    摘要: A projection system including a light source, a color separator, a scrolling unit, a light valve, a wire grid polarization beam splitter, and a projection lens unit is provided. The color separator separates an incident beam according to color. The scrolling unit scrolls the color beams. The light valve processes an incident beam according to an image signal and forms a color picture. The wire grid polarization beam splitter is disposed between the scrolling unit and the light valve and transmits or reflects an incident beam according to a polarization of the incident beam. The projection lens unit magnifies the color picture formed by the light valve and reflected by the wire grid beam splitter and projects the magnified color picture onto a screen.

    摘要: A spiral lens disk and a projection system adopting the same are provided. The spiral lens disk has spirally arranged cylinder lens cells and scrolls incident light by converting the rotation of the cylinder lens cells into rectilinear motion of a cylinder lens array. The projection system includes at least one spiral lens disk such that color scrolling is achieved using a single component to form a color image. Due to a reduction in the number of components, a light, low-price projection system can be obtained, and a single-panel projection system with high light efficiency can also be obtained.
