SMART GLASS PDLC SPD Electrochromic Controller Area Network

SUSPENDED PARTICLE DEVICES

SPD glass is used for solar gain control to reduce heating effects and to reduce photo-chemical deterioration of light sensitive objects.

In SPD-based smart glass, a thin film laminate of rod-like particles suspended in a fluid is placed between two glass or plastic layers or attached to one layer.

When no voltage is applied, the suspended particles are arranged in random and tend to absorb light, and the glass panel looks opaque, providing maximum protection to light-sensitive objects.

When voltage is applied, the suspended particles align and transmit light.

SPD-based smart glass can also be dimmed, and allows instant control of the amount of light and heat passing through it.

A small electrical current is required to keep the SPD smart glass in its transparent stage. In its opaque state it consumes no power at all.
