In South Korea, a global leader in advanced technology and eco-innovation, smart glass is increasingly being used to align with sustainability goals, smart city development, and high tech design trends. Its core functionality allows control over solar heat and visibility, making it highly relevant in modern architecture and connected environments. South Korea’s fast-growing demand for energy-efficient solutions is driving the adoption of smart glass across industries. Particularly in architecture, it is featured in building facades, skylights, atriums, and interior partitions in major cities like Seoul and Busan, contributing to daylight optimization and solar control. Government incentives such as energy efficiency credits and regulations like the Zero Energy Building program have fueled its integration in commercial and institutional buildings. In smart homes and offices, smart glass is used in windows, room dividers, and bathroom enclosures enabling privacy on demand, reduced glare, and a sleek, minimalist aesthetic.

Hyundai and Kia have introduced electrochromic sunroofs and SPD glass panels in their luxury and EV models, providing thermal regulation and enhancing driving comfort. Korea Railroad Corporation (KORAIL) has piloted smart glass in train cabins for glare-free viewing and privacy, improving passenger experiences. Challenges such as high production and installation costs, and limited consumer awareness in residential segments, are still barriers. There are also lifecycle concerns related to long-term durability, especially in regions experiencing extreme seasonal changes. That said, innovation in low-cost manufacturing and durable smart coatings is underway. Integration with AI, IoT, and automated building management systems is accelerating, allowing glass to respond dynamically to user behavior and climate data.According to the research report, “South Korea Smart glasses Market Research Report, 2030," published by Actual Market Research, the South Korea Smart glasses market is anticipated to add to more than USD 140 Million by 2025–30. By controlling solar heat gain and reducing the load on HVAC systems, it contributes to lower carbon emissions and enhanced building performance.

Lotte World Tower in Seoul incorporates smart façade solutions to meet both aesthetic and sustainability goals. Recycling and material reusability are emerging focus areas, with Korean manufacturers working on environmentally friendly smart coatings and more recyclable substrates. With the rise of smart city initiatives, smart glass is also being embedded in interactive kiosks, digital signage, and smart bus stops across Seoul, using voice and motion sensors to dynamically adapt content or lighting based on the surroundings. Consumer electronics is another innovation frontier. LG’s transparent OLED smart windows and Samsung’s concept displays use smart glass for touch-sensitive, energy-efficient, and visually transparent screens. In smart refrigerators, users can knock twice to illuminate the interior through a PDLC panel, reducing the need to open the door saving energy while enhancing convenience.

North America and Europe continue to lead in early smart glass adoption, but South Korea, as part of the APAC region, is rapidly advancing due to urbanization, strong R&D ecosystems, and government-backed digital transformation policies. Urban centers are seeing increasing smart glass use in hospitals, data centers, high-rise apartments, and even schools, improving energy efficiency and occupant well-being. South Korea's smart glass market will grow at a CAGR of over 11% in the next five years, driven by its use in commercial real estate, premium automotive models, next-gen electronics, and sustainable public spaces. Electrochromic technology is one of the most widely adopted in South Korea. It changes light transmission properties in response to voltage, allowing for real-time control of glare and solar heat gain. This technology is particularly suitable for commercial buildings and luxury residential projects, where energy efficiency and comfort are paramount.

Polymer Dispersed Liquid Crystal (PDLC) technology is gaining popularity in South Korea for its ability to switch between transparent and opaque states. This feature is ideal for applications requiring instant privacy, such as conference rooms, healthcare facilities, and high-end residences. The rapid response time and ease of integration make PDLC a preferred choice for interior applications. Suspended Particle Devices offer precise control over light and heat transmission by aligning nano-scale particles in response to an electric field. This technology is emerging as a lucrative segment in South Korea, especially in automotive applications, where adjustable shading and glare control are essential for passenger comfort. The automotive industry, home to global giants such as Hyundai and Kia, has increasingly incorporated smart glass in their latest models, adding to the demand curve.

Thermochromic smart glass changes its properties in response to temperature variations. While still in the early stages of adoption in South Korea, this passive technology holds promise for passive solar control in residential buildings, reducing the need for active heating or cooling systems. Photochromic smart glass, which darkens in response to sunlight exposure, is primarily used in eyewear but is being explored for façade applications in buildings. In the architectural sector, smart glass is increasingly used in commercial buildings, luxury residences, and public infrastructure. Its ability to regulate light and heat entering a space contributes to energy savings and improved occupant comfort. Features such as automatic glare reduction and privacy control are particularly valued in urban environments.

The transportation sector in South Korea is also adopting smart glass technologies. In the automotive industry, smart glass is used in sunroofs, windows, and rear-view mirrors to provide adjustable shading and reduce glare. This enhances passenger comfort and contributes to energy efficiency by reducing the need for air conditioning. Smart glass is being explored for use in public transportation systems, such as trains and buses, to improve passenger experience. In consumer electronics, smart glass is being integrated into devices such as smartphones, tablets, and wearables. The technology enables features like privacy screens, glare reduction, and interactive displays, enhancing user experience and device functionality.

As consumer demand for innovative and functional electronics grows, the adoption of smart glass in this sector is expected to increase. The power generation sector in South Korea is exploring the use of smart glass in photovoltaic applications. Smart glass integrated with solar cells can generate electricity while regulating light and heat transmission, contributing to energy efficiency in buildings and infrastructure. This dual-functionality aligns with South Korea's renewable energy goals and sustainable development initiatives.Considered in this report• Historic Year: 2019• Base year: 2024• Estimated year: 2025• Forecast year: 2030Aspects covered in this report• Smart Glasses Market with its value and forecast along with its segments• Various drivers and challenges• On-going trends and developments• Top profiled companies• Strategic recommendationBy Technology• Electrochromic• Polymer Dispersed Liquid Crystal (PDLC)• Suspended Particle Devices (SPD)• Thermochromics• PhotochromicBy Application• Architectural• Transportation• Consumer Electronics• Power GenerationThe approach of the report:This report consists of a combined approach of primary as well as secondary research.
