Displayer using ferroelectric liquid crystals

Abstract

The invention discloses a displayer using ferroelectric liquid crystals. The displayer using ferroelectric liquid crystals comprises a backlight module, a first substrate, a plurality of long-strip-shaped first electrodes, a second substrate, a liquid crystal layer and a deflection layer. Light emitted by the backlight module deflect relative to the surface of the backlight module. The first substrate is arranged on the backlight module, and a first polarizing plate is arranged on the upper side face of the first substrate. The long-strip-shaped first electrodes are parallel with one another and arranged on the first substrate in a coplanar mode. The second substrate is arranged on the first substrate and the first electrodes, a second polarizing plate is arranged on the lower side face of the second substrate, and the absorption axis of the first polarizing plate and the absorption axis of the second polarizing plate are perpendicular to each other. The liquid crystal layer is composed of the ferroelectric liquid crystals and arranged between the first substrate and the second substrate, and the ferroelectric liquid crystals are perpendicularly arranged on the first substrate in a matched mode. The deflection layer is arranged on the second substrate and used for deflecting the light which is emitted by the backlight module and affected by the liquid crystal layer to the direction perpendicular to the surface of the second substrate.

Description

technical field [0001] The invention relates to a liquid crystal display technology, in particular to a display using ferroelectric liquid crystal. Background technique [0002] Ferroelectric liquid crystal (FLC) has been gradually applied in the technical field of liquid crystal display due to its characteristics such as wide viewing angle display and fast response speed. The laminar direction of the vertically aligned ferroelectric liquid crystal is parallel to the substrate surface, and its molecular movement direction is a cone mode, which can only move or distribute within its virtual cone. The chiral center of the ferroelectric liquid crystal molecule generates a polarization field of permanent dipole moment due to the uneven distribution of electron cloud density. The direction of this polarization field is called spontaneous polarization (spontaneous polarization) vector , which is perpendicular to the inclined plane of the liquid crystal molecules; when an electric...

AI Technical Summary

Problems solved by technology

[0003] Most of the current vertical alignment ferroelectric liquid crystal displays are driven by horizontal voltage. The reason is that the tilt of liquid crystal molecules is limited by the virtual cone angle and cannot completely lie on the horizontal plane of the substrate, and the distribution of the horizontal electric field received by liquid crystal molecules is not uniform. , both lead to the problem that the bright state transmittance of the display element is not high or the driving voltage is too high
