[0037] Hereinafter, a display panel 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0038] like Figure 1-Figure 3 As shown, according to the embodiment of the utility model, the display panel 100 includes a substrate body 1 and a frame sealant 2, the substrate body 1 includes a first substrate 11 and a second substrate 12 arranged opposite to each other, and the substrate body 1 has a first substrate edge 13, a second substrate edge 14 and a third substrate edge 15 adjacent to each other in sequence, a first transition edge 17 is connected between the first substrate edge 13 and the second substrate edge 14, a second transition edge 18 is connected between the second substrate edge 14 and the third substrate edge 15, the curvature radius of the first transition edge 17 is r1, the curvature radius of the second transition edge 18 is r2, r1≥r2; the frame sealant 2 is sealed and connected between the first substrate 11 and the second substrate 12, and the frame sealant 2 has The first glue frame edge 21, the second glue frame edge 22 and the third glue frame edge 23 are adjacent in sequence, and the first glue frame edge 21 to the third glue frame edge 23 correspond to the first substrate edge 13 to the third substrate edge 15 one by one respectively. A third transition edge 25 is connected between the first glue frame edge 21 and the second glue frame edge 22, and a fourth transition edge 26 is connected between the second glue frame edge 22 and the third glue frame edge 23. The spacing between the first glue frame edge 21 and the first substrate edge 13 is greater than the spacing between the third glue frame edge 23 and the third substrate edge 15. The curvature radius of the third transition edge 25 is R1, and the curvature radius of the fourth transition edge 26 is R2, r1>R1, r2≥R2, and R1<R2.

[0039] Therefore, by setting the curvature radius of the fourth transition edge 26 to be greater than the curvature radius of the third transition edge 25, the glue width loss of the fourth transition edge 26 in the rounding process (including rounding the substrate body 1 to form the first transition edge 17 and the second transition edge 18) when the display panel 100 is asymmetrically designed (the distance between the first glue frame edge 21 and the first substrate edge 13 is greater than the distance between the third glue frame edge 23 and the third substrate edge 15) can be improved, which is beneficial for the portion of the frame sealing glue 2 corresponding to the fourth transition edge 26 to retain a suitable glue width, thereby improving the bonding strength of the substrate body 1 corresponding to the fourth transition edge 26, so as to improve the supporting strength of the fourth transition edge 26, and further improve the high temperature and high humidity reliability and drop resistance of the display panel 100, which is beneficial to improving the quality of the display panel 100.

[0040] Among them, by setting the curvature radius of the first transition edge 17 to be greater than the curvature radius of the third transition edge 25, and the curvature radius of the second transition edge 18 to be greater than or equal to the curvature radius of the fourth transition edge 26, it is convenient for the first transition edge 17 to be located outside the third transition edge 25 and the second transition edge 18 to be located outside the fourth transition edge 26, so as to reduce the glue width loss of the portion of the sealing glue 2 corresponding to the third transition edge 25 and the fourth transition edge 26 during the rounding process, so that the third transition edge 25 and the fourth transition edge 26 can retain a larger glue width, so as to improve the supporting capacity of the third transition edge 25 and the fourth transition edge 26 corresponding to the corner of the substrate body 1.

[0041] In addition, it should be noted that the distance between the first frame edge 21 and the first substrate edge 13 is greater than the distance between the third frame edge 23 and the third substrate edge 15. It can be understood that the display panel 100 (substrate body 1) adopts an asymmetric design on both sides corresponding to the first substrate edge 13 and the third substrate edge 15. Therefore, by setting the curvature radius of the fourth transition edge 26 to be greater than the curvature radius of the third transition edge 25, that is, the fourth transition edge 26 of the sealing glue 2 is appropriately retracted to increase the curvature radius of the fourth transition edge 26, so that when the distance between the first glue frame edge 21 and the first substrate edge 13 is greater than the distance between the third glue frame edge 23 and the third substrate edge 15, under the premise of r1>R1, r2≥R2, and r1≥r2, it is convenient to make the fourth transition edge 26 away from the second transition edge 18, that is, the fourth transition edge 26 is away from the rounded corner position of the substrate body 1 corresponding to the fourth transition edge 26, which can reduce the glue width loss of the portion of the sealing glue frame 2 corresponding to the fourth transition edge 26 in the rounding process, so that after the rounding process, the fourth transition edge 26 can retain a larger glue width on the substrate body 1, and further can better improve the glue width loss of the portion of the sealing glue frame 2 corresponding to the fourth transition edge 26 in the rounding process when the above-mentioned display panel 100 adopts an asymmetric design.

