Powerlase applications engineering manager Paul Harrison is talking about that their Lasers cut cost of OLED production.

Sussex-based Powerlase is making lasers that are expected to have an impact on the production of OLEDs.

Laser annealing is used in Oled production to convert easily-deposited amorphous silicon into polysilicon which makes better transistors because carrier mobility is higher.

His argument is that OLEDs need better semiconductors because they are current driven and need five transistors per pixel, compared with LCDs that are voltage driven and have only one or two transistors per pixel.

The new facility is the third fully-owned international operation to be opened by Powerlase, following operations in the UK and Korea. Rapidly expanding markets, including photovoltaic (PV), solar cell and active-matrix organic light emitting diode (Amoled) displays, have made opening a local office in Japan an attractive prospect for the company. A number of Powerlase’s existing customers also maintain head offices and manufacturing operations in Japan.
