-transmitting openings 250 are evenly spaced in the second direction Y, further improving the uniformity of the arrangement of the light-transmitting openings 250.

The first distance D1 corresponding to at least a portion of the light-transmitting opening 250 located between adjacent light-emitting units 310 of the same color is equal or the difference between them is less than or equal to 1.5 μm.

[0088] In these optional embodiments, the distances between the light-transmitting opening 250 and the orthogonal projection of the light-emitting unit 310 on the first direction X side of the substrate 100 are equal, thereby improving the uniformity of the arrangement of the light-transmitting opening 250 in the first direction X.

The third distance D3 corresponding to at least some of the light-transmitting openings 250 located between adjacent light-emitting units 310 of the same color is equal or the difference between them is less than or equal to 1.5 μm.

[0092] In these optional embodiments, the distances between the light-transmitting opening 250 and the orthogonal projection of the light-emitting unit 310 on the second direction Y side of the substrate 100 are equal, thereby improving the uniformity of the arrangement of the light-transmitting opening 250 in the second direction Y. For example, the distances between the first light-transmitting opening 260 located between adjacent first light-emitting units 320 and the first light-emitting unit 320 on the second direction Y side are equal; or, the distances between the second light-transmitting opening 270 located between adjacent second light-emitting units 330 and the second light-emitting unit 330 on the second direction Y side are equal; or, the distances between the third light-transmitting opening 280 located between adjacent third light-emitting units 340 and the third light-emitting unit 340 on the second direction Y side are equal.

[0093] like Figure 6 and Figure 8 As shown, in some optional embodiments, the minimum distance between the light-transmitting opening 250 and the light-emitting unit 310 located on the other side of the light-transmitting opening 250 in the second direction Y is the fourth distance D4. The fourth distance D4 corresponding to at least some of the light-transmitting openings 250 located between adjacent light-emitting units 310 of the same color is equal or the difference between them is less than or equal to 1.5 μm.

[0094] In these optional embodiments, the distances between the orthographic projection of the light-transmitting opening 250 onto the substrate 100 and the orthographic projection of the light-emitting unit 310 on the other side of the second direction Y onto the substrate 100 are all equal, further improving the uniformity of the arrangement of the light-transmitting opening 250 in the second direction Y. For example, the distances between the first light-transmitting opening 260 located between adjacent first light-emitting units 320 and the first light-emitting unit 320 on the other side of the second direction Y are all equal; or, the distances between the second light-transmitting opening 270 located between adjacent second light-emitting units 330 and the second light-emitting unit 330 on the other side of the second direction Y are all equal; or, the distances between the third light-transmitting opening 280 located between adjacent third light-emitting units 340 and the third light-emitting unit 340 on the other side of the second direction Y are all equal.

[0095] Optionally, when a certain type of light-transmitting opening 250 (e.g., first opening 261, second opening 262, third opening 263, first light-transmitting opening 260, second light-transmitting opening 270, or third light-transmitting opening 280) located among the same color light-emitting units 310 is equidistant from adjacent light-emitting units 310 in all directions, such light-transmitting opening 250 forms a light-transmitting unit. The light-transmitting unit can be translated so that the distance between a single light-transmitting opening 250 and an adjacent light-emitting unit 310 changes, but the distance between each light-transmitting opening 250 and the corresponding light-emitting unit 310 remains equal.

