The plurality of illumination tiles are arranged in a two-dimensional array. The illumination tiles are constructed and arranged so as to provide a substantially contiguous illumination surface comprising the light emission surfaces of the plurality of the illumination tiles. Each illumination tile is illuminated by at least one solid state light-emitting device. A method of local dimming an illumination assembly of a display (e.g., LCD) backlight unit is also provided.
