Powerlase has developed the 400G laser for Green Laser Annealing (GLA) in Active Matrix Organic Light Emitting Diode (AMOLED) screen manufacture.
The laser products developed by Powerlase are designed in line with specific customer requirements. The 400G has been developed and tested in cooperation with one of the leading display screen manufacturers and is now entering the final development phase before being implemented in high volume manufacturing facilities.
Many companies are developing the GLA process to improve line consistency, which is the problem with conventional ELA (Excimer Laser Annealing) solutions. The GLA process creates long crystals of polysilicon, which are required to provide the required levels of picture performance. This innovation in the production of screens is reflected in the dropping price of AMOLED displays, meaning this greener, high performance display technology is more widely available.
The Starlase 400G (400W at 532nm) DPSS laser will be required for production in order to achieve the required throughput. The 400G product is the most powerful diode-pumped, solid-state green laser currently available.