[0042] It can be understood that, on a plane perpendicular to the thickness direction of the substrate body 1, the glue width of the frame sealant 2 is the radial width applied on the substrate body 1. Wherein, "radial" is understood in a broad sense, and the radial direction is on the plane where the substrate body 1 is located and perpendicular to the extension direction of the frame sealant 2, or on the plane where the substrate body 1 is located, passing through the central axis of the sealant frame 2. For example, the third transition edge 25 is an arc structure, and the radial width of the third transition edge 25 on the surface of the first substrate 11 is the glue width of the third transition edge 25. The rounding process is a process link in the process of manufacturing the rounded corner screen of the display panel 100, that is, the corner of the display panel 100 is designed with an arc. After the rounding process, the corresponding corner of the substrate body 1 is ground off to form the first transition edge 17 and the second transition edge 18 at the corresponding corner of the substrate body 1. Wherein, it can be understood that the curvature radius of the first transition edge 17 and the second transition edge 18 needs to match the design of the backlight mechanism 101 of the display device 200. Of course, it is understandable that the radius of curvature of the third transition edge 25 needs to be designed by comprehensively considering the design of the backlight mechanism 101 of the display device 200, the anti-drop performance of the display panel 100, and the reduction of the glue width loss in the rounded corner process. Simply understand that the radius of curvature of the third transition edge 25 is set according to product requirements, and the radius of curvature of the fourth transition edge 26 is adjusted according to the radius of curvature of the third transition edge 25. It can be seen that the radius of the third transition edge 25 may be adjusted according to actual needs. Of course, in the embodiment of the present application, by setting the radius of curvature of the first transition edge 17 to be greater than the radius of curvature of the third transition edge 25, the situation of insufficient support caused by the radius adjustment of the third transition edge 25 can be prevented.

[0043] Optionally, the first transition edge 17 and the second transition edge 18 have the same curvature radius, and the first transition edge 17 and the second transition edge 18 have the same shape structure, the second transition edge 18 is arranged corresponding to the fourth transition edge 26, and the shape structure of the second transition edge 18 and the fourth transition edge 26 are arranged in parallel. Optionally, the shapes of the first transition edge 17, the second transition edge 18, the third transition edge 25 and the fourth transition edge 26 can be arc structures or curve structures. It can be understood that when the shapes of the first transition edge 17, the second transition edge 18, the third transition edge 25 and the fourth transition edge 26 are non-arc structures, the curvature radius corresponding to any point of the fourth transition edge 26 is greater than the curvature radius corresponding to any point of the third transition edge 25, the curvature radius corresponding to any point of the first transition edge 17 is greater than the curvature radius corresponding to any point of the third transition edge 25, and the curvature radius corresponding to any point of the second transition edge 18 is greater than or equal to the curvature radius corresponding to any point of the fourth transition edge 26.

[0044] Specifically, before the rounding process is performed on the substrate body 1, Figure 1-Figure 4 The substrate body 1 includes a first substrate 11 and a second substrate 12, which are sequentially arranged along the thickness direction of the display panel 100, and the sealant 2 is located between the first substrate 11 and the second substrate 12. The substrate body 1 includes a first substrate edge 13, a second substrate edge 14 and a third substrate edge 15 which are sequentially connected, the first substrate edge 13 and the second substrate edge 14 form a first corner 1a, the second substrate edge 14 and the third substrate edge 15 form a second corner 1b, and the first substrate edge 13 and the third substrate edge 15 are arranged opposite to each other along the left-right direction of the substrate body 1.

