Problems solved by technology

[0005] The optical properties of the PDLC film largely depend on the characteristics of the liquid crystal molecules themselves. Due to certain defects in the physical properties of the negative liquid crystal, the trans PDLC film prepared by using the negative liquid crystal has high driving voltage and low contrast. shortcoming

Embodiment Construction

[0046] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0047] The embodiment of the present invention aims at the problem that the trans PDLC film prepared by using negative liquid crystal has the disadvantages of high driving voltage and low contrast in the prior art, and provides a liquid crystal panel, a manufacturing method thereof, and a display device, which can reduce the trans PDLC film. The driving voltage of the PDLC film increases the contrast of the trans PDLC film.

[0048] An embodiment of the present invention provides a liquid crystal panel, including a first substrate and a second substrate oppositely arranged, and a PDLC layer arranged between the first substrate and the second substrate, wherein the PDLC layer is composed of positive liquid crystal and The polymer matrix...

Abstract

The invention provides a liquid crystal panel, a manufacturing method thereof, and a display device, which belong to the technical field of liquid crystal display. The liquid crystal panel includes a first substrate, a second substrate and a PDLC layer that are arranged oppositely, and a first transparent electrode unit connected to the TFT that is arranged on the side of the first substrate facing the second substrate; and is arranged on the side of the second substrate facing the first substrate The second transparent electrode unit connected to the first voltage; the third transparent electrode unit arranged on the first substrate and the second substrate and having a preset height connected to the second voltage, the second voltage and the pole of the first voltage opposite polarity; when powered on, the first transparent electrode unit and the second transparent electrode unit have the same polarity and are opposite to the polarity of the third transparent electrode unit; when powered off, the liquid crystal molecules of the PDLC layer are arranged vertically to the substrate . The invention can reduce the driving voltage of the trans PDLC film and improve the contrast of the trans PDLC film.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal panel, a manufacturing method thereof, and a display device. Background technique [0002] PDLC (polymer dispersed liquid crystal, polymer dispersed liquid crystal) is one of the liquid crystal units used in LCD (Liquid Crystal Display, liquid crystal display), which has the characteristics of light scattering intensity to control light transmission and does not require polarizing plates. The optical properties of the PDLC film largely depend on the effective refractive index of the liquid crystal molecules and the matching with the polymer matrix. [0003] Ordinary PDLC films prepared by using positive liquid crystals, when no voltage is applied, the liquid crystal molecules are arranged in disorder, so after the incident light enters, refraction and reflection occur many times at the interface between the liquid crystal molecules and the polymer ...
