Multi-display system and translucent cover used thereby
A multi display system ( 10 ) includes a plurality of display panels ( 100 ) disposed adjacently to each other via a boundary portion ( 20 ), and a translucent cover ( 113 ) disposed on the plurality of display panels ( 100 ). The translucent cover ( 113 ) is disposed so as to cover the boundary portion ( 20 ) and overlapping with both of the plurality of display panels ( 100 ) which are disposed adjacently. The translucent cover ( 113 ) is constituted by a supporting portion ( 113 P) which covers at least part of the display panel excluding the boundary portion ( 20 ), and a portion which is continuous to the supporting portion ( 113 P) and includes a concave portion ( 113 C) formed on the observer side in a position facing the boundary portion ( 20 ).
1. A multi display system comprising:
a plurality of display panels which are disposed adjacently to each other via a boundary portion; and
a translucent cover provided on the plurality of display panels, to cover the boundary portion and overlapping with both of the plurality of display panels which are disposed adjacently to each other; wherein
the translucent cover is defined by a supporting portion which covers a part of the display panel other than the boundary portion, and a portion continuous to the supporting portion, the portion continuous to the supporting portion having a concave portion defined on an observer side in a position facing the boundary portion, the translucent cover being directly attached to a surface of the part of the display panel such that there is no empty space between the translucent cover and the surface of the part of the display panel;
each of the plurality of display panels includes a display area which contributes to display and a frame area provided around the display area;
the concave portion covers at least part of the display area;
a width of the translucent cover in a direction perpendicular to an extending direction of the boundary portion and parallel to the surface of the part of the display panel is larger than a width of the boundary portion perpendicular to the extending direction of the boundary portion and smaller than a width of the display panel perpendicular to the extending direction of the boundary portion; and
the concave portion has an asymmetric shape in the boundary portion;
wherein the boundary portion includes the frame area of each of the adjacent display panels, and part of light emitted from the display panel is emitted from an area corresponding to the boundary portion of the translucent cover in the concave portion.
2. The multi display system of claim 1 , further comprising a light diffusing layer or a reflection preventing layer formed on the translucent cover.
3. The multi display system of claim 1 , wherein the concave portion has a surface defined by two planes which are not parallel to each other.
4. A multi display system comprising:
a plurality of display panels which are disposed adjacently to each other via a boundary portion; and
a translucent cover provided on the plurality of display panels, to cover the boundary portion and overlapping with both of the plurality of display panels which are disposed adjacently to each other; wherein
the translucent cover is defined by a supporting portion which covers at least part of the display panel other than the boundary portion, and a portion continuous to the supporting portion, the portion continuous to the supporting portion having a concave portion defined on an observer side in a position facing the boundary portion;
the concave portion has a single continuous concave curved surface which covers the display areas of the plurality of display panels and the boundary portion; and
the concave portion has an asymmetric shape in the boundary portion;
each of the plurality of display panels includes a display area which contributes to display and a frame area provided around the display area; wherein the boundary portion includes the frame area of each of the adjacent display panels, and part of light emitted from the display panel is emitted from an area corresponding to the boundary portion of the translucent cover in the concave portion.
5. The multi display system of claim 1 , wherein the display panel has a plurality of pixels, and a display signal based on the information of image to be displayed in the boundary portion is applied to pixels that are closer to the boundary portion.
6. The multi display system of claim 1 , wherein the shape of the concave portion is defined depending on an observation direction of the observer.
7. The multi display system of claim 1 , wherein an optical sensor is provided in the boundary portion.
8. The multi display system of claim 1 , wherein the concave portion covers both the display areas and the frame areas of the plurality of display panels.