[0045] The first substrate 11 has a glue coating area 111 (e.g., a dummy area) and a first attachment area 112 (e.g., a light bar attachment area) located on one side of the glue coating area 111 in the left-right direction of the substrate body 1. The first substrate edge 13 is the edge corresponding to the first attachment area 112 corresponding to the substrate body 1. The first attachment area 112 is located between the first substrate edge 13 and the first glue frame edge 21. The sealant 2 is applied to the glue coating area 111 by a glue coating device (e.g., a Seal Dispenser device), and the first substrate 11 and the second substrate 12 are bonded to form an unprocessed substrate body 1. The sealing frame 2 includes a first frame edge 21, a second frame edge 22 and a third frame edge 23 which are adjacent to each other in sequence. The first frame edge 21 to the third frame edge 23 correspond to the first substrate edge 13 to the third substrate edge 15 one by one and are arranged in parallel, that is, the first frame edge 21 corresponds to and is parallel to the first substrate edge 13, the second frame edge 22 corresponds to and is parallel to the second substrate edge 14, the third frame edge 23 corresponds to and is parallel to the third substrate edge 15, a third transition edge 25 is connected between the first frame edge 21 and the second frame edge 22, a fourth transition edge 26 is connected between the second frame edge 22 and the third frame edge 23, and the third transition edge 25 corresponds to the first corner 1a, and the fourth transition edge 26 corresponds to the second corner 1b.

[0046] The distance between the first glue frame edge 21 and the first substrate edge 13 is the width of the first attachment area 112 in the left-right direction of the substrate body 1, the second glue frame edge 22 is arranged adjacent to the second substrate edge 14, the third glue frame edge 23 is arranged adjacent to the third substrate edge 15, and the distance between the first glue frame edge 21 and the first substrate edge 13 is greater than the distance between the third glue frame edge 23 and the third substrate edge 15. Among them, the third transition edge 25 and the fourth transition edge 26 are both arc-shaped structures, and the radius of the fourth transition edge 26 is greater than the radius of the third transition edge 25, that is, the glue coating radius of the fourth transition edge 26 is greater than the glue coating radius of the third transition edge 25.

[0047] Among them, the first corner 1a and the second corner 1b of the substrate body 1 are respectively provided with cutting lines (such as Cutting cutting lines) corresponding to the first transition edge 17 and the second transition edge 18, the first transition edge 17 and the second transition edge 18 are both arc-shaped structures, and the radii of the first transition edge 17 and the second transition edge 18 are equal, and the radius of the first transition edge 17 is greater than the radius of the third transition edge 25 and the fourth transition edge 26.

[0048] When the corresponding device cuts along the cutting line of the first transition edge 17 and the second transition edge 18, the first transition edge 17 and the second transition edge 18 are formed at the corresponding positions of the corners of the substrate body 1, and the first transition edge 17 is connected between the first substrate edge 13 and the second substrate edge 14, and the second transition edge 18 is connected between the second substrate edge 14 and the third substrate edge 15. In this way, the rounded corner design of the display panel 100 can be realized, and the first transition edge 17 is located outside the third transition edge 25, and the second transition edge 18 is located outside the fourth transition edge 26. Therefore, the glue width loss of the corresponding part of the fourth transition edge 26 when the display panel 100 is asymmetrically designed can be improved, that is, the glue width of the corresponding part of the fourth transition edge 26 worn by the rounding process is reduced, so that the fourth transition edge 26 can retain a suitable glue width, and the supporting strength of the corresponding corner of the substrate body 1 corresponding to the fourth transition edge 26 can be improved, and the high temperature and high humidity reliability and anti-drop performance of the display panel 100 can be improved.

[0049] In the related art, the display panel adopts an asymmetric design between the edge of the first substrate and the edge of the third substrate, and the radius of the third transition edge and the fourth transition edge are equal, that is, the radius of the glue coating of the corner of the substrate body corresponding to the frame sealant is equal. After the substrate body is subjected to the rounding process, since the distance between the edge of the first glue frame and the edge of the first substrate is greater than the distance between the edge of the third glue frame and the edge of the third substrate, the third transition edge is basically not worn by the rounding process, and the fourth transition edge will be worn by the rounding process. The glue width of the fourth transition edge is relatively low, which will make the display panel prone to corner peeling during the reliability evaluation or drop test, and will cause defects such as leakage of the display panel (such as bubble defects).

