General Electric Global Research has achieved a major breakthrough, developing a fully functional 2 ft. x 2 ft. light panel that produces more than 1200 lumens of quality white light with an efficacy of 15 lumens per watt. This device offers 50% better energy performance than their previous device, breaking two world records.
In the second year, GE focused on developing a new scalable, fault tolerant architecture compatible with low-cost fabrication methods. The result was a device measuring 6 in. x 6 in. that produced 70 lumens of light with an efficacy of 7 lumens per watt — another world record. In the third and final year, the team focused on increasing lumen output and efficiency, developing a 2 ft. x 2 ft. illumination-quality OLED array using a tiling approach to link 16 panels together.
These breakthroughs demonstrate that the light quality, output, and efficiency of OLED technology can meet the needs of general illumination. The next goal is to demonstrate that organic electronic devices can be made cost-effectively on flexible material in a continuous roll-to-roll process.
