For example, as shown in fig. 10, a first decelerating wall 32 is disposed on a side of the sealant 33 close to the cutting boundary 13 to slow down the flowing speed of the sealant 33 toward the cutting boundary 13; the first separation retaining wall 31 is arranged on one side of the first speed reduction retaining wall 32 close to the cutting boundary 13, a first accommodating cavity 41 is formed between the first separation retaining wall 31 and the first speed reduction retaining wall 32, the frame glue 33 decelerated by the first speed reduction retaining wall 32 flows through the first speed reduction retaining wall 32 and is accommodated in the first accommodating cavity 41, and the frame glue 33 continues to fill the part, which is not filled with the frame glue 33, in the first accommodating cavity 41 along the first separation retaining wall 31 due to the blocking of the first separation retaining wall 31 in the process that the frame glue 33 flows to the first separation retaining wall 31, so that the speed of the frame glue 33 flowing to the cutting boundary 13 is further slowed down, and the frame glue 33 is better prevented from flowing to the cutting boundary 13. The first blocking wall 31 includes a first sub-blocking wall 311, a second sub-blocking wall 312 and a third sub-blocking wall 313 which are sequentially arranged along the first direction X, the first sub-blocking wall 311 and the third sub-blocking wall 313 are arranged on the first substrate 21, the second sub-blocking wall 312 is arranged on the second substrate 22, wherein the first substrate 21 may be an array substrate, and the second substrate 22 is a color film substrate, or the first substrate 21 is a color film substrate, and the second substrate 22 is an array substrate. When the first substrate 21 and the second substrate 22 are assembled to the cassette, the second sub-partition wall 312 is linearly overlapped with the first sub-partition wall 311 and the third sub-partition wall 313 respectively to perform an alignment function, so that the situation of the joint dislocation of the first substrate 21 and the second substrate 22 is improved, and the joint precision of the first substrate 21 and the second substrate 22 is improved. A groove structure 61 is formed between the first accommodating sidewall 51 and the second accommodating sidewall 52, and a second accommodating cavity 42 is formed by the groove structure 61 and a gap between the first sub-partition wall 311 and the third sub-partition wall 313, so that the first accommodating sidewall 51 and the second accommodating sidewall 52 have a certain elastic space, which is helpful for further improving the condition of joint dislocation of the first substrate 21 and the second substrate 22 and improving the joint precision.
It should be noted that the groove structure 61 may have any shape, for example, the cross section of the groove structure 61 along the direction C-C' in fig. 9 may be rectangular or trapezoidal.
In the display panel provided in the embodiment of the present invention, the first blocking wall 31, the first decelerating wall 32 and the sealant 33 are sequentially disposed in the non-display region 12 along the direction in which the non-display region 12 points to the display region 11, and the first decelerating wall 32 slows down the flow speed of the sealant 33 toward the cutting boundary 13; the first accommodating cavity 41 is formed between the first speed-reducing retaining wall 32 and the first separation retaining wall 31 to accommodate the frame glue 33, so that the frame glue 33 is prevented from flowing to the position of the cutting boundary 13, the problem that the cut display panel is broken and defective due to the fact that the frame glue 33 is diffused to the cutting boundary 13 is avoided, meanwhile, the frame glue 33 is prevented from flowing to the first separation retaining wall 31 and/or between the first speed-reducing retaining wall 32 and the substrate of the display panel, and the panel box thickness is prevented from being influenced; further through setting up first wall 31 and including the first sub wall 311, second sub wall 312 and third sub wall 313 that set gradually along first direction X, first sub wall 311 and third sub wall 313 set up on first base plate 21, second sub wall 312 sets up on second base plate 22, when first base plate 21 and second base plate 22 assemble the box, second sub wall 312 and first sub wall 311 and third sub wall 313 carry out linear overlap joint between the wall, play the effect of counterpoint, improve the condition of first base plate 21 and second base plate 22 laminating dislocation. Meanwhile, the second accommodating cavity 42 is formed by forming the groove structure 61 between the first accommodating side wall 51 and the second accommodating side wall 52, so that the first accommodating side wall 51 and the second accommodating side wall 52 have certain elastic spaces, which is beneficial to further improving the condition of joint dislocation of the first substrate 21 and the second substrate 22 and improving the joint precision.
