Display device
View Patent ↗A receiving container for a display device includes a bottom plate, a sidewall and a grounding unit. The sidewall is extended from the bottom plate to define a receiving space. The grounding unit is integrally formed with the bottom plate. The grounding unit includes a grounding member that grounds a circuit board received in the receiving space. The circuit board includes a grounding electrode and the grounding member corresponds to the grounding electrode. The grounding member is formed on a rear surface of the bottom plate. The grounding member may include a protrusion or a projected portion having an elastic structure.
1. A backlight assembly, comprising:
a light source generating light;
a single unitary indivisible bottom chassis configured to receive the light source, the bottom chassis being electrically conductive and comprising:
a bottom plate comprising a front surface facing the light source, and a rear surface opposite to the front surface;
a sidewall extending from the bottom plate to define a receiving space configured to receive the light source; and
a grounding member on the rear surface of the bottom plate, the grounding member integrally formed with the bottom plate;
an upper frame coupled to the bottom chassis;
a circuit board disposed on the rear surface of the bottom plate; and
an insulation layer disposed between the circuit board and the rear surface of the bottom plate,
wherein
the insulation layer defines an opening exposing the circuit board and a portion of the rear surface of the bottom plate, and through which the grounding member protrudes, and
the grounding member comprises:
an extension portion which extends toward the circuit board in a first direction; and
a contact portion which further extends from the extension portion in a second direction different from the first direction, and contacts the circuit board.
2. The backlight assembly of claim 1 , wherein
the circuit board comprises a grounding electrode; and
the contact portion of the grounding member contacts the grounding electrode.
3. The backlight assembly of claim 2 , wherein the extension portion is extended obliquely toward the circuit board and the contact portion is extended substantially parallel with the circuit board.
4. The backlight assembly of claim 3 , wherein the contact portion and the grounding electrode contact with each other by face-to-face contact.
5. The backlight assembly of claim 1 , wherein an opening is formed on an area of the bottom plate corresponding to the grounding member.
6. A display device comprising:
a display panel displaying an image;
a circuit board providing the display panel with a driving signal; and
a backlight assembly, comprising:
a light source generating light;
a single unitary indivisible bottom chassis configured to receive the light source, the bottom chassis being electrically conductive and comprising:
a bottom plate comprising a front surface facing the light source, and a rear surface opposite to the front surface, the circuit board disposed on the rear surface of the bottom plate; and
a sidewall extending from the bottom plate to define a receiving space configured to receive the light source; and
a grounding member on the rear surface of the bottom plate, the grounding member integrally formed with the bottom plate;
an upper frame coupled to the bottom chassis configured to receive the display panel; and
an insulation layer disposed between the circuit board and the rear surface of the bottom plate,
wherein
the insulation layer defines an opening exposing the circuit board and a portion of the rear surface of the bottom plate, and through which the grounding member protrudes, and
the grounding member comprises:
an extension portion which extends toward the circuit board in a first direction; and
a contact portion which further extends from the extension portion in a second direction different from the first direction, and contacts the circuit board.
7. The display device of claim 6 , wherein
the circuit board comprises a grounding electrode; and
the contact portion of the grounding member contacts the grounding electrode.
8. The display device of claim 7 , wherein the extension portion is extended obliquely toward the circuit board and the contact portion is extended substantially parallel with the circuit board.
9. The display device of claim 8 , wherein the contact portion and the grounding electrode contact with each other by face-to-face contact.
10. The display device of claim 6 , wherein an opening is formed on an area of the bottom plate corresponding to the grounding member.
