Abstract: Patterning an organic light emitting diode (OLED) after it has been encapsulated by permanently changing the light emissivity of the diodes. The OLED includes an intervening layer providing a pressure sensitive touch panel or touch screen panel. Depending on the composition of the light emitting layer, the laser treatment will enhance or diminish brightness.

Abstract: Disclosed herein are methods of laser patterning organic light emitting diodes by permanently changing the light emissivity of the diodes.

Abstract: A laser imaging system for direct imaging with high optical power density a series of pixels forming an image on a media surface, The laser imaging system includes a laser light source, wherein the laser light source emits a laser beam representative of the image on the media surface. An optical path is defined between the laser light source and the media surface. A scanner is provided having a mirrored surface positioned along the optical path. An optical assembly is positioned along the optical path for shaping and focusing the laser beam at the media surface, including an F-Theta lens assembly positioned along the optical path between the scanner and the media surface. The F-Theta lens assembly includes a spheric lens, an aspheric lens and a toric lens, providing an increase in optical power density at the media surface.
