Patent number: 8125579Abstract: Provided is a light emitting diode (LED). The LED, in one embodiment, includes a reflective layer located over a substrate and a quarter wave plate emitter layer located over the reflective layer. The quarter wave plate emitter layer, in this embodiment, is substantially crystalline in nature, and further wherein an extra-ordinary axis of the quarter wave plate emitter layer is located in a plane thereof. The LED, in this embodiment, further includes a transmissive/reflective polarization layer located over the quarter wave plate emitter layer, wherein a transmission direction of the transmissive/reflective polarization layer is oriented at about 45 degrees with respect to the extra-ordinary axis.Type: GrantFiled: December 19, 2007Date of Patent: February 28, 2012Assignee: Texas Instruments IncorporatedInventors: Sajjad A.

Patent number: 7993014Abstract: Prism elements having TIR surfaces placed in close proximity to the active area of a SLM device to separate unwanted off-state and/or flat-state light from the projection ON-light bundle. The TIR critical angle of these prisms is selected to affect either the off-state light or additionally, any portion of flat-state light reflected from the SLM. These TIR surfaces limit the contamination of light along the projection path, which tends to degrade the system contrast. To further improve the optical performance of the system, these TIR prisms can be attached directly to the SLM package, completely eliminating the package window.Type: GrantFiled: February 23, 2010Date of Patent: August 9, 2011Assignee: Texas Instruments IncorporatedInventor: Steven M. Penn

Patent number: 7961399Abstract: The addition of DMD illumination modulator(s) 702 in series with projection SLM(s) 706/709 to produce high-performance projection displays with improved optical efficiency, reliability, and lower maintenance requirements. This approach eliminates the vibration, audible noise, and safety problems associated with high speed rotating color filter wheels 203 commonly used in SLM projectors and controls the light applied to individual areas of the projection SLM(s).Type: GrantFiled: July 1, 2008Date of Patent: June 14, 2011Assignee: Texas Instruments IncorporatedInventor: Steven M.

Patent number: 7914151Abstract: In one embodiment, a method includes transmitting one or more light beams by a first portion of a light modulator formed outwardly from a substrate. The one or more transmitted light beams are spatially integrated. A second portion of the light modulator is formed outwardly from the substrate. The second portion of the light modulator spatially integrates the transmitted light beams.Type: GrantFiled: November 30, 2007Date of Patent: March 29, 2011Assignee: Texas Instruments IncorporatedInventors: Andrew Ian Russell, Steven M. Penn, Jeffrey Scott Farris

Patent number: 7817341Abstract: Disclosed is an optical component, which comprises a prism element adjacent to a lens element, where the two elements are separated by a small air gap. In disclosed embodiments, the elements have adjacent and parallel surfaces which are substantially planar and which, with the small air gap, operate through Total Internal Reflection (“TIR”) to direct light beams that strike the planar surfaces. Light beams that strike at less than the critical angle are internally reflected, while light beams which strike at greater than the critical angle pass through. The TIR surfaces thereby separate the desired optical signals from the spurious ones. The combined TIR prism lens operates as a single and integrated component which directs desired light beams to a reflective optical processing element such as a Spatial Light Modulator and which focuses the processed light beams as they leave the combined TIR prism lens.Type: GrantFiled: January 26, 2009Date of Patent: October 19, 2010Assignee: Texas Instruments IncorporatedInventor: Steven M. Penn

Publication number: 20100149626Abstract: Prism elements having TIR surfaces placed in close proximity to the active area of a SLM device 302 to separate unwanted off-state 324 and/or flat-state 326 light from the projection ON-light bundle 322. The TIR critical angle of these prisms is selected to affect either the off-state light or additionally, any portion of flat-state light reflected from the SLM. These TIR surfaces are placed to immediately reflect the unwanted light as it comes off the SLM, thereby preventing the contamination of light along the projection path, which tends to degrade the system contrast. To further improve the optical performance of the system, these TIR prisms can be attached directly to the SLM package 300, completely eliminating the package window.Type: ApplicationFiled: February 23, 2010Publication date: June 17, 2010Applicant: TEXAS INSTRUMENTS INCORPORATEDInventor: Steven M.

To further improve the optical performance of the system, these TIR prisms can be attached directly to the SLM package, completely eliminating the package window. Also, these TIR prism can be coupled to DMDs having asymmetric mirrors, which tilt through a larger angle for the ON-light to provide high etendue and lumen output, but through near-zero degrees for the OFF-light, thereby improving the separation of any unwanted light from the off/flat states.Type: GrantFiled: April 24, 2007Date of Patent: February 23, 2010Assignee: Texas Instruments IncorporatedInventor: Steven M.
