Manufacturing method of liquid crystal phase shifter and liquid crystal phase shifter

Abstract

The invention discloses a method for manufacturing a liquid crystal phase shifter and the liquid crystal phase shifter and belongs to the technical field of electronics. The method includes the stepsof acquiring a phase shifter housing; injecting a liquid crystal in which a photocurable material is dissolved into the phase shifter housing through a notch; using a preset mask plate as a mask and exposing the liquid crystal in which the photocurable material is dissolved from the outer sides of transparent substrate base plates to form a stereoscopic network-shaped supporting structure which isin contact with the two substrate base plates; discharging the remaining liquid crystal in which the photocurable material is dissolved in the phase shifter housing; injecting a functional liquid crystal into the phase shifter housing through the notch. Firstly, the liquid crystal in which the photocurable material is dissolved is injected into a phase shifter housing, and then the supporting structure is formed by exposing the liquid crystal in which the photocurable material is dissolved, and finally, the supporting structure maintains the box thickness of the phase shifter, so that friction between the liquid crystal and the substrate base plates is avoided, and the problem that the service life of liquid crystal phase shifters in related technologies is low can be solved. The effect of improving the service life of the liquid crystal phase shifter is achieved.

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that there are at least the following problems in related technologies: when the liquid crystal in the area of ​​the liquid crystal layer away from the sealant structure is deformed, the thickness of the liquid crystal phase shifter may still change, while the thickness of the liquid crystal phase shifter When the change occurs, the liquid crystal in the liquid crystal layer will rub against the substrate substrate, which may cause the life of the liquid crystal phase shifter to be low
