20110261274 | STRUCTURE OF PICO PROJECTOR - 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. | 10-27-2011 |
20110317134 | MODULAR STRUCTURE OF PICO PROJECTOR - The structure of a projector contains a light path module, a projection lens module, a source lens module, a reflection mirror module, a reflection panel module, and a light source module. The light path module has a U-shaped body. The source lens module and the light source module are configured along a left side of the light path module. The projection lens module is configured along a right side of the light path module. The projection lens module is for projecting image to a screen. The source lens module is for modulating the light from the light source module. The reflection mirror module is installed at a left corner of the light path module to reflect the incident light from the light source module towards the reflection panel module. The reflection panel module is installed from the outside of a right corner of the light path module. | 12-29-2011 |
20120002171 | PROJECTION LENS MODULE OF PICO PROJECTOR - The projection lens module contains a number of lenses, a stop, a PBS (polarizing beam splitter), and a LCoS (liquid crystal on silicon) panel. The lenses, from outside towards inside, contains a negative first lens, a positive second lens attached to the negative first lens, a negative third lens, a positive fourth lens forming a doublet structure with the negative third lens, and a positive fifth lens. The stop is positioned between the positive second lens and the negative third lens. The PBS is positioned between the positive fifth lens and the LCoS panel, and the positive fifth lens has an area larger than that of the LCoS panel. The LCoS panel is positioned behind the PBS. The projection module is able to overcome the size issue of the projection lens module, to enhance image resolution and to reduce image distortion. | 01-05-2012 |
20120002174 | LIGHT SOURCE SYSTEM OF PICO PROJECTOR - The a light source system of pico projector is composed of a light-emitting diode module, collimators, a lens array, magnification lenses, and an LCoS (light crystal on silicon) panel, arranged in sequence with appropriate spacing in-between. The light-emitting diode module, as the light source, 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 onto the LCoS panel. The LCoS panel reflects and modulates the light to form an optic signal to be projected to a screen. | 01-05-2012 |
20120069251 | DUAL PANEL MICRO REFLECTIVE LIQUID CRYSTAL PROJECTION DEVICE - A dual-panel micro reflective liquid crystal projection device is provided for improving brightness of projected image, including a set of two reflective liquid crystal panels respectively arranged at top side and right side of a polarizing beam splitter so that a light beam emitting from a light source located at bottom side of the beam splitter is received and split by the beam splitter into a horizontal polarization component and a vertical polarization component, which are then respectively reflected and modulated by the two reflective panels into vertically polarized light and horizontal polarized light for simultaneously transmitting identical image signals to a projection system arranged at left side of the beam splitter to thereby double the brightness of the image projected onto a screen. | 03-22-2012 |
