  • Patent number: 4729165
    Abstract: A method for producing adhesive contacting of an IC on a substrate of a LC cell, comprising suspending the leads of the IC, in the opening of an insulating frame by means of the leads surrounding the leads with conductive adhesive and adhesively securing them on the substrate by means of the frame.
    Type: Grant

  • Patent number: 4548475
    Abstract: A liquid crystal display device comprises a plurality of electrically controllable active regions filled with liquid crystal and defined by a plurality of dams, and a plurality of empty passive regions also defined by the dams. An outer peripheral seal completes the closure of the active or passive regions and top and bottom cover plates are provided above and below the regions. The empty passive regions may be partially evacuated to increase the mechanical connection between the cover plates and the active regions may be connected by passages also defined by the dams so that a single filling port can be utilized to fill all of the active regions of liquid crystal.

  • Patent number: 4255806
    Abstract: A display for an electronic timepiece or the like has an analog electro-optical display comprising a plurality of segment electrodes radially disposed about a center point and at least one first counterelectrode each bridging at least two radial segment electrodes and a digital electro-optical display comprising a plurality of digital electrodes which define at least one alphanumeric character and at least one second counterelectrode. By using at least two first counterelectrodes each having a different set of radial segment electrodes associated therewith and electrically connecting at least one radial segment electrode of one set in parallel with one radial segment electrode of the other set and in parallel with one digit electrode, the display may be driven in a time multiplex manner with a minimum number of external display connections.

  • Patent number: 4242747
    Abstract: A chronometric indicator for a watch has concentric arrays of angularly equispaced electrodes and analog display segments. The electrodes are staggered relative to the display segments so that each electrode overlaps halves of two adjacent segments, so that by selective energization of the electrode and the segments any half can be optically activated. In addition a digital display is provided within the two annular arrays, with each digit segment of the display being connected to a respective analog segment. A common connection for this digital display can be energized simultaneously with any of the outer analog segments to cause the corresponding digit segment to glow. The overlapping arrays of electrodes and analog display segments are energized to indicate the hour and minute, and the digital display is energized to indicate the second.

  • Patent number: 4198810
    Abstract: A chronometric indicator has a multidigit display each of whose digits is formed by a plurality of individually energizable digit segments having respective digit-segment connections and having a common digit-display connection so that simultaneous energization of the common connection with any of the digit-segment connections will optically activiate the respective digit segments. An annular array of sixty angularly equispaced analog display segments surrounds the multidigit display and has an analog-segment connection for each part and inner and outer rings subdividing the analog display segments into inner and outer parts. Simultaneous energization of the inner or outer rings and one of the analog-segment connections will optically activate the corresponding inner or outer part. Each of the digit-display connections is connected to a respective one of the analog display segments.
