ABSTRACT:
A method for manufacturing an LED display means, whereby a plurality of LED chips are arranged on a system carrier composed of interconnects and the LED chips are individually respectively embedded in a light-guiding channel composed of a transparent plastic allocated thereto and having a light exit window. The method enables the realization of surface-mountable LED displays that can be flow-soldered. The specifically designed system carrier is equipped with sealing and supporting webs and those locations provided with the LED chips are enveloped with a diffusely scattering, transparent plastic for the formation of mutually separated light-guiding channels. After solidification of the plastic, the sealing and supporting webs in the inside of the system carrier are removed in a first punch-free process and the light-guiding channels and the inside regions of the system carriers surrounding light-guiding channels are then provided with a reflective envelope. The method is employed in the manufacture of LED displays and LED symbol lamps.
