[0072] Organic light emitting diode (OLED) display technology is considered as the most potential new flat panel display technology in the next generation. Compared with liquid crystal display technology, OLED display technology has the advantages of low power consumption, low cost, self-luminous, wide viewing angle and fast response speed.

[0073] In the implementation of the present application, the inventors found that the related art has the following problems: a display panel can include a substrate, a partition structure disposed on the substrate, a plurality of light emitting units, and a plurality of encapsulation portions. The partition structure defines a plurality of partition openings. The light emitting units are at least partially disposed in the partition openings. The encapsulation portions are disposed on a side of the light emitting units away from the substrate and extend to a side of the partition structure away from the substrate. The boundaries of the encapsulation portions on both sides in the first direction can be captured by a size measuring instrument, so as to measure the distance between the boundaries of the encapsulation portions on both sides in the first direction, to obtain the size of the encapsulation portions in the first direction, and further obtain the size of the pixels of the display panel in the first direction.

[0074] However, it is difficult to measure the size between the boundaries of the encapsulation portions on both sides in the first direction, and further to measure the size of the pixels in the first direction.

[0075] In view of at least one of the above problems, embodiments of the present application provide a display panel and a display device, which can reduce the difficulty of measuring the size between the boundaries of the encapsulation portions on both sides in the first direction, to reduce the difficulty of measuring the size of the pixels of the display panel in the first direction, and improve the measurement accuracy of the size of the pixels in the first direction.

[0076] The following will be described in conjunction with Figures 1-9The display device provided in the embodiments of the present application is described.

[0077] The display device provided in the embodiments of the present application can include a display panel 100. The display device can be electronic paper, a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a smart bracelet, a smart watch, a super personal computer, a navigator, a wireless device, a personal data assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a video camera, a game console, a clock, a calculator, a television monitor, a computer monitor, an automobile display (for example, an odometer display, etc.), a cockpit controller and / or display, a display of a camera view (for example, a display of a rearview camera in a vehicle), an electronic billboard or sign, a projector, and / or a mobile or fixed terminal.

[0078] For example, the display panel 100 can be an organic light-emitting diode (OLED) display panel, a micro organic light-emitting diode (Micro OLED) display panel, a light emitting diode (LED) display panel, a quantum dot light emitting diode (QLED) display panel, a mini light emitting diode (Mini LED) display panel, a micro light emitting diode (Micro LED) display panel, or a liquid crystal display (LCD) display panel, etc. The embodiments of the present application are described by taking an OLED display panel as an example.

[0079] Referring to Figure 1 and Figure 3The display panel 100 can have a first direction X, a second direction Y, and a third direction Z, and the first direction X, the second direction Y, and the third direction Z are all different. The first direction X and the second direction Y can be any two different directions parallel to the display panel 100, and the third direction Z can be any direction intersecting the plane parallel to the display panel 100. For example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. For example, the first direction X can be the width direction of the display panel 100, the second direction Y can be the length direction of the display panel 100, and the third direction Z can be the thickness direction of the display panel 100. The length, width, and thickness in the embodiments of the present application are only for the convenience of description, and do not mean any limitation on the size. For example, the width can be greater than, equal to, or less than the length. The direction of the display panel 100 can be consistent with the direction of the substrate 110.

[0080] The display panel 100 provided by the embodiments of the present application is described below.

[0081] Referring to Figure 2 , the display panel 100 provided by the embodiments of the present application can include a substrate 110. The substrate 110 can provide support for the remaining film layers subsequently arranged.

[0082] In some embodiments, referring to Figure 1 and Figure 2 , the display panel 100 can include a partition structure 120, and the partition structure 120 can be arranged on one side of the substrate 110. The partition structure 120 can define a plurality of partition openings 124, and the plurality of partition openings 124 can be arranged at intervals.

