Abstract

A display apparatus comprises a display panel; a heat sink plate coupled to a bottom surface of the display panel and having a coupling member that extends in a semicircular shape at one end and protrudes in a direction toward the bottom surface of the display panel; and a guide panel having a connection member at one end that is coupled to the coupling member in a rotation or sliding manner and connected to a bottom surface a printed circuit board (PCB) connected to the display panel, wherein the printed circuit board is detachably coupled to a bottom surface of the heat sink plate.

Claims (40)

1. A display apparatus comprising:

a display panel;

a heat sink plate coupled to a bottom surface of the display panel and having a coupling member that extends in a semicircular shape at one end and protrudes in a direction toward the bottom surface of the di splay panel; and

a guide panel having a connection member at one end that is coupled to the coupling member in a rotation or sliding manner and connected to a bottom surface of a printed circuit board (PCB) that is connected to the display panel,

wherein the printed circuit board is detachably coupled to a bottom surface of the heat sink plate, and

wherein, in a state in which the guide panel and the heat sink plate are coupled, an air gap is formed in an interval between surfaces of the guide panel and the heat sink plate which face each other.

2. The display apparatus of claim 1 , wherein the connection member of the guide panel is coupled to the coupling member of the heat sink plate and has a same center of rotation on an inner circumference surface of the coupling member of the heat sink plate.

3. The display apparatus of claim 2 , wherein the coupling member and the connection member have a plurality of open grooves that are at least partially open in a longitudinal direction.

4. The display apparatus of claim 3 , wherein the plurality of open grooves include a first open groove and a second open groove, and

wherein the first open groove is disposed on a surface of the coupling member and connection member toward a center of the semicircular shape and the second open groove is disposed between the surfaces of the coupling member and connection member facing to each other.

5. The display apparatus of claim 4 , wherein the second open groove has a smaller open size than that of the first open groove.

6. The display apparatus of claim 1 , wherein the guide panel and the heat sink plate are formed of at least one of aluminum (Al), magnesium (Mg), silver (Ag), gold (Au), and copper (Cu).

7. The display apparatus of claim 1 , further comprising a stopper limiting a coupling position between the coupling member and the connection member.

8. The display apparatus of claim 7 , the stopper limits a sliding distance of the coupling member with respect to the connection member in a longitude direction.

9. A display apparatus comprising:

a display panel;

a heat sink plate coupled to a bottom surface of the display panel and having a coupling member that extends in a semicircular shape at one end and protrudes in a direction toward the bottom surface of the display panel; and

a guide panel having a connection member at one end that is coupled to the coupling member in a rotation or sliding manner and connected to a bottom surface of a printed circuit board (PCB) that is connected to the display panel,

wherein the printed circuit board is detachably coupled to a bottom surface of the heat sink plate, and

wherein the guide panel includes a fixing end that protrudes in a direction toward the bottom surface of the heat sink plate to allow another end of the guide panel to contact the bottom surface of the heat sink plate when the guide panel is completely coupled to the heat sink plate.

10. The display apparatus of claim 9 , further comprising a fixing member configured to fix the fixing end to the bottom surface of the heat sink plate.

11. The display apparatus of claim 10 , wherein the fixing member includes a tape or a hook connection structure.

12. The display apparatus of claim 9 , wherein the connection member of the guide panel is coupled to the coupling member of the heat sink plate and has a same center of rotation on an inner circumference surface of the coupling member of the heat sink plate.

13. The display apparatus of claim 12 , wherein the coupling member and the connection member have a plurality of open grooves that are at least partially open in a longitudinal direction.

14. The display apparatus of claim 13 , wherein the plurality of open grooves include a first open groove and a second open groove, and

wherein the first open groove is disposed on a surface of the coupling member and connection member toward a center of the semicircular shape and the second open groove is disposed between the surfaces of the coupling member and connection member facing to each other.

15. The display apparatus of claim 14 , wherein the second open groove has a smaller open size than that of the first open groove.

16. The display apparatus of claim 9 , further comprising a stopper limiting a coupling position between the coupling member and the connection member.

17. The display apparatus of claim 16 , the stopper limits a sliding distance of the coupling member with respect to the connection member in a longitude direction.

18. A display apparatus comprising:

a display panel;

a heat sink plate coupled to a bottom surface of the display panel and having a coupling member extended to one end to protrude in a direction toward the bottom surface of the display panel;

a guide panel including a connection member at one end that is rotatably or slidably engaged with the coupling member of the heat sink plate;

a printed circuit board connected to the display panel and detachably engaged with a bottom surface of the heat sink plate; and

a stopper configured to limit a coupling position between the coupling member and the connection member,

wherein the heat sink plate and the guide panel are separated apart from each other by an air gap.

19. The display apparatus of claim 18 , the stopper limits a sliding distance of the coupling member with respect to the connection member in a longitude direction.

20. The display apparatus of claim 18 , wherein the guide panel includes a fixing end that protrudes in a direction toward the bottom surface of the heat sink plate to allow another end of the guide panel to contact the bottom surface of the heat sink plate when the guide panel is completely coupled to the heat sink plate.

21. The display apparatus of claim 20 , further comprising a fixing member configured to fix the fixing end to the bottom surface of the heat sink plate.

22. The display apparatus of claim 18 , wherein the coupling member and the connection member have a plurality of open grooves that are at least partially open in a longitudinal direction.
