Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a liquid crystal or other display element in the display section, and displays many time information digits such as date, hour, minute, and second, which is more than the display digits of the display device. Regarding electronic watches that enable

An object of the present invention is to provide a method for reducing the number of drive output terminals and the number of segments of a display in an electronic timepiece, and another object of the invention is to provide an electronic timepiece with many functions.

Digital display is common in conventional electronic clock display methods, but when trying to display a lot of information at once, the number of display digits increases, and the number of drive output terminals and segments increases. There are drawbacks.

Also, the increase in the number of terminals and segments complicates the electronic circuit.

The present invention solves all of the above-mentioned drawbacks and reveals a method of displaying a large amount of information with a small number of display digits.

A first embodiment of the electronic timepiece according to the present invention has a liquid crystal or other display element in the display section, and includes date, day of the week, hours, minutes, seconds,
In an electronic watch that is capable of displaying three or more display items such as a fraction of a tithe, the display items can be appropriately ordered and several of the displayable items can be displayed in duplicate by operating a switch. It is characterized by displaying the information in sequence.

The second embodiment differs from the first embodiment in that the switch operation can reversibly change the direction in which the displayed items are sent.

Furthermore, a third embodiment is the same as the first one, and includes the fact that the last displayed digit or the last displayed item is corrected by a time correction switch.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the segment arrangement of the display of an electronic timepiece with a daylight exit and capable of displaying hours, minutes, and seconds.

All segments are classified into the following seven segment groups.

From left to right: day of the week display support group 10, first digit group 11.
Group 12 for second digit, Group 15 for first unit display, Group 1 for third digit
3, a fourth digit group 14, and a second unit display group 16.

Further, segment groups 10, 15, and 16 each consist of three segments, and segment groups 11, 12, 13, and 14 each consist of seven segments, making a total of 37 segments.

FIG. 2 shows a specific example of day of the week display and unit display.

The unit display uses segment groups 15 or 16.

Segment selection 20 represents units of minutes, selection 21 represents units of hours, and selection 22 represents units of days.

Furthermore, segment groups 10 and 11 are used to display the day of the week.

Segment selection 23 represents Su (Sunday), selections 24, 25, 26° 27.2B, 29 respectively represent Mo
(Monday), Tu (Tuesday), We (Wednesday), Th
(Thursday), Fr (Friday), Sa (Saturday),
represents.

Figure 3 shows 18:56:34 on Sunday 27th in 6 formats.

Display 31 is Sunday, display 32 is Sunday 27th, display 33
indicates 18:00 on the 27th, display 34 indicates 18:56, display 35 indicates 56 minutes 34 seconds, and display 36 means no display.

Actually, the display is changed by switch operation from 31→32→33→
It may be changed as 34→35→36→31, or conversely as 31→36→35→34→33→32→31.

In other words, since it involves sequentially displaying two items at a time, overlapping each other, by operating a switch, each item can be displayed with a small number of display digits.

Also, the overlap reduces the sense of discontinuity when the display changes.

Furthermore, it is possible to continue displaying only the desired display items, such as a calendar only, hours and minutes only, etc.
It may also be dedicated to minutes and seconds.

By enabling a non-display state, it is possible to save power by not displaying the display when not observing.

FIG. 4 is a front view of an electronic timepiece to which the present invention is applied.

The electronic timepiece 40 has a digital display 41, a changeover switch button 42, a left digit feed/negative correction switch 43, and a left digit feed/positive correction switch 44.

In this embodiment, since there are two types of switches, one for the left and one for the right, the switch operation is reversible for the display item shift.

The display changes are 31 → 32 → 33 → 34 → 35 → 36 →
31, and the movement operation to the desired display can be performed quickly.

Furthermore, by operating the changeover switch button 42, the switches 43 and 44 change their roles for shift and correction.

If the time of the last displayed digit or the last displayed item is corrected by a correction switch, the correction can be made while looking at the display, resulting in good operability.

Explaining this with reference to FIG. 3, the display 31 allows correction of the day of the week, 32 the date, 33 the hour, 34 the minute, and 35 the second.

In the embodiment of FIG. 4, two switches are used for opposite corrections.

In other words, the negative adjustment switch 43 is used for retarding adjustment, and the positive adjustment switch 44 is used for advancing adjustment, making it possible to quickly adjust the time and further improve operability.

As described above, according to the present invention, it is possible to provide a display method for an electronic timepiece that provides a large amount of information with a small number of display digits.

In particular, if applied to small wristwatches, it will be possible to manufacture watches with many functions with a small display, and the value of the application will increase.
