The backlight power supply chip includes a set pin configured to set a reference current, an input pin, and an output pin. One end of the adjustable resistor circuit is connected to the set pin. The adjustable resistor circuit further includes a control end, where the control end is configured to receive a switching signal. Based on the switching signal, the adjustable resistor circuit selects a resistor branch from a first resistor branch and a second resistor branch to connect to the set pin for generating the reference current. The backlight power supply chip is configured to generate a drive current based on the reference current and a duty cycle of a pulse-width modulation (PWM) signal received by the input pin, and output the drive current by using the output pin."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backlight circuit, electronic device, and backlight adjustment method","description":"A backlight circuit includes a backlight power supply chip and an adjustable resistor circuit.