[0083] In some embodiments, referring to Figure 2 , the display panel 100 includes a light emitting unit 130, and the light emitting unit 130 is located on the side of the substrate 110 facing the partition structure 120. The light emitting unit 130 can be a plurality of light emitting units 130 arranged at intervals, for example, the plurality of light emitting units 130 can be arranged in an array. The light emitting unit 130 and the partition opening 124 can be correspondingly arranged, and the light emitting unit 130 can be at least partially located in the corresponding partition opening 124. The embodiments of the present application take an example that at least part of one light emitting unit 130 can be arranged in one partition opening 124.

[0084] For example, the light emitting unit 130 can include a first electrode 131, that is, the first electrode 131 is a plurality of first electrodes 131 arranged at intervals. The plurality of partition openings 124 and the plurality of first electrodes 131 are correspondingly arranged, and the orthographic projection of the partition opening 124 on the substrate 110 and the orthographic projection of the corresponding first electrode 131 on the substrate 110 overlap each other.

[0085] For example, the first electrode 131 can be formed by forming a first conductive material layer and performing a first patterning process on the first conductive material layer to form a plurality of first electrodes 131. For example, the first patterning process can be a wet etching process.

[0086] The encapsulation part 150 provided by the application embodiments is described below.

[0087] In some embodiments, referring to Figure 2 The display panel 100 includes a first encapsulation layer, and the first encapsulation layer can include a plurality of encapsulation parts 150. The encapsulation part 150 is arranged corresponding to the light emitting unit 130, and the encapsulation part 150 is arranged on a side of the corresponding light emitting unit 130 away from the substrate 110. The encapsulation part 150 is arranged corresponding to the partition opening 124, and the encapsulation part 150 is located in the corresponding partition opening 124. The encapsulation part 150 extends to the side wall of the partition structure 120 and a side of the partition structure 120 away from the substrate 110, so as to better encapsulate the light emitting unit 130.

[0088] For example, the plurality of light emitting units 130 include first light emitting units, second light emitting units, and third light emitting units having different light emitting colors. For example, the first light emitting units, the second light emitting units, and the third light emitting units can be red light emitting units, green light emitting units, and blue light emitting units, respectively. In other examples, the plurality of light emitting units 130 can further include white light emitting units.

[0089] For example, the encapsulation part 150 includes a first extension part located on a side of the partition structure 120 away from the substrate 110. The extension length of the first extension part ranges from 2 μm to 4 μm. Thus, the extension length of the first extension part can be prevented from being too small, so that the distance between the boundary of the blocking part 123 and the boundary of the encapsulation part 150 is large, which is beneficial to reduce the adverse effect of the blocking part 123 on the size measuring instrument in grabbing the boundary of the encapsulation part 150. In addition, the extension length of the first extension part can be prevented from being too large, so that the area of the display panel 100 is not excessively large, which is beneficial to improve the aperture ratio of the display panel 100.

[0090] For example, the extension length of the first extension part is 2 μm, 2.5 μm, 3 μm, 3.5 μm, 4 μm, or any value between 2 μm and 4 μm.

[0091] For example, referring to Figure 3The gap 182 has a size d4 greater than or equal to 2 μm, so that the size d4 of the gap 182 is not too small, and the mutual interference between the two adjacent packaging portions 150 is reduced when the size measuring instrument captures the boundary of the packaging portion 150. In addition, the size d4 of the gap 182 is not too large, and the area of the display panel 100 is not too large, so that the aperture ratio of the display panel 100 is improved.

[0092] For example, the size d4 of the gap 182 is 2 μm, 2.5 μm, 3 μm, or any value greater than 2 μm.

[0093] For example, the material of the packaging portion 150 can include an inorganic insulating material. The packaging portion 150 made of the inorganic material has a good barrier effect on water vapor and oxygen, so that a good packaging effect is achieved.

[0094] For example, the plurality of packaging portions 150 include a first packaging portion, a second packaging portion, and a third packaging portion. The first packaging portion is located on the side of the first light emitting unit away from the substrate 110. The second packaging portion is located on the side of the second light emitting unit away from the substrate 110. The third packaging portion is located on the side of the third light emitting unit away from the substrate 110.

