Easy-to-install dimming film with power supply

Abstract

The invention discloses an easy-to-install dimming film with a power supply. The dimming film comprises a packaged box, a dimming film body and a double-sided adhesive; the dimming film body is arranged in a transparent panel; an electrode is arranged outside the transparent panel; after electrification, the light transmittance can be changed according to a voltage; the transparent panel is a carrier of the dimming film body; the dimming film body is sealed in the transparent panel; the packaged box is arranged on one side of the transparent panel, and comprises a power supply system and a control module; the power supply system is electrically connected with the control module; and the power supply system is connected with the dimming film body through electrodes. Each dimming film body is provided with one packaged box, so that complex wiring connection is abandoned, and the stability of a device is improved; the dimming film body and the device box are not assembled and transported,so that the loss rate and the cost of transportation are greatly reduced; during installation, the dimming film body is connected with the packaged box in a simple clamping manner, and the dimming film body is attached through the double-sided adhesive to complete the installation, so that the installation is convenient; and the power supply system and the control module are arranged in the packaged box, so that the light transmittance of the dimming film body can be controlled in multiple ways.

Description

technical field [0001] The invention relates to the field of dimming films, in particular to an easy-to-install dimming film with its own power supply. Background technique [0002] Dimming film is an electronic light control product, which means that polymer dispersed liquid crystal is solidified between two transparent conductive films. In the absence of an electric field, the dimming film is in an opaque state. When AC is applied, is transparent. [0003] The principle of action is that polymer-dispersed liquid crystals are mixed with low-molecular liquid crystals and prepolymers, and polymerized under certain conditions (through UV curing or thermal curing polymerization) to form micron-sized liquid crystal droplets that are evenly dispersed in polymers. In the network, the dielectric anisotropy of liquid crystal molecules is used to obtain materials with electro-optic response characteristics. It mainly works between the scattering state and the transparent state and h...

Problems solved by technology

For example, in a customized product, the dimming film is sandwiched between two glass panels, the edges are either directly exposed, or the process is used to seal the assembly. In any case, it is impossible to completely seal the dimming film to the glass interlayer Among them, the packaging of the dimming film has the problem of poor sealing, which makes the dimming film very susceptible to moisture and loses its efficacy during use; The film is sealed on the glass panel, so that the dimming film will be well sealed between the silica gel layer and the glass panel, but this method will inevitably wrap the gas in the silica gel layer, which will seriously affect the appearance and light transmission of glass products Effect
