Unilumin Upad IV 500x500 mm die-cast magnesium rental LED cabinet

Unilumin Upad IV, UMicro COB & Usurface III Pro DOOH: Architecture & Technical Specifications

Beyond its core UGM II, URM III, and UGN II rental fleets, Unilumin’s display portfolio spans three specialized technology platforms: Upad IV ultra-light magnesium stage panels, UMicro flip-chip Micro LED COB fine-pitch walls, and Usurface III Pro high-brightness outdoor DOOH displays.

1. Upad IV Series — 6.3 kg Magnesium Frame & U-Shield Lamp Technology

The Upad IV indoor rental series (Upad IV 1.5, Upad IV 1.9, Upad IV 2.6) uses a 500×500×70.1 mm die-cast magnesium cabinet weighing just 6.3 kg (30% lighter than conventional aluminum cabinets). Tool-free rear module service takes 15 seconds, power box replacement takes 10 seconds, and the fast-lock angle block supports -5° (convex) to +10° (concave) curving (or ±40° when paired with flexible Upad IV-S cabinets).

Parameter (P2.6 Comparison) Unilumin U-Shield Lamp Traditional SMD1515 Lamp
Lamp Thrust Resistance 13 kg (130 N) — 5× stronger 2.5 kg (24.5 N)
Calibrated Brightness 1,600 nits 1,200 nits
Viewing Angle & Color Gamut 170° · 96% DCI-P3 160° · 90% DCI-P3

2. UMicro Series — Flip-Chip Micro LED COB with 30,000:1 Contrast

Designed for command centers, exhibition halls, industrial design studios, and luxury home theaters, UMicro combines RGB flip-chip COB packaging with common-cathode energy efficiency:

  • EBL+ (Enhanced Black Level+) & 3D-LUT: Multi-layer optical coating delivers a 30,000:1 contrast ratio, ultra-low moiré, and studio-accurate 3D-LUT color reproduction.
  • EDL Thermal & Energy Efficiency: Cuts power draw by up to 56% (on UMicro 0.7 vs. conventional 0.7 mm displays), keeping the front screen surface cool (~37°C at 600 nits in a 25°C room).
  • 5G Signal Bandwidth & Eye Comfort: 5G transmission quadruples data capacity per cable, while TÜV visual-comfort certification (<5% harmful blue light) and EMC Class B compliance suit close-viewing rooms.

3. Usurface III Pro — 10,000-Nit IP69K Outdoor Fixed DOOH

Unilumin Usurface III Pro outdoor fixed DOOH LED cabinet
Unilumin Usurface III Pro (800×900 mm profile aluminum cabinet with 400×300 mm dual-side potted modules).
  • 10,000 Nits & 5-Year Brightness Retention: Available in P6.67 / P8.33 / P10 (800×900 mm cabinet), maintaining 6,500 nits even after five years of outdoor operation, paired with ≥7,680 Hz refresh and 16,000:1 contrast.
  • DVPS 50%+ Energy Saving: Low-voltage DVPS circuit saves over 21,000 kWh across 3 years on a 50 m² billboard.
  • Vehicle-Grade IP69K & Dual-Side Potted Modules: Encapsulation glue boosts thermal conductivity 26× over static air, operating reliably from -40°C to +60°C in coastal salt-spray and hurricane environments.
