Patent ID: 7790526

Claim:
A method of fabricating a system for displaying images, wherein the system comprising an active matrix organic electroluminescent device, the method comprising: providing a substrate having a switching thin film transistor region, a driving thin film transistor region, and a storage capacitor region; forming a first conductive layer within the switching thin film transistor region, a first gate electrode within the driving thin film transistor region, and a lower first electrode within the storage capacitor region; forming a first dielectric layer on the substrate to cover the first conductive layer, the lower first electrode, and the first gate electrode; forming a first poly island on the first dielectric layer within the switching thin film transistor region, a second poly island on the first dielectric layer within the driving thin film transistor region, and a third poly island on the first dielectric layer within the storage capacitor region; performing a doping process to the third poly island to form a second electrode; forming a second dielectric layer on the substrate to cover the poly islands and the second electrode; forming a second gate electrode on the second dielectric layer over the first poly island, a higher first electrode on the second dielectric layer over a part of the second electrode, a second conductive layer on the second dielectric layer over the second poly island; forming first source and drain regions in the first poly island to define a first channel region located between the first source and drain regions, and second source and drain regions in the second poly island to define a second channel region located between the second source and drain regions; forming a passivation layer on the substrate; forming a first contact to contact the second drain region; and forming a pixel electrode to electrically connect to the second drain region via the first contact; forming a second contact to electrically connect the second electrode and the second source region; and forming a third contact to electrically connect the first source and drain regions, the lower first electrode, and the high first electrode.
