PHOLED

(PHosphorescent OLED) An OLED material that provides greater efficiency than conventional fluorescent OLEDs. With its UniversalPHOLED brand of chemicals first commercially deployed in 2003, Universal Display Corporation (UDC) in Trenton, New Jersey is the leader in phosphorescent OLED technology.

PHOLED is a small molecule, non-polymeric technology that consumes less power than LCDs. Combined with the intense colors of OLED, PHOLEDs have helped OLED become the dominant display technology for the 21st century. See OLED.


PHOLED Layers
An OLED is a series of organic thin films sandwiched between two electrodes, all deposited onto a substrate. When electricity is applied, charge carriers (holes and electrons) are injected from the anode and cathode into the PHOLED layer and recombine to form excitons, which cause photons to emit.

In addition to development of the PHOLED technology itself, UDC is also working towards manufacturing solutions that will allow large-scale production at acceptable costs.
UDC's own statistics for its PHOLED technology show high luminous efficiencies, measured in candelas per amp, for such colors as greenish-yellows, dark reds, and a few other colors.
Although UDC stands alone in its use of PHOLED technology, it has plenty of competition from other companies.
Others have produced white OLEDs, including Philips Osram, Samsung SHI, Chimay Optoelectronics, and Konica-Minolta, which claimed to have created a 64 lm/W PHOLED. Because UDC is the primary technology developer of PHOLEDs, these companies are potential customers.
In my mind there is a whole spectrum of products" that benefit from OLED and PHOLED technology, says Mahon.
PHOLEDs are what sets UDC apart in the field of OLED technology.
