[0087] This application provides a display panel and a display device. The following description, in conjunction with the accompanying drawings, will illustrate various embodiments of the display panel and the display device.

[0088] Figure 1 This is a partial cross-sectional view of a display panel 10 provided in an embodiment of this application. The Z direction in the figure is the thickness direction of the display panel 10.

[0089] like Figure 1 As shown, an embodiment of the first aspect of this application provides a display panel 10, including: a substrate 100; an isolation structure 300 disposed on one side of the substrate 100 and enclosing a plurality of isolation openings 300a; a light-emitting device 400, at least partially located within the isolation openings 300a; and an optical structure 600 disposed on the side of the isolation structure 300 away from the substrate 100, the optical structure 600 being used to distribute the light emitted by the light-emitting device 400.

[0090] In a display panel 10 provided in this application embodiment, the display panel 10 includes a substrate 100, an isolation structure 300, a light-emitting device 400, and an optical structure 600. The isolation structure 300 is disposed on one side of the substrate 100 and encloses a plurality of isolation openings 300a. The light-emitting device 400 is at least partially located within the isolation openings 300a. The isolation structure 300 can be used to divide the sub-pixels of the display panel 10.

[0091] The optical structure 600 can be used to distribute the light emitted by the light-emitting device 400 so that the same sub-pixel has different light emission angles relative to the left and right eyes, so as to deliver the image presented by the display panel 10 to the user's left and right eyes respectively, so that the user's left and right eyes can receive different images with parallax, thereby enabling the light emission display of the display panel 10 to produce a stereoscopic visual experience, so as to realize the naked-eye 3D display of the display panel 10.

[0092] By placing the optical structure 600 on the side of the isolation structure 300 away from the substrate 100, the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by adjusting the height of the isolation structure 300, thereby better adjusting the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400, and thus better improving the naked-eye 3D display effect of the display panel 10.

[0093] Optionally, adjusting the height of the isolation structure 300 can refer to adjusting the dimension of the isolation structure 300 in the thickness direction Z of the display panel 10.

[0094] Optionally, the orthographic projection of the optical structure 600 on the substrate 100 may at least partially overlap with the orthographic projection of the light-emitting device 400 on the substrate 100, so that the optical structure 600 can block the light emitted by the light-emitting device 400 to a certain extent to better change the light emission angle of the sub-pixel, thereby enabling the optical structure 600 to better distribute the light emitted by the light-emitting device 400.

[0095] Optionally, the optical structure 600 may extend at least partially to the isolation opening 300a. For example, the optical structure 600 may extend at least partially into the isolation opening 300a, or the optical structure 600 may extend at least partially above the isolation opening 300a, so that the optical structure 600 can block the light emitted by the light-emitting device 400 to a certain extent to better change the light emission angle of the sub-pixel.

[0096] Optionally, the optical structure 600 is disposed on the side of the isolation structure 300 away from the substrate 100. This can mean that the orthographic projection of the optical structure 600 on the substrate 100 and the orthographic projection of the isolation structure 300 on the substrate 100 are at least partially overlapped, so that the height of the isolation structure 300 can better influence the height of the optical structure 600 relative to the light-emitting device 400, so as to ensure that the optical structure 600 affects the light emission angle of the sub-pixel relative to the left and right eyes by changing its height.

[0097] In some embodiments of this application, the substrate 100 can be configured in various ways. For example, the substrate 100 may include a substrate 110 and a driving circuit 150 disposed on the substrate 110. Optionally, the substrate 100 includes a first insulating layer 120, a second insulating layer 130, and a third insulating layer 140 stacked together. Exemplarily, the driving circuit 150 may include a transistor 151, a storage capacitor 152, and driving signal lines for connecting various devices. The transistor 151 includes a semiconductor, a gate 151a, and a source / drain electrode 151b. The storage capacitor 152 includes a first electrode 152a and a second electrode 152b. As an example, the gate 151a and the first electrode 152a may be located on the side of the first insulating layer 120 facing the substrate 110, the second electrode 152b may be located between the first insulating layer 120 and the second insulating layer 130, and the source / drain electrode 151b may be located between the second insulating layer 130 and the third insulating layer 140.

[0098] In some alternative embodiments, in the direction away from the substrate 100, the light-emitting device 400 includes a first electrode 410, a light-emitting layer 420 and a second electrode 430 stacked sequentially.

[0099] Optionally, the light-emitting layer 420 may include a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting structure, an electron injection layer (EIL), and an electron transport layer (ETL).

[0100] In these optional embodiments, the first electrode 410 and the second electrode 430 can serve as pixel electrodes of the display panel 10. One of the first electrode 410 and the second electrode 430 can serve as an anode, and the other can serve as a cathode to drive the light-emitting layer 420 to emit light. This application embodiment illustrates this by using the first electrode 410 as the anode of the display panel 10 and the second electrode 430 as the cathode of the display panel 10.

[0101] In some optional embodiments, the display panel 10 may further include a pixel definition layer 200 disposed on one side of the substrate 100. The pixel definition layer 200 may include a pixel limiting portion 210 and a pixel opening 220 formed by the pixel limiting portion 210. The pixel opening 220 may communicate with the isolation structure 300. The light-emitting device 400 may also be located at least partially within the pixel opening 220. The pixel definition layer 200 may also be used to divide the sub-pixels of the display panel 10.

[0102] In some embodiments of this application, the relative position between the pixel limiting portion 210 and the isolation structure 300 can be configured in various ways, for example, such as Figure 1 As shown, the isolation structure 300 can be disposed on the side of the pixel limiting portion 210 facing away from the substrate 100, that is, the isolation structure 300 can be directly disposed on the pixel limiting portion 210. Alternatively, the pixel limiting portion 210 can have a receiving groove, and at least a portion of the isolation structure 300 can be located in the receiving groove, so that the isolation structure 300 500 is less likely to have an excessive height relative to the substrate 100, thereby effectively reducing the thickness of the display panel 10. For ease of description, the following embodiments will be described using the example of the isolation structure 300 being disposed on the side of the pixel limiting portion 210 facing away from the substrate 100.

