Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0032] The moisture permeability detection device of the film layer is provided with a moisture absorption layer in the second box, and the moisture absorption layer is formed by a polyimide electrospun sponge porous material. The polyimide electrospun sponge porous material has hydrophilic properties and can absorb water vapor. Afterwards, it expands rapidly, and has excellent performance stability in the water absorption-dehydration cycle test, and will not adhere to t...

Abstract

The invention relates to a film moisture permeability detection device and detection method. According to the film moisture permeability detection device, a moisture absorption layer made of a porous material is arranged in a second box body, and the porous material is hydrophilic, can rapidly expand after absorbing water vapor, has excellent water absorption-dehydration cycle test performance stability, cannot be adhered to the inner wall of the second box body, and ensures the accuracy of a moisture permeability detection result.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a film layer moisture permeability detection device and a method for using the film layer moisture permeability detection device to perform moisture permeability detection. Background technique [0002] PS-VA (polymer stabilized vertical alignment, polymer stabilized vertical alignment) is a technology in TFT-LCD (thin film transistor liquid crystal display). In the cell-forming process of PS-VA, it is necessary to seal the liquid crystal cell with a sealant to prevent liquid crystal overflow and water vapor intrusion, maintain the cell thickness around the liquid crystal cell, and adhere to the array substrate and color filter substrate. The main components of the frame glue are resin and some additives (such as heat curing agent, UV photoinitiator, silane coupling agent, etc.). [0003] If external water vapor enters the liquid crystal cell, it will cause short circuit of the...
