More info on Polymertronics' OLED plaster

Last week we reported on Polymertronics - a new company that's working on an OLED plaster to cure skin related diseases. Now we have some more information and a nice new photo.

Polymertronics are making their own Small-Molecule OLED materials, called OLED Red Diamond. One of the formulation can actually be printed via inkjet, and is also UV curable. That version is cross-linkable polymer.

Their idea is to use an array of OLEDs, each less than 1x1cm. Using many small OLEDs they can profile the light pattern across the skin cancer lesion. It also enables them to electronically monitor the performance of the device for short circuits, open circuits and aging segments. This is useful if the light-plaster is going to automatically manage the entire treatment once stuck onto the patient's skin.

They acknowledge the fact that using an array of OLEDs, rather than a single large one is more complex, but they say it does have a number of benefits.

Polymertronics are also working on the electronic interface of the OLEDs, and claim to icnrease the lifetime of the OLEDs by several orders of magniturde using a 'clever design'.

Lumicure, the 2nd UK company working on a similar device, is using one 'large' OLED panel.
