Martin LC/1140 (3.3' x 3.3')
One truly innovative aspect of the LC series is its transparency. With LEDs encased in clear acrylic tubes, the screens are 60% transparent and allow light, air and effects to pass through them.
This opens up a whole new set of possibilities for lighting and stage designers.
Dim the panels and they seem to ‘disappear’, revealing objects or performers placed upstage. Light can be projected from behind and smoke effects made to emerge through the screens. In architectural applications video walls can be placed behind windows to allow sunlight into interior spaces.
The LC is an extremely bright video source. With an output of 1800 NITs (cd/m2), the LC is clearly visible in daylight, making it suitable for large-scale and outdoor productions.
With a 40 mm pixel pitch, the LC offers excellent resolution without compromising on its light weight and transparency. A video wall’s resolution is determined by its pixel pitch. High resolution screens have a fine pixel pitch: typically around 6 mm. Low resolution screens can go up to 100mm. The LC has an ideal balance at 40mm, which means it remains lightweight, transparent and relatively inexpensive but is still tight enough to offer excellent image quality.
The LC portrays seamless images at thirty meters and beyond. Although still a useful effect at shorter distances, a simple rule of thumb is that in order to see an unpixelated image on an LED video screen, you need to be at a viewing distance of 750 times the pixel pitch. LC panels present a seamless image at about 30m (750 x 40mm = 30m) or 100 ft.
Wide viewing angle
Another important feature of the LC has to do with the pixel design. While most LED screens use triangular configurations, the LC comes with elliptical pixels. This offers a very wide, 100° viewing angle, a feature that is especially valuable for applications where you can cover not only the front but also the sides where people tend to miss out.
The LC’s Genlock feature makes it ideal for TV and video applications. A DVI buffer box is available for the panels as a separate item.
LC units are built tough for the road and smart for easy set-up. With no external drive or power boxes, each unit comes with everything built in - substantially reducing the weight and costs of shipping as well as the set-up time.
Simple mounting system
You can easily stack or hang the LC Series. With standard Prolyte CCS6 conical truss connectors, connecting the lightweight units together is simple and the resulting structure is very sturdy.
Data and power can be daisy chained between frames with standard DVI and PowerCon cables so you don’t have to run a separate cable to each frame from a control box. A maximum of five LC 2140 panels or ten LC 1140 panels may be connected together at 230 V, and up to 6 frames via standard DVI-D cables on one link.
Each unit contains a switch mode power supply that covers all worldwide voltages, so you are always ready to go - anywhere in the world.
The lightweight units can be packed four frames to a flight case, which means fewer flight cases and a reduction in shipping cost.
