A kind of display with interesting new applications for indirect viewing is discussed in more detail. This line-display is especially suitable for indirect viewing with a very wide horizontal field of view, e.g. as needed for driving vehicles in darkness and bad atmospheric conditions, when used with appropriate video-sensors. The basic idea about the line-display is to divide a display into two components, a physical horizontal single light-emitting line, which then is scanned vertically into a virtual image. The line-display then makes it possible to install large, panoramic screens in confined spaces. Self-motion in the surrounding real 3D-world generates motion parallax, except from a zone straight ahead. Using motion parallax for good perception requires a large horizontal field of view. A small magnification or demagnification in a scene from indirect viewing, results in a quite dramatic change in perception. Scaling between the real world scene and the perceived display image should therefore be 1:1 to preserve correct angular speed for objects in the scene. In addition, the larger the viewing distance to the display is, the less visual conflicts will arise, e.g. from convergence versus accommodation.
