COB Pro is not a generic fine pitch panel. It combines flip-chip COB technology with surface coating film, flexible architecture choices, and installation engineering that eliminates the pain points integrators actually deal with.
COB Pro ships with two Hub Board architectures — choose the integrated 3-in-1 Hub Board (receiving card + power + signal in one board, fewer internal cables, quicker assembly) or a separate receiving card design for integrators who prefer their own control infrastructure. The choice is yours at order time, and it does not affect cabinet dimensions or mounting hardware.
Installation complexity is where fine pitch projects often blow their budget. COB Pro addresses this with a no-weld custom back bracket — we engineer the bracket to your wall dimensions at the factory and it bolts together on site with standard fasteners. For 90° corners, the cabinet edges are CNC-cut at the factory for precision joins. For curved or arc installations, we provide custom connection plates matched to your radius. Every module is color-calibrated individually before shipping, and you get the calibration data with the shipment. White-label branding is standard — your logo, your packaging, your documentation.
Manufactured end-to-end in Shenzhen — PCB fabrication, flip-chip bonding, coating application, module assembly, calibration, and 72-hour aging — one factory, one point of contact, one warranty.

Seven Engineering Decisions That Make COB Pro the Right Choice
Design and manufacturing choices that matter to AV integrators — and why they matter to your end client.
Flip-Chip COB With Surface Coating Film — 10,000:1 Contrast, Dead-Flat Surface
LED chips are bonded directly to the PCB and encapsulated as a single surface — no individual LED lamp packages, no air gap between pixels. The surface coating film delivers a uniform matte black finish even when the display is off. This combination eliminates the glare and pixel-grid effect common in SMD fine pitch panels. The result is a 10,000:1 contrast ratio under EN 62977, with the coating providing additional protection against dust adhesion and minor surface abrasion.
3-in-1 Hub Board or Separate Receiver Card — Your Architecture, Your Choice
COB Pro offers two internal architectures: the integrated 3-in-1 Hub Board combines the receiving card, power management, and signal distribution in a single board — fewer cables, fewer connectors, fewer potential failure points inside the cabinet. Alternatively, choose the separate receiving card design if your project already standardizes on a specific control infrastructure. Both options share the same cabinet form factor, front-access service, and external mounting hardware. The choice does not affect lead time or minimum order.
Custom Back Bracket — No Site Welding, Bolts Together With Standard Tools
COB Pro ships with a custom-engineered back bracket system matched to your wall dimensions. No steel frame welding on site — the bracket sections are fabricated at our factory and bolt together using standard M8 fasteners. The bracket can accommodate uneven wall surfaces via adjustment points. We also produce custom connection plates for curved or arc splicing installations. Structural drawings are provided at no charge with every quotation. The bracket can be customized for any wall dimension.
CNC-Cut 90° Corners & Custom Arc Splicing — Creative Shapes Without Compromise
For L-shaped or corner installations, COB Pro cabinet edges can be CNC machine-cut at the factory to achieve precise 90° corner joins with no visible gap at the seam. For curved or arc installations, we supply custom connection plates engineered to your exact radius. These are not generic brackets bent on site — each plate is machined to the specified curve at the factory. Both CNC cutting and custom splicing plates are quoted per project and do not affect the standard lead time.
600, 800, or 1,000 Nits — Right-Size the Brightness to the Environment
COB Pro is available in three brightness tiers. 600 nits for controlled-lighting environments: control rooms, broadcast studios, and post-production suites. 800 nits for high-ambient indoor spaces: boardrooms with natural daylight, retail flagships, and museum galleries. 1,000 nits for maximum indoor brightness: glass-walled lobbies, atriums, and installations facing direct sunlight. Higher brightness draws more power and shortens LED lifespan incrementally — specifying the correct tier at order time avoids unnecessary operating cost over the display's 100,000-hour rated life.
Per-Module Calibration Before Shipping — Color Uniformity That Exceeds Industry Standard
Every COB Pro module is individually color-calibrated at the factory before shipping. Each LED chip's brightness and chromaticity coordinates are measured and corrected against a master reference, producing uniform output across the entire order — not just within a single batch. Combined with the surface coating film, this eliminates the visible color and brightness seams between adjacent cabinets that plague lower-tier fine pitch products. Calibration data is included with every shipment for your records and future service reference.

