Description

Technical Field

[0001] The present invention relates to a wristwatch.

Background Art

[0002] There is known a wristwatch having a novel value not found in the past (see, for example, Patent Documents 1 and 2). FIG. 33 is a diagram showing a conventional wristwatch 900 for explanation. The wristwatch 900 shown in FIG. 33 is the wristwatch described in FIG. 13 of Patent Document 2. In FIG. 33, FIG. 33(a) is a perspective view of the wristwatch 900 at the time of display, and FIG. 33(b) is a perspective view of the wristwatch 900 at the time of non-display. As shown in FIG. 33, when the wristwatch 900 is in the non-display state, no display is made, not even a time display. Therefore, although it is a wristwatch, it becomes a wristwatch that does not make the wearer conscious of the presence of the time display when in the non-display state, and provides a new value to the wristwatch.

BEST MODE FOR CARRYING OUT THE INVENTION

[0029] Hereinafter, each embodiment of the present invention will be described. FIG. 1 is a diagram showing a state in which the wristwatch 1 according to the embodiment is worn on the left wrist of a user. In FIG. 1, arrow A indicates the direction of the line of sight when the user views the wristwatch 1 worn on the wrist of the left arm. That is, when the user views the wristwatch 1 worn on the wrist of the left arm, it is common for the user to view the wristwatch 1 with the elbow of the arm bent slightly toward the user's body (abdomen or chest side), and the direction of the line of sight at this time is indicated. In FIG. 1, arrow A is drawn in the horizontal plane direction, but in general, the actual line of sight direction is diagonally downward from the user's eyes.

[0030] FIG. 2 is an enlarged view showing the wristwatch 1 worn on the user's arm as shown in FIG. 1. FIG. 2(a) is an enlarged view of the wristwatch 1 worn on the user's arm when viewed along the direction of arrow A in FIG. 1, and FIG. 2(b) is an enlarged view of the wristwatch 1 worn on the user's arm when viewed along the direction of arrow B (substantially opposite to arrow A) in FIG. 1. In FIG. 2, a state is shown in which the wristwatch 1 displays the time in an analog clock display mode represented by an hour hand and a minute hand. Also, FIG. 2 is also a diagram showing the first display mode of the wristwatch 1 according to the embodiment. The first display mode will be described later.

[0031] FIG. 3 is a diagram showing the watch body 100 of the wristwatch 1 according to the embodiment and the display unit 200 formed on five surfaces excluding the lower surface of the watch body 100. FIG. 3(a) is a perspective view of the watch body 100, and FIG. 3(b) is a plan view showing the display unit 200 of the wristwatch 1 developed into five display units 210 to 214.

[0032] With reference to FIGS. 1, 2, and 3, the configuration of the wristwatch 1 according to the embodiment will be described. The wristwatch 1 according to the embodiment includes a rectangular parallelepiped watch body 100, five display units 210 to 214 formed over the entire area of five surfaces (the upper surface and four side surfaces) excluding the lower surface facing the user's wrist side among the six surfaces constituting the surface of the watch body 100, a belt 300 for attaching the wristwatch 1 to the user's wrist, and a display control unit 450 (the display control unit 450 will be described later with reference to FIG. 4) for controlling the display of each of the five display units 210 to 214. In the present invention, "formed over the entire area" means that it is sufficient if it appears to be formed over the entire area as seen from the user, and it does not necessarily have to be formed over the entire area in a strict sense.

[0033] As shown in FIG. 3(a), the watch body 100 has a rectangular parallelepiped shape with a predetermined thickness t, and five display units 210 to 214 are formed on five surfaces, namely, the upper surface 110 on the side opposite to the lower surface and the four side surfaces (the first side surface 111, the second side surface 112, the third side surface 113, and the fourth side surface 114). In the five display units 210 to 214, the display unit formed on the upper surface 110 of the watch body 100 is the upper surface display unit 210, the display unit formed on the first side surface 111 of the watch body 100 is the first side surface display unit 211, the display unit formed on the second side surface 112 of the watch body 100 is the second side surface display unit 212, the display unit formed on the third side surface 113 of the watch body 100 is the third side surface display unit 213, and the display unit formed on the fourth side surface 114 of the watch body 100 is the fourth side surface display unit 214.

[0034] The five display units 210 to 214 are composed of five organic EL (Electro Luminescence) display sheets. That is, the upper surface display unit 210 is composed of an organic EL display sheet for the upper surface, the first side surface display unit 211 is composed of an organic EL display sheet for the first side surface, the second side surface display unit 212 is composed of an organic EL display sheet for the second side surface, the third side surface display unit 213 is composed of an organic EL display sheet for the third side surface, and the fourth side surface display unit 214 is composed of an organic EL display sheet for the fourth side surface.

[0035] In the following description, when the five display units 210 to 214 are described as the corresponding organic EL display sheets respectively, the same reference numerals as the five display units 210 to 214 shall be used for each organic EL display sheet, such as the organic EL display sheet for the upper surface 210, the organic EL display sheet for the first side surface 211, the organic EL display sheet for the second side surface 212, the organic EL display sheet for the third side surface 213, and the organic EL display sheet for the fourth side surface 214.

[0036] In addition, when the organic EL display sheet for the upper surface 210, the organic EL display sheet for the first side surface 211, the organic EL display sheet for the second side surface 212, the organic EL display sheet for the third side surface 213, and the organic EL display sheet for the fourth side surface 214 are described together, they may be expressed as "each organic EL display sheet 210 to 214". Also, when the organic EL display sheet for the first side surface 211, the organic EL display sheet for the second side surface 212, the organic EL display sheet for the third side surface 213, and the organic EL display sheet for the fourth side surface 214 are described together, they may be expressed as "each side surface organic EL display sheet 211 to 214".

[0037] Each of these organic EL display sheets 210 to 214 is pasted one by one on the upper surface 110 of the watch body 100 and four side surfaces (the first side surface 111, the second side surface 112, the third side surface 113, and the fourth side surface 114). Thereby, the watch 1 as shown in FIGS. 1 and 2 is configured. In FIGS. 1 and 2, a state in which analog time display is made is shown. However, when nothing is displayed, it becomes plain over the entire display unit 200. The plain here means that not only analog clock display but also digital clock display and various displays are not performed.

[0038] In this case, five organic EL display sheets (each of the organic EL display sheets 210 to 214) are pasted one by one on the watch body 100 to form the display unit 200. By doing so, the corners of the watch 1 (the corners formed by the upper surface organic EL display sheet 210 and the side surface organic EL display sheets 211 to 214) can be made right angles, and the flatness of each of the organic EL display sheets 210 to 214 can be increased, so that it looks neat.

[0039] Also, on the five surfaces of the watch body 100, that is, the upper surface 110 and the four side surfaces (the first side surface 111, the second side surface 112, the third side surface 113, and the fourth side surface 114), a first electrode group 120 for supplying power and electrical signals to each of the organic EL display sheets 210 to 214 is provided so as to be exposed. On the other hand, on the back surface of each of the organic EL display sheets 210 to 214, a second electrode group 220 for receiving power and electrical signals from the first electrode group 120 is provided at a position corresponding to the first electrode group 120. And the first electrode group 120 of the watch body 100 and the second electrode group 220 of each of the organic EL display sheets 210 to 214 are electrically connected to each other between the corresponding electrodes. Further, on the back surface of each of the organic EL display sheets 210 to 214, a drive circuit for supplying an electrical signal for controlling the lighting state of each pixel of each organic EL display sheet is provided. In FIG. 3, the illustration of the drive circuit is omitted.

