  • Patent number: 7864136
    Abstract: A tiled display device is formed from display tiles having picture element (pixel) positions defined up to the edge of the tiles. 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 tiles are 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. The connecting pads on the display section are electrically connected and physically joined to corresponding connecting pads on the electronics section to form a complete tile.

  • Patent number: 7192793
    Abstract: An organic light emitting device display may include transverse row and column lines. In a passively driven OLED display, a fuse may be positioned between the OLED material and the row electrode. When a short occurs, the single pixel may be separated from the circuit by the fuse, avoiding the possibility that an entire row of pixels may be adversely affected by the short associated with one single pixel along a row.

  • Patent number: 6897855
    Abstract: 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.

  • Patent number: 6624434
    Abstract: 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.

  • Patent number: 6476783
    Abstract: 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. The ratio of the active pixel area to the total pixel area is less than 50 percent. The display device includes a transparent cover plate having a black matrix formed on the viewer side of the cover plate. The display device may be a tiled display in which case the black matrix is formed on an integrator plate to which the individual tiles are bound to form the complete display device. For reflective or emissive display materials, the display device includes an electronics section including a circuit board which provides driving signals for the pixels of the display device.

  • Patent number: 6414661
    Abstract: 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.
