  • Low Resolution LED Video
    Also known as "Low Res". This is where the distance between pixels is deliberately much bigger than the diameter of the pixel itself. The space between pixels becomes part of the effect.

    There are many reasons why a designer might find this desirable.
     
    One reason would be that the space between pixels can be transparent. This transparency could let light through either way to allow “reveals” behind the screen or allowing back lighting through the screen. With good “open air” transparency, the screen would also allow wind, smoke and sound to pass through. G-LEC transparent screens have been used to mask huge speaker stacks for rock concerts and also used in very windy outdoor positions.

    Another reason would be to add “pixel sparkle” to the lighting effect. Often used in television game shows and award ceremonies, as the television camera lens just loves the color and granularity, adding to the feeling of depth of field and excitement. This “pixel sparkle” is also used to great effect by car manufacturers, as the bright LEDs reflect off the highly polished cars at motor shows, adding texture and “psssing!”

    Of course, we also have the very large screen that is viewed from a distance. G-LEC has provided screens that have been hung on buildings façades. Not only would it be prohibitively expensive to use a High Res screen, but the weight of such a beast would require some complex and expensive reinforcements of the building. And, not forgetting the people inside, they can also still see daylight!

    There are as many reasons to use Low Res screens as there are imaginative Designers and Producers. How would you use one?
