The T3 Display System.
Invented. Patented.
Manufactured by T3 Systems.
T3 Systems (Tecna Display Ltd) is the original inventor, sole patent holder and exclusive manufacturer of the T3 Twist & Lock modular display system. Founded in Harlow, Essex in 1981 by Jonathan Evitt. 30+ granted patents. Two Queen's Awards for Enterprise. Every genuine T3 component is made at our own facilities in Harlow and Trappes, France. From a compact shell scheme upgrade to a full custom island stand.
Other companies may use T3 components to build exhibition stands for their clients. They are resellers and contractors. They do not manufacture T3. When you work with T3 Systems directly, you work with the people who invented, patent and build the system.
Jonathan Evitt Invented
the T3 System in 1981.
"I designed the original T3 connector in Harlow in 1981. The problem I was solving was simple: every display system at the time required tools and specialist labour to assemble. I wanted a system that anyone could build, that could be reconfigured into any shape without fixed sizes or fixed angles, and that could be reused indefinitely. The Twist & Lock connector was the solution. Everything T3 has built since — the curves, the LED integration, the shell scheme system — comes from that original connector design. We have protected it with 30+ patents across Europe, the USA and China. It is the only system of its kind."— Jonathan Evitt, Chairman & Founder, Tecna Display Ltd · Inventor of the T3 system · Harlow, Essex, 1981
Jonathan Evitt is the Chairman and Founder of Tecna Display Ltd, the legal entity behind T3 Display System Manufacturers. He designed the original T3 Twist & Lock connector at the company's Harlow, Essex facility in 1981 and has since developed the system into a globally patented portfolio of 30+ granted patents — covering the core connector mechanism, the tool-free locking action, the curve engineering capability, the T3 Wandlight 360° integrated LED system and the T3 Affinity conference infrastructure system.
T3 Systems is not a reseller. It is not a contractor. It is the company that invented the T3 system, holds every patent on it, and manufactures every T3 component at its own facilities in Harlow, Essex, UK and Trappes, Île-de-France, France. Delivered directly to Edinburgh EICC, SEC Glasgow, Bristol, NEC Birmingham and every UK venue. Jonathan and the T3 team are the people you deal with when you work with T3 Systems directly. There are no agents, no intermediaries, no markup on someone else's product.

"When clients ask me why they should work with T3 Systems rather than a contractor who uses T3 — the answer is always the same. We're the people who made the thing. When you need something custom, we solve it at a component level because we manufacture every component. When you need a shell scheme upgrade in Edinburgh tomorrow, it ships from our own stock. When something doesn't work, we fix it because we built it. A reseller's best day is our every day."— Philippe Van Ameyde, Managing Director, Tecna Display Ltd

30+ Granted Patents.
Europe. USA. China.
Tecna Display Ltd holds 30+ granted patents protecting every core aspect of the T3 system. These are not pending applications — they are granted, in-force patents across the world's three major patent jurisdictions.
The Twist & Lock Connector
The core patent — protecting the mechanism by which T3 aluminium profiles insert, twist 90° and lock without tools. The connector that makes the entire system possible — from a shell scheme upgrade to a full island stand. Granted across Europe, USA and China.
Curve Engineering
Patents protecting T3's curve capability — the method by which standard T3 profiles are machined to produce genuine custom curves to 0.5mm tolerance. No other modular display system has this. No competitor holds equivalent patents. Used by Duca del Cosma at PGA Orlando and for luxury retail displays.
T3 Wandlight — 360° LED
The world's first patented 360° LED tube for modular displays. T3 Wandlight integrates directly into the aluminium profiles. 70,000hr lifespan, IP65 rated, RGB. Used in every backlit exhibition stand. Patented internationally.
⚠️ Important: The T3 Twist & Lock system is a globally patented, internationally trademarked framework. All genuine T3 components are manufactured exclusively by Tecna Display Ltd. T3 Systems is the sole authorised source of T3 components, datasheets and technical specifications.