[0096] like Figures 6 to 8 As shown, in some optional embodiments, the minimum distance between the light-transmitting opening 250 and the light-emitting unit 310 located on the first X side of the light-transmitting opening 250 is a first distance D1, the minimum distance between the light-transmitting opening 250 and the light-emitting unit 310 located on the other side of the light-transmitting opening 250 in the first X direction is a second distance D2, and the difference between the first distance D1 and the second distance D2 is less than or equal to 1.5 μm, and / or, the minimum distance between the light-transmitting opening 250 and the light-emitting unit 310 located on the second Y side of the light-transmitting opening 250 is a third distance D3, the minimum distance between the light-transmitting opening 250 and the light-emitting unit 310 located on the other side of the light-transmitting opening 250 in the second Y direction is a fourth distance D4, and the difference between the third distance D3 and the fourth distance D4 is less than or equal to 1.5 μm. That is, the width difference between the portions of the isolation structure 200 located on both sides of the light-transmitting opening 250 in the first direction is less than or equal to 1.5 μm, and / or the width difference between the portions of the isolation structure 200 located on both sides of the light-transmitting opening 250 in the second direction Y is less than or equal to 1.5 μm. The width of this portion of the isolation structure 200 refers to the dimension of the isolation structure 200 in the direction from the light-transmitting opening 250 to the isolation opening 240.

[0097] In these optional embodiments, the width difference of the portion of the isolation structure 200 located on both sides of the light-transmitting opening 250 is less than or equal to 1.5 μm, so as to reduce the width difference of the isolation structure 200 located on both sides of the light-transmitting opening 250, thereby reducing the distribution difference of the isolation structure 200 between the light-transmitting opening 250 and the adjacent light-emitting unit 310, improving the distribution uniformity of the isolation structure 200 and the light-transmitting opening 250, and improving defects such as display mura on the display panel 10.

[0098] In some optional embodiments, the minimum distance between the light-transmitting opening 250 and the light-emitting unit 310 located on one side of the light-transmitting opening 250 in the first direction X is a first distance D1, and the minimum distance between the light-transmitting opening 250 and the light-emitting unit 310 located on the other side of the light-transmitting opening 250 in the first direction X is a second distance D2, and the first distance D1 is equal to the second distance D2. That is, the widths of the portions of the isolation structure 200 located on both sides of the light-transmitting opening 250 in the first direction X are equal.

[0099] In these alternative embodiments, the width difference between the isolation structures 200 located on both sides of the light-transmitting opening 250 in the first direction is further reduced, further improving the uniformity of the distribution of the isolation structures 200 and the light-transmitting opening 250, and improving defects such as display mura on the display panel 10.

[0100] In some optional embodiments, the minimum distance between the light-transmitting opening 250 and the light-emitting unit 310 located on one side of the light-transmitting opening 250 in the second direction Y is a third distance D3, and the minimum distance between the light-transmitting opening 250 and the light-emitting unit 310 located on the other side of the light-transmitting opening 250 in the second direction Y is a fourth distance D4, and the third distance D3 is equal to the fourth distance D4. That is, the widths of the portions of the isolation structure 200 located on both sides of the light-transmitting opening 250 in the second direction Y are equal.

[0101] In these alternative embodiments, the width difference of the isolation structures 200 located on both sides of the light-transmitting opening 250 in the second direction Y is further reduced, further improving the uniformity of the distribution of the isolation structures 200 and the light-transmitting opening 250, and improving defects such as display mura on the display panel 10.

[0102] In some alternative embodiments, at least some of the light-transmitting openings 250 are spaced apart in the first direction X, and the distance between two adjacent light-transmitting openings 250 in the first direction X is equal.

[0103] In these optional embodiments, the multiple light-transmitting openings 250 arranged in the first direction X are equally spaced, making the distribution of the light-transmitting openings 250 in the first direction X more uniform and improving the uniformity of the distribution of the light-transmitting openings 250 in the first direction X.

[0104] In some alternative embodiments, at least some of the light-transmitting openings 250 are spaced apart in the second direction Y, and the distance between two adjacent light-transmitting openings 250 in the second direction Y is equal.

[0105] In these optional embodiments, the multiple light-transmitting openings 250 arranged in the second direction Y are equally spaced, making the light-transmitting openings 250 more uniformly distributed in the second direction Y, and improving the uniformity of the distribution of the light-transmitting openings 250 in the first direction X.

