In this paper we present a multi-view stereo display concept based on pulsed LED light sources of a 3 LED/3 LCD projector. Switching LED sources allows high frequency shuttering of the displayed image and can therefore be used for multi-view systems. We have implemented a two user system which can be extended to more views with little expenditure. This alleviates the known principal problems of shutter-based multi-view systems of energy inefficiency, brightness degradation due to the projector shutter, and increasing crosstalk with the number of views.
