Abstract: A method for operating a visual display apparatus is specified. The apparatus comprises a first optoelectronic semiconductor component configured to emit electromagnetic radiation of a first wavelength and comprising a first intrinsic switch-on delay. The apparatus comprises a second optoelectronic semiconductor component configured to emit electromagnetic radiation of a second wavelength and comprising a second intrinsic switch-on delay. The second wavelength is different from the first wavelength. The first semiconductor component is operated with a first operating current according to a first actuation signal. The second semiconductor component is operated with a second operating current according to a second actuation signal. The first and/or the second actuation signal comprise a delay clock signal selected such that emissions of electromagnetic radiation from the first and second semiconductor components comprise a switch-on delay with respect to each other that is smaller than a difference of the first and second intrinsic switch-on delays.
