Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electro-optical analog display clock that displays, for example, the time in Japan and the time in a foreign country with a time difference on the same time display section.

BACKGROUND ART A single watch that displays two times has been known for some time. For example, an analog display type timepiece is a mechanical timepiece that has two pairs of hands consisting of two hour hands and two long hands, and each pair of hands has a different color. In addition, digital display type using liquid crystal etc.
A first time display section and a second time display section were provided at different locations, or two time displays were performed by switching from the first time display to the second time display at the same location.

According to the present invention, an electro-optical substance such as a liquid crystal is used to display two displays at the same time on the same display screen using an analog display, and the display is easy to see and no extra display means is required. It provides watches.

Examples of the present invention will be described.

In the first diagram, two sheets of sealing glass 1 and 2 face each other with a certain distance therebetween, and an electro-optical material 3 such as liquid crystal or electrochromic is sealed within this gap. On the opposing surface of the sealing glass 1, as shown in the second figure, six fan-shaped inner full-surface electrodes 4 and six fan-shaped outer full-surface electrodes 5 are formed on the outside thereof. Electrodes 6 are drawn out and connected to respective external terminals (not shown). On the opposing surface of the sealing glass 2, as shown in the third figure, 60 inner display pixels 7 are arranged radially to face the six inner full-surface electrodes 4. On the outer extension of this inner display pixel 7, 60 outer display pixels 8... are connected to the six outer whole surface electrodes 5...
It is placed opposite to. The inner display pixels 7 and the outer display pixels 8 at predetermined positions are sequentially connected by lead electrodes 9 . . . 10 lead electrodes 10
It is connected to an external terminal (not shown) via...

The fourth illustration is a front view of a watch with two displays, in which a scale 11 that divides the circumference into 60 equal parts and a numeral 12 that indicates from 1 o'clock to 12 o'clock are formed on the front of the sealing glass 1. be. The first display is the first clock displayed by the inner display pixels 7, and in this example, it is 10:10.
It shows minutes and 30 seconds. The second display is a second clock displayed by the outer display pixels 8, and in this example shows 8:10:30. That is, the hour display of the first clock indicates 10 o'clock by the inner display pixel 7a, the minute display of the first clock indicates 10 minutes by the inner display pixel 7b, and the second display of the first clock indicates the time by the inner display pixel 7b. 7c indicates 30 seconds. Furthermore, the hour display of the second clock indicates 8 o'clock by the outer display pixel 8a, the minute display of the second clock indicates 10 minutes by the outer display pixel 8b, and the second display of the second clock indicates the time by the outer display pixel 8b. 8c indicates 30 seconds. In this example, the first clock displays the local time, and the second clock displays the time in another city with a two-hour time difference. Since the time difference is 2 hours, each minute display pixel 7b and 8b and each second display pixel 7
c and 8c line up in a line, making it look like a long hand.

In the first and second clocks, the hour display and the minute display are displayed in different states; in the case shown in the fourth figure, the number of selected pixels is 1 each; The pixels 7a and 8a are turned on and the other minute display pixels 7b and 8b are turned on and off to create different states.

In the case shown in Figure 5, the hours of the first clock are displayed using inner display pixels 7d and 7e, and the hours of the second clock are displayed using outer display pixels 8d and 8e. Different states are created by different numbers of selected pixels.

In the case shown in Fig. 6, the first clock is the inner display pixel 7f.
and 7g, 7h, and 7c indicate 10:05 minutes and 30 seconds, and the second clock is displayed on outer display pixels 8f, 8g, and 8.
h, 8c indicates 8:35:30. Therefore, the second clock shows that there is a time difference of one and a half hours behind the first clock.

Further, in the fifth and sixth diagrams, depending on whether the hour is in the morning or in the afternoon, one is displayed in a lit state and the other is displayed in a blinking state. Now, when AM is lit and PM is blinking, for example, in FIG. 5, pixels 7d and 7e of the first hour display are lit and pixels 8d and 8e of the second hour display are blinking, then the first clock is The time is 10:10:30 a.m., and the second clock is 8:10:30 p.m., so the time difference is 10 hours ahead. In other words, the 12-hour analog display allows the second clock to display the time in an area with a time difference of up to 24 hours.

As described above, according to the present invention, it is possible to perform two displays at the same time using an analog display without increasing the number of display pixels.Moreover, since the display is always displayed, the display is easy to see, and it is easy to see the context and quantity. It's easy to get a feel for it. Furthermore, the time at the desired location and the time at another location can be easily identified, and there is no confusion between the two.

Claims (1)

[Claims] 1. 60 inner display pixels made of electro-optical display elements are arranged radially, outer display pixels are arranged radially outside each inner display pixel, and the inner display pixels are arranged radially. Therefore, the first means for displaying the hours and minutes of the time at the desired location in different display modes, and the outer display pixels display the hours and minutes of the time at a different location with a time difference from the desired location. and second means for displaying minutes in different display modes.
