LEDVideowand

LEDVideowand is a large display comprised of multiple LED panels arranged to form a seamless visual surface. It is used to present video, graphics, and other content in venues such as arenas, broadcasting studios, retail spaces, and event venues. Each panel contains a light-emitting diode array and is equipped with the electronics for driving the LEDs, power, and data interfaces. Panels are mounted in cabinets or modules and connected to a frame or wall. Pixel pitch, the distance between neighboring LEDs, determines resolution and viewing distance; indoor pitches commonly range from about 1.2 to 6 mm, while outdoor walls use 6 to 20 mm or more. Brightness and contrast are higher for outdoor units to counter ambient light, with typical values in the thousands of nits.

Content is managed by a video processor or image controller and distributed across panels via sending and receiving cards. Calibration and color matching are performed to ensure uniform brightness and color across the wall. The result is a large, scalable display that can be configured to various aspect ratios and shapes, including curved surfaces.

Applications include live events, sports venues, broadcast studios, control rooms, retail signage, and corporate lobbies. Advantages of LEDVideowand include modularity, scalability, high brightness and contrast, durable construction, and simple replacement of individual panels. Limitations include a higher upfront cost, installation and calibration complexity, and ongoing maintenance requirements. Compared with projection, LEDVideowand offers better ambient light performance, wider viewing angles, and longer life, at the expense of higher total cost and power use.
