Abstract :
Among various semiconductor devices, electronically active oxide thin film transistors (TFTs) have received considerable attention for a wide range of device applications. Double metal-oxide thin film transistor (TFT) shows high photo current as Ilight/Idark >106, a mobility of >10cm2/Vs and high stability under LCD operation condition. In this paper, the possibility of a novel application of an optical touch screen which is entirely based on the metal oxide TFT is proposed.
