HL-251 Window Transparent LED Display | Bordeaux, France
In September 2025, VMX Visual successfully delivered a premium indoor transparent LED solution for a high-end retail window in Bordeaux, France. This case study explores how our HL-251 series combines aesthetics with performance.

Location: Bordeaux, France
Total Area: 12㎡ (6m x 2m)
Pixel Pitch: P2.6mm
Completion Date: September 2025
Series: HL-251 Aluminum Profile
Control System: NovaStar A5S Plus
1. High-Definition Visual Impact
The Bordeaux project utilized a P2.6 pixel pitch, providing exceptional clarity for close-range viewing in retail environments. With a 3840Hz refresh rate and 15-bit grayscale, the display ensures flicker-free video playback—crucial for high-end brand storytelling and smartphone photography by passersby.
Visual Performance: 800 nits brightness & 2000:1 contrast ratio ensure vivid colors even in bright indoor mall environments.
2. 55% Transparency for Natural Lighting
One of the primary requirements for this retail window was maintaining natural light inside the store. The HL-251 offers 55% transparency, allowing customers inside the shop to enjoy daylight while the exterior presents a futuristic, floating digital content effect. The ultra-slim 80mm cabinet ensures the display integrates seamlessly into the window frame without occupying valuable floor space.

3. Lightweight Aluminum Design
Constructed from premium Aluminum Profiles, each 1000x1000mm cabinet weighs only 12kg. This lightweight design significantly reduced the load on the building's glass structure and simplified the installation process.
- ✔ Energy Efficient: Average power consumption of only 200w/㎡.
- ✔ Easy Maintenance: Full rear access for both modules and power supplies.
- ✔ Reliability: IP20/21 rated for stable indoor operation with a 1-year warranty.
