Pixels
Pixel-to-pixel spacing ranges from 3.906 to a very compact 2.604 millimeters to create high-resolution displays that align up to 147,456 SMD lamps into a single square meter.
Each millimeter of spacing supports one meter of viewing distance which means that the QF Series will look great from less than 3 steps away.
Dimensions
The QF Series is a unique solution for creative displays. Each module weighs less than 1 kilogram with x·y·z dimensions of 250 × 250 × 62 millimeters and connected to a power box.
Standard and custom cabinets are built to your specifications and can be machined using CNC to create a precise concave or convex display surface for your project.
Schematics
We provide our Engineers with a detailed description of your project. They provide mechanical and electrical drawings based on your Desay Series selection and configured to best match the parameters of the installation.
Those drawings are generated in industry-standard Adobe PDF and Autodesk DWG formats to share with your team.
Lamps
The QF Series is equipped for indoor or outdoor applications with 3500 to ≥ 6,000 candelas/m2 of fully-adjustable brightness from Nationstar and Kinglight SMD lamps.
Refresh rates are set at up to 7680 Hz for broadcast video. 160° of indirect viewing means that everyone in your audience can see the QF Series whether they are coming or going.
Options
Once you have selected a Desay Series display that provides the resolution and brightness you need for your target audience, we have a short list of options to consider.
We offer custom panels with corners and contours, frames and rigging, spare components and warranty extensions. Pretty much anything you need. Just ask.
Installation
QF Series modules are magnetically attached to your custom cabinet or to a unique steel surface of your design and connected to a remote power box.
Follow any concave or convex line, wrap around a corner or a column, or fill out a simple rectangle within a cabinet secured to a lightweight frame bolted to a wall.
Cards
The QF Series relies on NovaStar's Armor and COEX receiver cards combined with Vision Management Platform software to provide Dynamic Booster, Full Grayscale Calibration and Image Booster functions to your display.
VMP supports Image Enhancement and frame-by-frame Pixel Analysis to reduce power consumption by >20%.
Quotes
We love to provide quotes for clients, so don't hesitate to ask. Formal quotes can typically be ready for your consideration within a few hours.
At your request we can review your project with factory technicians to offer suggestions on solutions specific to your project. The rest is mostly just shipping details.
Performance
Every redn × greenn × bluen lamp creates many times more color combinations than our eyes can see, along with an abundance of silky smooth shades of grey.
Display life is projected to be 100,000 hours or about 11 years of full-time use. Which means we look forward to hearing from you again sometime in 2037.

Pixel Pitch · 2.604
Pixel pitch, measured in millimeters, is the distance from the center of one LED pixel to the next, determining image clarity, resolution, and optimal viewing distance. The industry rule of thumb is that for every millimeter of pixel pitch, the corresponding viewing distance is one meter. A pixel pitch of 2.604 is best viewed from 2.5 meter or more for optimal results. Calculate pixel density by dividing 2.604 into 1000 millimeters for 384 pixels per linear meter. Square this result for a product of 147,456 pixels per square meter and multiply by your display height and width to determine your total resolution.

About Desay
Desay Opto: A Global Leader in Optoelectronics
Desay Opto, a public corporation (002920) with a nine billion dollar market valuation, has quietly emerged as an industry leader in the optoelectronics sector. Ranked #1 in Asia and #3 worldwide for the past decade, Desay's Optoelectronic division has achieved remarkable success, with annual sales measured in tens of thousands of panels and cabinets.
Extensive Manufacturing Capabilities
Desay boasts three industrial zones with a total area exceeding one and a half million square meters. The company's headquarters, factory, and offices are located in Huizhou, with additional offices in Shenzhen. This extensive manufacturing footprint enables Desay to develop and produce some of the highest-quality LED displays in the world, earning the company a well-deserved reputation for excellence.
Cutting-Edge Technology
Desay's success is driven by its leading technology in Optoelectronic Control and Non-linear Alignment Techniques. By combining these technologies with rapid image compensation and point-to-point image data processing technology, Desay balances the light intensity of the frame, creating vivid pictures and distinct gradations. This results in an immersive experience for viewers, both indoors and outdoors.
Moreover, Desay has developed and patented the most advanced pixel enhancement technique in the industry. This system can improve the resolution of a full Desay display by a factor of four without degrading the contrast, further enhancing the visual experience.
Uncompromising Quality
Desay understands that cutting corners on build quality can have long-term consequences. While some manufacturers may opt for low-grade two-layer PCBs with tin plating and flammable materials to reduce costs, Desay chooses four- to six-layer boards with gold plating and fire retardants. This commitment to quality ensures that Desay's displays are not only superior but also safer, longer-lasting, and require less service, ultimately providing greater value to customers.
As Sir Henry Royce famously said, "The quality will remain long after the price is forgotten." Desay's advanced engineering and precise manufacturing processes result in outstanding products that embody this philosophy, solidifying the company's position as a global leader in optoelectronics.