With continued reference to fig. 10, alternatively, the first accommodating side wall 51 may be swingably provided between the first sub-blocking wall 311 and the third sub-blocking wall 313, and the second accommodating side wall 52 may be swingably provided between the first sub-blocking wall 311 and the third sub-blocking wall 313.
For example, fig. 11 is a schematic structural diagram of a first partition wall according to an embodiment of the present invention, as shown in fig. 11, the first accommodating sidewall 51 and the second accommodating sidewall 52 may be made of an elastic material, so that the first accommodating sidewall 51 and the second accommodating sidewall 52 can swing along with the flow of the sealant 33, and when the first accommodating cavity 41 is filled with the sealant 33, the sealant 33 extrudes the second accommodating sidewall 52 to make the second accommodating sidewall 52 swing toward the first accommodating sidewall 51, so that the sealant 33 flows into and is stored in the second accommodating cavity 42, and further the speed of the sealant 33 flowing toward the cutting boundary 13 is reduced. The frame glue 33 flowing into the second accommodating cavity 42 extrudes the first accommodating side wall 51 towards the first sub-partition wall 311, so that the first accommodating side wall 51 and the first sub-partition wall 311 are in close contact, the frame glue 33 is blocked by the first accommodating side wall 51 and the first sub-partition wall 311, the frame glue 33 is prevented from flowing to the cutting boundary 13 before curing, and the problem of poor collapse of the cut display panel caused by the fact that the frame glue 33 is diffused to the cutting boundary 13 is solved. Moreover, since the first accommodating sidewall 51 and the second accommodating sidewall 52 are swingably disposed, when the second substrate 22 and the first substrate 21 are assembled to the box, along with the decrease of the distance between the second substrate 22 and the first substrate 21, the first sub-partition wall 311 and the third sub-partition wall 313 squeeze the first accommodating sidewall 51 and the second accommodating sidewall 52, so that the first accommodating sidewall 51 and the second accommodating sidewall 52 swing toward the middle, and the second sub-partition wall 312 is in close contact with the first sub-partition wall 311 and the third sub-partition wall 313, respectively, which helps to block the sealant 33, and also leaves a certain error space for alignment between the first substrate 21 and the second substrate 22, and helps to assemble the box between the first substrate 21 and the second substrate 22. In addition, by arranging the groove structure 61 on the second sub-partition wall 312, and the second sub-partition wall 312 is in line contact with the first sub-partition wall 311 and the third sub-partition wall 313, the first accommodating sidewall 51 and the second accommodating sidewall 52 have a certain elastic space, and are more easily deformed and swung toward the center, so that the situation that the box thickness is increased due to the height error of the first partition wall 31 can be avoided, and the alignment assembly between the first substrate 21 and the second substrate 22 is facilitated. The groove structure 61 can also increase the storage capacity of the second accommodating cavity 42, and help prevent the sealant 33 from flowing to the cutting boundary 13 before curing.

By arranging at least one of the first side 72, the second side 75, the third side 76, and the fourth side 79 as an inclined surface, when the second substrate 22 and the first substrate 21 are assembled to the box, the second sub-partition wall 312 is extruded between the first sub-partition wall 311 and the third sub-partition wall 313 along with the approach of the second substrate 22 and the first substrate 21 until the second sub-partition wall 312 is in close contact with the first sub-partition wall 311 and the third sub-partition wall 313, which helps to prevent the sealant 33 from overflowing to the cutting boundary 13, and helps to correct the bonding dislocation between the first substrate 21 and the second substrate 22, and improves the bonding accuracy.