[0095] For example, the first light emitting unit is a blue light emitting unit, and the distance CD1 between the two first edges 151 of the first packaging portion is in the range of 37 μm-40 μm. For example, the distance CD1 between the two first edges 151 of the first packaging portion can be 37 μm, 38 μm, 39 μm, 40 μm, or any value in the range of 37 μm-40 μm. Figure 1

[0096] For example, the second light emitting unit is a green light emitting unit, and the distance CD1 between the two first edges 151 of the second packaging portion is in the range of 30 μm-35 μm. For example, the distance CD1 between the two first edges 151 of the second packaging portion can be 30 μm, 32 μm, 34 μm, 35 μm, or any value in the range of 30 μm-35 μm.

[0097] For example, the third light emitting unit is a red light emitting unit, and the distance CD1 between the two first edges 151 of the third packaging portion is in the range of 32 μm-35 μm. For example, the distance CD1 between the two first edges 151 of the third packaging portion can be 32 μm, 33 μm, 34 μm, 35 μm, or any value in the range of 32 μm-35 μm.

[0098] ​Exemplarily, the process of forming the encapsulation part 150 can include: forming an encapsulation material layer on the side of the partition structure 120 away from the substrate 110, the encapsulation material layer also being in the partition opening 124; performing a fourth patterning process on the encapsulation material layer to remove at least part of the encapsulation material layer on the side of the partition structure 120 away from the substrate 110, and to retain the encapsulation material layer in the partition opening 124, and to form the encapsulation part 150. For example, the fourth patterning process can employ dry etching and / or wet etching.

[0099] The first orthographic projection and the second orthographic projection provided by the embodiments of the present application are described below.

[0100] In some embodiments, referring to Figure 4 , the orthographic projection of the encapsulation part 150 on the substrate 110 is a first orthographic projection, and the orthographic projection of the first electrode 131 on the substrate 110 is a second orthographic projection, in the first orthographic projection and the second orthographic projection arranged correspondingly, the outer contour of the first orthographic projection includes two first edges 151 arranged oppositely along the first direction X, the first edge 151 extends along the second direction Y, the second orthographic projection is located between the two first edges 151, and the second orthographic projection is arranged spaced apart from the first edge 151, so that the adverse effects caused by the mutual overlap of the second orthographic projection and the first edge 151 on the size measuring instrument grabbing the first edge 151 can be alleviated, and the measurement accuracy of the size of the pixel along the first direction X can be improved.

[0101] Exemplarily, the distance CD1 between the two first edges 151 along the first direction X is greater than the size of the rest of the first orthographic projection along the first direction X, and the first edge 151 is a straight edge, so that the difficulty of the size measuring instrument grabbing the first edge 151 can be reduced.

[0102] Exemplarily, the distance d1 between the second orthographic projection and the first edge 151 is greater than or equal to 1 μm, so that the distance between the second orthographic projection and the first edge 151 is relatively large, the boundaries of the encapsulation part 150 on both sides along the first direction X and the boundaries of the first electrode 131 are clearly distinguishable, abnormal phenomena when the size measuring instrument grabs the boundaries of the encapsulation part 150 on both sides along the first direction X can be improved, the size measuring instrument can normally and accurately grab the boundaries of the encapsulation part 150 on both sides along the first direction X, the difficulty of measuring the boundaries of the encapsulation part 150 on both sides along the first direction X can be reduced, the difficulty of measuring the size of the pixel along the first direction X (i.e. CD1) can be further reduced, and the measurement accuracy of the size of the pixel along the first direction X can be improved.

[0103] For example, the distance d1 between the second orthographic projection and the first edge 151 is 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, or any value greater than 1 μm.

[0104] In some embodiments, referring to Figure 4In the corresponding set first orthographic projection and second orthographic projection, the outer contour of the first orthographic projection includes two second edges 152 oppositely arranged along the second direction Y, the second edges 152 extend along the first direction X, the second orthographic projection is located between the two second edges 152, and the second orthographic projection is arranged at a distance from the second edges 152, so as to alleviate the adverse effects of the second orthographic projection overlapping the second edges 152 on the size measuring instrument grabbing the second edges 152, thereby improving the measurement accuracy of the size of the pixel along the second direction Y.