[0040] FIG. 4 is a diagram showing, as a functional block diagram, the configuration of a control system for operating the wristwatch 1 according to the embodiment. Note that the functional block diagram shown in FIG. 4 shows the functional blocks mainly necessary for performing display among the various functions of the wristwatch 1 according to the embodiment.

[0041] On the side of the wristwatch body 100, there are a display image selection unit 410 as a user interface for the user to select what kind of display to perform on the five display units 210 to 214 (each organic EL display sheet 210 to 214), an image data storage unit 420 that stores images to be displayed on each organic EL display sheet 210 to 214, a synchronization signal generation unit 430 that generates a synchronization signal for synchronizing among the organic EL display sheets 210 to 214 so that the images to be displayed on the organic EL display sheets 210 to 214 are linked or related images, a time data generation unit 440 that generates current time data, and a display control unit 450 that controls the display of each of the organic EL display sheets 210 to 214. Note that the images to be displayed on each organic EL display sheet 210 to 214 may be images stored in the image data storage unit 420, images generated by an image data generation unit (not shown), or images received from the outside via communication. For example, they may be images from the user's smartphone or images from a contracted video distribution company.

[0042] On the other hand, on the side of the display unit 200, there are a drive circuit 510 for the upper surface organic EL display sheet 210, a drive circuit 511 for the first side surface organic EL display sheet 211, a drive circuit 512 for the second side surface organic EL display sheet 212, a drive circuit 513 for the third side surface organic EL display sheet 213, and a drive circuit 514 for the fourth side surface organic EL display sheet 214.

[0043] Note that, although not shown in FIG. 4, on the wristwatch main body 100 side, a power supply unit for supplying power to each functional block shown in FIG. 4 is also provided. Power from the power supply unit and various signals from the display control unit 450 are supplied via a first electrode group 120 provided on the wristwatch main body 100 side (see FIG. 3(a)) and a second electrode group 220 provided on each of the organic EL display sheets 210 to 214 side (see FIG. 3(c)).

[0044] The display control unit 450 reads out the image stored in the image data storage unit 420 based on the content selected by the user from the display image selection unit 410, and performs control to display the read image on each of the organic EL display sheets 210 to 214. At this time, the display of each of the organic EL display sheets 210 to 214 is controlled so that the images to be displayed on each of the organic EL display sheets 210 to 214 are interlocked or related.

[0045] As described above, the display control unit 450 performs control to display the image read from the image data storage unit 420 on each of the organic EL display sheets 210 to 214. However, at the time of starting up the wristwatch 1 according to Embodiment 1, control is performed to display a display image selection screen that functions as the display image selection unit 410. When the display image selection screen is displayed on the wristwatch 1, the user can select the content to be displayed from the displayed display image selection screen. Then, the display control unit 450 controls the display based on the display mode selected by the user. Note that the display image selection may be performed from the selection screen of the user's smartphone that is linked with the wristwatch.

[0046] For example, when the user selects the analog time display from the display image selection unit 410, the five display units 210 to 214 of the wristwatch 1 according to the first embodiment enter the analog time display mode. The display control unit 450 reads the current time data from the time data generation unit 440 and controls the drive circuits 510 to 514 of the organic EL display sheets 210 to 214 so as to display the current time by the hour hand and the minute hand on each of the organic EL display sheets 210 to 214 as shown in FIG. 2. Note that the selection of the display image may be performed from the selection screen of the user's smartphone linked to the wristwatch. The specific manner of displaying the time in the analog time display mode will be described later.

[0047] Incidentally, as described with reference to FIG. 3, each of the organic EL display sheets 210 to 214 is attached to each of the five surfaces out of the six surfaces constituting the surface of the wristwatch body 100, excluding the lower surface. That is, the upper surface organic EL display sheet 210 is attached to the upper surface 110 of the wristwatch body 100, the first side surface organic EL display sheet 211 is attached to the first side surface 111 of the wristwatch body 100, the second side surface organic EL display sheet 212 is attached to the second side surface 112 of the wristwatch body 100, the third side surface organic EL display sheet 213 is attached to the third side surface 113 of the wristwatch body 100, and the fourth side surface organic EL display sheet 214 is attached to the fourth side surface 114 of the wristwatch body 100. Thus, when each of the organic EL display sheets 210 to 214 is attached to the corresponding surface of the wristwatch body 100, a gap corresponding to the thickness of the organic EL display sheet may be formed between the adjacent organic EL display sheets at the corners of the wristwatch body 100.

[0048] FIG. 5 is a diagram shown for explaining the countermeasure against the gap generated between adjacent organic EL display sheets. FIG. 5 is a diagram showing, as an example, the gap generated between the upper surface organic EL display sheet 210 and the third side surface organic EL display sheet 213.

[0049] As shown in Fig. 5, at the corners of the watch body 100, a black member 280 is embedded between adjacent organic EL display sheets (in this case, between the top surface organic EL display sheet 210 and the third side surface organic EL display sheet 213). Note that, as the black member, for example, silicone rubber or the like colored black can be used. By filling the gap between adjacent organic EL display sheets with the black member 280 in this way, the gap between adjacent organic EL display sheets becomes less noticeable, and the appearance of the watch 1 becomes neat and aesthetically pleasing.

[0050] In Fig. 5, only the area between the top surface organic EL display sheet 210 and the third side surface organic EL display sheet 213 is shown. However, the gaps between the five display parts 210 to 214, that is, between the first side surface organic EL display sheet 211 and the second side surface organic EL display sheet 212, between the second side surface organic EL display sheet 212 and the third side surface organic EL display sheet 213, between the third side surface organic EL display sheet 213 and the fourth side surface organic EL display sheet 214, between the fourth side surface organic EL display sheet 214 and the first side surface organic EL display sheet 211, and between the top surface organic EL display sheet 210 and each side surface organic EL display sheet 211 to 214 are also filled with the black member 280 in the same way.

[0051] As a result, the black member 280 is embedded at the corners of the watch body 100, that is, between adjacent organic EL display sheets. And on the surfaces of the respective organic EL display sheets 210 to 214 in the state where the black member 280 is embedded between adjacent organic EL display sheets, a protective member 290 (see Fig. 6) is applied and cured so as to cover the entire surfaces of the respective organic EL display sheets 210 to 214.

[0052] FIG. 6 shows a state in which the protective member 290 is applied and cured so as to cover the entire wristwatch 1. Note that FIG. 6 is a cross-sectional view taken along the line a-a in FIG. 2(a), and components such as the display control unit 450 existing inside the wristwatch body 100 (see the functional block diagram in FIG. 4) are not shown. As shown in FIG. 6, a transparent protective member 290 is applied and cured so as to cover the five display units of the wristwatch 1, that is, the entire upper surface organic EL display sheet 210 and the first side surface organic EL display sheets 211 to 214.

