  Hereinafter, embodiments of the present invention will be described in detail for each example.

FIG. 1 is an exploded perspective view showing the decoration device of the first embodiment.
A smartphone 12 shown in the figure is housed and used in a protective exterior 14. The exterior 14 is made of transparent plastic or the like. In FIG. 1, the smartphone 12 is illustrated with its operation surface facing down.

  The display control circuit 18 and the display device 16 are sequentially stacked on the back surface of the smartphone 12, and the whole is surrounded by the exterior 14. The exterior 14, the display device 16, and the display control circuit 18 are integrated with an adhesive or the like, and these constitute the decoration device 10.

  The display device 16 is an electronic paver in this embodiment. Currently, those that display only black and white images are widespread, but it will be more effective if those that display color images are put into practical use. The display image 46 displayed on the display device 16 is rewritten and controlled by the display control circuit 18. The electronic paver consumes power only when the display image 46 is rewritten. After rewriting, the image continues to be displayed with no power. Therefore, it is suitable for decoration of the smartphone 12.

  The display control circuit 18 receives supply of power from the smartphone 12 through the connection terminal 24 and the connector 20 when the display image 46 of the display device 16 is rewritten. The connector 20 is for connecting a connection terminal 22 provided on the smartphone 12 and a connection terminal 24 provided on the display control circuit 18 and has, for example, a USB (Universal Serial Bus) connection structure.

  The smartphone 12 functions as a power supply device and an image data communication device for the decoration device 10. For example, the image data is transferred to the display control circuit 18 through the connector 20. Alternatively, it is transmitted from the smartphone 12 to the display control circuit 18 by wireless communication.

2A is an external perspective view in which a decoration device is mounted on a smartphone, FIG. 2B is a modified example of the exterior 14, and FIG. 2C is a modified perspective view of the display control circuit 16.
As shown in FIG. 2A, the display image 46 that can be seen through the transparent exterior 14 functions as a decoration of the smartphone 12. Complex patterns and characters can be freely selected and displayed. Therefore, a unique decoration can be easily realized. Further, the display image 46 can be changed at an arbitrary timing, and the substantial cost for changing the decoration can be reduced.

  The exterior 14 is preferably made of transparent hard plastic, but may be made of, for example, opaque plastic as long as a window through which the display image 46 can be seen is provided. Further, it may be a flexible bag. For example, as illustrated in FIG. 2B, a cover-shaped exterior 14 a that is fixed to only a part of the smartphone 12 may be used.

  The display device 16 may be flat or curved. The shape may be rectangular, polygonal or circular. Moreover, as shown in FIG.2 (c), you may divide | segment into two or more parts 16a, 16b, and 16c. For example, the display device 16c may be provided on the side surface of the exterior 14, and each display device 16a, 16b, 16c may be individually controlled to rewrite the display image.

  Appropriate power is consumed for rewriting the display image. However, if the display device 16 is divided into a plurality of parts, the power consumption can be minimized by rewriting only a part of the display image. Further, there is an effect that the image data for rewriting the display image can be a small amount of data.

FIG. 3 is a circuit block diagram of the decoration device according to the second embodiment.
As shown in FIG. 3A, the decoration device 10 includes a display device 16, a display control circuit 18, and a reception circuit 26. When the display device 16 is electronic paper, the display control circuit 18 and the receiving circuit 26 are not operating in a state where image data has already been written. It is assumed that the connection terminal 24 shown in FIG. 1 and the receiving circuit 26 shown in FIG.

  Here, when rewriting the display image, the connector 20 is connected as shown in FIG. Thereby, driving power is supplied from the power supply circuit 30 of the smartphone 12 to the display control circuit 18 and the receiving circuit 26. Then, the image data for rewriting is transferred from the image data transmitting device 28 to the receiving circuit 26 through the connector 20. Thereby, the display control circuit 18 rewrites the image displayed on the display device 16 with a new image.

  Thereafter, the connector 20 is detached again, and the operations of the display control circuit 18 and the receiving circuit 26 are stopped. The display device 16 functions as a decoration device of the smartphone 12 as it is with the rewritten image displayed. The connector is detachable and may be in the form of a block or a cable.

FIG. 4 is an explanatory diagram of an actual smartphone operation method.
As shown in the figure, the operation screen 34 displayed on the operation screen of the smartphone 12 and operating the start button 32 for image rewriting is displayed to display “select deco”. On the operation screen 34, for example, an image selection button 36, a download button 38, and an image creation button 40 are provided.

