OnFace SDC which has been steadily growing with excellent technology and quality.


Smart Window ‘ECM’

It is an auto-discoloration mirror developed by OnFace SDC technology
that automatically detects the light from the rear vehicle entering
the room mirror through the optical sensor to lower the reflectance
of the mirror to eliminate the driver’s glare.

ECM room mirror for clean view of driver

Electrochromic Technology

Electrochromic material

A material having properties such that ions such as H + or Li + are injected (reduced) or separated (oxidized)
by the application of an electric field to change color and transmittance.
WO3 (Tungsten Oxide) NiO (Nickel Oxide) IrO2 (Iridium Oxide) V2O5 (Vanadium Oxide) etc.

WO, thin film deposition process technology of electrochromic materials
Thin film deposition process technology of NiO electrochromic materials (DC sputtering technology)
