A method of making a current type active matrix OLED device, includes
providing a semiconductor layer, a conductive layer, and an insulator
layer therebetween over a substrate, providing an organic light emitting
diode over either the semiconductor layer or over the conductive layer
for each pixel, and forming a first transistor having a channel region
formed in the semiconductor layer and a gate formed in the conductive
layer for each pixel for receiving a first current data signal for
adjusting the emission brightness in its corresponding pixel. The method
also includes forming a second transistor for each pixel for regulating
current through the organic light emitting diode in response to the first
current wherein each second transistor has a gate formed in the
conductive layer and a channel region formed in the semiconductor layer,
and annealing particular regions of the semiconductor layer by using a
pulsed laser.