For example, as shown in fig. 12, the first side surface 72 and the fourth side surface 79 are inclined surfaces, the second sub-blocking wall 312 is in line contact with the first sub-blocking wall 311 and the third sub-blocking wall 313 respectively, which is more beneficial to the deformation and swing of the first accommodating side wall 51 and the second accommodating side wall 52, when the second substrate 22 and the first substrate 21 are assembled to each other, a larger alignment error space is firstly provided between the second sub-blocking wall 312 and the first sub-blocking wall 311 and the third sub-blocking wall 313, and as the second substrate 22 and the first substrate 21 approach, the second sub-blocking wall 312 gradually slides into the space between the first sub-blocking wall 311 and the third sub-blocking wall 313 until the second sub-blocking wall 312 is in close contact with the first sub-blocking wall 311 and the third sub-blocking wall 313, so as to help to correct the bonding dislocation between the first substrate 21 and the second substrate 22, and improve the bonding precision.
Fig. 13 is a schematic structural diagram of another first partition wall according to an embodiment of the present invention, as shown in fig. 13, optionally, the second side surface 75 and the third side surface 76 are inclined surfaces, and when the second substrate 22 and the first substrate 21 are assembled in a box, the second sub-partition wall 312 is extruded between the first sub-partition wall 311 and the third sub-partition wall 313 along with the approach of the second substrate 22 and the first substrate 21 until the second sub-partition wall 312 is in close contact with the first sub-partition wall 311 and the third sub-partition wall 313, which is helpful to prevent the sealant 33 from overflowing to the cutting boundary 13, and is also helpful to correct the joint misalignment between the first substrate 21 and the second substrate 22, so as to improve the joint accuracy.
In another embodiment, for example, fig. 14 is a schematic structural diagram of another first partition wall according to an embodiment of the present invention, as shown in fig. 14, the first side surface 72, the second side surface 75, the third side surface 76, and the fourth side surface 79 are all inclined surfaces, when the second substrate 22 and the first substrate 21 are assembled to each other, a larger alignment error space is firstly provided between the second sub-partition wall 312 and the first sub-partition wall 311 and between the second sub-partition wall 312 and the third sub-partition wall 313, and as the second substrate 22 and the first substrate 21 approach each other, the second sub-partition wall 312 gradually slides into between the first sub-partition wall 311 and the third sub-partition wall 313 until the second sub-partition wall 312 is in close contact with the first sub-partition wall 311 and the third sub-partition wall 313, so as to help correct the bonding misalignment between the first substrate 21 and the second substrate 22, and improve the bonding precision.
In summary, the embodiments of the present invention have described the shapes of the first sub-blocking wall 311, the second sub-blocking wall 312, and the third sub-blocking wall 313 in three feasible embodiments, and the embodiments of the present invention do not limit the specific shapes of the first sub-blocking wall 311, the second sub-blocking wall 312, and the third sub-blocking wall 313, and only need to ensure that the sealant 33 can be further prevented from overflowing to the cutting boundary 13, and at the same time, the embodiment of the present invention is helpful to correct the bonding misalignment between the first substrate 21 and the second substrate 22, so as to improve the bonding precision.
With continued reference to fig. 12, optionally, in the plane of the first top surface 71 and/or the third top surface 78, the distance between the first side surface 72 and the fourth side surface 79 in the first direction X is L1, and the maximum allowable alignment tolerance of the first substrate 21 and the second substrate 22 is L2, where L1 ≧ L2.
By setting L1 to be greater than or equal to L2, when the second substrate 22 and the first substrate 21 are assembled to each other, the second sub-partition retaining wall 312 easily falls between the first sub-partition retaining wall 311 and the third sub-partition retaining wall 313, so that the dislocation between the first substrate 21 and the second substrate 22 is corrected, and the attaching precision is improved.
Fig. 15 is a schematic structural view of another first partition wall according to an embodiment of the present invention, and as shown in fig. 15, a third receiving cavity 43 is optionally formed on a surface of the third top surface 78.
The third accommodating cavity 43 is formed on the surface of the third top surface 78, so that a part of the sealant 33 flowing to the third top surface 78 is stored in the third accommodating cavity 43, thereby increasing the volume of the first accommodating cavity 41 and further slowing down the flowing speed of the sealant 33.
With reference to fig. 10, optionally, the first decelerating retaining wall 32 at least includes a first sub decelerating retaining wall 321 and a second sub decelerating retaining wall 322 sequentially arranged along the first direction X, and the first sub decelerating retaining wall 321 and the second sub decelerating retaining wall 322 are arranged on different base plates.
