YOUR CUSTOM
LED DISPLAY PARTNER.
19 years of LED engineering. Direct founder access. Custom R&D. We are a boutique LED display manufacturer in Shenzhen, built for AV integrators and rental companies who need a partner that responds fast, engineers custom solutions, and actually answers the phone.
19 YEARS.
ONE MISSION.
“When you work with DOIT VISION, you don’t talk to a sales rep. You talk to the engineer who designs your solution. That’s the difference between a supplier and a partner.”
Kris Liang started in LED manufacturing in 2007. Over 19 years, he worked on the 2008 Beijing Olympics floor screen (3,000 sqm, P20.83), led a USD 2M+ broadcast display project for an Italian TV network, delivered the Israel Pavilion at the 2015 Milan World Expo, and developed the Matrix rental series — 20,000+ cabinets across 20 countries.
In 2017, he acquired a Shenzhen LED manufacturer (est. 2013), rebranded it as DOIT VISION, and rebuilt it around a single purpose: to be the engineering partner that international AV integrators and rental companies could not find anywhere else.
Direct access to the decision maker. No layers. No “let me check with management.” When you need a technical answer, you get it same-day.
Honest technical advice. We will tell you when P1.5 is the right answer instead of upselling P0.9. That builds partnerships that last 20 projects, not just one.
Free pre-sales support. CAD drawings, 3D mockups, technical proposals — at no cost for qualified projects. We invest before you commit.
WHAT MAKES US
DIFFERENT.
Custom R&D — Engineered for You
We do not just sell from a catalog. Custom PCB design, bespoke cabinet structures, custom pixel pitches — these are our daily work, not exceptions. From concept sketch to mass production, one team handles it all.
Direct Founder Access — No Middle Layers
When you message DOIT VISION, you reach Kris Liang or a senior engineer directly. No sales scripts. No ticketing queues. Same-day WhatsApp response, same-afternoon CAD file if needed.
Shenzhen Speed — Without Compromises
We leverage Shenzhen’s unparalleled supply chain — PCB fabrication, aluminum die-casting, CNC, tooling — all within a 30km radius. Prototype in weeks, not months. Paired with CE/EMC/RoHS-certified quality.
Boutique Partnership — Not a Number
We deliberately stay at 15 core engineers. Past 50, bureaucracy starts. Past 200, you become the factory that ignores a client’s custom CAD. Small enough to care, strong enough to deliver.
HOW WE WORK
WITH YOU.
Inquiry & Consultation
Send your project brief via WhatsApp or email. Within hours, an engineer responds with specific technical questions. This is a real engineering conversation from message one.
Design & Proposal
We create CAD drawings, 3D renderings, and a detailed technical proposal. For custom shapes, our R&D team designs PCB layouts and mechanical structures.
Prototype & Approval
We build a working prototype. You review it by video call, photos, or a visit to our Shenzhen facility. We iterate until you are satisfied.
Production & QC
Production with multi-stage QC: incoming inspection, 48-hour burn-in on every cabinet, final performance check. You receive QC photos and videos throughout.
Delivery & Support
We handle export packaging, documentation, and freight coordination. Post-delivery, you still have direct WhatsApp access to our engineers.
WHO WE SERVE
— AND WHO WE DON’T.
AV Integrators
You are the project lead. We are your engineering back-end. We provide the custom LED displays, CAD drawings, and technical depth you need to win bids and deliver flawless installations — without ever competing against you for the end client.
Our Approach
- Free pre-sales CAD, 3D mockups & bid-ready documentation
- Same-day WhatsApp response from Kris Liang or senior engineers
- White-label / OEM as standard — your brand, your client
- Integrator-tier pricing — we grow when you grow
Rental Companies
Your reputation depends on every show going flawlessly. We engineer rental LED cabinets that are lightweight, fast to deploy, and rigorously tested — with spare parts always in stock and engineers on standby when you need them.
Our Approach
- Lightweight quick-lock cabinets — designed for touring speed
- 48-hour burn-in on every single cabinet before shipping
- Guaranteed spare parts programme — no waiting, no downtime
- Brompton & Novastar pre-calibrated — ready to plug and play
NUMBERS

Two Locations.
One Mission.
Our headquarters and factory operate side by side in Shenzhen’s Guangming District — the global capital of LED manufacturing. Engineering happens at HQ. Production happens at the factory. You get direct access to both.
FROM SHENZHEN
TO THE WORLD.
We ship from Shenzhen — the global capital of electronics manufacturing — to integrators and rental companies across 55+ countries. Our team speaks English and Chinese fluently. We understand the certification requirements, voltage standards, and logistics for each region we serve.
Not in these regions? We ship globally. Contact us to discuss your location and requirements.

QUESTIONS
WE HEAR OFTEN.
DOIT VISION is a boutique LED display partner, not a mega-factory. Three things set us apart: (1) Direct founder access — you communicate with Kris Liang, our co-founder with 19 years of LED engineering experience, not a sales rep. (2) Custom R&D capability — we design custom PCBs, structures, and firmware for bespoke projects that large factories reject. (3) Shenzhen speed — same-day technical response, fast prototyping, on-time delivery.
Yes — custom LED displays are our core capability, not an afterthought. We handle custom PCB design, bespoke cabinet structures (spheres, curves, halos, multi-sided pillars), custom pixel pitches, aluminum die-casting, and full NPI from concept to mass production. Unlike mega-factories that require minimum order quantities in the thousands, we take on custom projects of all sizes. Every custom project ships with full CAD drawings and structural documentation.
Standard product orders ship within 15–25 days. Custom projects with new PCB design take 30–45 days from design freeze. Custom tooling (molds, dies) adds 25–35 days. The key advantage is our streamlined communication — when you message us at 10am China time, an engineer answers by noon. No approval chains, no ticketing queues.
We primarily serve four key regions: North America, Europe, Southeast Asia, and East Asia (Japan and Korea). Our products have been shipped to 55+ countries. We understand the specific certification requirements, voltage standards, and logistics for each region. Our team communicates in English and Chinese.
DOIT VISION products carry CE (European Conformity), EMC(Electro Magnetic Compatibility Certification), RoHS (Restriction of Hazardous Substances), and CB (IECEE CB Scheme) certifications. We can also arrange additional regional certifications (e.g., ETL for North America, PSE for Japan) for qualified projects.
The fastest way is to message us on WhatsApp at +8618665800742. Kris Liang or a senior engineer will respond same-day during business hours (9AM–9PM China Time). You can also email info@doitvision.com with your project brief. We provide free pre-sales CAD drawings and 3D mockups for qualified projects, typically within 48 hours.
Absolutely. Small and medium-sized AV integrators are our ideal clients. Mega-factories often require minimum order quantities that smaller integrators cannot meet. DOIT VISION was built specifically for integrators who need a responsive, technically capable partner — regardless of project size. We offer integrator-tier pricing, white-label/OEM options, free bid support, and we never compete directly against our integrator partners.
DOIT VISION LED displays are compatible with all major control systems:Novastar, Colorlight and Linsn. We pre-configure RCFG files and provide full calibration support for your chosen system.
