DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device for displaying a tide peak graph on a liquid crystal display device and an electronic timepiece equipped with the liquid crystal display device.

[0002]

2. Description of the Related Art An electronic timepiece for displaying a tide height graph on a liquid crystal display device is a liquid crystal display device having a tide-only segment 71 for displaying a tide height graph on a liquid crystal as shown in FIG. Is a segment dedicated to the time calendar for displaying the time calendar in a liquid crystal display. The tide wave height graph and the time calendar are displayed using two segments 71 and 72.

[0003]

However, in the above prior art, the tide height is displayed on a liquid crystal display device having a dedicated liquid crystal display segment for displaying only the tide height. Cannot be displayed. In addition, in order to display other information, it is necessary to prepare a display segment in addition to the tide height display segment, and by preparing a segment other than the tide display, each display segment of the liquid crystal display device can be displayed. In order to fit on the display surface of the liquid crystal display device, the display area of each segment for displaying information has to be reduced,
When many other information display functions are mounted on a timepiece, there is a disadvantage that the area of each information display becomes small and it becomes difficult to see.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a tidal wave height graph and information other than the tidal wave height while maintaining a maximum display area of each display segment on a limited display surface of a liquid crystal display device. Is to be displayed.

[0005]

In order to solve the above problems, a liquid crystal display device of the present invention and an electronic timepiece provided with the liquid crystal display device employ the following configuration.

A liquid crystal display device according to the present invention is characterized in that a tide wave height graph is displayed in a display segment having a dot matrix configuration format.

An electronic timepiece provided with a liquid crystal display device according to the present invention is characterized in that the electronic timepiece is provided with a liquid crystal display device that displays a tide wave height graph in a display segment having a dot matrix configuration format. It is characterized in that information other than the tide wave height graph is displayed by using the graph.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, an electronic timepiece according to a best mode for carrying out the present invention will be described with reference to a display diagram of a liquid crystal display device provided in the electronic timepiece of FIG. FIG. 1 shows a liquid crystal display device of a dot matrix configuration type provided in an electronic timepiece according to an embodiment of the present invention, which displays a tide height graph display 11 and a date display 12 at which the tide height of the tide height graph is displayed. It is a display figure. Further, when today's date is selected in the date display 12 and the tide wave height graph of the present day is displayed in the tide wave height graph display 11, the tide height graph corresponding to the current time of the day (for example, 13:00) is displayed. One row displays the current time corresponding wave height blink 6
By blinking the display as shown in FIG. 6, the tide wave height at the current time on the current date can be notified as shown in FIG. FIG. 2 is a liquid crystal display device of a dot matrix configuration type provided in the electronic timepiece according to the embodiment of the present invention.
FIG. 4 is a time / day of the week display diagram displaying information of 1 and day of the week display 22. FIG. 3 shows a liquid crystal display device of a dot matrix configuration type provided in the electronic timepiece according to the embodiment of the present invention.
FIG. 9 is a calendar display diagram displaying calendar information including day information in a calendar display 31 and a day display 32. FIG. 4 shows a liquid crystal display device of a dot matrix configuration type provided in an electronic timepiece according to an embodiment of the present invention, and includes a time display 41, a day display 42, and an animation display 43.
FIG. 7 is a time, day of the week, and animation display diagram simultaneously displaying three pieces of information. FIG. 5 is an all-lit display diagram showing all segments in the liquid crystal display device of the dot matrix configuration type provided in the electronic timepiece according to the embodiment of the present invention. The upper dot segment 51, the middle dot segment 52, and the lower dot It consists of a segment 53. The lower dot segment 53 has 24 horizontal dots so that the tide wave height graph can be displayed at an hourly resolution.

In the embodiment of FIG. 5, the upper, middle and lower display surfaces of the liquid crystal display device are composed of dot segments 51, 52 and 53 each having an independent dot matrix structure. The liquid crystal display device provided in the electronic timepiece only needs to have at least one part of the dot segment of the dot matrix configuration type (for example, one of the dot segments 51, 52, and 53), and the other display stages have the display of the seven-segment configuration. It may be a segment. In FIG. 5, the tide height graph display 11 shown in FIG. 1 is displayed using the lower dot segment 53. Since the lower row is composed of display segments in a dot matrix configuration format, the time information shown in FIG. 2 can also be displayed as the time display 21, and the month and day information of the calendar display 31 shown in FIG. Can also be displayed.

In the above-described embodiment, an example in which time information is displayed in addition to the liquid crystal height graph with a display segment having a dot matrix configuration format for displaying a liquid crystal height graph, an example in which calendar information is displayed, and an example in which animation is displayed. However, the present invention is not limited to this, and any information may be used as long as the information can be displayed in a display segment in a dot matrix configuration format.

In the above embodiment, a digital electronic timepiece having only a liquid crystal display device has been described. However, the present invention is also effective for a combination type electronic timepiece having hands.

[0012]

According to the present invention, an electronic timepiece displaying a tide wave height graph,
Equipped with a liquid crystal display device that displays the tidal wave height graph with display segments in the dot matrix configuration format, it is possible to display information other than the tidal wave height graph in that display segment, and the number of display segments other than the conventional tide display Can be reduced, the area of each display segment can be maximized for each display mode in a limited range of the display surface of the liquid crystal display device, and the display of each information can be easily viewed.
