Description

[Detailed Description of the Invention] The present invention relates to an electronic digital display world clock that can display on a display panel the name of a place corresponding to the time being displayed.

Conventionally, world clocks have displayed the names of cities representing standard time in various parts of the world on the dial or on the outer case of the dial, and in the case of hand display watches, the city name printed on the disk etc. has been displayed on the dial. By adjusting it to the location, it mechanically increased or decreased the time difference and displayed the time in each location.

Furthermore, for electronic digital display wristwatches, a system has been devised in which the time in various parts of the world is calculated within an integrated circuit and displayed instantaneously.

In either method, a world clock must display the names of places around the world, and like the latter, electronic digital display wristwatches that can calculate the time in various parts of the world with a single touch are convenient for the user. However, I am struggling with how to display city names.

In other words, displaying many city names on the narrow surface space of a wristwatch by printing or other methods not only does not cover all the standard times in various parts of the world due to the limited number of numbers, but also requires the use of electronic digital watches. Even as a cutting-edge product design, it lacks smartness and is not appealing.

The purpose of the present invention is to provide a place name display that can be used in electronic digital world clocks, especially wristwatches, to display place names in a simple manner, and that can also be made into a smart format in terms of the design of the wristwatch.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

In Figure 1, 1 indicates the names of places representing standard time in various parts of the world corresponding to the time being displayed in segments 1a, 1b, 1c.
2.3.4 is an alphabet display section for displaying a three-letter abbreviated name, and 2.3.4 is a time display section, for example segment 2a.

2b displays hours, 3a and 3b display minutes, and 4a*4b displays seconds.

An example of place names displayed on the alphabet display section 1 is shown in FIG.

That is, in FIGS. 2a to 2ft, each T ok

Displayed abbreviated to characters.

In reality, the N of place names to be displayed should be 75 momme, which would cover as much standard time as possible in various parts of the world. If the arrangement is set to the minimum necessary segment arrangement that can display all the characters in the corresponding positions of each name, the alpha vent display section shown in FIG. 1 will be constructed.

The alphabet display section 1 can sequentially change place names using a changeover switch 5 shown in FIG. 1, and the time display sections 2, 3.4 display the standard time of the area represented by the place name.

The alphabet display section 1 is capable of displaying information other than place names, and after selecting a place name, for example, by using the changeover switch 6 in FIG. 1, the day of the week with an abbreviated English name is displayed.

Of course, the information is not limited to the day of the week.

As described above, in the present invention, a large number of place names, which are indispensable for a world clock, are displayed in common in an alphabet display section of only a few characters, so that the space required for place name display is small.

Particularly when used in wristwatches with limited display space, it is possible to display as many place names as possible to cover standard times around the world, and it is also possible to achieve a smart design suitable for digital watches.

Furthermore, since place names are not necessary in most cases after the standard time has been selected, there is also the advantage of being able to display other information on the alphabet display section.
