More Information
Summary:The invention provides a driving circuit and a fault detection method thereof, a backlight module and a display device. The driving circuit comprises a plurality of light bars, a driving chip, a detection module and a control chip; the detection module is used for detecting a plurality of voltage signals of the light bars and screening out a first voltage signal and a second voltage signal; and the control chip is used for determining whether there is a fault in the plurality of light bars according to the difference between the first voltage signal and the second voltage signal. Through the arrangement of the detection module which can detect the voltage signals of the plurality of light bars and can screen out the first voltage signal and the second voltage signal from the plurality of voltage signals, the control chip can realize fault detection of the light bars according to the difference value of the first voltage signal and the second voltage signal, and the driving circuit can perform processing opera
