[0029] The present application will be described in detail below with reference to the accompanying drawings and optional embodiments.

[0030] Figure 1 is a schematic diagram of a display device according to an embodiment of the present application, as Figure 1 shown, the display device 10 includes a backlight module 20 and a display panel 30. The backlight module 20 provides light sources for the display panel 30. The display panel 30 includes an opposing substrate 40, a liquid crystal layer 60, and an array substrate 50. The opposing substrate 40 is disposed opposite to the array substrate 50, and the liquid crystal layer 60 is disposed between the opposing substrate 40 and the array substrate 50.

[0031] The backlight module 20 includes a backplane 21, a backlight source 22, and a rubber frame 23. The backlight source 22 is disposed on the backplane 21 and is located between the display panel 30 and the backplane 21. The rubber frame 23 is disposed on the backplane 21 to support the display panel 30. The display panel 30 and the rubber frame 23 can be fixedly connected by adhesive.

[0032] The backlight source 22 can be a direct-lit backlight source 22 or an edge-lit backlight source 22, which is not limited herein. The driving chip 530 of the present application is bonded to the array substrate 50.

[0033] The present application also discloses an array substrate 50 and improves the array substrate 50, which can be used in the display device 10 described above. For the array substrate 50 of the present application, the following embodiments are listed for explanation, and the specific design is as follows:

[0034] Embodiment 1:

[0035] Figure 2 is a schematic diagram of a display device according to the first embodiment of the present application, as Figure 1 and Figure 2As shown, the array substrate 50 includes a substrate 500, an active switch layer 550, and a driving chip 530. The active switch layer 550 is disposed on the substrate 500. The active switch layer 550 includes a bonding area. The driving chip 530 is bonded to the side of the active switch layer 550 facing away from the substrate 500 and is located within the bonding area. A conductive adhesive 540 is further disposed between the driving chip 530 and the substrate 500.

[0036] The array substrate 50 further includes a correction structure 600. The correction structure 600 is closely attached to the side of the substrate 500 away from the driving chip 530, and the orthographic projection of the correction structure 600 on the substrate 500 covers the orthographic projection of the driving chip 530 on the substrate 500.

[0037] Preferably, the orthographic projection of the correction structure 600 on the substrate 500 is larger than the orthographic projection of the driving chip 530 on the substrate 500, and the expansion rate of the correction structure 600 is smaller than the expansion rate of the substrate 500. Under the same conditions, the correction structure 600 is less likely to deform relative to the substrate 500.

[0038] By adding a correction structure 600 and disposing it on the side of the substrate 500 away from the driving chip 530, and the orthographic projection of the correction structure 600 on the substrate 500 covers the orthographic projection of the driving chip 530 on the substrate 500, and making the correction structure 600 closely attached to the side of the substrate 500 facing away from the driving chip 530, and the expansion rate of the correction structure 600 is smaller than the expansion rate of the substrate 500, the phenomenon of the substrate 500 bending is avoided. Even after the substrate 500 is bent, the correction structure 600 can also make the substrate 500 recover from deformation, improving the display effect of the display panel 30.

[0039] The correction structure 600 can be closely attached to the substrate 500 by means of adhesion or by means of mutual abutment. In this embodiment, the correction structure 600 is closely attached to the substrate 500 by means of adhesion, specifically as follows:

[0040] The correction structure 600 includes a fixing portion 610, a supporting portion 620, and an adhesive portion 630. The fixing portion 610 is disposed on the side of the substrate 500 facing away from the driving chip 530. The supporting portion 620 is disposed between the fixing portion 610 and the substrate 500, and both sides are respectively in contact with the fixing portion 610 and the substrate 500.

[0041] The bonding portion 630 is disposed between the fixing portion 610 and the substrate 500, and the supporting portion 620 and the bonding portion 630 are disposed on the same layer and have the same thickness. The bonding portion 630 is disposed around the periphery of the supporting portion 620 to bond the fixing portion 610 and the substrate 500. The projection of the supporting portion 620 on the substrate 500 covers the projection of the driving chip 530 on the substrate 500.