[0103] In some alternative embodiments, the isolation structure 300 includes a first isolation portion 310 and a second isolation portion 320 located on the side of the first isolation portion 310 away from the substrate 100, the second isolation portion 320 being disposed protruding from the first isolation portion 310 toward the isolation opening 300a.

[0104] By providing the second isolation portion 320 protruding from the first isolation portion 310 toward the isolation opening 300a, the second isolation portion 320 can block at least part of the material used to prepare the light-emitting layer 420 and the second electrode 430 when the light-emitting layer 420 and the second electrode 430 of the display panel 10 are deposited, thereby isolating the light-emitting layer 420 and the second electrode 430 between adjacent sub-pixels. This facilitates the formation of multiple spaced light-emitting layers 420 and the second electrode 430, thereby eliminating the need for a high-precision mask when depositing the light-emitting layer 420 and the second electrode 430 of the display panel 10. For example, it eliminates the need for a high-precision fine metal mask (FMM) when depositing the light-emitting layer 420 and the second electrode 430, thus significantly reducing the manufacturing cost of the display panel 10.

[0105] Optionally, the material of the isolation structure 300 may include a conductive material, and the second electrode 430 may be connected to the isolation structure 300, so that the second electrodes 430 in adjacent isolation openings 300a can be interconnected through the isolation structure 300 to form a surface electrode, so as to facilitate the control of the second electrode 430 in the display panel 10.

[0106] Optionally, the isolation structure 300 further includes a third isolation portion 330 disposed on the side of the first isolation portion 310 facing the substrate 100, the third isolation portion 330 protruding from the first isolation portion 310 toward the isolation opening 300a. The second electrode 430 can be connected to the third isolation portion 330. By making the third isolation portion 330 protrude from the first isolation portion 310 toward the isolation opening 300a, the third isolation portion 330 can have a larger size, facilitating the connection between the second electrode 430 and the third isolation portion 330, and thus improving the connection stability between the second electrode 430 and the isolation structure 300.

[0107] In the aforementioned optional embodiments, the isolation effect of the isolation structure 300 on the light-emitting layer 420 and the second electrode 430 can be adjusted by adjusting the height of the isolation structure 300, thereby enabling adjustment of the distance between the isolation structure 300, the light-emitting layer 420, and the second electrode 430. Specifically, by reasonably adjusting the height of the isolation structure 300, the light-emitting layer 420 can be spaced apart from the isolation structure 300 to reduce light emission crosstalk between adjacent sub-pixels and to allow the second electrode 430 to connect better with the isolation structure 300, thereby improving the electrical connection effect between the second electrode 430 and the isolation structure 300. Therefore, by setting the optical structure 600 on the side of the isolation structure 300 away from the substrate 100, while adjusting the height of the isolation structure 300 to adjust its isolation effect on the light-emitting layer 420 and the second electrode 430, the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400 can also be adjusted accordingly.

[0108] In some embodiments of this application, there are various types of optical structures 600 that can participate in realizing naked-eye 3D display.

[0109] like Figure 1 As shown, in some optional embodiments, the optical structure 600 includes a plurality of light-shielding structures 610. These light-shielding structures 610 can be used to block the light emitted by the light-emitting device 400, distributing the light emitted by the light-emitting device 400 to the user's left and right eyes respectively. This allows the light-shielding structure 610 to function as a grating structure, enabling the user's left and right eyes to receive different images containing parallax. Specifically, the light-shielding structure 610 can function as a parallax barrier to allow the light emitted by the display panel 10 to produce a stereoscopic visual experience.

[0110] Figure 2 This is a schematic diagram of a light-shielding structure 610 provided in an embodiment of this application. In the figure, the X direction is the first direction X, and the Y direction is the second direction Y. The first direction X and the second direction Y can intersect each other with the thickness direction Z of the display panel 10. For example, the first direction X and the second direction Y can be perpendicular to the thickness direction Z of the display panel 10.

[0111] Optional, such as Figure 2 As shown, at least part of the light-shielding structure 610 can be extended and formed along the first direction X and spaced apart in the second direction Y, so that the light-shielding structure 610 can better control the propagation path of the light emitted by the light-emitting device 400 in the second direction Y. When the distance between the user's left eye and right eye is the second direction Y, that is, when the user's left eye is located on the side of the right eye in the second direction Y, the user's left eye and right eye can receive different images with parallax in the second direction Y, thereby enabling the light-emitting display of the display panel 10 to produce a stereoscopic visual experience, so as to realize the naked-eye 3D display of the display panel 10.

[0112] Figure 3 This is a schematic diagram of a light-shielding structure 610 provided in another embodiment of this application.

[0113] Optional, such as Figure 3As shown, the multiple light-shielding structures 610 include a first light-shielding structure and a second light-shielding structure arranged in a cross pattern. The first light-shielding structure extends along the first direction X and is spaced apart along the second direction Y. The second light-shielding structure extends along the second direction Y and is spaced apart along the first direction X. This allows the light-shielding structure 610 to better control the propagation path of the light emitted by the light-emitting device 400 in the first direction X. When the distance between the user's left eye and right eye is the first direction X, that is, when the user's left eye is located on the side of the right eye in the first direction X, the user's left eye and right eye can receive different images with parallax in the first direction X. This allows the light-emitting display of the display panel 10 to produce a stereoscopic visual experience, thereby realizing the naked-eye 3D display of the display panel 10.

[0114] Optional, such as Figure 3 As shown, multiple light-shielding structures 610 form multiple arrayed light-transmitting openings. The orthographic projection of the light-transmitting openings on the substrate 100 partially overlaps with the orthographic projection of the light-emitting device 400 on the substrate 100. The orthographic projection of the light-shielding structure 610 on the substrate 100 can be mesh-like and partially blocks the light-emitting device 400. This allows the user's left and right eyes to receive different images with parallax when the distance between the user's left and right eyes is the first direction X, or when the distance between the user's left and right eyes is the second direction Y. This enables the user to experience stereoscopic vision when observing the display panel 10 from different angles, thereby improving the naked-eye 3D display effect of the display panel 10.

