摘要： The invention relates to a scanning backlight system (B2) comprising several light sources (TLl, TL2, TL3, Ll), wherein some of the light sources are driven in a scanning mode of operation and some of the light sources are driven in a continuous mode of operation. The scanning backlight system comprises light sources which together emit a first primary color, for example the primary color green, a second primary color, for example the primary color red, and a third primary color, for example the primary color blue. In a preferred embodiment of the scanning backlight system, the first primary color (being the primary color green) is driven in a scanning mode of operation and the second primary color (being the primary color red) is driven in a continuous mode of operation. In a scanning backlight system in which the primary color green is emitted in a scanning mode of operation, motion artifacts caused by blurring will be significantly reduced, because the sensitivity of the human eye to the primary color green is relatively high. By contrast, the impact of a display system on the reproduction of motion when the primary color red is emitted in a continuous mode of operation is expected to be minor, because the sensitivity of the human eye to the primary color red is relatively low. The cost of the scanning backlight system will be reduced if only some of the light sources are driven in a scanning mode of operation.
