P.23: Nano-Si Optical Pixel-Sensor Array using TFT Technology as Image-Scan/Fingerprint Panel

We report the controllable UV-Visible nano-Si photonic sensor, band-gap spectrum engineering, and integrated in TFT technology as Image-scan/Fingerprint panel. Photonic Sensor using nano-Si as sensitizer sandwiched between two electrodes structure is proposed to integrate optical input function for new application in next generation portable devices. The optical input function, used for image scanner, fingerprint recognition, and touch-input application, are achieved by integrating these image sensor elements within each pixel. A 1-transistor (1T) passive pixel sensor (PPS) is used to integrate a 250/500 ppi image sensor within a scan-input panel.
