[0087] Embodiments of the present application provide a display panel and a display device. Embodiments of the display panel and the display device will be described below in conjunction with the accompanying drawings.

[0088] Figure 1 1 is a partial cross-sectional view of a display panel 10 provided in an embodiment of the present 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 the present application provides a display panel 10, comprising: a substrate 100; an isolation structure 300, which is arranged on one side of the substrate 100 and encloses a plurality of isolation openings 300a; a light-emitting device 400, which is at least partially located in the isolation openings 300a; and an optical structure 600, which is arranged on a side of the isolation structure 300 away from the substrate 100, and is used to distribute light emitted by the light-emitting device 400.

[0090] In a display panel 10 provided in an embodiment of the present application, 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, and the light emitting device 400 is at least partially located in 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-emitting angles relative to the left and right eyes, so as to transmit the picture presented by the display panel 10 to the left eye and the right eye of the user respectively, so that the left eye and the right eye of the user can receive different pictures containing parallax, so that the light-emitting display of the display panel 10 can produce a stereoscopic visual experience, so as to realize the naked-eye 3D display of the display panel 10.

[0092] Among them, by setting 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, so as to better adjust the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400, thereby better improving the naked-eye 3D display effect of the display panel 10.

[0093] Optionally, adjusting the height of the isolation structure 300 may refer to adjusting the size 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 output 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 at least partially extend to the isolation opening 300a. For example, the optical structure 600 may at least partially extend into the isolation opening 300a, or the optical structure 600 may at least partially extend 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 output angle of the sub-pixel.

[0096] Optionally, the optical structure 600 is arranged on the side of the isolation structure 300 facing away from the substrate 100, which may 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 setting of the isolation structure 300 can better affect 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 output angle of the sub-pixel relative to the left and right eyes through height changes.

[0097] In some embodiments of the present application, there are multiple ways to set the substrate 100. 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 that are stacked. Exemplarily, the driving circuit 150 may include a transistor 151, a storage capacitor 152, and a driving signal line for connecting various devices. The transistor 151 includes a semiconductor, a gate 151a, and a source and drain 151b. The storage capacitor 152 includes a first plate 152a and a second plate 152b. As an example, the gate 151a and the first plate 152a may be located on the side of the first insulating layer 120 facing the substrate 110, the second plate 152b may be located between the first insulating layer 120 and the second insulating layer 130, and the source and drain 151b may be located between the second insulating layer 130 and the third insulating layer 140.

[0098] In some optional embodiments, in a 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 which are sequentially stacked.

[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 be used as pixel electrodes of the display panel 10, one of the first electrode 410 and the second electrode 430 can be used as an anode, and the other can be used as a cathode to drive the light-emitting layer 420 to emit light. The embodiment of the present application is described by taking 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 as an example.

[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 defining portion 210 and a pixel opening 220 formed by the pixel defining portion 210. The pixel opening 220 may be connected to the isolation structure 300. The light-emitting device 400 may also be at least partially located in 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 the present application, there are many ways to set the relative position between the pixel defining portion 210 and the isolation structure 300, for example, Figure 1 As shown, the isolation structure 300 may be disposed on the side of the pixel defining portion 210 away from the substrate 100, that is, the isolation structure 300 may be directly disposed on the pixel defining portion 210. Or, for example, the pixel defining portion 210 may be provided with a receiving groove, and at least part of the isolation structure 300 may be located in the receiving groove, so that the isolation structure 300-500 is not likely to have an excessive height compared to the substrate 100, thereby being able to better reduce the thickness of the display panel 10. For ease of description, the following embodiments are described by taking the isolation structure 300 disposed on the side of the pixel defining portion 210 away from the substrate 100 as an example.

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

[0104] By arranging the second isolation portion 320 to protrude from the first isolation portion 310 toward the isolation opening 300a, when the light-emitting layer 420 and the second electrode 430 of the display panel 10 are evaporated, the second isolation portion 320 can block at least a portion of the material used to prepare the light-emitting layer 420 and the second electrode 430 to separate the light-emitting layer 420 and the second electrode 430 between adjacent sub-pixels, which can facilitate the formation of a plurality of spaced light-emitting layers 420 and second electrodes 430, thereby eliminating the need to set a mask with high precision when evaporating the light-emitting layer 420 and the second electrode 430 of the display panel 10. For example, there is no need to set a high-precision metal mask (Fine Metal Mask, FMM) when evaporating the light-emitting layer 420 and the second electrode 430, thereby effectively reducing the production 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, and the third isolation portion 330 is disposed protruding from the first isolation portion 310 toward the isolation opening 300a. The second electrode 430 may be connected to the third isolation portion 330, and by protruding from the first isolation portion 310 toward the isolation opening 300a, the third isolation portion 330 may have a larger size, so as to facilitate the connection between the second electrode 430 and the third isolation portion 330, and the connection stability between the second electrode 430 and the isolation structure 300 may be improved.

