Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] Organic Light Emitting Diode (OLED) display technology is considered the most promising new flat-panel display technology for the next generation. Compared with liquid crystal display technology, OLED display technology has advantages such as low energy consumption, low cost, self-luminescence, wide viewing angle, and fast response speed.

[0003] Traditional display panel manufacturing typically uses a fine metal mask (FMM) to pattern luminescent pixels. FMM technology is mature and boasts extensive mass production experience. However, it also suffers from limitations such as limited precision, high development costs, and long development cycles. FMM-free technology eliminates the limitations of traditional OLED processes on display size, resolution, and other performance characteristics, offering the advantages of high performance, full-area scalability, and agile delivery.

DETAILED DESCRIPTION

[0076] To facilitate understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings.

[0077] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0078] Display panels manufactured using fine metal mask-free technology offer high PPI and allow for smaller subpixels. However, smaller subpixels can lead to display issues, such as color unevenness at low grayscale levels. The inventors have discovered that this problem is caused by the high electrical connection impedance between the subpixel cathode and the isolation structure.

[0079] In view of the above-mentioned problems, the display panel and display device provided in the embodiments of the present application respectively construct accommodation spaces on both sides of the first projected pattern along the second direction. This allows not only first overlapping edges to be provided on both sides of the first projected pattern in the first direction, but also second overlapping edges to be provided on both sides of the accommodation space in the first direction. Thus, when evaporating the second electrode, the evaporation source can be scanned along the first direction, so that the orthographic projection of the second electrode overlaps the first overlapping edge and the second overlapping edge. In other words, this facilitates extending the second electrode to the sidewalls of the isolation structure corresponding to the first overlapping edge and the second overlapping edge, thereby increasing the overlapping area between the second electrode and the isolation structure, reducing the overlapping impedance, and improving the display effect.

[0080] First, refer to Figures 1-8 As shown, an embodiment of the present application provides a display panel 10, which may be an organic light emitting diode display panel 10 (Organic Light Emitting Diode, referred to as OLED) or a quantum dot electroluminescent display panel 10 (Quantum Dot Light Emitting Diodes, referred to as QLED).

[0081] The display panel 10 includes an array substrate 11, an isolation structure 12, and a plurality of light-emitting devices 13. The array substrate 11 includes a plurality of scan lines 11a arranged at intervals along a first direction X. The isolation structure 12 is located on one side of the array substrate 11 and is provided with a plurality of opening groups 12a. The opening groups 12a include at least one first isolation opening 12a1, at least one second isolation opening 12a2, and at least one third isolation opening 12a3. Multiple light-emitting devices 13 are located on one side of the array substrate 11. These light-emitting devices 13 include multiple first light-emitting devices 13a, multiple second light-emitting devices 13b, and multiple third light-emitting devices 13c. The first light-emitting devices 13a are positioned corresponding to the first isolation openings 12a1, the second light-emitting devices 13b are positioned corresponding to the second isolation openings 12a2, and the third light-emitting devices 13c are positioned corresponding to the third isolation openings 12a3. Exemplarily, the first light-emitting devices 13a are positioned in a one-to-one correspondence with the first isolation openings 12a1, the second light-emitting devices 13b are positioned in a one-to-one correspondence with the second isolation openings 12a2, and the third light-emitting devices 13c are positioned in a one-to-one correspondence with the third isolation openings 12a3. At least a portion of the first light-emitting device 13a is positioned within the corresponding first isolation opening 12a1, at least a portion of the second light-emitting device 13b is positioned within the corresponding second isolation opening 12a2, and at least a portion of the third light-emitting device 13c is positioned within the corresponding third isolation opening 12a3. It will be understood that, from a planar perspective, the size and shape of the isolation openings match the size and shape of the light-emitting devices 13.

[0082] The first light-emitting device 13a, the second light-emitting device 13b, and the third light-emitting device 13c are each configured to emit light of a different color. Each light-emitting device 13 includes a first electrode 131, a light-emitting structure 132, and a second electrode 133, which are stacked. The second electrode 133 is electrically connected to the isolation structure 12. The first electrode 131 can be an anode, and the second electrode 133 can be a cathode.

