Patent ID: 8300159

Claim:
A pico projector, comprising a light-emitting diode module, collimators, a lens array, magnification lenses, a reflection mirror, a polarizing beam splitter, an LCoS panel, and an image lens module, characterized in that: 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 component of the light and reflects a vertical polarization component of the light; the LCoS panel reflects and modulates the light to form an optic signal to be projected to a screen; and the image lens module comprises an assembly of lenses including sequentially positive, positive, negative, positive, and positive lenses to project an image from the LCoS panel to the screen.
