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/m2.

Liquid crystal molecules with a new fluoro‐isothiocyanate moiety were synthesized. They showed remarkably high TNI (>190 °C), wide mesophase range of 170 °C, high dielectric anisotropy (>14) and high optical anisotropy (>0.28). New LC Mixtures of the high TNI (>85 °C) was blended with the novel fluoroisothiocyanate containing LC molecules, phenylcyclohexanes, bicyclohexanes and ester compounds. The LC mixtures show a fast speed (<10ms) of the below one frame rate in 17″ WXGA panel.
