Problems solved by technology

[0006] The embodiment of the present application provides a film layer moisture permeability detection device and a film layer moisture permeability detection method of a liquid crystal substrate, which can improve the accuracy of the moisture permeability detection result. The traditional desiccant used in the device is agglomerated to prevent the non-agglomerated desiccant from absorbing water, resulting in inaccurate measurement, the agglomerated desiccant is attached to the drying dish, which causes corrosion of the drying dish and is difficult to clean, and the agglomerated desiccant cannot be repeated The problem of using easy to pollute the environment

Abstract

The embodiment of the invention discloses a device and a method for detecting moisture permeability of a film layer of a liquid crystal substrate. The device for detecting the moisture permeability of the film layer comprises a test cavity and a water absorption layer. The test cavity comprises an upper cavity and a lower cavity; the water absorption layer is arranged in the test cavity and is positioned above the lower cavity; and the water absorption layer is made of an organic metal framework material with water absorption. According to the invention, the accuracy of a moisture permeability detection result can be improved, and the water absorption layer is easy to clean and can be recycled.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a device for detecting moisture permeability of a film layer of a liquid crystal substrate and a method for detecting the moisture permeability of a film layer of a liquid crystal substrate. Background technique [0002] Polymer stabilized vertical alignment (polymer stabilized vertical alignment, PS-VA) is a technology of thin film transistor liquid crystal display (Thin film transistor liquid crystal display, TFT-LCD). In the PS-VA cell manufacturing process, it is necessary to seal the liquid crystal cell with frame glue to prevent liquid crystal overflow and water vapor intrusion, maintain the thickness of the peripheral cell of the liquid crystal cell, and adhere to the array substrate and color filter substrate. Its main components are resin and some additives (such as thermal curing agent, ultraviolet photoinitiator, silane coupling agent, etc.). [0003] A...
