[0104] In this optional embodiment, there are various ways to set the insulation between the shielding structure 500 and the isolation structure 400. For example, the shielding structure 500 may be spaced apart from the isolation structure 400, or an insulating material may be provided between the shielding structure 500 and the isolation structure 400 to achieve insulation. This application does not make any specific limitations on this.

Optionally, the second shielding structure 520 may be disposed between any two film structures of the substrate 100 on the side of the driving circuit away from the substrate 110. For example, the second shielding structure 520 may be disposed between the planarization layer 130 and the third insulating layer 123.

For example, the second shielding structure 520 and the first electrode layer 200 are arranged in the same layer. By arranging the second shielding structure 520 and the first electrode layer 200 in the same layer, the second shielding structure 520 can be prepared in the same process step as the first electrode layer 200. Therefore, by setting the second shielding structure 520 to limit the mutual interference between the touch signal and other signals in the display panel 10, it is also possible to simplify the preparation process of the display panel 10 and improve the preparation efficiency of the display panel 10.

[0114] Optionally, the second shielding structure 520 has the same shape as the first electrode 210; and / or, the second shielding structure 520 has the same size as the first electrode 210, so that the second shielding structure 520 can be prepared using the same processing equipment and the same process step as the first electrode 210, which can further improve the preparation efficiency of the display panel 10.

[0115] For the convenience of description, the following embodiments are described by taking the second shielding structure 520 and the first electrode layer 200 as an example.

[0116] In some optional embodiments, the isolation structure 400 may be used to separate the materials of the adjacent light-emitting units 610 and the materials of the second electrode 710.

[0126] Optionally, the first shielding structure 510 includes a first sub-portion 511 arranged in the same layer as the isolation portion 410, the first sub-portion 511 includes a third end 511a facing the substrate 100 and a fourth end 511b away from the substrate 100, and the orthographic projection of the third end 511a on the substrate 100 is located within the orthographic projection of the fourth end 511b on the substrate 100, so that the first shielding structure 510 can be approximately the same shape as the isolation structure 400, so that the first shielding structure 510 and the isolation structure 400 can be prepared in the same process step.

[0127] In some embodiments of the present application, there are many ways to set the shapes of the isolation portion 410 and the first sub-portion 511. The shape of the isolation portion 410 can be any shape that can shield and isolate the material of the light-emitting layer 600.

[0128] like Figure 6 As shown, in some embodiments, in the direction away from the substrate 100, the distance between the surfaces of the isolation portion 410 on both sides of the light-emitting unit 610 gradually increases, and the distance between the surfaces of the first sub-portion 511 on both sides of the second shielding structure 520 gradually increases, so as to form a shape in which the orthographic projection of the first end 410a of the isolation portion 410 on the substrate 100 is located within the orthographic projection of the second end 410b on the substrate 100, and to facilitate the formation of a shape in which the orthographic projection of the third end 511a of the first sub-portion 511 on the substrate 100 is located within the orthographic projection of the fourth end 511b on the substrate 100.

[0134] like Figure 8 As shown, in some optional embodiments, the first shielding structure 510 can be connected to the second shielding structure 520 through the via 10b, so that it is difficult to generate capacitance between the first shielding structure 510 and the second shielding structure 520, and the shielding structure 500 itself is also difficult to interfere with the touch signal in the touch component 10a and the signal in the substrate 100, thereby better improving the working reliability of the display panel 10.

[0135] Fig. 9 It is a schematic diagram of a partial structure of a second pixel defining portion 320 provided in an embodiment of the present application.

[0136] like Figure 8 and Fig. 9As shown, optionally, the via 10b can be arranged around at least a portion of the second shielding structure 520, so that the material in the via 10b used to connect the first shielding structure 510 and the second shielding structure 520 can also play a good shielding and shielding role between the touch signal and other signals in the display panel 10, so that the touch signal and other signals in the display panel 10 are not easy to interfere with each other in the gap between the first shielding structure 510 and the second shielding structure 520, thereby further improving the working reliability of the display panel 10.

[0137] For example, the via 10b can be arranged around at least a portion of the second shielding structure 520, and at least a portion of the first shielding structure 510 can fall into the via 10b and connect with the second shielding structure 520, so that the first shielding structure 510 in the via 10b can also play a better shielding and shielding role between the touch signal and other signals in the display panel 10, so that the touch signal and other signals in the display panel 10 are not easy to interfere with each other in the gap between the first shielding structure 510 and the second shielding structure 520, so that the shielding structure 500 can play a more continuous shielding and shielding effect in the non-display area NA.

[0138] Optionally, the orthographic projection of the first shielding structure 510 on the substrate 100 and the orthographic projection of the second shielding structure 520 on the substrate 100 are at least partially overlapped, so that the first shielding structure 510 is connected to the second shielding structure 520 through the via 10b.

By arranging the conductive portion 420 to protrude from the isolation portion 410 toward the light-emitting unit 610, that is, by arranging the conductive portion 420 to protrude from the isolation portion 410 toward the isolation opening 400a, it is possible to facilitate the overlap between the second electrode 710 and the conductive portion 420, and the overlap area between the conductive portion 420 and the second electrode 710 can be improved, and the overlap resistance of the display panel 10 can be reduced, so that it is possible to facilitate the electrical connection between adjacent second electrodes 710 through the isolation portion 410.

