Ultra-High-Resolution Active-Matrix NanoLED Microdisplay by UV Photolithography

Description:

We report and discuss the challenges to realize ultra-high-resolution 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.
