12‐2: Ultra‐High‐Resolution Active‐Matrix NanoLED Microdisplay by UV Photolithography

We report and discuss the challenges to realize ultra‐highresolution NanoLED on Si CMOS backplane. Quantum dot layers are patterned side‐by‐side by UV photolithography. We demonstrate a full‐color 1.03 inch active‐matrix NanoLED microdisplay with pixel density of 3,528 ppi and a wide color gamut over 120 % as a ratio to DCI‐P3. This is the world's highest resolution self‐emitting active‐matrix device created by patterning red, green, and blue quantum dots.
