{"title":"Small Liquid Crystal Light Valve - Controllable Shutter Glass","handle":"small-liquid-crystal-light-valve-controllable-shutter-glass","url":"/products/small-liquid-crystal-light-valve-controllable-shutter-glass","description":"A Liquid Crystal Light Valve (LCLV) is a small piece of liquid crystal material sandwiched between two glass sheets that can be electronically switched from semi-transparent to opaque. By varying the applied voltage, you can control how much light passes through — perfect for \"reveal\" effects, variable-opacity displays, and electronic shutter applications.\n\nAt rest (no voltage), the glass appears tinted grey since ambient light is unpolarised. Applying voltage from around 1.0 V begins darkening the panel, with full opacity reached at approximately 4.0 V (blocking ~95% of light). Maximum recommended voltage is 5.0 V.\n\nKey Features\n\n\nVariable Opacity – Adjust voltage between 1.0–4.0 V to control light transmission\n\nNear-Zero Current Draw – Capacitive behaviour means the panel holds its state even after voltage is removed\n\nReset via 0 V – Apply 0 V or connect a drain resistor to return to the transparent state\n\nMaximum Voltage – 5.0 V DC\n\nLight Blocking – Approximately 95% at full opacity\n\n\nIdeal For\n\nElectronic shutter and reveal effects\nVariable-opacity windows and displays\nArt installations and interactive projects\n\n\n\nWarning: This is a thin glass panel — it cannot be bent or cut and is very fragile. Handle with care.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8545,"title":"Default Title","sku":"AF-3627","price":6.3,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
