21.5-Inch 4K High-Brightness Hanging Digital Signage Deployed Across Europe

Project Case

Location: Multiple countries across Europe
Quantity: 1000 Units
Product Model: 21.5-Inch Hanging Window Digital Signage Display (4K, 1500–2500 nits)

✅ 1. Project Background

Retail chains and fast food brands across Europe are increasingly turning to digital window signage to capture customer attention in high-traffic areas. A group of clients—including supermarkets, cafés, and QSR (Quick Service Restaurants)—sought a sunlight-readable display solution for window-facing advertising. They required a digital menu board or promotional screen that not only looked premium but could also withstand the challenges of glass storefront environments.

✅ 2. Key Challenges

• Poor visibility in direct sunlight, especially during midday hours

• Limited display flexibility, as many screens couldn’t support portrait/landscape switching

• UV and IR exposure through glass windows caused long-term damage and screen discoloration

• Excessive heat buildup, which affected performance and product lifespan

• Complex installation, especially for stores needing multiple screens in a clean, cable-free format

✅ 3. CNLC’s Solution

• Supports both landscape and portrait installation, fitting various use scenarios

• Modular cascading setup: up to 4 screens in a row, ideal for window-wide promotions
