South Korea Smart Glass and Smart Window Market Size and Share - Outlook Report, Forecast Trends and Growth Analysis (2025-2034)

The South Korea smart glass and smart window market is expected to grow at a CAGR of 14.50% between 2025 and 2034. The growing government support along with increased usage in the residential as well as commercial sectors are majorly driving the smart glass and smart window markets in South Korea.

Key Trends in the Market

Smart glass, often known as switchable glass, is a type of glass that combines modern technology to both restrict light and insulate it. Heat, electricity, and light all have an impact on the glass's ability to transmit light. Generally, this implies that the glass transitions from translucent to transparent, blocking some, all, or specific wavelengths of light. In homes, companies, and establishments like hospitals, this technology may be used to regulate light and heat, and also help in maintaining privacy. In comparison to manual solutions like blinds, curtains, shades, and doors, they provide cleaner surroundings and better and more varied degrees of control.

The Collaboration Between Two South Korean Conglomerates LG and Kakao to Install OLED Smart Glass Window to Drive the Market

In 2021, LG Display  provided a 55-inch OLED display for digital signage for parking lot infotainment systems, including utilisation data for "Kakao T Parking" and customer-participatory marketing. As Kakao Mobility develops COEX as a platform for smart mobility in big cities, this supply will offer a distinctive parking service experience with futuristic displays. The parking facility of COEX has approximately 40 million people visiting each year and is also the largest of any domestic architecture. Storefront windows, billboards, and train cars all use this OLED. The business is aiming for growth in a number of areas in the future, including driverless vehicles, aviation, and home interiors.

Market Opportunities and Challenges

Exhibitions Provide a Global Platform for the Companies to Showcase their Innovations

In keeping with the "Display Your Universe " theme, LG Display unveiled a number of displays and high-end technologies at CES 2023, the largest international IT and home appliance expo in the world. In this event, LG Display unveiled "OLED.EX," which advances visual quality with advanced and tailored algorithms, a "transparent flexible OLED solution," which conjures up a vision of the home of the future, "IPS Black," a high-end display technology for IT, as well as gaming OLED and a 17-inch folding OLED for laptops.

The Use of Smart Glass and Window Technology in Various Industries to Augment the Market Growth in South Korea

LG Display is in the process of developing transparent OLED for subway windows, allowing passengers to read daily information including schedules, location data, weather forecasts, and headlines while also viewing the outside landscape through the subway glass window. Various information and advertisements appropriate for the time and location can be displayed directly on the glass window, like augmented reality when passing well-known landmarks and tourist attractions. The market for these modern and revolutionary products is anticipated to expand and be applied to several fields, including the mobility field in South Korea.

Increased Usage in Electric Vehicles and Government Support via Start-ups Assistance Programs

Smart Glass, which has the ability to top-up EV batteries by 10-15 miles per day and block heat from entering cars and buildings, continues to attract customers as EVs and hybrid automobiles make up a larger share of worldwide vehicle sales. The South Korean government proactively promotes technical research and development in the country. One example of government assistance for start-ups is through TIPS  (Tech Incubator Program for Firms), a state-led incubation programme that uncovers and fosters potential entrepreneurs by strategically combining them with government financing. To maintain and strengthen the momentum, South Korea formed the Ministry of SMEs and start-ups in 2017 to systematically manage numerous start-up assistance programmes. Korea's economic strategy now includes the expansion of science and technology as a crucial component.

High Initial Cost 

The high initial cost of installation and material costs pose a challenge. However, growing consumer awareness regarding the market and an inclination to stay updated with the latest technology could help in market expansion. The market is also being driven by rising environmental concerns and people's preference for high-tech, environmentally friendly products.

Market Segmentation

South Korea Smart Glass and Smart Window Market Report and Forecast 2025-2034 offers a detailed analysis of the market based on the following segments:

Breakup by Technology

• Active
• Passive

Breakup by End Use

• Automotive
• Aviation
• Marine
• Construction
• Others

Market Share by Technology

Polymer Dispersed Liquid Crystal (PDLC), Suspended Particle Device (SPD) glass, and Electrochromic (EC) are three variants of active smart glass which are used in the commercial as well as residential sectors. Photochromic and thermochromic smart glasses are the passive smart glass types that are used in sunglasses and temperature-sensitive windows. However, the market for active smart glasses is gaining traction due to people's inclination toward advanced technology. Active smart glass offers better functions and changes its appearance upon its activation. These are particularly used in the automobile industry and smart homes, among others.

Market Share by End-Use

The expansion of the smart glass market is anticipated to be fuelled by the growing consumer preference for better aesthetics in both commercial and residential settings. For aesthetics and increased thermal and visual comfort for people, as well as significant energy savings, smart windows are used in conjunction with lighting and air conditioning systems. Smart technology is being used by architects in new construction at an exponential rate, which is predicted to boost the market for smart glass and smart windows for architectural purposes.

The increased use of electric and hybrid vehicles in South Korea is compelling the manufacturers to employ the latest technologies in their vehicles while also promoting sustainability. Other segments are also expected to grow due to the increasing monetary support from the government for technologically oriented start-ups and research and development is further propelling the South Korea smart glass and smart window market.