[0053] Here, as the protective member 290, a silicone resin having waterproofness, corrosion resistance, and heat resistance can be preferably used. Thus, since the transparent protective member 290 is applied and cured so as to cover the five display units of the wristwatch 1, that is, the entire upper surface organic EL display sheet 210 and the first side surface organic EL display sheets 211 to 214, it has waterproofness, corrosion resistance, and heat resistance, and is also difficult to be damaged, so that a highly reliable wristwatch can be obtained.

[0054] Next, a specific display mode of the wristwatch 1 according to the embodiment will be described. The wristwatch 1 according to the embodiment can be worn on either the left or right wrist of the user. Here, as shown in FIG. 1, the case where the wristwatch 1 according to the embodiment is worn on the wrist of the user's left arm will be described.

[0055] [First Display Mode] The first display mode will be described. Assume that the user selects an analog clock display from the display image selection unit 410. As a result, the five display units 210 to 214 perform display in an analog clock display mode in which time is displayed by a plurality of hands, and the current time is displayed on the five display units 210 to 214 of the wristwatch 1. Here, the "plurality of hands" can be exemplified by an hour hand, a minute hand, and a second hand, but in the first display mode, the case where time is displayed by the hour hand and the minute hand will be described.

[0056] For example, as shown in FIG. 2, assume that the current time displayed is 1:43. In the first display mode, the hour hand 230 points between the numerical values "1" and "2" representing the time on the upper display portion 210, and the minute hand 240 extends from the upper display portion 210 to the fourth side display portion 214. Specifically, the hour hand remains on the display on the upper display portion 210, but the minute hand 240 passes between "8" and "9" on the upper display portion 210, bends at the corner P1 formed by the upper display portion 210 and the fourth side display portion 214, and extends to the fourth side display portion 214.

[0057] Here, the hand that extends and is displayed from the upper display portion 210 to the fourth side display portion 214 may be either the hour hand 230 or the minute hand 240, but it is preferable to extend and display the longer one of the hands from the upper display portion 210 to the fourth side display portion 214. When comparing the length of the hour hand and the length of the minute hand, generally, the minute hand is longer than the hour hand. For this reason, here, the hand that extends and is displayed from the upper display portion 210 to the fourth side display portion 214 is the minute hand.

[0058] In addition, in FIG. 2, the numerical values "1" to "12" representing the time are displayed on the upper display portion 210, and since the hour hand 230 is displayed on the upper display portion 210, the time in time units can be intuitively known from the position of the hour hand 230. On the other hand, the minute hand 240 is displayed so as to extend from the upper display portion 210 to the fourth side display portion 214. For this reason, it is not easy to accurately know the time in minutes from the tip Pe of the minute hand 240. In order to make it easy to understand which position the tip Pe of the minute hand 240 is pointing to, it is preferable to display some kind of mark (for example, a round mark M) at a position corresponding to the numbers "1" to "12" displayed on the upper display portion 210 on each side display portion 211 to 214 (see FIG. 2). By displaying such a round mark M, it becomes easier to read the time in minutes at the current time from the position pointed to by the tip Pe of the minute hand 240.

[0059] The display control for causing the hour hand 230 and the minute hand 240 to be displayed in this manner is performed by the display control unit 450. That is, in the wristwatch 1 according to the embodiment, the display control unit 450 causes the minute hand 240 to extend from the upper display unit 210 to one of the side display units 211 to 214, and the minute hand 241 displayed on the upper display unit 210 and the minute hand 242 displayed on at least one of the four sides to rotate in conjunction. Thus, the display control unit 450 controls the displays of the five display units 210 to 214, that is, the respective displays of the organic EL display sheets 210 to 214.

[0060] In this case, the specific display control of the minute hand 240 is such that the minute hand 241 displayed on the upper display unit 210, that is, the minute hand 241 (referred to as the upper display minute hand 241) displayed between the rotation axis portion Po and the corner portion P1, and the minute hand displayed on the fourth side display unit 214, that is, the minute hand 242 (referred to as the side display minute hand 242) displayed between the corner portion P1 and the tip portion Pe of the minute hand 240, rotate in conjunction. Based on the synchronization signal from the synchronization signal generation unit 430, the drive circuit 510 of the upper surface organic EL display sheet 210 and the drive circuit 514 of the fourth side organic EL display sheet 214 are controlled. On the other hand, for the display control of the hour hand 230, the drive circuit 510 of the upper surface organic EL display sheet 210 is driven so that the hour hand 230 rotates around the rotation axis portion Po on the upper display unit 210.

[0061] Here, the case where the minute hand 240 is displayed on the fourth side display unit 214 has been described. However, as the time changes moment by moment, the upper display minute hand 241 is displayed so as to rotate in the so-called clockwise direction on the upper surface organic EL display sheet 210, and the side display minute hand 242 is displayed so as to rotate in the so-called clockwise direction on the side display units 211 to 214 in conjunction with the upper display minute hand 241.

[0062] Since the upper display section 210 formed on the watch body 100 is not circular, in order to extend and display the minute hand 240 across each of the side display sections 211 to 214, it is necessary to vary the length of the minute hand 240 (the length from the rotation axis portion Po to the corner portion P1) according to the position of the minute hand 240. For example, when the minute hand 240 is positioned at "9" on the fourth side display section 214 and when it is positioned at "11", it is necessary to perform display control so as to vary the length of the upper display minute hand 241.

[0063] Such display control is performed by previously setting the length of the upper display minute hand 241 according to the position of the minute hand 240, and in the display control section 450, the upper display minute hand 241 is displayed based on the length of the upper display minute hand 241 set according to the position of the minute hand 240. By the display control section 450 performing such display control, regardless of the position of the minute hand 240 on the upper display section 210, it is possible to display the portion from the rotation axis portion Po to the tip portion Pe as a single minute hand.

[0064] In this way, in the first display mode, not only are the hour hand 230 and the minute hand 240 displayed on the upper display section 210, but the minute hand 240 is also displayed in a state of extending from the upper display section 210 to one of the side display sections 211 to 214. In this way, since the wristwatch 1 according to the embodiment can perform a display like the first display mode, it becomes a wristwatch with an unprecedented new value.

[0065] [First Modification Example of the First Display Mode] In the above-described first display mode, the numbers from "1" to "12" representing time are exemplified for display on the upper display unit 210. However, as shown in FIG. 7, they may be displayed on each of the side display units 211 to 214. That is, the display control unit 450 causes the first side display unit 211 to display "11", "12", and "1", the second side display unit 212 to display "2", "3", and "4", the third side display unit 213 to display "5", "6", and "7", and the fourth side display unit 214 to display "8", "9", and "10", and controls the drive circuits of the respective organic EL display sheets 211 to 214 accordingly. In this case, it is preferable to display a round mark M at a position corresponding to the numbers from "1" to "12" displayed on each of the side display units 211 to 214 on the upper display unit 210.

[0066] Also, the hour hand 230 is displayed on the upper display unit 210 in the same manner as in the first display mode shown in FIG. 2, and the minute hand 240 is displayed so as to extend across one of the side display units 211 to 214. Note that the numbers from "1" to "12" may be displayed on both the upper display unit 210 and each of the side display units.

