Abstract
Description
[0001] This application is a divisional application. The original application has the application number 202511468767.1 and the original application date is October 15, 2025. The entire contents of the original application are incorporated herein by reference. Technical Field
[0002] This application relates to the field of display technology, and more particularly to a display panel. Background Technology
[0003] Organic light-emitting diode (OLED) display technology has become a research hotspot in the field of optoelectronic display technology due to its advantages such as self-illumination, wide viewing angle, high contrast, low power consumption, extremely fast response speed, ultra-lightweight and thin design, flexible display, rollable screen, strong temperature adaptability, and simple manufacturing process. The method of fabricating corresponding devices using inkjet printing technology has attracted much attention due to its high material utilization rate.
[0004] When manufacturing display devices using inkjet printing technology, to ensure uniform film formation in the display area and uniform brightness of the light-emitting devices, in addition to printing the light-emitting material in the display area, virtual pixels are generally printed around the display area using the same material to ensure uniform film formation. When the four corners of the display panel are rounded, the virtual pixel openings at the corners need to be set to arc shapes to match the rounded corners. However, since inkjet printers print at right angles in both the display and non-display areas, printing at rounded corners is more difficult, and ink is easily printed outside the virtual pixel openings. If ink overflows into the display area, it will cause color mixing problems, leading to a decrease in the yield of the display panel.
[0005] Therefore, it is necessary to provide a display panel to improve this deficiency. Summary of the Invention

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0030] Embodiments of this application provide a display panel having a display area and a non-display area located around the display area. The non-display area includes multiple side areas and multiple corner areas, each corner area being connected between adjacent side areas. The display panel includes a pixel definition layer, which includes multiple pixel openings located in the display area and multiple virtual pixel openings located in the non-display area. The multiple virtual pixel openings include at least one first virtual pixel opening and multiple second virtual pixel openings. The area of the first virtual pixel opening is larger than the area of the second virtual pixel openings. The first virtual pixel opening is located in the area of the corner area near the adjacent side area, and the first virtual pixel opening is partially curved. The area of the corner area away from the adjacent side area is provided with multiple second virtual pixel openings.
[0031] In the embodiments of this application, by forming the first virtual pixel opening only in the area of the corner region near the adjacent side area, and setting only a plurality of smaller second virtual pixel openings in the area of the corner region far from the adjacent side area, the first virtual pixel opening does not need to adapt to the arc contour of the corner region. This can reduce the difficulty of inkjet printing, avoid ink being sprayed outside the first virtual pixel opening, and thus reduce the risk of color mixing, thereby improving the production yield of the display panel.
[0032] Combination Figure 1 As shown, Figure 1 This is a top view of a display panel provided in an embodiment of this application. The display panel 100 has a display area AA and a non-display area NA located around the display area AA. The display area AA is the area used to display images, and multiple light-emitting devices and multiple pixel driving circuits for driving the light-emitting devices can be disposed within the display area AA. The non-display area NA is the area used to prevent peripheral circuits and peripheral traces from being routed. The peripheral circuits may include gate driving circuits.
[0033] like Figure 1 As shown, the non-display area NA includes a side area NA1 and a corner area NA2 that connects the adjacent side area NA1. The side area NA1 is straight, the middle part of the corner area NA2 is arc-shaped, and the part of the corner area NA2 that connects to the side area NA1 is straight.
[0034] In some embodiments, such as Figure 1 As shown, the outer contour of the display panel 100 is a rounded rectangle. The non-display area NA may include four side areas NA1 and four corner areas NA2, with each corner area NA2 connected between two adjacent side areas NA1.
[0035] In practical applications, the number of side areas NA1 and corner areas NA2 in the non-display area NA can be set according to the shape of the display panel 100. The non-display area NA can have multiple side areas NA1 and multiple corner areas NA2 at the same time.
