  • Illuminated liquid/crystal display device using internal reflection and scattering
    Patent number: 4626074
    Abstract: A relatively shallow arrangement for providing illumination for a light scattering type display cell employs a transparent sheet in optical contact with the front surface of the cell and a matte black sheet out of contact with the rear surface. The assembly acts as a light guide for light launched into at least one of the transparent sheet from at least one strip lamp. The only light escaping from the display, etc. in the direction of the observer is a proportion of that scattered into non-guided directions by regions of liquid crystal layer selectively set into a scattering state.
