AI Technical Summary

Technical Problem

Conventional LCD panel manufacturing processes are complex, prone to defects, and require multiple high-temperature baking steps, leading to substrate deformation and distortion, while also necessitating multi-layer structures with electrodes and alignment films.

Method used

The electro-optical element employs two substrates with alignment conductive layers formed by coating a conductive mixture of polymers, adhesives, and crosslinking agents, which are then baked and brushed to align trenches, replacing the need for separate conductive and alignment films, and a liquid crystal layer is inserted between these layers.

Benefits of technology

This simplifies the manufacturing process, reduces defects, and enhances optical performance by improving alignment and conductivity, resulting in higher light transmittance and reflection efficiency.

Abstract

An electrically controlled optical component is provided to solve the problems of multi-layer structure and complicated manufacturing process of conventional liquid crystal panel. The electrically controlled optical component includes two substrates facing each other in parallel, and a liquid crystal layer. The two substrates each have an alignment conductive layer located on the opposite inner surfaces of the two substrates. The two alignment conductive layers are electrically connected to a voltage source respectively to form a switchable electric field between the two alignment conductive layers. The surfaces of the two alignment conductive layers facing inwards form alignment structures. The material of each alignment conductive layer includes a conductive macromolecule, an adhesive, and a cross-linking agent. The liquid crystal layer is a liquid crystal material located between the two substrates. The upper and lower surfaces of the liquid crystal layer are respectively in contact with the two alignment conductive layers. The invention further discloses a method for manufacturing the electrically controlled optical component. The electrically controlled optical component provides the effect of simplifying structure and process.