[0036] like Figure 1 As shown, only one corner area NA2 in the non-display area NA is used as an example for explanation. The corner area NA2 includes an arc-shaped sub-area NA21 and a transition sub-area NA22 adjacent to the side area NA1 and the arc-shaped sub-area NA21. The outer contours of the transition sub-area NA22 and the adjacent side area NA1 both extend in a straight line and in the same direction. The outer contour of the arc-shaped sub-area NA21 is arc-shaped.
[0037] by Figure 1 Taking the side area NA1 on the left side of the display area AA as an example, the outer contours of the side area NA1 and the transition sub-area NA22 connected above are both straight lines and extend along the second direction Y.
[0038] Combination Figure 2 and Figure 4 As shown, Figure 2 An enlarged schematic diagram of the corner area in a first type of display panel provided for embodiments of this application. Figure 4 The first type of display panel provided for embodiments of this application is along Figure 2 The cross-sectional view along the A-A' direction shown indicates that the display panel 100 includes a pixel definition layer 1 and a light-emitting layer 2. The pixel definition layer 1 includes multiple pixel openings 11 located in the display area AA and multiple virtual pixel openings 12 located in the non-display area NA. Both the pixel openings 11 and the virtual pixel openings 12 penetrate the pixel definition layer 1 in the thickness direction of the display panel. The light-emitting layer 2 includes multiple light-emitting parts 21 and multiple virtual light-emitting parts 22. Each light-emitting part 21 is disposed in a corresponding pixel opening 11, and each virtual light-emitting part 22 is disposed in a corresponding virtual pixel opening 12.
[0039] Combination Figure 1 and Figure 2 As shown, the plurality of virtual pixel openings 12 include at least one first virtual pixel opening 121 and a plurality of second virtual pixel openings 122 located in the corner region NA2. The area of the first virtual pixel opening 121 is larger than the area of the second virtual pixel opening 122. The first virtual pixel opening 121 is located in the region of the corner region NA2 near the adjacent side region NA1. The first virtual pixel opening 121 is partially curved. The region of the corner region NA2 away from the adjacent side region NA1 is provided with a plurality of second virtual pixel openings 122.
[0040] In this embodiment, by forming the first virtual pixel opening only in the area of the corner region near the adjacent side area, and setting only a plurality of smaller second virtual pixel openings in the area of the corner region far from the adjacent side area, the first virtual pixel opening does not need to adapt to the shape of the arc-shaped sub-area of the corner region. This can reduce the difficulty of inkjet printing, avoid ink being sprayed outside the first virtual pixel opening, and thus reduce the risk of color mixing, thereby improving the production yield of the display panel.
[0041] In some embodiments, combined with Figure 1 and Figure 2 As shown, in the adjacent transition sub-region NA22, arc sub-region NA21 and side sub-region NA1, the first virtual pixel opening 121 extends from one end of the transition sub-region NA22 near the side sub-region NA1 to one end of the transition sub-region NA22 near the arc sub-region NA21, and is spaced apart from the arc sub-region NA21.
[0042] In this embodiment, by forming the first virtual pixel opening 121 only in the transition sub-region NA22 of the corner region NA2, and not setting the first virtual pixel opening 121 in the arc sub-region NA21, the first virtual pixel opening 121 does not need to adapt to the shape of the arc sub-region NA21. This can reduce the difficulty of inkjet printing and avoid ink being sprayed outside the first virtual pixel opening NA121, thus reducing the risk of color mixing and improving the production yield of the display panel.
[0043] In some embodiments, such as Figure 2 As shown, the non-display area NA includes multiple side areas NA1, which include the first side area NA11 and the second side area NA12 located on the left and right sides of the display area AA, and the third side area NA13 and the fourth side area NA14 located on the top and bottom sides of the display area AA.
[0044] In some embodiments, such as Figure 2 As shown, a transition sub-region NA22 has only one first virtual pixel opening 121. The transition sub-region NA22 located on the side of the arc-shaped sub-region NA21 near the first side region NA11 has the first virtual pixel opening 121. The transition sub-region NA22 located on the side of the arc-shaped sub-region NA21 near the third side region NA13 does not have the first virtual pixel opening 121.
