Abstract
A backlight source for instrument includes a backlight source region and a pointer region. The backlight source region includes at least two sub-regions, each of which is provided with a backlight source independently. The pointer region is provided with an instrument pointer. When the instrument pointer is turned into one of the at least two sub-regions, the backlight source which corresponds to the sub-region emits light individually. Thus, the backlight source is saved and the energy consumption is reduced. Backlight sources corresponding to different sub-regions emit light of different colors, and the backlight sources of different colors are sequentially arranged according to warning degree and thus can have a warning function. Further, an operation method of backlight source for instrument and an instrument are further provided.