[0107] In the aforementioned optional embodiment, the height of the isolation structure 300 can be adjusted to adjust the isolation structure 300's partitioning effect on the light-emitting layer 420 and the second electrode 430, so as to adjust 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 the light crosstalk between adjacent sub-pixels, and the second electrode 430 can be well connected to the isolation structure 300 to improve the electrical connection effect between the second electrode 430 and the isolation structure 300. Therefore, by arranging 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 the isolation structure 300's partitioning effect on the light-emitting layer 420 and the second electrode 430, the optical structure 600 can also be adjusted accordingly. The distribution effect of the light emitted by the light-emitting device 400.

[0108] In some embodiments of the present application, there are multiple 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, which can be used to shield the light emitted by the light emitting device 400, so as to distribute the light emitted by the light emitting device 400 to the left eye and the right eye of the user, respectively, so that the light shielding structure 610 can be used as a grating structure to allow the left eye and the right eye of the user to receive different pictures with parallax. Specifically, the light shielding structure 610 can be used as a parallax barrier to enable the light display of the display panel 10 to produce a stereoscopic visual experience.

[0110] Figure 2 6 is a schematic diagram of a light shielding structure 610 provided in an embodiment of the present application. The X direction in the figure is the first direction X, and the Y direction in the figure is the second direction Y. The first direction X, the second direction Y and the thickness direction Z of the display panel 10 may intersect each other. For example, the first direction X, the second direction Y and the thickness direction Z of the display panel 10 may be perpendicular to each other.

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

[0112] Figure 3 It is a structural schematic diagram of a light-shielding structure 610 provided in another embodiment of the present application.

[0113] Optional, such as Figure 3As shown, the multiple shading structures 610 include a first shading structure and a second shading structure that are cross-arranged. The first shading structure is extended and formed along the first direction X and is spaced apart in the second direction Y. The second shading structure is extended and formed along the second direction Y and is spaced apart in the first direction X, so that the shading structure 610 can better regulate the propagation light path of the light emitted by the light-emitting device 400 in the first direction X, so that when the spacing direction between the left eye and the right eye of the user is the first direction X, that is, when the left eye of the user is located on one side of the right eye in the first direction X, the left eye and the right eye of the user can receive different pictures with parallax in the first direction X, so that the luminous display of the display panel 10 can produce a stereoscopic visual experience, so as to realize the naked-eye 3D display of the display panel 10.

[0114] Optional, such as Figure 3 As shown, a plurality of light-shielding structures 610 form a plurality of light-transmitting openings arranged in an array, and the orthographic projections of the light-transmitting openings on the substrate 100 partially overlap with the orthographic projections of the light-emitting device 400 on the substrate 100. The orthographic projections of the light-shielding structures 610 on the substrate 100 may be mesh-shaped and may partially block the light-emitting device 400, so that when the spacing direction between the left eye and the right eye of the user is the first direction X, or when the spacing direction between the left eye and the right eye of the user is the second direction Y, the left eye and the right eye of the user may both receive different images containing parallax, so that when the user observes the display panel 10 from different angles, the user may have a stereoscopic visual experience, thereby being able to better improve 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 ​​the orthographic projection of a portion of the shading 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 ​​the orthographic projection of another portion of the shading structure 610 on the substrate 100 and the orthographic projection of the light-emitting device 400 on the substrate 100, so that at least some of the different shading structures 610 block different degrees of light emitted by different light-emitting devices 400, so as to transmit the picture presented by the display panel 10 to the left eye and the right eye of the user respectively, so that the left eye and the right eye of the user can receive different pictures with parallax.

