Abstract
Driver arrangements () drive first organic light emitting diode circuits () coupled to reference terminals () and first output terminals () and drive second organic light emitting diode circuits () coupled to the first output terminals () and to second output terminals (). The driver arrangements () comprise first/second elements () coupled to the first/second output terminals () and the reference terminals () and first/second switches () coupled to power source terminals () and the first/second output terminals () for controlling the stacked organic light emitting diode circuits () individually. The switches () and the first elements () comprise transistors and the second elements () comprise transistors or diodes. The first/second elements () and the first/second switches () are coupled to each other and via first/second inductors () to the first/second output terminals ().
