SPD Smart Film – Smart Glass for Dynamic Light Control
Ultra-thin • Instant Privacy • Energy Efficient • Easy Installation
What is SPD Smart Film?
SPD (Suspended Particle Device) Smart Film is an advanced switchable smart glass technology that allows precise control of light transmission through an electrical current. It changes from a dark tinted state to a clear transparent state by aligning microscopic suspended particles inside the film. When the power is OFF, the particles scatter randomly, blocking light and providing privacy and solar shading. When the power is ON, the particles align uniformly, allowing light to pass through and restoring clear visibility.
SPD Smart Film
Suspended Particle Device (SPD) electrochromic technology. Instantly shifts from a dark blue, light-absorbing state to completely transparent, offering ultimate glare control, solar shading, and thermal comfort.
Deep Dark State
When powered off, SPD particles absorb over 98% of visible light, creating a deep blue opaque state for excellent solar shading.
Precise Tint Control
The entire tinting and bleaching process can be precisely controlled by adjusting the 90V AC voltage.
99% UV Blocking
Provides outstanding sun protection by blocking up to 99% of harmful UV rays across all tint states.
Ultra Low Power
Consumes only ~3 W/m², making it a highly energy-efficient solution for large-scale glazing projects.
Technical Parameters
How SPD Technology Works
SPD works by dispersing millions of suspended particles between two transparent conductive layers. The tint level dynamically responds to applied voltage:
- Power OFF = Dark Blue (Opaque)The SPD particles remain randomly distributed, absorbing over 98% of visible light. The film appears in a deep dark blue state, heavily reducing solar glare and heat.
- Power ON = Transparent (Clear)When 90V AC current passes through the conductive layers, the particles instantly align in an orderly manner. This allows light to pass through, switching the film to a highly transparent state (60% transmittance).
