Abstract: The invention relates to a laser projection arrangement. The arrangement includes a sub-mount carrier with a main surface and at least one edge-emitting laser arranged on the sub-mount. The at least one edge-emitting laser is facing the sub-mount and includes at least one laser facet that is located at a predefined distance from the main surface of the sub-mount. A planar light circuit with at least one light guide has an inlet and is arranged on the sub-mount such that the at least one light guide and the inlet is located at the predefined distance from the main surface of the sub-mount facing the at least one laser facet.

Abstract: A light emitting cell for use as a pixel, the light emitting cell being configured to generate the three primary colors and to form different color tones therewith, comprising: a light emitting front surface, a rear surface, and a substrate arranged between the front and rear surface; a light source carried by the substrate; three luminous sections, comprising a blue luminous section, a light converting red luminous section, and a light converting green luminous section; and a primary color selection device capable of performing a repetitive movement at a certain frequency so that, during this movement, one of the luminous sections is alternately selected as a potential light emitting section, characterized in that the primary color selection device is a single mechanical component that serves to select all three luminous sections.