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

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

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

[0119] Figure 4 It is a partial cross-sectional view of a display panel 10 provided in yet another embodiment of the present 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 facing away from the substrate 100 , and the optical structure 600 is disposed on the side of the at least one encapsulation layer 500 facing 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 arranging the optical structure 600 on the side of at least one encapsulation layer 500 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 at least one encapsulation layer 500, so as to better adjust the distribution effect of the optical structure 600 on the light emitted by the light emitting device 400. In addition, when the optical structure 600 needs to be patterned, for example, when the material of the light shielding structure 610 is patterned, the encapsulation layer 500 provides certain protection to the light emitting device 400 and the isolation structure 300, so that the etching material is not easy to cause etching damage to the light emitting device 400 and the isolation structure 300, so as to better improve the structural reliability of the display panel 10.

[0122] In some optional embodiments, at least one encapsulation layer 500 includes a first-type 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-type encapsulation layer 510 includes encapsulation units 511 arranged corresponding to each isolation opening 300a.

[0123] Optionally, the packaging unit 511 provided corresponding to each isolation opening 300 a may mean that a packaging unit 511 is provided in each isolation opening 300 a , and each packaging unit 511 is provided corresponding to only one isolation opening 300 a .

[0124] Optionally, adjacent encapsulation units 511 are spaced apart from each other.

[0125] Optionally, the material of the first type encapsulation layer 510 includes inorganic material.

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

[0127] In these optional embodiments, the packaging unit 511 can be used to perform relatively independent packaging of the light-emitting devices 400 in different isolation openings 300a, that is, each light-emitting device 400 in the isolation opening 300a has at least one corresponding packaging unit 511 for corresponding packaging, so that when a packaging unit 511 fails to package the light-emitting device 400 in the isolation opening 300a, it is not easy to affect the packaging effect of the adjacent packaging unit 511, so as to better improve the packaging effect of the packaging layer 500.

[0128] In some optional embodiments, the optical structure 600 may be disposed on a side of the packaging unit 511 facing away from the substrate 100 .

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

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

[0131] In these optional embodiments, by arranging at least part of the optical structure 600 on the side of the packaging unit 511 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 packaging unit 511, so as to better adjust 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 packaging unit 511, so as to better adjust the shielding effect of the light shielding structure 610 on the light emitted by the light emitting device 400, so that the light shielding structure 610 is not likely to have a large shielding effect on the light emitted by the light emitting device 400, and the risk of unnecessary light leaking from the light shielding structure 610 can be reduced, so as to better regulate the propagation optical path of the light emitted by the light emitting device 400 in the second direction Y, and realize the naked eye 3D display of the display panel 10.

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

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

[0134] In these optional embodiments, by arranging the optical structure 600 on the side of the first packaging part 511a above the isolation structure 300 away from the substrate 100, the film material of the isolation structure 300 and the first packaging part 511a can be stacked below the optical structure 600, and by adjusting the height of the isolation structure 300 and the thickness of the first packaging part 511a at the same time, the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400 can be better adjusted. In addition, when the optical structure 600 includes a shading structure 610, by arranging the shading structure 610 on the first packaging part 511a, the shading structure 610 is not likely to have a significant shielding effect on the light emitted by the light-emitting device 400, thereby improving the working reliability of the shading structure 610.

[0135] Optionally, the first packaging portion 511 a and the isolation structure 300 are spaced apart, so that the distance between the first packaging portion 511 a 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 also 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, and 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] Among them, the third packaging part 511c can be mainly used to package the light-emitting device 400. The second packaging part 511b connected to the third packaging part 511c and the first packaging part 511a connected to the second packaging part 511b can effectively extend the packaging path of the packaging 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 packaging unit 511, thereby better improving the packaging effect of the display panel 10.

[0138] Figure 5 It is a partial cross-sectional view of a display panel 10 provided in yet another embodiment of the present application.

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

[0140] Optionally, at least a portion of the light shielding structure 610 may be disposed on a side of the first supporting structure S1 facing 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 packaging 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 packaging 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 is flush with the side of the first packaging portion 511a facing away from the substrate 100.

[0142] When the side of the first supporting structure S1 facing away from the substrate 100 is lower than the side of the first packaging portion 511a facing away from the substrate 100, the optical structure 600 disposed on the side of the first supporting structure S1 facing away from the substrate 100 may be partially located in 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 packaging portion 511a facing away from the substrate 100 and the substrate 100. Alternatively, the first support structure S1 may also fill the space between the first packaging portion 511a and the isolation structure 300.

