LG Chem announced today that it achieved two important milestones in the development of OLED lighting products with the start of manufacturing of the 320 x 320 mm OLED light panel, the world’s largest available in the market, and the completion of the research and development phase for a new plastic-based OLED light panel.
The 320x320mm OLED light panel is 0.88mm thick panel and has an efficiency of 60lm/W, CRI over 90, and has output levels of 800lm with a nominal input (8.5V 1,600mA). The panel’s output can reach 1,200lm which is similar to a common 60-75 Watt incandescent lamp. This is significant because it marks first time that OLEDs can be considered as an energy-efficient / human-friendly light source available for general purpose use.
With LG Chem having begun mass producing the 320x320mm panels in January, the panels can be ordered at $680USD per panel, with a lower negotiated price for bulk orders.
LG Chem has also completed development of a truly flexible plastic-based OLED light panel and engineering samples are now available. LG Chem’s current bendable OLED panels (F6BA40, F6BA30) are thin-glass based that provides a limited bending radius of 75mm. The new flexible OLED panel has vastly increased the bending radius flexibility to 30mm because of the adoption of a plastic substrate for the panel, which also eliminates the danger of the panel shattering when excessive force is applied.
The main challenge of converting from a glass substrate to plastic was to maintain the performance levels of efficiency, luminance, and CRI. LG Chem has overcome this challenge by adopting its expertise in barrier and encapsulation technology.
The specifications of the LG Chem’s new plastic-based OLED light panel are 60lm/W efficiency, 75lm brightness, 3,000K in color temperature, and CRI over 85. Engineering samples are available at $250USD per panel. The mass production of the flexible panel is scheduled to begin in July 2015. The price will be adjusted accordingly once mass production starts.