[0144] Optionally, the second sub-portion 512 and the conductive portion 420 are provided in the same layer and with the same material, so that the second sub-portion 512 and the conductive portion 420 can be prepared in the same process step.

By disposing at least part of the second pixel defining portion 320 on the side of the second shielding structure 520 away from the substrate 100, when preparing the first shielding structure 510, for example, when preparing the shielding opening 510a of the first shielding structure 510, the second pixel defining portion 320 may play a better protective role on the second shielding structure 520, so that the etching material is not likely to damage the second shielding structure 520.

[0148] In some optional embodiments, the second pixel defining portion 320 is provided with a through hole 340, and the through hole 340 can be used to release the water vapor in the display panel 10, so that the display panel 10 is not easily damaged by the water vapor pressure. For example, the through hole 340 can be used to release the water vapor generated during the re-processing process (such as baking) of a part of the organic material layer structure (such as the planarization layer 130) of the display panel 10, and the through hole 340 can also be used to release the water vapor generated in the reliability test of the display panel 10 (simulating the user usage scenario).

[0149] Optionally, the through hole 340 may be located on a side of the shielding structure 500 away from the display area AA.

[0150] Optionally, the orthographic projection of the shielding structure 500 on the pixel definition layer 300 is staggered with the through hole 340 .

[0151] By properly setting the position of the through hole 340 , the setting of the through hole 340 is less likely to affect the continuity of the shielding structure 500 , so that the shielding structure 500 can better limit the transmission of the signal in the substrate 100 to the touch control component 10 a .

[0152] In some optional embodiments, the through hole 340 may be disposed around at least a portion of the shielding structure 500 , so that the through hole 340 may have a better extension size to enhance the release effect of the through hole 340 on water vapor.

[0153] In this optional embodiment, the through holes 340 may be arranged in various shapes and forms. For example, the through holes 340 may be annular to better surround the shielding structure 500. Or for example, there are multiple through holes 340, and the multiple through holes 340 are arranged at intervals around the shielding structure 500.

[0162] Optionally, the material of the second encapsulation layer 820 includes an inorganic material.

[0163] Optionally, the first encapsulation layer 810 and the second encapsulation layer 820 are made of the same material. By setting the first encapsulation layer 810 and the second encapsulation layer 820 to be the same material, the first encapsulation layer 810 can be better bonded to the second encapsulation layer 820, making the first encapsulation layer 810 less likely to peel off and fall off.

[0164] Optionally, the thickness of the first encapsulation layer 810 may be smaller than the thickness of the second encapsulation layer 820, so that the first encapsulation layer 810 located in the non-display area NA is not prone to have an excessively large thickness, thereby reducing the impact of the first encapsulation layer 810 on the subsequent preparation of the display panel 10. For example, the impact of the first encapsulation layer 810 on subsequent shearing or bending processes can be reduced.

[0166] Optionally, the dam 900 may be disposed on a side of the driving circuit layer 120 facing the planarization layer 130. Optionally, the dam 900 may be spaced apart from the planarization layer 130 so that the dam 900 can limit the position of the organic material in the third encapsulation layer 830.

[0167] Optionally, at least part of the dam 900 may be provided in the same layer and the same material as the planarization layer 130, so as to further simplify the manufacturing process of the display panel 10 and improve the manufacturing efficiency of the display panel 10. For example, the dam 900 may be formed by stacking multiple layers of materials, and in a direction away from the driving circuit layer 120, the dam 900 may include a first dam layer 910 and a second dam layer 920 stacked in sequence, wherein when the planarization layer 130 is prepared, at least part of the material of the planarization layer 130 may fall onto the first dam layer 910 to form the second dam layer 920.

A through hole 340 may also be provided on the third pixel defining portion 330 to release water vapor in the display panel 10 so that the display panel 10 is not easily damaged by water vapor pressure.

[0169] In some optional embodiments, there is a first spacing L1 between the surface of the dam 900 facing away from the driving circuit layer 120 and the surface of the driving circuit layer 120 facing the planarization layer 130, and the maximum spacing between the surface of the shielding structure 500 facing away from the driving circuit layer 120 and the surface of the driving circuit layer 120 facing the planarization layer 130 is a second spacing L2, and the second spacing L2 is greater than the first spacing L1.

[0170] Optionally, there is a third distance L3 between the orthographic projection of the shielding structure 500 on the substrate 100 and the orthographic projection of the dam 900 on the substrate 100 , and the third distance L3 is greater than or equal to 100 μm.

[0171] Optionally, the third interval L3 is greater than or equal to 100 μm and less than or equal to 150 μm. For example, the third interval L3 may be equal to 120 μm, 130 μm, 140 μm or 150 μm.

[0172] In these optional embodiments, when there is a height difference between the dam 900 of the non-display area NA and the shielding structure 500, that is, when the second spacing L2 is greater than the first spacing L1, by reasonably setting the third spacing L3, there can be a relatively sufficient buffer space between the dam 900 and the shielding structure 500, so that the thickness of the third encapsulation layer 830 can be gradually reduced in the buffer space, so that when the third encapsulation layer 830 is prepared, the material of the third encapsulation layer 830 that flows to the dam 900 is not prone to have too large a thickness, so that the dam 900 can play a better limiting role on the organic material of the third encapsulation layer 830.
