Abstract
A light-emitting module for displaying or projecting a video signal comprises at least one mirror mounted so as to be able to oscillate and at least one light-emitting element, which is directed onto the mirror and is controllable via an input, and a computation unit that is connected to the light-emitting element and is configured to output at least one sample value of the video signal, which sample value appears at the input of said computation unit at a first time within a period of the mirror, at its output as a sample value at a second time, which is different from the first, within the same period according to a mapping function that is stored in the computation unit, wherein the computation unit has a control input that can be used to scale and/or offset the stored mapping function. The invention further comprises a display or projection apparatus having a multiplicity of such light-emitting modules, and a method for calibrating the light-emitting module and the apparatus.
