A liquid crystal phase shifter and manufacturing method thereof

Abstract

Embodiments of the present invention provide a liquid crystal phase shifter and a manufacturing method thereof, which relate to the field of liquid crystal panel manufacturing, and can make the liquid crystal phase shifter not easily deformed and have more stable performance. The liquid crystal phase shifter includes: a first substrate and a second substrate facing each other; a liquid crystal layer arranged between the first substrate and the second substrate; wherein, polymer support bodies are distributed in arrays in the liquid crystal layer. The invention is applied to the manufacture of liquid crystal phase shifters.

Description

Technical field [0001] The present invention relates to the field of production of liquid crystal panels, and more particularly to a liquid crystal phase shifter and a method of fabricating it. Background technique [0002] The phase shifter is a device that can be adjusted to the wave, and has a wide range of applications in radar, missile attitude control, accelerator, communications, instrumentation and even music. The liquid crystal phase shifter has a major advantage in continuous adjustment. Since the medium loss of microwaves is required, the liquid crystal phase shifter box is generally more than ten times higher than that of the conventional LCD thick, according to the medium loss formula, the larger the thickness, the smaller the effective dielectric constant, the medium loss, so the current The liquid crystal phase shifting box is provided to 100-300 um, which makes the liquid crystal volume in the insertion box are several times the ordinary LCD (Liquid CrystaldisPlay...

AI Technical Summary

Problems solved by technology

Due to the need to reduce the dielectric loss of microwaves, the thickness of the liquid crystal phase shifter cell is generally tens to hundreds of times thicker than that of traditional LCDs. According to the dielectric loss formula, the larger the cell thickness, the smaller the effective dielectric constant and the smaller the dielectric loss. Therefore, the current The thickness of the liquid crystal phase shifter box is 100-300um, so that the amount of liquid crystal poured into the box is tens to hundreds of times that of ordinary LCD (Liquid Crystal Display, liquid crystal display), which makes it necessary to make the liquid crystal phase shifter Thicker support. In the existing method, when making a photo spacer, the commonly used photoresist has a low viscosity, and it is difficult to achieve a thickness of more than 100um. Even if the coating is successful, the liquid crystal phase will be shifted The device is easily deformed by external force, which affects the performance of the liquid crystal phase shifter
