摘要： A variable color display device comprises a plurality of display areas arranged in a 7-segment font. Each display area includes at least two light emitting diodes for emitting upon activation light signals of respectively different primary colors and means for blending the light signals within the display area to obtain a composite light signal of a composite color. The light emitting diodes are selectively activated by pulses of substantially constant amplitude to display desired characters. Color control selectively controls the durations of the pulses to control the portions of the primary colors, to thereby control the color of the composite light signal.

摘要： A liquid crystal display is multiplexed by the digit input being driven between a first and second voltage level and the segment input being driven between the second and a third voltage level. The difference between the first and third voltage level is sufficient to activate the liquid crystal device. For AC liquid crystal displays, a polarity reversal circuit, driven by a low frequency signal, is included for both the digit input and the segment input to cause the digit input to vary between the second and third voltage level while the segment input varies between the first and second voltage level.

摘要： An improved digital display driving circuit is provided. The display includes first and second display digits, the first display digit and second display digit being respectively formed by a plurality of segment electrodes, at least one digit electrode spaced apart from the segment electrodes and material disposed between the segments electrode and the digit electrode. Regions of the material are adapted to be rendered visually distinguishable from adjacent regions by the application of an electric field across the region. The regions of the material in registration with the segment electrodes are rendered visually distinguishable in response to a predetermined potential difference being applied across any one of the respective spaced apart segment electrodes and the digit electrodes. The invention is characterized by the first digit electrode and second digit electrode being referenced during alternating driving intervals of time to a potential such that the regions of the material in registration therewith are prevented from being rendered visually distinguishable. Each of the segment electrodes forming the first digit are coupled to a corresponding segment electrode forming the second digit to define a plurality of segment electrode pairs. A memory includes a plurality of outputs coupled to each pair of segment electrodes to reference each pair of electrodes to one of a first drive potential and second drive potential to be compared during each driving interval of time with the potential of the respective digit electrodes spaced apart therefrom, and a shift register adapted to receive a drive signal and in response thereto write-in the drive signal to the memory prior to each driving interval of time.

摘要： An electronic timepiece wherein a quartz crystal oscillator produces a timekeeping standard signal which is divided by a transformer means formed of silicon gate complementary MOS transistor elements. The output of the transfer means is applied to a drive circuit which in turn is coupled to a digital display formed of liquid crystal elements. Time correction is performed by two switches, one switch selecting the digit of the display to be corrected, the other correcting the number displayed at the selected digit.

摘要： There is disclosed a battery powered wrist watch utilizing solid state circuits and a liquid crystal display to eliminate mechanical parts. Complementary metal oxide semiconductor (CMOS) devices are used to drive liquid crystal display cells. The liquid crystal cells dissipate only microwatts of power when energized and the CMOS devices require appreciable power only when switching from one state to the other. The combination of the liquid crystal display with the CMOS driving circuitry provides a low power, compact, portable watch.