[0050] In an embodiment of the present application, by setting the radius of the fourth transition edge 26 to be larger than the radius of the third transition edge 25, the glue coating position of the fourth transition edge 26 is appropriately retracted inward, so that the fourth transition edge 26 is away from the second transition edge 18, that is, the fourth transition edge 26 is away from the rounded position, thereby reducing the glue width of the corresponding part of the fourth transition edge 26 worn by the rounding process, so that the corresponding part of the fourth transition edge 26 can retain a larger glue width, which can effectively improve the leakage caused by corner peeling in high temperature and high humidity reliability, and can improve the quality of the display panel 100.

[0051] Specifically, for the 900μm designed glue width of the corresponding parts of the third transition edge and the fourth transition edge. In the above-mentioned related art, because the radii of the third transition edge and the fourth transition edge are equal, the fourth transition edge will be partially worn during the rounding process. The inventors have found through experiments that the designed glue width (dry glue width) of the corresponding part of the fourth transition edge may be worn away by a width of about 100μm, so the glue width of the fourth transition edge is low. In the embodiment of the present application, because the present application adopts a design in which the radius of the fourth transition edge 26 is greater than the radius of the third transition edge 25, the inventors have found through experiments that the designed glue width of the fourth transition edge 26 may be worn away by a width of about 50μm. In the embodiment of the present application, the loss of the glue width of the fourth transition edge 26 in the rounding process can be reduced.

[0052] For example, in the above-mentioned related art, the radius of the third transition edge and the fourth transition edge is 1.6mm, the radius of the first transition edge (rounded corner radius) is 4mm, and the radius of the second transition edge (rounded corner radius) is 2.5mm. After the rounded corner process, the glue width of the corresponding part of the third transition edge is 1169μm, and the glue width of the fourth transition edge is only 749μm. In the embodiment of the present application, the radius of the third transition edge 25 is 1.6mm, the radius of the fourth transition edge 26 is 1.8mm, the radius of the first transition edge is 4mm, and the radius of the second transition edge is 2.5mm. After the rounded corner process, the glue width of the third transition edge 25 is 1130μm, and the glue width of the fourth transition edge 26 is 870μm. Therefore, compared with the solution in the above-mentioned related art in which the radius of the fourth transition edge 26 is equal to the radius of the third transition edge 25, the glue width of the fourth transition edge 26 increases by about 120μm. It should be noted that due to fluctuations in the glue coating process, the actual glue coating width will have a certain deviation, that is, the actual glue coating width is 900μm±200μm.

[0053] Therefore, the inventors have found that when the distance between the first glue frame edge 21 and the first substrate edge 13 is greater than the distance between the third glue frame edge 23 and the third substrate edge 15, the curvature radius of the fourth transition edge 26 is set to be greater than the curvature radius of the third transition edge 25. After the corners of the substrate body 1 corresponding to the fourth transition edge 26 and the third transition edge 25 are rounded, the glue width loss of the fourth transition edge 26 can be effectively reduced, and the loss of the glue width of the fourth transition edge 26 caused by the rounding process when the display panel 100 adopts an asymmetric design can be improved, thereby fully ensuring the better high temperature and high humidity reliability and drop resistance of the display panel 100.

[0054] In the above technical scheme, when the distance between the first glue frame edge 21 and the first substrate edge 13 is greater than the distance between the third glue frame edge 23 and the third substrate edge 15, under the premise of r1>R1, r2≥R2, and r1≥r2, by setting the curvature radius of the fourth transition edge 26 to be greater than the curvature radius of the third transition edge 25, the glue width loss of the fourth transition edge 26 in the rounding process when the substrate body 1 is asymmetrically designed can be improved, which is beneficial for the fourth transition edge 26 to retain a suitable glue width, thereby improving the bonding strength of the substrate body 1 corresponding to the fourth transition edge 26, so as to improve the supporting strength of the fourth transition edge 26, and at the same time prevent the situation of insufficient support caused by the radius adjustment of the third transition edge 25, thereby improving the high temperature and high humidity reliability and drop resistance of the display panel 100, which is beneficial to improving the quality of the display panel 100.