[0067] By performing the display according to the first modification of the first display mode, the wristwatch 1 according to the embodiment also becomes a wristwatch having a novel value not found in the prior art.

[0068] [Second Display Mode] FIG. 8 is a diagram shown for explaining the second display mode of the wristwatch 1 according to the embodiment. The second display mode of the wristwatch 1 according to the embodiment is also a case where the five display units 210 to 214 are set to the analog clock display mode, similar to the first display mode described above. In the second display mode, similar to the first modification example 1 (see FIG. 7) of the first display mode, the numerical values from "1" to "12" representing the time are to be displayed on the respective side surface organic EL display sheets 211 to 214. Further, in the second display mode of the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that, as seen from the user, it seems as if the inside of the wristwatch body 100 is visible through, and the time display in the analog clock display mode is displayed correctly left and right on the third side surface display unit 213 and the fourth side surface display unit 214 of the wristwatch body 100, and is displayed reversed left and right on the first side surface display unit 211 and the second side surface display unit 212.

[0069] Here, controlling the display of each of the organic EL display sheets 210 to 214 so that the inside of the wristwatch body 100 is visible through means controlling the display as if the wristwatch body 100 were a transparent container. Specifically, it means controlling the display so that the user can visually observe the side surfaces inside the wristwatch body 100 (the side surface 111a inside the first side surface 111 and the side surface 112a inside the second side surface 112), and the inside bottom surface 115a of the wristwatch body 100 is visible to the user. Note that the "transparent container" in this case may be a colorless transparent container or a colored transparent container having light transmissivity.

[0070] By performing such display control, it appears to the user as if the inside of the watch body 100 is visible through. That is, it appears as if the watch body 100 is a transparent container. In particular, the numbers "11", "12", "1" and "1", "3", "4" displayed on the first side display portion 211 and the second side display portion 212 that are not originally visible to the user are displayed with the individual numbers reversed left and right as seen by the user. Therefore, the user will have the feeling as if the watch body 100 is a transparent container and the inside of the watch body 100 is visible through.

[0071] Also, in the second display mode, the hour hand 230 and the minute hand 240 are displayed on the upper surface display portion 210 that appears transparent as seen by the user. Although the minute hand 240 is shown as being displayed only on the upper surface display portion 210 in this case, similar to the first display mode, it may be extended and displayed across one of the side display portions 211 to 214.

[0072] In this way, in the second display mode, it appears to the user as if the inside of the watch body 100 is visible through, and the numerical display representing the time in the analog clock display mode is displayed with the correct left - right orientation on the third side display portion 213 and the fourth side display portion 214, and with the reversed left - right orientation in the area corresponding to the first side display portion 211 and the second side display portion 212 on the upper surface display portion 210. Therefore, the watch 1 according to the embodiment is a watch with a novel value that has never existed before. Since the first side display portion 211 and the second side display portion 212 are not visible to the user, it may not display the numerical values representing the time and other displays in the analog clock display mode. However, in order not to give a sense of discomfort when a person other than the user views the watch, the numerical display representing the time may be displayed with the correct left - right orientation in the same way as in the case of the third side display portion 213 and the fourth side display portion 214.

[0073] [Third Display Mode] FIG. 9 is a diagram showing a third display mode of the wristwatch 1 according to the embodiment. The third display mode of the wristwatch 1 according to the embodiment is also a case where the five display units 210 to 214 are in the analog clock display mode, similar to the first display mode and the second display mode described above.

[0074] Also in the third display mode of the wristwatch 1 according to the embodiment, similar to the second display mode, the display control unit 450 performs display control such that it seems as if the inside of the watch body 100 is visible through, that is, display control as if the watch body 100 is a transparent container when viewed by the user. However, in the third display mode, the display control unit 450 performs display control so that the hour hand 230 and the minute hand 240 rotate while being located inside the watch body 100.

[0075] Here, the display control for making it seem as if the inside of the watch body 100 is visible through when viewed by the user during use is, similar to the second display mode, realized by performing display control such that the user can visually see the side surfaces inside the watch body 100 (the side surface 111a inside the first side surface 111 and the side surface 112a inside the second side surface 112), and the inner bottom surface 115a of the watch body 100 is visible when viewed by the user. At this time, similar to the second display mode, the "11", "12", "1" and "1", "3", "4" displayed on the first side surface display unit 211 and the second side surface display unit 212 that are not originally visible to the user are display-controlled so that the individual numbers are displayed in reverse left and right when viewed by the user.

[0076] In addition, the third display mode is to display such that the inside of the watch body 100 is visible through, and to display the hour hand 230 and the minute hand 240 rotating while being located inside the watch body 100. Here, to display the hour hand 230 and the minute hand 240 rotating while being located inside the watch body 100 means that the rotation axis portion Po of the hour hand 230 and the minute hand 240 exists at a substantially intermediate position in the thickness t direction of the watch body 100, and the hour hand 230 and the minute hand 240 are displayed so as to fit inside the watch body 100, and then the hour hand 230 and the minute hand 240 are displayed so as to rotate.

[0077] By the display control unit 450 performing such display control, similar to the above-described second display mode, from the perspective of the user, the inner side surface 111a of the first side surface 111 inside the watch body 100 and the inner side surface 112a of the second side surface 112 can be visually observed, and the inner bottom surface 115a of the watch body 100 can be visually observed. Further, in the third display mode, from the user's perspective, the hour hand 230 and the minute hand 240 appear to rotate while being located inside the watch body 100.

[0078] In this way, in the third display mode, from the user's perspective, it seems as if the inside of the watch body is transparent and the hour hand and the minute hand appear to rotate while being located inside the watch body. Therefore, the watch 1 according to the embodiment is a watch with a novel value that has never existed before.

[0079] [Fourth Display Mode] FIG. 10 is a diagram shown for explaining the fourth display mode in the watch 1 according to the embodiment. In the above-described first to third display modes, each display mode when the five display units 210 to 214 are set to the analog clock display mode has been described. The fourth display mode is the case when the five display units 210 to 214 are set to the digital clock display mode. Here, the digital clock display mode is defined as a display mode in which the time is not represented by the hour hand and the minute hand but by numerical values. Also, in the fourth display mode, not only the time but also the date, day of the week, and other information are to be displayed. To perform such display, the user can set the five display units 210 to 214 to the digital clock display mode, for example, by selecting "Digital Clock Display" from the display image selection screen that functions as the display image selection unit 410.

[0080] By setting the five display units 210 to 214 to the digital clock display mode, for example, as shown in FIG. 10, on the upper surface display unit 210, in addition to displaying the current time such as 10:25:34 as "10:25:34", the date of today such as October 1, 2020 is displayed as "20.10.01", and the day of the week of today is displayed as "Thursday". Further, as other information, for example, the weather forecast for today is displayed on each side surface display unit 211 to 214 (the fourth side surface display unit 214 in the example of FIG. 10) by a weather mark or the like. Note that these various types of information can also be displayed so as to flow on each display unit. As an example, it is also possible to display the day of the week so as to flow and then successively display various types of information following the day of the week.

[0081] As described above, in the fourth display mode, various types of information including the digital clock display can be displayed as images using the five display units 211 to 214, and some of the information (images) or all of the information (images) can be displayed so as to flow. Therefore, the wristwatch 1 according to the embodiment can be a wristwatch having a novel value that has never existed before.

