The present disclosure is directed to the technical problem of the display panel and the display device of the prior art that the frame is susceptible to lateral stress during the falling process, which causes the screen to be damaged. This embodiment can solve the defect.

Example one

As shown in FIG. 1, the display panel 10 provided by the present disclosure includes:

A first substrate 1 and a second substrate 2 disposed oppositely;

The sealant 3 is arranged in the peripheral area between the first substrate 1 and the second substrate 2 for sealing the first substrate 1 and the second substrate 2; and

A plurality of supporting parts 4 are arranged in the frame sealing glue 3 in sequence, one end of each supporting part 4 is in sealing contact with the second substrate, and the other end of the supporting part is covered by the frame sealing glue 3 Covered.

It should be noted that the display panel 10 may be a liquid crystal display panel. When the display panel 10 is a liquid crystal display panel, the first substrate 1 is an array substrate, and the display area of the first substrate 1 is provided with A thin film transistor layer, and a first flat layer 61 and a first alignment layer 71 sequentially disposed above the thin film transistor layer. The second substrate 2 is a color film substrate, and black is sequentially disposed on the second substrate 2 The matrix 5, the second flat layer 62 and the second alignment layer 72 are filled with liquid crystal 8 between the first substrate 1 and the second substrate 2; at the same time, on the first substrate 1 and the second substrate 2 The peripheral area of the second substrate 2 is provided with a sealant 3 for sealing between the first substrate 1 and the second substrate 2. The embodiment of the present disclosure is described with an example in which the display panel 10 is a liquid crystal display panel.

Specifically, the top end 42 of the support portion 4 is in contact with the second flat layer 62 provided on the second substrate 2, and the bottom end 41 of the support portion 4 is located on the first substrate 1. And the bottom end 41 of the supporting portion 4 is not in contact with the side of the first substrate 1 close to the frame sealant 3, wherein the top end 42 of the supporting portion 4 is the supporting portion 4 is close to an end of the second substrate 2, and the bottom end 41 of the supporting portion 4 is an end of the supporting portion 4 close to the first substrate 1. That is to say, the height of the supporting portion 4 is smaller than the thickness of the frame sealant 3. Since the first substrate 1 is an array substrate, the first substrate 1 is provided with a thin film transistor array layer. The purpose is to prevent the bottom end 41 of the supporting portion 4 from colliding with the first substrate 1 when the display panel 10 is dropped, causing damage to the first substrate 1, and at the same time, it can also improve The adhesion area between the frame sealing glue 3 and the first substrate 1 improves the adhesion between the frame sealing glue 3 and the first substrate 1, thereby increasing the adhesion between the first substrate 1 and the first substrate 1 The adhesion effect between the second substrate 2 is described.

Since the shape of the display panel 10 is generally rectangular, the frame sealing glue 3 is generally arranged in a lip shape in the peripheral area of the display panel 10. Accordingly, the supporting portion 4 is arranged in the frame sealing glue 3 The area is also arranged in a lip shape, which can buffer the lateral stress received around the display panel 10. Therefore, regardless of the drop angle of the display panel 10, the support 4 can play a The effect of reducing the damage degree of the screen of the display panel 10.

The number of the support portion 4 may be one or multiple, wherein the number of the support portion 4 is determined according to the width of the frame sealant 3 coated on the display panel 10, for example, When the width of the frame sealant 3 coated on the display panel 10 is larger, the number of the support portions 4 is greater; when the width of the frame sealant 3 coated on the display panel 10 is smaller , The number of the supporting parts 4 is small. Generally, since the width of the frame sealant 3 is 400~600um, the number of the supporting parts 4 can be set to 1~5, so that the supporting parts 4 can satisfy the maximum buffering effect while at the same time. The arrangement of the supporting parts 4 in the frame sealing glue 3 should not be too dense, so as to prevent the supporting parts 4 from occupying too much space of the frame sealing glue 3 and affecting the first substrate 1 and the second substrate 1 The adhesion effect of the second substrate 2.

When the number of the support portions 4 is multiple, when the display panel 10 falls, the display panel 10 is subjected to a greater lateral stress. Therefore, in order to make the lateral stress received by each support portion 4 more uniform , So that the lateral stress on each position of the display panel 10 is more uniform, and the separation distance between two adjacent support portions 4 can be kept equal. Specifically, every two adjacent support portions 4 The distance between them is 50~100um. At the same time, the widths of two adjacent supporting portions 4 can be kept equal, and the heights of two adjacent supporting portions 4 can be kept equal. Generally, the width of the support part 4 is 10-20 um, and the height of the support part 4 is 5-15 um.

The material selected for the support portion 4 is not particularly limited. Optionally, the material selected for the support portion 4 is polystyrene (PS), because the PS material is a highly crystalline polymer with excellent performance. Material/gas composite material, with its unique and superior performance, has become the fastest growing environmental protection new type of pressure-resistant cushioning and thermal insulation material. It can be made into foam products of different densities and shapes, and can be produced in various thicknesses. When the display panel 10 is dropped, the support portion 4 has a certain buffer capacity for the lateral stress received by the display panel 10, thereby weakening the impact force received by the display panel 10 to reduce The probability that the screen of the display panel 10 is broken.

Similarly, FIG. 2A, FIG. 2B, and FIG. 2C are schematic diagrams of the cross-sectional structure of the display panel in FIG. 1 along the A-A direction. Since the PS material has a certain degree of plasticity, the specific shape of the supporting portion 4 is not particularly limited. Optionally, the cross-sectional shape of the supporting portion 4 is a waveform, for example, as shown in FIG. 2A The cross-sectional shape of the support part 4 is a square wave; the cross-sectional shape of the support part 4 as shown in FIG. 2B is a broken line shape; the cross-sectional shape of the support part 4 as shown in FIG. 2C is a wave shape.

Further, the area of the support portion 4 whose cross-sectional shape is a wave is larger than the area of the support portion 4 whose cross-sectional shape is a linear shape. Specifically, the area of the support portion 4 whose cross-sectional shape is a waveform is a cross-sectional area. The area of the support portion 4 with a linear shape is 1.2 to 2 times. When the display panel 10 is dropped, the cushioning capacity of the support portion 4 to the display panel 10 can be increased, thereby further improving the The impact resistance of the display panel 10 further improves the service life of the display panel 10.

It should be noted that, in the embodiment of the present disclosure, the number, width, height, material of the supporting parts 4 and the separation distance between two adjacent supporting parts 4 are not specifically limited. The number, width, height, material of the parts 4 and the separation distance between two adjacent support parts 4 need to be determined according to actual conditions, and the embodiments of the present disclosure should not be limited by this.
