Abstract

The present disclosure relates to the technical field of light adjustment. Disclosed are a dimming module, a circuit board, a backlight control panel and an electronic device. The dimming module comprises a mainboard testing circuit, a controller, a voltage boost circuit and a backlight control circuit. According to a backlight PWM adjustment signal input by a mainboard, the mainboard testing circuit controls the voltage of a first node. In response to the backlight PWM adjustment signal, the controller generates a backlight PWM drive signal. According to the backlight PWM driving signal, the voltage boost circuit provides a light-emitting voltage for a light-emitting member. According to the voltage of the first node, the backlight control circuit controls a loop so as to control the light-emitting member. The backlight PWM adjustment signal directly drives the backlight control circuit, so as to control the working state of the light-emitting member; thus, without needing to be converted and processed by the controller, the signal can drive the backlight control circuit to work. Since the backlight PWM adjustment signal input by the mainboard is relatively stable and reliable, the signal is capable of reliably and stably driving the backlight control circuit, thus helping to improve the working reliability of the dimming module.