[0082] [Fifth Display Mode] In the first to fourth display modes described above, the case where the five display units 210 to 214 are used as the clock display mode (analog time display mode or digital clock display mode) has been described. However, the wristwatch 1 according to the embodiment can be set to various display modes other than the clock display mode. In the fifth display mode, the case where a display mode other than the time display mode (referred to as other display mode) is set will be described.

[0083] FIG. 11 is a diagram showing the fifth display mode of the wristwatch 1 according to the embodiment. As shown in FIG. 11, the fifth display mode is a display in which, as seen from the user, it appears as if a liquid is contained in a transparent container and the liquid repeatedly increases and decreases within the transparent container. To make such a display, the user selects, for example, "Other Display Modes" from the display image selection screen that functions as the display image selection unit 410, and further selects, for example, "Pattern 1" from among a plurality of options within "Other Display Modes". Thereby, in the wristwatch 1 according to the embodiment, the display according to the fifth display mode as shown in FIG. 11 is made.

[0084] In the fifth display mode, as seen from the user, it appears as if the wristwatch body 100 looks like a transparent container and there is a liquid (shown in gray) contained in the transparent container. And the liquid contained in the transparent container performs an operation such as repeatedly increasing and decreasing while swaying within the transparent container. By the liquid performing such an operation within the transparent container, the user can feel enjoyment and wonder just by watching the movement of the liquid, and it becomes something that does not get boring. Note that display control may be performed such that the color of the liquid gradually changes.

[0085] As described above, in the fifth display mode, a display is made in which, as seen from the user, it appears as if a liquid is contained in a transparent container and the liquid repeatedly increases and decreases within the transparent container. Therefore, although the wristwatch 1 according to the embodiment is originally a wristwatch, it can also display other than the time, so it becomes a wristwatch with a novel value that has never existed before.

[0086] [Sixth Display Mode] FIG. 12 is a diagram shown to explain the sixth display mode in the wristwatch 1 according to the embodiment. Similar to the fifth display mode, the sixth display mode is a display mode when various display modes other than the time display mode are set. In this case, assume that the user selects, for example, "Other Display Modes" from the display image selection screen that functions as the display image selection unit 410, and further selects, for example, "Pattern 2" from among a plurality of options in "Other Display Modes". As a result, it is assumed that the display as shown in FIG. 12 is started.

[0087] As shown in FIG. 12, in the sixth display mode, a lattice pattern is displayed on the five display units 210 to 214. Then, as shown in FIGS. 12(a) and 12(b), a display is performed to change the size of the squares formed by the lattice. At this time, the change in the size of the squares may be continuously and gradually changed, or may be changed stepwise as large, medium, and small. Also, the entire lattice pattern may be displayed, for example, so as to move in the direction from right to left in the drawing.

[0088] As described above, in the sixth display mode, since a predetermined pattern can be displayed on the entire five display surfaces, and the size of the pattern can be changed and displayed while scrolling, the wristwatch 1 according to the embodiment can display not only the time but also other displays although it is originally a wristwatch, so that it becomes a wristwatch with a novel value not found in the prior art. The wristwatch 1 according to the embodiment becomes a wristwatch with a novel value not found in the prior art.

[0089] [Seventh Display Mode] FIG. 13 is a diagram shown to explain the seventh display mode of the wristwatch 1 according to the embodiment. Similar to the fifth and sixth display modes, the seventh display mode is a display mode when various display modes other than the time display mode are set. In this case, assume that the user selects, for example, "Other Display Modes" from the display image selection screen that functions as the display image selection unit 410, and further selects, for example, "Pattern 3" from among a plurality of options in "Other Display Modes". As a result, it is assumed that the display as shown in FIG. 13 is started.

[0090] In the seventh display mode, as shown in FIG. 13, it is displayed as if a pattern like a number of polka dots flows through the five display units 210 to 214 when viewed by the user. In this case, for example, a number of polka dots are generated so as to gush out at the third side display unit 213, and the generated individual polka dots are gradually enlarged and grow while flowing through the upper surface display unit 210, the fourth side display unit 214, the second side display unit 212, and the first side display unit 211 for display control. The user can feel fun and wonder just by watching the movement of the polka dots, and will not get bored. Note that display control such as changing the color of each polka dot or changing the color as it grows may be performed.

[0091] As described above, in the seventh display mode, since it is possible to display a pattern like a polka dot on the entire five display units and display it so as to flow while changing the size or color of the pattern, the wristwatch 1 according to the embodiment can display not only the time but also other displays while being a wristwatch. Therefore, it becomes a wristwatch with a novel value that has never existed before.

[0092] [Eighth Display Mode] FIG. 14 is a diagram shown to explain the eighth display mode of the wristwatch 1 according to the embodiment. The eighth display mode is also a display mode when various display modes other than the time display mode are set, similar to the fifth display mode to the seventh display mode. In this case, assume that the user selects, for example, "Other Display Modes" from the display image selection screen that functions as the display image selection unit 410, and further selects, for example, "Pattern 4" from among a plurality of options in "Other Display Modes". As a result, it is assumed that the display as shown in FIG. 13 is started.

[0093] The eighth display mode is to perform display control so that, as shown in FIG. 14, the rectangular parallelepiped wristwatch 1 appears to be divided into a plurality of blocks when viewed by the user. For example, after displaying the rectangular parallelepiped wristwatch 1 as if it were divided into four blocks as shown in FIG. 14, the four blocks are each further displayed as being subdivided, and then the display control is performed so as to return to the original state (the state before division). In this case, display control such as changing the color of each block or changing the color for each predetermined region may be performed.

[0094] As described above, in the eighth display mode, since it is possible to display the rectangular parallelepiped wristwatch 1 as if it were divided into a plurality of blocks when viewed by the user, the wristwatch 1 according to the embodiment can display not only the time but also other displays while being originally a wristwatch. Therefore, it becomes a wristwatch with a novel value that has never existed before.

[0095] [Ninth Display Mode] FIG. 15 is a diagram shown for explaining the ninth display mode of the wristwatch 1 according to the embodiment. The ninth display mode is also a display mode when various display modes other than the time display mode are set, similar to the fifth display mode to the eighth display mode. However, the fifth display mode to the eighth display mode were display modes for displaying patterns, while the ninth display mode is a case where it is a display mode for displaying a composite image on the wristwatch 1 according to the embodiment. Here, a composite image means that various images such as a time scale image, a calendar image for each month, and a photograph are displayed so as to be linked or related to the five display units 210 to 214. In this case, the user selects, for example, "composite" from the display image selection screen. As a result, the display as shown in FIG. 15 is made. In this case, since various images can be displayed not only on the upper surface display unit 210 of the wristwatch 1 but also on each side surface display units 211 to 214, various composite images can be displayed.

[0096] As described above, in the ninth display mode, since various composite images can be displayed using the entire five display units, the wristwatch 1 according to the embodiment can display not only the time but also other information while being originally a wristwatch, thus becoming a wristwatch with unprecedented new value.

