Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that the prior art has at least the following problems: the glass fiber and gold ball particles have poor compatibility with other components in the sealant, so that the glass fiber and gold ball particles cannot be used in the sealant. Uniform dispersion in the frame sealant leads to different supporting forces at different parts of the frame sealant, resulting in gap defects. The liquid crystal molecules located between the array substrate and the color filter substrate easily penetrate the sealant and puncture, which affects the display effect of the LCD panel.

preparation example Construction

[0061] In a fourth aspect, an embodiment of the present invention provides a method for preparing a liquid crystal panel, the method comprising the following steps:

[0062] Step 1, uniformly mixing the frame sealing glue matrix and graphene oxide to obtain a mixture;

[0063] Step 2, the mixture is subjected to defoaming treatment under light-proof conditions;

[0064] Step 3, coating the degassed mixture obtained in step 2 on the frame of the color filter substrate;

[0065] In step 4, the array substrate dripped with liquid crystal and the color filter substrate obtained in step 3 are boxed together, and the liquid crystal panel is obtained after ultraviolet polymerization and thermal polymerization.

[0066] In this preparation method, the sealant used to bond the array substrate and the color filter substrate is a sealant containing graphene oxide. Graphene oxide not only has good support and conductivity, but also has good barrier properties, and It has good compatibil...

Abstract

The present disclosure discloses a sealing agent, a liquid crystal panel, a liquid crystal display device, and a fabricating method thereof. The sealing agent comprises a sealing agent matrix and graphene oxide. The graphene oxide not only functions to support substrates and enable electrical conduction, but also effectively prevents the phenomenon of liquid crystal molecules penetration from occurring. In this way, a liquid crystal panel which is prepared with the sealing agent as a bonding agent has excellent display effect.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a frame sealing glue, a liquid crystal panel, a liquid crystal display and a preparation method. Background technique [0002] With the advancement of science and technology, liquid crystal panels have gradually become one of the fastest-growing display devices due to their lightness and thinness. The liquid crystal panel is formed by an array substrate and a color filter substrate. The sealant is used as an adhesive to bond the array substrate and the color filter substrate together. [0003] see figure 1 , the commonly used frame sealant mainly includes: frame sealant base 2 and additives for supporting and conducting. Among them, the sealing glue matrix 2 mainly includes components such as photocurable resin, thermosetting resin, photoinitiator, thermosetting agent, organic filler and coupling agent; the additive mainly includes glass fiber (not shown in the ...