[0115] like Figure 1 As shown, optionally, in the first direction X or the second direction Y, the overlapping area of ​​a portion of the orthographic projection of the light-shielding structure 610 on the substrate 100 and the orthographic projection of the light-emitting device 400 on the substrate 100 may be different from the overlapping area of ​​another portion of the orthographic projection of the light-shielding structure 610 on the substrate 100 and the orthographic projection of the light-emitting device 400 on the substrate 100. This results in at least some different light-shielding structures 610 blocking light emitted by different light-emitting devices 400 to different degrees, so that the image presented by the display panel 10 is transmitted to the user's left and right eyes respectively, allowing the user's left and right eyes to receive different images containing parallax.

[0116] Optionally, the light-shielding structure 610 overlaps with the orthographic projection of the light-emitting device 400 located on the side of the light-shielding structure closer to the substrate, and the overlapping areas of adjacent light-shielding structures 610 and light-emitting devices 400 are different.

[0117] Optionally, the overlapping area of ​​the projection of the light-shielding structure 610 on the substrate 100 and the projection of the light-emitting device 400 on the substrate 100 in the viewing direction of the left and right eyes can be adjusted by adjusting the setting position of different light-shielding structures 610 relative to the light-emitting device 400. That is, since the viewing angle of the left or right eye and the light-emitting edge of a single sub-pixel is usually tilted, the higher the relative position of the light-shielding structure 610 and the light-emitting device 400 in the viewing direction, the larger the blocking angle, thereby adjusting the left and right eyes to have different images.

[0118] Optionally, the overlap area between the orthographic projection of the light-shielding structure 610 on the substrate 100 and the orthographic projection of the light-emitting device 400 on the substrate 100 can be adjusted by adjusting the width of different light-shielding structures 610.

[0119] Figure 4 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0120] like Figure 4 As shown, in some optional embodiments, the display panel 10 further includes at least one encapsulation layer 500 disposed on the side of the light-emitting device 400 away from the substrate 100, and the optical structure 600 disposed on the side of the at least one encapsulation layer 500 away from the substrate 100.

[0121] In this optional embodiment, the encapsulation layer 500 can be used to encapsulate the light-emitting device 400. By disposing the optical structure 600 on the side of at least one encapsulation layer 500 facing away from the substrate 100, the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by adjusting the thickness of the at least one encapsulation layer 500, thereby better adjusting the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400. Furthermore, when patterning processing is required for the optical structure 600, for example, when patterning the material of the light-shielding structure 610, the encapsulation layer 500 provides a certain degree of protection to the light-emitting device 400 and the isolation structure 300, making it less likely for the etching material to cause etching damage to the light-emitting device 400 and the isolation structure 300, thereby improving the structural reliability of the display panel 10.

[0122] In some optional embodiments, at least one encapsulation layer 500 includes a first encapsulation layer 510, which covers the side of the light-emitting device 400 away from the substrate 100 and extends to the side of the isolation structure 300 away from the substrate 100. The first encapsulation layer 510 includes encapsulation units 511 disposed corresponding to each isolation opening 300a.

[0123] Optionally, the encapsulation unit 511 provided for each isolation opening 300a may refer to the fact that each isolation opening 300a is provided with an encapsulation unit 511, and each encapsulation unit 511 is provided for only one isolation opening 300a.

[0124] Optionally, adjacent packaging units 511 are spaced apart.

[0125] Optionally, the material of the first type of encapsulation layer 510 may include inorganic materials.

[0126] Optionally, the first type of encapsulation layer 510 can be prepared by chemical vapor deposition (CVD).

[0127] In these optional embodiments, the encapsulation unit 511 can be used to encapsulate the light-emitting devices 400 in different isolation openings 300a in a relatively independent manner. That is, each light-emitting device 400 in isolation opening 300a has at least one corresponding encapsulation unit 511 for encapsulation. This makes it less likely to affect the encapsulation effect of adjacent encapsulation units 511 when the encapsulation of the light-emitting device 400 in isolation opening 300a by a certain encapsulation unit 511 fails, so as to better improve the encapsulation effect of the encapsulation layer 500.

[0128] In some alternative embodiments, the optical structure 600 may be disposed on the side of the packaging unit 511 opposite to the substrate 100.

[0129] Optionally, at least a portion of the optical structure 600 may be disposed in contact with the side of the packaging unit 511 facing away from the substrate 100.

[0130] Optionally, at least a partial light-shielding structure 610 may be disposed on the side of the packaging unit 511 facing away from the substrate 100.

[0131] In these optional embodiments, by disposing at least a portion of the optical structure 600 on the side of the encapsulation unit 511 facing away from the substrate 100, the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by adjusting the thickness of the encapsulation unit 511, thereby better regulating the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400. For example, the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by adjusting the thickness of the encapsulation unit 511, thereby better regulating the blocking effect of the light-shielding structure 610 on the light emitted by the light-emitting device 400. This makes it less likely for the light-shielding structure 610 to have a significant blocking effect on the light emitted by the light-emitting device 400, and also reduces the risk of unwanted light leaking from the light-shielding structure 610. This better controls the propagation path of the light emitted by the light-emitting device 400 in the second direction Y, realizing the naked-eye 3D display of the display panel 10.

[0132] In some alternative embodiments, the packaging unit 511 includes a first packaging portion 511a located on the side of the isolation structure 300 away from the substrate 100, and at least a portion of the optical structure 600 is disposed on the side of the first packaging portion 511a away from the substrate 100.

[0133] Optionally, at least a partial light-shielding structure 610 may be disposed on the side of the first encapsulation portion 511a away from the substrate 100.

[0134] In these optional embodiments, by placing the optical structure 600 on the side of the first encapsulation portion 511a above the isolation structure 300 away from the substrate 100, a film material of the isolation structure 300 and the first encapsulation portion 511a can be stacked below the optical structure 600. This allows for better adjustment of the light distribution effect of the optical structure 600 on the light-emitting device 400 by simultaneously adjusting the height of the isolation structure 300 and the thickness of the first encapsulation portion 511a. Furthermore, when the optical structure 600 includes a light-shielding structure 610, by placing the light-shielding structure 610 on the first encapsulation portion 511a, the light-shielding structure 610 is less likely to significantly obstruct the light emitted by the light-emitting device 400, thereby improving the operational reliability of the light-shielding structure 610.

