Description

  The present invention relates to an electro-optical device and an electronic apparatus, and more particularly to a configuration of an electro-optical device and an electronic apparatus suitable for use as a display device configured to rotate a display screen to obtain a required display mode.

  2. Description of the Related Art Conventionally, a rotary type virtual display system that displays a different image in a different direction or forms a three-dimensional image by rotating a liquid crystal display having a display screen is known (for example, The following nonpatent literature 1 reference). In this type of system, the liquid crystal display is rotated at high speed and the display screen is switched in synchronization with the rotation period so that still images and videos can be viewed from a specific direction using visual afterimages.

  However, the conventional virtual display system is configured to display a predetermined image when the display screen of the liquid crystal display body faces a specific angle direction. Since the moving image is configured to be visible, an image displayed only once per rotation of the liquid crystal display for an observer in a specific angle direction, the brightness of the display screen Is the same as a display body visually recognized in a stationary state, there is a problem that the display becomes dark and the image cannot be clearly viewed.

  Further, in the above-described stereoscopic image display device, a stereoscopic image is displayed by projecting the cross-sectional image onto a rotating screen, so that each cross-section of the stereoscopic image is projected once per screen rotation. As described above, there are problems that the display is dark as described above, and that it is difficult to increase the sharpness of the stereoscopic image.

  Therefore, the present invention solves the above-described problems, and the problem is that in an electro-optical device in which an electro-optical display body having a display screen is configured to be able to rotate, the display is brightened and a clear image is displayed. It is to realize a configuration that can be visually recognized.

  The electro-optical device of the present invention is an electro-optical device having an electro-optical display body provided with a display screen, and a shaft support structure that guides the electro-optical display body so that the electro-optical display body can rotate. A plurality of display screens provided corresponding to different rotation angle positions are provided.

  According to this, when the electro-optic display body is rotated, a predetermined image is displayed at a specific rotation angle position by a plurality of display screens provided corresponding to different rotation angle positions. Since the image can be displayed on multiple display screens during one rotation of the device, the brightness of the display felt by the observer viewing the specific rotation angle position can be increased, and the sharpness of the image is improved. Can be made.

  In the present invention, it is preferable that the plurality of display screens are arranged at equiangular intervals around the rotation axis of the electro-optic display. According to this, when the electro-optic display body is rotated, the time timing when the display screen is directed to a specific rotation angle position can be set at equal intervals, so that flickering of the image is eliminated and natural image display is performed. Can do. In particular, the display characteristics of moving images can be improved. In addition, since the plurality of display screens are arranged at equiangular intervals around the rotation axis, the weight distribution around the rotation axis of the electro-optic display can be reduced, so that the electro-optic display can be smoothly rotated. It becomes possible to make it.

  In the present invention, it is preferable that the side edge portion of the display body portion having one display screen is arranged so as to overlap the side end surface of the display body portion having another display screen adjacent thereto. . According to this, the side edge portion of the display body portion having one display screen (for example, a display panel to be described later, the same applies hereinafter) overlaps the side end face of the display body portion having another display screen. When the display screen is visually recognized, the side end surfaces of the display body portions of the other display screens are hardly visible on the outside of the display screen, so that the display quality felt by the observer can be improved. In particular, when the electro-optic display is rotated in a direction in which another display screen is visually recognized next to one display screen, an end portion of the display image in the rotation direction can be visually recognized. In order to further enhance this effect, it is desirable that one display screen itself, not the display body portion of one display screen, overlap with the side end face of the adjacent display body portion.

  In the present invention, it is preferable that the plurality of display screens are configured to display an image by light supplied from a common illumination device. According to this, power consumption can be reduced by illuminating a plurality of display screens with a common illumination device.

  An electronic apparatus according to an aspect of the invention includes the electro-optical device according to any one of the above, a driving unit that rotationally drives the electro-optical display body, and a display control unit that controls display of the display screen of the electro-optical display body. It is characterized by having. Examples of the electronic device of the present invention include a display device that can visually recognize the same or different images from multiple directions, a display device that can visually recognize a stereoscopic image, and an image projection device that can project images in multiple directions.

  Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, although each embodiment described below is described as an electronic apparatus (display device) including the electro-optical device according to the present invention, it is configured as a single electro-optical device mounted on various electronic devices.
