Abstract
An optical projection device and a method of producing the optical projection device are described. The optical projection device includes: a plurality of LEDs (light-emitting diodes), the LEDs each including a semiconductor mesa laterally spaced apart from one another by a grid structure. Each of the semiconductor mesas includes an n-type material and a p-type material adjoining at least partly the n-type material. The grid structure at least partly laterally surrounds at least the n-type material of each of the semiconductor mesas. The grid structure includes a conductive material that electrically interconnects the n-type material of the semiconductor mesas. The grid structure is configured to block optical crosstalk between light emitted by the LEDs.