[0083] The orthographic projection of one end of the first isolation opening 12a1 close to the array substrate 11 on the array substrate 11 is a first projection figure S1; the first projection figure S1 is respectively constructed with an accommodating space S1a on both sides along the second direction Y, the first projection figure S1 includes a first overlapping edge S11 located on both sides of itself in the first direction X, and includes a second overlapping edge S12 located on both sides of the accommodating space S1a along the first direction X, the orthographic projection of the second electrode 133 of the first light-emitting device 13a on the array substrate 11 overlaps with both the first overlapping edge S11 and the second overlapping edge S12; the first direction X and the second direction Y intersect.

[0084] like Figure 2 and Figure 4 As shown, the first isolation opening 12a1 passes through the isolation structure 12 along the vertical direction (the thickness direction of the array substrate 11), and the end of the first isolation opening 12a1 close to the array substrate 11 is the bottom end of the first isolation opening 12a1. In other words, the first projection figure S1 can be considered as: the positive projection of the bottom end of the side wall of the isolation structure 12 close to the first isolation opening 12a1 on the array substrate 11.

[0085] In one example, if Figure 2 As shown, the isolation structure 12 includes a base 123, an isolator 122, and a blocking portion 121 stacked in a direction away from the array substrate 11. The bottom end of the side wall of the base 123 close to the first isolation opening 12a1 is projected onto the array substrate 11 as a first projection pattern S1. Specifically, the base 123 can be made of molybdenum (Mo), the isolator 122 can be made of aluminum (Al), and the blocking portion 121 can be made of titanium (Ti). In another example, Figure 4 As shown, the isolation structure 12 includes an isolator 122 and a blocking portion 121 stacked in a direction away from the array substrate 11. The bottom end of the sidewall of the isolator 122 near the first isolation opening 12a1 is projected onto the array substrate 11 as a first projection pattern S1. Specifically, the isolator 122 can be made of aluminum (Al), and the blocking portion 121 can be made of titanium (Ti). The definitions of the second projection pattern S2 and the third projection pattern S3 below are the same as those of the first projection pattern S1 and are not further described here.

[0086] In the embodiment of the present application, by constructing accommodating spaces S1a on both sides of the first projection pattern S1 along the second direction Y, not only can first overlapping edges S11 be provided on both sides of the first projection pattern S1 along the first direction X, but second overlapping edges S12 can also be provided on both sides of the accommodating space S1a along the first direction X. Thus, when evaporating the second electrode 133, the evaporation source can be scanned along the first direction X, so that the orthographic projection of the second electrode 133 overlaps the first overlapping edges S11 and the second overlapping edges S12. In other words, this facilitates extending the second electrode 133 onto the sidewalls of the isolation structure 12 corresponding to the first overlapping edges S11 and the second overlapping edges S12, thereby increasing the overlapping area between the second electrode 133 and the isolation structure 12, reducing the overlapping impedance, and improving the display effect.

[0087] In one embodiment, Figure 5-Figure 8 As shown, the orthographic projection of the end of the second isolation opening 12a2 closest to the array substrate 11 on the array substrate 11 is a second projection pattern S2, and the orthographic projection of the end of the third isolation opening 12a3 closest to the array substrate 11 on the array substrate 11 is a third projection pattern S3. In the same opening group 12a, at least two of all the second projection patterns S2 and all the third projection patterns S3 respectively extend into the two accommodation spaces S1a of the same first projection pattern S1. In one example, one second projection pattern S2 and one third projection pattern S3 respectively extend into the two accommodation spaces S1a of the same first projection pattern S1. In another example, two second projection patterns S2 respectively extend into the two accommodation spaces S1a of the same first projection pattern S1. In yet another example, four second projection patterns S2 are grouped in pairs, and the two groups respectively extend into the two accommodation spaces S1a of the same first projection pattern S1.

[0088] Furthermore, the second projection figure S2 includes a third overlap edge S21 located on both sides of its own first direction X, and the orthographic projection of the second electrode 133 of the second light-emitting device 13b on the array substrate 11 overlaps with the third overlap edge S21. The third projection figure S3 includes a fourth overlap edge S31 located on both sides of its own first direction X, and the orthographic projection of the second electrode 133 of the third light-emitting device 13c on the array substrate 11 overlaps with the fourth overlap edge S31.

[0089] Thus, when evaporating the second electrode 133 of the second light-emitting device 13b, the evaporation source is scanned along the first direction X, so that the orthographic projection of the second electrode 133 of the second light-emitting device 13b overlaps the third overlapping edge S21. When evaporating the second electrode 133 of the third light-emitting device 13c, the evaporation source is scanned along the first direction X, so that the orthographic projection of the second electrode 133 of the third light-emitting device 13c overlaps the fourth overlapping edge S31. This increases the overlapping area between the second electrode 133 and the isolation structure 12, reduces the overlapping impedance, and improves the display effect.