[0045] It should be noted that during inkjet printing, the display panel needs to move along the first direction X. If the first virtual pixel opening 121 is provided in the transition sub-region NA22 on the side of the arc-shaped sub-region NA21 near the third side region NA13, the ink in the first virtual pixel opening 121 is prone to shaking or even overflowing during the movement of the display panel, resulting in color mixing. Therefore, in the embodiments of this application, the first virtual pixel opening 121 is only provided in the transition sub-region NA22 on the side of the arc-shaped sub-region NA21 near the first side region NA11, and the first virtual pixel opening 121 is not provided in the transition sub-region NA22 on the side of the arc-shaped sub-region NA21 near the third side region NA13.
[0046] In some embodiments, combined with Figure 2 As shown, the portion of the first virtual pixel opening 121 near the adjacent side area NA1 is straight, while the portion of the first virtual pixel opening 121 away from the adjacent side area NA1 curves and extends toward the display area AA.
[0047] In some embodiments, such as Figure 2 As shown, the first virtual pixel opening 121 includes a first opening sub-part 1211 near the side region NA1 and a second opening sub-part 1212 near the arc-shaped sub-region NA21. The first opening sub-part 1211 and the second opening sub-part 1212 are connected. The first opening sub-part 1211 and the second opening sub-part 1212 are an integral structure and belong to different parts of the first virtual pixel opening 121.
[0048] In some embodiments, such as Figure 2 As shown, the first opening sub-section 1211 is straight, and the second opening sub-section 1212 extends and curves toward the display area AA, so that the virtual pixel opening 12 of the non-display area NA can smoothly transition from the side area NA1 to the arc-shaped sub-area NA21.
[0049] In some embodiments, combined with Figure 2 and Figure 3 As shown, Figure 3 This is an enlarged schematic diagram of the opening of the first virtual pixel in the display panel provided in an embodiment of this application. The second opening sub-part 1212 includes a first sub-part 12121 and a second sub-part 12122. The first sub-part 12121 is disposed close to the first opening sub-part 1211, and the second sub-part 12122 is disposed away from the first opening sub-part 1211. The first sub-part 12121 and the second sub-part 12122 are connected.
[0050] In some embodiments, combined with Figure 2 and Figure 3As shown, the first sub-part 12121 extends towards the display area AA on both its side closest to and furthest from the display area AA, so that the entire first sub-part 12121 extends towards the display area AA, forming an arc-shaped opening. The side of the second sub-part 12122 closest to the display area AA is straight, while the side of the second sub-part 12122 furthest from the display area AA extends towards the display area AA, forming a triangular-like opening. Thus, the multiple virtual pixel openings 12 in the corner area NA2 smoothly transition from the first virtual pixel opening 121 to the second virtual pixel opening 122. Furthermore, the first virtual pixel opening 121 can be formed only in the transition sub-area NA22 of the corner area NA2, while the first virtual pixel opening 121 is not set in the arc sub-area NA21. The first virtual pixel opening 121 does not need to adapt to the shape of the arc sub-area NA21. This can reduce the difficulty of inkjet printing and avoid ink being sprayed outside the first virtual pixel opening NA121, thereby reducing the risk of color mixing and improving the production yield of the display panel.
[0051] In some embodiments, combined with Figure 2 and Figure 3 As shown, the first sub-part 12121 has a first side 12121a near the display area AA and a second side 12121b away from the display area AA. The second sub-part 12122 has a third side 12122a near the display area AA and a fourth side 12122b away from the display area AA. The third side 12122a connects the first side 12121a and the fourth side 12122b. The third side 12122a is straight and parallel to the extension direction of the side of the adjacent column of second virtual pixel openings 122. The extension direction of the side of the second virtual pixel openings 122 is the second direction Y shown in the figure. The distance between any one of the first side 12121a, the second side 12121b, and the fourth side 12122b and the adjacent column of second virtual pixel openings 122 gradually increases in the direction from the second opening sub-part 1212 to the first opening sub-part 1211. This allows the multiple virtual pixel openings 12 in the corner area NA2 to smoothly transition from the first virtual pixel opening 121 to the second virtual pixel opening 122.
