Abstract
Methods and displays utilize row and column drivers with ZnO channels that control pixel transistors with ZnO channels, which in turn address OLEDs of an array to produce images of a display screen. A display backplane including the ZnO row and column drivers and the OLEDs may be constructed by utilizing aperture masking or a combination of photolithography and aperture masking. Monolithic integration of the ZnO row and column drivers together with the ZnO pixel transistors is thereby achieved.
