What is it?

Introducing the Liquid Crystal Voltage-Controlled Transparency Panel – Unlock Innovation through Your Window! At the core of this panel resides a Liquid Crystal Light Valve (LCLV), putting you in command of your glass panel's opacity by simply applying voltage across its terminals. A Liquid Crystal Light Valve (LCLV) is a device harnessing liquid crystal properties to regulate light levels within an optical system.

The panel is 9.7cm x 5.3cm and boasts a robust design featuring a PCB backing to ensure durability and stability. For a visual demonstration, please refer to the video below. In this demo, we've connected the panel to an Arduino Micro Pro, which in turn is linked to a rotary encoder. This setup allows for precise PWM adjustment, thereby altering the voltage across the panel and seamlessly changing its opacity levels.

The setup couldn't be simpler with just two pins:

• GND:
• EN: (Apply a single 3.3V to achieve complete blackout or utilize a PWM signal for precise opacity control.)

Potential Use Cases

• Eye Protection Helmet: Use it to protect your eyes from welding sparks and adjust the opacity to your liking.

• Personalized Escape Room: Create a DIY escape room experience by installing these panels in treasure boxes. Adjust the opacity to reveal clues and challenges as participants progress through the room. Or design mystery box challenges or puzzle boxes where participants must manipulate the panel's opacity to unlock hidden compartments and solve riddles.

• Retail Storefront Displays: Create captivating storefront displays that transition from opaque to transparent to showcase new products or promotions, piquing the curiosity of passersby.

• Interactive Learning Aids: Develop educational tools for children that use the panels to reveal hidden images or text as part of interactive lessons or storytelling.

• Virtual Reality (VR) Experiences: Integrate the panels into VR headsets to simulate different lighting conditions and adjust opacity for more immersive virtual environments.

• Cosplay Costume Transformation: Incorporate a Liquid Crystal Light Valve into a cosplay costume for an incredible transformation effect. With the panel seamlessly embedded in your outfit, control the opacity to reveal hidden designs, messages, or even mimic iconic character costume changes from your favorite series or movies. Embrace the power of LCLV for a cosplay experience like no other!