[0055] In some embodiments of the present application, R2 is less than 1.5*R1. Thus, the radius of curvature of the fourth transition edge 26 is within a reasonable range, so that the fourth transition edge 26 is at a suitable distance from the corresponding corner of the substrate body 1, and the fourth transition edge 26 can improve the corresponding corner of the substrate body 1. The supporting strength has a suitable strength. Secondly, the design of the radius of curvature of the fourth transition edge 26 is more reasonable, and the requirements for the glue coating equipment are relatively low, which is convenient for the glue coating equipment to coat and form the fourth transition edge 26. Optionally, R2 can be 1.49*R1, 1.4*R1, 1.3*R1, 1.2*R1, or 1.1875*R1, etc.

[0056] In some embodiments of the present application, R2≤1.1875*R1. Thus, the radius of curvature of the fourth transition edge 26 is further within a more reasonable range, so that the fourth transition edge 26 and the corresponding corner of the substrate body 1 are at a more reasonable distance, which can improve the fourth transition edge 26 to have a more appropriate support strength for the corresponding corner of the substrate body 1. Optionally, R2 can be 1.1875*R1, 1.17*R1, 1.16*R1, 1.15*R1, 1.14*R1, 1.13*R1, or 1.125*R1.

[0057] In some embodiments of the present application, R2≤1.125*R1. Thus, the radius of curvature of the fourth transition edge 26 is better within a more reasonable range, and the fourth transition edge 26 is further at a more reasonable distance from the corresponding corner of the substrate body 1, further improving the fourth transition edge 26 to have a more appropriate support strength for the corresponding corner of the substrate body 1. Optionally, R2 can be 1.125*R1, 1.11*R1, 1.1*R1, or 1.09*R1, etc.

[0058] In some embodiments of the present application, Figure 1 , the distance between the first rubber frame edge 21 and the first substrate edge 13 is greater than the distance between the second rubber frame edge 22 and the second substrate edge 14. Therefore, it is convenient to have a certain space between the first rubber frame edge 21 and the first substrate edge 13 to arrange related components (such as the light source component 102 described later), and it is convenient to limit the distance between the second rubber frame edge 22 and the second substrate edge 14, so that the second rubber frame edge 22 and the second substrate edge 14 can have a smaller distance, which is conducive to realizing a narrow frame design.

[0059] In some embodiments of the present application, Figure 1 , the first transition edge 17 to the fourth transition edge 26 are all arc-shaped. Therefore, it is helpful to simplify the processing difficulty of the first transition edge 17 and the second transition edge 18, and reduce the difficulty of gluing the third transition edge 25 and the fourth transition edge 26. Of course, arc-shaped gluing can effectively improve the situation where the gluing of the corresponding corner of the substrate body 1 is locally wider during right-angle coating, and can reduce the occurrence of situations such as overflowing glue or poor cutting.

[0060] In some embodiments of the present application, Figure 1 The display panel 100 is a square structure, the substrate body 1 further includes a fourth substrate edge 16 connecting the first substrate edge 13 and the third substrate edge 15, the sealant 2 further includes a fourth glue frame edge 24 connecting the first glue frame edge 21 and the third glue frame edge 23, the distance between the fourth glue frame edge 24 and the fourth substrate edge 16 is greater than the distance between the second glue frame edge 22 and the second substrate edge 14, and the first substrate 11 has a binding portion for binding the chip at the fourth substrate edge 16. Therefore, it is convenient to have a certain space between the fourth glue frame edge 24 and the fourth substrate edge 16 to set the binding portion, and at the same time further limit the distance between the second glue frame edge 22 and the second substrate edge 14, so that the second glue frame edge 22 and the second substrate edge 14 can be designed to have a smaller distance, which is conducive to realizing a narrow frame design.

