Abstract

A display device including a display panel which displays images, an intermediate frame on which the display panel is seated, a lower receptacle which includes a first receiving portion including a bottom plate and sidewalls, and a second receiving portion separate from the first receiving portion, and a light source unit which includes an alignment plate and a point light source mounted on the alignment plate. The light source unit contacts the sidewalls of the lower receptacle, and the first receiving portion is coupled with the intermediate frame.

Claims

1. A display device comprising:

an upper receptacle;

a display panel which displays images;

an intermediate frame on which the display panel is seated;

a light source unit which includes an alignment plate and a point light source which is mounted on a first surface of the alignment plate; and

a unitary indivisible lower receptacle which includes;

a bottom plate,

a sidewall extending from the bottom plate, and

a second hole disposed in the bottom plate, through which the alignment plate and the point light source of the light source unit pass in removable coupling of the light source unit with the unitary indivisible lower receptacle,

wherein

the second hole is a single continuous member extending parallel to a lengthwise direction of the sidewall,

the second hole has a first width and a second width taken in a same direction parallel to the bottom plate of the unitary indivisible lower receptacle, and

the first width of the second hole is equal to or greater than a thickness of the alignment plate, and the second width of the second hole is equal to or greater than the sum of the thickness of the alignment plate and the thickness of the point light source, the thicknesses taken perpendicular to the first surface of the alignment plate.

2. The display device of claim 1, wherein the alignment plate includes the first surface and a second surface opposing the first surface, and the sidewall includes an internal surface and an external surface, the second surface of the alignment plate and the internal surface of the sidewall contacting each other.

3. The display device of claim 1, wherein the sidewall further includes a fastening portion with which the light source unit is coupled to the unitary indivisible lower receptacle.

4. The display device of claim 1, wherein

the sidewall of the unitary indivisible lower receptacle further includes a first fastening portion, and the alignment plate of the light source unit includes a second fastening portion aligned with the first fastening portion;

and

a fixing member is engaged with the first and second fastening portions, such that the light source unit is removably coupled with the unitary indivisible lower receptacle solely by the fixing member being engaged with the aligned first fastening portion and second fastening portion.

7. The display device of claim 1, wherein the light source unit further includes a unitary indivisible support member on which the alignment plate is mounted, the support member being coupled directly with the unitary indivisible lower receptacle.

8. The display device of claim 7, wherein the support member includes a support plate and a support wall extending from the support plate.

9. The display device of claim 8, wherein the support member is coupled directly with the bottom plate of the unitary indivisible lower receptacle.

5. A display device comprising:

an upper receptacle;

a display panel which displays images;

an intermediate frame on which the display panel is seated;

a light source unit which includes an alignment plate and a point light source mounted on a first surface of the alignment plate; and

a unitary indivisible lower receptacle which includes;

a bottom plate,

a sidewall extending from the bottom plate,

a second hole disposed in the bottom plate, through which the alignment plate and the point light source of the light source unit pass in removable coupling of the light source unit with the unitary indivisible lower receptacle, and

the sidewall including a fastening portion with which the light source unit is removably coupled to the sidewall, the fastening portion exposing the light source unit to outside the unitary indivisible lower receptacle at the sidewall thereof,

wherein

the intermediate frame includes;

a first sidewall portion facing the sidewall of the unitary indivisible lower receptacle, and

a first cutting portion at which the light source unit is removably coupled to the sidewall of the unitary indivisible lower receptacle the first cutting portion being disposed in the first sidewall portion and aligned with the fastening portion,

wherein the light source unit exposed to outside the unitary indivisible lower receptacle by the fastening portion, is further exposed to outside the display device through the first cutting portion aligned with the fastening portion.

6. The display device of claim 5, wherein the upper receptacle includes:

a second sidewall portion facing the first sidewall portion of the intermediate frame, and

a second cutting portion disposed in the second sidewall portion to overlap with the first cutting portion,

wherein the light source unit further exposed to outside the display device through the first cutting portion aligned with the fastening portion is further exposed to the outside of the display device through the second cutting portion overlapping the first cutting portion.
