P‐170: Enhanced Performance of Organic Photodetector Through Metal Doping and Inkjet Printing for Sensor‐in‐Pixel Displays

We developed an inverted OPD by doping the hole‐blocking layer with metals, reducing leakage current and enhancing detection performance under reverse bias. IGZO‐doped devices exhibited the best leakage current suppression and specific detectivity. Inkjet printing was applied to achieve precise pixelation of the OPD layers, highlighting its potential for largearea, solution‐processed Sensor‐in‐Pixel displays. This work demonstrates the feasibility of OPD fabrication for wearable and security applications.