[0061] Optionally, combined Figure 3, a fifth transition edge 27 is connected between the first glue frame edge 21 and the fourth glue frame edge 24, a sixth transition edge 28 is connected between the third glue frame edge 23 and the fourth glue frame edge 24, the curvature radius of the fifth transition edge 27 is R3, the curvature radius of the sixth transition edge 28 is R4, R3=R4, and R2>R1>R3=R4. Thus, while ensuring that the glue width loss of the third transition edge 25 is reduced, so that the fifth transition edge 27 and the sixth transition edge 28 are close to the corresponding corner of the substrate body 1, the support strength of the fifth transition edge 27 and the sixth transition edge at the corresponding corner of the substrate body 1 can be improved, thereby improving the support capacity of the frame sealant 2.

[0062] Optionally, combined Figure 3 , a seventh transition edge 19 is connected between the first substrate edge 13 and the fourth substrate edge 16, an eighth transition edge 20 is connected between the third substrate edge 15 and the fourth substrate edge 16, the curvature radius of the seventh transition edge 19 is r3, the curvature radius of the eighth transition edge 20 is r4, and r3≥r4. Optionally, r1=r2=r3=r4, which can make the overall structure of the substrate body 1 symmetrical, easy to hold and carry, and conducive to improving the aesthetics of the display panel 100.

[0063] In some embodiments of the present application, Figure 3 , the thickness of the portion of the sealant 2 corresponding to the third transition edge 25 is T1, and the thickness of the portion of the sealant 2 corresponding to the fourth transition edge 26 is T2, and T1<T2. Therefore, by setting the thickness of the fourth transition edge 26 portion to be greater than the thickness of the third transition edge 25 portion, that is, setting the sealant width of the fourth transition edge 26 portion to be greater than the sealant width of the third transition edge 25 portion, the support strength of the fourth transition edge 26 on the corresponding corner of the substrate body 1 can be improved, thereby improving the high temperature and high humidity reliability and anti-drop performance of the display panel 100. Secondly, the sealant width of the fourth transition edge 26 can be increased, so that the fourth transition edge 26 can retain a suitable sealant width after the rounding process.

[0064] It can be understood that the thickness of the portion of the frame sealant 2 corresponding to the fourth transition edge 26 is greater than the thickness of the portion of the frame sealant 2 corresponding to the third transition edge 25, and it can be understood that after the rounded corner process, the width of the glue corresponding to the fourth transition edge 26 is greater than the width of the glue corresponding to the third transition edge 25. For example, before the rounded corner process, the width of the glue corresponding to the fourth transition edge 26 coated by the glue coating equipment is greater than the width of the glue corresponding to the third transition edge 25, and after the rounded corner process, the width of the glue corresponding to the fourth transition edge 26 is greater than the width of the glue corresponding to the third transition edge 25.

[0065] Optionally, during the coating process of the frame sealing glue 2, by setting the coating speed of the fourth transition edge 26 to be lower than the coating speed of the third transition edge 25, that is, at the same unit glue dispensing amount, the coating device has a larger glue dispensing amount when coating the fourth transition edge 26, the fourth transition edge 26 can have a wider glue width, so that the thickness of the fourth transition edge 26 is greater than the thickness of the third transition edge 25. Alternatively, by setting the glue dispensing amount of the fourth transition edge 26 to be higher than the glue dispensing amount of the third transition edge 25, that is, at the same coating speed, the coating device has a larger glue dispensing amount per unit time when coating the fourth transition edge 26, the fourth transition edge 26 can have a wider glue width, so that the thickness of the fourth transition edge 26 is greater than the thickness of the third transition edge 25.

