The light source is moved relative to the surface by the clock mechanism on either a twelve or twenty-four hour cycle. A gnomon is disposed in such a position relative to the surface that the light source causes a shadow of the gnomon to be cast onto the surface. As the light source moves relative to the surface, the shadow moves across the time interval markings, and time can be read off the timepiece by observing the position of the shadow relative to these markings.

The main display portion requires 48 display elements, and the auxiliary display portion requires 4 elements, compared to 120 elements required in conventional time displays. Through this reduction in the number of elements, a small-sized, low-priced display apparatus can be achieved.

  • Patent number: 4407587
    Abstract: A plurality of liquid crystal display elements are radially arrayed, display elements corresponding to preset time are kept turned on, and lapse of time is successively and selectively displayed, so that the remaining time and the lapse of time can be quickly recognized from a mutual relation between the lapse of time and the preset time. Furthermore, the display elements are divided into two in the radial direction so that the preset time and the lapse of time can be displayed by the display elements which have been divided. Moreover, the time display unit displays the time in a flashing manner, such that the lapse of time and the like can be recognized more easily.

  • Patent number: 4385842
    Abstract: An electronic watch having a liquid crystal display which presents time information in a substantially conventional presentation of hour, minute and second hands which appear to circulate around the watch face. The display contains sixty equidistant radial hands on an outer circle for the display of both minutes and seconds, and twenty-four equidistant radial hands on an inner circle for the display of hours and half hours. The hands are divided into sets, and each hand in each set is interconnected to form strings of hands with each string having no more than one hand in a set. The circuit interconnections of the hands are provided on a surface of a substrate of the display without crossover of the connecting leads. A parallel substrate has formed thereon transparent electrodes each associated with and overshadowing a set of hands.

  • Patent number: 4370068
    Abstract: An hour and minute display for an electronic chronometer includes a plurality of first indicators positioned in spaced relation about the perimeter of a closed geometric figure. The first indicators are actuatable to indicate the hour. A plurality of second indicators are positioned about a closed geometric figure adjacent the first indicator. The second indicators are selectively actuatable to indicate minutes past the hour in 5-minute increments. Also positioned adjacent the first indicators is a third indicator capable of being actuated to selectively indicate increments of one, two, three or four minutes past the displayed 5-minute increment. The first, second and third indicators are preferably driven by digital counter circuits commonly employed in conventional electronic chronometers.

  • Patent number: 4367959
    Abstract: A circuit for producing a numerical signal representative of the value of the physical parameter which is to be displayed and which can assume a given number of values. The signal is applied to a decoder for controlling the display cell.The decoder is so arranged as to render visible a single display element for certain values of the numerical signal and two adjacent elements for other values. The cell therefore comprises a small number of display elements than there are different values to be displayed.

  • Patent number: 4364672
    Abstract: A method for driving a liquid crystal display element so as to give a simultaneous analogue display of 3 kinds of information. The liquid crystal display element is driven over 1/3-duty periods by applying 4 kinds of voltage waveforms to one electrode formed on one of paired substrates, and at least 5 kinds of voltage waveforms to the other electrode on the other substrate, said electrodes being divided into a multiplicity of electrode patterns. In particular, one of the 4 kinds of voltage waveforms applied to the electrodes of one of said substrates is set to provide an OFF condition for the display regardless of which of the at least 5 voltage waveforms is applied to the electrodes of said other substrate. In this driving method only one chip of the element driving LSI is sufficient for a simultaneous analogue display of 3 kinds of information e.g. hour, minute, and second.

  • Patent number: 4362398
    Abstract: An LCD analog timepiece employs a multiplexing driving circuit to supply voltages to the liquid crystal display segments in the proper sequential relationship so as to activitate the desired portions of the display in time-multiplex fashion to show hours, minutes and seconds. The multiplex driving circuit connects a minimum number of combinations of simple waveforms in proper phase to one or more of 16 strings of radial segments and to one or more of 8 backplane segments in a prescribed manner. Special radial segments are located so as to straddle the juncture of the backplane segments, in order to simplify circuit connections for using an hour hand which appears to be three segments wide.

  • Patent number: 4326279
    Abstract: An analogue display includes an electrical sensitive medium enclosed between two sets of electrodes. The two sets of electrodes are registered and overlap to provide background and one or more shaped index characters, each at a plurality of selectable positions. Voltage signals are applied to the electrodes so that the medium is held in an OFF state in the region between selected electrodes, while simultaneously voltage signals are applied so that in other regions of the medium, the medium is in an ON state. The medium may be of liquid crystal, electroluminescent or gaseous material. One set of electrodes may have a meander configuration, the other set a segmented configuration. The index character or characters may be displayed at one, two or three positions, each character being of different shape, for meter or timepiece applications. The voltage signals applied may be binary coded and in preference pseudo-random sequence binary codes.