[0052] In some embodiments, combined with Figure 2 and Figure 3As shown, the first side 12121a and the adjacent column of second virtual pixel openings 122 have a third distance d3 in one direction X; the second side 12121b and the adjacent column of second virtual pixel openings 122 have a fourth distance d4 in one direction X; the third side 12122a and the adjacent column of second virtual pixel openings 122 have a fifth distance d5 in one direction X; and the fourth side 12122b and the adjacent column of second virtual pixel openings 122 have a sixth distance d6 in one direction X. In the direction from the second opening sub-part 1212 to the first opening sub-part 1211, the fifth distance d5 remains unchanged, while the third distance d3, the fourth distance d4, and the sixth distance d6 gradually increase, so that the first side 12121a, the second side 12121b, and the fourth side 12122b all bend and extend toward the display area AA, thereby allowing the multiple virtual pixel openings 12 in the corner area NA2 to smoothly transition from the first virtual pixel opening 121 to the second virtual pixel opening 122.
[0053] In some embodiments, the distance between the first side 12121a and the adjacent column of second virtual pixel openings 122 is less than the distance between the second side 12121b and the adjacent column of second virtual pixel openings 122, that is, the third distance d3 is less than the fourth distance d4. This allows both the first side 12121a and the second side 12121b to bend and extend toward the display area AA, thereby allowing the multiple virtual pixel openings 12 of the corner area NA2 to smoothly transition from the first virtual pixel opening 121 to the second virtual pixel opening 122.
[0054] In some embodiments, the plurality of virtual light-emitting portions 22 include at least one first virtual light-emitting portion 221, the first virtual light-emitting portion 221 being located at the first virtual pixel opening 121, and the thickness of the portion of the first virtual light-emitting portion 221 near the adjacent side area NA1 being greater than or equal to the thickness of the portion of the first virtual light-emitting portion 221 away from the adjacent side area NA1.
[0055] In some embodiments, combined with Figure 2 and Figure 5 As shown, Figure 5 The first type of display panel provided for embodiments of this application is along Figure 2 The cross-sectional view along the B-B' direction shown indicates that the first virtual light-emitting part 221 includes a first virtual light-emitting part 2211 located in the first opening sub-part 1211 and a second virtual light-emitting part 2212 located in the second opening sub-part 1212. The first virtual light-emitting part 2211 has a first thickness h1, and the second virtual light-emitting part 2212 has a second thickness h2. The first thickness h1 is greater than or equal to the second thickness h2.
[0056] In some embodiments, combined with Figure 2 and Figure 5As shown, the thickness of the first virtual light-emitting sub-part 2211 is greater than the thickness of the second virtual light-emitting sub-part 2212. It should be noted that during inkjet printing, ink is only sprayed into the first opening sub-part 1211 of the first virtual pixel opening 121. Due to the fluidity of ink, the ink in the first opening sub-part 1211 can flow to the second opening sub-part 1212. After the ink solidifies into a film, the second virtual light-emitting sub-part 2212 of the first virtual light-emitting part 221 can be formed in the second opening sub-part 1212. When the amount of ink sprayed into the first opening sub-part 1211 is small, due to the limited fluidity of the ink, the thickness of the ink flowing to the second opening sub-part 1212 is less than the thickness of the ink in the first opening sub-part 1211, resulting in the second virtual light-emitting sub-part 2212 formed in the second opening sub-part 1212 having a thickness less than the first virtual light-emitting sub-part 2211.
[0057] In some embodiments, the thickness of the first virtual light-emitting sub-part 2211 is equal to the thickness of the second virtual light-emitting sub-part 2212. It should be noted that during inkjet printing, ink is only sprayed into the first opening sub-part 1211 of the first virtual pixel opening 121. When the amount of ink sprayed into the first opening sub-part 1211 is large, the thickness of the ink flowing to the second opening sub-part 1212 can be consistent with the thickness of the ink in the first opening sub-part 1211, so that the thickness of the second virtual light-emitting sub-part 2212 formed in the second opening sub-part 1212 is equal to the thickness of the first virtual light-emitting sub-part 2211.
