Full color 2.2‐inch Quarter Common Intermediate Format (QCIF) organic EL displays were developed using phosphorescent materials and low temperature poly‐Si (LTPS) technology. These displays exhibited a world record efficiency of 11cd/A at an optimized white CIE coordinate of (0.31, 0.32) with an OLED operating voltage of 6V. The current pixel structure for the 2.2‐inch display allows about 32% aperture ratios and a white peak luminance of over 300cd/m 2 .