[0090] In one embodiment, the plurality of opening groups 12a are arranged in a plurality of rows along the first direction X and in a plurality of columns along the second direction Y. This helps to arrange the first light-emitting devices 13a, the second light-emitting devices 13b, and the third light-emitting devices 13c more regularly and in accordance with a certain arrangement rule, thereby improving the display effect.

[0091] In one embodiment, the first direction X and the second direction Y are perpendicular.

[0092] In one embodiment, Figure 5 As shown, within the same opening group 12a, at least one second projection pattern S2 extends into the accommodation space S1a on one side of the first projection pattern S1 along the second direction Y, and at least one third projection pattern S3 extends into the accommodation space S1a on the other side of the first projection pattern S1 along the second direction Y. Thus, in the plan view, this is equivalent to interlocking the second isolation opening 12a2 with the first isolation opening 12a1, and interlocking the third isolation opening 12a3 with the first isolation opening 12a1. Given limited space in the second direction Y, this facilitates increasing the dimensions of the first isolation opening 12a1, the second isolation opening 12a2, and the third isolation opening 12a3 along the second direction Y, thereby facilitating increases in the lengths of the first overlapping edge S11, the third overlapping edge S21, and the fourth overlapping edge S31. This is beneficial to increasing the overlap length between the second electrode 133 of each light-emitting device 13 (such as the first light-emitting device 13a, the second light-emitting device 13b and the third light-emitting device 13c) and the isolation structure 12, thereby increasing the overlap area between the second electrode 133 and the isolation structure 12, reducing the overlap impedance and improving the display effect.

[0093] In one embodiment, within the same opening group 12a, at least one second projection pattern S2 extends into the accommodation space S1a on one side of the first projection pattern S1 along the second direction Y, and a third projection pattern S3 extends into the accommodation space S1a on the other side of the first projection pattern S1 along the second direction Y. This helps increase the overlap length between the second electrode 133 of each light-emitting device 13 (such as the first light-emitting device 13a, the second light-emitting device 13b, and the third light-emitting device 13c) and the isolation structure 12, thereby increasing the overlap area between the second electrode 133 and the isolation structure 12, reducing the overlap impedance, and improving the display effect.

[0094] In one embodiment, Figure 3 As shown, the opening group 12a includes a first isolated opening 12a1, a second isolated opening 12a2, and a third isolated opening 12a3. Within the same opening group 12a, the second isolated opening 12a2 and the third isolated opening 12a3 are located on either side of the first isolated opening 12a1 along the second direction Y. The second projection pattern S2 extends into the accommodation space S1a on one side of the first projection pattern S1 along the second direction Y, and the third projection pattern S3 extends into the accommodation space S1a on the other side of the first projection pattern S1 along the second direction Y. This is equivalent to arranging the first light-emitting device 13a, the second light-emitting device 13b, and the third light-emitting device 13c in sequence along the second direction Y, achieving a Real RGB arrangement and improving display effects.

[0095] In one embodiment, Figure 7 As shown, a first protrusion S2a is formed on one side of the second projection pattern S2 along the second direction Y, and a portion of the first protrusion S2a extends into an accommodation space S1a of the first projection pattern S1, so that the first protrusion S2a and the accommodation space S1a achieve a "concave-convex" fit.

[0096] In one embodiment, the second projection pattern S2 further includes a first main portion S2b, and the first protrusion S2a is located on one side of the first main portion S2b along the second direction Y. Each third overlapping edge S21 includes a first sub-overlapping edge S211 and a second sub-overlapping edge S212, wherein the first sub-overlapping edges S211 of the two third overlapping edges S21 are respectively located on both sides of the first main portion S2b along the first direction X, and the second sub-overlapping edges S212 of the two third overlapping edges S21 are respectively located on both sides of the first protrusion S2a along the first direction X.

[0097] In this way, the second electrode 133 of the second light-emitting device 13b not only overlaps with the isolation structure 12 corresponding to the first sub-overlap edge S211, but also overlaps with the isolation structure 12 corresponding to the second sub-overlap edge S212, and the total length of the third overlap edge S21 will not be reduced due to the setting of the first protrusion S2a, which is beneficial to ensuring the overlap area of the second electrode 133 of the second light-emitting device 13b.

