Different types of ultraviolet photodetectors and their suitability for active-matrix sensing are discussed. Phototransistors are compared to photoconductors in terms of sensitivity, efficiency and response time. The photosensor readout is implemented by a transimpedance amplifier consisting of a-IGZO TFTs. Measurements with a 64-pixel array are shown to illustrate the applications.
