Luminous film, display element and method for operating a luminous film

A method of operating a luminous film, the luminous film comprising a carrier on or in which several unit cells of light-emitting diodes are arranged, wherein:

• each unit cell comprises a first, a second and a third light-emitting diode,
• the first and second light-emitting diodes of a unit cell are connected anti-parallel to each other, and
• the third light-emitting diode is connected in series with the parallel connection of the first and second light-emitting diodes of the unit cell;
• and wherein each unit cell comprises:
• a first control line, which is electrically conductively connected to a common electrode of the anti-parallel connected first and second light-emitting diode,
• a second control line, which is electrically conductively connected to a common electrode of the first, second and third light-emitting diode, and
• a third control line, which is electrically conductively connected to an electrode of the third light-emitting diode;
• and the method comprises applying signals to the light-emitting diodes of the unit cell such that:
• in at least a first state, signals are applied to the light-emitting diodes in such a way that only one of the light-emitting diodes is active, i.e. light emitting, while the other light-emitting diodes of the unit cell are not active, i.e. are not light emitting, and
• in at least in at least a second state, signals are applied to the light-emitting diodes in such a way that two light-emitting diodes emit light at the same time;
• wherein
• the unit cells are arranged in a row on or in the carrier and are electrically interconnected by their second control lines,
• or wherein
• the unit cells are arranged in segments in a planar manner on or in the carrier and electrically interconnected, wherein unit cells of a segment are connected in series connection with a common first control line, a common second control line, and a common third control line,
• the segments are each controlled individually by respective common second control lines, and
• neighboring segments share one of the common first and common third control lines, such that the total number of control lines is 2*n+1, wherein n is the number of segments.