[0098] In one embodiment, the first sub-overlapping edge S211 is perpendicular to the first direction X. Thus, when evaporating the second electrode 133 , the evaporation source is scanned along the first direction X. The second electrode 133 has the highest overlapping height, the largest overlapping area, and the smallest overlapping impedance on the isolation structure 12 corresponding to the first sub-overlapping edge S211 , thereby improving the display effect.

[0099] In one embodiment, the second sub-overlapping edge S212 is perpendicular to the first direction X. Thus, when evaporating the second electrode 133 , the evaporation source is scanned along the first direction X. The second electrode 133 has the highest overlapping height, the largest overlapping area, and the smallest overlapping impedance on the isolation structure 12 corresponding to the second sub-overlapping edge S212 , thereby improving the display effect.

[0100] In one embodiment, Figure 7 As shown, the second projection figure S2 also includes a first side S22, a second side S23 and two third sides S24; the first side S22 is located on the side of the first main body S2b away from the first protrusion S2a, and connects the two first sub-overlapping edges S211; the second side S23 is located on the side of the first protrusion S2a away from the first main body S2b, and connects the two second sub-overlapping edges S212; the two third sides S24 are located on the side of the first main body S2b close to the first protrusion S2a, and each third side S24 connects a first sub-overlapping edge S211 and a second sub-overlapping edge S212.

[0101] In one embodiment, the first side S22 , the second side S23 , and the third side S24 are all parallel to the first direction X.

[0102] In one embodiment, the second projection pattern S2 is in a T-shape.

[0103] In one embodiment, Figure 9 、 Figure 10 and Figure 11As shown, the opening group 12a includes a first isolated opening 12a1, two second isolated openings 12a2, and a third isolated opening 12a3. Within the same opening group 12a, the two second isolated openings 12a2 are located on one side of the first isolated opening 12a1 along the second direction Y, and the two second projection patterns S2 extend into the accommodation space S1a on the side of the first projection pattern S1 along the second direction Y. A third isolated opening 12a3 is located on the other side of the first isolated opening 12a1 along the second direction Y, and the third projection pattern S3 extends into the accommodation space S1a on the side of the first projection pattern S1 along the second direction Y. This is equivalent to splitting a complete second light-emitting device 13b into two second light-emitting devices 13b. The second isolated opening 12a2 corresponding to each second light-emitting device 13b has two third overlapping edges S21, thereby increasing the overlapping length of the second light-emitting device 13b, reducing the overlapping impedance, and improving the display effect. It should be noted that the two second light-emitting devices 13b are connected to the same pixel circuit to achieve simultaneous illumination and extinguishing.

[0104] In one embodiment, Figure 3 and Figure 9 In the illustrated arrangement, the wavelength of light emitted by the first light-emitting device 13a is between 440nm and 480nm, meaning that the first light-emitting device 13a is a blue light-emitting device 13. The wavelength of light emitted by the second light-emitting device 13b is between 505nm and 545nm, meaning that the second light-emitting device 13b is a green light-emitting device 13. The wavelength of light emitted by the third light-emitting device 13c is between 600nm and 650nm, meaning that the third light-emitting device 13c is a red light-emitting device 13. This achieves a Real RGB arrangement, resulting in a better display effect.

[0105] In one embodiment, the area of the third projection pattern S3 and the area of the second projection pattern S2 are both smaller than the area of the first projection pattern S1. In other words, the projection area of the third isolation opening 12a3 and the projection area of the second isolation opening 12a2 are both smaller than the projection area of the first isolation opening 12a1.

[0106] In this way, it is beneficial to match the area of the first light-emitting device 13 a with the lifetime ranking of the first light-emitting device 13 a (the ranking among the three devices), thereby maximizing the service life of the display panel 1010 .

[0107] In one embodiment, the area of the third projection pattern S3 is larger than the area of the second projection pattern S2. In other words, the projection area of the third isolation opening 12a3 is larger than the projection area of the second isolation opening 12a2.

[0108] In this way, it is beneficial to match the area of the third light-emitting device 13c and the life ranking of the third light-emitting device 13c (the ranking among the three devices), and to match the area of the second light-emitting device 13b and the life ranking of the second light-emitting device 13b (the ranking among the three devices), thereby maximizing the service life of the display panel 10.

