How Smart Dimmable Glass Achieves the Free Switching Between Privacy and Daylight
Smart Dimmable Glass, also known as electrochromic glass or switchable glass, is a high-tech glass that can switch between transparent and opaque (frosted) states. It is widely used in office partitions, bathrooms, conference rooms, car windows, medical privacy screens, and other scenarios, achieving free adjustment of privacy and daylight through intelligent control.
1. Core Technical Principles of Dimmable Glass
Dimmable glass mainly relies on the following two technologies to achieve the switching between transparent/frosted states:
① Liquid Crystal Dimmable Glass (PDLC - Polymer Dispersed Liquid Crystal)
- Structure: Composed of two layers of glass sandwiching a PDLC liquid crystal film, with conductive polymer liquid crystal material filled in the middle.
- Working Principle:
- When powered on (transparent state): The electric field makes the liquid crystal molecules arrange neatly, allowing light to pass through, and the glass is in a transparent state.
- When powered off (frosted state): The liquid crystal molecules are arranged disorderly, and the light is scattered, making the glass appear milky white and frosted, blocking the line of sight but still allowing light to pass through.
- Features: Fast response speed, low energy consumption, adjustable transparency, suitable for indoor partitions, building exterior walls, etc.
② Electrochromic Glass
- Structure: Composed of multiple layers of materials such as glass, transparent conductive layer, electrochromic layer, and ion transport layer.
- Working Principle:
- By applying a low voltage, the electrochromic material (such as tungsten oxide) undergoes an oxidation-reduction reaction, changing the color and light transmittance of the glass.
- The transparency can be gradually adjusted, from completely transparent to dark light-shielding, not only adjusting privacy but also used for sun shading and energy saving.
- Features: Continuously adjustable light transmittance, suitable for smart buildings, solar shading systems, etc.
2. Application Scenarios of Dimmable Glass
- Building glass curtain walls: Provide adjustable lighting effects, reduce direct sunlight, and improve energy efficiency.
- Office partitions: Achieve switching between transparency and privacy, improving space utilization.
- Bathroom glass: Replace traditional frosted glass, enhancing privacy protection and modernity.
- Medical institutions: Used in wards, operating rooms, etc., providing an immediate privacy solution.
- Smart car glass: Can be used for car windows and sunroofs, reducing glare and improving comfort.
3. Advantages of Dimmable Glass
Privacy protection: One-button switching between transparent/frosted, no need for curtains or blinds.
Intelligent control: Can be linked with Mobile, remote control, and sensing systems to achieve intelligent operation.
Energy saving and cooling: Electrochromic glass can reduce ultraviolet rays and heat from entering the room, reducing air conditioning energy consumption.
Safety protection: Can be combined with laminated glass to improve impact resistance.
