Liquid Crystal - LCD Controllable Black-out Panel
A Liquid Crystal Light Valve (LCLV) is a device that uses the properties of liquid crystals to control the level of illumination passing through an optical system. It's basically what goes on in your LCD monitor/TV/projector etc, but for each individual pixels.
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.