[0058] In some embodiments, the pixel definition layer 1 includes a dam 13 for enclosing and forming a first virtual pixel opening 121, wherein the difference in thickness between the first virtual light-emitting sub-part 2211 and the second virtual light-emitting sub-part 2212 is less than or equal to the height of the dam 13.
[0059] In some embodiments, combined with Figure 2 and Figure 4 As shown, the first thickness h1 of the first virtual light-emitting sub-part 2211 is greater than the second thickness h2 of the second virtual light-emitting sub-part 2212. The thickness of the first virtual light-emitting sub-part 2211 is less than the height h3 of the dam 13. The thickness difference between the first virtual light-emitting sub-part 2211 and the second virtual light-emitting sub-part 2212 is less than the height of the dam 13, i.e., h1-h2<h3. This can prevent excessive ink in the first virtual pixel opening 121 from overflowing into the display area AA and causing color mixing.
[0060] In some embodiments, the first thickness h1 of the first virtual light-emitting sub-part 2211 is greater than the height h3 of the dam 13, that is, the upper surface of the first virtual light-emitting sub-part 2211 is higher than the upper surface of the dam 13. If the thickness of the second virtual light-emitting sub-part 2212 is thinner, the difference between the thickness of the first virtual light-emitting sub-part 2211 and the second virtual light-emitting sub-part 2212 can be equal to the height of the dam 13. In this way, it is also possible to prevent the ink in the first virtual pixel opening 121 from overflowing into the display area AA and causing color mixing.
[0061] In some embodiments, such as Figure 2 As shown, the plurality of virtual pixel openings 12 include a plurality of second virtual pixel openings 122 located in the arc-shaped sub-region NA21, the transition sub-region NA22, and the border sub-region NA1. The plurality of second virtual pixel openings 122 are arranged in a row extending along a first direction X in the arc-shaped sub-region NA21, the transition sub-region NA22, and the border sub-region NA1, and are arranged in a column extending along a second direction Y in the arc-shaped sub-region NA21, the transition sub-region NA22, and the border sub-region NA1. The first virtual pixel opening 121 is located on the side of the second virtual pixel openings 122 away from the display area AA, and the first direction X and the second direction Y are intersected. In the arc-shaped sub-region NA21, the plurality of second virtual pixel openings 122 located on the outermost side are arranged in a stepped manner to adapt to the arc-shaped contour of the arc-shaped sub-region NA21.
[0062] In some embodiments, such as Figure 2 As shown, n columns of second virtual pixel openings 122 are provided between the first virtual pixel opening 121 and the pixel opening 11, where n is an integer greater than or equal to 0 and less than or equal to 5. For example, when n is 0, there are no second virtual pixel openings 122 between the first virtual pixel opening 121 and the pixel opening 11; when n=3, there are 3 columns of second virtual pixel openings 122 between the first virtual pixel opening 121 and the pixel opening 11.
[0063] In some embodiments, such as Figure 2 As shown, the width of the first virtual pixel opening 121 along the first direction X is greater than the width of the second virtual pixel opening 122 along the first direction X, and the length of the first virtual pixel opening 121 along the second direction Y is greater than the length of the second virtual pixel opening 122 along the second direction Y. This allows the first virtual pixel opening 121 to hold more ink, which not only prevents ink from overflowing into the inner second virtual pixel opening 122, but also ensures that uneven areas of ink film drying fall within the non-display area NA, thereby ensuring the uniformity of the film formation of the light-emitting part 21 within the pixel opening 11 at the edge of the display area.
