Patent ID: 7932113

Claim:
A method of fabricating an organic light emitting diode (OLED) display provided with a plurality of pixels where OLEDs are formed respectively, the method comprising: sequentially forming a thin film transistor (TFT) array, first electrodes, and a first related layer on a first substrate; respectively forming heat-generating elements at positions on a second substrate, corresponding to red pixels on the first substrate, and at positions on a third substrate, corresponding to green pixels on the first substrate; forming a red organic emission pattern on the second substrate provided with heat-generating elements, and forming a green organic emission pattern on the third substrate provided with the heat-generating elements; aligning and attaching the first and second substrates, and thereafter applying a voltage to the heat-generating elements on the second substrate to transfer the red organic emission pattern to red pixel regions on the first substrate, thereby forming red organic emission layers at one time; aligning and attaching the first and third substrates, and thereafter applying a voltage to the heat-generating elements on the third substrate to transfer the green organic emission pattern to green pixel regions on the first substrate, thereby forming green organic emission layers at one time; entirely depositing a blue organic emission material on the first substrate provided with the red organic emission layers and the green organic emission layers, thereby forming a blue organic emission layer; and sequentially forming a second related layer and a second electrode on the first substrate provided with the blue organic emission layer.