As shown in fig. 16, the first decelerating barrier 32 includes a first sub-decelerating barrier 321 and a second sub-decelerating barrier 322 sequentially arranged along the first direction X, and the first decelerating barrier 321 and the second decelerating barrier 322 are disposed on different substrates, so that a narrow channel is formed between the first decelerating barrier 321 and the second decelerating barrier 322, and the sealant 33 flows in the narrow channel to slow down the flow speed, thereby helping to prevent the sealant 33 from flowing to the cutting boundary 13.
Fig. 16 is an enlarged schematic structural view of a region E in fig. 10, as shown in fig. 16, optionally, along a second direction Y, the distance between the first substrate 21 and the second substrate 22 is H, the height of the first sub-deceleration retaining wall 321 is H1, the height of the second sub-deceleration retaining wall 322 is H2, and the second direction Y is perpendicular to the plane where the first substrate 21 is located, where H1 is greater than or equal to 2/3 × H and less than or equal to 4/5 × H; h2 is not less than 2/3 and not more than 4/5.
Meanwhile, if H1 and H2 are greater than 4/5 × H, the sealant 33 is squeezed when flowing to the top positions of the first sub-deceleration retaining wall 321 and the second sub-deceleration retaining wall 322, so that the sealant 33 is accelerated to diffuse toward the cutting boundary 13. In addition, if h1 and h2 are less than 2/3 × h, the first decelerating barrier 32 may not have a good effect of slowing down the flow rate of the sealant 33. Therefore, in the embodiment of the present invention, by setting the appropriate height h1 of the first sub-deceleration retaining wall 321 and the appropriate height h2 of the second sub-deceleration retaining wall 322, the effect of reducing the flow rate of the sealant 33 is ensured, and the sealant 33 is prevented from extruding the tops of the first sub-deceleration retaining wall 321 and the second sub-deceleration retaining wall 322, so that the box thickness is increased.
With reference to fig. 16, optionally, the maximum allowable alignment fit error of the first base plate 21 and the second base plate 22 is L2, and the distance between the first sub-deceleration retaining wall 321 and the second sub-deceleration retaining wall 322 along the first direction X is L3, where L3 is greater than or equal to 1.2 × L2 and less than or equal to 1.5 × L2.
If the distance L3 between the first sub-decelerating barrier 321 and the second sub-decelerating barrier 322 is too small, the sealant 33 may be accumulated between the first sub-decelerating barrier 321 and the second sub-decelerating barrier 322, and the box thickness may be increased; if the distance L3 between the first sub-decelerating wall 321 and the second sub-decelerating wall 322 is too large, the effect of the first decelerating wall 32 for slowing down the flow rate of the sealant 33 is not good. In the embodiment of the present invention, by setting the appropriate distance L3 between the first sub-deceleration retaining wall 321 and the second sub-deceleration retaining wall 322, the effect of slowing down the flow rate of the sealant 33 is ensured, and meanwhile, the box thickness is prevented from being increased due to accumulation between the first sub-deceleration retaining wall 321 and the second sub-deceleration retaining wall 322.
With continued reference to fig. 16, optionally, the first sub-decelerating wall 321 comprises a first top portion 3211, and the second sub-decelerating wall 322 comprises a second top portion 3221, wherein the shape of the first top portion 3211 comprises a paraboloid or a cone, and the shape of the second top portion 3221 comprises a paraboloid or a cone.
By designing the shapes of the first top portion 3211 and the second top portion 3221 to be paraboloidal or pyramidal, the sealant 33 at the positions of the first top portion 3211 and the second top portion 3221 can be squeezed out all around, thereby preventing the sealant 33 from being accumulated on the first top portion 3211 and the second top portion 3221 to cause the box thickness to be raised.

Similarly, with reference to fig. 10, for example, the first sub-blocking wall 311 and the third sub-blocking wall 313 are disposed on the first substrate 21, the second sub-blocking wall 312 is disposed on the second substrate 22, and the sealant 33 overflows from the first accommodating chamber 41 to the top of the third sub-blocking wall 313, then flows down from the third sub-blocking wall 313 to the first substrate 21, and is filled from bottom to top in the second accommodating chamber 42, so as to slow down the flow speed of the sealant 33 to the cutting boundary 13.