[0105] For example, the distance CD2 between the two second edges 152 along the second direction Y is greater than the size of the rest of the first orthographic projection along the second direction Y, and the second edges 152 are straight edges, thereby reducing the difficulty of the size measuring instrument grabbing the second edges 152.

[0106] For example, the distance d2 between the second orthographic projection and the second edges 152 is greater than or equal to 1 μm, so that the distance between the second orthographic projection and the second edges 152 is large, the boundaries of the packaging part 150 on both sides along the second direction Y are clearly distinguishable from the boundaries of the first electrode 131, the size measuring instrument can normally and accurately grab the boundaries of the packaging part 150 on both sides along the second direction Y, thereby reducing the difficulty of measuring the boundaries of the packaging part 150 on both sides along the second direction Y, and further reducing the difficulty of measuring the size of the pixel along the second direction Y (i.e. CD2), thereby improving the measurement accuracy of the size of the pixel along the second direction Y.

[0107] For example, the distance d2 between the second orthographic projection and the second edges 152 is 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm, or any value greater than 1 μm.

[0108] For example, referring to Figure 4 In the same packaging part 150, the outer contour of the first orthographic projection includes a connecting edge 153, and the first edge 151 and the second edge 152 are connected through the connecting edge 153. For example, the connecting edge 153 is an arc-shaped edge, and the connecting edge 153 is curvedly arranged away from the center of the first orthographic projection. In this way, compared with directly connecting the first edge 151 and the second edge 152 with straight edges, connecting the first edge 151 and the second edge 152 with arc-shaped edges is conducive to increasing the area of the first orthographic projection, i.e. conducive to increasing the coverage area of the packaging part 150, and conducive to improving the packaging effect of the packaging part 150. In addition, compared with directly connecting the first edge 151 and the second edge 152, the extension direction of the connecting edge 153 is different from the first edge 151 and the second edge 152, which can reduce the influence of the connecting edge 153 on the size measuring instrument grabbing the first edge 151 and the second edge 152.

[0109] In some embodiments, the outer contour of the first orthographic projection includes two second edges 152 arranged opposite to each other along the second direction Y, and the connecting edge 153 can be omitted, and the first edge 151 and the second edge 152 are directly connected, so that the shape of the outer contour of the first orthographic projection is relatively simple, which is beneficial to reduce the difficulty of manufacturing the packaging portion 150.

[0110] In the embodiment in which the first edge 151 and the second edge 152 are directly connected, the second edge 152 can be an arc-shaped edge, and the second edge 152 is arranged to be curved away from the center of the first orthographic projection, so as to be beneficial to increase the coverage area of the packaging portion 150 and improve the packaging effect of the packaging portion 150. At this time, since the second edge 152 is an arc-shaped edge, the size measuring instrument is not easy to grab the second edge 152, and the size measuring instrument can grab the first edge 151 but not the second edge 152, so that the influence of the second orthographic projection on the grabbing of the second edge 152 does not need to be considered, and the arrangement position between the second edge 152 and the second orthographic projection is relatively flexible.

[0111] In some embodiments, referring to Figure 4 , the second orthographic projection is located in the first orthographic projection, and the distance between the outer contour of the second orthographic projection and the outer contour of the first orthographic projection is greater than or equal to 1 μm, so as to be beneficial to increase the distance between all boundaries of the packaging portion 150 and all boundaries of the first electrode 131, so that all boundaries of the packaging portion 150 and all boundaries of the first electrode 131 are clearly distinguishable, which is beneficial to realize the measurement of the size of the pixel in each direction by the size measuring instrument.

[0112] For example, the distance between the outer contour of the second orthographic projection and the outer contour of the first orthographic projection is 1 μm, 1.5 μm, 2 μm, 2.5 μm, 3 μm or any value greater than 1 μm.

