The numbers and rows are preferably odd columns and odd rows.

(Embodiment 2)
Next, an image display apparatus 1A according to Embodiment 2 of the present invention will be described with reference to FIG. FIG. 3 is a front view of an image display apparatus according to Embodiment 3 of the present invention.

  The difference between the image display device 1A according to the second embodiment and the image display device 1 according to the first embodiment is the type of screen size of the display panel 3. In other words, the image display device 1 </ b> A according to the present embodiment is configured using the display panels 31 and 32 having two types of screen sizes as the display panel 3.

  Here, as for the screen sizes of the display panels 31 and 32, as in the first embodiment, the aspect ratio of the display panel 31 is 9:16 and the aspect ratio of the display panel 32 is 4.5: 8. The screen size is selected so that the aspect ratio is 9:16, and then the display panel 31 having the larger screen size is arranged in the approximate center of the display screen 2A of the image display device 1A. Two display panels 32 having smaller screen sizes are arranged side by side on the upper side, lower side, left side, and right side of the panel 31. Thereby, the display screen 2A of the image display device 1A is configured.

Therefore, the frame 5 does not block a portion with a large amount of information or a portion with a high degree of attention in the display image, thereby reducing the occurrence of the problem that the frame 5 interferes with image display. it can. As a result, the visual impression of the displayed image can be improved and a good image display can be realized.

(Embodiment 3)
Next, an image display device 1B according to Embodiment 3 of the present invention will be described with reference to FIGS. 4 is a diagram showing an example when an image is displayed on the display screen of the image display apparatus according to Embodiment 2 of the present invention in FIG. 3, and FIG. 5 is an image according to Embodiment 3 of the present invention. It is a figure which shows the structure of a display apparatus roughly.

  When an image display apparatus is configured by arranging a plurality of display panels in a planar shape, the shape of the display screen may not necessarily be a ratio of 9:16, which is an aspect ratio for displaying a general image, On the contrary, it may not even be a rectangle. For example, also in the case of the image display device 1A according to Embodiment 2 of the present invention, as shown in FIG. 3, the overall shape of the display screen 2A is not substantially rectangular (substantially rectangular) but It is a non-rectangular shape (non-rectangular shape) such that a part of the side protrudes upward and downward.

  When an image is displayed on the display screen 2A having such a shape, as shown in FIG. 4, a non-image display area 20 is generated around the displayed image 10 (in FIG. 4, above and below the image 10). End up. That is, the peripheral pixel area of the display screen 2 </ b> A (the part protruding vertically in FIG. 4) becomes the non-image display area 20. In this case, when the user views the image 10, the visual impression is deteriorated. As a result, there arises a problem that a good image display is hindered. The non-image display area 20 is a pixel area of the display panel 3 and is a displayable area, but is an area that is not necessary when displaying one rectangular frame image. The non-image display area 20 is an area displayed in black, for example, in a band shape.

  Therefore, in the image display device 1B according to Embodiment 3 of the present invention, the escutcheon 6 is provided so as to cover at least a part of the periphery of the display screen. The escutcheon 6 is an outer frame having an opening, and is constituted by a light shielding member. The escutcheon 6 can be formed of, for example, a resin material or a metal material.

Thereby, the user visually recognizes the image through the substantially rectangular opening area opened inside the escutcheon 6.

  Further, in FIG. 5, the contour line (inner contour line) inside the opening of the escutcheon 6 is configured to be closer to the inner side of the display screen 2A than the outer contour line (outer contour line) of the display screen 2A. . As a result, a part of the pixel area of the plurality of display panels 31 and 32 is covered with the escutcheon 6. Therefore, in this case, a part of the image displayed on the display screen 2A is shielded (cut) by the escutcheon 6, so that the user visually recognizes an image in which a part of the periphery of the display image is cut. It will be.

  As described above, according to the image display device 1B according to the present embodiment, since the escutcheon 6 having a substantially rectangular opening is provided, the display screen 2A has a non-rectangular shape as shown in FIG. Even if the non-image display area 20 is generated around the image 10 displayed on the screen 2 </ b> A, the non-image display area 20 is hidden by the escutcheon 6. Thereby, as a display image of the image display device 1B, an image through the substantially rectangular opening of the escutcheon 6, that is, an approximately rectangular image is always displayed. Therefore, when the user views the image, it is possible to prevent the occurrence of the problem that the visual impression is deteriorated and hinders good image display. As a result, the visual impression is improved, so that a good image display can be realized.

  In the present embodiment, since the shape of the image visually recognized by the user can be defined by the opening of the escutcheon 6, the screen sizes of the plurality of display panels 3 can be set regardless of the shape of the entire display screen in the image display device.

Thus, by providing the escutcheon 6, it becomes possible to greatly improve the degree of freedom of the combination of the plurality of display panels 3, and a multi-screen image display device can be easily obtained by using an existing size display panel. Can be realized.

  In the present embodiment, the aspect ratio of the opening of the escutcheon 6 is preferably the same as the aspect ratio of the image displayed on the display screen 2A. Thereby, the rate at which the displayed image is cut can be reduced as much as possible. The aspect ratio of the opening of the escutcheon 6 can be 16: 9, which is the same as the aspect ratio of the broadcast wave image, for example.

  In the present embodiment, a part of the image displayed on the display screen 2A is cut by the escutcheon 6, but the image displayed on the display screen 2A is not necessarily cut. You don't have to. Whether or not to cut the image actually displayed on the display screen 2A can be adjusted by the shape and relative positional relationship between the display screen 2A and the opening of the escutcheon 6, and the image displayed on the display screen 2A is cut. It can also comprise so that a user can visually recognize all without doing.

  In the present embodiment, the case where the overall shape of the display screen is a non-rectangular shape has been described. That is, when the overall shape of the display screen is substantially rectangular, the aspect ratio of the substantially rectangular opening of the escutcheon 6 can be applied to a case where the aspect ratio is different from the aspect ratio of the display screen.

  Furthermore, when the overall shape of the display screen is approximately rectangular, it is preferable to match the aspect ratio of the image displayed on the display screen with the aspect ratio of the approximately rectangular display screen, but it is difficult to match temporarily. Even in this case, as shown in FIG. 5, it is possible to realize good image display by providing an escutcheon around the display screen.

  Further, the method of displaying an image of one frame using a partial area of the display screen 2A is not limited to the method shown in FIG. 4, but the upper area, the lower area, the left area, and the right area of the display screen 2A. An image display method may be employed in which an area in which an image is displayed is set to a desired aspect ratio by causing an area in which an image is not displayed to exist in at least a part of the area. In addition, when performing image display in which an image of one frame is displayed in a partial area of the display screen 2A, it can be realized by controlling the drive systems of a plurality of display panels constituting the image display device as necessary. Needless to say.
