Filed:

Dec 1, 2000

Appl. No.:

09/728522

Inventors:

Christopher L. Bohler - Allen TX
Frank J. Poradish - Plano TX
Claude E. Tew - Dallas TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

F21V 900

US Classification:

362293, 362268, 362242, 362228

Abstract:

In an SLM-type display system, a solid state light source can be used to augment a lamp light source in a least two different ways. First, a solid state source can be used to augment deficiencies in a particular spectral region. Typically, lamps are deficient in red, and a red solid state source would be used. However, the same concept applies to augmenting any color region. Multiple solid state sources could be used to augment more than one region. Second, when the SLM system uses a color wheel, a solid state source can be used to eliminate âspoke lossâ. Multiple solid state sources can be used for providing different colors during the spokes.

US Classification:

430 5, 430 22, 430321

Abstract:

An improved reticle ( ) and method of using it to expose layers of wafers for large integrated circuits ( ). The integrated circuit ( ) is designed so that nonrepeating patterns are laid out in perimeter areas, distinct from the center area containing contiguous repeating patterns. The reticle ( ) is patterned with multiple masks ( ), with different masks representing the repeating and nonrepeating patterns. The mask ( ) representing the repeating pattern may then be stepped and illuminated separately from any mask ( ) representing a nonrepeating pattern.

International Classification:

G02B 2714

US Classification:

359634, 359638, 353 33

Abstract:

Methods for measuring and automatically controlling the light distribution and overall brightness in electronic-based spatial light modulator projection display systems. One method takes a small fraction of the projected light from a partial turning mirror in the projectors optics path and focuses this light on to a detector for use in controlling the light distribution and brightness of the system. Another method uses an array of embedded light sensors at chosen locations on the surface of a display screen to control the light distribution and brightness parameters of the projection system. Both methods use a micro-controller, servomotors, and an adjustable power supply, controlled by the detector/sensor outputs, to maintain the desired light distribution and brightness in the projected image.

Abstract:

A three element prism system and method for splitting/combining three different colors of light arranged such that the size of a selected one of the color prism, such as for example, the red prism and, consequently the clear aperture, are increased without a corresponding increase in the size of the other prisms (e. g. , the blue and green prisms). This is accomplished by adjusting the air gap Aof the selected light path (e. g. , red) so that the effective total selected light path T, which includes the selected light air gap Aand the selected light glass path Gis the same as the total path length T of both the other light paths (e. g. , green and blue) comprised of air gap Aplus glass path G.

US Classification:

359292, 345 85

Abstract:

An optical system for projecting an image having x and y axes onto a image plane is provided. The system includes an SLM device spaced from the image plane, the SLM device having a plurality of pixels operable to project pixels of the image onto the image plane and positioned such that the individual pixels of the projected image are oriented at substantially 45 degrees relative to the x and y axes of the image. The system further includes an optic element disposed between the SLM device and the image plane and a linear displacement device operatively connected to and operable to selectively displace at least one of the SLM device and the optic element. A method for projecting an image onto a image plane is also provided.

US Classification:

362294, 362345, 362373

Abstract:

To improve the cooling efficiency and ensure uniform cooling of all portions of the inside back surface of the reflector, a deflector () has been developed. The air deflector () typically encircles the lamp () allowing air () to flow between the deflector () and the lamp (). This air () cools the lamp (). Air () passing between the deflector () and the reflector () is deflected outward to cool the inside surface of the reflector near the lamp (). Because the deflector () is small and is located directly behind the lamp (), it does not block any of the useful light generated by the lamp (). The light striking the deflector () from the lamp (), if not for the deflector (), would have passed through the opening in the reflector () and would have been lost. The deflector () typically has a number of vanes around the perimeter of a cylindrical body portion. The vanes are bent outward at an angle sufficient to force part of the cooling air to flow across the inside back surface of the reflector.

Abstract:

System and method for synchronizing shutter glasses with a display system. An embodiment comprises displaying a first image from a first image stream on a display plane, displaying a second image from a second image stream on the display plane, and displaying a synchronization signal on the display plane, during a first, a second, and a third display period, respectively. The first image and the second image are displayed at least partially on the same area of the display plane and the first and the second display periods do not overlap. The display of the synchronization signal on the display plane enables the elimination of a dedicated synchronization signal broadcast unit, thereby reducing the cost while increasing the reliability of a display system.
