摘要： A backlight module includes a backlight source and a backlight driving unit. The backlight source includes a white-light source and a compensating light source. The backlight driving unit includes a primary driving module and a compensating driving module. The primary driving module, within a compensation time duration, according to a current environmental temperature, selects a compensation-driving function corresponding to the current environmental temperature; and according to the selected compensation-driving function, supplies a compensation controlling signal to the compensating driving module. The compensating driving module acquires the compensation controlling signal, and according to the compensation controlling signal, supplies a driving signal to the compensating light source. The compensating light source acquires the driving signal, and emits light when driven by the driving signal, whereby a variation value of a white-dot chromaticity coordinate of the displaying module within the compensation time duration is within a preset range.
