A display system (100) for displaying images from different data streams (1,2) simultaneously is described. Images corresponding to the first data stream (1) are shown to a first observer (106) in a vehicle and images corresponding to the second data stream (2) are shown to a second observer (108) in the vehicle. The display system (100) comprises: a display screen (102) for generating a first one of the images and a second one of the images; and an optical selction screen (104) for selectively passing the first one of the images in a first direction (101) towards the first observer (106) and passing the second one of the images in a second direction (103) towards the second observer (108). It is advantageously that the display screen (102) generates images from both data streams (1,2).
