COB LED Poster — Physical Overview
Available in 4 types across 3 display sizes. All types use COB flip-chip modules with aluminum die-cast construction and built-in Novastar/Colorlight media player.

Control Bay — Rear AccessWhat Makes COB Poster Different
The result is a 10,000:1 contrast ratio with 97% NTSC colour space coverage. 16 bit grayscale processing eliminates banding in gradients. Common cathode circuit design delivers up to 40% energy savings compared to conventional designs, with significantly reduced heat generation.
COB Poster is available in 4 types across 3 display sizes. Type A (600×1687.5mm) and Type B (600×2025mm) use 150×168.75mm modules in the same 600×337.5mm panel. Type C (640×1920mm) uses 320×160mm modules in a 640×480mm panel. Type D is identical to Type C with a foldable design for compact transport and storage.
All types ship fully assembled with lockable wheels. Plug into a 100–240V outlet and content plays via the built-in media player. Novastar ViPlex app for mobile content management. VNNOX Cloud for remote multi-unit publishing. Manufactured in Shenzhen. Shipped to 55+ countries.

Six Engineering Decisions That Make COB Poster the Premium Choice
Flip-Chip COB — Surface Sealed, Impact Resistant
LED chips bonded directly to the PCB, surface sealed with adhesive. The glue layer effectively reduces 99% of impact damage on pixels. No exposed wire bonds, no individual LED packages to dislodge. IP54 front protection against dust and water splashes.
10,000:1 Contrast · 97% NTSC · 16 Bit
COB encapsulation absorbs ambient light between pixels, delivering 10,000:1 contrast ratio. 97% NTSC colour space coverage. 16 bit grayscale processing ensures smooth gradient rendering. 600 nits brightness with colour temperature adjustable from 3,000K to 9,300K.
Ships Assembled — Built-in Media Player, Auto-Play
Every COB Poster ships with a built-in Novastar TB series media player running standard Android OS. Power on and it automatically plays default content. Update via USB stick, WiFi (ViPlex Handy app), HDMI, LAN, or VNNOX Cloud. Signal inputs: DVI, HDMI, SDI, AV, DP, VGA, YPBPR.
Flip-Open Edge — Seamless Multi-Unit Video Wall
The protective edge features a hinged design that flips open to eliminate visible bezels between adjacent units. Multiple posters splice into large-format video walls with coordinated content playback via Novastar Ethernet synchronisation.
Common Cathode — 40% Energy Savings
Common cathode circuit design with independent voltage per RGB channel eliminates waste heat from conventional common anode designs. Up to 40% energy savings. Power consumption: 350W max / 135W average per m². Passive cooling — zero fan noise, zero fan maintenance.
Type D — Foldable Design for Transport & Storage
Type D (640×1920mm) features a foldable design that reduces the unit to a compact form factor for transport and storage. Same COB display performance as Type C. Ideal for rental fleets, pop-up events, and installations that relocate frequently. Ships in carton, wooden case, or flight case.
Where COB Posters Excel
Luxury Retail & Flagship Stores
10,000:1 contrast renders jewellery and fashion photography with depth luxury brands require. IP54 surface withstands daily cleaning. COB impact resistance protects pixels in high-traffic showrooms.
Museums & Art Galleries
16 bit grayscale renders artwork gradients without banding. Zero fan noise — passive cooling. 600 nits brightness matches gallery lighting levels. Freestanding — no wall modification required.
Hotel Lobbies & Hospitality
Freestanding on lockable wheels. Built-in Android media player supports wayfinding, event schedules, and promotional content. Silent operation. VNNOX Cloud manages content across properties.
Corporate Reception & Showroom
VNNOX Cloud CMS pushes brand content to reception displays across all locations. 3,840 Hz refresh eliminates flicker on smartphone cameras. Easy content updates via ViPlex mobile app.
Exhibitions & Trade Shows
Multiple posters splice seamlessly via flip-open edge. Type D foldable design halves transport volume. Setup under 15 minutes per unit. Flight case packaging available.
AV Rental & Event Production
COB surface sealed with adhesive survives repeated transport. 99% impact damage reduction versus SMD. Type D foldable reduces storage and logistics costs for rental fleets.