Frequently Asked Questions
Telematics Canada Inc. is an authorized factory distributor for Huizhou Desay Intelligent Technology Co., Ltd. and Xi'an NovaStar Tech Co., Ltd..
With over 25 years of operation as a federally incorporated Canadian entity, we serve as the direct commercial link between the manufacturer and the North American market. We provide the legal standing for contracts, import logistics, and authorized warranty execution for both brands.
What do you need? And what do you want?
You need a high-performance, high-quality LED display at a price that meets your budget.
You want it delivered sooner, not later. You want the installation to go smooth and fast and deployed without headaches.
And you need your investment to be backed by a solid warranty from a world-class manufacturer with local support from a domestic distributor.
Which is exactly what we offer.
When do you need it?
With few exceptions, every Desay Series display is custom-built for your specific project. This takes time, but the schedule is precise.
We design the display to match your exact installation parameters, generating schematics and wiring diagrams for your approval.
Manufacturing, performance testing, and packaging require three to four weeks. Freight adds one week by air or one month by sea. Also, China has a generous number of holidays throughout the year that can delay production scheddules.
With more than 20 years experience with this process, our advice is always the same: do not wait until the last minute before ordering.
So far, no one has taken our advice.
Where is everyone?
Don't you hate trying to figure out where everyone you want to work with is located? Why is that ever even a question?
Telematics Canada has offices in Vancouver, BC and in Montreal, QC, Canada. Our full contact information is at the bottom of every page.
Desay Optoelectronics designs, develops, and manufactures the Desay Series in Huizhou City and Shenzhen, Guangdong Province, China.
Xi'an NovaStar Tech Co. designs and develops their control architecture at the Nova Science and Technology Park in Xi'an, Shaanxi Province, with additional direct sales and logistics operations in Shenzhen, Guangdong Province, China.
We look forward to hearing from you.
Why are we meeting like this?
Chances are you have followed a link to our site that started with a search for LED display systems or distributors, and some other terms that landed us on the front page.
We recently asked Gemini Deep Research: What is the current estimated number of LED display manufacturers in China?. Here is a snippet of that response:
Mapping the Specialized Manufacturing Tiers
I have successfully categorized the Chinese LED display industry into a defined hierarchy, identifying a core group of approximately 1,000 specialized manufacturers. While regional registries in hubs like Shenzhen often list over 10,000 LED-related entities, I've distinguished that the specialized display market consists of roughly 10-20 top-tier global leaders, followed by 100-200 mid-sized professional manufacturers, and a broader base of roughly 800 smaller assembly-focused shops. I’ve also clarified corporate structures, such as ROE Visual's position as a premium arm of a larger conglomerate and the specific optoelectronic focus of groups like Desay, to ensure the census reflects true full-service providers.
The number of choices in this industry is daunting. And only a handful of these manufacturers will be operating a decade from now.
With a market capitalization of 10 billion USD, Desay is one of those top-tier companies.
We look forward to hearing from you.
How do we proceed?
Our first step should be an introduction to your Team, or at least those tasked with initiating the project.
We can do so with a spontaneous phone call or schedule a Teams or Zoom meeting if that is your preference.
We will need to know if this will be (✓) an indoor or outdoor LED display, (✓) how close your audience will be, if the display is (✓) a permanent or temporary installation, and (✓) how soon do you need your LED display up and running.
With this information, we can quickly generate an estimated price range for your consideration and go from there.
We look forward to your call.
