Generally there are 2 factors that will affect the switchable smart film transparency visual difference.
One is installation site environment, if the installation site is very bright, then visual transparency is high.
The other factor is electrode/busbar (bb) position.
If bb on the one short side only, the best width and length ratio is within 1:3.
Otherwise, bb on the long side or 2 short sides.
But when we choose bb position, we also need to consider 2 factors.
One is how to cover and hide the wires perfectly.
The other one is wiring convenience.
So finally you have to compromise on the bb position and transparency according to different factors and installation site.
For us, we never compromise on quality and we always supply you the same high quality and high transparency smart film for sure.
