Abstract:
A video-wall module is disclosed. In an embodiment a video-wall module includes a printed-circuit board, a plurality of light-emitting diode chips arranged at the printed-circuit board, a circuit chip fixed to the printed-circuit board, wherein the circuit chip is connected with electrical connections of the light-emitting diode chips in order to electrically actuate the light-emitting diode chips and a housing for the circuit chip at least partially formed by the printed circuit board, wherein the light-emitting diode chips are divided into a first area and a first edge area surrounding the first area, and wherein the light-emitting diode chips in the first area comprise a smaller radiation wavelength than the light-emitting diode chips in the first edge area on average at the same temperature.
