Analysis of Indoor Transparent LED Screens
I. Technical Principles and Core Advantages
High Transparency Design
Through a hollow strip structure, fine-pitch LED arrangement, and transparent conductive technology, a light transmittance of 65%-90% is achieved. For example, the Maipu Guangcai P3.91 model boasts industry-leading light transmittance. After installation, it does not affect indoor lighting. When not in use, the screen becomes virtually invisible, seamlessly blending in with glass curtain walls, display windows, and other settings.
Lightweight and Thin Structure
The mainboard thickness is only approximately 1 cm, and the weight is as low as 5-15 kg/㎡ (such as Zhongrun Optoelectronics products). This significantly reduces the load requirements on the building structure and supports various installation methods, including wall-mounted, suspended, and embedded, adapting to complex space requirements.
Energy Saving and Optimized Heat Dissipation
The natural heat dissipation design eliminates the need for air conditioning and reduces power consumption by over 30% compared to traditional LED screens. For example, the average power consumption of the Maipu Guangcai P3.91 is as low as 240 W/㎡, meeting green building standards. High Brightness and Color Performance
With a brightness of 1100 cd/m² (Maipu P3.91), a contrast ratio of 1:5000, and support for 16 million colors, this technology ensures clear content in bright sunlight and high color reproduction, making it ideal for commercial advertising and art displays.
II. Core Application Scenarios
Commercial Spaces
Window Displays: Display product advertisements or promotional information to attract customers (e.g., in retail stores and auto dealerships).
Atriums and Partitions: Install transparent screens in shopping mall atrias, sightseeing elevators, or glass partitions to display brand promotions or event information, enhancing the space's sense of technology.
Hotels and Restaurants: Install transparent screens on lobby and restaurant walls to display menus, special offers, or promotional videos, creating an immersive atmosphere.
Culture and Exhibitions: Museums and Science and Technology Museums: Display cultural relics, artwork, or scientific and technological achievements, combining the transparency of transparent screens to create a "virtual-real" viewing experience.
Stage Performances: Serving as a stage backdrop, performers can interact with the screen content, creating dreamy visual effects (such as the mesh screen used at the Hangzhou Asian Games closing ceremony). Enterprise and Public Spaces
Office Spaces: Install transparent screens in conference rooms and partitions for information display or video conferencing, maintaining an open feel.
Transportation Hubs: Install transparent screens on glass walls in places like airports and subway stations to display navigation information or public service announcements, balancing practicality and aesthetics.
III. Key Product Selection Parameters
Pixel Pitch (P)
P3.91: Suitable for medium- to close-range viewing (such as indoor commercial displays), with a resolution of 32,768 dots/㎡ and detailed images.
P7.82: Suitable for long-range viewing (such as building curtain walls), with lower cost and higher light transmittance.
Light Transmittance and Brightness
Light transmittance should be selected based on the application requirements: ≥70% is recommended for window displays, while 65%-80% is acceptable for building curtain walls.
Brightness should match the ambient light: 1000-1500 cd/㎡ is sufficient for indoor environments, while higher brightness is required in bright sunlight.
Easy Installation and Maintenance
The modular design allows for quick replacement of individual light strips, reducing maintenance costs. Lightweight construction (e.g., Zhongrun Optoelectronics products weigh only 12-15 kg/㎡) reduces installation difficulty and shortens construction time.
IV. Cost and Budget Reference
Screen Price
P3.91 model: approximately 3,000-6,000 RMB/㎡ (e.g., Maipu Guangcai products are quoted at 3,535 RMB/㎡).
P7.82 model: approximately 2,000-4,000 RMB/㎡, suitable for projects with limited budgets.
High-end customization: such as custom-shaped screens (cylindrical, spherical) or interactive screens, can cost double.
Additional Costs
Control System: approximately 500-1,500 RMB/set, supporting remote content updates.
Installation and Commissioning: approximately 100-300 RMB/㎡, including structural frame and wiring layout.
Transportation and Taxes: Fluctuate based on distance and regional policies.
V. Typical Cases and Supplier Recommendations
Zhongrun Optoelectronics
Case studies: Hangzhou Asian Games Closing Ceremony Floor Screen and Transparent Screen for the Sanya Ethnic Minority Games. Advantages: Provides integrated solutions from R&D, design, and maintenance, supporting customizable custom screens.

VI. Limitations and Development Trends
Current Limitations
The conflict between clarity and transparency: High transmittance requires a sacrifice in pixel density, resulting in a lack of image detail.
Light Interference: The transparency effect is diminished in strong light environments, requiring optimization with anti-reflective coatings.
Future Trends
Micro LED technology integration: Improves pixel density and brightness, achieving higher-definition transparent displays.
Intelligent Upgrades: Integrates AI interaction, 3D display, and other features to expand application scenarios (such as smart retail and virtual fitting rooms).
Indoor transparent LED screens, with their high transparency, energy-saving and environmentally friendly features, and creative display capabilities, have become an ideal choice for commercial spaces, cultural exhibitions, and stage performances. When selecting a product, you need to comprehensively consider pixel pitch, transmittance, brightness, and budget. Give priority to products with modular design and support for quick maintenance, and pay attention to the supplier's customized service capabilities.