[0097] As described above, as the display modes of the wristwatch 1 according to the embodiment, the first to ninth display modes have been described, but these are merely examples, and various displays can be performed. For example, it is also possible to perform a display such as regarding the rectangular parallelepiped-shaped wristwatch 1 as an aquarium and making fish swim, or to display in a fast-forward manner the process of a stylized flower blooming from a bud state.

[0098] As described above, according to the wristwatch 1 according to the embodiment, it is possible to display images in various modes on the five display units 210 to 214 (the upper surface display unit 210 and the side surface display units 211 to 214) of the rectangular parallelepiped wristwatch body 100. Further, when displaying images on the five display units 210 to 214, the display of each of the five display units is controlled so that the images to be displayed on each of the five display units 210 to 214 are linked or related to each other. Therefore, various uses can be given to the wristwatch 1, and it is possible to provide a wristwatch with unprecedented new value.

[0099] It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. For example, the following modifications can also be made.

[0100] (1) In the above embodiment, in the display modes (the first to third display modes) in which the five display units 210 to 214 are in the analog clock display mode, the second hand was not mentioned, but it is also possible to display the second hand in addition to the hour hand and the minute hand.

[0101] That is, in the case of the analog clock display mode in which time is displayed by a plurality of hands, when at least the longest hand among the plurality of hands extends from the upper surface display unit 210 to one of the four side surface display units (each side surface display unit 211 to 214), and the portion displayed on the upper surface display unit 210 and the portion displayed on one side surface display unit among the portions of the hand extending over one side surface display unit rotate in conjunction with each other, the display of each of the five display units is controlled.

[0102] Here, when the plurality of hands are the hour hand and the minute hand, generally, since the minute hand is longer than the hour hand, as described in the first display mode above, the minute hand 230 is displayed so as to extend from the upper surface display unit 210 to one of the side surface display units 211 to 214.

[0103] Also, when the plurality of hands are the hour hand, the minute hand, and the second hand, and the length of each hand is such that the hour hand < the minute hand < the second hand (here, "<" represents an inequality sign), only the second hand is displayed so as to extend from the upper surface display unit 210 to one of the side surface display units 211 to 214. Note that, as described above, since it is set as "at least the longest hand" among the plurality of hands, not only the longest second hand but also the second-longest minute hand may be displayed so as to extend from the upper surface display unit 210 to one of the side surface display units 211 to 214.

[0104] Also, when the plurality of hands are the hour hand, the minute hand, and the second hand, and the length of each hand is such that the hour hand < the second hand < the minute hand, only the minute hand is displayed so as to extend from the upper surface display unit 210 to one of the side surface display units 211 to 214. Also in this case, since it is set as "at least the longest hand" among the plurality of hands, not only the longest minute hand but also the second-longest second hand may be displayed so as to extend from the upper surface display unit 210 to one of the side surface display units 211 to 214.

[0105] Also, when the plurality of hands are the hour hand, minute hand, and second hand, if the lengths of the respective hands are such that the hour hand < the minute hand = the second hand, the minute hand and the second hand are displayed so as to extend from the upper display unit 210 to one of the side display units 211 to 214. By doing so, the "at least the longest hand" is displayed so as to extend from the upper display unit 210 to one of the side display units 211 to 214.

[0106] (2) In each display mode in the above embodiment, the case where some display (analog clock display, digital clock display, and various pattern displays) is performed on the five display units 210 to 214 of the wristwatch 1 has been described. However, it is also possible to set a non-display mode in which nothing is displayed on the five display units 210 to 214. In this non-display mode, there is no pattern over the entire area of the five display units. By enabling the setting of the non-display mode in this way, it becomes a wristwatch that, although it is a wristwatch, does not make the wearer aware of the presence of time display in the non-display mode, and a new value can be given to the wristwatch.

[0107] (3) In each display mode in the above embodiment, the color of the display content has not been mentioned, but of course, so-called color display is possible. For example, when performing an analog clock display, it is also possible to display the hour hand and the minute hand in different colors, or to display them so that the color changes at the exact hour such as 1 o'clock and 2 o'clock.

[0108] (4) In the above embodiment, the case where the five display units 210 to 214 are composed of five organic EL display sheets (the upper organic EL display sheet 210, the first side organic EL display sheet 211, the second side organic EL display sheet 212, the third side organic EL display sheet 213, the fourth side organic EL display sheet 214) has been exemplified. However, the five display units 210 to 214 may be composed of one organic EL display sheet.

[0109] FIG. 16 is a diagram showing a case where the five display units 210 to 214 are formed of a single organic EL display sheet. When the five display units 210 to 214 are formed of a single organic EL display sheet, the organic EL display sheet is formed into a shape as shown in FIG. 16. In this case, a single organic EL display sheet has a shape in which the top surface organic EL display sheet 210 existing in the center extends in four directions to the first side surface organic EL display sheet 211, the second side surface organic EL display sheet 212, the third side surface organic EL display sheet 213, and the fourth side surface organic EL display sheet 214. A single organic EL display sheet having such a shape is bent along the broken line shown in FIG. 16 so as to follow the outer shape of the watch body 100 (see FIG. 3(a).) and attached to the watch body 100.

[0110] Thereby, the same configuration as that of the watch 1 according to the above embodiment can be achieved. Note that when the five display units 210 to 214 are formed of a single organic EL display sheet, no gap is formed in the bent portion (the portion indicated by the broken line in FIG. 16). Therefore, it is not necessary to fill the bent portion with the black member described in FIG. 5. On the other hand, since a gap corresponding to the thickness of the organic EL display sheet may be formed at the corner portion of each side surface display unit, it is preferable to fill the gap with a black member. That is, in the single organic EL display sheet shown in FIG. 16, between the first side surface organic EL display sheet 211 and the second side surface organic EL display sheet 212, between the second side surface organic EL display sheet 212 and the third side surface organic EL display sheet 213, between the third side surface organic EL display sheet 213 and the fourth side surface organic EL display sheet 214, and between the fourth side surface organic EL display sheet 214 and the first side surface organic EL display sheet 211, since a gap corresponding to the thickness of the organic EL display sheet may be formed, it is preferable to fill the gap with a black member.

[0111] In addition, when the five display units 210 to 214 are formed of a single organic EL display sheet, it becomes easy to interlock or associate the images displayed on the upper surface and each side surface, and the driving of the organic EL display sheet can be simplified. Therefore, since the supply of power and the supply of electrical signals from the wristwatch body 100 side to the organic EL display sheet side may be performed for a single organic EL display sheet, electrode groups may be provided at corresponding single locations on the wristwatch body 100 side and the single organic EL display sheet side, respectively.

[0112] (5) In the above embodiment, the case where the user views the wristwatch 1 with the elbow of the arm slightly bent toward the user's body (abdomen or chest side) has been described. However, there may be a case where the user bends the arm more strongly to view the wristwatch 1. FIG. 17 is a diagram shown to explain the case where the user bends the arm more strongly to view the wristwatch 1 in the second display mode of the wristwatch 1 according to the embodiment.

[0113] In the second display form (see FIG. 8) described in the above embodiment, the display control unit 450 controls the display of the third side surface display unit 213 and the fourth side surface display unit 214 so that the time display in the analog clock display mode is displayed correctly left and right on the third side surface display unit 213 and the fourth side surface display unit 214, and controls the display of the upper surface display unit 210 so that it appears to be displayed in reverse left and right on the first side surface display unit 211 and the second side surface display unit 212 as viewed by the user. This is because, as viewed by the user, the third side surface display unit 213 and the fourth side surface display unit 214 are located at positions that come into the user's view.

