A commercial display manufacturer commissioned 1,500 round Android advertising displays for luxury hotels, where each screen doubles as a decorative mirror when idle. Sanjun built circular bezels with mirror-grade anodized finishes, IP54 sealing and slim 12mm profiles.

From initial concept to final delivery –every detail of this custom fabrication project
As luxury hotels prioritize immersive guest experiences, a leading commercial display manufacturer launched a 2026 program for 1,500 round Android advertising displays in 18.5-inch and 23.8-inch sizes. Active, they show promotions, wayfinding and event content; idle, they read as decorative mirrors.
The project demanded circular precision, mirror-grade reflectivity, and durability in high-humidity hotel areas such as bathrooms and lobby corridors.
A display that doubles as a mirror leaves no room for imperfection: a gap, a warp or a fogged surface breaks the illusion instantly.
The two hardest hurdles were circular precision and mirror finish. Any gap between bezel and panel spoiled both the look and the mirror effect, while conventional polishing risked warping the thin aluminum and distorting reflection.
Sanjun laser-cut the circular bezel and rear box with a dedicated dust-collection system to keep the mirror surface contamination-free. A 7-axis press brake with custom circular jigs formed the slim profile, and a two-stage mechanical plus chemical polish under vacuum clamping held flatness below 0.1mm/m2 before two-step anodizing delivered 92% reflectivity and a 4H scratch topcoat.
Integrated silicone gaskets, lower drainage grooves and a breathable waterproof membrane achieved IP54 in humid bathrooms, while SPC sampling every 50 units kept reflectivity and concentricity consistent across the full 1,500-unit run.
All 1,500 units in both sizes shipped five days early with a 100% pass rate on roundness, reflectivity, IP54, 15kg bracket load and 1,000-hour humidity cycling tests.
After seven months across 80-plus luxury hotels, the client reported a 22% rise in guest display engagement and a 15% drop in maintenance calls, then signed a two-year partnership covering three new round display series.
When the screen is off, guests genuinely see a mirror. Sanjun’s circular precision and mirror-surface technology let us deliver a product that luxury hotels actually want on their walls.
