This invention relates to a rim system for a display such as a TV or a computer display. Controllable light sources are used for emitting light beam of at least one wavelength into a light guide comprising an inner and an outer side and a front and a back side, the light guide being adapted for guiding incoming light emitted by the light sources. The light guide 5 comprises an out-coupling structure for interacting with the light guided within the light guide such that the light becomes extracted out of the front side of the light guide. The light sources are coupled to the light guide such that the emitted light beam reaching the inner and the outer sides from with hin the light guide becomes reflected under an oblique angle with the respect to the inner and the outer sides.
