Mobile-object-mounted display device
According to the present invention, there is provided a mobile-object-mounted display device ( 1, 1 A) that is mounted on a mobile object ( 20 ) and performs display toward an outside of the mobile object ( 20 ), including one or a plurality of light emitting elements ( 3 d ) and a light emitting element support body ( 3 e ) that supports the one or plurality of light emitting elements ( 3 d ) along a surface having a three-dimensional shape.
1. A screen grille that is mounted on a vehicle and performs display toward an outside of the vehicle, the screen grille comprising:
a plurality of light emitting elements;
a plate-shaped light emitting element support body that has a front surface, the front surface being a curved surface formed along a surface of the vehicle, the surface having a three-dimensional shape, and that supports the plurality of light emitting elements along the front surface;
an outer cover that is disposed in front of the plurality of light emitting elements and has translucency; and
an interposing member interposed between the light emitting element support body and the outer cover,
wherein the light emitting element support body is curved in a vertical cross-section in a front-rear direction such that the front surface is closer to a vertical plane as it goes toward a front end of the light emitting element support body, and is curved in a horizontal cross-section such that the front surface faces in a left-right direction as it goes toward ends of the light emitting element support body in the left-right direction from a center of the light emitting element support body in the left-right direction,
the plurality of light emitting elements are collectively disposed in a display area provided in a central portion of the light emitting element support body when viewed from an outer cover side,
the interposing member is an annular plate member having an opening in a center thereof, has a frame shape surrounding the display area when viewed from the outer cover side, and is disposed ahead of the plurality of light emitting elements,
an inner edge portion forming the opening, of the interposing member is disposed to overlap light emitting elements arranged at an outer edge portion of the display area, of the plurality of light emitting elements when viewed from the outer cover side.
2. The screen grille according to claim 1 , wherein the plurality of light emitting elements are arranged along the front surface.
3. The screen grille according to claim 2 , wherein the light emitting elements are mounted on the front surface of the light emitting element support body that is a circuit board.
4. The screen grille according to claim 2 , wherein a tape material to which the light emitting elements are attached is pasted on the front surface of the light emitting element support body that is a support substrate.
5. The screen grille according to claim 2 , wherein the plurality of light emitting elements are arranged in two directions along the surface having the three-dimensional shape, the two directions being perpendicular to each other.
6. The screen grille according to claim 1 , wherein a buffer space is provided between the light emitting elements and the outer cover.
7. The screen grille according to claim 6 further comprising:
a rear member that is coupled to the outer cover from behind and forms a closed space that accommodates the light emitting elements with the outer cover therebetween.
8. The screen grille according to claim 1 ,
wherein the display area has a rectangular shape having an upper edge portion, a lower edge portion, a left edge portion, and a right edge portion when viewed from the outer cover side as the outer edge portion, and
the interposing member has a bilaterally symmetrical shape that overlaps the light emitting elements arranged at the upper edge portion, the lower edge portion, the left edge portion, and the right edge portion of the display area when viewed from the outer cover side.
9. The screen grille according to claim 1 , wherein the screen grille is configured to perform at least one of display of a pictogram and display of a character.
10. A screen grille that is mounted on a vehicle and performs display toward an outside of the vehicle, the screen grille comprising:
one light emitting element;
a plate-shaped light emitting element support body that has a front surface, the front surface being a curved surface formed along a surface of the vehicle, the surface having a three-dimensional shape, and that supports the one light emitting element along the front surface;
an outer cover that is disposed in front of the one emitting element and has translucency; and
an interposing member interposed between the light emitting element support body and the outer cover,
wherein the light emitting element support body is curved in a vertical cross-section in a front-rear direction such that the front surface is closer to a vertical plane as it goes toward a front end of the light emitting element support body, and is curved in a horizontal cross-section such that the front surface faces in a left-right direction as it goes toward ends of the light emitting element support body in the left-right direction from a center of the light emitting element support body in the left-right direction,
the one light emitting element is disposed in a display area provided in a central portion of the light emitting element support body when viewed from an outer cover side,
the interposing member is an annular plate member having an opening in a center thereof, has a frame shape surrounding the display area when viewed from the outer cover side, and is disposed ahead of the one light emitting element,
an inner edge portion forming the opening, of the interposing member is disposed to overlap a portion arranged at an outer edge portion of the display area, of the one light emitting element when viewed from the outer cover side.
11. The screen grille according to claim 10 , wherein one organic EL element is provided as the one light emitting element.
