The UV Line for Solid State Laser Lift-Off (LLO) has been successfully used for years in the lift-off field of OLEDs in the production of flexible mobile phone displays. Thanks to their brilliant colors, OLEDs have conquered further fields of application, such as smartwatches, tablets, laptops, home theaters and especially the automotive industry (foldable displays, dashboard displays). In response to this trend, significant advances are being made in the industrial production of OLED displays of all sizes. In addition to simply scaling the display area and throughput, the need to boost productivity has also been identified. Focuslight's new beam shaping technology for UV lasers comes into play.

The development team at Focuslight has now enhanced the optical design far enough that the Gaussian profiles can be turned into a line with a length of up to 1,000 mm and a width of 30 µm. The new features include significantly steeper edges and a wider intensity maximum. This allows an increased productivity by more than 30%. In addition, the sensitive OLEDs are subjected to lower thermal loads (lower ash value), yields are higher, and the OLED displays produced have a longer lifespan.

For the laser lift-off process of displays, we offer UV-Lines with different line lengths from 100 to 1,000 mm. In addition to complete systems with long lines for integration into production, Focuslight also offers cost-effective systems with shorter lines, which can be used in advance in the process development.
