Problems solved by technology

However, in the process of mixing glass fiber and gold ball particles, it is inevitable that there will be uneven mixing, resulting in different supporting forces at different parts, resulting in peripheral gap defects, and liquid crystal molecules are easy to penetrate through the sealant, causing punctures, which in turn affects the liquid crystal display panel. The display effect of

Embodiment 1

[0039] This embodiment provides a method for preparing a frame sealant composition, including:

[0040] The barrier material and the collagen solution for sealing the frame are mixed according to a preset mass percentage to obtain a mixture;

[0041] The mixture is subjected to light-shielding degassing treatment to obtain a frame sealing glue composition.

[0042] In this embodiment, a barrier material is doped into the frame-sealing collagen solution to prepare a frame-sealing glue composition. The barrier material has good barrier properties, which can effectively prevent liquid crystal molecules from penetrating the frame sealant, and can also prevent pollution caused by the penetration of small molecules in the frame sealant, thereby improving the puncture resistance of the frame sealant composition, thereby improving performance of LCD panels.

[0043] Preferably, the barrier material is a high density polyethylene / polyamide (HDPE / PA) composite. Among them, HDPE is a ...

Embodiment 2

[0056] This embodiment provides a frame sealant composition, which is prepared by the above-mentioned preparation method, and the frame sealant composition includes a frame sealant and a barrier material mixed in the frame sealant.

[0057] The frame sealant composition of this embodiment is doped with a barrier material. The barrier material has good barrier properties, can effectively prevent liquid crystal molecules from penetrating the frame sealant, and can also prevent small molecules in the frame sealant from penetrating. contamination, thereby improving the puncture resistance of the frame sealant composition, thereby improving the performance of the liquid crystal display panel.

[0058] Preferably, the barrier material is HDPE / PA composite material. Among them, HDPE is a non-polar polymer, which has good barrier properties to polar solvents such as water, but has high permeability to non-polar organic solvents and gases; and PA is a polar polymer, which has good barr...

Embodiment 3

[0063] This embodiment provides a method for manufacturing a display panel. The display panel includes a first substrate and a second substrate arranged on a cell. The preparation method includes:

[0064] Step c: coating the above-mentioned frame sealant composition on the frame sealant coating area of ​​the first substrate;

[0065] Specifically, the display panel may be a liquid crystal display panel, and the display panel further includes: a liquid crystal cell located between the first substrate and the second substrate.

[0066] Usually, the first substrate is a color film substrate. When coating the frame sealant composition on the color film substrate, use a light-proof operation to prevent the sealant mixture from being cured when it is irradiated by light. When forming the composition, the frame sealant composition is evenly coated on the frame sealant coating area of ​​the color filter substrate.

[0067] Step d: boxing the second substrate and the first substrate ...

Abstract

The invention provides a frame sealing adhesive composition, a display panel, a preparation method and a display device, and belongs to the technical field of display, wherein the preparation method of the frame sealing adhesive composition comprises the steps of mixing a barrier material and a primary liquid of a frame sealing adhesive according to the preset mass percent to obtain a mixture, keeping the mixture out of the sun, and defoaming the mixture to obtain the frame sealing adhesive composition. According to the technical scheme, the puncture protection capability of the frame sealing adhesive composition is improved, so that the performance of the liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a frame sealing adhesive composition, a display panel, a preparation method, and a display device. Background technique [0002] With the advancement of technology, liquid crystal display panels have gradually become one of the fastest-growing display devices due to their lightness and thinness. The manufacturing process of the liquid crystal display panel will directly affect the brightness, contrast, color and other properties of the final product. [0003] Existing liquid crystal display panels are generally formed by boxing an array substrate and a color filter substrate, and using a sealant as an adhesive to bond the two together to form a complete liquid crystal display panel. Glass fiber and gold ball particles are generally added to the frame sealant to support and connect the upper and lower substrates respectively. However, in the process of mixing glass fiber and go...
