PDLC technology controls the alignment of liquid crystal molecules via voltage, achieving instantaneous switching between transparent and frosted states. It boasts fast response and low power consumption, making it the most widely used technology on the market. EC technology, on the other hand, alters the light transmittance of materials through ion implantation and migration, enabling continuous, stepless adjustment between transparent and dark states. It offers advantages in active heat insulation and anti-glare. Generally, PDLC focuses on privacy protection and the immediacy of light and shadow switching, while EC excels in building energy conservation and intelligent temperature control.

Globally, smart glass is growing at an unprecedented rate. Industry research data shows that the global smart glass and smart window market size was approximately US$7.96 billion in 2025 and is projected to jump to US$9.23 billion by 2026, representing a CAGR of 16.0%. Another report indicates that the global smart glass market is valued at US$8.3 billion in 2026 and is expected to grow to US$24.1 billion by 2034, with a CAGR of approximately 14.2%. In specific segments, the electrochromic smart glass market is also showing strong performance, projected to grow from $3.98 billion in 2025 to $4.44 billion in 2026, representing a CAGR of 11.5%.

The Ningbo Institute of Materials Technology and Engineering achieved significant breakthroughs in the long lifespan and fast response control of inorganic electrochromic devices, successfully expanding to large-area smart windows of 10×10 cm², providing a solution with engineering potential for energy-efficient buildings and vehicle dimming systems. Meanwhile, the intelligent window product developed by Academician Yu Shuhong's team maintains a high light transmittance of 86.8% in low-irradiance environments and can achieve self-driven electrochromic properties by absorbing ultraviolet light under strong solar irradiance conditions, effectively blocking solar radiation.

From high-end optional features to large-scale implementation, smart glass is accelerating its entry into the mainstream consumer market.

In the past, smart glass was mainly used in a few luxury models and high-end commercial buildings. However, 2026 saw a major turning point in the industry—smart glass began to enter a concentrated implementation phase across multiple models, price points, and scenarios. At the 2026 Beijing International Automotive Exhibition, several new mass-produced models were equipped with mature electrochromic intelligent dimming systems, extending their application scenarios from panoramic sunroofs to core areas such as side windows and rear cabins, forming an integrated vehicle lighting environment control layout. The role of smart glass is shifting from a single configuration item to a more complete cabin "light environment" solution.

From a price perspective, the product price range has steadily decreased to the mainstream consumer range of 250,000 to 400,000 yuan, and the models equipped with it have expanded from a few high-end brands to more joint venture and domestic brands. Globally, over 300,000 mass-produced vehicles equipped with electrochromic technology have been delivered, with applications covering key components such as panoramic sunroofs and windows. This signifies that smart dimming glass has officially entered a new stage of industrialization focused on engineering stability, mass production consistency, and full-cycle quality control. In the field of architectural design, the application of dimming glass is also experiencing a growth inflection point. The Third Children's Hospital has adopted "smart glass" equipped with a temperature-sensitive nanogel layer, which automatically adjusts its transparency and fogging states according to ambient temperature without an external power source, achieving a heat radiation blocking rate of over 90% and enabling adaptive adjustment of the indoor light and heat environment.

With patent strategy in place, XtalPi has built a strong competitive advantage in smart dimming technology.

In the field of smart dimming glass, Zhejiang XtalPi Technology has already taken proactive measures. In September 2023, the company submitted a utility model patent application to the State Intellectual Property Office for "A Smart Dimming Bulletproof Glass Structure," which was granted in May 2024. This patented technology innovatively integrates intelligent dimming functionality with bulletproof safety features, employing a multi-layered composite structure design—consisting of a first glass layer, a PVB interlayer, an intelligent dimming layer, a second PVB layer, and a second glass layer—while simultaneously achieving three core performance indicators: dimming response speed, bulletproof performance, and optical quality. This technology allows the glass to meet the dimming requirements of transparency when powered on/fogging when powered off, while still maintaining excellent impact resistance and penetration resistance, expanding the application boundaries of intelligent dimming glass in security-sensitive scenarios such as financial security and special vehicles.

According to public reports, as of 2020, Jingtai Glass had invested over ten million yuan in scientific and technological research and development and technological upgrades, possessing 34 authorized patents. In 2020, the company owned 47 independent intellectual property rights and passed the GB/T29490 intellectual property management system certification. In recent years, the company's intellectual property accumulation has continued to grow. In the field of smart glass, the company has also jointly applied for an invention patent with Quzhou University for "A method for preparing Nb and Ce co-doped WO3 photonic crystal special electrochromic glass," actively developing electrochromic technology and exploring the preparation process of next-generation high-performance electrochromic smart glass. This continuous R&D investment and intellectual property accumulation have built a solid technological moat for the company in the competitive smart dimming glass market.

Core Technology Roadmap: PDLC and EC in Parallel Development

Currently, intelligent dimming glass is mainly based on two core technology roadmaps. PDLC technology controls the alignment of liquid crystal molecules through voltage, achieving instant switching between transparent and frosted states. The response speed is as fast as milliseconds, and it frosts immediately upon power failure, with extremely low continuous power consumption. This mature and cost-effective technology is currently the mainstream solution in the building decoration field, widely used in hotel partitions, shower rooms, office partitions, and commercial shop windows.

Electrochromic technology, on the other hand, is a more advanced solution. By altering the light transmittance of materials through ion implantation and migration, it can be infinitely adjusted between transparent and dark colors, achieving intelligent management throughout the entire process from light regulation and thermal insulation to privacy protection. Compared to PDLC, the biggest advantage of EC technology is its ability to continuously adjust light transmittance, achieving active thermal insulation and anti-glare, significantly reducing building cooling energy consumption. Electrochromic smart windows can dynamically adjust the transmittance of visible and near-infrared wavelengths under low applied voltage, synergistically achieving solar radiation management and visual comfort, making it one of the key technologies supporting "dual-carbon" goals and zero-carbon buildings.

It is worth mentioning that photochromic and thermochromic glass, as passive dimming technologies that do not require power, are also demonstrating their application value in specific climate scenarios and green building applications. Globally, different types of smart glass technologies are developing in parallel, providing a wide range of choices for different application scenarios.