[0135] Optionally, the first encapsulation portion 511a and the isolation structure 300 are spaced apart, so that the distance between the first encapsulation portion 511a and the isolation structure 300 can be adjusted to adjust the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400.

[0136] Optionally, the packaging unit 511 further includes a second packaging part 511b and a third packaging part 511c. The second packaging part 511b covers the side of the isolation structure 300 facing the isolation opening 300a and is connected to the first packaging part 511a. The third packaging part 511c covers the side of the light-emitting device 400 away from the substrate 100 and is connected to the second packaging part 511b.

[0137] The third encapsulation part 511c is mainly used to encapsulate the light-emitting device 400. The second encapsulation part 511b connected to the third encapsulation part 511c and the first encapsulation part 511a connected to the second encapsulation part 511b can effectively extend the encapsulation path of the encapsulation unit 511 to the light-emitting device 400, so that external impurities are not easy to invade the light-emitting device 400 through the edge of the encapsulation unit 511, thereby improving the encapsulation effect of the display panel 10.

[0138] Figure 5 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0139] like Figure 5As shown, in some optional embodiments, the display panel 10 further includes a first support structure S1 that is at least partially located in the isolation opening 300a and covers the side of the encapsulation unit 511 away from the substrate 100, and at least a portion of the optical structure 600 is disposed on the side of the first support structure S1 away from the substrate 100.

[0140] Optionally, at least a partial light-shielding structure 610 may be disposed on the side of the first support structure S1 away from the substrate 100.

[0141] Optionally, the distance between the surface of the first support structure S1 facing away from the substrate 100 and the substrate 100 may be less than or equal to the distance between the surface of the first package portion 511a facing away from the substrate 100 and the substrate 100. For example, the side of the first support structure S1 facing away from the substrate 100 may be lower than the side of the first package portion 511a facing away from the substrate 100 (not shown in the figure), or the side of the first support structure S1 facing away from the substrate 100 may be flush with the side of the first package portion 511a facing away from the substrate 100.

[0142] When the side of the first support structure S1 facing away from the substrate 100 is lower than the side of the first encapsulation portion 511a facing away from the substrate 100, the optical structure 600 disposed on the side of the first support structure S1 facing away from the substrate 100 may be partially located within the isolation opening 300a.

[0143] Alternatively, the distance between the surface of the first support structure S1 facing away from the substrate 100 and the substrate 100 may be greater than or equal to the distance between the surface of the first encapsulation portion 511a facing away from the substrate 100 and the substrate 100. Optionally, the first support structure S1 may also fill the gap between the first encapsulation portion 511a and the isolation structure 300.

[0144] Optional, such as Figure 5 As shown, when the distance between the surface of the first support structure S1 facing away from the substrate 100 and the substrate 100 is equal to the distance between the surface of the first encapsulation part 511a facing away from the substrate 100 and the substrate 100, a portion of the optical structure 600 can be disposed on the side of the first support structure S1 facing away from the substrate 100, and another portion of the optical structure 600 can be disposed on the side of the first encapsulation part 511a facing away from the substrate 100.

[0145] Optionally, when the distance between the surface of the first support structure S1 facing away from the substrate 100 and the substrate 100 is greater than the distance between the surface of the first encapsulation part 511a facing away from the substrate 100 and the substrate 100, the optical structure 600 can be disposed on the side of the first support structure S1 facing away from the substrate 100, so that the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by adjusting the thickness of the first support structure S1, so as to better adjust the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400.

[0146] Optionally, the first support structure S1 may have good light transmittance to reduce the obstruction of light emitted by the light-emitting device 400 by the first support structure S1 and improve the light emission display effect of the display panel 10.

[0147] In these optional embodiments, when the thickness of the first type of encapsulation layer 510 is relatively thin and it is easy to be uneven within the isolation opening 300a, that is, when the first type of encapsulation layer 510 located within the isolation opening 300a has a large height difference, the first support structure S1 disposed on the side of the encapsulation unit 511 away from the substrate 100 can play a better flattening role, that is, the surface of the side of the first support structure S1 away from the substrate 100 can be relatively flat. By disposing at least a portion of the optical structure 600 on the side of the first support structure S1 away from the substrate 100, the adjacent optical structure 600 and the optical structure 600 itself are less likely to have a large height difference, which facilitates the arrangement of the optical structure 600.

[0148] Optionally, the material of the first support structure S1 includes an organic material, which allows the material of the first support structure S1 to have good flowability during fabrication, and allows the surface of the first support structure S1 facing away from the substrate 100 to have good flatness, so as to facilitate the arrangement of the optical structure 600. For example, the first support structure S1 may include one of photoresist, transparent optical adhesive, and leveling organic adhesive.

[0149] Optionally, at least a portion of the first support structure S1 can be reused as a color filter (CF). For example, the first support structure S1 can be reused as a color filter that allows red light to pass through, a color filter that allows green light to pass through, or a color filter that allows blue light to pass through. The color of the color filter can be the same as the emission color of the light-emitting device 400 located on the side of the first support structure S1 closest to the substrate 100, so that the light emitted by the light-emitting device 400 can pass through the color filter and be emitted outward.

[0150] By reusing at least a portion of the first support structure S1 as a color resist, the color resist of the display panel 10 can be arranged within the isolation opening 300a to reduce the thickness of the display panel 10, while also providing better support for the optical structure 600. Furthermore, the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by regulating the thickness of the color resist, thereby better regulating the distribution of light emitted by the light-emitting device 400 from the optical structure 600.

[0151] When the optical structure 600 includes a light-shielding structure 610, the light-shielding structure 610 can also effectively reduce the reflectivity of the display panel 10, making it less prone to reflection when the display panel 10 is displaying light.

[0152] Figure 6 This is a schematic diagram of a lens structure 620 provided in another embodiment of this application. Figure 7 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application. Figure 8 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0153] like Figures 6 to 8 As shown, in some optional embodiments, the optical structure 600 may include a lens structure 620, which can be used to refract and split the light emitted by the light-emitting device 400 so as to deliver the light emitted by the light-emitting device 400 to the user's left eye and right eye at different light emission angles, so that the user's left eye and right eye can receive different images containing parallax.

