Patent ID: 7183700

Claim:
An organic light emitting diode (OLED) display comprising: a substrate, a plurality of pixel areas being defined on the substrate; a heating circuit structure comprising: a first conductive line and a second conductive line not connected to each other formed on the substrate; a first isolation layer formed on the substrate, the first isolation layer comprising a plurality of first contact holes exposing the first conductive line and the second conductive line; a plurality of first heating wires and a plurality of second heating wires disposed on the substrate, each of the first heating wires and each of the second heating wires being electrically connected to the first conductive line and the second conductive line respectively through each of the first contact holes and covering portions of each of the pixel areas; and a ground electrode being electrically connected to each of the first heating wires and each of the second heating wires; and a plurality of organic light emitting diodes corresponding to each of the pixel areas.
