U-led, u-led device, display and method for the same

A control circuit for adjusting a brightness of at least one μ-LED, comprising a current driving element having:

• a control terminal;
• a first terminal which is connected to a first potential;
• a capacitor connected between the control terminal and the first potential and forming a capacitive voltage divider with a defined capacitance between the control terminal and the first terminal;
• a control element adapted to apply a control signal to the control terminal during a first time period, wherein the control signal is an analog signal on a basis of which a current flowing through the at least one μ-LED is adjustable during the first time period;
• wherein during a second time period subsequent to the first time period, the current flowing through the at least one μ-LED is determined by a reduced control signal formed by the control signal during the first time period and the capacitive voltage divider;
• wherein the control element is arranged to provide the control signal during the first time period within either a first voltage interval or a second voltage interval higher than the first voltage interval to control a perceptible average brightness level of the at least one μ-LED averaged over a time period comprising the first time period and the second time period;
• wherein providing the control signal during the first time period within the first voltage interval causes the perceptible average brightness level of the at least one μ-LED to depend more on the current flowing through the at least one μ-LED during the first time period than during the second time period;
• and
• wherein providing the control signal during the first time period within the second voltage interval causes the perceptible average brightness level of the at least one μ-LED to depend more on the current flowing through the at least one μ-LED during the second time period than during the first time period.
