Individual electrodes other than the electrode group composed of the segment electrodes 6c are also formed as transparent electrodes, and transparent counter electrodes are provided at the opposing portions.

On the other hand, as shown in FIG. 4, the display unit 70 of the lower liquid crystal display panel 7 is roughly composed of three display areas 70a, 70b, and 70c.
In the first display area 70a, three ring electrode groups 71a, 71b, 71c are provided side by side. Among these, the ring-shaped electrode group 71a is composed of 12 segment electrodes 7c having the same shape. The second annular electrode group 71b is composed of five segment electrodes 7c having the same shape, and the third annular electrode group 71c is also composed of five segment electrodes 7c.

In the third display area 70c, electrode groups 73a, 73b, 73c, 73d, and 73e for expressing numbers from 0 to 9 are provided side by side. Each of these electrode groups is composed of seven segment electrodes 7c. In the third display area 70c, individual electrodes representing the characters "DST (Daylight Saving Time)", "A (AM)", "P (PM)", "ASZ (Snooze)" and other individual An electrode is provided.
Individual electrodes other than the electrode group consisting of the segment electrodes 7c are also formed as transparent electrodes, and transparent counter electrodes are provided at the opposing portions.

Thus, the upper liquid crystal display panel 6 and the lower liquid crystal display panel 7 have the same arrangement order of the corresponding electrode groups, and the upper liquid crystal display panel 6 and the lower liquid crystal display panel 7. The same contents can be displayed.
However, as shown in FIGS. 3A and 3B, the upper liquid crystal display panel 6 and the lower liquid crystal display panel 7 are different in the form (shape and size) of the electrode group including the segment electrodes. Yes.
That is, the electrode group composed of the segment electrodes 7c in the lower liquid crystal display panel 7 is configured in a planar manner, whereas that in the upper liquid crystal display panel 6 is the lower liquid crystal display as viewed from the front side. The planar electrode of the panel 7 is projected onto a sphere, and the size is larger than that of the lower liquid crystal display panel 7.
The segment electrodes 6c and 7c are also different in overall size. Therefore, when the two liquid crystal display panels 6 and 7 are driven alternately, a feeling that the display pops out or sinks is created.
That is, as shown in FIG. 3B, a voltage is applied to the segment electrode group 7c having a small overall size, and the liquid crystal portion at a position corresponding thereto is lit and displayed in a small size. When the electrode group 7c is turned off once, a voltage is applied to the segment electrode group 6c having a large overall size, and the liquid crystal portion at a position corresponding to the segment electrode group 6c is turned on and displayed in a large size. Since the portion is visually recognized first, and immediately after that, the large-sized liquid crystal portion is visually recognized, so that it is possible to obtain an impression that the time has jumped upward.
On the other hand, after that, a voltage is applied to the segment electrode group 6c having a large overall size, and the large segment electrode group 6c is once extinguished from a state in which the liquid crystal portion corresponding to this is lit and displayed in a large size. In the above, when a voltage is applied to the segment electrode group 7c having a small overall size and the liquid crystal portion corresponding to this is lit and displayed in a small size, the user first visually recognizes the large size liquid crystal portion, Immediately after that, a small-sized liquid crystal portion is visually recognized, so that an impression that the time has sunk downward can be obtained.
When two liquid crystal display panels 6 and 7 display the same content alternately, the effect is great.
In addition, in the upper liquid crystal display panel 6 and the lower liquid crystal display panel 7, the electrode groups corresponding to each other may be provided in a position where they overlap each other (rather, it is preferable to be provided in a position where they overlap each other). The electrode groups that do not correspond to each other are preferably provided at positions that do not overlap each other.

Next, the functional configuration of the electronic wristwatch according to the present embodiment will be described with reference to FIG.
The electronic wristwatch includes an input unit 100, a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, an oscillation circuit unit 104, a timing circuit unit 105, a display drive circuit unit 106, and the like. Configured.

  The input unit 100 includes a plurality of push button switches 11 for instructing execution of various functions of the electronic wristwatch. When the push button switch 11 is operated by the user, a time set (alarm time set or the like) or an animation mode is selected based on this.

  For example, the CPU 101 reads various programs stored in the ROM 102 in accordance with a predetermined timing or an operation signal input from the input unit 100, expands the programs in the work area of the RAM 103, and configures an electronic wristwatch according to the programs. Various processes such as instructions to each unit and data transfer are executed.

  The ROM 102 is a read-only memory and stores a system program, various application programs, various data, and the like for realizing various functions of the electronic wristwatch.

  The RAM 103 is, for example, a volatile semiconductor memory, and includes a memory area for temporarily holding various programs executed by the CPU 101 and data related to the execution of these programs, and is used as a work area for the CPU 101. It is done.