[0066] In some embodiments of the present application, Figure 1 , the first transition edge 17 to the fourth transition edge 26 are all arc-shaped, the distance between the third transition edge 25 and the first reference is smaller than the distance between the fourth transition edge 26 and the second reference, the first reference is the outer wall of the first rounded corner portion connected between the first glue frame edge 21 and the second glue frame edge 22 and having the same thickness as the corresponding portion of the first glue frame edge 21 and the second glue frame edge 22, and the second reference is the outer wall of the second rounded corner portion connected between the second glue frame edge 22 and the third glue frame edge 23 and having the same thickness as the corresponding portion of the second glue frame edge 22 and the second glue frame edge 22. Therefore, the fourth transition edge 26 has a wider glue width than the third transition edge 25, which can improve the support strength of the fourth transition edge 26 to the corresponding corner of the substrate body 1, thereby improving the high temperature and high humidity reliability and drop resistance of the display panel 100.

[0067] It can be understood that the spacing between the third transition edge 25 and the first datum is smaller than the spacing between the fourth transition edge 26 and the second datum, then the difference between the glue width of the fourth transition edge 26 and the glue width of the second glue frame edge 22 is greater than the difference between the glue width of the third transition edge 25 and the glue width of the second glue frame edge 22, that is, the glue width of the fourth transition edge 26 is greater than the glue width of the third transition edge 25, so as to achieve that the thickness of the fourth transition edge 26 is greater than the thickness of the third transition edge 25, so that the fourth transition edge 26 can have a suitable glue width, so that the fourth transition edge 26 can provide suitable support strength for the corresponding angle of the substrate main body 1 to ensure the structural stability of the substrate main body 1.

[0068] For example, combined with Figure 1 and Figure 2The display panel 100 includes a substrate body 1, the substrate body 1 includes a first substrate 11 and a second substrate 12, and a sealant 2 is disposed between the first substrate 11 and the second substrate 12, so as to fill the liquid crystal 5 between the first substrate 11 and the second substrate 12. Exemplarily, the display panel 100 is a TFT LCD screen, the first substrate 11 is a CF substrate, and the second substrate 12 is a TFT substrate.

[0069] Combination Figure 3 The substrate body 1 includes a first substrate edge 13, a second substrate edge 14, a third substrate edge 15 and a fourth substrate edge 16 which are adjacent to each other in sequence, a first transition edge 17 is connected between the first substrate edge 13 and the second substrate edge 14, a second transition edge 18 is connected between the second substrate edge 14 and the third substrate edge 15, a seventh transition edge 19 is connected between the first substrate edge 13 and the fourth substrate edge 16, and an eighth transition edge 20 is connected between the third substrate edge 15 and the fourth substrate edge 16, so that the substrate body 1 is formed into an approximately rectangular structure. Exemplarily, the first substrate edge 13 (e.g., GPR) is a light bar edge, the third substrate edge 15 (e.g., GPL) is a light bar opposite edge, the fourth substrate edge 16 (e.g., DP) is an electrode edge, and the second substrate edge 14 (e.g., DPO) is an electrode opposite edge.

[0070] Combination Figure 4 and Figure 5-Figure 8 , taking the first substrate edge 13, the second substrate edge 14, the third substrate edge 15, the fourth substrate edge 16, the first transition edge 17, the second transition edge 18, the seventh transition edge 19 and the eighth transition edge 20 as the edges of the first substrate 11 as an example, the first substrate 11 has a glue-coated area 111, a first attachment area 112 and a second attachment area 113, the first attachment area 112 is located on the left side of the glue-coated area 111, the second attachment area 113 is located on the lower side of the glue-coated area 111, and the glue-coated area 111, the first attachment area 112 and the second attachment area 113 are all formed into a square-like structure. The first substrate edge 13 is configured as a partial edge of the first attachment area 112, the second substrate edge 14 and the third substrate edge 15 are configured as partial edges of the glue-coated area 111, and the fourth substrate edge 16 is configured as a partial edge of the second attachment area 113.

[0071] Among them, the left side of the glue-coated area 111 is the first attachment area 112, which can be understood as the display panel 100 (substrate body 1) adopts an asymmetric design in the left and right directions (such as GPL and GPR asymmetric design), and the portion of the display panel 100 corresponding to the glue-coated area 111 includes the display area 10, and the first attachment area 112 is located on the left side of the display area 10. Exemplarily, the first attachment area 112 is the light bar attachment area of ​​the display panel 100, and the second attachment area 113 is the data signal area or the external circuit attachment area, which can be used for CT detection and external line access, or for pasting ICs and FPCs, or for applying Ag glue points, or for reserving positions for screen ID coding, etc.

