Abstract: According to an aspect described herein, a device is proposed for electronically driving an LED comprising a data signal line, a threshold signal line, and a select signal line. Further provided is an LED electrically connected in series with a dual-gate transistor and together therewith between first and second potential terminals. A first control gate of the dual gate transistor is connected to the threshold line. The device also includes a select latch circuit comprising a charge latch connected to a second control gate of the dual gate transistor and to a current line contact of the dual gate transistor, and a control transistor comprising a control terminal connected to the select signal line.

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.
