Abstract: The growing maturity of thin film transistor (TFT) technology coupled with newly emerging materials and processes are enabling integration of systems for a family of new applications ranging from active matrix OLED displays, and augmented human-machine interactivity, to sensing systems. In particular, the oxide semiconductor is becoming a key technology for these applications. It exhibits high transparency as well as high electron mobility at low fabrication temperature. This paper will discuss the development of oxide TFTs for displays, including interactivity, and present a contrasting study with LTPS backplanes from the standpoint of system design and compensation techniques for VT instability and OLED degradation. Besides pixel circuits and display systems, TFT-based analog and digital circuitry for signal processing and wireless power transmission are required for realization of heterogeneously integrated systems that can be realized using a combination of oxide and other technological routes on disposable/recyclable substrates. Such systems place great demand for expedient CAD tools to accurately and to reliably predict system behaviour. We review physically based CAD models, taking into account the relative dominance of the carrier transport mechanisms in the TFT, along with circuit examples.
