Abstract

A display apparatus is provided. The display apparatus is an assembly of a display panel, a chassis, a circuit board and a board connection member. During operation, the display panel produces an image. The chassis includes a base supporting the display panel at the rear of the display panel, and a first protrusion protruding from the base in a direction away from the display panel. The circuit board is fixed at a position that is spaced apart from a rear surface of the chassis by a given gap and functions to electronically drive the display panel. The board connection member includes a chassis fixing portion, a board fixing portion and a connection supporter. The chassis fixing portion is connected to the first protrusion, the board fixing portion is connected to the circuit board, and the connection supporter is arranged between the circuit board and the chassis and connects the chassis fixing portion and the board fixing portion. Thus, the board connection members are used to fix the circuit board to the chassis during assembly.

Claims

1. A display apparatus comprising:

a display panel configured to produce an image;

a chassis comprising a base configured to support the display panel at the rear of the display panel and comprising a first protrusion protruding from the base in a direction away from the display panel;

a circuit board fixed to be spaced apart from a rear surface of the chassis by a predetermined gap, and configured to control the display panel; and

a circuit board connection member comprising a chassis fixing portion connected to the first protrusion, a board fixing portion connected to the circuit board, and a connection supporter arranged between the circuit board and the chassis configured to connect the chassis fixing portion and the board fixing portion so as to fix the circuit board to the chassis.

2. The apparatus of claim 1, wherein:

the circuit board comprises a board fixing hole formed therein at a position corresponding to the board fixing portion; and

the board fixing portion comprises an elastic board through portion having a diameter larger than a diameter of the board fixing hole configured to pass through the board fixing hole to be at least in part positioned at a rear side of the circuit board, a board insertion portion inserted into the board fixing hole, and a board supporting portion having a diameter larger than the diameter of the board fixing hole and connected to the connection supporter to support a front side of the circuit board.

3. The apparatus of claim 2, wherein the first protrusion includes a chassis fixing hole formed at a position corresponding to the chassis fixing portion, and the chassis fixing portion comprises:

an elastic chassis through portion having a diameter larger than a diameter of the chassis fixing hole configured to pass through the chassis fixing hole to be at least partly positioned at a front side of the first protrusion;

a chassis insertion portion inserted into the chassis fixing hole; and

a chassis supporter having a diameter larger than the diameter of the chassis fixing hole, the chassis supporter being connected to the connection supporter to support the chassis.

4. The apparatus of claim 2, wherein the circuit board connection member is a plastic spacer comprising the chassis fixing portion, the connection supporter and the board fixing portion being integrally formed.

5. The apparatus of claim 1, wherein:

the rear surface of the chassis comprises one or more bosses;

the circuit board includes a boss connection hole formed therein at a rear of the boss connection, wherein the bosses and the boss connection hole are located at corresponding positions; and

the circuit board and the chassis are connected by a boss fixing member passing through the boss connection hole.

6. The apparatus of claim 5, wherein the chassis further comprises a second protrusion protruding from the base in a direction away from the display panel and being connected to one of the one or more bosses.

7. The apparatus of claim 6, wherein the second protrusion is formed to have a height related to a gap between the base and the circuit board at a rear of the second protrusion.

8. The apparatus of claim 1, wherein the first protrusion is formed to have a height related to a gap between the base and the circuit board at a rear of the first protrusion.

9. The apparatus of claim 1, wherein a plurality of board connection members are fixed to the circuit board, and the height of at least one connection supporter is different from the height of another connection supporter.

10. The apparatus of claim 1, further comprising a supporter arranged between the base and the circuit board to support the circuit board against the base, wherein a height of the supporter between the base and the circuit board is different from a height of the connection supporter.

11. The apparatus of claim 1, wherein the display panel is a plasma display panel configured to produce an image through plasma discharge.
