If you are looking for a display on the go this new Kickstarter will be of interest to you. It is an interesting collapsible display that uses a short through high power DLP projector to get the job done. It has already tipped so this will become reality. Until a paper think color roll up display is available this will be the next best thing.
“SPUD is the only high resolution, 24-inch display with the awesome benefit of ultra-portability. It collapses just like a ruggedized umbrella to the size and weight of a paperback book – making it ideal for anyone on the go.
When expanded, SPUD uses custom optics combined with the latest DLP technology to produce the sharp, bright image that you need. Either with an HDMI cable or wireless adapter, SPUD can be connected to a smartphone, tablet, or laptop – no matter where you are!”