Where COB Pro Is Deployed
Six environments where the 16:9 native ratio, light weight, and front-access service deliver measurable project advantages.
Control Rooms & Command Centers
24/7 operation, 1–2m operator distance. Recommended: P0.78 or P0.9375 at 600 nits. Surface coating eliminates glare under overhead fluorescent lighting. Front-access service means maintenance without clearing the operator floor.
Broadcast & TV Studios
Camera-facing display at 1.5–3m. 7,680Hz refresh eliminates on-camera flicker and scan lines. 16:9 native matches broadcast resolution — no letterboxing or content cropping. Recommended: P1.25 at 600 nits.
Corporate Boardrooms & Conference Rooms
2–4m seating distance, mixed ambient light from windows. Recommended: P1.25 or P1.5625 at 800 nits. 16:9 native — content fills the screen without cropping. White-label available for integrator-branded installations.
Luxury Retail & Brand Flagships
High foot traffic, strong ambient light. Recommended: P1.5625 at 1,000 nits. Surface coating maintains a premium matte black appearance when off — critical for luxury brand environments. CNC-cut corners for L-shaped window displays.
Museums & Art Galleries
Close viewing for digital art and artifact displays. Recommended: P0.62 or P0.78 at 600 nits. The coating film's anti-glare property and uniform black surface are essential for art presentation. Custom arc splicing for curved gallery walls.
Virtual Production & XR Studios
LED volume for in-camera VFX. Recommended: P1.25 at 1,000 nits. 7,680Hz eliminates camera scan artifacts. Per-module color calibration ensures uniform background across the entire volume wall — critical when the LED surface is the background plate.

What's in the Box
Every COB Pro order ships pre-assembled and pre-calibrated. Here's what arrives on the pallet — nothing hidden, nothing to chase us for later.
COB Pro in the Field
Three documented installations that illustrate how integrators deploy COB Pro in demanding environments — and the engineering decisions that made each project work.
33sqm Immersive COB Showroom — 90° Seamless Corners
The 90° internal corner meant two physically obscured pixel columns at the seam — visible as dark lines with standard cabinet alignment. Required pixel-level offset mapping calibrated on each of the 20 Ethernet output cards, plus a custom CNC mounting framework with ±0.5mm per-axis adjustment at the corner plane intersection.
COB Pro P0.9 at 10,000:1 contrast. Custom NovaStar H9 configuration with pixel offset compensation. CNC-machined steel mounting frame. 3-in-1 Hub Board kept internal cabling manageable across 33sqm. Four-week total timeline from factory to calibrated display — over 40 million pixels.
"A 90° corner at sub-1mm pitch is one of the hardest things to get right in fine pitch LED. Two pixel columns physically disappear at the corner plane — misalignment by even half a pixel is visible from 1m. We ran calibration twice before signing off." — Kris Liang, Co-Founder
Custom P0.78 Hub Board — 7-Day R&D Turnaround
Custom PCB layout from scratch with non-standard signal routing. Only 7 days from requirement doc to delivered, tested board. If the board failed electrical validation, the client's project timeline had no buffer — zero margin for error.
DOIT VISION's 15-engineer R&D team designed, fabricated, assembled, and tested the bespoke hub board in 7 working days. COB Pro P0.78 module with custom pixel mapping delivered via a single purpose-built driver board. Passed all electrical and thermal validation on first iteration.
This case demonstrates what "Engineered for You, Not Off the Shelf" means in practice. When a client needs a hardware-level customisation on a tight timeline, DOIT VISION's 15 in-house engineers can go from napkin sketch to tested prototype inside a week — not as a special favour, but as standard R&D capability.
16×4 Cabinet Wall — Utility Control Center for Blue Rhine
Shallow 180mm wall cavity eliminated all rear-access cabinet options. Operators sit 1.5–2.5m from the wall — pixel pitch had to be fine enough for text legibility at close range. Overhead fluorescent lighting: glare and reflection on the previous DLP wall was a documented operator complaint. Client required 16:9 content alignment without cropping.
COB Pro P0.9375 at 600 nits. 16×4 cabinet array (9.6×1.35m, ~13m²). Front-access service eliminated the need for rear clearance. Custom no-weld back bracket engineered for the 180mm cavity with 4-point micro-adjustment per cabinet. Surface coating film eliminated the glare problem. 3-in-1 Hub Board kept cabling minimal with only 87mm of air gap behind the cabinets.
"The 180mm depth constraint is common in retrofit control rooms — the previous-generation DLP technology had different clearance requirements. COB Pro at 33mm cabinet depth plus a 60mm bracket left 87mm of air gap for cooling and cable management. Front-access meant we never had to open the rear, which in a 180mm cavity would have been impossible." — Kris Liang, Co-Founder
