Abstract:
A control signal is provided for turning on and turning off a lamp of a backlight source. For a first duration when the liquid crystal is rotating, adjust a frequency of the control signal to turn on and turn off the lamp of the backlight source consecutively or adjust a duty cycle of the control signal to turn off and then turn on the lamp of the backlight source. Thus, the backlight source has a luminance value for the first duration, and the control signal turns on the lamp of the backlight source for a second duration when the liquid crystal is in the steady state.
