|
| Gentex uses its proprietary, solution-phase electrochromic technology. We sandwich an electrochromic gel between two pieces of glass, each of which has been treated with a transparent, electrically conductive coating, and one with a reflector.
|
|
|
| 1. |
|
A forward-facing sensor recognizes low ambient light levels and signals the mirror to begin looking for glare.
|
 |
| 2. |
|
A rearward-facing sensor then detects glare from the vehicles traveling behind you, sending voltage to the mirror's EC gel in proportion to the amount of glare detected.
|
|
| 3. |
|
The mirror dims in proportion to the glare and then clears when the glare is no longer detected.
|
|
| 4. |
|
The interior mirror's sensors and electronics control the dimming of both interior and exterior mirrors.
