摘要： A display system includes respective light sources disposed at two opposed light input ends of a light guiding plate. A double-sided prism sheet is disposed on a light-emitting side of the light guiding plate and includes, on a first surface facing the light guiding plate, a triangular prism bank extending in a direction parallel to the light input ends of the light guiding plate. The double-sided prism sheet includes, on a second surface, opposite to the first surface, a cylindrical lens bank extending in a direction parallel to the triangular prism bank. A transmissive display panel is disposed on a light-emitting side of the double-sided prism sheet. A synchronization driving section alternatively illuminates the respective light sources so the transmissive display panel displays two different images. The light from the light sources is emitted through the transmissive display panel at respective divergent angles producing two images corresponding to right and left parallax images, producing a stereoscopic display.
