ABSTRACT:
A lenticular screen display designed for viewing in sunlight which comprises an array of parallel, horizontally arranged cylindrical lenticules with a sequence of animated images on a section located in the top portion of the focal plane of the lenticules, and means for preventing the sun's rays from focusing on the focal plane of the lenticules so as to prevent burning the image bearing sections. The means for preventing the sun's rays from focusing on the image bearing section can be diffusers or reflectors located in the lenticule at the appropriate position. Another means is to alter the focal length of the lower portion of the lenticules so it is either less or greater than the focal length of the top portion. A further means is to make the top portion of the front surface of the lenticule flat.
