Recently, there has been a significant development in the field of LED displays with the introduction of a domestically produced communication chip.
As widely known in the industry, LED displays, being complex electronic display systems, rely on various types of chips for image presentation, including not just light-emitting chips but also driver chips, control chips, memory chips, and more.
According to Expert Display, a startup company from Shenzhen, DECO INTEGRATION TECHNOLOGY CO., LTD. (hereinafter referred to as “DECO”), has successfully mass-produced a millimeter-wave wireless connection chip. This chip has already been deployed in bulk within the latest products of key customers in the LED display field.

This development marks a crucial step towards the industry’s long-awaited wireless power and data transmission, adding a new class of essential communication chips to the overall LED display solution.
- Millimeter-Wave Wireless Transmission vs. Traditional Solutions
Broadly speaking, millimeter-wave wireless data transmission is an emerging communication technology capable of high-speed, high-capacity data transfers. When applied to the LED display industry, it enables wireless connections between lamp boards and Hub boards, as well as between display cabinets, enhancing LED displays through wireless connections.
Take the example of DECO’s solution for wireless connection between lamp boards and Hub boards. In an LED display cabinet, the control card sends control signals to the lamp boards to manage the brightness, color, and distribution of video content across the LED lights.
Traditionally, this requires numerous cables, floating connectors, or fixed connectors between the cabinet lamp boards and the control card. The number of cables and pins on connectors increases with data transmission and pixel density.
DECO integrates wireless data transmission chips into the Hub boards to directly transmit data to the lamp boards, eliminating the need for cables and connectors between the cabinet lamp boards and the control card, achieving lower latency and higher speeds through wireless transmission.
Beyond the connections within the cabinets, LED display cabinets also typically require Ethernet cables for inter-cabinet connections. DECO’s mmWave wireless data transmission eliminates the need for these cables, further simplifying the installation system of LED displays.
- Significance of “Wireless” in the MLED Trend
This convenience aligns with the development of LED display technology and market demand. Currently, there’s a rising demand for high-definition large screens, and with the rapid development of Mini/Micro LED technology in the supply chain, the pixel density in LED displays is continuously increasing. This means larger, higher-resolution LED displays require more complex wiring and installation, posing challenges in certain market applications and impacting overall display performance.
Under the context of Mini/Micro LED and high-definition display development, the advantages of millimeter-wave wireless connection chips become particularly evident:
Installation Convenience: Wireless transmission eliminates complex wiring, and the small size of the chip saves more space, facilitating the market application of high pixel density Mini/Micro LED products.
High Reliability: Wireless design avoids issues related to line stability, safety, and EMI radiation in complex wiring, reducing design and maintenance costs, and potentially lowering overall costs.
Low Data Latency: With increasing demands for high-definition and low-latency displays, DECO’s chip can achieve stable data transmission at rates up to 18Gbps and latencies below 500ps across various frequency bands.
Enhanced Compatibility: The chip supports multiple protocols, including LVDS, RGB, various communication control signals, and interfaces, providing a highly integrated solution for LED displays.
The introduction of wireless connectivity addresses critical pain points in the rental LED display market, such as the need for quick assembly and disassembly. For outdoor advertising and stage backgrounds, wireless connections also improve aesthetics and safety by avoiding exposed cables, potentially expanding market space.
Moreover, wireless connectivity often aligns with smart technologies, and millimeter-wave wireless connection chips are expected to drive LED displays into more flexible and intelligent markets.
According to Expert Display’s research, DECO plans to continue introducing new products to solve various high-speed, high-frequency, and high-efficiency chip needs for different application scenarios, marking a rapid transition towards wireless LED displays. As the technology matures and market adoption grows, wireless connections are likely to become the mainstream signal transmission method in the LED display industry, fostering continuous development and progress.
- Expert Display Research Conclusion
The application of wireless technology can inspire new design concepts and product forms in LED displays, promoting higher levels of integration and intelligence. The successful development and mass production of this chip indicate its initial market validation and potential for new wireless connection-based models. We look forward to seeing more innovations from DECO’s next-generation wireless products.