[0154] Optionally, the lens structure 620 includes multiple lens units 621. The lens units 621 extend along the first direction X and are arranged side by side in the second direction Y. This allows the lens units to better control the propagation path of the light emitted by the light-emitting device 400 in the second direction Y through refraction. When the distance between the user's left and right eyes is the second direction Y, that is, when the user's left eye is located on the side of the right eye in the second direction Y, the user's left and right eyes can receive different images with parallax in the second direction Y. This allows the light-emitting display of the display panel 10 to produce a stereoscopic visual experience, thereby realizing naked-eye 3D of the display panel 10.

[0155] In some embodiments of this application, the refraction and beam splitting of the lens unit 621 can be achieved in various ways. The refraction and beam splitting of the lens unit 621 can be adjusted by regulating the surface topography of the side of the lens unit 621 facing away from the substrate 100. For example, as... Figure 7 As shown, the lens unit 621 may include a prism. For example, as Figure 8 As shown, at least a portion of the lens unit 621 has a curved surface on the side facing away from the substrate 100.

[0156] In the second direction Y, the orthogonal projection of the lens unit 621 onto the substrate 100 covers the orthogonal projection of at least one light-emitting device 400 onto the substrate 100.

[0157] Optional, such as Figure 7 and Figure 8 As shown, the lens structure 620 can be disposed on the side of the first support structure S1 away from the substrate 100. The relatively flat surface of the side of the first support structure S1 away from the substrate 100 facilitates the arrangement of the lens structure 620.

[0158] Optionally, at least a portion of the first support structure S1 may also be filled between adjacent packaging units 511 to further facilitate the step arrangement of the optical structure 600.

[0159] Figure 9 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application. Figure 10 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0160] like Figure 9 and Figure 10 As shown, in some optional embodiments, at least one encapsulation layer 500 may include a second encapsulation layer 520 disposed on the side of the first encapsulation layer 510 away from the substrate 100. The second encapsulation layer 520 may also encapsulate the display panel 10 to further improve the encapsulation effect of the display panel 10.

[0161] Optionally, the material of the second type of encapsulation layer 520 includes an organic material, which allows the material of the second type of encapsulation layer 520 to have good flowability during its fabrication, and allows the surface of the second type of encapsulation layer 520 facing away from the substrate 100 to have good flatness, so as to facilitate the subsequent arrangement of devices.

[0162] Optionally, the second encapsulation layer 520 can be prepared using inkjet printing (IJP) technology.

[0163] In some embodiments of this application, there are various ways to set the relative positional relationship between the optical structure 600 and the second type of encapsulation layer 520.

[0164] In some alternative embodiments, such as Figure 9 and Figure 10 As shown, at least a portion of the optical structure 600 may be disposed between the first type of encapsulation layer 510 and the second type of encapsulation layer 520.

[0165] Optionally, at least a portion of the light-shielding structure 610 may be disposed between the first type of encapsulation layer 510 and the second type of encapsulation layer 520. Optionally, at least a portion of the lens structure 620 may be disposed between the first type of encapsulation layer 510 and the second type of encapsulation layer 520.

[0166] In some optional embodiments, the second type of encapsulation layer 520 includes a support portion 521 located at least partially within the isolation opening 300a and covering the side of the encapsulation unit 511 opposite to the substrate 100, and a main body portion 522 located on the side of the support portion 521 opposite to the substrate 100. At least a portion of the optical structure 600 is disposed between the support portion 521 and the main body portion 522. The second type of encapsulation layer 520 also fills the gap between the first encapsulation portion 511a and the isolation structure 300.

[0167] Optionally, at least a partial light-shielding structure 610 may be disposed between the support portion 521 and the main body portion 522. Optionally, at least a partial lens structure 620 may be disposed between the support portion 521 and the main body portion 522.

[0168] Optionally, the thickness of the support portion 521 may be greater than or equal to the distance between the surface of the first encapsulation portion 511a facing away from the substrate 100 and the substrate 100.

[0169] Optional, such as Figure 9 and Figure 10 As shown, when the thickness of the support portion 521 is equal to the distance between the surface of the first encapsulation portion 511a away from the substrate 100 and the substrate 100, a portion of the optical structure 600 can be disposed between the support portion 521 and the main body portion 522, and another portion of the optical structure 600 can be disposed on the side of the first encapsulation portion 511a away from the substrate 100.

[0170] Optionally, when the thickness of the main body 522 is greater than the distance between the surface of the first encapsulation part 511a facing away from the substrate 100 and the substrate 100, the optical structure 600 can be disposed between the support part 521 and the main body 522, so that the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by adjusting the thickness of the support part 521, so as to better adjust the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400.

[0171] In these alternative embodiments, during the fabrication of the display panel 10, the support portion 521 of the second encapsulation layer 520 can be fabricated first. At this time, the surface of the support portion 521 facing away from the substrate 100 can have good flatness. Then, the optical structure 600 is fabricated above the support portion 521, which reduces the difficulty of arranging the optical structure 600. Then, the main body portion 522 of the second encapsulation layer 520 is fabricated on the optical structure 600 and the support portion 521 to complete the fabrication of the second encapsulation layer 520.

[0173] In some alternative embodiments, such as Figure 11 and Figure 12 As shown, at least a portion of the optical structure 600 is disposed on the side of the second type of encapsulation layer 520 away from the substrate 100.

[0174] Optionally, at least a portion of the light-shielding structure 610 may be disposed on the side of the second encapsulation layer 520 facing away from the substrate 100. Optionally, at least a portion of the lens structure 620 may be disposed on the side of the second encapsulation layer 520 facing away from the substrate 100.

[0175] In these optional embodiments, the surface of the second encapsulation layer 520 facing away from the substrate 100 can have good flatness, which facilitates the arrangement of the optical structure 600. Furthermore, the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by adjusting the thickness of the second encapsulation layer 520, thereby better adjusting the light distribution effect of the optical structure 600 on the light-emitting device 400. In addition, by disposing at least a portion of the optical structure 600 on the side of the second encapsulation layer 520 facing away from the substrate 100, the second encapsulation layer 520 can provide better protection for the first encapsulation layer 510 during patterning processes of the optical structure 600, for example, when patterning the light-shielding structure 610, preventing excessive damage to the first encapsulation layer 510 by the etching material, thus improving the encapsulation effect of the display panel 10.

