Unilumin and ST develop LED display using 60GHz contactless connectivity chip

STMicroelectronics and Unilumin, a specialist in LED displays based in China, have developed a display using the ST60A2, ST’s 60GHz RF transceiver for advanced high-data-rate contactless-transfer solutions.

These LED displays with the ST60A2 contactless link benefit from the elimination of both cables and connectors and, as a result, are able to chieve significant cost savings by reducing both assembly and maintenance efforts. The contactless approach also enhances system reliability.

The ST60A2 60GHz RF transceiver offers point to point, high-data-rate transmission of up to 6.25 Gbps over distances to a few centimetres. This data link is intended for video display walls and other large-data applications; it also suits industrial markets since the ST60A2 operates over an extended temperature range of -40 to +105°C.

The ST60A2 also offers the flexibility of compatibility with a range of antenna configurations. With a 2.2 x 2.2 mm package footprint, the chip is the smallest device available on the market with ultra-low power consumption of 70mW for a completely contactless link.

“The ST60A2 contactless connectivity technology opens up a new world of innovative products and applications for advanced video solutions,” said Tao Zheng, Director of Unilumin. “Our solution, created with STMicroelectronics, will be applied in new LED-based display products that will be launched throughout 2021.”

“With Unilumin having selected the ST60A2 to improve the reliability of video links inside their equipment, we’ve together affirmed the value of the ultra-high-speed data link and its cost effectiveness and demonstrated the power of this new contactless connectivity technology to optimise existing solutions while creating the potential for new use cases in several areas,” added John Carey, RFC Asia Marketing Director, STMicroelectronics.
