  • Direct conversion digital x-ray detector with inherent high voltage protection for static and dynamic imaging
    Patent number: 6353229
    Abstract: A direct conversion digital x-ray detector is provided with inherent high voltage protection for static and dynamic imaging. The detector has an n-channel active matrix TFT array, a coplanar photoconductor structure and a high voltage biasing electrode. In order to achieve high voltage protection, the biasing electrode is set to a negative potential and the TFT “off” gate voltage is set to a predetermined negative value, such that the TFT is essentially non-conductive.
