We have constructed a sheet-to-sheet (S2S) manufacturing line in order to prove the possibility and reality of production technologies and integrated processes of all-printed electronics devices[1,2,3]. In our automated and continuously operated manufacturing line, we operated the reverse offset printer for electrode pattern, digital inkjet printer for organic semiconductor layer, slit-die coater for insulator layer, and screen printer for electrode and inter-layer insulator. The average mobility of organic TFT is 0.7 cm2/Vs, average ON current is 5 uA with less than 10% sigma in A4 size area, and ON/OFF current ratio is ten of order 6. We have been acquiring successful results of TFT array flexible film in a reasonable high yield. These all-printed organic TFT array back-plane is applied to the flexible and light-weight pressure sensor which is driven in active matrix mode, and which is applied for a touch pad of writing with pressure grey scale or a commodity inventory system.
