Abstract
An optoelectronic light emitting device includes a plurality of programmable pixels arranged in a matrix of rows and columns, each pixel including at least one optoelectronic semiconductor component, and programming device configured to program the pixels in a plurality of successive time intervals. A row pattern including a subset of the rows of the matrix is given. The programming device is configured to program the pixels of those rows per time interval which are comprised by the row pattern. The row pattern is shifted by at least one row per time interval.
