Abstract

A display apparatus includes a backlight unit generating light, a bottom receiving member including a bottom portion and a first sidewall portion extending from the bottom portion to define a receiving space accommodating the backlight unit, an intermediate frame coupled to the bottom receiving member including a second sidewall portion facing the first sidewall portion and a cover portion extending inward from the second sidewall portion to cover an upper edge of the backlight unit, and a display panel on the cover portion for receiving the light from the backlight unit and displaying an image. The bottom receiving member includes a protrusion protruding outward from the first sidewall portion, and the intermediate frame includes a distance adjusting portion in an inner side surface of the second sidewall portion engaged with an outer surface of the protrusion to move the cover portion along a z-axis direction away from the bottom portion.

Claims

1. A display apparatus comprising:

a backlight unit configured to generate light;

a bottom receiving member comprising a bottom portion and a first sidewall portion extending from the bottom portion to define a receiving space accommodating the backlight unit;

an intermediate frame coupled to the bottom receiving member, the intermediate frame comprising a second sidewall portion facing the first sidewall portion of the bottom receiving unit and a cover portion extending inward from the second sidewall portion to cover an upper edge of the backlight unit; and

a display panel on the cover portion for receiving the light from the backlight unit and displaying an image, wherein the bottom receiving member comprises a protrusion protruding outward from the first sidewall portion, and the intermediate frame comprises a distance adjusting portion in an inner side surface of the second sidewall portion engaged with an outer surface of the protrusion, and wherein the engagement between the distance adjusting portion and the protrusion is configured to move the cover portion along a z-axis direction away from the bottom portion.

2. The display apparatus of claim 1, wherein the distance adjusting portion is a groove.

3. The display apparatus of claim 1, wherein the protrusion has a curved shape in which a gradient of the protrusion relative to the first sidewall portion increases along the z-axis direction from a center of the protrusion.

4. The display apparatus of claim 3, wherein the distance adjusting portion has a curved or inclined shape configured to move in the z-axis direction along the outer surface of the protrusion.

5. The display apparatus of claim 1, wherein the outer surface of the protrusion has an inclined structure inclined toward the first sidewall portion as the protrusion extends along the z-axis direction.

6. The display apparatus of claim 5, wherein the distance adjusting portion has a curved or inclined shape configured to move in the z-axis direction along the outer surface of the protrusion.

7. The display apparatus of claim 1, further comprising a top receiving member comprising a third sidewall portion facing the second sidewall portion of the intermediate frame and a front surface portion extending inward from the third sidewall portion to fix the upper edge of the display panel, wherein the top receiving member, the intermediate frame, and the bottom receiving member are coupled to each other by a screw.

8. The display apparatus of claim 7, wherein:

the first sidewall portion of the bottom receiving member comprises at least one engaging protrusion engaged with the screw;

the third sidewall portion of the top receiving member comprises an engaging recess corresponding to the engaging protrusion on the bottom receiving member; and

the protrusion and the distance adjusting portion are located at positions within a set range from the engaging protrusion and the engaging recess.

9. The display apparatus of claim 8, wherein the set range is a distance that the distance adjusting portion moves in the z-axis direction along the outer surface of the protrusion when a force is applied to the intermediate frame by the screw being engaged with the top receiving member and the bottom receiving member.

10. The display apparatus of claim 1, wherein the backlight unit comprises:

a light source that emits the light;

a light guide member that guides the light to the display panel; and

an optical sheet disposed between the light guide member and the display panel, the cover portion of the intermediate frame covering an edge of the optical sheet.

11. The display apparatus of claim 10, wherein the light source comprises:

a printed circuit board adjacent to at least one side surface of the light guide member; and

a plurality of light emitting diodes on the printed circuit board.

12. A method of assembling a display apparatus, the method comprising:

positioning a backlight unit in a receiving container defined by a bottom receiving member comprising a bottom portion and a first sidewall portion extending from the bottom portion;

placing an intermediate frame comprising a second sidewall portion facing the first sidewall portion and a cover portion extending inward from the second sidewall portion to cover an upper edge of the backlight unit, wherein the intermediate frame comprises a distance adjusting portion defined in an inner side surface of the second sidewall portion engaged with an outer surface of a protrusion protruding outward from the first sidewall portion of the bottom receiving member;

placing a display panel on the cover portion of the intermediate frame, wherein the display panel is configured to receive light from the backlight unit and display an image; and

adjusting a distance between the cover portion and the backlight unit, the adjusting of the distance comprising moving the cover portion along a z-axis direction away from the bottom portion by sliding the protrusion along the distance adjusting portion.

13. The method of claim 12, wherein the distance adjusting portion is a groove.

14. The method of claim 12, further comprising coupling a top receiving member to the bottom receiving member, wherein the top receiving member comprises a third sidewall portion facing the second sidewall portion of the intermediate frame and a front surface portion extending inward from the third sidewall portion to fix an upper edge of the display panel.

15. The method of claim 14, wherein the top receiving member is coupled to the bottom receiving member by a screw, and wherein a force generated when the screw is engaged with the top and bottom receiving members performs the adjusting of the distance between the cover portion and the backlight unit comprises moving the intermediate frame along the z-axis direction away from the bottom portion.

16. The method of claim 12, wherein the adjusting of the distance between the cover portion and the backlight unit further comprises adjusting a position of the protrusion in the z-axis direction.

17. The method of claim 12, wherein the protrusion has a curved shape in which a gradient of the protrusion relative to the first sidewall portion increases along the z-axis direction from a center point of the protrusion.

18. The method of claim 17, wherein the distance adjusting portion has a curved or inclined shape configured to move in the z-axis direction along the outer surface of the protrusion.

19. The method of claim 12, wherein the outer surface of the protrusion has an inclined structure inclined toward the first sidewall portion as the protrusion extends along the z-axis direction.

20. The method of claim 19, wherein the distance adjusting portion has a curved or inclined shape configured to move in the z-axis direction along the outer surface of the protrusion.
