  In the techniques described in Patent Document 1 and Patent Document 2, the movement of the display (display unit) is rotational movement, linear movement, or a combination thereof. For this reason, only a relatively simple displacement state of the display is realized. However, for example, when a plurality of displays move in a coordinated manner, it is desirable that a complicated displacement state can be realized.

  An object of the present invention is to easily realize a complicated displacement state of a display.

  The display device according to the present invention includes a display, a shape memory alloy, a support unit that supports the display so as to be displaceable, and a control that controls the support state of the support unit so that the display is in a predetermined displacement state. Part.

  Further, the display displacement state control method according to the present invention is a method for controlling the displacement state of the display, wherein the display is supported by a support portion made of a shape memory alloy, and the support state of the support portion is controlled. By doing so, the displacement state of the display is changed.

  In the present invention, the display is supported in a freely displaceable manner by a support portion formed using a shape memory alloy, for example, a shape memory alloy or a shape memory resin. Therefore, if a predetermined shape is memorized in the shape memory alloy on the high temperature side, for example, the display can be easily brought into a predetermined displacement state by applying heat to the shape memory alloy.

  For example, the support unit includes a coarse adjustment unit that coarsely adjusts the displacement state of the display and a fine adjustment unit that finely adjusts the displacement state of the display, and the fine adjustment unit is configured using a shape memory alloy. The coarse adjustment unit can be constituted by, for example, an arm, a rail or the like. Although the displacement of the display by the shape memory alloy is small, a large change in the displacement state as a whole can be realized by configuring only the fine adjustment portion using the shape memory alloy.

  Further, for example, the display includes a plurality of displays, and the support unit includes a plurality of support units that respectively support the plurality of displays. In this case, since each support part is comprised using shape memory alloy, when a some display moves in cooperation, a complicated displacement state is easily realizable.

  In the case of having a plurality of displays in this way, for example, the types of images displayed on the plurality of displays are determined according to a user instruction, and the support state of the plurality of support units is controlled based on the determination result. The display is automatically displaced according to the image type. Thereby, the user can observe the image in a state where the plurality of displays are in a displacement state corresponding to the image type.

  Further, in the case of having a plurality of displays as described above, for example, the displacement state of the plurality of displays is designated by the user, and the support state of the plurality of support parts is controlled based on the designated contents, and the plurality of displays are designated. The displaced state is set. Thereby, the user can observe an image with a plurality of displays in a displacement state suitable for the image type.

  According to the present invention, the display is supported so as to be displaceable by the support portion formed using the shape memory alloy, and a complicated displacement state of the display can be easily realized. Further, according to the present invention, there are a plurality of displays as the display, and a plurality of support portions that respectively support the plurality of displays as the support portions, and each support portion is configured using a shape memory alloy. Therefore, when a plurality of displays move cooperatively, a complicated displacement state can be easily realized.
