Considerations for video displays
In addition to the normal planning required for all Kalzip FC façade installations, designing for video displays involves special considerations such as pixel pitch, minimum and maximum viewing distances, sampling, and display resolution. From the beginning of dusk until dawn, Kalzip Luminaire systems offer sufficient contrast for the viewing of LED lighting technology. Kalzip Luminaire systems are particular well suited to high resolution video recordings, for external advertising or for the broadcasting of film or TV contents.

Determining pixel pitch and viewing distances for video displays
When using Kalzip Luminaire systems to display video, each node acts as a pixel in the display. Images on an LED video display appear to be sharper to the human eye as the distance to the display increases. Likewise, images appear less visible as the distance decreases. The spacing between pixels, known as the pixel pitch, determines the minimum and maximum viewing distances for discernible video output. Pixel pitch is measured centre-to-centre.

The following calculations and examples are general guidelines for determining minimum and maximum viewing distances, based on video displays using grids of evenly spaced pixels:

•    To determine the recommended minimum viewing distance, multiply pixel pitch by 100 distance units. The standard pixel pitch (node spacing) for Kalzip Luminaire is 100 mm; the minimum viewing distance is 100 x 100 mm = 10 m.

•    To determine the maximum recommended viewing distance for discernible video, multiply the screen height by 20 distance units. For example, if the screen height is 20 m, then the maximum recommended viewing distance for recognizable video is 400 m.

•    LED screens are visible beyond the maximum viewing distance for discernible video. To determine the maximum viewing distance that still creates visual impact, multiply the screen height by 50 units. For example, a screen of 20 m high will continue to create visual impact at 1000 m.

Working with video display resolutions
The pixel resolution of an LED video display equals the total number of vertical and horizontal pixels — the greater the pixel count, the greater the image resolution .

• The resolution of VSE digital video is 1024 x 768
• The resolution of PAL video is 704 x 576
• The resolution of NTSC video is 704 x 480

Kalzip Luminaire system applications
•    Large scale media- and information solutions for shopping centres, sport and leisure facilities, public buildings
•    Public or private buildings with originally and visibility
•    Architectural projects like museums and event buildings, to create a landmark feature

Options

Kalzip Luminaire system (standard)
The standard Luminaire system panels are ready to install and available to meet your immediate needs for large scale video screen applications. The Kalzip Luminaire system in the standard version with 100 mm pixel pitch requires 10 x 10 = 100 LED nodes per square metre. The standard colour is RAL 9006.

Kalzip Luminaire system (exclusive)
With the exclusive Luminaire system almost everything is possible. The material colours and the LED configuration options are nearly infinite, limited only by the imagination. Kalzip Luminaire systems perfectly combine aesthetics and functionality in a unique design configuration.