[0064] In some embodiments, such as Figure 2As shown, the end of the first virtual pixel opening 121 furthest from the adjacent side area NA1 does not extend beyond the first second virtual pixel opening 122 in the adjacent column. It should be noted that if the end of the first virtual pixel opening 121 near the arc-shaped sub-area NA21 extends beyond the first second virtual pixel opening 122 in the adjacent column, the first virtual pixel opening 121 will extend into the arc-shaped sub-area NA21. The shape of the first virtual pixel opening 121 would then need to adapt to the arc of the arc-shaped sub-area NA21, which would increase the difficulty of inkjet printing. This embodiment, by limiting the end of the first virtual pixel opening 121 near the arc-shaped sub-area NA21 to not extend beyond the first second virtual pixel opening 122 in the adjacent column, can reduce the difficulty of inkjet printing, prevent ink from being sprayed outside the first virtual pixel opening, thus reducing the risk of color mixing and improving the production yield of the display panel.
[0065] In some embodiments, such as Figure 2 As shown, the distance between the end of the first opening sub-part 1211 near the second opening sub-part 1212 and the first second virtual pixel opening 122 in an adjacent column in the second direction Y is defined as the first distance d1, and the center distance between two adjacent pixel openings 11 in the second direction Y is defined as the second distance d2. The ratio of the first distance d1 to the second distance d2 is greater than 1 and less than or equal to 10. For example, the ratio of the first distance d1 to the second distance d2 can be 1, 3, 5, 7, 9, or 10, etc.
[0066] It should be noted that if the ratio of the first distance d1 to the second distance d2 is too large, the first virtual pixel opening 121 will extend into the arc-shaped sub-region NA21. The shape of the first virtual pixel opening 121 would then need to be adapted to the arc of the arc-shaped sub-region NA21, which would increase the difficulty of inkjet printing. This embodiment, by limiting the ratio of the first distance d1 to the second distance d2 to between 1 and 10, can prevent the first virtual pixel opening 121 from extending into the arc-shaped sub-region NA21, reducing the difficulty of inkjet printing and preventing ink from being sprayed outside the first virtual pixel opening. Therefore, the risk of color mixing can be reduced, thereby improving the production yield of the display panel.
[0067] In some embodiments, such as Figure 2As shown, the plurality of virtual pixel openings 12 also include at least one third virtual pixel opening 123. The third virtual pixel opening 123 is disposed in the border sub-region NA1 and is elongated rectangular in shape. In the adjacent border sub-region NA1 and corner sub-region NA2, the third virtual pixel opening 123 extends from one end of the border sub-region NA1 near one of the corner sub-regions NA2 to the other end of the border sub-region NA1 near the other corner sub-region NA2. A plurality of second virtual pixel openings 122 are located on the side of the third virtual pixel opening 123 near the display area AA. The third virtual pixel opening 123 is spaced apart from the first virtual pixel opening 121.
[0068] In this embodiment, by providing a third virtual pixel opening 123 outside the plurality of second virtual pixel openings 122 in the border sub-region NA, it can be ensured that the uneven area of ink film drying falls on the non-display area NA, thereby ensuring the uniformity of film formation of the light-emitting part 21 in the pixel opening 11 at the edge of the display area.
[0069] In some embodiments, such as Figure 3 As shown, the display panel also includes an array substrate 3 and an anode layer 4 disposed on the array substrate 3. The anode layer 4 includes a plurality of patterned first anodes 41, at least one first virtual anode 42 and a plurality of second virtual anodes 43. The first anodes 41 are disposed at the bottom of the pixel opening 11, the first virtual anodes 42 are disposed at the bottom of the first virtual pixel opening 121, and the second virtual anodes 43 are disposed at the bottom of the second virtual pixel opening 122.
[0070] Combination Figure 6 As shown, Figure 6 An enlarged schematic diagram of the corner area in a second type of display panel provided in an embodiment of this application, the structure of which is similar to... Figure 1The structure of the first type of display panel shown is roughly the same, with the difference being that: the multiple virtual pixel openings 12 include two first virtual pixel openings 121 located in the same transition sub-region NA22. The two first virtual pixel openings 121 include a first sub-virtual pixel opening 121a and a second sub-virtual pixel opening 121b. The second sub-virtual pixel opening 121b is located on the side of the first sub-virtual pixel opening 121a away from the display area AA. The outer second sub-virtual pixel opening 121b can accommodate more ink, ensuring that uneven areas of ink film drying fall within the non-display area NA, thereby guaranteeing the uniformity of the film formation of the light-emitting portion 21 within the pixel opening 11 at the edge of the display area. The inner first sub-virtual pixel opening 121a can separate the second sub-virtual pixel opening 121b from the inner second virtual pixel opening 122 and pixel opening 11, preventing ink overflow from the second sub-virtual pixel opening 121b into the second virtual pixel opening 122 and pixel opening 11. This improves the uniformity of the light-emitting layer film formation while reducing the risk of color mixing.