[0177] like Figure 13 and Figure 14 As shown, in some optional embodiments, at least one encapsulation layer 500 includes a third encapsulation layer 530 disposed on the side of the second encapsulation layer 520 away from the substrate 100. The third encapsulation layer 530 can also encapsulate the display panel 10 to further improve the encapsulation effect of the display panel 10.

[0184] In some alternative embodiments, such as Figure 15 and Figure 16 As shown, at least a portion of the optical structure 600 is disposed on the side of the third type of encapsulation layer 530 away from the substrate 100.

[0185] Optionally, at least a portion of the light-shielding structure 610 may be disposed on the side of the third encapsulation layer 530 facing away from the substrate 100. Optionally, at least a portion of the lens structure 620 may be disposed on the side of the third encapsulation layer 530 facing away from the substrate 100.

[0186] In these optional embodiments, by disposing at least a portion of the optical structure 600 on the side of the third encapsulation layer 530 facing away from the substrate 100, the third encapsulation layer 530 can better protect the second encapsulation layer 520 during patterning of the optical structure 600, for example, during patterning of the light-shielding structure 610, thus preventing excessive damage to the second encapsulation layer 520 by the etching material, thereby improving the encapsulation effect of the display panel 10. Furthermore, the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by adjusting the thickness of the third encapsulation layer 530, thereby better adjusting the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400.

[0187] Figure 17 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application. Figure 18 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0188] like Figure 17 and Figure 18 As shown, in some optional embodiments, the display panel 10 further includes a second support structure S2 covering the side of the third encapsulation layer 530 away from the substrate 100, and at least a portion of the optical structure 600 is disposed on the side of the second support structure S2 away from the substrate 100.

[0189] Optionally, at least a portion of the light-shielding structure 610 may be disposed on the side of the second support structure S2 opposite to the substrate 100. Optionally, at least a portion of the lens structure 620 may be disposed on the side of the second support structure S2 opposite to the substrate 100.

[0190] Optionally, the second support structure S2 may have better light transmittance to reduce the obstruction of light emitted by the light-emitting device 400 and improve the light emission display effect of the display panel 10.

[0191] Optionally, the material of the second support structure S2 includes an organic material, which allows the material of the second support structure S2 to have good flowability during fabrication, and allows the surface of the second support structure S2 facing away from the substrate 100 to have good flatness, so as to facilitate the arrangement of the optical structure 600. For example, the second support structure S2 may include one of photoresist, transparent optical adhesive, and organic leveling adhesive.

[0192] In these optional embodiments, by disposing at least a portion of the optical structure 600 on the side of the second support structure S2 away from the substrate 100, the height of the optical structure 600 relative to the light-emitting device 400 can be adjusted by adjusting the thickness of the second support structure S2, thereby better regulating the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400. Furthermore, when patterning the optical structure 600, for example, when patterning the light-shielding structure 610, the second support structure S2 can provide better protection for the third encapsulation layer 530, making it less likely for the etching material to cause excessive damage to the third encapsulation layer 530, thus improving the encapsulation effect of the display panel 10.

[0193] In some alternative embodiments, the display panel 10 also includes touch electrodes 700, at least a portion of which is reused as optical structure 600. For example, at least a portion of the touch electrodes 700 may be reused as light-shielding structure 610.

[0194] Optionally, the placement position of the touch electrode 700, which is reused as the optical structure 600, can be set with reference to the placement position of the optical structure 600 in any of the foregoing embodiments. For example, the touch electrode 700, which is reused as the optical structure 600, can be disposed on the side of the isolation structure 300 facing away from the substrate 100. For example, the touch electrode 700, which is reused as the optical structure 600, can be disposed on the side of the first encapsulation layer 510 facing away from the substrate 100. Specifically, the touch electrode 700, which is reused as the optical structure 600, can be disposed between the first encapsulation layer 510 and the second encapsulation layer 520. For example, the touch electrode 700, which is reused as the optical structure 600, can be disposed on the side of the first support structure S1 facing away from the substrate 100. For example, the touch electrode 700, which is reused as an optical structure 600, can be disposed on the side of the second type of encapsulation layer 520 facing away from the substrate 100. Specifically, the touch electrode 700, which is reused as an optical structure 600, can be disposed between the second type of encapsulation layer 520 and the third type of encapsulation layer 530. For example, the touch electrode 700, which is reused as an optical structure 600, can be disposed on the side of the third type of encapsulation layer 530 facing away from the substrate 100. For example, the touch electrode 700, which is reused as an optical structure 600, can be disposed on the side of the second support structure S2 facing away from the substrate 100.

[0195] In these alternative embodiments, by reusing at least a portion of the touch electrode 700 as the optical structure 600, the touch electrode 700 can be used to participate in the touch function of the display panel 10, and at the same time, the touch electrode 700 can also be used to participate in the 3D display of the display panel 10. This allows the display panel 10 to distribute the light emitted by the light-emitting device 400 without adding an additional film layer, which can improve the integration of the display panel 10 and reduce the thickness of the display panel 10.

[0196] Figure 19 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0197] like Figure 19 As shown, for ease of description, the following embodiments are illustrated by taking the example of a touch electrode 700, which is reused as an optical structure 600, being disposed on the side of the second support structure S2 away from the substrate 100.

[0198] In some optional embodiments, the touch electrode 700 includes a first portion 710 and a second portion 720. The first portion 710 and the second portion 720 are touch traces constituting the touch electrode 700. The second portion 720 is the touch trace that is close to the isolation opening 300a and can block the light-emitting device 400. The first portion 710 is disposed on the side of the second portion 720 away from the isolation opening 300a. The light transmittance of the second portion 720 is less than that of the first portion 710, and the second portion 720 is reused as a light-shielding structure 610.

[0199] Optionally, during the fabrication of the touch electrode 700, a portion of the material of the touch electrode 700 may be blackened to form a second portion 720 with lower light transmittance, while the remaining portion of the material of the touch electrode 700 that is not blackened may form a first portion 710 with higher light transmittance. Optionally, the extension and arrangement of the second portion 720 may refer to the extension and arrangement of the light-shielding structure 610 in any of the foregoing embodiments. For example, at least a portion of the second portion 720 may be extended along the first direction X and spaced apart in the second direction Y, and / or, at least a portion of the second portion 720 may be extended along the second direction Y and spaced apart in the first direction X.

