Patent number: 6897855Abstract: A tiled display device is formed from display tiles having picture element (pixel) positions defined up to the edge of the tiles. Each pixel position has an organic light-emitting diode (OLED) active area which occupies approximately 25 percent of the pixel area. Each tile includes a memory which stores display data, and pixel driving circuitry which controls the scanning and illumination of the pixels on the tile. The pixel driving circuitry is located on the back side of the tile and connections to pixel electrodes on the front side of the tile are made by vias which pass through portions of selected ones of the pixel areas which are not occupied by the active pixel material. The tiles are to formed in two parts, an electronics section and a display section. Each of these parts includes connecting pads which cover several pixel positions. Each connecting pad makes an electrical connection to only one row electrode or column electrode.Type: GrantFiled: February 16, 1999Date of Patent: May 24, 2005Assignee: Sarnoff CorporationInventors: Dennis Lee Matthies, Roger Green Stewart, James Harold Atherton, Dennis J.

Patent number: 6624434Abstract: An apparatus for measuring the velocity of a droplet of a liquid includes a laser to generating a beam of light and projecting the beam along a first path. A lens is along the first path for forming the beam into the shape of a thin sheet. A beam divider is along the first path for dividing the beam into two separate beams which extend along second and third paths. The second and third paths lie in a common plane. Along the second and third paths is means for projecting a droplet of liquid across the second and third paths so that the droplet passes through both of the divided beams. AT least one photodetector is along the second and third paths to receive the divided beams and provide an electrical signal corresponding to the beams.Type: GrantFiled: April 20, 2000Date of Patent: September 23, 2003Assignee: Sarnoff CorporationInventors: Zilan Shen, Hyoun Park, Keith Graydon

Patent number: 6476783Abstract: A display device having features which enhance the contrast of displayed images includes a pixel structure that defines an active pixel area and an inactive pixel area. The display device may be an emissive device such as an OLED or electroluminescent device, a transmissive device such as a liquid crystal light-valve device or a reflective device, such as a Bistable, Reflective Cholesteric (BRC) liquid crystal device.

Patent number: 6414661Abstract: A method and associated system that compensates for long-term variations in the light-emitting efficiency of individual organic light emitting diodes (OLEDs) in an OLED display device, calculates and predicts the decay in light output efficiency of each pixel based on the accumulated drive current applied to the pixel and derives a correction coefficient that is applied to the next drive current for each pixel. In one exemplary embodiment of the invention, the calculation is based the accumulated current that has been passed through the device. In another exemplary embodiment, the calculation is based on a difference in voltage across the pixel at two instants. The compensation system is best used after the display device has been calibrated to provide uniform light output.Type: GrantFiled: July 5, 2000Date of Patent: July 2, 2002Assignee: Sarnoff CorporationInventors: Zilan Shen, Dennis Lee Matthies, James H.
