Abstract

A display apparatus includes a bottom plate, a mold frame coupled to the bottom plate to define a receiving space, a backlight unit which is configured to be accommodated in the receiving space and generate light; a sliding recess which is defined by portions of the mold frame and exposed to the receiving space, an inlet portion which is defined by the mold frame and bottom plate, and exposes the receiving space and a side portion of the backlight unit accommodated in the receiving space; a side mold which covers the side portion of the accommodated backlight unit exposed by the inlet portion; and a display unit which is on an upper end of the mold frame and configured to receive the light to display an image. The backlight unit is accommodated in the receiving space through the inlet portion and along the sliding recess.

Claims

1. A display apparatus comprising:

a bottom plate;

a mold frame which is configured to be coupled to the bottom plate to define a receiving space,

a backlight unit which is configured to be accommodated in the receiving space and generate light;

a sliding recess which is defined by portions of the mold frame and exposed to the receiving space,

an inlet portion which is defined by the mold frame and bottom plate, and exposes the receiving space and a side portion of the backlight unit accommodated in the receiving space;

a side mold which covers the side portion of the accommodated backlight unit exposed by the inlet portion; and

a display unit which is on an upper end of the mold frame and configured to receive the light to display an image,

wherein the backlight unit is accommodated in the receiving space through the inlet portion and along the sliding recess.

2. The display apparatus of claim 1, wherein

the bottom plate has a rectilinear shape having four sides in a plan view,

the mold frame comprises a sidewall which extends from an edge of the bottom plate and along three sides of the bottom plate, and

the inlet portion of the mold frame is defined at a remaining side of the bottom plate.

3. The display apparatus of claim 2, wherein

the mold frame further comprises a protrusion which is extended from a lower end of the sidewall and toward the receiving space, and faces the bottom plate, and

the protrusion of the mold frame is coupled to the bottom plate by a first engaging member received by the protrusion and the bottom plate.

4. The display apparatus of claim 2, further comprising a heat sink plate which is configured to be disposed under the backlight unit at the inlet portion and coupled to the bottom plate,

wherein the side mold is coupled to the heat sink plate.

5. The display apparatus of claim 4, wherein the backlight unit comprises:

a light source part which is configured to emit the light; and

a light guide plate which is configured to guide the emitted light to the display unit.

6. The display apparatus of claim 5, wherein

the light source part comprises:

a light source mounting bar adjacent to a light incident side surface of the light guide plate, and

a plurality of light sources arranged on the light source mounting bar, and

the light source mounting bar is between the side mold and the light incident side surface of the light guide plate.

7. The display apparatus of claim 6, wherein the side mold and the light source mounting bar are coupled to the heat sink plate by a second engaging member.

8. The display apparatus of claim 6, wherein the side mold comprises a guide bar which is protruded from an inner side surface thereof toward the light incident side surface of the light guide plate and maintains a distance between the light source part and the light incident side surface of the light guide plate.

9. The display apparatus of claim 5, further comprising an opposite recess which is defined by portions of the mold frame, exposed to the receiving space, opposite to the inlet portion and continuous with the sliding recess,

wherein

the light guide plate comprises an opposite side surface opposing a light incident side surface thereof, and

the backlight unit further comprises a guide member which is in the opposite recess, faces the opposite side surface of the light guide plate and guides the light guide plate to an initial position in the receiving space.

10. The display apparatus of claim 9, wherein the guide member comprises a deformable material which absorbs an impact.

11. The display apparatus of claim 1,

wherein the backlight unit comprises an optical sheet which is between the light guide plate and the display unit, the optical sheet comprising an extension portion extended from a side thereof and toward the mold frame, and

further comprising a fixing recess which is defined extended from an inner sidewall of the mold frame, exposed to the receiving space and accommodates the extension portion of the optical sheet therein.

12. The display apparatus of claim 11, wherein

a sliding direction is defined from the inlet portion to a side of the display apparatus opposite to the inlet portion,

the extension portion of the optical sheet comprises two distal corners defined by a first edge of the extension portion parallel to the sliding direction meeting second edges of the extension portion vertical to the sliding direction, and

a distal corner among the two distal corners of the extension portion further from the inlet portion is chamfered to define an inclination side of the extension portion and is firstly inserted into the receiving space when the backlight unit is accommodated into the receiving space.

13. The display apparatus of claim 12, wherein a second edge among the second edges of the extension portion vertical to the sliding direction defines a catching edge of the extension portion, and restricts withdrawal of the extension portion from the fixing recess and movement of the optical sheet in a direction opposite to the sliding direction.

14. The display apparatus of claim 1, wherein the mold frame and the side mold each comprises a step portion at an upper end thereof and upon which the display unit is disposed.

15. The display apparatus of claim 14, further comprising an adhesive member which is between the step portion and the display unit, and fixes the display unit to the mold frame and the side mold.

16. A method of manufacturing a display apparatus, comprising

coupling a mold frame to a bottom plate to define a receiving space, wherein a sliding recess is defined by portions of the mold frame and exposed to the receiving space, and an inlet portion is defined by the mold frame and bottom plate and exposes the receiving space,

inserting a backlight unit which is configured to generate light, through the inlet portion and along the sliding recess, to accommodate the backlight unit in the receiving space such that the inlet portion exposes a side portion of the accommodated backlight unit;

providing a side mold which covers the exposed side portion of the accommodated backlight unit; and

providing a display unit configured to receive the light to display an image, on an upper end of the mold frame.