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

[0145] Optionally, when the distance between the surface of the first supporting structure S1 facing away from the substrate 100 and the substrate 100 is greater than the distance between the surface of the first packaging portion 511a facing away from the substrate 100 and the substrate 100, the optical structure 600 can be arranged on the side of the first supporting 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 supporting 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 supporting structure S1 may have good light transmittance to reduce the shielding effect of the first supporting structure S1 on the light emitted by the light-emitting device 400 , thereby improving the light-emitting display effect of the display panel 10 .

[0147] In these optional embodiments, when the thickness of the first type packaging layer 510 is relatively thin and is easily uneven in the isolation opening 300a, that is, the first type packaging layer 510 located in the isolation opening 300a has a large undulating height difference, the first supporting structure S1 arranged on the side of the packaging unit 511 away from the substrate 100 can play a better flattening role, that is, the surface of the side of the first supporting structure S1 away from the substrate 100 can be relatively flat, and by arranging at least part of the optical structure 600 on the side of the first supporting structure S1 away from the substrate 100, it is not easy for adjacent optical structures 600 and the optical structure 600 itself to produce a large height difference, which can facilitate the arrangement of the optical structure 600.

[0148] Optionally, the material of the first support structure S1 includes an organic material, so that when preparing the first support structure S1, the material of the first support structure S1 can have good fluidity, so that the surface of the first support structure S1 formed on one side away from the substrate 100 can have good flatness, so as to facilitate the arrangement of the optical structure 600. For example, the first support structure S1 can include one of photoresist, transparent optical glue, and leveling organic glue.

[0149] Optionally, at least part 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 color of the light emitting device 400 located on the side of the first support structure S1 close to the substrate 100, so that the light emitted by the light emitting device 400 can be emitted outward through the color filter.

[0150] By reusing at least part of the first support structure S1 as a color resist, the color resist of the display panel 10 can be arranged in the isolation opening 300a to reduce the thickness of the display panel 10, and the color resist can also play a better supporting role for the optical structure 600. In addition, the height of the optical structure 600 relative to the light emitting device 400 can be adjusted by adjusting the thickness of the color resist, so as to better adjust the distribution effect of the optical structure 600 on the light emitted by the light emitting device 400.

[0151] When the optical structure 600 includes the shading structure 610 , the shading structure 610 can also effectively reduce the reflectivity of the display panel 10 , so that the display panel 10 is less likely to generate reflection when performing luminous display.

[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 transmit the light emitted by the light-emitting device 400 to the left eye and the right eye of the user at different light-emitting angles, respectively, so that the left eye and the right eye of the user can receive different pictures containing parallax.

[0154] Optionally, the lens structure 620 includes a plurality of lens units 621, which are extended and formed along the first direction X and are arranged side by side in the second direction Y, so that the lens units can better regulate the propagation path of the light emitted by the light-emitting device 400 in the second direction Y by refraction, so that when the interval direction between the user's left eye and the right eye is the second direction Y, that is, when the user's left eye is located on one side of the right eye in the second direction Y, the user's left eye and right eye can receive different pictures with parallax in the second direction Y, so that the luminous display of the display panel 10 can produce a stereoscopic visual experience, so as to realize the naked-eye 3D of the display panel 10.

[0155] In some embodiments of the present application, there are many ways to implement the refraction and splitting of the lens unit 621, and the refraction and splitting of the lens unit 621 can be adjusted by adjusting the surface morphology of the side of the lens unit 621 away from the substrate 100. Figure 7 As shown, the lens unit 621 may include a prism. Figure 8 As shown, at least a portion of the lens unit 621 has a surface facing away from the substrate 100 that is a curved surface.

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

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

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

[0196] Fig.19 It is a partial cross-sectional view of a display panel 10 provided in another embodiment of the present application.

[0197] like Fig.19 As shown, for the convenience of describing the following embodiments, the touch electrodes 700 multiplexed as the optical structure 600 are arranged on the side of the second supporting structure S2 away from the substrate 100 as an example.

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

[0200] In these optional embodiments, the first subdivision 710 may not be multiplexed into the optical structure 600. By setting the first subdivision 710 to have a higher light transmittance, the first subdivision 710 is not likely to cause excessive shielding effect on the light emitted by the light-emitting device 400, so as to improve the display effect of the display panel 10. By setting the second subdivision 720 to have a lower light transmittance, the shielding effect of the second subdivision 720 on the light emitted by the light-emitting device 400 can be improved, so that the second subdivision 720 can be multiplexed into the shading structure 610 to realize 3D display of the display panel 10.

