When selecting a transparent LED display, key factors include transparency, installation environment, pixel pitch, brightness, flexibility, and budget. Below is a detailed comparison of the three products and recommendations for different scenarios.

1. Product Comparison Summary

Feature	Product 1: Modular Transparent LED Panel	Product 2: LED Film Screen (Flexible PET/PI)	Product 3: Hollow PCB Film Screen (Holographic LED Film)
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-P20	P3.9-P7.8
Brightness (cd/m²)	1000-5000	2000-4000	3000-5000(adjustable)
Installation	Requires structural support	Self-adhesive (sticks to glass)	Stick to glass or compatible surface by Adhesive tape
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 (P3.9, P6.25, P7.8) + high brightness (5000 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

Final Recommendation

• For budget-friendly, large-scale, or outdoor projects → Product 1

• For ultra-transparent, flexible, and quick-install solutions → Product 2

• For high-resolution, bright, and quick-install solution indoor displays → Product 3
