HAMBURG, Germany, April 1, 2010 — LEDs are expected to develop into one of the predominant light sources over the coming decades. However, the pace of development differs, depending on specific requirements and constraints. One promising market today is display backlight technology. Experts forecast quadrupling of the number of LCD displays with LED backlighting in 2010, superseding conventional cold-cathode fluorescent lamps. Laser marking is an essential step in manufacturing the required LEDs. Dashboard lighting with LEDs.

    laser marking
    Laser marking is a process in which a laser beam is used to mark or engrave a surface by altering its properties or appearance. This technique is widely used for labeling, identification, and decoration of various materials, including metals, plastics, ceramics, glass, and more. Laser marking provides a permanent and high-precision method for adding information or graphics to a wide range of objects. Key features of laser marking include: Contactless process: Laser marking is a non-contact...
