  • Liquid crystal display device achieving imaging with high S/N ratio using invisible light
    Patent number: 7701448
    Abstract: A liquid crystal panel brightness controller notifies a backlight controller that an illuminance of ambient light is equal to or less than a threshold value. Upon notification, the backlight controller causes invisible light emitted, for example. The invisible light passes through a liquid crystal panel and is reflected by an imaging target and is received by photosensors. Accordingly, the decrease in the amount of the visible light received by photosensors is compensated. As a result, an image with a high S/N ratio is obtained.

  • MOTION ARTIFACT MEASUREMENT FOR DISPLAY DEVICES
    Publication number: 20100066850
    Abstract: A video signal generator provides a test pattern to a display device for measuring a motion artifact (e.g., moving-edge blur) of the display device. The test pattern includes a moving image and a shift velocity of a time-delay integration (TDI) camera is matched to the velocity of the moving image to track a moving edge of the image. The captured image is analyzed to determine a characteristic indicative of the motion artifact of the display device (e.g., the blur edge time).

  • Board device and method for manufacturing display element
    Patent number: 7675602
    Abstract: A pillar-shaped spacer is disposed at the position between the boundary line of adjacent liquid crystal cells and an OLB terminal so as to face the end portion of the OLB terminal and so as to be interposed between a first large-size substrate and a second large-size substrate. Even when the respective liquid crystal cells are separated from one another along the boundary lines of the adjacent liquid crystal cells, exfoliation of the OLB terminals is prevented by the pillar-shaped spacers, so that extra cutting margins between the adjacent liquid crystal cells can be reduced and the manufacturing performance and the built-in number of the liquid crystal cells can be enhanced.

The invention also relates to molecular device substrates fabricated by and/or use in such methods. We describe an optical or optoelectronic device comprising a substrate and a plurality of discrete bank structures disposed on the substrate, wherein: each bank structure defines the perimeter of at least one well; one or more of a charge transporting, charge injecting, light-filtering and light-emitting material is disposed in the well; and at least one bank structure defines the perimeter of at least one well and does not extend to the perimeter of any adjacent well. Thus in embodiments no part of said perimeter defines the bank of more than one well.
