This study proposes a 3D integration architecture using top-gate organic thin-film transistors (OTFT) as pixel switches and bottom-gate organic phototransistors (OPT) for photo-sensing in each pixel. Through low-temperature solution-based integration processes on plastic substrate, a flexible active-matrix imager with high resolution is successfully implemented.
A three-dimensional (3D) integration architecture composed of a top-gate organic thin-film transistor (OTFT) as pixel switch and a bottom-gate organic phototransistor (OPT) for photo-sensing is proposed to construct flexible active-matrix optical imager. The two devices in one pixel can be separately optimized for functions of pixel switching and photo-sensing, respectively. Low temperature (< 150 degrees) solution-based integration processes are developed to achieve high-resolution 3D stacking on plastic substrate. A flexible active-matrix imager of 100x100 pixels (127 ppi) is implemented based on such integration architecture, and demonstrated for fingerprint imaging under ambient light condition.
