No new defects appear on the display after 100,000 times bending with radius of curvature at 3 mm. In the oxide TFT, the Lanthanide rare earth doped In-Zn-O (LnIZO) is employed as the key active layer to improve the mobility and stability. The fabricated Ln-IZO TFT with BCE process exhibits a high field-effect mobility of ～40 cm~2 V~(-1) s~(-1), a subthreshold swing of 0.13 V/decade, and an I_(on)/I_(off) ratio of 10~9. Meanwhile, laminated Al_2O_3/MgO film prepared by the method of atomic layer deposition (ALD) is used as the encapsulation of AMOLED display. 收起
