Display device with slimmer border portion
View Patent ↗A display device includes a display panel, a light source disposed on a rear side relative to the display panel, an optical member disposed on the rear side relative to the display panel, a light source housing component housing the light source, and first and second flat components extending in an outward direction relative to an opening edge of the light source housing component, the first and second flat components being substantially parallel to a rear face of the display panel, the second flat component being disposed closer to the display panel than the first flat component, the second flat component supporting the optical member.
1. A display device comprising:
a display panel;
a light source disposed on a rear side relative to the display panel;
an optical member disposed on the rear side relative to the display panel;
a rear chassis made of a piece of sheet metal and integrated as a one-piece, unitary member, the rear chassis including
a light source housing component that houses the light source,
a first flat component that extends outward from an opening edge of the light source housing component, and extends substantially parallel to a rear face of the display panel, and
a second flat component that extends outward relative to the first flat component and extends substantially parallel to the rear face of the display panel, the second flat component being disposed closer to the display panel than the first flat component, the second flat component supporting the optical member;
a front face housing covering an outer peripheral part of a front face of the display panel;
a rear face housing covering a rear face of the light source housing component from a rear of the display device, the rear face of the light source housing component forming a rear face of the rear chassis, the rear face housing being made of plastic; and
a fastening member disposed through a bore of the rear face housing and fastened to the first flat component of the rear chassis to fasten the rear face housing to the first flat component of the rear chassis.
2. The display device according to claim 1 , wherein
the first flat component extends outward with respect to a center of the light source housing component from the opening edge of the light source housing component, and
the second flat component extends outward with respect to the center of the light source housing component relative to the first flat component, the second flat component supporting the optical member from the rear side.
3. The display device according to claim 1 , further comprising
a first extending part extending towards the display panel from an outer peripheral part of the first flat component,
the second flat component extending outward from an end portion of the first extending part to sandwich an outer peripheral part of the optical member between the display panel and the second flat component.
4. The display device according to claim 3 , wherein
a peripheral edge portion between the first flat component and the first extending part has an inclined surface at a location corresponding to a corner of the display panel.
5. The display device according to claim 4 , wherein
the inclined surface has an overall triangular shape as viewed in a normal direction of the inclined surface.
6. The display device according to claim 4 , wherein
the inclined surface has an edge portion defining a corner of the peripheral edge portion between the first flat component and the first extending part, the edge portion of the inclined surface being slanted towards the display panel as moving towards the corner of the peripheral edge portion between the first flat component and the first extending part.
7. The display device according to claim 3 , wherein
the first extending part is inclined outward relative to a perpendicular direction perpendicular to the first flat component.
8. The display device according to claim 3 , wherein
a bend radius of a peripheral edge portion between the first extending part and the second flat component is larger at a location corresponding to a corner of the display panel than at a location corresponding to a middle portion of a side of the display panel.
9. The display device according to claim 3 , wherein
an overlapping width between the outer peripheral part of the optical member and the second flat component that is measured in a direction directing outward is smaller at a location corresponding to a corner of the display panel than at a location corresponding to a middle portion of a side of the display panel.
10. The display device according to claim 3 , further comprising
a second extending part extending from an end portion of the second flat component away from the display panel.
11. The display device according to claim 10 , wherein
the second flat component has a flat surface, a width between an inward peripheral edge of the flat surface of the second flat component and the second extending part that is measured in a direction directing outward is smaller at a location corresponding to a corner of the display panel than at a location corresponding to a middle portion of a side of the display panel.
12. The display device according to claim 1 , further comprising
a control switch disposed between the rear face housing and the first flat component to control the display device.
13. The display device according to claim 1 , wherein
the light source housing component, the first flat component and the second flat component are formed by stamping the piece of sheet metal.
14. The display device according to claim 1 , wherein
the light source housing component and the first flat component are formed by drawing the piece of sheet metal.
15. The display device according to claim 1 , wherein
the second flat component is formed by forming the piece of sheet metal.
16. The display device according to claim 1 , further comprising
a fastening member fastening the front face housing to the second flat component.