[0113] It can be understood that the embodiments of the present application are mainly illustrated by taking the second orthographic projection located between the two first edges 151 as an example, and the second orthographic projection is arranged to be spaced apart from the first edge 151, so that the first edge 151 and the third edge 1313 are arranged to be spaced apart, so as to alleviate the adverse effects caused by the mutual overlap between the second orthographic projection and the first edge 151 on the grabbing of the first edge 151 by the size measuring instrument. In some other embodiments, the outer contour of the second orthographic projection includes two third edges 1313 arranged opposite to each other along the first direction X, Figure 5), the third edge 1313 extends along the second direction Y. In the corresponding arranged first orthographic projection and the second orthographic projection, the first orthographic projection is located between the two third edges 1313, and the first orthographic projection is arranged apart from the third edge 1313, so that the first edge 151 and the third edge 1313 are arranged apart, thereby the adverse effect on the size measuring instrument grabbing the first edge 151 due to the first edge 151 and the third edge 1313 overlapping each other can be alleviated. Alternatively, in the corresponding arranged first orthographic projection and the second orthographic projection, one of the two first edges 151 is located between the two third edges 1313, and the other first edge 151 is located outside the two third edges 1313, so that the first edge 151 and the third edge 1313 are arranged apart, thereby the adverse effect on the size measuring instrument grabbing the first edge 151 due to the first edge 151 and the third edge 1313 overlapping each other can be alleviated.

[0114] The insulating layer 160 and the conductive member 183 provided in the embodiments of the present application are described below.

[0115] In some embodiments, referring to Figure 3 , the display panel 100 further includes an insulating layer 160, the insulating layer 160 is arranged between the substrate 110 and the first electrode 131, and the insulating layer 160 encloses to form a plurality of vias 161. The display panel 100 further includes a conductive member 183, the conductive member 183 is located between the substrate 110 and the insulating layer 160, and the via 161 exposes the conductive member 183. The via 161 is arranged corresponding to the first electrode 131, and the first electrode 131 is connected with the conductive member 183 through the corresponding via 161.

[0116] The connecting member 140 provided in the embodiments of the present application is described below.

[0117] In some embodiments, referring to Figure 3 and Figure 4 , the orthographic projection of the via 161 on the substrate 110 is at least partially located outside the corresponding first orthographic projection, the first electrode 131 is provided with a connecting member 140, the connecting member 140 extends into the corresponding via 161, and the connecting member 140 is electrically connected with the conductive member 183 through the via 161. That is, the first electrode 131 realizes electrical connection with the conductive member 183 through the connecting member 140 and the via 161. In this way, by arranging the connecting member 140, the flexibility of the setting position of the via 161 can be improved.

[0118] Exemplarily, referring to Figure 4In the first electrode 131 and the connecting piece 140 corresponding to the setting, the extension length of the outer contour of the first electrode 131 is greater than the extension length d5 of the connecting piece 140 along the circumference of the first electrode 131, so that the extension length d5 of the connecting piece 140 along the circumference of the first electrode 131 is small, which is beneficial to reduce the adverse effects of the connecting piece 140 on the boundary of the packaging portion 150. In addition, the first electrode 131 is connected to the conductive piece 183 through the connecting piece 140 with small size, which is beneficial to improve the wiring density of the display panel 100.

[0119] For example, referring to Figure 4 , the orthographic projection of the connecting piece 140 on the substrate 110 is a third orthographic projection, the third orthographic projection overlaps with part of the outer contour of the first orthographic projection, so that the third orthographic projection does not overlap with another part of the outer contour of the first orthographic projection, thereby facilitating the size measuring instrument to grasp the boundary of the packaging portion 150 corresponding to the non-overlapping first orthographic projection, so as to facilitate the determination of the size of the pixel.

[0120] For example, the connecting piece 140 and the corresponding first electrode 131 are an integral structure, thereby simplifying the preparation process of the connecting piece 140 and the corresponding first electrode 131, and improving the connection stability between the connecting piece 140 and the corresponding first electrode 131.

