Abstract

An opto-electronic indicating matrix comprises a plurality of row and column segments controllable in a multiplex operation, and means for electrically connecting the row and column segments and including a plurality of conductors arranged in regions between the row segments and inclined to a longitudinal axis of the row axis so as to extend parallel to one another in one plane. A preferable application of the matrix is in an indicator for travel guiding information in a power vehicle.
