Dimmable glass structure and preparation method thereof, liquid crystal display device

Abstract

The invention discloses a dimming glass structure, a making method thereof and a liquid crystal display device, and belongs to the field of display. The dimming glass structure comprises two oppositeglass substrates, transparent electrode layers, transparent alignment layers, liquid crystal molecules and light-absorbing ions, wherein the transparent electrode layers are arranged on the inner sides of the glass substrates, the transparent alignment layers are arranged on the inner sides of the electrode layers, the liquid crystal molecules are arranged between the two alignment layers in the direction parallel to the electrode layers, and the light-absorbing ions and the liquid crystal molecules act under the acting force among the molecules. When no voltage is applied between the two electrode layers, the light-absorbing ions are also arrayed in the direction parallel to the electrode layers under the acting force among the liquid crystal molecules to absorb light; when voltage is applied between the two electrode layers, the liquid crystal molecules are arrayed in the direction perpendicular to the electrode layers, and the light-absorbing ions are irregularly dispersed between the two alignment layers. The dimming glass structure is good in light-absorbing effect, low in transmittance, high in contrast ratio and good in display effect in a dark state, and is high in light transmittance in a bright state.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light-adjustable glass structure, a preparation method thereof, and a liquid crystal display device. Background technique [0002] Dimmable glass is a kind of glass that realizes switching between the bright state and the dark state of the glass by means of electric control, temperature control, light control, or voltage control. Among them, electronically controlled dimming glass is widely used. By controlling whether the dimming glass is energized, it can switch between the bright state and the dark state. [0003] The related technology provides a dimming glass structure, the dimming glass structure includes: two glass substrates arranged oppositely, an electrode layer arranged inside the glass substrate, an alignment layer arranged inside the electrode layer, and an alignment layer arranged on the two alignment layers. Between the polymer dispersed liquid crystal (polymer...

AI Technical Summary

Problems solved by technology

[0005] There is no polarizer in the switchable glass structure provided by the related art, and in the dark state, the transmittance is high (transmittance 4% to 6%), and the contrast is low. The transmittance can be reduced by increasing the thickness of the PDLC layer , but increases the production cost

Moreover, since PDLC includes polymers, the transmittance of the dimming glass structure in the bright state is low (the transmittance is 70% to 80%), the see-through effect is poor, and the image is blurred. By increasing the applied voltage, the transmittance can be improved. transmittance, but increases the cost of use
