LG Chem Ltd. and Universal Display Corp. have announced that they have signed a non-exclusive joint development agreement to accelerate the commercialization of high-performance OLED materials for use in OLED displays and lighting products. The collaboration will focus on combining LG Chems electron transport and hole injection materials with Universal Displays phosphorescent OLED emitter materials and technology.

Universal Displays proprietary PHOLED technology offers up to four times higher efficiency than conventional OLED technology - a feature that is very important for todays battery-operated cell phones and other portable devices, as well as for tomorrows large-area TVs and solid-state lighting products.

LG Chem has developed OLED transport materials that lead to reduced operating voltage. By combining LG Chems transport materials with Universal Displays PHOLED emitters, high efficiency as well as low voltage can be achieved.

Based on previous work with LG Chem materials, Universal Display has demonstrated a red PHOLED device with a luminous efficiency of 17 cd/A, an operating voltage of 4.8 V and an operating lifetime of 150,000 hours to 50% of initial luminance (at 1,000 nits) and a green PHOLED with 64 cd/A, 3.9 V and 250,000 hours (at 1,000 nits). Through this new agreement, the companies plan to accelerate their collaboration to combine and optimize higher performance materials for OLED device manufacturers.
