How does the smart glass work?

AJJ Smart Glass Sample

Smart glass changes between clear and opaque by the electric voltage control.

The liquid crystal within the dimming film of the smart glass is out of order under the nature state (power off), it is in a mess. In this case, the refractive index of liquid crystal is lower than the one of polymer outside (high molecular material). The scattering happens when the incident light arrives at the polymer. You will find the whole set of the glass is opaque, like sandblasted glass.

When power on, two pieces of the PET film like two planar electrodes, making the polymer drop align again, and the liquid crystal changes to be ordered arrangement, and finally the refractive index between liquid crystal and polymer is the same, light can get through the glass . the smart glass presents an transparent appearance.

What is switchable privacy glass

AJJ swtichable glass is also called privacy glass, lcd glass, smart glass, electrical glass,etc. Privacy at the flick of a switch is possible with Switchable glass. This is state of the art laminated glass with a liquid crystal interlayer between two sheets of glass, either clear or tinted. The liquid crystal film and the glass panels are assembled by means of two interlayer films ( exp EVA film).

In clear mode an electrical current is passed through the interlayer which aligns the microscopic crystals along a number of parallel axes, thus allowing vision through the glass.

When privacy is required the current is switched off and the crystals scatter into a random formation which prevents vision through the glass.

Technical parameters:
The light transmittance of switchable glass is not less than 75%, and its anti-light transmittance is not more than 10%.
The switching speed of switchable glass is less than 0.1 sec.
The visual angle of switchable glass is not less than 140°.
The current of switchable glass is not more than 8 w/m2.
Siwtchable glass should endure 120V alternating current, and breakdown does not take place during 60 hours.
The working life of switchable glass is not less than 50000 hours.
Privacy glass can work normally in -10℃ ~ +60℃ circumstance.
The working voltage of privacy glass is 75V-100V alternating current, frequency is 50 Hz, it should work normally in the circumstance of voltage fluctuation is not more than 10V.

Standards and dimensions:
Avaliable maximum sizes: 1200mm x 3000mm (applicable for multichip connection)
Thickness: 7mm (3+1+3), 9mm(4+1+4), 11m(5+1+5), 13mm(6+1+6), 17mm(8+1+8)

Applications:
Typical appications include control room and command center for govement facilities, executive offices and conferences room, special effects for entertainment industry, exhibition, and outdoor advertisement.

Principle and structure of smart glass

Principle and structure of product　

As shown in figures, the principle of product is as follows:　


(1)When smart glass is turned off, the high molecular liquid crystal material in glass presents disorder arrangement, light can not pass through the glass, the glass appears cream white nontransparent state.　　

(2)When smart glass is turned on, due to the effect of the electric field, the high molecular liquid crystal material in glass presents ordered arrangement, light can pass through the glass, the glass appears transparent state.
