Abstract

The present description concerns an elementary module (100) of a display device enabling to display at least one pixel of an image, the module comprising: a first assembly of N LEDs (101(i,j)) distributed into M groups (G(i)), at least one of the M groups comprising at least two LEDs, where N and M are integers, with M greater than or equal to 2; and a control circuit comprising M bias circuits (103(i)) respectively associated with the M groups of LEDs, each bias circuit (103(i)) being shared by the LEDs of the corresponding group (G(i)) and being adapted to successively controlling the emission of the LEDs of the group.