[0121] For example, referring to Figure 4 and Figure 9 , the straight side (for example, the first side 151) of the outer contour of the first orthographic projection includes a first end point 1541 and a second end point 1542 arranged oppositely, and a midpoint 1543 between the first end point 1541 and the second end point 1542. The line segment between the first end point 1541 and the midpoint 1543 of the straight side passes through the third orthographic projection, and the distance between the third orthographic projection and the midpoint 1543 is greater than the distance between the third orthographic projection and the first end point 1541, so that the third orthographic projection is arranged close to the first end point 1541 of the straight side, thereby facilitating to reduce the adverse effects of the connecting piece 140 on the boundary of the packaging portion 150 corresponding to the straight side, reducing the difficulty of measuring the size of the pixel, and improving the measurement accuracy of the size of the pixel.

[0122] For example, referring to Figure 4 , the straight side of the outer contour of the first orthographic projection can be the first side 151, the line segment between the first end point 1541 and the midpoint 1543 of the first side 151 passes through the third orthographic projection, and the distance between the third orthographic projection and the midpoint 1543 of the first side 151 is greater than the distance between the third orthographic projection and the first end point 1541 of the first side 151. Alternatively, referring to Figure 5The straight edge of the outer contour of the first orthographic projection can be the second edge 152, the second edge 152 is located on the line segment between the first end point 1541 and the midpoint 1543 of the second edge 152, the third orthographic projection is located on the line segment, and the distance between the third orthographic projection and the midpoint 1543 of the second edge 152 is greater than the distance between the third orthographic projection and the first end point 1541 of the second edge 152.

[0123] In some embodiments, the arc-shaped edge of the outer contour of the first orthographic projection extends into the third orthographic projection, so that the third orthographic projection is arranged close to the arc-shaped edge, thereby facilitating reduction of the adverse effects of the boundary gripping of the straight edge of the outer contour of the first orthographic projection on the edge of the packaging portion 150 corresponding to the straight edge, reducing the difficulty of measuring the size of the pixel, and improving the measurement accuracy of the size of the pixel.

[0124] For example, the arc-shaped edge of the outer contour of the first orthographic projection passes through the third orthographic projection, that is, the straight edge of the outer contour of the first orthographic projection does not overlap the third orthographic projection, and the arc-shaped edge of the outer contour of the first orthographic projection overlaps the third orthographic projection, thereby better reducing the adverse effects of the boundary gripping of the straight edge of the outer contour of the first orthographic projection on the edge of the packaging portion 150 corresponding to the straight edge, better reducing the difficulty of measuring the size of the pixel, and better improving the measurement accuracy of the size of the pixel.

[0125] In the embodiment in which the first edge 151 is a straight edge and the second edge 152 is an arc-shaped edge, the first edge 151 does not overlap the third orthographic projection, and the second edge 152 overlaps the third orthographic projection. Alternatively, referring to Figure 6 In the embodiment in which the first edge 151 and the second edge 152 are straight edges and the connecting edge 153 is an arc-shaped edge, the first edge 151 and the second edge 152 do not overlap the third orthographic projection, and the connecting edge 153 overlaps the third orthographic projection.

[0126] In other embodiments, referring to Figure 7 and Figure 8 The orthographic projection of the via 161 on the substrate 110 is located in the first orthographic projection, so that the connecting member 140 is not required to connect the conductive member 183 and the first electrode 131, and the adverse effects of the connecting member 140 on the determination of the pixel size can be avoided. At this time, the first electrode 131 can extend into the corresponding via 161, and the first electrode 131 is directly connected with the conductive member 183.

[0127] The pixel definition layer 170 provided by the embodiments of the present application is described below.

[0128] In some embodiments, referring to Figure 2The display panel 100 may include a pixel defining layer 170, which may be disposed between the partition structure 120 and the substrate 110. The pixel defining layer 170 defines a plurality of pixel openings 171, which are correspondingly connected to the partition openings 124. The orthographic projection of the pixel openings 171 onto the substrate 110 may lie within the orthographic projection of the partition openings 124 onto the substrate 110. The light-emitting unit 130 may be at least partially located within the pixel openings 171. Thus, by providing the pixel defining layer 170, it is convenient to provide the light-emitting unit 130 on the substrate 110.