[0042] The material of the supporting portion 620 in this embodiment may be a rubber block that is not easily deformed, or other metal materials with relatively high hardness. The bonding portion 630 has strong adhesiveness. The supporting portion 620 applies an upward thrust to the substrate 500 corresponding to the driving chip 530, and the bonding portion 630 around the supporting portion 620 applies a downward pulling force to the substrate 500 around the supporting portion 620, thereby preventing the substrate 500 from bending upward. Moreover, even after the substrate 500 bends upward, a force opposite to the deformation can be applied to the substrate 500 to cause the substrate 500 to recover from the deformation.

[0043] The glue frames 23 are disposed around the periphery of the array substrate 50, and the glue frames 23 are attached to the side of the array substrate 50 facing away from the counter substrate 40. The fixing portion 610 may also directly adopt the glue frame 23, that is, the supporting portion 620 and the bonding portion 630 are directly disposed on the glue frame 23, so that the fixing portion 610 can be omitted, saving costs; and it can also prevent the problem of light leakage between the array substrate 50 and the glue frame 23 caused by the uneven surface at the connection between the array substrate 50 and the glue frame 23.

[0044] Embodiment 2:

[0045] Figure 3 is a schematic diagram of a first display device according to a second embodiment of the present application. As Figure 3 shown, different from the first embodiment, in this embodiment, the calibration structure 600 and the substrate 500 are closely attached by shape matching.

[0046] The calibration structure 600 in this embodiment includes a calibration main body portion 710 and at least two first abutting structures 720. The two first abutting structures 720 are respectively located at two ends of the calibration structure 600, and both of the two first abutting structures 720 are disposed on the side of the calibration main body portion 710 close to the substrate 500.

[0047] The substrate 500 includes a substrate main body portion 510 and at least two second abutting structures 520. The two second abutting structures 520 are both disposed on the side of the substrate main body portion 510 close to the calibration structure 600, and the second abutting structures 520 and the first abutting structures 720 are arranged in one-to-one correspondence;

[0048] The first abutting structure 720 abuts against the second abutting structure 520, thereby realizing the connection that the calibration structure 600 is closely attached to the substrate 500.

[0049] The shape of the first abutting structure 720 includes a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, etc. Hereinafter, the case where the shape of the first abutting structure 720 is a triangular prism will be taken as an example for explanation.

[0050] The shape of the first abutting structure 720 is a triangular prism, including a first surface 721, a second surface 722, and a third surface 723 that are connected in sequence. The third surface 723 is on the same plane as the surface of the calibration main body 710 close to the substrate 500. The projection of the connection line between the first surface 721 and the second surface 722 on the calibration main body 710 does not overlap with the third surface 723. That is, it can be understood that the first abutting structure 720 is an inclined triangular prism. The cross-section of the first abutting structure 720 is an obtuse triangle, and the included angle between the first surface 721 and the third surface 723 is an obtuse angle.

[0051] The shape of the second abutting structure 520 is a triangular prism, including a fourth surface 524, a fifth surface 525, and a sixth surface 526 that are connected in sequence. The sixth surface 526 is on the same plane as the surface of the substrate main body 510 close to the calibration structure 600. The projection of the connection line between the fourth surface 524 and the fifth surface 525 on the substrate main body 510 does not overlap with the sixth surface 526. That is, it can be understood that the second abutting structure 520 is an inclined triangular prism. The cross-section of the second abutting structure 520 is an obtuse triangle, and the included angle between the fifth surface 525 and the sixth surface 526 is an obtuse angle.

[0052] The first surface 721 abuts against the fifth surface 525, which can be understood that the first abutting structure 720 is relatively inclined with respect to the corresponding second abutting structure 520, and the first abutting structure 720 abuts against the relatively inclined surface of the corresponding second abutting structure 520. Thereby, the calibration structure 600 prevents the substrate 500 from bending.

[0053] The above takes the first abutting structure 720 including two as an example. The first abutting structure 720 may also include multiple ones, and multiple first abutting structures 720 are arranged in a row, as follows:

[0054] Figure 4 It is a schematic diagram of the second display device of the second embodiment of the present application, as Figure 4As shown in the figure, the dashed line in the figure represents the axis of symmetry of the calibration main body 710, the arrow A represents the first direction, the arrow B represents the second direction, and the calibration structure 600 includes a plurality of the first abutting structures 720. The plurality of the first abutting structures 720 are divided into a plurality of first left abutting structures 724 and a plurality of first right abutting structures 725. The first left abutting structures 724 and the first right abutting structures 725 are respectively distributed on both sides of the axis of symmetry of the calibration main body 710 and are symmetrically distributed.

