SUMMARY / OUTLOOK
Lasers play a key-role in today’s display manufacturing and enabled the trend towards highest ppi flexible OLED displays. Lasers support future trends, bringing 8k-TV and Large Size
OLED screens to the consumer. Lasers are working at the forefront of new display technologies. Lasers can eliminate wet processing to support
initiatives towards zero liquid emission factories.
