Abstract
A screen has first and second sides to receive at least one beam on the first side and to display an image on the second side opposite the first side. The beam represents the image. The first side includes a collimating structure to direct the beam from the first side through first striped regions of the screen to the second side. The screen includes second striped regions, positioned between the first and second sides, to emit near-IR light to the second side in response to an excitation source that is selected from a group consisting of an electrical excitation source and a photoluminescence excitation source. The second side includes a diffusion layer. The first side is viewable to detect a portion of the emitted near-IR light reflected back from the second side through the first striped regions to the first side. The detected portion is processable to determine a position touch on the second side.
