In order to meet the requirements of novel display technologies such as high-resolution large-screen LCD and AMOLED,a novel active-matrix panel is developed. This novel active-matrix panel is based on the metal oxide thin film transistor ( MOTFT) with metal oxide semiconductor materials as the active layer. In this paper,the material,the structure of the device,the fabrication process and the application of MOTFT are expounded,and the factors that influence the MOTFT performance are discussed. Moreover,the relevant research results achieved by the research team are presented as follows: ( 1) the MOTFT reaches a mobility of 21. 6 cm² /Vs at its highest,with a threshold voltage of 1. 63 V,a current on /off ratio of 10⁹,and a sub-threshold swing of 0. 216 V/decade; ( 2) based on the MOTFT panel,the first 5-inch color AMOLED screen in China is developed; and ( 3) the MOTFT panel has the advantages of high mobility,simple fabrication process,and lower cost as well as greater ease in achieving large screen display. Therefore,it has wide application prospects in developing novel display technologies such as TFT-LCD and AMOLED.
