Patent number: 6816225Abstract: A display device and method for fabricating a liquid crystal cell are disclosed. A liquid crystal cell includes a first substrate, and a second substrate attached to the first substrate. The first substrate has a same thickness as the second substrate. The first substrate is lapped at a first rate while concurrently lapping the second substrate at a second rate, which is different from the first rate. The first substrate and the second substrate are thinned to different thicknesses. The thinner of the first and second substrates is provided on a viewer side of a collimate and post diffuse type liquid crystal cell to reduce depixelization.Type: GrantFiled: June 26, 2001Date of Patent: November 9, 2004Assignee: International Business Machines CorporationInventors: Evan George Colgan, Fuad Elias Doany, Tomohito Jounai, Satoshi Maruyama, Hideo Ohkuma, Rama Nand Singh, Masaru Suzuki

Patent number: 6791639Abstract: In a liquid crystal display device of a direct view type, a lenticular lens sheet is provided in the backside of a liquid crystal display panel. Light emitted to a lens of the lenticular lens sheet is first converged in the liquid crystal display panel, and then diffused. When the light is emitted from the liquid crystal display panel, the radiation distribution thereof is widened. Thus, a bright display screen even when seen from a wide angle can be realized.Type: GrantFiled: May 14, 2002Date of Patent: September 14, 2004Assignee: International Business Machines CorporationInventors: Evan George Colgan, Fuad Elias Doany, Rama Nand Singh, Masaru Suzuki

Publication number: 20040114859Abstract: Optical devices, components and methods for mounting optical fibers and for side-coupling light to/from optical fibers using a modified silicon V-groove, or silicon V-groove array, wherein V-grooves, which are designed for precisely aligning/spacing optical fibers, are “recessed” below the surface of the silicon. Optical fibers can be recessed below the surface of the silicon substrate such that a precisely controlled portion of the cladding layer extending above the silicon surface can be removed (lapped). With the cladding layer removed, the separation between the fiber core(s) and optoelectronic device(s) can be reduced resulting in improved optical coupling when the optical fiber silicon array is connected to, e.g., a VCSEL array.Type: ApplicationFiled: December 17, 2002Publication date: June 17, 2004Applicant: International Business Machines CorporationInventors: Evan George Colgan, Fuad Elias Doany, Bruce Kenneth Furman, Daniel J.

Patent number: 6707444Abstract: Projector and camera arrangements are provided for use in electronic whiteboard systems. Specifically, the present invention provides projector and camera arrangements wherein the projector and camera share the same imaging optics. By sharing the same projection and camera optics, the distortions that affect the projection system are the same as those of the camera system. Thus, the calibration step required in conventional whiteboard systems where the projector and camera are separate, i.e., each having their own distinct optics and settings, is no longer needed. Further, the arrangements provided in accordance with the invention are self-aligning, even when lens distortions are large and even in the presence of strong perspective effects. The shared optics projector and camera arrangements of the invention also provide for dynamic zooming. In addition, various active and passive optical marker or lightpen designs are provided for use in electronic whiteboard systems.Type: GrantFiled: August 18, 2000Date of Patent: March 16, 2004Assignee: International Business Machines CorporationInventors: Ferdinand Hendriks, Fuad Elias Doany, Zon-Yin Shae, Belle L.

Publication number: 20030165013Abstract: An illumination system and display are disclosed that include a light for providing light, a polarizing beam splitter (PBS) having a first surface that receives the light from the backlight. The PBS passes a first polarization of the received light to a curved mirror located at a second PBS face, which second PBS face is opposite the first PBS face. The curvature of the mirror provides the optical power necessary for proper imaging, while limiting the reflecting area of the mirror provides an aperture stop that determines the numerical aperture of the optical system. The display also includes a quarter wave plate and a spatial light modulator (SLM). The quarter wave plate is located between the PBS and mirror and changes the first polarization of light, directed from the PBS to the mirror, to a second polarization which is reflected from the mirror back to the PBS.Type: ApplicationFiled: March 11, 2003Publication date: September 4, 2003Applicant: International Business Machines CorporationInventors: Fuad Elias Doany, Rama Nand Singh

Patent number: 6247816Abstract: An optical system for a projection display employing three reflective spatial light modulations (SLM's) is described. Two or the three SLM imaging paths employ typical image combining and projection optical techniques. However, the third SLM imaging path employs a relay lens to produce an intermediate image of the SLM which is subsequently combined with the other two images. Each color component is directed onto one of three SLM's, each through its own polarizing beamsplitter (PBS) cube. In two of the three SLM's, image forming light is reflected from each SLM and passes through its respective PBS, and the two colors are then recombined using a dichroic coating. A lens then images the two-color image, and projects it onto a screens. The third SLM traverses a completely separate path. In this case, the image forming light reflected by the SLM and passing through the PBS is first imaged by a relay lens of approximately unity magnification to produce an intermediate image plane.Type: GrantFiled: August 7, 1997Date of Patent: June 19, 2001Assignee: International Business Machines CorporationInventors: Thomas Mario Cipolla, Fuad Elias Doany, Robert Lee Melcher, Rama Nand Singh

Patent number: 6219183Abstract: A rear projection display is disclosed having a projection device, a screen, and a screen moving device. The projection devise projects an image, the screen is provided for displaying the image, and the screen moving device is used to move the screen in relation to the projection device. The screen moving device has a first frame attached to the screen that telescopically move over a second frame to extend and retract the screen. In the retracted position, the screen is flush with a display box that contains the projection device. As the screen moves away from the projection device, the image increases in size. The projection device includes a projection lens which may be a fixed focal length lens. Two folding mirrors of the projection device provide a folded projection path to reduce a dimension of the display. The screen moving device has an opening to move the screen toward the projection device without interfering therewith. A flexible light blocking material covers the opening.Type: GrantFiled: April 21, 1997Date of Patent: April 17, 2001Assignee: International Business Machines CorporationInventor: Fuad Elias Doany
