FIELD: physics.
SUBSTANCE: circuit (1) with light-emitting diodes is provided with first subcircuits, having first light-emitting diodes (11) and second subcircuits having second light-emitting diodes (13) and switches (14), in conducting states, for switching on the second light-emitting diodes (13) and switching off the first light-emitting diodes (11), and, in non-conducting states, for switching off the second light-emitting diodes (13) and switching on the first light-emitting diodes (11). Also, the first and second subcircuits have different signal characteristics, such as different minimum threshold voltage values, so as to be realised by different types of light-emitting diodes (11, 13) or using a different total number of serial light-emitting diodes (11, 13) or by adding elements with threshold voltage to the first subcircuits. The light-emitting diodes (11, 13) have different colours and can be used backlight.
EFFECT: simplification.
