  • Patent number: 8300159
    Abstract: A pico projector includes a light-emitting diode module, collimators, a lens array, magnification lenses, a reflection mirror, a polarizing beam splitter, an LCoS (light crystal on silicon) panel, and an image lens module, wherein the light-emitting diode module emits red, green, and blue lights. The collimators convert light from the light-emitting diode module into collimated light. The lens array homogenizes the collimated light. The magnification lenses magnify the homogenized light from the lens array with a predetermined ratio to be projected onto the LCoS panel. The reflection mirror changes direction of the light path. The polarizing beam splitter allows for transmission of a horizontal polarization light component and reflects a vertical polarization light component. The LCoS panel reflects and modulates the light to form an optic signal. The image lens module includes, in sequence, positive, positive, negative, positive, and positive lenses to project the optical signal to a screen.