[0200] In these alternative embodiments, the first portion 710 may not be reused as the optical structure 600. By setting the first portion 710 to have a higher light transmittance, the first portion 710 is less likely to cause excessive obstruction of the light emitted by the light-emitting device 400, thereby improving the display effect of the display panel 10. On the other hand, by setting the second portion 720 to have a lower light transmittance, the obstruction effect of the second portion 720 on the light emitted by the light-emitting device 400 can be improved, so that the second portion 720 can be reused as the light-shielding structure 610 to realize the 3D display of the display panel 10.

[0201] In some alternative embodiments, the thickness of the second portion 720 may be equal to the thickness of the first portion 710 to facilitate the fabrication of the touch electrode 700.

[0202] In some other alternative embodiments, such as Figure 19 As shown, the maximum thickness of the second portion 720 is greater than the maximum thickness of the first portion 710, so as to reduce the light transmittance of the second portion 720 and improve the blocking effect of the second portion 720 on the light emitted by the light-emitting device 400, so that the second portion 720 can be reused as a light-shielding structure 610 to realize the 3D display of the display panel 10.

[0203] Optionally, the touch electrode 700 includes a first portion 710 and a second portion 720 stacked together. The touch traces of the touch electrode 700 are all composed of the first portion 710 and the second portion 720 stacked together. The light transmittance of the second portion 720 is less than that of the first portion 710. The second portion 720 is reused as a light-shielding structure 610.

[0204] Figure 20 This is a partial structural diagram of an isolation structure 300 provided in an embodiment of this application. Figure 21 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0205] like Figure 20 and Figure 21As shown, an embodiment of the first aspect of this application also provides a display panel 10, including: a substrate 100; an isolation structure 300 disposed on one side of the substrate 100 and enclosing a plurality of isolation openings 300a; and a light-emitting device 400, at least partially located within the isolation openings 300a, wherein at least a portion of the isolation structure 300 is reused as an optical structure 600 and used to distribute the light emitted by the light-emitting device 400.

[0206] In a display panel 10 provided in this application embodiment, the display panel 10 includes a substrate 100, an isolation structure 300, a light-emitting device 400, and an optical structure 600. The isolation structure 300 is disposed on one side of the substrate 100 and encloses a plurality of isolation openings 300a. The light-emitting device 400 is at least partially located within the isolation openings 300a. The isolation structure 300 can be used to divide the sub-pixels of the display panel 10.

[0207] By reusing the isolation structure 300 as an optical structure 600, the isolation structure 300 can be used to divide the sub-pixels of the display panel 10, and at the same time, it can also be used to distribute the light emitted by the light-emitting device 400. This allows the image presented by the display panel 10 to be delivered to the user's left and right eyes respectively, so that the user's left and right eyes can receive different images with parallax. This enables the light-emitting display of the display panel 10 to produce a stereoscopic visual experience, thereby realizing naked-eye 3D display of the display panel 10. This allows the distribution of the light emitted by the light-emitting device 400 in the display panel 10 to be achieved without adding an additional film layer, which can improve the integration of the display panel 10 and reduce the thickness of the display panel 10.

[0208] Optionally, in a display panel 10 provided in this application embodiment, the substrate 100 may be the substrate 100 described in any of the foregoing embodiments. The light-emitting device 400 may also be the light-emitting device 400 described in any of the foregoing embodiments. For example, the light-emitting device 400 may include a first electrode 410, a light-emitting layer 420, and a second electrode 430 stacked together.

[0209] Optionally, the display panel 10 may also include the pixel definition layer 200 in any of the foregoing embodiments, and the isolation structure 300 may be disposed on the side of the pixel limiting portion 210 away from the substrate 100.

[0210] In some alternative embodiments, the isolation structure 300 includes a first isolation portion 310 and a second isolation portion 320 located on the side of the first isolation portion 310 away from the substrate 100, the second isolation portion 320 being disposed protruding from the first isolation portion 310 toward the isolation opening 300a.

[0211] Optionally, for the same second isolation portion 320, the second isolation portion 320 near the isolation opening 300a protrudes from the first isolation portion 310 by different distances, so that the second isolation portion 320 located on different sides of the first isolation portion 310 can have different overlapping areas with the adjacent light-emitting device 400, thereby blocking the light-emitting device 400 in different viewing directions of the left and right eyes, so that the images received by the left and right eyes are different.

[0212] By providing the second isolation portion 320 protruding from the first isolation portion 310 toward the isolation opening 300a, the second isolation portion 320 can block at least part of the material used to prepare the light-emitting layer 420 and the second electrode 430 when the light-emitting layer 420 and the second electrode 430 of the display panel 10 are deposited, thereby isolating the light-emitting layer 420 and the second electrode 430 between adjacent sub-pixels. This facilitates the formation of multiple spaced light-emitting layers 420 and the second electrode 430, thereby eliminating the need for a high-precision mask when depositing the light-emitting layer 420 and the second electrode 430 of the display panel 10. For example, it eliminates the need for a high-precision metal mask when depositing the light-emitting layer 420 and the second electrode 430, thereby significantly reducing the manufacturing cost of the display panel 10.

[0213] Optionally, the material of the isolation structure 300 may include a conductive material, and the second electrode 430 may be connected to the isolation structure 300, so that the second electrodes 430 in adjacent isolation openings 300a can be interconnected through the isolation structure 300 to form a surface electrode, so as to facilitate the control of the second electrode 430 in the display panel 10.

[0214] In some optional embodiments, the isolation structure 300 further includes a third isolation portion 330 disposed on the side of the first isolation portion 310 facing the substrate 100, the third isolation portion 330 protruding from the first isolation portion 310 toward the isolation opening 300a. The second electrode 430 can be connected to the third isolation portion 330. By making the third isolation portion 330 protrude from the first isolation portion 310 toward the isolation opening 300a, the third isolation portion 330 can have a larger size, facilitating the connection between the second electrode 430 and the third isolation portion 330, thereby improving the connection stability between the second electrode 430 and the isolation structure 300.

