| abstract | The invention relates to a light-emitting device comprising at least one light-emitting diode stack (1), said light-emitting diode stack (1) comprising at least n- an anode layer (2) n- a cathode layer (3) n- a light emission layer (4) n- a charge transport layer (5,6) arranged between said light emission layer (4) and at least one of said anode layer (2) and cathode layer (3), nwherein a first domain (21) of said light-emitting diode stack (1) is adapted to provide a first charge injection and/or transport energy barrier, and a second domain (22) of said light-emitting diode stack (1) is adapted to provide a second charge injection and/or transport energy barrier, said first domain (21) being located laterally adjacent to said second domain (22), and said second charge injection and/or transport energy barrier being different from said first charge injection and/or transport energy barrier. The light-emitting device of the invention enables the emission of light of different intensities from the same LED. |
