[LG Chem’s OLED panel for lighting on display]

At the exhibition, LG Chem showcased 4 types of OLED lighting of 50x70,mm 150x20mm, 150x30mm, and 150x150mm in size. The products used UDC’s green and red phosphorescent materials and blue fluorescent material. The blue fluorescent material is the deep blue material which is being used in display. The basic structure of LG Chem’s OLED lighting device is Anode-Blue-Intermediate Layer (using LG 101 materials)-Green&Red-Cathode, and the panels displayed at the exhibition in the form of Piet Mondrian’s picture provide various color temperatures, which was realized by adjusting the thickness of materials and changing the laminar structure.

The displayed OLED panels for lighting are cool white OLED which provides 20-25lm/W at 2000nit (equivalent to 30-37lm/W at 3000nit when lighting extraction is factored in) and the color temperature of 5000-6800K.

LG Chem plans to mass produce OLED lighting in 2011 and to this end, it is now developing relevant equipment with an equipment maker. LG Chem currently has 200x200 deposition equipment and pre-process equipment.