[0201] In some optional embodiments, the thickness of the second section 720 may be equal to the thickness of the first section 710 to facilitate the preparation of the touch electrode 700 .

[0202] In some other optional embodiments, such as Fig.19 As shown, the maximum thickness of the second division 720 is greater than the maximum thickness of the first division 710, so as to reduce the light transmittance of the second division 720 and better improve the shielding effect of the second division 720 on the light emitted by the light-emitting device 400, so as to facilitate the reuse of the second division 720 as the shading structure 610 to realize the 3D display of the display panel 10.

[0203] Optionally, the touch electrode 700 includes a first division 710 and a second division 720 that are stacked, and the touch lines of the touch electrode 700 are composed of the first division 710 and the second division 720 that are stacked. The transmittance of the second division 720 is less than that of the first division 710, and the second division 720 is reused as a shading structure 610.

[0204] Fig. 20 is a partial structural diagram of an isolation structure 300 provided in an embodiment of the present application, Fig.21 It is a partial cross-sectional view of a display panel 10 provided in another embodiment of the present application.

[0205] like Fig. 20 and Fig.21As shown, an embodiment of the first aspect of the present application also provides a display panel 10, comprising: a substrate 100; an isolation structure 300, which is arranged on one side of the substrate 100 and encloses a plurality of isolation openings 300a; a light-emitting device 400, which is at least partially located in the isolation opening 300a, wherein at least part of the isolation structure 300 is multiplexed as an optical structure 600 and is used to distribute light emitted by the light-emitting device 400.

[0206] In a display panel 10 provided in an embodiment of the present application, 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, and the light emitting device 400 is at least partially located in 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 the optical structure 600, the isolation structure 300 can be used to divide the sub-pixels of the display panel 10, and the isolation structure 300 can also be used to distribute the light emitted by the light-emitting device 400, so as to transmit the picture presented by the display panel 10 to the left eye and the right eye of the user respectively, so that the left eye and the right eye of the user can receive different pictures with parallax, so that the luminous display of the display panel 10 can produce a stereoscopic visual experience, so as to realize the naked-eye 3D display of the display panel 10, so that the display panel 10 can distribute the light emitted by the light-emitting device 400 without adding an additional film layer, which can better improve the integration of the display panel 10 and can better reduce the thickness of the display panel 10.

[0208] Optionally, in a display panel 10 provided in an embodiment of the present application, 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, a light-emitting layer 420, and a second electrode 430 that are stacked.

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

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

[0211] Optionally, for the same second isolation portion 320, the second isolation portion 320 close to the isolation opening 300a protrudes from the first isolation portion 310 at 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 having different shielding for the light-emitting device 400 in different viewing angles of the left and right eyes, thereby achieving different images received by the left and right eyes.

[0212] By arranging the second isolation portion 320 to protrude from the first isolation portion 310 toward the isolation opening 300a, when the light-emitting layer 420 and the second electrode 430 of the display panel 10 are evaporated, the second isolation portion 320 can block at least a portion of the material used to prepare the light-emitting layer 420 and the second electrode 430, so as to separate the light-emitting layer 420 and the second electrode 430 between adjacent sub-pixels, which can facilitate the formation of a plurality of spaced light-emitting layers 420 and second electrodes 430, thereby eliminating the need to set a mask with high precision when evaporating the light-emitting layer 420 and the second electrode 430 of the display panel 10. For example, there is no need to set a high-precision metal mask when evaporating the light-emitting layer 420 and the second electrode 430, thereby effectively reducing the production 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, and the third isolation portion 330 is disposed protruding from the first isolation portion 310 toward the isolation opening 300a. The second electrode 430 may be connected to the third isolation portion 330, and by protruding from the first isolation portion 310 toward the isolation opening 300a, the third isolation portion 330 may have a larger size, so as to facilitate the connection between the second electrode 430 and the third isolation portion 330, and the connection stability between the second electrode 430 and the isolation structure 300 may be improved.

