BASF has announced that Company researchers have succeeded in improving the composition of the individual semiconductor ink components to double the mobility of the charge carriers in the printed circuits.|
According to BASF the mobility of the charge carriers is an important criterion and is decisive for the use of the semiconductor inks in a range of applications. This recent development is expected to further reduce the size of transistors and enable higher resolution LCD or OLED screens on plastic substrates to be manufactured.
BASF added that their new printable semiconductor inks and new process technologies open up a range of options for designers. For example, new, flexible substrate materials. The combination of printability and high mobility will enable all conventional display technologies (ePaper, LCD, OLED) to be equipped with printed backplanes. This makes flexible displays easier to manufacture.
Further applications include organic circuits and organic memories for intelligent packaging through which the consumer can, for example, obtain additional information about the packaged products, as well as portable electronics (wearables) such as fitness wristbands or smartwatches.
No other details of the performance of these materials where provided.
Dr. Heike Pfistner, Marketing Organic Electronics at BASF New Business, said, "Because of their technical properties, the semiconductor inks we have offered so far have already proved successful in our customers' applications." Heike added, "We are continuously optimizing the products from our portfolio and can now offer printable semiconductors with significantly better performance and with the usual good processability."