  The oscillation circuit unit 104 is a circuit that always outputs a clock signal with a constant frequency, and the time measuring circuit unit 105 counts signals input from the oscillation circuit unit 104 to acquire current time data and the like. The time measuring circuit unit 105 is configured to output the acquired current time data to the CPU 101.

  The display drive circuit unit 106 performs display processing for driving the liquid crystal display panels 6 and 7 based on data, control signals, and the like from the CPU 101 and displaying various information on the liquid crystal display panels 6 and 7, for example. Yes, and functions as a display control unit together with the CPU 101.

  Next, the operation of the electronic wristwatch according to the embodiment will be described together with the function of the CPU.

[Normal time]
FIG. 1 shows a normal display state of the electronic wristwatch. In this case, the CPU 101 drives only the lower liquid crystal display panel 7. The electronic wristwatch in the figure shows that it is currently 10:58:58 on June 21, 2001. At this time, the ring-shaped electrode 70a of the lower liquid crystal display panel 7 is turned on, indicating that the portion corresponding to the ten segment electrodes 7c is "10 o'clock", and the ring-shaped electrode 70b is formed on the five segment electrodes 7c. The corresponding portion is lit and indicates “50 minutes”, and the ring electrode 70b is lit and the portion corresponding to the five segment electrodes 7c is “50 seconds”.

[When setting time]
FIG. 5 shows a flowchart when the time is set.
The time setting is performed using the push button switch 11 of the electronic wristwatch. This time setting is performed, for example, when setting the current time, setting the alarm time, and the like. The CPU 101 sets the lower liquid crystal display panel (lower LCD) 7 to the lit state and the upper liquid crystal display panel (upper LCD) 6 to the unlit state before setting the time (NO in step 2), (step 1). The electronic wristwatch maintains a normal display state (see FIG. 1). When the CPU 101 is in the set state (YES in step 2), if the digit is not the set digit (NO in step 3), the lower liquid crystal display panel 7 is lit and the upper liquid crystal display panel 6 is disabled. The lamp is maintained in the lighting state (step 1). On the other hand, for the set digit (YES in step 3), the CPU 101 turns on the lower liquid crystal display panel 7 and disables the upper liquid crystal display panel 6 when the clock is an even number of seconds (NO in step 4). On the other hand, when the clock time is an odd number of seconds (YES in step 4), the lower liquid crystal display panel 7 is turned off and the upper liquid crystal display panel 6 is turned on (step 1). 5). In this way, when the set state is completed, the CPU 101 puts the lower liquid crystal display panel 7 into a lit state and the upper liquid crystal display panel 6 into a non-lighted state, and returns to the normal state.

  A display example in this case is shown in FIG. The set corresponding digit in this case is the “minute” digit, and the display of “58” in the “minute” digit is alternately switched between the lower liquid crystal display panel 7 and the upper liquid crystal display panel 6. Since the other portions are not set digits, the lower liquid crystal display panel 7 is lit and the upper liquid crystal panel 6 is not lit. Thus, if the shape and / or size of the display of the set corresponding digit is changed when the time is set, the position of the set corresponding digit can be easily confirmed. In addition, if the set corresponding digit is displayed intermittently, it becomes easier to confirm the set corresponding digit.

[When alarm sounds]
FIG. 7 shows a flowchart for the alarm reporting sound.
The alarm sounding timing is preset by the push button switch 11 of the electronic wristwatch. The CPU 101 sets the lower liquid crystal display panel (lower LCD) 7 to the lit state and the upper liquid crystal display panel (upper LCD) 6 to the unlit state before reaching the alarm reporting timing (NO in step 12) ( Step 11) The electronic wristwatch maintains a normal display state (see FIG. 1). When the alarm sounding timing comes (YES in step 12), the CPU 101 temporarily turns off the lower liquid crystal display panel 7 and turns on the upper liquid crystal display panel 6 (step 13). While the alarm sound continues (NO in step 14), the CPU 101 turns on the lower liquid crystal display panel 7 and turns on the upper liquid crystal display when the clock timing is an even number of seconds (NO in step 15). The panel 6 is turned off. On the other hand, while the alarm sound continues (NO in step 14), the CPU 101 turns on the lower liquid crystal display panel 7 and turns on the upper liquid crystal display when the clock timing is an odd number of seconds (YES in step 15). The panel 6 is turned off (step 16). In this way, when the alarm reporting is finished (YES in step 14), the CPU 101 returns to the process of step 11 to turn on the lower liquid crystal display panel 7 and turn off the upper liquid crystal display panel 6. Let

  A display example in this case is shown in FIG. In this case, the alarm sounding time is 10:58 on June 21, 2001. While this alarm reporting sound continues, the lighting state of the lower liquid crystal display panel 7 and the lighting state of the upper liquid crystal panel 6 are alternately repeated. As described above, when the alarm is notified (when the alarm is sounded, etc.), if the shape and / or size of the display is changed, it is easy to visually confirm the arrival of the alarm sound.

