I've been asked to find an outdoors LED display panel for a small local football team / sports arena. They primarily want it to display a static picture (their logo), but would want the ability to easily change the picture or if necessary add small animations (possible advertising).
Finding a panel is easy, I figure it should be 128x128 "pixels/LEDs" and RGB in order to display their logo, a quick search gives a good candidate for the hardware I'm looking for:
http://www.alibaba.com/product-detail/5000nits-outdoor-stage-P5-die-casting_60083297683.html -- but there is little to no information on how these panels are operated and programmed in practice. And we all know how the 'Chinese' can be on software..

This panel will be controlled by non-technical people (with my written instructions), so it must
easy to use. I can create the necessary content, however.
It must have an accessible interface (like USB) that connects to a PC or has removable storage. It must ideally be able to load a regular image file (bitmap, jpeg) that is converts to a display (I can make this image file to the necessary format and size).
For animations, maybe it can load an animated GIF? Either that or a sequence of image files that plays a given duration set by a GUI (?).
Anyone know manufacturers that makes panels of this "ease of use"? Any help here would be very much appreciated.