[0106] Optionally, the distance between two adjacent first light-transmitting openings 260 in the first direction X is equal, and / or the distance between two adjacent first light-transmitting openings 260 in the second direction Y is equal.

[0107] Optionally, the distance between two adjacent second light-transmitting openings 270 in the first direction X is equal, and / or the distance between two adjacent second light-transmitting openings 270 in the second direction Y is equal.

[0108] Optionally, the distance between two adjacent third light-transmitting openings 280 in the first direction X is equal, and / or the distance between two adjacent third light-transmitting openings 280 in the second direction Y is equal.

[0109] In some optional embodiments, the minimum distance between the light-transmitting opening 250 and the adjacent isolation opening 240 is 2.5 μm to 20 μm. That is, the minimum distance between the orthographic projection of the light-transmitting opening 250 onto the substrate 100 and the orthographic projection of the adjacent isolation opening 240 onto the substrate 100 is 2.5 μm to 20 μm. For example, the minimum distance between the light-transmitting opening 250 and the isolation opening 240 is 2.5 μm, 5 μm, 10 μm, or 20 μm.

[0110] In these optional embodiments, the distance between the light-transmitting opening 250 and the adjacent isolation opening 240 is greater than or equal to 2.5 μm, which can improve the problem that the process precision requirements are too high and the manufacturing difficulty is too great when the distance between the light-transmitting opening 250 and the adjacent isolation opening 240 is too small. The distance between the light-transmitting opening 250 and the adjacent isolation opening 240 is less than or equal to 20 μm, which can improve the problem that the area of ​​the isolation opening 240 is set too small and the aperture ratio of the display panel 10 is low when the distance between the light-transmitting opening 250 and the adjacent isolation opening 240 is too large.

[0111] In some alternative embodiments, the isolation structure 200 includes a first layer 210 and a second layer 220 located on the side of the first layer 210 opposite to the substrate 100, wherein the orthographic projection of the first layer 210 onto the substrate 100 is within the orthographic projection of the second layer 220 onto the substrate 100.

[0112] In these optional embodiments, the isolation structure 200 includes a first layer 210 and a second layer 220 located on the side of the first layer 210 away from the substrate 100. The first layer 210 and the second layer 220 are stacked to form the isolation structure 200. The first layer 210, which is disposed close to the substrate 100, has its orthographic projection on the substrate 100 located within the orthographic projection of the second layer 220 on the substrate 100. The area of ​​the second layer 220 is larger than the area of ​​the first layer 210. The second layer 220 covers the surface of the first layer 210 that is close to the second layer 220. At this time, the first layer 210 is recessed relative to the second layer 220 in a direction away from the isolation opening 240. When the light-emitting layer 300 is fabricated, a large drop is generated at the edge of the isolation structure 200, and the first layer 210 is recessed relative to the second layer 220. The light-emitting layer 300 is difficult to connect at the edge of the isolation structure 200, resulting in breakage. The breakage of the light-emitting layer 300 forms mutually disconnected light-emitting units 310, thereby reducing crosstalk of charge carriers in the light-emitting layer 300, improving the display effect of the display panel 10, and fabricating the light-emitting unit 310 does not require the use of a precision mask, which can reduce the development and use of precision masks and reduce the fabrication cost.

[0113] Optionally, the first layer 210 includes a conductive material, such as a non-metallic conductive material or a metallic conductive material.

[0114] In some alternative embodiments, the second layer 220 includes a conductive material or an insulating material.

[0115] In these alternative embodiments, the second layer 220 includes a conductive material, such as a non-metallic conductive material or a metallic conductive material. When the second layer 220 is a non-metallic conductive material or an insulating material, it is difficult to etch the second layer 220 during the wet etching process of the first layer 210 with an etching solution, thereby making it easier for the first layer 210 to be recessed relative to the second layer 220.

[0116] In some alternative embodiments, both the first layer 210 and the second layer 220 comprise metallic materials, and the materials of the first layer 210 and the second layer 220 are different.