[Animation mode]
FIG. 9 shows a flowchart in the animation mode.
Here, for example, four electrodes arranged side by side and representing numbers are considered. The display digits of the four electrodes are considered as display digits A, B, C, and D in order from the left side.
This animation mode is selected by a key operation using the push button switch 11 of the electronic wristwatch. The CPU 101 keeps the lower liquid crystal display panel (lower LCD) 7 in the lit state and the upper liquid crystal display panel (upper LCD) 6 in the unlit state until the key is operated (NO in step 21). The electronic wrist watch maintains a normal display state. Then, when there is a key operation (YES in step 21) and 1/16 seconds have elapsed from the key operation (YES in step 22), the CPU 101 turns on the upper liquid crystal display panel 6 in the display digit A portion, and lowers it. In the other display digits B, C, D, the upper liquid crystal display panel 6 is turned off, and the lower liquid crystal display panel 7 is turned on (in the other display digits B, C, D). Step S23). Subsequently, when 2/16 seconds elapse from the key operation (YES in step 24), the CPU 101 turns off the upper liquid crystal display panel 6 and turns on the lower liquid crystal display panel 7 in the display digit A portion. At the same time, the CPU 101 turns on the upper liquid crystal display panel 6 in the display digit B portion and turns off the lower liquid crystal display panel 7 in the display digit B portion. The liquid crystal display panel 6 is turned off, and the lower liquid crystal display panel 7 is turned on (step 25).
In this manner, the lighting state of the upper liquid crystal display panel 6 and the non-lighting state 7 of the lower liquid crystal panel are sequentially transferred to the display digit A, the display digit B, the display digit C, and the display digit D at 1/16 second intervals. (Step 26). When 5/16 seconds have elapsed from the key operation (step 27), the upper liquid crystal display panel 6 is turned off and the lower liquid crystal display panel 7 is turned on in all display digits.

An example of the display in this case is shown in FIG. For example, this is an example in which a number “8888” composed of lowercase letters displayed in four digits increases in order (scrolled) from the left display digit. First of all, the most left of the display digit A is changed to "8" in the capital "8 888". Here, the numbers displayed as uppercase letters are underlined. Similarly, capital letters are underlined.
Next, at the same time as the display digit A returns to the lower case “8”, the display digit B changes to the upper case “ 8 ” to become “ 8 88 88”. Subsequently, the display digits B at the same time and return to the "8" in the lower case, display digit C is changed to "8" in the capital "88 8 8". Thereafter, the display digit C returns to the lower case “8”, and at the same time, the display digit D changes to the upper case “ 8 ” to become “888 8 ”, and then the display digit D returns to the lower case “8”. "

Another example of the display in this case is shown in FIG. For example, the number “8888” consisting of lowercase letters displayed in four digits is changed to “1111” by moving forward from the left display digit. First of all, the most left of the display digit A is changed to "1" in the case "1 888". Here, the numbers displayed as uppercase letters are underlined. Similarly, capital letters are underlined.
Next, at the same time as the display digit A becomes a lower case “1”, the display digit B changes to an upper case “ 1 ” to become “1 1 11”. Subsequently, the display digit B becomes a lower case “1”, and at the same time, the display digit C changes to an upper case “ 1 ” to become “11 1 8”. Thereafter, the display digit C changes to the lower case letter “1”, and at the same time, the display digit D changes to the upper case letter “ 1 ” to become “111 1 ”, and then the display digit D returns to the lower case letter “1”. It becomes.
In this way, by changing the display by scrolling one by one from the display by one of the liquid crystal display panels 6 and 7 one by one in order, it is possible to display a lively display.

As mentioned above, although embodiment of this invention was described, this invention is not limited to this embodiment.
For example, in the above-described embodiment, the example in which the present invention is applied at the time of time setting, alarm reporting, and animation mode has been described. However, when the tilt key is switched from OFF to ON, the driving of two liquid crystal display panels is appropriately controlled. Thus, it is possible to perform display such that the entire display or a part of the display jumps to the viewer side.
Further, only the lap time can be emphasized when the lap time is measured.
In the above embodiment, the display drive of the two-layer liquid crystal display panel is controlled to display such that the time jumps to the viewer side. However, the display drive of the three-layer or more liquid crystal display panel is controlled and visually confirmed. You may make it display so that time may jump out to the side.
