New Jersey Patent of the Month – October 2021
Opto-electronics are electronic devices that source, detect, or control light. Some of these use organic materials – a trend on the rise in the industry. Organic materials in this case may be less expensive and offer greater flexibility than inorganic counterparts. Universal Display Corporation develops and manufactures organic LEDs (OLED). Recently, Universal Display has worked on developing a compound which acts to enhance phosphorescent organic LED (PHOLED) devices.
When these compounds are introduced, the PHOLED has enhanced performance in terms of increased device life time, increased efficiency, and lower operating voltage. A traditional OLED has an organic layer between an anode and a cathode. The OLED has a hole injection layer and a hole transport layer amongst other components. The compound is formulated with compounds such as Cmpd1 through Cmpd 149. When these compounds are inserted as a host results in lower voltage, higher luminance efficacy, and higher power efficacy. So the same device structure as seen in traditional OLED and PHOLED devices can benefit, creating more powerful and effective lights.
Are you developing new technology for an existing application? Did you know your development work could be eligible for the R&D Tax Credit and you can receive up to 14% back on your expenses? Even if your development isn’t successful your work may still qualify for R&D credits (i.e. you don’t need to have a patent to qualify). To find out more, please contact a Swanson Reed R&D Specialist today or check out our free online eligibility test.
