摘要： A cylindrical lens array for achieving color scrolling, a projection system using the cylindrical lens array, and a scrolling method. The cylindrical lens array is formed by arranging lens cells in an endless track. When the cylindrical lens array rotates, light rays passing through the lens cells advance along different paths. The projection system includes a light source, the cylindrical lens array, a light splitter, a light valve, and a projection unit. The light source emits a light. The cylindrical lens array has a plurality of lens cells arranged in an endless track and scrolls color bar images upon rotation. The light splitter splits incident light emitted from the light source into color beams according to a wavelength. The light valve receives the color beams split by the light splitter and scrolled by the cylindrical lens array and forms a color image by turning pixels on or off according to an input image signal. The projection lens unit magnifies the color image formed on the light valve and projects the magnified image onto a screen.