[0117] In these optional embodiments, when both the first layer 210 and the second layer 220 are made of metallic materials, the first layer 210 can be wet-etched using an etching solution. By adjusting the etching solution, the etching rate of the second layer 220 can be made lower than that of the first layer 210. Because the etching rate of the first layer 210 is higher, even if the second layer 220 is etched to some extent during wet etching, the first layer 210 is etched faster, thus making the first layer 210 recessed relative to the second layer 220.

[0118] Please see Figure 9 ,Figure 9 This is a partial cross-sectional view of the display panel in another embodiment.

[0119] like Figure 9 As shown, in some optional embodiments, the isolation structure 200 further includes a third layer 230 located on the side of the first layer 210 facing the substrate 100, wherein the orthographic projection of the first layer 210 onto the substrate 100 lies within the orthographic projection of the third layer 230 onto the substrate 100.

[0120] In these optional embodiments, to obtain the recessed first layer 210, the first layer 210 has a faster etching rate than the second layer 220 and the third layer 230 during the etching process, thus forming the recessed first layer 210. Because the first layer 210 has a faster etching rate, more etching waste is generated and can easily enter other parts of the display panel 10, causing adverse effects. After the third layer 230 is formed, the first layer 210 can adhere better to the third layer 230, and the generated etching waste falls onto the third layer 230, making it easier to clean.

[0121] Optionally, the light-emitting layer 300 includes an electron injection layer (EIL), an electron transport layer (ETL), a light-emitting material layer, a hole injection layer (HIL), and a hole transport layer (HTL).

[0122] In some optional embodiments, the display panel 10 further includes: a first electrode layer 400 located on the side of the light-emitting layer 300 away from the substrate 100, the first electrode layer 400 including a first electrode 400 located in the isolation opening 240, the first electrode 400 being electrically connected to the isolation structure 200.

[0123] In these optional embodiments, the isolation structure 200 isolates the first electrode layer 400 to form mutually spaced first electrodes 400. The mutually spaced first electrodes 400 are electrically connected through the isolation structure 200 to form a full-surface electrode, ensuring the normal light emission of the light-emitting unit 310.

[0124] In some optional embodiments, the display panel 10 further includes a pixel definition layer 500 located on one side of the substrate 100, the pixel definition layer 500 enclosing a plurality of pixel openings 510, the pixel openings 510 being connected to the isolation openings 240.

[0125] In these optional embodiments, the pixel definition layer 500 encloses and forms a pixel opening 510 to house the light-emitting unit 310, thereby enabling the light-emitting unit 310 to emit light normally. Furthermore, the pixel limiting portion 510 defines the setting area of ​​each light-emitting unit 310, reducing color crosstalk between the light-emitting units 310.

[0126] like Figure 9As shown, in some optional embodiments, the light-emitting unit 310 further includes a second electrode 520 located between the substrate 100 and the pixel definition layer 500, with a portion of the second electrode 520 exposed through the pixel opening 510.

[0127] Optionally, the isolation structure 200 is disposed on the pixel definition layer 500.

[0128] In some optional embodiments, the light-emitting unit 310 further includes a light-emitting device 301 disposed on the second electrode 520 and a first electrode 400 disposed on the light-emitting device 301, wherein the first electrode 400 is electrically connected to the isolation structure 200.

[0129] In these alternative embodiments, one of the second electrode 520 and the first electrode 400 serves as the anode of the light-emitting unit 310, and the other serves as the cathode of the light-emitting unit 310. This application embodiment illustrates this by using the second electrode 520 as the anode of the light-emitting unit 310 and the first electrode 400 as the cathode of the light-emitting unit 310.

[0130] A second aspect of this application provides a display panel 10, which further includes: a substrate 100; an isolation structure 200 located on one side of the substrate 100, the isolation structure 200 enclosing and forming a plurality of isolation openings 240 and a plurality of light-transmitting openings 250; and a light-emitting layer 300 located on one side of the substrate 100, the light-emitting layer 300 including a plurality of light-emitting units 310 at least partially located in the isolation openings 240, and the distance between the light-transmitting openings 250 and adjacent light-emitting units 310 of the same color being equal.

