Backlight, regulation method thereof, regulation device and display device
The present invention discloses a backlight, a regulation method thereof, a regulation device and a display device. The backlight comprises a driving unit, a register, a PWM unit and a light-emitting unit, the PWM unit is connected between the driving unit and the light-emitting unit, and the register is connected to the PWM unit. The driving unit is used for converting a voltage signal to a primary driving signal; the register is used for defining a preset threshold value, which is the maximum value of duty ratio of a signal that the PWM unit outputs when performing a PWM process; the PWM unit is used for regulating duty ratio of the primary driving signal according to the preset threshold value and generating a regulated driving signal; and the light-emitting unit is used for emitting light when being driven by the regulated driving signal.
