Description

Transparent optical device

The present invention relates to a transparent optical device, and more particularly to a transparent optical device in which a polymer dispersed liquid crystal structure layer is combined with an electrochromic structural layer.

A conventional polymer dispersed liquid crystal (PDLC), which is uniformly distributed in a polymer by using an anisotropic liquid crystal droplet. Typically, a positive-isomeric liquid crystal is uniformly dispersed in an environmental polymer under normal conditions. In the meantime, each of the anisotropic liquid crystal droplets has no specific orientation distribution. At this time, the light transmitted through the anisotropic liquid crystal droplets cannot be matched with the refractive index of the environmental polymer, and the incident light is exposed to many interfaces, and the light is heavily scattered. The light transmittance is low. If a specific electric field is provided by the formation of the electric field, the positively-isolated liquid crystal droplets are arranged along the electric field. At this time, the light passing through the positive-isomeric liquid crystal can be in the same direction as the environmental polymer. Matching, most of the light can penetrate in the forward direction, and the light transmittance is improved. By this principle, the PDLC is encapsulated in a transparent substrate such as conductive glass, and the transparent substrate is made transparent or opaque by using a change in electric field (switch). The effect of the market is often referred to as the Smart (Smart) window. For example, it is applied to the intelligent shading control of green energy building materials such as outdoor windows or the optical transmission control required for indoor privacy.

In addition, in recent years, an electrochromic (EC) component refers to the use of a reducible substance and an oxidizable substance as a pair of redox species, both of which are colorless or only a few colors, under the influence of voltage, One of the substances is reduced and the other is oxidized, at least one becomes colored, and when the voltage is turned off, the original redox species are formed again, causing the color to disappear or become light. The electrochromic material can be a liquid, a gel or a polymer. It can be packaged by two conductive substrates (which can be transparent or opaque) to provide a voltage for color change. It can be applied to doors and windows or displays or glasses, and can further be combined with induction. For example, it can take the form of a rear view mirror of a car, which can be darkened by the applied voltage during the night during the trip, thereby preventing dazzling caused by the headlights of other vehicles.

Both of the above devices have their common characteristics, and can be packaged by a transparent conductive substrate, and then a voltage is applied to perform PDLC transparency or EC color change.

Therefore, the main purpose of the creation is to integrate the polymer dispersed liquid crystal structure layer and the electrochromic structure layer to form a transparent optical device, which is integrated to provide a novel intelligent window structure, which is easy to be affixed to the building and the vehicle. Or cabinets, etc., and make the smart window for green energy use more energy-saving effect. For example, it can be applied to the exterior wall of buildings.

Strong and weak changes, but also provide a variety of light color changes.
