Excimer Laser Annealing System for High-resolution Panels

Excimer Laser Annealing (ELA) system converts amorphous silicon layer on a glass substrate to poly-silicon one, which is generally used in TFT (Thin Flat Transistor) of the high-resolution panels. ELA System is essential for the production of high-resolution panels, such as smartphones, digital cameras and portable gaming devices.


Sales Records

Since 1995, we have sold over 200 systems to display companies in Japan, South Korea, Taiwan, China and Singapore, as one of the top manufacturers of ELA system.
