Abstract

Disclosed herein are a display device, a display system and method thereof. The display device includes a display panel, a light emitter configured to emit light to display an image on the display panel, a pipe positioned adjacent to the light emitter and having a conductive fluid and a gas therein, and electrodes provided in the pipe and polarized, where heat is generated to move the conductive fluid inside the pipe when the light emitter emits light, and electricity is generated while moving and passing around the electrodes.

First claim

What is claimed is:

1. A display device comprising:
a display panel;

a pipe positioned adjacent to the light emitter, the pipe having a conductive fluid and a gas therein;
electrodes provided in the pipe, the electrodes being polarized; and
an energy storage portion configured to store electrical energy generated in the pipe,
wherein heat is generated to move the conductive fluid inside the pipe when the light emitter emits light, and electricity is generated while the conductive fluid and the gas move inside the pipe in which the electrodes are provided.

2. The display device of claim 1 , further comprising:
a main body; and
a bottom chassis configured to form a rear surface of the main body,
wherein the pipe is positioned between the light emitter and the bottom chassis.

3. The display device of claim 1 , wherein the pipe is formed in a form of a closed circuit pipe, and the conductive fluid and the gas circulate in the pipe when heat is transferred from the light emitter.

4. The display device of claim 1 , wherein the pipe includes:
an evaporator in contact with the light emitter;
an electricity generator on which the electrodes are formed; and
a condenser.

5. The display device of claim 1 , wherein an inside of the pipe is in a vacuum state.

6. The display device of claim 1 , wherein the pipe is formed of an insulating material.

7. The display device of claim 1 , wherein the pipe is formed in a form of a closed loop of any one of a spiral, a polygon, a circle, a zigzag, or a combination thereof.

8. The display device of claim 1 , wherein the pipe has a cross section in a circular or polygonal shape.

9. The display device of claim 1 , wherein the light emitter includes a light emitting diode or an organic light emitting diode.

10. The display device of claim 1 , wherein the conductive fluid and the gas have flow speeds controlled by adjusting a temperature of the light emitter.

11. The display device of claim 1 , wherein the gas is formed in a form of a bubble.

12. The display device of claim 1 , wherein the energy storage portion includes a power circuit, a super capacitor, or a battery.

13. The display device of claim 1 , wherein the electrical energy is used to drive the display device in a standby power mode.

14. The display device of claim 2 , wherein a coupling groove is formed in the bottom chassis such that the pipe is accommodated on a surface of the bottom chassis which is in contact with the pipe.

15. The display device of claim 4 , further comprising
a main body,
wherein, when the light emitter includes a plurality of light emitters and the pipe includes a plurality of pipes, the plurality of light emitters are formed at each of both side surfaces of the main body, the plurality of pipes are positioned to match each of the plurality of light emitters of the both side surfaces of the main body, and the evaporator is adjacent to the plurality of light emitters.

16. The display device of claim 4 , further comprising:
a main body,
wherein, when the light emitter is formed on one or the other side surface of the main body, the pipe is positioned so that the evaporator is adjacent to the light emitter formed on the one or the other side surface of the main body.

17. The display device of claim 4 , further comprising a main body,
wherein, when the light emitter includes a plurality of light emitters and the pipe includes a plurality of pipes, the plurality of light emitters are disposed on a front surface of the main body in a form of a plurality of rows, and the plurality of pipes are positioned so that the evaporator is adjacent to each of the plurality of light emitters disposed in the form of the plurality of rows.

18. The display device of claim 16 , wherein the pipe is formed to have a size which covers a front surface of the main body or a size which covers a part of the front surface of the main body.

19. A display system comprising:
a display panel;
a light emitter configured to emit light to display an image on the display panel;
a pipe positioned adjacent to the light emitter and having a conductive fluid and a gas therein;
electrodes provided in the pipe, the electrodes being polarized;
an energy storage portion configured to store electrical energy; and
a processor configured to store the electricity in the energy storage portion,
wherein heat is generated to move the conductive fluid inside the pipe when the light emitter emits light and electricity is generated while the conductive fluid and the gas move inside the pipe in which the electrodes are provided.

20. The display system of claim 19 , wherein the energy storage portion includes a power circuit, a super capacitor, or a battery.