[0055] The first surface 721 of the first left abutting structure 724 is close to the axis of symmetry, and the second surface 722 of the first left abutting structure 724 faces away from the axis of symmetry; the first surface 721 of the first right abutting structure 725 is close to the axis of symmetry, and the second surface 722 of the first right abutting structure 725 faces away from the axis of symmetry.

[0056] The substrate 500 includes a plurality of the second abutting structures 520. The plurality of the second abutting structures 520 are divided into a plurality of second left abutting structures 527 and a plurality of second right abutting structures 528. The second left abutting structures 527 and the second right abutting structures 528 are respectively distributed on both sides of the axis of symmetry of the calibration main body 710 and are symmetrically distributed.

[0057] The fourth surface 524 of the second left abutting structure 527 is close to the axis of symmetry, and the fifth surface 525 of the second left abutting structure 527 faces away from the axis of symmetry; the fourth surface 524 of the second right abutting structure 528 is close to the axis of symmetry, and the fifth surface 525 of the second right abutting structure 528 faces away from the axis of symmetry.

[0058] The first left abutting structure 724 is disposed between two adjacent second left abutting structures 527, and the first surface 721 of the first left abutting structure 724 is in contact with the fifth surface 525 of the second left abutting structure 527, and the second surface 722 of the first left abutting structure 724 is in contact with the fourth surface 524 of another second left abutting structure 527.

[0059] The first right abutting structure 725 is disposed between two adjacent second right abutting structures 528, and the first surface 721 of the first right abutting structure 725 is in contact with the fifth surface 525 of the second right abutting structure 528, and the second surface 722 of the first left abutting structure 724 is in contact with the fourth surface 524 of another second left abutting structure 527.

[0060] When the substrate 500 is bent, the first surface 721 of the first left abutting structure 724 will apply a force in the opposite direction to the fifth surface 525 of the corresponding second left abutting structure 527; the first surface 721 of the first right abutting structure 725 will apply a force in the opposite direction to the fifth surface 525 of the corresponding second right abutting structure 528, thereby preventing the substrate 500 from bending.

[0061] The gap d1 between the first surface 721 and the fifth surface 525 is 0.05 mm, and the gap d2 between the second surface 722 and the fourth surface 524 is 0.2 mm, which can not only facilitate the assembly of the correction structure 600, but also prevent the substrate 500 from bending at a large angle.

[0062] Furthermore, the included angle range between the first surface 721 and the third surface 723 of the first left abutting structure 724 includes 95° - 115°, and the included angle range between the first surface 721 and the third surface 723 of the first right abutting structure 725 includes 95° - 115°;

[0063] The included angle range between the fifth surface 525 and the sixth surface 526 of the second left abutting structure 527 includes 95° - 115°, and the included angle range between the fifth surface 525 and the sixth surface 526 of the second right abutting structure 528 includes 95° - 115°.

[0064] Moreover, taking the direction away from the symmetry axis of the first left abutting structure 724 as the first direction, and the direction away from the symmetry axis of the first right abutting structure 725 as the second direction.

[0065] If the substrate 500 bends towards the side of the driving chip 530, then along the first direction and the second direction, the stress generated between the first left abutting structure 724 and the second left abutting structure 527 will gradually increase; the stress generated between the first right abutting structure 725 and the second right abutting structure 528 will also gradually increase.

[0066] It can be achieved that along the first direction, the included angle between the first surface 721 and the third surface 723 of the first left abutting structure 724 gradually increases; along the second direction, the included angle between the first surface 721 and the third surface 723 of the first right abutting structure 725 gradually increases.

[0067] Along the first direction, the angle between the fifth surface 525 and the sixth surface 526 of the second left abutting structure 527 gradually increases; along the second direction, the angle between the fifth surface 525 and the sixth surface 526 of the second right abutting structure 528 gradually increases. That is, the second left abutting structure 527 matches the shape of the first left abutting structure, and the second right abutting structure 528 matches the shape of the first right abutting structure 725.

[0068] Thereby, along the first direction and the second direction, the first left abutment structure 724 and the second left abutment structure 527 can be fitted more and more tightly, and the first right abutment structure 725 and the second right abutment structure 528 can be fitted more and more tightly, and the mutual forces generated between them will gradually increase, thereby offsetting the gradually increasing stress generated by the deformation of the substrate 500.

