LED DISPLAY MANUFACTURER
YOUR ENGINEERING PARTNER.
DOIT VISION partners with AV integrators and rental companies worldwide — COB, MIP, rental, outdoor, and custom LED video walls, from engineering and structure to installation support.
More Than a Screen Supplier — Your Engineering Partner.
Most manufacturers hand you a panel and walk away. We stay. From the first technical question to final installation, DOIT VISION’s in-house teams cover the full stack for permanent LED video wall and fine pitch display projects — so your project ships on time, performs reliably, and looks exactly as designed. We help partners enter the LED business from the ground up, and grow with you project after project.
Electronics
In-house driving & control engineering for stable, high-grade image performance.
Structure
Custom mechanical and cabinet design for any shape, weight, or install condition.
Installation
On-site guidance and technical support to get every project right the first time.
Partnership
Long-term collaboration — from your first order to building a business together.
WE DON’T COMPETE ON BEING THE BIGGEST FACTORY.
We compete on being the smartest choice for your LED video wall project. Here’s how a 15-person boutique engineering team — backed by a 60-person operation — outperforms a 5,000-person mega-factory for the AV integrators who have to deliver.

Learn More →We Build What Others Can’t.
Curved, spherical, cylindrical, triangular, floor-to-ceiling — if you can draw it, our engineering team can build it. Custom-shaped and creative LED installations are where DOIT VISION stands apart from every standard catalogue manufacturer.
And here’s what that means for you: if we can master the most complex architectural geometries with <0.5mm seam tolerances, your standard flat-panel project is in exceptionally capable hands.
Brought to us by architects, designers, and integrators who refused to hear ‘that can’t be done.’

SPEC YOUR DISPLAY
IN 60 SECONDS.
Our professional LED calculator does what no spec sheet can — it calculates pixel pitch from viewing distance, panel count from screen dimensions, total power draw, and estimated weight for your exact configuration.
Covers all DOIT VISION product lines: COB Pro, MIP, Matrix 500, Block, Brick, Lite, Flex, Outdoor FO Series, and custom pitches.
Pixel Pitch Finder
Input viewing distance → get recommended pixel pitch range with COB / MIP / SMD guidance.
Cabinet Counter
Enter screen width × height → exact cabinet quantity, with real model dimensions from our catalogue.
Power Calculator
Total max & average power draw per your configuration — for venue power planning and proposals.
Weight Estimator
Total system weight for rigging load calculations — real figures, not estimates.

DOIT VISION is a 15-engineer boutique team — part of a 60-person operation — founded in 2013 and relaunched in 2017 by Kris Liang with a sole focus on overseas markets. Unlike mega-factories, we offer direct engineer-to-engineer communication, same-day technical response, custom CAD and 3D mockups for bid support, integrator-tier pricing, and full white-label support — without the organizational friction.
SMD (Surface-Mount Device) is the most common LED technology — reliable and cost-effective for standard applications. COB (Chip-on-Board) bonds chips directly to the PCB, delivering 5H surface hardness, true blacks (10,000:1 contrast), ~40% energy savings vs SMD, and 4K camera compatibility — ideal for control rooms and broadcast. MIP (Micro LED in Package) adds 7,680Hz refresh, HDR10, and 21-bit grayscale — the choice for HDR-critical production environments.
Standard SKUs: 15–25 days. Custom projects (spheres, curved walls, multi-sided pillars, holographic): 4–6 weeks after CAD approval. Rush production has been achieved in 3 weeks for event-critical projects. We provide firm written lead-time commitments at quote stage.
Rule of thumb: viewing distance (metres) ÷ 1000 = recommended pitch (mm). Control rooms at 2–4m → P1.2–P1.8 COB. Corporate lobbies at 4–8m → P2.5–P3.9. Large venues 8m+ → P4–P6. For close-viewing or immersive environments, COB at P0.6–P0.9 eliminates moiré and grain visible on SMD at the same distance.
Yes. Pre-sales CAD drawings, structural calculations, 3D mockups, and itemized technical proposals are provided free of charge for qualified projects — in white-label and renamed versions. This is a core part of how we help integrators win bids, not an upsell.
Yes. All DOIT VISION panels ship pre-configured for your specified control system — Brompton Tessera, Novastar MCTRL series, or Colorlight Z-series. Configuration files are included on USB with every shipment. For complex multi-zone installations, we test the full system before crating.
Yes. Renamed spec sheets, white-label datasheets, OEM-branded packaging, and OEM serial numbers are available for qualified integrator partners. Your end client does not need to know our identity. A dealer program with integrator-tier pricing is available for serious partners.
All DOIT VISION products carry CE, FCC, and RoHS certifications. Our facility is ISO 9001 certified. Product-specific test reports (EMC, LVD, REACH) are available on request for EU project submissions.