[0109] In one embodiment, referring to Figure 12-15 As shown, the opening group 12a includes a first isolated opening 12a1, at least one second isolated opening 12a2, and two third isolated openings 12a3. Within the same opening group 12a, one third projection pattern S3 extends into the accommodation space S1a on one side of the first projection pattern S1 along the second direction Y, and another third projection pattern S3 extends into the accommodation space S1a on the other side of the first projection pattern S1 along the second direction Y.

[0110] In this way, it is equivalent to arranging two third light-emitting devices 13c on both sides of the first light-emitting device 13a along the second direction Y, and making the third light-emitting device 13c and the first light-emitting device 13a "concave and convex" match each other, which is conducive to realizing Real RGB arrangement and achieving better display effect.

[0111] In one embodiment, Figure 12 and Figure 13 As shown, the opening group 12a includes two second isolation openings 12a2. In the same opening group 12a, the two second isolation openings 12a2 are located on the side of a third isolation opening 12a3 away from the first isolation opening 12a1, and the two second isolation openings 12a2 are arranged at intervals along the first direction X. In this way, it is equivalent to splitting a complete second light-emitting device 13b into two second light-emitting devices 13b. The second isolation opening 12a2 corresponding to each second light-emitting device 13b has two third overlapping edges S21, thereby increasing the overlapping length of the second light-emitting device 13b, reducing the overlapping impedance, and improving the display effect. It should be noted that the two second light-emitting devices 13b are connected to the same pixel circuit to achieve simultaneous light emission and simultaneous extinguishing.

[0112] In one embodiment, Figure 14 and Figure 15 As shown, the opening group 12a includes a second isolated opening 12a2. Within the same opening group 12a, the second isolated opening 12a2 is located to one side of the first isolated opening 12a1 along the first direction X. This facilitates the implementation of a Real RGB arrangement and also helps to lengthen the second projection pattern S2 along the second direction Y, thereby increasing the overlap length of the second light-emitting device 13b, reducing the overlap impedance, and improving the display effect.

[0113] In one embodiment, the dimension of the second projection pattern S2 along the second direction Y is greater than the dimension of the first projection pattern S1 along the second direction Y. This facilitates making the dimension of the second projection pattern S2 along the second direction Y longer, thereby increasing the overlap length of the second light-emitting device 13b, reducing the overlap impedance, and improving the display effect.

[0114] In one embodiment, the dimension of the second projection pattern S2 along the second direction Y is greater than the dimension of the third projection pattern S3 along the second direction Y. This helps to make the dimension of the second projection pattern S2 along the second direction Y longer, thereby increasing the overlap length of the second light-emitting device 13b, reducing the overlap impedance, and improving the display effect.

[0115] In one embodiment, Figure 11 As shown, the second projection figure S2 further includes two fourth sides S25 located on both sides of the second direction Y thereof, and each fourth side S25 is connected to the third overlapping sides S21 on both sides of the second projection figure S2.

[0116] In one embodiment, the third overlapping edge S21 is perpendicular to the first direction X. Thus, when evaporating the second electrode 133 , the evaporation source is scanned along the first direction X. The second electrode 133 has the highest overlapping height, the largest overlapping area, and the smallest overlapping impedance on the isolation structure 12 corresponding to the third overlapping edge S21 , thereby improving the display effect.

[0117] In one embodiment, the fourth side S25 is parallel to the first direction X.

[0118] In one embodiment, the second projection pattern S2 is in the shape of a rectangle.

[0119] In one embodiment, Figure 12 and Figure 14 In this arrangement, the wavelength of light emitted by the first light-emitting device 13a is between 600nm and 650nm, that is, the first light-emitting device 13a is a red light-emitting device 13. The wavelength of light emitted by the second light-emitting device 13b is between 505nm and 545nm, that is, the second light-emitting device 13b is a green light-emitting device 13. The wavelength of light emitted by the third light-emitting device 13c is between 440nm and 480nm, that is, the third light-emitting device 13c is a blue light-emitting device 13. This achieves a Real RGB arrangement, resulting in a better display effect.

[0120] In one embodiment, the area of the first projection pattern S1 and the area of the second projection pattern S2 are both smaller than the area of the third projection pattern S3. In other words, the projection area of the first isolation opening 12a1 and the projection area of the second isolation opening 12a2 are both smaller than the projection area of the third isolation opening 12a3.

[0121] In this way, it is beneficial to match the area of the third light-emitting device 13 c and the lifetime ranking of the third light-emitting device 13 c (the ranking among the three devices), thereby maximizing the service life of the display panel 1010 .

