Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the existing liquid crystal display panels have poor waterproof performance in high-temperature and high-humidity environments
When the liquid crystal display panel is in a high-temperature and high-humidity environment for a long time, the water vapor in the environment can easily enter the interior of the liquid crystal display panel by invading the substrate, which will cause problems such as abnormal display and affect the performance of the liquid crystal display

Embodiment 1

[0099] This embodiment provides a display panel and a manufacturing method thereof, and the manufacturing method specifically includes:

[0100] Step 101, dissolving siloxane with reactive double bonds having the structure shown in formula (II) in distilled water to obtain an aqueous solution of siloxane with reactive double bonds, wherein the siloxane with reactive double bonds The mass percentage of alkane is 2%.

[0101] Step 102 , coating the siloxane aqueous solution obtained in step 101 on the sealant coating areas of the first substrate and the second substrate, and then heating the first substrate and the second substrate at 100° C. for 1 hour.

[0102]Step 103, mix the frame sealant SWB-73 (purchased from Sekisui Chemical Industry Co., Ltd.) and the photopolymerizable monomer having the structure shown in formula (IV) according to the mass ratio of 95:5 and put them into the defoaming The defoaming treatment was carried out in the container under the condition of avo...

Embodiment 2

[0109] This embodiment provides a display panel and a manufacturing method thereof, and the manufacturing method specifically includes:

[0110] Step 201, dissolving siloxane with reactive double bonds having the structure shown in formula (II) in distilled water to obtain an aqueous solution of siloxane with reactive double bonds, wherein the siloxane with reactive double bonds The mass percentage of alkane is 3%.

[0111] Step 202 , coating the siloxane aqueous solution obtained in step 201 on the sealant coated areas of the first substrate and the second substrate, and then heating the first substrate and the second substrate at 100° C. for 1.5 hours.

[0112] Step 203, mix the frame sealant SUR-66 (purchased from Sekisui Chemical Industry Co., Ltd.) and the photopolymerizable monomer having the structure shown in formula (IV) according to the mass ratio of 97:3 and put them into the defoaming The defoaming treatment was carried out in the container under the condition of ...

Embodiment 3

[0118] This embodiment provides a display panel and its manufacturing method, wherein the manufacturing method differs from Embodiment 1 in that:

[0119] The mass percentage of siloxane with reactive double bonds is 1%;

[0120] After coating the siloxane aqueous solution on the sealant-coated areas of the first substrate and the second substrate, heating the first substrate and the second substrate at 100° C. for 2 hours;

[0121] In the mixture of the frame sealant and the photopolymerizable monomer, the mass ratio of the frame sealant to the photopolymerizable monomer is 97:3.

[0122] According to the test method of Example 1, the high-temperature and high-humidity reliability test of the display panel obtained in this example is carried out, and the test results are the same as those of Example 1.

Abstract

The invention discloses a display panel, a manufacturing method thereof, and a display device, and belongs to the field of display technology. Wherein the display panel includes a first substrate and a second substrate that are sealed by a sealant, and a super-hydrophobic layer is arranged between the first substrate and the sealant, and / or, between the second substrate and the sealant A super-hydrophobic layer is arranged between the sealants; the super-hydrophobic layer is formed by reacting siloxane with reactive double bonds and photopolymerizable monomers under light conditions. The setting of the super-hydrophobic layer can effectively prevent water vapor from entering the interior of the display panel, improve the waterproof performance of the display panel, and enable the display panel to still work normally when it is in a high-temperature and high-humidity environment for a long time.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the rapid development of display technology, liquid crystal displays are widely used due to their lightness, thinness, and good display effect. [0003] The liquid crystal display panel is an important part of the liquid crystal display, and the performance of the liquid crystal display panel will affect the performance of the liquid crystal display. The liquid crystal display panel includes two substrates bonded by a frame sealant, the surface of the substrates is glass, and the frame sealant is in direct contact with the surface of the substrates. When manufacturing liquid crystal display panels, the sealant is directly coated on the sealant coating area on the surface of one of the substrates, and the liquid crystal is dripped on the surface of the other substrat...
