YES TECH, a specialized and innovative “little giant” enterprise from the Jinxiang Economic Development Zone with 22 years of experience in the field of LED display screens, impressed the world through the stage art at the opening ceremony of Hangzhou Asian Games, the stunning main stage of the Las Vegas World Immersive Spherical Metaverse Experience Center that has sparked discussions online, and the recently concluded G20 Summit in India that captured global attention.

On October 18, YES TECH unveiled two new products of the outdoor fixed installation Mview series and the fine-pitch Obsidian series, further promoting the extensive application of LED display screens in emerging scenarios such as commercial premises, cultural tourism venues, sports complexes, and metaverse space.

Display screens are products with a high frequency of updates and iterations. The R&D engineers have to consume a lot of time and energy to develop a product to meet the needs of customers.

Wang Chang, a senior electronic R&D engineer at YES TECH, returned to Changsha from Shenzhen in 2011 and joined the company in the same year. “I consider myself quite fortunate. Shortly after joining the company, I got involved in the R&D of LED curtain wall screens.”

In 2011, the R&D engineers at YES TECH were busy working in the office in the early hours of the morning because a South Korean client requested them to develop a lightweight, thin, and durable display screen. However, this seemingly ordinary request actually subverted the industry’s traditions.

“How can we ensure the stability and reliability of the product after replacing the traditional metal box structure?” Engineers came up with an idea: why not change soft electrical connections to hard electrical connections? By innovating the connection structure, they aimed to create a lightweight and stable display screen with strong performance without increasing costs or prices.

At the time, it seemed like a fantasy, but the engineers at YES TECH believed it was possible.

Since there were no comparable products in the market, Wang Chang mentioned that their R&D team couldn’t find ready-made solutions. They had to “feel their way across the river” and make progress step by step.

During a discussion with automotive system engineers, the question arose, “Why not leverage design solutions from the automotive field?” This idea inspired the R&D engineers, and they creatively applied the connection methods used in the automotive field to display screens. The results were astonishing, as the problem of unstable signal transmission was completely solved.

After more than six months of repeated testing, the R&D team continuously adjusted design parameters, simulated customers’ application environments, and finally developed the first-generation product for the magical stage series.

As soon as this series debuted, it won the favor of a large number of customers. It received the “China Innovative Product and Technology Award,” and was included in the “National Torch Plan” and the “Hunan’s Promotion Plan for 100 Key New Products.”

After continuous upgrades, this product series has been selling well for over a decade and is YES TECH’s “flagship product.”

With the expansion of the market and the iteration of products, the research and development work is also endless.

In 2015, YES TECH received a group of Russian customers. It is well known that conventional products are intolerant to extreme temperatures. It was urgent to produce practical products for customers with extreme temperature requirements and upgrade the product performance.

The R&D team conducted numerous basic experiments and adjusted the development structure design of the products based on the analysis of experimental data.

They also changed the product’s heat dissipation methods to meet the application requirements in extreme environments with low and high temperatures.

Wang Chang said, “The tests in extreme temperature application scenarios are much more complex than those in conventional scenarios. You have to consider R&D structure, signal transmission, low and high temperature conditions and various combinations of scenarios. When problems are discovered after the prototype is produced, you have to go back and modify the plans. This process involves a lot of trial and error and can be quite painful.”

However, through continuous efforts, the R&D team overcame one obstacle after another.

These authoritative certifications, like a “National Specialized and Innovative ‘Little Giant” Enterprise,” a “National High-tech Enterprise,” a “National Small and Medium-sized Enterprise for Science and Technology Innovation,” a “National Recommended Enterprise for Key New Products,” a “National Excellent Enterprise in the Electronic Information Industry,” and a “Well-known LED Brand in China”, undoubtedly affirm the strength of YES TECH.

Occupying an important place among more than 2,000 display screen companies worldwide, the company has always attached great importance to the construction of its company culture of “development, expansion, pragmatism, and innovation”, especially “expansion” and “innovation,” which ensure the company’s vitality.

In addition, taking technological innovation, platformization, and intelligent development and design as the core is the driving force behind YES TECH’ continuous innovations.

Since its establishment, YES TECH has collaborated with universities to establish the Hunan Enterprise Technology Center, the Changsha Mini LED Optoelectronic Display Technology Innovation Center and other innovation platforms. 

The number of research and development personnel accounts for nearly 20% of the total number of employees, and the number of R&D engineers with 10 years of experience accounts for over 50% of the R&D team. 

The annual R&D investment accounts for 4%-5% of the total sales, reaching 9.92% during the COVID-19 pandemic in 2020.

As of now, YES TECH has established research and development centers in Changsha and Shenzhen, with 126 proprietary patents, including 3 international PCT patents.

Looking ahead to the future, Wang Chang is full of confidence. He said, “As one of the most popular LED brands globally, YES TECH will continue to expand its presence in the LED display industry, leading the market with outstanding technical strength and a spirit of continuous innovation, and providing customers worldwide with even higher quality products and services.”