[0071] In some embodiments, such as Figure 6 As shown, the width of the first sub-virtual pixel opening 121a is smaller than the width of the second sub-virtual pixel opening 121b. It should be noted that the second sub-virtual pixel opening 121b is mainly used to ensure that uneven areas of ink film drying fall within the non-display area NA. The first sub-virtual pixel opening 121a is mainly used to separate the second sub-virtual pixel opening 121b from the second virtual pixel opening 122 and the pixel opening 11. Therefore, the second sub-virtual pixel opening 121b needs a larger width to accommodate more ink. This embodiment, by making the width of the first sub-virtual pixel opening 121a smaller than the width of the second sub-virtual pixel opening 121b, can improve the film uniformity of the light-emitting layer while reducing the risk of color mixing.
[0072] In some embodiments, the width of the first sub-virtual pixel opening 121a is equal to the width of the second sub-virtual pixel opening 121b.
[0073] In some embodiments, the width of the first sub-virtual pixel opening 121a is greater than or equal to 0 and less than or equal to 200 micrometers. For example, the width of the first sub-virtual pixel opening 121a can be 1 micrometer, 5 micrometers, 10 micrometers, 30 micrometers, 50 micrometers, 70 micrometers, 100 micrometers, 130 micrometers, 150 micrometers, 170 micrometers, or 200 micrometers, etc.
[0074] In some embodiments, the width of the second sub-virtual pixel opening 121b is greater than or equal to 0 and less than or equal to 200 micrometers. For example, the width of the second sub-virtual pixel opening 121b can be 1 micrometer, 5 micrometers, 10 micrometers, 30 micrometers, 50 micrometers, 70 micrometers, 100 micrometers, 130 micrometers, 150 micrometers, 170 micrometers, or 200 micrometers, etc.
[0075] In some embodiments, combined with Figure 7 As shown, Figure 7 The second type of display panel provided for embodiments of this application is along Figure 6 The cross-sectional view along the C-C' direction shown shows that the multiple virtual light-emitting parts 22 include two first virtual light-emitting parts 221. The two first virtual light-emitting parts 221 are respectively provided with a first sub-virtual pixel opening 121a and a second sub-virtual pixel opening 121b. The thickness of the first virtual light-emitting part 221 in the first sub-virtual pixel opening 121a is less than the thickness of the first virtual light-emitting part 221 in the second sub-virtual pixel opening 121b. The thickness of the first virtual light-emitting part 221 in the first sub-virtual pixel opening 121a is less than the thickness of the light-emitting part 21.
[0076] In some embodiments, the thickness of the first virtual light-emitting portion 221 in the first sub-virtual pixel opening 121a is equal to the thickness of the first virtual light-emitting portion 221 in the second sub-virtual pixel opening 121b.
[0077] In some embodiments, combined with Figure 8 As shown, Figure 8 The third type of display panel provided for embodiments of this application is along... Figure 6 The cross-sectional view along the C-C' direction shows that the second sub-virtual pixel opening 121b contains a first virtual light-emitting part 221, while the first sub-virtual pixel opening 121a does not contain a virtual light-emitting part. The first sub-virtual pixel opening 121a may only contain a common light-emitting layer (not shown in the figure), which may include a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer. It should be noted that the function of the first sub-virtual pixel opening 121a is to separate the second sub-virtual pixel opening 121b from the second virtual pixel opening 122 and the pixel opening 11. Therefore, by only containing the first virtual light-emitting part 221 in the second sub-virtual pixel opening 121b, and not containing a virtual light-emitting part in the first sub-virtual pixel opening 121a, the uniformity of the light-emitting layer can be improved while reducing the risk of color mixing.
