The invention makes use of the effect that the high parasitic capacitance of the OLED leads to a prolonged drop in luminous intensity after each PWM current pulse during PWM operation. This can advantageously be exploited by the first method, which prevents the luminous intensity from falling to zero during the PWM vacancy in order to avoid the so-called beading effect when the OLED is in motion. By the second method, OLED afterglow is suppressed to achieve better color characteristics without considering the beading effect. For this purpose, the falling edge can be shortened or adjusted in a controlled manner. In a third method, this effect is taken into account when the OLED is switched on in such a way that the rising edge is initially shortened by an excessively high drive current in order to achieve a rapid attainment of the setpoint value of the luminous intensity. These methods are implemented by a drive circuit or control unit according to the invention.

The invention relates to the use of the effect that the high parasitic capacities of an organic light emitting diode (OLED) in pulse width modulation (PWM) mode can result in an extended drop in luminosity after every PWM current pulse. This can be advantageously used by means of a first method, which prevents the luminosity from dropping to 0 in the PWM gaps in order to prevent a so-called string of pearls effect when moving the OLED. In a second method, the afterglow of the OLED is counteracted without consideration of the string of pearls effect in order to achieve better color characteristics. Instead, the dropping flanks can be shortened or adjusted under control. In a third method, said effect is addressed upon activating the OLED in that the rising flanks are shortened at the start by an increase of operating current in order to achieve the target luminosity value more quickly. The methods are carried out by an operating circuit or control unit according to the invention.
