    Abstract: A picture element for a display device includes a first and a second supply connection, a light-emitting semiconductor device arranged between the first and the second supply terminal, and a comparison unit having a first and a second input and an output. The comparison unit is configured to adjust a voltage at the output in dependence on a comparison of a voltage applied to the first input and a voltage applied to the second input. The picture element also includes a supply switch-configured to control a current flow between the first and the second supply terminal via the light-emitting semiconductor device depending on the voltage applied at the output of the comparison unit. The picture element further includes a selection input, a data input, a memory element and a control switch.