[0078] In some embodiments, combined with Figure 1 and Figure 2As shown, the first side area NA11 and the second side area NA12 are provided with multiple columns of second virtual pixel openings 122, and the third side area NA13 and the fourth side area NA14 are provided with multiple rows of second virtual pixel openings 122. The number of rows of the second virtual pixel openings 122 in either the third side area NA13 or the fourth side area NA14 is greater than the number of columns of the second virtual pixel openings 122 in either the first side area NA11 or the second side area NA12.
[0079] In this embodiment, neither the third side region NA13 nor the fourth side region NA14 has a large first virtual pixel opening. By increasing the number of second virtual pixel openings 122 in the third side region NA13 and the fourth side region NA14, the solvent concentration evaporated in the third side region NA13 and the fourth side region NA14 during the drying film formation process can be increased, thereby improving the film formation quality of the light-emitting layer in the display area AA near the third side region NA13 and the fourth side region NA14, and ensuring the uniformity of the film thickness of the light-emitting layer in each area of the display area AA.
[0080] In some embodiments, combined with Figure 1 and Figure 2 As shown, the distance between the outermost second virtual pixel opening 122 of either the first side area NA11 or the second side area NA12, which is furthest from the display area AA, and the distance between the outermost second virtual pixel opening 122 and the adjacent row of pixel openings 11 is less than the distance between the outermost second virtual pixel opening 122 of either the third side area NA13 or the fourth side area NA14, which is furthest from the display area AA, and the adjacent row of pixel openings 11. In this way, while ensuring that the width of each side area is consistent, the first side area NA11 and the second side area NA12 can reserve enough width to place the first virtual pixel opening 121, thereby reducing the difficulty of inkjet printing and improving the production yield of the display panel.
[0081] In some embodiments, combined with Figure 1 and Figure 2As shown, in either the first side area NA11 or the second side area NA12, the outermost second virtual pixel opening 122, away from the display area AA, has a seventh distance d7 in the first direction X with an adjacent row of pixel openings 11. This distance is less than or equal to an eighth distance d8 in the second direction Y with an adjacent row of pixel openings 11 on the side of the outermost second virtual pixel opening 122 away from the display area AA in either the third side area NA13 or the fourth side area NA14. The ratio of the eighth distance d8 to the seventh distance d7 is greater than or equal to 1 and less than or equal to 16. For example, the ratio of the eighth distance d8 to the seventh distance d7 can be 1, 3, 5, 7, 9, 10, 12, 14, or 16, etc. Based on the display panel provided in the above embodiments of this application, embodiments of this application also provide a display device. Please refer to [link to relevant documentation]. Figure 9 , Figure 9 This is a schematic diagram of a display device provided in an embodiment of this application. The display device 1000 includes a display panel 100 and a housing 200, with the display panel 100 disposed on the housing 200. The display panel 100 can be any of the display panels provided in the above embodiments. The display device provided in the embodiments of this application can achieve the same technical effects as the display panels provided in any of the above embodiments, and will not be described in detail here.
[0082] The beneficial effects of the embodiments of this application are as follows: This application provides a display panel including a pixel definition layer. The pixel definition layer includes a plurality of pixel openings located in the display area and a plurality of virtual pixel openings located in the non-display area. The plurality of virtual pixel openings include at least one first virtual pixel opening and a plurality of second virtual pixel openings. By forming the first virtual pixel opening only in the area of the corner area near the adjacent side area, and only setting a plurality of smaller second virtual pixel openings in the area of the corner area away from the adjacent side area, the first virtual pixel opening does not need to adapt to the arc contour of the corner area. This can reduce the difficulty of inkjet printing, avoid ink being sprayed outside the first virtual pixel opening, and thus reduce the risk of color mixing, thereby improving the production yield of the display panel.
