20110164227	Optical system for a digital light projection system including a multi-light path lens - An optical system for a digital light projection system is provided. The optical system comprises an illumination source that generates unmodulated light. The optical system also comprises a multi-light path lens that receives the unmodulated light, wherein the multi-light path lens includes at least one reflective surface that reflects the unmodulated light. The optical system further comprises a modulator that receives the reflected unmodulated light, whereby the modulator generates modulated light. The multi-light path lens receives the modulated light. The multi-light path lens is used within both the unmodulated light path and the modulated light path. In other words, the multi-light path lens is used within both the illumination optical path and the imaging optical path to thereby provide an extremely compact optical system.	07-07-2011

20130188156	OPTICAL SYSTEM FOR PROJECTION DISPLAY APPARATUS - This invention concerns an optical system for a projection display device that includes: a first lens which may emit light entering from a light source with a same angle to a single point; a second lens which is positioned in a way that the light collected from the first lens may be transmitted to a digital micromirror device (DMD) with a predetermined angle; a DMD which may reflect the light entering from the second lens; a prism positioned between the second lens and the DMD that transmits and transfers the light emitted from the second lens to the DMD, and transfers the light reflected from the DMD to a projection lens by totally reflecting the light; and a projection lens that is positioned in the optical path of the light totally reflected from the prism, to project the light onto a screen. According to this invention, as described above, by providing an optical system for a projection display apparatus that is asymmetrically positioned by implementing a symmetric lens that compensates for the optical path difference of light incident on a DMD from a light source, the manufacturing of the system becomes easy. In particular, the use of the symmetric lens makes the lens processing and tolerance management easier at a lower price during the lens production compared to the conventional asymmetric lens. Also, it is easy to set the placement between the symmetric lens and the prism.	07-25-2013
