New laser method ensures less expensive displays


Powerlase Ltd. of Crawley in the UK, has announced the development of the 400G laser for use in the green laser annealing (GLA) fabrication method, to create active matrix organic light-emitting diode (AMOLED) display screens and televisions.

The GLA process is being developed largely to replace an older and more expensive form of manufacturing, excimer laser annealing (ELA). Improvements in line consistency are also cited.

The GLA process should streamline the manufacturing process to lower the cost of screen production and ultimately the cost of the end display product.

Powerlase Ltd. is a manufacturer of nanosecond, Q-switched, diode-pumped, solid state (DPSS) lasers and this development is seen as a big breakthrough. Use of the 400G laser in AMOLED screen manufacturing looks set to reduce production costs, ensuring that the more environmentally friendly AMOLED screens are more affordable to businesses and consumers.
