Display apparatus and backlight driving module
A display apparatus includes a receiving module, a processing module, a selecting module, a power circuit, and a backlight module. The receiving module receives a pulse width modulating (PWM) signal from an external component. The processing module processes the PWM signal in a predetermined time duration. The selecting module outputs the unadjusted PWM signal to the power circuit in the predetermined time duration, and outputs an adjusted signal after the predetermined duration. The power circuit generates a first driving current for driving the backlight module to emit lights in response to the unadjusted PWM signal while the processing module processes the PWM signal. The backlight module remains a predetermined brightness after the predetermined time.
