Abstract
A beam shaper is implemented to seal an OLED. The beam shaper comprises a first and second lens and a beam shaper. Changing the relative position of the first, second lens and beam shaper relative to each other enables the beam shaper to generate laser beams with different shapes and intensity profiles.