[0215] In some embodiments of the present application, the optical structure 600 may include a plurality of shading structures 610, and at least a portion of the isolation structure 300 may be reused as the shading structure 610. Among them, the isolation structure 300 may have a lower transmittance to facilitate reuse as the shading structure 610. The shading structure 610 may be used to block the light emitted by the light-emitting device 400 to distribute the light emitted by the light-emitting device 400 to the left eye and the right eye of the user, respectively, so that the shading structure 610 can be used as a grating structure to allow the left eye and the right eye of the user to receive different pictures with parallax. Specifically, the shading structure 610 can be used as a parallax barrier to enable the light-emitting display of the display panel 10 to produce a stereoscopic visual experience.

[0216] like Fig. 20 As shown, in some optional embodiments, the optical structure 600 is extended and formed along the first direction X and is spaced apart in the second direction Y. For example, the isolation structure 300 multiplexed as the shading structure 610 can be extended and formed along the first direction X and is spaced apart in the second direction Y, so that the shading structure 610 can better regulate the propagation light path of the light emitted by the light-emitting device 400 in the second direction Y, so that when the spacing direction between the left eye and the right eye of the user is the second direction Y, that is, when the left eye of the user is located on one side of the right eye in the second direction Y, the left eye and the right eye of the user can receive different pictures with parallax in the second direction Y, so that the luminous display of the display panel 10 can 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 is extended and formed along the second direction Y and is spaced apart in the first direction X. For example, the isolation structure 300 multiplexed as the shading structure 610 can be extended and formed along the second direction Y and be spaced apart in the first direction X, so that the shading structure 610 can better regulate the propagation path of the light emitted by the light-emitting device 400 in the first direction X, so that when the spacing direction between the left eye and the right eye of the user is the first direction X, that is, when the left eye of the user is located on one side of the right eye in the first direction X, the left eye and the right eye of the user can receive different pictures with parallax in the first direction X, so that the luminous display of the display panel 10 can produce a stereoscopic visual experience, so as to realize the naked-eye 3D display of the display panel 10.

[0218] Optionally, the orthographic projection of the shading structure 610 on the substrate 100 may be in a mesh shape. For example, the orthographic projection of the isolation structure 300 on the substrate 100 may be in a mesh shape, so that when the spacing direction between the user's left eye and the right eye is the first direction X, or when the spacing direction between the user's left eye and the right eye is the second direction Y, the user's left eye and right eye can both receive different pictures containing parallax, so that when the user observes the display panel 10 at different angles, the user can have a stereoscopic visual experience, thereby better improving the naked-eye 3D display effect of the display panel 10.

[0219] In some optional embodiments, the isolation structure 300 can be adjusted to separate the light emitting layer 420 from the second electrode 430 by adjusting the height of the isolation structure 300, so as to adjust 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 the light crosstalk between adjacent sub-pixels, and the second electrode 430 can be better connected to the isolation structure 300 to improve the electrical connection effect between the second electrode 430 and the isolation structure 300.

[0220] Moreover, 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 also be adjusted, so as to better adjust the distribution effect of the optical structure 600 on the light emitted by the light-emitting device 400 , thereby better 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 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.

[0222] Optionally, there are various ways to adjust the height of the isolation structure 300 . For example, the height of at least one of the first isolation portion 310 , the second isolation portion 320 , and the third isolation portion 330 may be adjusted to adjust the height of the isolation structure 300 .

[0223] 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 protruding length of the second isolation portion 320 relative to the first isolation portion 310, so as to adjust the spacing between the isolation structure 300 and the light-emitting layer 420 and the second electrode 430. Specifically, by reasonably adjusting the protruding 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 the light crosstalk between adjacent sub-pixels, and the second electrode 430 can be better connected to the isolation structure 300 to improve the electrical connection effect between the second electrode 430 and the isolation structure 300.

[0224] Moreover, by adjusting the protruding length of the second isolation portion 320 relative to the first isolation portion 310, 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 optical structure 600 on the light emitted by the light-emitting device 400, thereby better improving the naked-eye 3D display effect of the display panel 10.

[0225] Therefore, by reusing at least part of the isolation structure 300 as the optical structure 600, while adjusting the protruding 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 part of the second isolation portion 320 has a different protruding length relative to the first isolation portion 310, so that different protruding lengths of the second isolation portion 320 relative to the first isolation portion 310 can be set for the light-emitting devices 400 at different positions, so that the user's left eye and right eye can receive different pictures with parallax in the second direction Y, so that the luminous display of the display panel 10 can produce a stereoscopic visual experience, thereby realizing the naked-eye 3D display of the display panel 10.
