摘要： The molecules in a twisted nematic liquid crystal are, in general, skewed relative to the optical axis of the cell (the perpendicular to the plane surfaces defining the boundaries of the crystal cell), and their birefringent effect on plane polarized light varies asymmetrically for such light making varying angles with the optical axis of the cell. When the cell is positioned between crossed polarizers and the cell is energized so that light is supposed to be completely extinguished, some rays are nevertheless transmitted so that the transmitted intensities at different viewing angles vary. To avoid this resulting variation of intensity with viewing angle, the cell is illuminated from behind with collimated light (i.e., all rays parallel to the optical axis of the cell) so that all rays "see" the average molecular director in the same way; a solid catadroptric element is utilized to both collimate the light and achieve essentially constant luminous flux intensity upon the display. To restore a reasonably wide angle of view, a diffuser is positioned in front of the display. The invention may be used with any type of display device which has a transmission characteristic which varies with the angle of rays passing therethrough.

摘要： A printer head for use in an impact printer of the dotmatrix type utilizes a stack of pivoted thin blades, each having a printing tip at one end thereof. A pancake coil is attached to each blade for initiating selective independent movement thereof within a common, externally-produced magnetic field to efficiently convert electrical print signals to kinetic energy in each printing tip of a vertical array thereof thereby facilitating printing of symbols, characters and other indicia on underlying media with high resolution. The single magnetic-field-producing means interacts with all pancake coils of the stack of printer blades to facilitate close spacing of the printing tips for superior character printing. Resilient members are integrally formed in each blade to support the moving structure with negligible loss, thereby increasing the printing speed of the stacked blade head.

摘要： Methods for matrix addressing a liquid crystal display, utilizing the cholesteric-to-nematic phase change for information display, provides a voltage to each of a plurality of scanned electrodes. A preferred voltage waveform has a first non-zero value during an erase interval and a greater non-zero value during a display-write interval. The combined erase and write intervals occur, for each scanned electrode, once during a multiplex time interval. Each of another plurality of electrodes, arranged adjacent to the remaining surface of a liquid crystal layer and perpendicular to the scanned electrodes, are sequentially energized with a non-zero voltage having a polarity change coincident with the erase and write intervals when that portion of a display at the intersection of the first and second plurality of electrodes is to be addressed. If the inverted-polarity voltage is in phase with the scan electrode voltage, the liquid crystal material is switched to the cholesteric state and absorbs incident light, whereas if the inverted-polarity voltage is out-of-phase with the scan electrode erase-write pulse, the intersection is switched to the nematic state and incident light is transmitted through the cell substantially without attenuation.

摘要： A multi-color liquid crystal display has a one-dimensional or two-dimensional array of at least one display cell, with a plurality of different liquid crystal host/guest dichroic dye compositions in each cell.

摘要： A control for use upon a solid panel, devoid of control shaft apertures, allows data entry by rotational positioning of a human member, such as one's finger, about a pattern of a plurality of interdigitated electrodes formed upon an interior surface of the panel. The position of the member varies the capacitance between adjacent ones of the electrodes, with position-decoding electronics energizing successive ones of the plurality of electrodes with successive phases of a master signal and recovering information relating the phase of the signal returned from the control to the position of the member. A light-emitting display may be positioned behind the panel to indicate the index of the control knob by a variable-length circular bar of light, a digitized display and the like.