Specifically, the second deceleration retaining wall 34 includes a third sub-deceleration retaining wall 341 and a fourth sub-deceleration retaining wall 342 sequentially arranged along the first direction X, and the third sub-deceleration retaining wall 341 and the fourth sub-deceleration retaining wall 342 are arranged on different substrates, so that a narrow channel is formed between the third sub-deceleration retaining wall 341 and the fourth sub-deceleration retaining wall 342, the sealant 33 flows in the narrow channel, and the flow speed is slowed down, thereby helping to block the sealant 33 from flowing to the display area 11. Similarly, the third decelerating barrier 36 at least includes a fifth sub decelerating barrier 361 and a sixth sub decelerating barrier 362 sequentially arranged along the first direction X, and the fifth decelerating barrier 361 and the sixth decelerating barrier 362 are disposed on different substrates, so that a narrow channel is formed between the fifth decelerating barrier 361 and the sixth decelerating barrier 362, and the liquid crystal 37 flows in the narrow channel to slow down the flowing speed, thereby being helpful to block the liquid crystal 37 from flowing to the position of the sealant 33. In addition, in the display panel provided in the embodiment of the present invention, the second blocking wall 35 is disposed between the second deceleration wall 34 and the third deceleration wall 36 to block the liquid crystal 37 and the sealant 33, so as to prevent the liquid crystal 37 and the sealant 33 from being mixed with each other, and ensure the display effect of the display panel. Specifically, a fifth accommodating chamber 45 is formed between the second blocking wall 35 and the second decelerating wall 34, the sealant 33 decelerated by the second decelerating wall 34 flows through the second decelerating wall 34 and is accommodated in the fifth accommodating chamber 45, and during the process that the sealant 33 flows to the second blocking wall 35 in the fifth accommodating chamber 45, due to the blocking of the second blocking wall 35, the sealant 33 continues to fill the part of the fifth accommodating chamber 45 which is not filled with the sealant 33 along the second blocking wall 35, so that the speed of the sealant 33 flowing to the liquid crystal 37 is further slowed down, and the sealant 33 is better prevented from flowing to the position of the liquid crystal 37. The second partition wall 35 includes a fourth sub partition wall 351, a fifth sub partition wall 352 and a sixth sub partition wall 353 sequentially arranged along the first direction X, the fourth sub partition wall 351 and the sixth sub partition wall 353 are arranged on the first substrate 21, and the fifth sub partition wall 352 is arranged on the second substrate 22, wherein the first substrate 21 may be an array substrate, and the second substrate 22 is a color film substrate, or the first substrate 21 is a color film substrate, and the second substrate 22 is an array substrate. When the first substrate 21 and the second substrate 22 are assembled to the cassette, the fifth sub-partition wall 352 is respectively in linear lap joint with the fourth sub-partition wall 351 and the sixth sub-partition wall 353, so as to perform an alignment function, thereby improving the situation of the joint dislocation of the first substrate 21 and the second substrate 22 and improving the joint precision of the first substrate 21 and the second substrate 22. A fourth accommodating cavity 44 is formed between the third accommodating sidewall 53 and the fourth accommodating sidewall 54 of the fifth sub-partition wall 352, and if a small amount of the sealant 33 overflows the fourth sub-partition wall 351, the sealant 33 can be stored in the fourth accommodating cavity 44, so as to further slow down the flowing speed of the sealant 33 to the liquid crystal 37. The frame glue 33 in the fourth accommodating cavity 44 extrudes the fourth accommodating sidewall 54 toward the sixth sub-partition wall 353, so that the fourth accommodating sidewall 54 is in close contact with the sixth sub-partition wall 353, and the frame glue 33 is blocked by the fourth accommodating sidewall 54 and the sixth sub-partition wall 353, thereby preventing the frame glue 33 from flowing to the liquid crystal 37 before curing, preventing the frame glue 33 from polluting the liquid crystal 37, and ensuring the display effect of the display panel.