[0069] Furthermore, since the correction structure 600 is directly arranged below the driver chip 530, in order to promote the heat dissipation of the driver chip 530, the correction structure 600 can be made of porous ceramic material. This is conducive to helping the driver chip 530 to dissipate heat, and the expansion rate of the porous ceramic material is much smaller than the glass material of the substrate 500, which can also ensure that the substrate 500 is sufficiently prevented from bending and deformation. Of course, the correction structure 600 can also be made of other materials with good heat dissipation performance.

[0070] In order to prevent the correction structure 600 from protruding from the surface of the substrate 500, the present application further provides a mounting groove 529 on the substrate 500. Specifically:

[0071] like Figure 5 As shown, the mounting groove 529 is arranged on the side of the substrate 500 away from the active switch layer 550, and the second abutment structure 520 is arranged at the bottom of the mounting groove 529; the correction structure 600 is arranged corresponding to the mounting groove 529, and the side of the correction structure 600 away from the substrate 500 is flush with the side of the substrate 500 away from the active switch layer 550.

[0072] This is equivalent to embedding the correction structure 600 into the substrate 500, thereby achieving surface flatness on the side of the substrate 500 away from the active opening layer, and preventing light leakage between the array substrate 50 and the frame glue due to the uneven surface of the connection between the substrate 500 and the glue frame 23.

[0073] Embodiment 3:

[0074] Figure 6 is a schematic diagram of an array substrate according to the third embodiment of the present application. Figure 6As shown, different from the second embodiment, the first abutting structure 720 of this embodiment includes a first vertical portion 810 and a first horizontal portion 820. The first vertical portion 810 is provided on the calibration main body portion 710, and the first horizontal portion 820 is provided at one end of the first vertical portion 810 away from the calibration main body portion 710, and the first vertical portion 810 is perpendicularly arranged with the first horizontal portion 820.

[0075] The second abutting structure 520 includes a second vertical portion 910 and a second horizontal portion 920. The second vertical portion 910 is provided on the substrate main body portion 510, and the second horizontal portion 920 is provided at one end of the second vertical portion 910 away from the substrate main body portion 510, and the second vertical portion 910 is perpendicularly arranged with the second horizontal portion 920.

[0076] One surface of the first horizontal portion 820 facing the calibration main body portion 710 abuts against one surface of the second horizontal portion 920 facing the substrate 500. Thereby, the substrate 500 is prevented from initiating bending deformation. Compared with the second embodiment, the first abutting structure 720 and the corresponding second abutting structure 520 of this embodiment are hooked together, and the acting force between them is relatively large.

[0077] Embodiment 4:

[0078] Figure 7 is a schematic diagram of an array substrate according to the fourth embodiment of the present application. As Figure 7 shown, the difference between this embodiment and the second embodiment is that this embodiment does not require the first abutting structure 720 and the second abutting structure 520 to cooperate with each other. Instead, by providing a mounting groove 529 with a trapezoidal cross-section on the substrate 500 and matching the shape of the calibration structure 600, the substrate 500 is prevented from bending and deforming.

[0079] Specifically, the cross-section of the mounting groove 529 is an inverted trapezoid, and the cross-section of the calibration structure 600 is also an inverted trapezoid matching the mounting groove 529. The calibration structure 600 slides into the mounting groove 529 from the side of the substrate 500, and one surface of the calibration structure 600 close to the substrate 500 is attached to the bottom of the mounting groove 529. The side surfaces of the calibration structure 600 are respectively in contact with the groove walls of the mounting groove 529, and one surface of the substrate 500 away from the active switch layer 550 is flush with one surface of the calibration structure 600 away from the bottom of the groove.

[0080] Compared with the first embodiment, this embodiment does not need to bond the calibration structure 600 to the substrate 500 with adhesive. Compared with the second and third embodiments, the structure of this embodiment is simpler and more reliable, and the production and installation are also easier.

[0081] It should be noted that the inventive concept of this application can form a very large number of embodiments. However, due to the limited space of the application documents, it is impossible to list them all. Therefore, on the premise of non-conflict, the above-described embodiments or technical features can be arbitrarily combined to form new embodiments.

It cannot be determined that the specific implementation of this application is only limited to these descriptions. For those of ordinary skill in the technical field to which this application belongs, without departing from the concept of this application, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of this application.
