    摘要: The invention relates to light emitting semi-conductor components, in which the individual chips are located at the cross-points between two mutually vertically oriented systems of parallel conducting paths, so that line- or matrix forms are created. Such components are used to produce electro-optical exhibits of numbers, letters or symbols, for instance, in the optical exhibit of recorded material.The invention employs only one supporting substrate with recesses for the semi-conductor light emitter chips and for the distribution of light as well, with at least one conducting path system, which is connected by means of conducting and non-conducting adhesives on the viewing side to a diffusion film, and on the backside to a flexible, conducting plate, which supports the semi-conductor chips.
