Abstract

Provided is a display apparatus. The display apparatus includes: a display panel; a chassis supporting the display panel; a printed circuit board on which an electronic component is mounted; and a supporter inserted in the printed circuit board, wherein the printed circuit board includes a first surface facing the chassis, a second surface facing a direction opposite to the first surface, and a through hole penetrating the first surface and the second surface. The supporter includes: a head fixed on the second surface of the printed circuit board; a first body positioned inside the through hole, and extending from the head toward the chassis; and a second body extending from the first body, and protruding from the through hole toward the chassis.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel;
a chassis supporting the display panel;
a printed circuit board on which an electronic component is mounted, the printed circuit board comprising a first surface facing the chassis, a second surface facing a direction opposite to the first surface, and a through hole penetrating the first surface and the second surface; and
a supporter inserted in the through hole,
wherein the supporter comprises:
a head fixed on the second surface of the printed circuit board;
a first body positioned inside the through hole, and extending from the head toward the chassis;
a second body extending from the first body; configured to reduce interference between the electronic component mounted on the printed circuit board and the chassis, the second body protruding from the through hole toward the chassis with a separation distance therebetween;
an insulating sheet positioned on a side of the chassis facing the first surface of the printed circuit board; and
wherein a width of the second body is greater than a width of the first body.

2. The display apparatus of claim 1 , wherein the head of the supporter is clinched.

3. The display apparatus of claim 1 , wherein the second body further comprises a bent portion adjacent to the chassis.

4. The display apparatus of claim 1 , wherein the second body further comprises a projection having a width greater than a width of the through hole, wherein the supporter is configured to be caught by the first surface via the projection upon insertion into the through hole.

5. The display apparatus of claim 1 , wherein a lead of the electronic component mounted on the printed circuit board protrudes toward the chassis with respect to the first surface of the printed circuit board, and
a length of the second body is greater than a length of a portion of the lead of the electronic component protruding outward of the printed circuit board from the first surface.

6. The display apparatus of claim 1 , wherein the head is soldered on the second surface,
the second body is soldered on the first surface, and
a via hole is provided inside the supporter.

7. The display apparatus of claim 1 , further comprising a cover spaced from the chassis.

8. The display apparatus of claim 1 , further comprising a light source comprising light emitting circuitry configured to provide light to the display panel.

9. The display apparatus of claim 3 , wherein the second body further comprises an extension portion extending from the bent portion toward the first surface of the printed circuit board.

10. The display apparatus of claim 5 , wherein the lead is located inside the supporter, and
the lead is fixed in the supporter by soldering.

11. The display apparatus of claim 7 , wherein the head of the supporter is located between the second surface of the printed circuit board and the cover, and
the second body of the supporter is located between the first surface of the printed circuit board and the chassis.

12. The display apparatus of claim 10 , wherein the second body further comprises a plurality of solder reinforcement holes arranged along a circumferential direction of the second body.
