Elektrolumineszenzelement und Verfahren zu dessen Herstellung

摘要

The invention relates to the manufacture of electroluminescent elements on the basis of a so-called planar electrode arrangement (8a, 8b), whereby the modifications in accordance with the invention enable a substantial increase of the luminous power to be attained. To strengthen the electric field and hence increase the brightness, a special multilayer technology is employed. The electric field may be further strengthened by a film having a high dielectric constant. Preferably, a customary printed circuit board is used as the supporting board, so that the process in which the electroluminescent element is manufactured can be directly integrated in the printed- circuit-board manufacturing process. A further advantage of the invention is that the printed circuit boards provided with the optical components in accordance with the invention can be soldered by means of customary solder processes.
