A high resolution (2 inch, 80 dpi) organic thin‐film transistor driven light‐emitting diode has been developed on plastic substrate. The pentacene OTFT array was fabricated using self‐organized process. The TFT in the array exhibited an average field‐effect mobility of ∼1 cm 2 /Vs, an on/off current ratio of 10 7 , and a threshold voltage of ∼ −8 V after the bank formation with parylene‐C / SiN x , which is good enough to drive OLEDs. An AMOLED was driven in the bent state of 100 mm radius.
