Application cases of ST60 in LED display:
The figure above summarizes some application cases of using ST60 in LED displays, including:
(1) Replacement of connection between module and backplane. The connection between traditional modules and
backplanes
is achieved through B2B connectors, which face reliability problems due to aging and wear during long-term use, and require a large PCB area. Contactless connection can solve complex structural design problems and simplify circuit design.
(2)
Connection replacement between cabinet and
cabinet
. The traditional connection between cabinets is achieved through Ethernet cables, HDMI cables, etc. Using network cables to connect is cumbersome to install and requires high labor and time costs. In addition to effectively reducing the aforementioned costs, non-contact connections can also effectively improve the stability of the connection. Since the ST60 connection occupies a small area and does not require opening holes, this brings the possibility for LED customers to optimize the appearance of their products, such as designing ultra-thin cabinets.
(3) LED 3D holographic display. In the field of LED 3D holographic display, the external circularly polarized antenna of ST60 is used to realize the video connection between the LED rotating fan blades and the main control system at the center, which greatly breaks through the video bandwidth limitation of the traditional connection method, optimizes the video display effect, and reduces the design complexity and connection cost.