[0129] For example, the pixel defining layer 170 is located between the partition structure 120 and the first electrode 131, and the pixel opening 171 exposes the corresponding first electrode 131. A portion of the light-emitting functional element 133 is disposed in the corresponding pixel opening 171 and extends from the corresponding pixel opening 171 to the corresponding partition opening 124.

[0130] For example, see Figure 4 The orthographic projection of the pixel opening 171 on the substrate 110 is the fourth orthographic projection, which is located within the second orthographic projection. This results in a larger distance between the boundary of the pixel opening 171 and the boundary of the encapsulation portion 150, which helps to reduce the adverse effects of the pixel limiting layer 170 on the boundary of the encapsulation portion 150, reduce the difficulty of measuring the pixel size, and improve the accuracy of pixel size measurement.

[0131] For example, the distance d3 between the outer contour of the second orthographic projection and the outer contour of the fourth orthographic projection ( Figure 4 The range of the pixel opening is 2μm-4μm, which can avoid the distance d3 between the outer contour of the second orthographic projection and the outer contour of the fourth orthographic projection being too small. This helps to reduce the adverse effect of the pixel limiting layer 170 on the boundary gripping of the encapsulation part 150, and can also improve the coverage stability of the pixel limiting layer 170 on the edge of the first electrode 131. In addition, it can avoid the distance d3 between the outer contour of the second orthographic projection and the outer contour of the fourth orthographic projection being too large, which helps to increase the size of the pixel opening 171, thereby increasing the aperture ratio of the display panel 100.

[0132] For example, the outer contour of the fourth orthographic projection can be the orthographic projection of the end of the pixel opening 171 facing away from the substrate 110 onto the substrate 110.

[0133] For example, the distance d3 between the outer contour of the second orthographic projection and the outer contour of the fourth orthographic projection is 2μm, 2.5μm, 3μm, 3.5μm, 4μm or any value between 2μm and 4μm.

[0134] For example, the process of forming the pixel defining layer 170 may include forming a pixel defining material layer on the side of the first electrode 131 facing away from the substrate 110, performing a second patterning process on the pixel defining material layer to form a plurality of pixel openings 171, and retaining the pixel defining material layer to form the pixel defining layer 170. For example, the second patterning process may employ dry etching.

[0135] In some embodiments, the pixel limiting layer 170 may not be provided on the substrate 110, which can help simplify the structure of the display panel 100, reduce the manufacturing cost of the display panel 100, and help make the display panel 100 thinner and lighter.

[0136] The partition structure 120 provided in the embodiments of this application will be further described below.

[0137] In some embodiments, the partition structure 120 may refer to an undercut structure that is larger at the top and smaller at the bottom, capable of separating adjacent light-emitting functional elements 133. The partition structure 120 may be a structure formed by a single film layer or a structure formed by stacking multiple film layers.

[0138] For example, the cross-sectional shape of the partition structure 120 can be an inverted trapezoid with a larger top and a smaller bottom, a "T" shape, or an "I" shape, etc.

[0139] In some embodiments, see Figure 2 The partition structure 120 may include a first isolation portion 121 and a blocking portion 123. The first isolation portion 121 is located on the side of the blocking portion 123 facing the substrate 110. The orthographic projection of the first isolation portion 121 on the substrate 110 is located within the orthographic projection of the blocking portion 123 on the substrate 110, thereby making the partition structure 120 form an undercut structure that is "larger at the top and smaller at the bottom", that is, the partition structure 120 has an "eaves". In this way, during the formation of the light-emitting functional element 133, the partition structure 120 can separate two adjacent light-emitting functional elements 133.

[0140] In some embodiments, see Figure 2 The partition structure 120 may include a second isolation portion 122, which may be located on the side of the first isolation portion 121 opposite to the blocking portion 123. The orthographic projection of the first isolation portion 121 on the substrate 110 may be located within the orthographic projection of the second isolation portion 122 on the substrate 110. Thus, in embodiments where the partition structure 120 is made of a conductive material, by providing the stacked first isolation portion 121, second isolation portion 122, and blocking portion 123, the resistance of the partition structure 120 can be reduced, thereby reducing the power consumption of the display panel 100.

