2. The electronic device of claim 1 , wherein the heat generating device includes a processor, and the processor is in direct contact with the heat spreading device.

3. The electronic device of claim 2 , wherein the heat generating device includes a circuit board, and the processor is attached to the circuit board.

4. The electronic device of claim 1 , wherein the heat spreading device includes a vapor chamber having a first surface and a second surface, and the heat generating device is in contact with the second surface of the vapor chamber.

5. An electronic device comprising:
an organic light emitting display (OLED); and
a heat generating device to provide signals to the OLED; and
a heat spreading device between the OLED and the heat generating device, the heat generating device being in direct contact with the heat spreading device, and the heat spreading device being configured to dissipate heat generated by the heat generating device;
wherein the heat spreading device includes a vapor chamber having a first surface and a second surface, and the heat generating device is in contact with the second surface of the vapor chamber;
wherein the heat spreading device includes a heat sink having a first surface, a second surface, and a plurality of fins that extend from the first surface of the heat sink toward the OLED.

6. The electronic device of claim 5 , wherein the second surface of the heat sink directly contacts the first surface of the vapor chamber.

7. The electronic device of claim 5 , wherein the plurality of fins are in direct contact with the OLED.

8. The electronic device of claim 1 , wherein the heat spreading device includes a heat pipe structure having a first surface, a second surface and a plurality of heat pipes at the second surface of the heat pipe structure, and the heat generating device contacts the second surface of the heat pipe structure.

9. An electronic device comprising:
an organic light emitting display (OLED); and
a heat generating device to provide signals to the OLED; and
a heat spreading device between the OLED and the heat generating device, the heat generating device being in direct contact with the heat spreading device, and the heat spreading device being configured to dissipate heat generated by the heat generating device;
wherein the heat spreading device includes a heat pipe structure having a first surface, a second surface and a plurality of heat pipes at the second surface of the heat pipe structure, and the heat generating device is in contact with the second surface of the heat pipe structure;
wherein the heat spreading device includes a heat sink having a first surface, a second surface, and a plurality of fins that extend from the first surface of the heat sink toward the OLED.

10. The electronic device of claim 9 , wherein the second surface of the heat sink directly contacts the first surface of the heat pipe structure.