  The image selection button 36 is for selecting image data stored in the storage device of the smartphone 12. The download button 38 is for downloading image data from a predetermined website. The image creation button 40 is, for example, for starting an application that manually creates image data.

  When the image selection button 36 is operated, an image selection screen 42 is displayed. A page break button 44 is provided on the image selection screen 42. Thereby, desired image data is selected. The selected image data is displayed on the image selection screen 42. When the rewrite button 48 is operated, the selected image data is transferred to the display device 16. Then, a display image 46 corresponding to the exterior 14 is displayed.

  The image data can be transferred using wired communication using a USB connector, short-range wireless communication, infrared communication, or the like. Further, a power supply device for driving the display control circuit 18 and the receiving circuit 26 can be incorporated on the exterior 14 side. A button battery or a sheet-like secondary battery can be incorporated.

  Further, if the power supply device can be incorporated into the exterior 14, the display device 16 can be replaced with a liquid crystal display plate, an organic EL substrate, or the like. In that case, the display image can be a moving image as well as a still image.

  In the above embodiment, an example of the exterior of the smartphone 12 has been shown. However, the present invention is suitable for decoration of a portable electronic device having a display image rewriting function, such as a tablet computer or a notebook computer. Also suitable. In addition to the smartphone application, the image rewriting device can use a personal computer, a computer built in equipment, or the like.

  Further, it can be used for decoration of small furniture such as a table clock. Furthermore, it can also be used for decoration of some clothing items such as bags and belt buckles. For these, as will be described later, a display device that can change colors and patterns as long as it has a power source is also suitable.

FIG. 5 shows a modification of the display device. (A) is a perspective view of a mobile phone, (b) is a perspective view of an exterior, (c) is a block diagram of a display device, and (d) is a block diagram of a power feeding circuit.
In the first embodiment, the display device that can self-hold the state after the power is cut off is illustrated. That is, the electronic paper has an effect that a power source for driving the display control circuit 18 and the receiving circuit 26 is necessary only when image data is rewritten, but a power source after data rewriting is unnecessary.

  However, there is a problem that a device that can display a color image has not yet spread. In this third embodiment, as an alternative, an electrochromic display is used for the display device. The electrochromic display is colored by an applied voltage and can retain the color even after the power is cut off. Also, different colors can be developed depending on the level of the applied voltage.

  In an electrochromic display, a place where a voltage is applied is uniformly colored on one side, and is not colored according to image data. Therefore, in this embodiment, a display device is configured by combining a plurality of electrochromic display tiles 58a.

  In the example of FIG. 5C, a total of nine tiles 58a are arranged to form a square display device. Different voltages are supplied to these tiles from the power supply circuit 50. For example, as shown in FIG. 5 (d), several types of DC voltages are taken out from the battery group 52 and the power supply voltage is supplied to each tile 58 a through the switching circuit 54. The selector switch 56 may be configured so that a combination of supply voltages can be selected.

  With the above configuration, various pattern decorations can be realized only by operating the changeover switch 56 for applying the power supply voltage. The entire surface of the exterior 14 can be changed to a desired color at an arbitrary timing. In addition, the display device can be divided into arbitrary regions in this way, and color can be generated by a combination of a plurality of colors.

FIG. 6 is a plan view showing a modification of the display device.
The electrochromic display tiles 58b, 58c, and 58d can be attached in any arrangement to the exterior of the equipment. As shown in FIG. 6A, tiles 58b may be arranged on the substrate 60 like a grid, or rectangular shapes shown in FIG. 6B may be arranged.

  It is also possible to design the shape of the electrode for applying electricity in an electrochromic display in a geometric pattern such as an animal or a flower. In the example of FIG. 6C, the electrodes are circular.

  An electrochromic display maintains a colored state for a certain period of time even if the power is turned off after a voltage is applied. Therefore, there is an effect that power consumption for display is as low as that of electronic paper. Also, if the power supply is disconnected, the color gradually disappears over time.For example, you can apply a voltage at regular intervals to restore the original color or switch to another color to change the color and design. Can be complicatedly changed.

  As described above, the display device according to the third embodiment requires neither a receiving circuit nor an image data transmitting device if the power source is integrated with the exterior of the equipment. If the display device is composed of a plurality of electrochromic display tiles and a switching circuit is provided that automatically switches the power supply voltage for coloring each tile at regular intervals, any dynamic color pattern can be used. Equipment can be decorated.
