Patent number: 6473149Abstract: An LCD having the liquid crystal in at least a portion of the interpixel region displaced by a spacer material. The spacer material has a low dielectric constant relative to the liquid crystal, thus further impeding the formation of a bend deformation in the liquid crystal in the interpixel region when pixels on opposite sides of the spacer material are operating in the inversion mode. This elimination of the bend deformation in the interpixel region eliminates the reverse tilt disclination.Type: GrantFiled: July 24, 1998Date of Patent: October 29, 2002Assignee: Koninklijke Phillips Electronics N.V.Inventors: George A. Melnik, Robert H. Kane, Ronald D. Pinker, Gerard Cnossen

Publication number: 20020033913Abstract: A projection display device is provided which includes a border structure comprising a dam around the active display area of the device which both shields any underlying drive circuitry from the incidental light by reflecting this light-while passively controlling its birefringence such that this region appears dark to the viewer when no drive voltages are being applied. Preferably, the dam is positioned between the glue seal and the active region, the thickness of the dam being such as to allow a thin layer of LC material on top of the dam for compensated LC effects and in such case, the border structure between the glue seal and the active region is also effective to keep the glue from seeping into the active region when the seal line is squeezed during assembly. With a high birefringence material and an external compensation foil, a high degree of light extinction is achieved over the border. Also, formation of the border on the active plate means that no critical alignment of the passive plate is needed.Type: ApplicationFiled: December 21, 1998Publication date: March 21, 2002Inventors: GEORGE A. MELNICK, RONALD D. PINKER

Patent number: 5965976Abstract: A high pressure gas discharge lamp and the method of making same utilizing integrated circuit fabrication techniques. The lamp is manufactured from heat and pressure resistant planar substrates in which cavities are etched, by integrated circuit manufacturing techniques, so as to provide a cavity forming the gas discharge tube. Electrodes are deposited in the cavity. The cavity is filled with gas discharge materials such as mercury vapor, sodium vapor or metal halide. The substrates are bonded together and channels may be etched in the substrate so as to provide a means for connection to the electrodes.

Patent number: 5811935Abstract: A discharge lamp includes a first and a second substrate (12, 14), a cavity disposed in the first substrate (12) or in a portion of the first and a second substrate (12, 14), a first and a second aligned electrode (270, 272) disposed between the first and a second substrate (12, 14) having respective ends extending into the cavity, wherein the first and the second aligned electrode (270, 272) are "T-shaped" when viewed in cross-section. The T-shaped electrodes provide mechanical support that minimizes bending and distortion in the horizontal and vertical directions. The discharge lamp may include a charge of mercury or an inert gas, and may further include a phosphor layer (80).Type: GrantFiled: November 26, 1996Date of Patent: September 22, 1998Assignee: Philips Electronics North America CorporationInventors: Ronald D.

Patent number: 5213986Abstract: A very thin silicon film SOI device can be made utilizing a bond and etch-back process. In the presently claimed invention, boron dopant is introduced into a surface of a silicon device wafer and the doped surface is bonded onto another silicon wafer at an oxide surface. The device wafer is thinned by etching down to the doped region and, by subsequent annealing in hydrogen, boron is diffused out of the silicon surface layer to produce very thin SOI films.Type: GrantFiled: April 10, 1992Date of Patent: May 25, 1993Assignee: North American Philips CorporationInventors: Ronald D.