[0122] In one embodiment, the area of the first projection pattern S1 is larger than the area of the second projection pattern S2. In other words, the projection area of the first isolation opening 12a1 is larger than the projection area of the second isolation opening 12a2.

[0123] In this way, it is beneficial to match the area of the first light-emitting device 13a with the life ranking of the first light-emitting device 13a (the ranking among the three devices), and to match the area of the second light-emitting device 13b with the life ranking of the second light-emitting device 13b (the ranking among the three devices), thereby maximizing the service life of the display panel 10.

[0124] In one embodiment, Figure 5 As shown, the first projected figure S1 includes two fifth sides S13 and four sixth sides S14. The two fifth sides S13 are located on either side of the first projected figure S1 along the second direction Y, and each fifth side S13 connects to two second overlapping sides S12 on either side of the same accommodating space S1a. The two sixth sides S14 are located on one side of the first projected figure S1 along the second direction Y, and the other two sixth sides S14 are located on the other side of the first projected figure S1 along the second direction Y. Each sixth side S14 connects to a first overlapping side S11 and a second overlapping side S12.

[0127] In one embodiment, the first projection pattern S1 is in an H-shape.

[0128] In one embodiment, Figure 8 As shown, a second protrusion S3a is formed on one side of the third projection pattern S3 along the second direction Y, and a portion of the second protrusion S3a extends into the accommodation space S1a of the first projection pattern S1, so that the second protrusion S3a and the accommodation space S1a achieve a "concave-convex" fit.

[0129] In one embodiment, the third projection pattern S3 further includes a second main portion S3b, and the second protrusion S3a is located on one side of the second main portion S3b along the second direction Y. Each fourth overlapping edge S31 includes a third sub-overlapping edge S311 and a fourth sub-overlapping edge S312. The third sub-overlapping edges S311 of the two fourth overlapping edges S31 are respectively located on both sides of the second main portion S3b along the first direction X, and the fourth sub-overlapping edges S312 of the two fourth overlapping edges S31 are respectively located on both sides of the second protrusion S3a along the first direction X.

[0130] In this way, the second electrode 133 of the third light-emitting device 13c not only overlaps with the isolation structure 12 corresponding to the third sub-overlap edge S311, but also overlaps with the isolation structure 12 corresponding to the fourth sub-overlap edge S312, and the total length of the fourth overlap edge S31 will not be reduced due to the provision of the second protrusion S3a, which is beneficial to ensuring the overlap area of the second electrode 133 of the second light-emitting device 13b.

[0131] In one embodiment, the third sub-overlapping edge S311 is perpendicular to the first direction X. Thus, when evaporating the second electrode 133 , the evaporation source is scanned along the first direction X. The second electrode 133 has the highest overlapping height, the largest overlapping area, and the lowest overlapping impedance on the isolation structure 12 corresponding to the third sub-overlapping edge S311 , thereby improving the display effect.

[0132] In one embodiment, the fourth sub-overlapping edge S312 is perpendicular to the first direction X. Thus, when evaporating the second electrode 133 , the evaporation source is scanned along the first direction X. The second electrode 133 has the highest overlapping height, the largest overlapping area, and the lowest overlapping impedance on the isolation structure 12 corresponding to the fourth sub-overlapping edge S312 , thereby improving the display effect.

[0133] In one embodiment, the third projection figure S3 further includes a seventh side S32, an eighth side S33 and two ninth sides S34; the seventh side S32 is located on the side of the second main body portion S3b away from the second protrusion S3a, and connects the two third sub-overlapping edges S311; the eighth side S33 is located on the side of the second protrusion S3a away from the second main body portion S3b, and connects the two fourth sub-overlapping edges S312; the two ninth sides S34 are located on the side of the second main body portion S3b close to the second protrusion S3a, and each ninth side S34 connects a third sub-overlapping edge S311 and a fourth sub-overlapping edge S312.

[0136] It should be emphasized here that, in the actual manufacturing process, due to process errors, the edges of the first projection figure S1 (the second projection figure S2, the third projection figure S3) are not absolutely straight lines. It is also possible that burrs may easily exist on the side wall of the isolation structure 12 close to the isolation opening 12a (for example, the side wall of the base 123 close to the isolation opening 12a), resulting in burrs on the edges of the first projection figure S1 (the second projection figure S2, the third projection figure S3). That is, the edges of the first projection figure S1 (the second projection figure S2, the third projection figure S3) are not absolutely straight lines.