[0114] However, when the user bends the arm more strongly to view the wristwatch 1, as shown in FIG. 17, the second side display portion 212 and the third side display portion 213 will come into the user's view. Therefore, in this case, the display control unit 450 preferably controls the display of the second side display portion 212 and the third side display portion 213 so that they are correctly displayed horizontally, and controls the display of the upper surface display portion 210 so that it appears to be reversely displayed horizontally as seen from the user, as if on the first side display portion 211 and the fourth side display portion 214.

[0115] (6) In the above-described embodiment, the first to ninth display modes have been described, but displays in other display modes are also possible.

[0116] [Tenth Display Mode] FIG. 18 is a diagram shown for explaining another display mode (tenth display mode) of the wristwatch 1 according to the embodiment. The tenth display mode is a display mode similar to the fifth display mode (see FIG. 11), but as shown in FIG. 18, it appears as if the liquid 250 is contained in the wristwatch 1 as seen from the user, and moreover, the liquid 250 appears to be shaking, and further, the current time 252 is displayed on the upper surface display portion 210. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display portions 210 to 214 so that the above-described display mode is possible.

[0117] [Eleventh Display Mode] FIG. 19 is a diagram shown for explaining another display mode (eleventh display mode) of the wristwatch 1 according to the embodiment. The eleventh display mode is a display mode in which, as shown in FIG. 19, a state where the ribbon 254 is wound around the wristwatch 1 is displayed. In the eleventh display mode, a state where the ribbon 254 is wound or the wound ribbon 254 is unwound as time passes may be displayed. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display portions 210 to 214 so that the above-described display mode is possible.

[0118] [12th Display Mode] FIG. 20 is a diagram showing another display mode (12th display mode) of the wristwatch 1 according to the embodiment. As shown in FIG. 20, the 12th display mode is a display mode in which, in addition to the display in the 11th display mode, the current time 252 is displayed on the upper surface display unit 210. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above-described display mode is possible.

[0119] [13th Display Mode] FIG. 21 is a diagram showing another display mode (13th display mode) of the wristwatch 1 according to the embodiment. As shown in FIG. 21, the 13th display mode is a display mode in which the state of fine particles 256 seeping from the upper surface to the bottom surface of the wristwatch 1 is displayed. In the 13th display mode, the display mode may be such that the color of the surface changes periodically and fine particles of another color seep in. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above-described display mode is possible.

[0120] [14th Display Mode] FIG. 22 is a diagram showing another display mode (14th display mode) of the wristwatch 1 according to the embodiment. As shown in FIG. 22, the 14th display mode is a display mode in which a plurality of images 258 constituting the frame of the video are displayed as if they are deposited from the current (upper surface) to the past (bottom surface). As time passes, an older image among the plurality of images 258 is displayed on the upper surface display unit 210. In addition, end faces 260 of the plurality of deposited images 258 are displayed on the four side surface display units 211 to 214. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above-described display mode is possible.

[0121] [15th Display Mode] FIG. 23 is a diagram shown to explain another display mode (15th display mode) of the wristwatch 1 according to the embodiment. As shown in FIG. 23, in the 15th display mode, in the initial state, a state where small balls 262 are dispersed and randomly moving in a rectangular parallelepiped is displayed, and then, as time passes, a state where the small balls 262 gather on the upper surface and the current time 252 appears is displayed. The small balls 262 may move, for example, according to the passage of time or according to the movement of the hand. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above-described display mode is possible.

[0122] [16th Display Mode] FIGS. 24 and 25 are diagrams shown to explain another display mode (16th display mode) of the wristwatch 1 according to the embodiment. As shown in FIGS. 24 and 25, in the initial state, the current time 252 is displayed on the upper surface display unit 210. However, for example, when an acceleration is applied to the wristwatch due to the movement of the arm, based on this, a display mode in which the current time 252 moves in a bouncy manner and protrudes to the side surface is shown. FIG. 25 shows a series of movements in which the current time protrudes to one or more of the side surface display units 211 to 214 in addition to the upper surface display unit 210. As shown in FIG. 25, the four digits constituting the current time change their display mode from a to h in FIG. 25 while protruding not only to the upper surface display unit 210 but also to the four side surfaces. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above-described display mode is possible.

[0123] [17th Display Mode] FIG. 26 is a diagram showing another display mode (17th display mode) of the wristwatch 1 according to the embodiment. As shown in FIG. 26, in the 17th display mode, the current time 252 is displayed on the upper surface display unit 210 as the initial state. However, for example, when an acceleration is applied to the wristwatch due to the movement of the arm, a display mode (an optical illusion display mode) in which the virtual wristwatch frame 264 seems to vibrate smoothly inside the wristwatch 1 is triggered by the movement. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above display mode is possible.

[0124] [18th display mode] FIG. 27 is a diagram showing another display mode (18th display mode) of the wristwatch 1 according to the embodiment. As shown in FIG. 27, in the 18th display mode, flows with different flow directions 266 are generated for each display surface (the upper surface display unit 210 and the four side surface display units 211 to 214), and the flow changes as shown in the upper and lower diagrams of FIG. 27, for example, every second. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above display mode is possible.

[0125] [19th display mode] FIG. 28 is a diagram showing another display mode (19th display mode) of the wristwatch 1 according to the embodiment. As shown in FIG. 28, the 19th display mode is a display mode in which a pattern 268 representing a pressure change on the time axis is displayed on the side display portions 211 to 214. As shown in the upper diagram of FIG. 28, the 19th display mode may be a display mode as a so-called heart rate monitor in which a pattern representing the user's heart rate moves, for example, counterclockwise on the four side display portions 211 to 214 and the upper surface display portion 210 as the pattern 268 representing the pressure change on the time axis. Further, as shown in the lower diagram of FIG. 28, as the pattern 268 representing the pressure change on the time axis, a pattern representing the sound pressure of the music being played moves, for example, counterclockwise on the four side display portions 211 to 214, and information regarding the music being played and an icon 270 for operating a player related to music playback are displayed on the upper surface display portion 210. It may be a display mode that displays as a so-called music visualizer. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display portions 210 to 214 so that the above-described display mode is possible.

[0126] [20th display mode] FIG. 29 and FIG. 30 are diagrams shown for explaining another display mode (20th display mode) of the wristwatch 1 according to the embodiment. The 20th display mode is a display mode in which the display is switched by a swipe operation. For example, as shown in the upper diagram of FIG. 29, as an initial state, a first image G1 is displayed on four display units, i.e., the upper surface display unit 210, the first side surface display unit 211, the second side surface display unit 212, and the third side surface display unit 213, and a second image G2 is displayed on the remaining fourth side surface display unit 214. Then, as shown in the lower diagram of FIG. 29, by swiping an arbitrary portion P of the boundary between the first image G1 and the second image G2 with a finger, a display is made such that the boundary between the first image G1 and the second image G2 and the boundary between the second image G2 and a third image G3 (not shown) are pulled and moved. Then, when the arbitrary portion P is further swiped with a finger and the swipe operation is ended, as shown in FIG. 30, a display mode is made such that the boundary between the first image G1 and the second image G2 and the boundary between the second image G2 and the third image G3 seem to be adsorbed and stopped by something.

