Industry Developments and Trends
1. Technological Evolution: From Basic Dimming to Multifunctional Integration
By 2026, PDLC (Polymer Dispersed Liquid Crystal) dimming film technology is evolving from simple binary switching—between transparent and opaque states—to three-dimensional light control. While traditional PDLC was limited to toggling between two states, next-generation products offer stepless light transmission adjustment, complete blackout capabilities, and enhanced visual aesthetics. Furthermore, they integrate with smart home electronic systems and provide full-spectrum thermal insulation—blocking 99.99% of UV rays and 90% of infrared radiation (equivalent to SPF 130+ sun protection)—making them a standard feature in premium architectural design.
Key Application Scenarios:
Construction Sector: Glass partitions for office buildings, privacy solutions for hotels, flexible space division for villas and guesthouses, and heat insulation/energy saving for sunrooms (reducing energy consumption by over 30%).
Commercial Settings: Spatial expansion for conference rooms, switchable projection screens, temporary partitions for exhibition halls, and sterile observation windows in medical facilities that safeguard patient privacy.
Industry Standards and Selection Guide
Core Technical Specifications
Optical Performance: Visible light transmittance (transparent state) ≥75%; haze (opaque state) ≤5%; UV rejection rate ≥99%; haze switching time ≤0.1 seconds
Durability and Safety: Aging resistance ≥3,000 hours; explosion-proof rating compliant with ASTM E2190; operating temperature range -20°C to 80°C
Smart Control: Supports 0-10V dimming and Zigbee/BLE wireless protocols; power consumption ≤5W/m²; operating voltage ≤48V DC
In addition to the PDLC technology route, technologies such as EC (electrochromic) and SPD (suspended particle device) also hold a share of the smart dimming glass market, offering a wider range of technological options:
EC Technology: Representative companies include Shenzhen JiSu Smart Tech; products maintain their state after power is cut off, feature extremely low haze and exceptional clarity, and offer a high dimming ratio, though costs are higher and response speeds are slower.
SPD Technology: Representative companies include Shenzhen JiSu Smart Tech; features include rapid dimming, high color saturation, and the ability to switch between multiple colors, though costs are higher and operation requires a high-voltage (110V or 220V ) drive.
Respective advantages: PDLC (Polymer Dispersed Liquid Crystal) technology dominates the low-to-mid-end market due to its cost advantages and rapid response capabilities; EC technology holds an advantage in the high-end market; and SPD (suspended particle device)technology is competitive in specific application scenarios.