[0131] According to an embodiment of this application, the display panel 10 includes a substrate 100, an isolation structure 200, and a light-emitting layer 300. When the light-emitting layer 300 is fabricated, a large drop occurs at the edge of the isolation structure 200, making it difficult to connect and causing breakage. The breakage of the light-emitting layer 300 forms mutually disconnected light-emitting units 310 located within the isolation opening 240. This eliminates the need for a precision mask, reducing the development and use of precision masks and lowering manufacturing costs. The isolation structure 200 encloses and forms a light-transmitting opening 250 to improve the transmittance of the display panel 10. At least a portion of the light-transmitting opening 250 is equidistant from adjacent light-emitting units 310 of the same color, resulting in a more uniform arrangement of the light-transmitting opening 250 and corresponding light-emitting units 310, improving the uniformity of the light-transmitting opening 250 arrangement and reducing defects such as display mura in the display panel 10.

[0132] The structural design in this embodiment can be applied to other display panels 10. The specific choice can be made according to the actual situation. This application does not impose any specific restrictions on it. As for the distances mentioned in this application as "same" or "equal", depending on the process and some uncontrollable reasons, as long as they are within the tolerance range of ±1.5μm, they are all within the inventive concept of this application.

[0133] An embodiment of the third aspect of this application also provides a display device, including the display panel 10 of any of the first and second aspect embodiments described above. Since the display device provided in the third aspect embodiment includes the display panel 10 of any of the first and second aspect embodiments described above, the display device provided in the third aspect embodiment has the beneficial effects of the display panel 10 of any of the first and second aspect embodiments described above, which will not be elaborated further here.

[0134] The display devices in this application include, but are not limited to, mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, control consoles, and other devices with display functions.

[0135] Please see Figure 10 , Figure 10 This is a flowchart of a method for manufacturing a display panel provided in an embodiment of this application.

[0136] like Figure 10 As shown, an embodiment of the fourth aspect of this application provides a method for manufacturing a display panel 10, the method comprising:

[0137] Step S01: An isolation structure is fabricated on the substrate, and the isolation structure encloses and forms multiple isolation openings and multiple light-transmitting openings;

[0138] Step S02: Prepare a light-emitting layer on a substrate. The light-emitting layer includes a plurality of light-emitting units at least partially located within an isolation opening. The at least partially transparent opening is located between adjacent light-emitting units of the same color in the orthographic projection of the substrate.

[0139] According to the fabrication method of this application embodiment, an isolation structure 200 is fabricated on the substrate 100 in step S01. The isolation structure 200 encloses a light-transmitting opening 250 to improve the transmittance of the display panel 10. A light-emitting layer 300 is fabricated on the substrate 102 in step S02. When the light-emitting layer 300 is fabricated, a large drop occurs at the edge of the isolation structure 200, making it difficult to connect, resulting in breakage. The breakage of the light-emitting layer 300 forms mutually disconnected light-emitting units 310 located within the isolation opening 240. This eliminates the need for a precision mask, reducing the development and use of precision masks and lowering fabrication costs. At least some of the light-transmitting openings 250 are disposed between adjacent light-emitting units 310 of the same color, so that the isolation structure 200 between the light-emitting units 310 of the same color and the light-transmitting openings 250 are disposed in a similar manner, thereby improving the uniformity of the arrangement of the light-transmitting openings 250 between adjacent light-emitting units 310 of the same color, improving defects such as display mura on the display panel 10, improving the display effect of the display panel 10, and thus improving the performance of the OLED display product.

[0140] The embodiments described above are not exhaustive, nor do they limit the invention to the specific embodiments described. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to effectively utilize this application and its modifications. This application is limited only by the claims and their full scope and equivalents.