[0127] Note that, as display examples in which the display is switched by a swipe operation, for example, analog / digital display switching, clock / calendar display switching, unlocking, etc. can be exemplified, but various other display switchings are also possible. In the wristwatch 1 according to the embodiment, the display control unit 450 controls the display of each of the five display units 210 to 214 so that the above-described display mode becomes possible.

[0128] Note that when realizing the 20th display mode, as the five display units 210 to 214, a touch panel in which a touch pad is disposed on the surface of each of five organic EL display sheets is used. The touch pad may be disposed on the surface of the black member 280.

[0129] (7) In the above embodiment, the case where the gap formed between the five display units 210 to 214 (between adjacent organic EL display sheets) is made inconspicuous by embedding a black member has been exemplified. However, since the organic EL display sheets are thin, there may be cases where the gap is not formed conspicuously in the adjacent portions of each organic EL display sheet. In such cases, it is not necessary to embed the black member in the adjacent portions of each organic EL display sheet. Even when the black member is not embedded, it is preferable to apply and cure the protective member so as to cover the entire display unit.

[0130] (8) In the above embodiment, the case where the five display units 210 to 214 are composed of five organic EL display sheets (see Fig. 3(b)) has been exemplified. Also, as a modification of the above embodiment, the case where the five display units 210 to 214 are composed of one organic EL display sheet (see Fig. 16) has been exemplified. However, it is not limited to this. That is, the five display units 210 to 214 may be composed of two to four organic EL display sheets. For example, as shown in Fig. 31, the five display units 210 to 214 may be composed of three organic EL display sheets. In Fig. 31, the first side display unit 211, the upper surface display unit 210, and the third side display unit 213 are formed of one connected organic EL display sheet, and the second side display unit 212 and the fourth side display unit 214 are each formed of two separated organic EL display sheets. Thus, the five display units 210 to 214 are composed of three organic EL display sheets.

[0131] Note that the example where the five display units 210 to 214 are composed of three organic EL display sheets is not limited to this. Although illustration is omitted, for example, the second side display unit 212, the upper surface display unit 210, and the fourth side display unit 214 may be formed of one connected organic EL display sheet, and the first side display unit 212 and the third side display unit 214 may each be formed of two separated organic EL display sheets. Thus, the five display units 210 to 214 are composed of three organic EL display sheets.

[0132] Also, although illustration is omitted, the five display units 210 to 214 may be composed of two organic EL display sheets. For example, it may be composed of one organic EL display sheet in which the first side display unit 211 to the fourth side display unit 214 are connected, and one organic EL display sheet in which only the upper surface display unit 210 is separated. Thus, the five display units 210 to 214 are composed of two organic EL display sheets.

[0133] Similarly, although illustration is omitted, the five display units 210 to 214 may be composed of four organic EL display sheets. For example, it may be composed of one organic EL display sheet in which the first side display unit 211 and the upper surface display unit 210 are connected, and three organic EL display sheets in which the second side display unit 212, the third side display unit 213, and the fourth side display unit 214 are each separated into one sheet. Thus, the five display units 210 to 214 are composed of four organic EL display sheets.

[0134] (9) In the above embodiment, the wristwatch has been described as having five display units, but it may not have five display units. That is, the wristwatch of the present invention may include a rectangular parallelepiped wristwatch body 100, and at least two display units formed over the entire area of each of "the upper surface on the side opposite to the lower surface facing the user's wrist during use" and "at least one of the four side surfaces" among the six surfaces constituting the surface of the wristwatch body 100, and a display control unit that controls the display of each of the at least two display units. That is, in the wristwatch 1 according to the above embodiment, the at least two display units are five display units formed over the entire area of each of the five surfaces composed of the upper surface and the four side surfaces, but it may have at least two display units instead of five display units.

[0135] FIG. 32 is a diagram showing an example in the case where the display unit 20 includes at least two display units. In FIG. 32, the display unit 200 of a wristwatch having 2 to 4 display units as at least two display units is shown in an unfolded manner. In FIG. 32, FIGS. 32(a) and 32(b) show the case of having two display units, FIGS. 32(c) to 32(f) show the case of having three display units, and FIGS. 32(g) to 32(i) show the case of having four display units. As shown in each figure of FIG. 32, in a wristwatch having 2 to 4 display units, there is a surface that does not have a display unit made of an organic EL display sheet, but a protective member may also be applied and cured on the surface that does not have a display unit made of an organic EL display sheet.

[0136] Also, as shown in each figure of FIG. 32, even in the case of having 2 to 4 display units, each display unit may be composed of a plurality of organic EL display sheets or may be composed of one organic EL display sheet. That is, FIGS. 32(a) and 32(h) show the case where each display unit is composed of two organic EL display sheets, FIGS. 32(c) and 32(e) show the case where each display unit is composed of three organic EL display sheets, and FIG. 32(g) shows the case where each display unit is composed of four organic EL display sheets. Also, FIGS. 32(b), 32(d), 32(f), and 32(i) show the case where each display unit is composed of one organic EL display sheet.

[0137] In FIGS. 31 and 32, there are cases where the upper surface display unit 210 is square, but it may be rectangular as shown in FIG. 3 and the like used in the description of the foregoing embodiments. Conversely, in the foregoing embodiments, the upper surface display unit 210 is rectangular, but the upper surface display unit 210 may be square.

[0138] (10) In the foregoing embodiments, the display unit 200 (five display units 210 to 214) is exemplified as being composed of an organic EL display sheet, but it may be composed of a micro LED (Light Emitting Diode) display sheet.

[0139] (11) In the above-described embodiments, the case where the present invention is applied to the wristwatch 1 has been described. However, not only the wristwatch but also a wristwatch-type display device can be used. Even in the case of a wristwatch-type display device, a rectangular parallelepiped wristwatch-type display device main body and, among the six surfaces constituting the surface of the wristwatch-type display device main body, "the upper surface opposite to the lower surface facing the user's wrist during use" and "at least one of the four side surfaces" are provided. And at least two display units formed over the entire area of each of them, and a display control unit that controls the display of each of the at least two display units. Further, it is preferable that the display control unit has a function of controlling the display of each of the at least two display units so that the images displayed on each of the at least two display units are linked or related. In such a wristwatch-type display device, it is preferable that the at least two display units are five display units formed over the entire area of each of the five surfaces composed of the upper surface and the four side surfaces. In such a wristwatch-type display device, the display control performed by the display control unit 450 may be set to perform display control peculiar to the wristwatch-type display device that is not particularly required for the wristwatch.

[0140] As described above, according to the wristwatch-type display device of the present invention, in addition to the upper surface of the rectangular parallelepiped wristwatch-type display device main body, the side surfaces can also be used to display various images in various modes. Therefore, according to the wristwatch-type display device of the present invention, it is possible to provide a wristwatch-type display device having a novel value that has never existed before. Even in the wristwatch-type display device of the present invention, the same modified implementation as that of the wristwatch of the present invention is possible.
