<p>A flat panel display which allows for precise detection of the location of the cursor with respect to the displayed image. Parallax problems are eliminated by focusing the displayed image on a panel (35) by projection through the panel. The location of a stylus (114) is determined using known digitizing techniques together with the use of an erect, unity magnification imaging lens array (34) for displaying the projected image. Alternatively, the location of the stylus with respect to the displayed image is determined by causing the stylus to feed signals, for example optical signals, through a significant portion of the optical path used for displaying the image.</p> |
