Description

[Detailed description of the invention]

The present invention relates to a crystal oscillation type composite display multi-function timepiece that has a single movement with an analog display mechanism using hands, a digital display mechanism using an electro-optical display device such as a liquid crystal cell or an electrochromic cell, and a pattern display mechanism. The development of crystal oscillation electronic wristwatches has been rapid, and their high reliability, good design, high precision, and low cost are widely known by users, and they have become a mainstream wristwatch. Quartz watches are classified into analog displays using hands, digital displays using liquid crystal display cells, and composite displays (analog-digital displays) that have the functions of both. Clocks with analog display have excellent design (rich digital variety), have a luxurious feel, are easy to tell the elapsed time and remaining time, and are easy to adjust, but it is difficult to make them multi-functional. Digital display watches have a simple internal mechanism and are low in cost.
The current time is displayed directly in numbers, a perpetual calendar,
Although it is easy to add multiple functions such as a stopwatch, timer, and alarm, it lacks the luxury of a pointer and has the disadvantage that it is difficult to tell the elapsed time and remaining time. Composite display watches are products that emphasize functionality and design, taking advantage of the strengths of each and compensating for each other's weaknesses. Composite display wristwatches have been proposed in the past, and some have been commercialized, but most of them have a rectangular liquid crystal display cell built into a part of the analog dial, which lacks design variety and makes the product unattractive. There were few. Watches with interesting designs have been commercialized, with the liquid crystal display cell having an irregular octagonal shape and an analog module placed in the notch, but the relationship and harmony between the analog and digital parts is weak, and the analog guideline is weak. The downside was that it was not in the center of the watch, and the hands were a little short, making it difficult to tell which mode the digital watch was in. The present invention improves the drawbacks of the above-mentioned conventional composite watches,
The analog pointer is in the center of the watch, and the length of the pointer is long, increasing the relationship and harmony between the analog and digital sections, making it easy to use as the digital usage mode can be seen at a glance, and the slim design makes the product very attractive. We propose a multi-display multi-function watch. The present invention provides a composite display multi-function watch that displays clock information and function information using hands and an electro-optical display device, in which the hands consist of at least a long hand and a short hand, and display clock information for hours and minutes in an analog manner. The digital display device has a numerical display section consisting of segments arranged in a Japanese character shape, etc., and an annular display section consisting of segments arranged in an annular shape around the pointer shaft, and the numerical display section has a numerical display section consisting of segments arranged in the shape of a Japanese character, etc. Clock information and functional information such as integration, subtraction, alarm time, etc. are displayed in numbers, and the annular display section displays clock information in seconds and information on the currently operating functions in patterns. Next, embodiments of the present invention will be described with reference to the drawings.

The upper polarizing plate 25 and the lower polarizing plate 26 are adhered, and a diffused reflection plate 27 is arranged. The twisted liquid crystal layer 24 usually has the property of rotating the plane of polarization, and when a voltage is applied between the segment electrodes 20 and the common electrode 22, the molecular arrangement of the twisted liquid crystal layer 24 changes and loses the property of rotating the plane of polarization. This mode of operation is called the TN-FE mode, and because it has low operating voltage, low power consumption, and can be driven in matrix mode, it is suitable for wristwatches, and this mode of operation is also suitable for the present invention. 4 and 5 are bottom (display surface side) and top (case back cover side) views, respectively, of assembled plan views of the module 28 with the case removed of the composite display multifunction wristwatch of the present invention.

Clock information such as minutes and stopwatch (integration),
Function information such as subtraction and alarm is displayed in numbers, and the annular display section displays seconds clock information and operating function information in patterns, so that the clock information for hours, minutes, etc. is displayed in analog form at all times. During normal use, the seconds are displayed on the annular display, when the function mode is called up, the function information is displayed in numbers on the numeric display, and when the function is in operation, the information on the function currently in operation is displayed in a pattern, so it is easy to use. Users can see at a glance which functions are in operation, and can also see hour and minute clock information at the same time.It is easy to use, has many function modes, is highly reliable, and is thin and inexpensive. A multi-function watch with a composite display is obtained, which has great practical effects. When in the stopwatch (integration) function mode, the cumulative time is displayed in hours, minutes, seconds, hundredths of a second, etc. on the numerical display, and the integrated time is displayed in clockwise cycles on the annular display at intervals of several tenths to several seconds. By displaying the functional information during the integration operation in a pattern, it can be seen at a glance that the stopwatch is in the process of integration. When in the timer (subtraction) function mode, the subtraction time such as hours, minutes, seconds, etc. is displayed in numbers on the numeric display, and the subtraction operation goes around counterclockwise at intervals of several tenths to tens of seconds on the annular display. By displaying the function information in a pattern, you can see at a glance that the timer is in the process of subtraction, and if you set it to go around counterclockwise every 60 seconds, you can see at a glance how many seconds are left. When in the alarm function mode, the hour and minute alarm time is displayed in numbers on the numerical display, and the alarm time is displayed in an analog pattern on the annular display using the alarm time as a guide. The remaining time until the alarm occurs can be seen at a glance based on the relative position of the alarm. Immediately after time-up in the timer (subtraction) function mode or alarm function mode, while the buzzer is emitting an alarm sound, the function information in the alarm is displayed in a pattern on the annular display that flashes at intervals of several tenths to several seconds. By doing so, you can see at a glance that a warning is in progress. The electro-optical display device is an annular display device, and an electro-mechanical converter, a wheel train, a pointer shaft,
By housing part or all of the hands and dial, a thin composite display watch can be obtained. To correct the pointer, use a switch to send a correction signal electrically.
Since it is an electromagnetic correction method in which corrections are made by inputting input to a mechanical converter, the analog block is small, thin, and has a simple structure with a small number of parts, easy assembly, and fewer failures, and the switch can be placed in any position. It can be placed easily, has a great degree of freedom in design, and has great practical effects. Furthermore, if the analog correction is made into a mechanical correction method, the winding stem that connects the external operating member such as the reuse and the pointer correction section has to overlap with the annular liquid crystal cell in cross section, which is not suitable for a thin structure. The modified method eliminates the need for winding stems, making it possible to achieve a thinner design. The electro-optical display device has a mode pattern of characters or marks corresponding to each mode of clock information and function information, and when each mode is sequentially selected by a switch, the mode pattern of each mode is displayed, making it easy to use and understand. A composite display multi-function watch is obtained.
