In this product, we have one huge LCD piece, which will filter what you see through it.
Normally, its a tinted gray color (because the light around us is not polarized, it is not
completely clear). There are two sets of electrodes, on the left and right. The two pins
closest to each other (on the edges) are the same electrode, and the LCD is symmetric so
you can use either one as positive/negative.
By changing the voltage applied, it will block light more and more. Starting at about
1.0VDC the glass will start darkening. At about 4.0V the glass will be opaque. 5V is the
max recommended voltage. In between you will get darker shades. Note that it is not
capable of blocking 100% of light, but it looks like it blocks at least 95%. If you put a
bright light behind it, you will see some light shine through!
Almost no current is used and one the LCD, once activated with a voltage, will stay at
that darkness level even if the voltage is removed. So, if you want to have it turn on and
off, you'll need to drive it with a 0V signal to 'open' it up, or connect a draining resistor
between the two pins to leak the voltage off when not powered.
Please note that this is a thin piece of glass, you can't bend it and its very delicate! Use
care when working with this item.
