Here, an entirely printed passive matrix image detector composed of 256 individual pixels with an individual active area of ≈250 µm × 300 µm is fabricated. The fabrication of the organic photodetector (OPD) array is enabled by exploiting a self‐alignment process of the functional layers induced by digitally printed dewetting patterns resulting in high‐performance reproducibility and fabrication yields of 100%. The single OPD pixels fabricated under ambient conditions exhibit state‐of‐the art performances with spectral responsivities of up to 0.3 A W −1 , a linear dynamic range of 114 dB, and calculated specific detectivities ( D* ) > 10 12 Jones, thereby, competing with performances of current inorganic devices.
