Abstract :
In this paper, we propose a novel sensor architecture utilizing different oxide semiconductor transistors as both switch and sensor elements, which is promising to be integrated with pixel array in a flat panel display. In addition, our study presents the optimum active structure for a workable three-terminal photosensor and the operation principle of an oxide sensor TFT proposed in this article provides to realize high frame rate (>;150Hz) sensor array, which enables to solve intrinsically slow response issue of oxide-based photosensor.
