80‐2: A High‐Resolution In‐Cell Fingerprint Display with New Isolation Structure

A new isolation structure was developed without increasing the number of photolithography process for suppressing electrical crosstalk between OLED and organic photodiode (OPD) pixels, one of the biggest issues for high‐resolution in‐cell fingerprint sensing display. Using the isolation structure and highly efficient broadband OPD, we demonstrated a 6.2‐inch 360 ppi prototype and verified that FAR and FRR reached as low as 0.002% and 0.3%, respectively while the display performance remained excellent.
