This small LCD shutter panel acts as a single-pixel LCD display that switches between transparent and opaque states. Apply 3V to polarise the panel and it goes completely black; pull the voltage low or short the terminals and it becomes transparent again. Extremely low current draw makes it easy to drive from a microcontroller.
The shutter behaves like a low-value capacitor — once energised, it holds its opaque state but slowly leaks charge and becomes transparent over time. Best viewed from directly in front, as off-angle viewing may reduce opacity slightly. The panel is made of glass with sharp corners, so handle with care.

Jargon buster
Plain-language definitions for the technical terms used above.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
