We have succeeded in developing the highest resolution full‐color polymer OLED display to date. A newly developed, original ink‐jet patterning system for OLEDs combined with an optimized ink material and OLED fabrication process have achieved a uniform polymer thin film on a special substrate. The OLEDs, driven by low temperature poly‐Si TFTs, offer 6‐bit full‐color for each color. Consequently, they enabled us to produce a display having uniform emission over a 2.1‐inch diagonal display area, excellent color reproduction quality, and a sharp, clear image.
