Dimming laminated glass (STG), also known as electronically controlled liquid crystal dimming laminated glass, photoelectric glass, PDLC glass, smart glass, electronic curtains, electro-optical glass, electro-liquid crystal atomized glass, etc., is a combination of liquid crystal film into two layers of glass. In the middle, a new type of special optoelectronic glass product formed by high temperature and high pressure lamination, in which the liquid crystal film is opaque in a fog state when the power is off, and transparent when it is powered on, so that the dimming glass has the characteristics of ordinary glass and electronically controlled curtains.

Switchable Glass (Switchable Glass) is to cure the switchable film STF (full name is polymer dispersed liquid crystal film PDLC-Polymer Dispersed Liquid Crystal film is a combination of liquid crystal-plastic layer in two flexible ITO transparent conductive films) in two pieces. Between the glass, in the natural state, the liquid crystal polymer inside the liquid crystal film is irregular, and the incident light is scattered in the polymer, which is milky white, that is, opaque. After electrification, the liquid crystal polymers with dispersed distribution are rearranged from disordered arrangement to directional ordered arrangement, and the incident light can completely pass through, forming a transparent state.

Features

The characteristics of power-on transparency and power-off frosting of the electronically controlled dimming glass originate from the "electro-optical effect" of the dimming film. After it is made into a laminated product, it also has the following characteristics:

1. Safety: The production process of laminated glass is adopted. The film in the interlayer can firmly bond the glass, so that when the dimming glass is impacted and broken, the glass fragments are bonded in the film, and the glass fragments will not splash and hurt people.

2. Environmental protection features: 2. Film and my dimming film in the dimming glass can shield more than 90% of infrared rays and more than 98% of ultraviolet rays. Shielding infrared rays can reduce heat radiation and transmission, and shielding ultraviolet rays can protect indoor furnishings. Fading and aging due to ultraviolet radiation.

3. Sound insulation characteristics: The optical glass interlayer has a sound damping effect, which can effectively block all kinds of noise.

4. Privacy protection function: 4. The biggest function of the smart dimming glass is the privacy protection function, which can control the transparent and opaque state of the glass at any time.

5. Projection function: 5. The smart dimming glass is also a very good projection hard screen. In a suitable light environment, the projection effect is very outstanding.
