Display device

1. A display device, comprising:

a display screen;

a reflective sheet disposed opposite the display screen and that reflects irradiated light toward the display screen;

a plurality of light emitters disposed at one side of the reflective sheet and that irradiates light to different reflective regions of the reflective sheet; and

a controller that adjusts a total amount of light generated in each of the light emitters,

wherein an entirety of a first reflective region that comprises all portions irradiated by a first light emitter of the plurality of light emitters is farther from the one side than an entirety of a second reflective region that comprises all portions irradiated by a second light emitter adjacent to the first light emitter.

2. The display device according to claim 1 , wherein the reflective regions irradiated by the plurality of light emitters do not overlap each other.

3. The display device according to claim 1 , wherein the plurality of light emitters irradiates the light toward the reflective regions via a space without passing through a light guide plate.

4. The display device according to claim 3 , wherein the reflective sheet is inclined from the one side of the reflective sheet toward an opposite side of the reflective sheet to approach the display screen.

5. The display device according to claim 3 ,

wherein the reflective sheet is disposed along the display screen, and

wherein the reflective sheet comprises:

a main body that reflects light toward the display screen; and

a partition wall that defines the reflection regions and that extends from the main body towards the display screen and extends from the plurality of light emitters along an emission direction of the light.

6. The display device according to claim 1 , wherein the reflective regions are disposed in a grid pattern on the reflective sheet.

7. The display device according to claim 6 ,

wherein the display device comprises one or more sets of:

a first group of the reflective regions aligned in a first direction perpendicular to a second direction in which the plurality of light emitters is disposed along the one side of the reflective sheet; and

a second group of the light emitters that irradiates light to the first group of the reflective regions.

8. The display device according to claim 7 ,

wherein each of the light emitters comprises:

a light source that generates light; and

a lens that guides the light from the light source to the reflective sheet, and

wherein the plurality of light emitters varies a direction of light emission by respectively varying light distribution characteristics of the lens to the light source.

9. The display device according to claim 8 ,

a total number of the reflective regions included in the first group is equal to a total number of the light emitters included in the second group, and

the light emitters of the second group respectively irradiate different reflective regions of the first group.

10. The display device according to claim 7 ,

wherein each of the light emitters comprises:

a light source that generates light, and

a lens that guides the light from the light source to the reflective sheet, and

wherein the plurality of light emitters varies a direction of light emission by respectively varying installation angles of the light emitters.

11. The display device according to claim 7 , wherein each first group of the one or more sets is separated by a partition wall that extends from the reflective sheet towards the display screen and extends along a light emission direction of the plurality of light emitters.

12. The display device according to claim 1 , wherein the plurality of light emitters is aligned along the one side of the reflective sheet.

13. The display device according to claim 12 , wherein the plurality of light emitters irradiates light in a direction substantially parallel to the display screen.

14. The display device according to claim 12 ,

wherein each of the light emitters comprises:

a light source that generates light, and

a lens that guides the light from the light source to the reflective sheet, and

the lenses of the plurality of light emitters are integrated and connected to each other in a direction perpendicular to the display screen.

15. The display device according to claim 1 , further comprising another plurality of light emitters disposed at the opposite side of the reflective sheet.

16. The display device according to claim 15 , wherein the reflective sheet is inclined from both the one side and the opposite side of the reflective sheet toward a center of the reflective sheet to approach the display screen.
