|---|---|---|---|
| Photos |  |
 |
 |
| Structure | Rigid aluminum frame, modular panels | Flexible film (rollable), adhesive-backed | Hollow PCB with LED chips, bendable |
| Transparency | 70%+ | 90%+ | 80%+ |
| Pixel Pitch (mm) | P2.6-P15.6 | P5, P6.25, P8, P10, P15, P20 | P2.91, P3.9, P6.25, P7.8 |
| Brightness (cd/m²) | 1000-5000 | 2000-4000 | 3000-4500(adjustable) |
| Installation | Requires structural support | Self-adhesive (sticks to glass) | Stick to glass or compatible surface by Adhesive tape |
| Application | Indoor or Outdoor. By using recommended or provided frame or hanging rod, it can be hanging from ceiling, or fixed to wall, or floor-standing. | Indoor, with gel covered, the LED film surface is waterproof, it can be directly sticked behind Glass by side of street. | If it is a glass window close to the street and is exposed to direct sunlight for a long time, we do not recommend installing this product directly by pasting, because the lamp beads are exposed and the temperature difference between morning and night will produce water vapor, which will cause damage to the LED lamp beads over time. You can install it by adding the recommended simple profile frame and hoisting crossbar, etc. |
| Maintenance | You can remove the small module with the bad light and repair or replace it. Easy to handle with. | You must remove the entire LED film and replace it with a new one, send the defective product back to the manufacturer or find a local technician for repair. And Be very careful when taking the product off. | You must remove the entire LED film and replace it with a new one, send the defective product back to the manufacturer or find a local technician for repair. It takes some effort. |
| Re-usable | If it is a rental box, it has a quick lock and can be quickly installed and disassembled. | Do not remove and stick it repeatedly, as this will cause the gel layer on the surface of the product to lose its stickiness. | The product is attached to the surface with double-sided tape, and can be removed and reused with care. |
| Waterproof | Outdoor (IP65) & indoor options | Indoor only (non-waterproof) | Indoor only (non-waterproof) |
| Max Size (H x W) | Unlimited (modular) | Max 1450mm (W), 2pcs can get 2900mm max. | Max 1500mm (W) /pc ,2pcs can get 3000mm max. |
| Flexibility | Rigid, flat or curved (limited) | Highly flexible (conforms to curves) | Bendable (but less than film) |
| Price | Low (cost-effective) | High | High |
2. Selection Recommendations
✅ Choose Product 1 (Modular Transparent LED Panel) if:
-
Large-scale installations (unlimited size via modular assembly).
-
High brightness needed (up to 5000 nits for outdoor/sunlight use).
-
Budget-friendly (best cost per square meter).
-
Outdoor/indoor flexibility (IP65 waterproof option available).
-
Stable, rigid installation (fixed structures like building facades, stages).
Best for:
✔ Shopping mall displays
✔ Stage backdrops
✔ Outdoor advertising (bus stops, building facades)
✅ Choose Product 2 (LED Film Screen) if: 
-
Ultra-high transparency (90%+) is critical (e.g., retail windows).
-
Flexible & curved surfaces (wraps around glass, columns).
-
Quick installation (self-adhesive, no heavy structure needed).
-
Sleek, seamless appearance (minimal visible hardware).
Best for:
✔ Luxury retail (window displays)
✔ Museum/exhibition interactive screens
✔ Indoor curved installations (cylinders, arches)
✅ Choose Product 3 (Hollow PCB Film Screen) if:
-
Higher resolution (P2.91,P3.9, P6.25, P7.8) + high brightness (3000-4500 nits) is needed.
-
Good balance of transparency (80%) and image quality.
-
Lightweight and flexible for curved and large panels (better than film for a little bigger sizes and higher resolution).
-
Indoor high-end displays (no outdoor use).
Best for:
✔ Corporate lobbies (high-resolution video walls)
✔ High-end retail (product showcases)
✔ Indoor events (conferences, exhibitions)
3. Key Decision Factors
| Priority | Best Choice |
|---|---|
| Lowest cost | Product 1 (Modular Panel) |
| Highest transparency | Product 2 (LED Film) |
| Best image quality | Product 3 (Hollow PCB Film) |
| Outdoor use | Product 1 (IP65 version) |
| Easiest install | Product 2 (Self-adhesive) |
| Large-scale | Product 1 (Modular scalability) |
Final Recommendation
-
For budget-friendly, large-scale, or outdoor projects → Product 1
-
For ultra-transparent, flexible, and quick-install solutions, storefront windows indoor displays → Product 2
-
For high-resolution, bright, and quick-install solution indoor displays → Product 3
Some Facts for Screen Brightness Selection
For indoor LED transparent screens, the required brightness varies depending on the environment:
-
Indoor (near street-facing windows with direct sunlight): High-brightness indoor transparent screens are needed, with a brightness of >4000 cd/m² or higher.
-
Brightly Lit Indoor Spaces (e.g., Shopping Malls, Airports,Showrooms)Recommended Brightness: 2,000–3,000 cd/m².
-
Standard Indoor Lighting (e.g., Offices, Meeting Rooms, Retail Stores)
Recommended Brightness: 600–1,500 cd/m² -
Dim environments (e.g., Bars, Theaters, Dark Rooms) Recommended Brightness: 300–500 cd/m²
Why? In dimly lit spaces, overly bright screens can cause discomfort. Lower brightness ensures a balanced viewing experience.
For fully outdoor applications, brightness requirements vary based on usage type:
-
Rental transparent screens (short-term use, e.g., events): Typically require a brightness of 5000 cd/m².
-
Permanent Outdoor Installations (e.g., Building Facades, Billboards, Stadiums). Recommended Brightness: 7,000–10,000+ cd/m².
Key Considerations When Choosing Brightness
✔ Energy Efficiency – Higher brightness consumes more power. Balance visibility with cost.
✔ Viewing Comfort – Excessively bright screens in dark environments cause eye strain.
✔ Content Type – Video ads may need higher brightness than static text/graphics.
✔ Day/Night Mode – Smart displays can auto-adjust brightness to save energy.
Conclusion
-
Indoor: 300–5,000 cd/m² (depending on ambient light).
-
Outdoor: 5,000–10,000+ cd/m² (higher for direct sunlight).
-
Adjustability: Opt for displays with brightness control for flexible use.