[0215] In some embodiments of this application, the optical structure 600 may include multiple light-shielding structures 610, and at least a portion of the isolation structure 300 may be reused as a light-shielding structure 610. The isolation structure 300 may have a low light transmittance to facilitate reuse as a light-shielding structure 610. The light-shielding structure 610 can be used to block the light emitted by the light-emitting device 400, distributing the light emitted by the light-emitting device 400 to the user's left and right eyes respectively, so that the light-shielding structure 610 can act as a grating structure to allow the user's left and right eyes to receive different images containing parallax. Specifically, the light-shielding structure 610 can act as a parallax barrier to enable the light-emitting display of the display panel 10 to produce a stereoscopic visual experience.

[0216] like Figure 20 As shown, in some optional embodiments, the optical structure 600 extends along the first direction X and is spaced apart in the second direction Y. For example, the isolation structure 300, which is reused as the light-shielding structure 610, can extend along the first direction X and be spaced apart in the second direction Y, so that the light-shielding structure 610 can better control the propagation path of the light emitted by the light-emitting device 400 in the second direction Y. When the distance between the user's left eye and right eye is the second direction Y, that is, when the user's left eye is located on the side of the right eye in the second direction Y, the user's left eye and right eye can receive different images with parallax in the second direction Y, thereby enabling the light-emitting display of the display panel 10 to produce a stereoscopic visual experience, so as to realize the naked-eye 3D display of the display panel 10.

[0217] Optionally, the optical structure 600 extends along the second direction Y and is spaced apart in the first direction X. For example, the isolation structure 300, which is reused as the light-shielding structure 610, can extend along the second direction Y and be spaced apart in the first direction X. This allows the light-shielding structure 610 to better control the propagation path of the light emitted by the light-emitting device 400 in the first direction X. When the distance between the user's left and right eyes is in the first direction X, that is, when the user's left eye is located on the side of the right eye in the first direction X, the user's left and right eyes can receive different images with parallax in the first direction X. This allows the light-emitting display of the display panel 10 to produce a stereoscopic visual experience, thereby realizing the naked-eye 3D display of the display panel 10.

[0218] Optionally, the orthographic projection of the light-shielding structure 610 onto the substrate 100 can be mesh-like. For example, the orthographic projection of the isolation structure 300 onto the substrate 100 can be mesh-like, so that when the distance between the user's left and right eyes is a first direction X, or when the distance between the user's left and right eyes is a second direction Y, the user's left and right eyes can receive different images containing parallax. This allows the user to experience stereoscopic vision when observing the display panel 10 from different angles, thereby improving the naked-eye 3D display effect of the display panel 10.

[0219] In some optional embodiments, the isolation effect of the isolation structure 300 on the light-emitting layer 420 and the second electrode 430 can be adjusted by adjusting the height of the isolation structure 300, thereby enabling adjustment of the spacing between the isolation structure 300, the light-emitting layer 420, and the second electrode 430. Specifically, by reasonably adjusting the height of the isolation structure 300, the light-emitting layer 420 can be spaced apart from the isolation structure 300 to reduce light emission crosstalk between adjacent sub-pixels and to allow the second electrode 430 to be better connected to the isolation structure 300, thereby improving the electrical connection effect between the second electrode 430 and the isolation structure 300.

[0220] Furthermore, by adjusting the height of the isolation structure 300, the degree to which the isolation structure 300 blocks the light emitted by the light-emitting device 400 can be adjusted, so as to better adjust the distribution effect of the light emitted by the light-emitting device 400 by the optical structure 600, thereby improving the naked-eye 3D display effect of the display panel 10.

[0221] Therefore, by reusing at least part of the isolation structure 300 as the optical structure 600, while adjusting the height of the isolation structure 300 to regulate its blocking effect on the light-emitting layer 420 and the second electrode 430, the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400 can also be adjusted accordingly.

[0222] Optionally, there are several ways to adjust the height of the isolation structure 300. For example, the height of at least one of the first isolation part 310, the second isolation part 320 and the third isolation part 330 can be adjusted to achieve the adjustment of the height of the isolation structure 300.

[0223] In some optional embodiments, the isolation structure 300's role in isolating the light-emitting layer 420 and the second electrode 430 can be adjusted by regulating the protrusion length of the second isolation portion 320 relative to the first isolation portion 310. This allows for adjustment of the spacing between the isolation structure 300, the light-emitting layer 420, and the second electrode 430. Specifically, by reasonably adjusting the protrusion length of the second isolation portion 320 relative to the first isolation portion 310, the light-emitting layer 420 can be spaced apart from the isolation structure 300 to reduce crosstalk between adjacent sub-pixels and to better connect the second electrode 430 to the isolation structure 300, thereby improving the electrical connection between the second electrode 430 and the isolation structure 300.

[0224] Furthermore, by adjusting the protruding length of the second isolation part 320 relative to the first isolation part 310, the degree of obstruction of the light emitted by the light-emitting device 400 by the isolation structure 300 can be adjusted, so as to better adjust the distribution effect of the light emitted by the light-emitting device 400 by the optical structure 600, thereby better improving the naked-eye 3D display effect of the display panel 10.

[0225] Therefore, by reusing at least a portion of the isolation structure 300 as the optical structure 600, while adjusting the protrusion length of the second isolation portion 320 relative to the first isolation portion 310 to adjust the isolation effect of the isolation structure 300 on the light-emitting layer 420 and the second electrode 430, the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400 can also be adjusted accordingly.

[0226] Optionally, at least some of the second isolation portions 320 have different protrusion lengths relative to the first isolation portion 310, so that different protrusion lengths of the second isolation portion 320 relative to the first isolation portion 310 can be set for the light-emitting device 400 at different positions, so that the user's left and right eyes can receive different images with parallax in the second direction Y, thereby enabling the light-emitting display of the display panel 10 to produce a stereoscopic visual experience, so as to realize the naked-eye 3D display of the display panel 10.

[0227] An embodiment of the second aspect of this application provides a display device, which includes the display panel 10 of any of the above embodiments. Since the display device provided by the second aspect of this application includes the display panel 10 of any of the first aspects, it has the beneficial effects of the display panel 10 of any of the first aspects, which will not be repeated here.
