A variable color optical device comprises three light emitting diodes for emitting upon activation light signals of respectively different primary colors and means for blending the light signals to obtain a composite light signal of a composite color. The light emitting diodes are substantially simulteneously activated by pulses of a substantially constant amplitude. 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 emitted from the optical device.

An electro-optical display element for a multiplexing system has a first and a second electrode substrate opposed to each other and an electrically responsive optical member provided between the two electrode substrates. Each of the two electrode substrates has combinations of ten segments, which are, in order from above, first, second and third lateral segments juxtaposed, a longitudinal upper left segment, upper middle segment and upper right segment juxtaposed between the first segment and the second segment, and a longitudinal lower left segment, lower middle segment, lower right segment juxtaposed between the second and third segments and a point segment for displaying the decimal point. The first electrode substrate has a first, a second and a third signal terminal. The second electrode substrate has a first, a second and a third scanning terminal. The signal terminals and the scanning terminals are specifically connected.

An electro-optical display comprises an electrochromic material and a predetermined number of display segments, each combination of the display segments defining a different desired display pattern. Lead-in electrodes connected to the respective display segments for driving purposes are shaped in such a manner as to have resistance values inversely proportional to the size of the corresponding display segments.

A fully electronic chronometer using a quartz crystal as a frequency standard and displaying mean time by the use of electronically operated digital read-outs. The circuit permits the display of the instant of time at which a switch is operated, while mean time continues to be counted by the circuitry. Other features include conservation of power by display of mean time only upon demand and the provision for control and display remote from the timing circuitry.

A device for providing an electro-optical display of time comprises an electronic timekeeper fed by a voltage source and including a time base and a frequency divider. An electro-optical display is formed of groups of electro-chromic cells each able to take two different visual aspects. The cells are controlled by a code converter supplying state variables corresponding to the desired aspects of the cells to provide a display of time. One aspect of the cells corresponds to a stable state, the other aspect to a quasi-stable state which in order to be maintained, requires very low or zero power. Transition of a cell from one state to another requires precisely determined amounts of energy. A change detector supplies to a selector, data to actuate the operations of inscription and erasure of the display cells. The selector dispenses the required amounts of energy supplied to the display to ensure correspondence between the state variables delivered by the code converter and the aspect of the corresponding display cells, in a manner ensuring transition from one state to another with a minimum supply of energy.

A digital electronic timepiece wherein a fundamental frequency signal is divided into a pulse signal of 1 Hz corresponding to one second. Said pulse signal is applied to a plurality of cascade connected counters, corresponding to second, minute and hour, each of said counters being connected to a matrix circuit for converting the output binary code rows from the respective counters to binary code rows corresponding to segments of the time display device, the output of each of said matrix circuits being applied to a selection circuit for actuating selected segments of each unit of the time display device in response to the output binary code from the respective matrix circuit. The display device consists of a liquid crystal display panel having a plurality of time display units each of which is divided into a plurality of segments arranged so that respective combinations of each segments of each time display units represent all digits from 0 to 9.
摘要:
The disclosure is directed towards systems and methods for dimming an alarm clock with three displays. An alarm clock can include three displays each positioned on a different side of the alarm clock to allow the alarm clock to be read from different vantage points. In some implementations, the alarm clock can include a front display, a right side display, and a left side display. Each display can have multiple brightness settings. Each display also can have a respective dimming button to allow a user to select a desired brightness level. In some implementations, the dimming button for the front display can serve as a master dimming button by controlling the brightness of all three of the displays, while the right side dimming button and the left side dimming button control only the brightness setting for the right side display and the left side display, respectively.
