| description | The invention relates to a device for illuminating a liquid crystal screen. The device comprises a light box (1) located behind the screen (2). The light box (1) comprises a plurality of light sources (4). The device further comprises first means (3) to power the light sources (4). The first means (4) comprise second means enabling, under steady conditions, at least one of the light sources to be extinguished while the other sources remain lit. |
