The invention relates to a stressed
liquid crystal transparent
projection screen which is composed of two transparent substrates (such as glass or acrylic or film) and a
polymer dispersion
liquid crystal layer between the two transparent substrates. The
polymer dispersion
liquid crystal layer is prepared from an
ultraviolet light cured pre-
polymer, a nematic phase liquid
crystal material and
gasket material plastic micro-spheres, wherein the
ultraviolet light cured pre-polymer is composed of a polymerizable
monomer, a
chain transfer agent and a photo-initiator; and the
mass ratio of the pre-polymer to the nematic phase liquid
crystal is 1:1. The production method of the stressed liquid
crystal transparent
projection screen is an
ultraviolet light curing process;
ultraviolet lights are used for obliquely irradiating and a polymer is directionally polymerized; and stress is timely applied to directionally arraying and fixing liquid crystal molecules, so that the product has a more transparent appearance. The stressed liquid crystal transparent
projection screen prepared by the invention has the
advantage of clear projection imaging; glass products are suitable for
solid transparent projection screens such as window showcases and the like; acrylic products are suitable for movable or suspended transparent projection screens such as exhibitions, theatre stages, karaoke and the like; and film products are suitable for portable type transparent projection screens and the application range of the film products is wider after the film products are matched with a mini-type
projector (
liquid crystal on silicon LCOS). According to the stressed liquid crystal transparent projection screen provided by the invention, audiences not only can see projected images but also can clearly see backstage scenes across the screen, so that the stressed liquid crystal transparent projection screen has a magic effect of suspending objects in the air.
