Adapting large-area flexible hybrid TFT/CMOS electronics and display technology to create an optical sensor array architecture

This work presents a hybrid TFT/CMOS circuit architecture that integrates a flexible thin-film transistor (TFT) active matrix optical sensor array with peripheral CMOS drive circuitry for optical image capture, combined with the development of a complete optical image acquisition system. This configuration was then used to capture optical test images from a representative flexible 128 column × 240 row TFT array of imaging pixels. Test results demonstrated the ability to capture full 12-bit grayscale optical images from the flexible sensor array.