[0141] For example, the material of at least one of the first isolation portion 121, the second isolation portion 122 and the blocking portion 123 can be a conductive material. The material of at least one of the first isolation portion 121, the second isolation portion 122 and the blocking portion 123 can include any one or more of titanium, silver, copper, aluminum, molybdenum and the like metal, or an alloy, or a conductive oxide such as Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), zinc oxide (ZnO), aluminum zinc oxide (AZO), zinc oxide, titanium tantalum oxide, tin oxide, cadmium oxide, indium oxide. In other examples, the material of at least one of the first isolation portion 121, the second isolation portion 122 and the blocking portion 123 can be an insulating material, which is not limited in the embodiments of the present application.

[0142] For example, the material of the blocking portion 123 can include at least one of titanium and molybdenum.

[0143] For example, the material of the first isolation portion 121 can include at least one of aluminum, copper and silver.

[0144] For example, the material of the second isolation portion 122 can include at least one of titanium and molybdenum.

[0145] In the embodiment in which the material of at least one of the first isolation portion 121, the second isolation portion 122 and the blocking portion 123 is a conductive material, the second electrode 132 can be electrically connected with the partition structure 120. In this way, the second electrodes 132 located in the partition openings 124 can be connected as a whole through the partition structure 120, and the second electrode 132 can be electrically connected with the second power supply line through the partition structure 120, so as to apply a power supply voltage to the second electrode 132, thereby optimizing the wiring arrangement of the display panel 100.

[0146] In the embodiment in which the material of the first isolation portion 121 is a conductive material, the second electrode 132 can be electrically connected with the first isolation portion 121.

[0147] In the embodiment in which the material of the second isolation portion 122 is a conductive material, the second electrode 132 can be electrically connected with the second isolation portion 122.

[0148] In the embodiment in which the materials of the first isolation portion 121 and the second isolation portion 122 are both conductive materials, the second electrode 132 can be electrically connected with at least one of the first isolation portion 121 and the second isolation portion 122, for example, the second electrode 132 is connected with both the first isolation portion 121 and the second isolation portion 122, thereby improving the connection stability of the second electrode 132 and the partition structure 120.

[0149] Exemplarily, the process of forming the partition structure 120 can include forming a partition material layer on the side of the pixel definition layer 170 away from the substrate 110, performing a third patterning process on the partition material layer to form a plurality of partition openings 124, and the remaining partition material layer forms the partition structure 120. For example, the third patterning process can employ dry etching and / or wet etching.

[0150] The composition, preparation, etc. of the partition structure 120 mentioned in the embodiments of the present application are described in the patents CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 100935, PCT / CN2024 / 102785, PCT / CN2024 / 099419, PCT / CN2024 / 099072, CN116685174A, for reference.

[0151] The following further describes the light emitting unit 130 provided by the embodiments of the present application.

[0152] In some embodiments, referring to Figure 2 , the light emitting unit 130 can include a first electrode 131, a light emitting functional member 133, and a second electrode 132, which are sequentially stacked in the direction away from the substrate 110.

[0153] For example, part of the first electrode 131 can be covered by the pixel definition layer 170, and another part of the first electrode 131 can be exposed by the corresponding pixel opening 171.

[0155] Exemplarily, the first electrode 131 can be electrically connected with the pixel driving circuit, and the pixel driving circuit can be electrically connected with the first power line. The second electrode 132 can be electrically connected with the second power line. One of the first power line and the second power line is used for transmitting a high voltage, and the other is used for transmitting a low voltage. For example, the first power line is used for transmitting a high voltage, and the second power line is used for transmitting a low voltage.

[0156] The light emitting functional member 133 can include, for example, an emission layer (EML). In addition, the light emitting functional member 133 can further include at least one of a hole injection layer (HIL), a hole transport layer (HTL), an electron injection layer (EIL), an electron transport layer (ETL), a hole block layer (HBL), and an electron block layer (EBL).