[0072] The glue coating device coats the sealing glue 2 on the glue coating area 111, and the sealing glue 2 includes a first glue frame edge 21, a second glue frame edge 22, a third glue frame edge 23 and a fourth glue frame edge 24 which are adjacent to each other in sequence. The first glue frame edge 21 to the fourth glue frame edge 24 correspond to the first substrate edge 13 to the fourth substrate edge 16 respectively, and a third transition edge 25 is connected between the first glue frame edge 21 and the second glue frame edge 22, a fourth transition edge 26 is connected between the second glue frame edge 22 and the third glue frame edge 23, a fifth transition edge 27 is connected between the first glue frame edge 21 and the fourth glue frame edge 24, and a sixth transition edge 28 is connected between the third glue frame edge 23 and the fourth glue frame edge 24.

[0073] In addition, the first transition edge 17 to the eighth transition edge 20 are all formed into an arc structure, the radius of the first transition edge 17 is r1, the radius of the second transition edge 18 is r2, the radius of the seventh transition edge 19 is r3, and the radius of the eighth transition edge 20 is r4, r1 = r2 = r3 = r4. The radius of the third transition edge 25 is R1, the radius of the fourth transition edge 26 is R2, the radius of the fifth transition edge 27 is R3, and the radius of the sixth transition edge 28 is R4, R2>R1>R3=R4.

[0074] Of course, it should be noted that the first transition edge 17 and the second transition edge 18 are formed by cutting the substrate body 1 through a rounding process, and the seventh transition edge 19 and the eighth transition edge 20 are formed by chamfering or rounding the substrate body 1.

[0075] Therefore, by setting the radius of the fourth transition edge 26 to be larger than the radius of the third transition edge 25, that is, the glue coating radius of the fourth transition edge 26 corresponding to the frame sealing glue 2 is larger than the glue coating radius of the third transition edge 25, the fourth transition edge 26 can be away from the second transition edge 18, thereby improving the glue width loss of the fourth transition edge 26 due to the asymmetric design of the display panel 100, and allowing the fourth transition edge 26 to retain a suitable glue width to ensure that the fourth transition edge 26 has a suitable supporting strength at the corner corresponding to the substrate body 1. At the same time, it can better cooperate with the third transition edge 25, and to a certain extent avoid the insufficient angle support corresponding to the third transition edge 25 when the radius of the third transition edge 25 is adjusted to meet the needs, thereby improving the high temperature and high humidity reliability and drop resistance of the display panel 100, and improving the quality of the display panel 100.

[0077] In the above technical solution, by adopting the above display panel 100, the performance of the display device can be improved.

[0078] In some embodiments of the present application, Figure 2 , Figure 4 , Figure 5 and Figure 7 , the display panel 100 is a liquid crystal display panel, and the display device further includes a light source 102, which is disposed between the first substrate 11 and the second substrate 12, and between the first rubber frame edge 21 and the first substrate edge 13. Thus, the light source 102 can supplement the light source for the display panel 100, and the light source 102 can utilize part of the setting space of the display panel 100, so that the light source 102 and the display panel 100 are arranged more compactly, which is conducive to reducing the thickness of the display device.

[0079] Optionally, the display device further includes a backlight mechanism 101 , which is disposed on a side of the second substrate 12 away from the first substrate 11 , so that the backlight mechanism 101 provides sufficient and uniform light source for the display panel 100 to achieve normal operation of the display panel 100 .

[0080] For example, combined with Fig. 9 The display panel 100 also includes an upper polarizing plate 3 and a lower polarizing plate 4. The upper polarizing plate 3 is arranged on a side of the first substrate 11 away from the second substrate 12, and the lower polarizing plate 4 is arranged on a side of the second substrate 12 away from the first substrate 11, and the lower polarizing plate 4 is located between the second substrate 12 and the backlight mechanism 101.
