Abstract

A flat panel display apparatus includes a display unit for displaying images, a first semiconductor and a second semiconductor electrically connected to the display unit, and a heat sink electrically connected to the first semiconductor and to the second semiconductor.

Claims

1. A flat panel display apparatus comprising:

a display unit for displaying images;

a first semiconductor and a second semiconductor electrically connected to the display unit; and

a heat sink electrically connected to the first semiconductor and to the second semiconductor.

2. The flat panel display apparatus of claim 1, wherein the heat sink is opposite to the display unit.

3. The flat panel display apparatus of claim 1, wherein the heat sink dissipates heat generated by the display unit away from the display unit.

4. The flat panel display apparatus of claim 1, wherein light generated by the display unit is emitted in a direction away from the heat sink.

5. The flat panel display apparatus of claim 1, wherein the first semiconductor is a P-type semiconductor and the second semiconductor is an N-type semiconductor.
