Description
Technical Field
The application relates to the technical field of display panels, in particular to a frame structure and a preparation method and application thereof.
Background
In the process of forming a PS-VA cell, a border sealant (sealant) is required to seal a liquid crystal cell, so as to prevent the overflow and the invasion of water vapor of the liquid crystal cell, maintain the thickness of the peripheral cell of the liquid crystal cell and adhere to a color film substrate of an array substrate cell.
After the array substrate and the color film substrate are assembled, the ultraviolet curing and the subsequent thermal curing are carried out, so that the complete curing of the frame adhesive is ensured, and the adhesive force of the frame adhesive is ensured. However, in the subsequent use of the panel, especially in the commercial display environment, if a certain amount of water vapor enters the box, a series of electrochemical reactions are initiated, which causes a short circuit of the circuit, a failure of the via hole, and further causes a serious problem of a horizontal gradient line.
From the molecular level, it is impossible to develop a combination of extremely high adhesion and extremely low moisture permeability, because the adhesion comes from the entropy elasticity of the polymer chain, which is directly related to the crosslinking density and the flexibility of the polymer chain, but the diffusion and permeability of small molecules such as water vapor in the crosslinked polymer are strongly related to the fluid state of the polymer, and the correlation between the crosslinking density and the flexibility of the polymer chain is very small. That is, the water-blocking performance and the adhesion performance of the frame adhesive are in a trade-off relationship, and it is difficult to achieve both high water-blocking performance and high adhesion performance by adjusting the frame formulation.
With the overall development speed of the TFT-L CD industry to "high-generation lines, large-size, narrow frames" becoming faster and faster, the commercial display product occupation ratio is increasing, so that the requirement of the frame glue to have low moisture permeability is urgent and necessary on the premise of ensuring high adhesion.
