Abstract
A method for controlling a light source driving circuit is provided. The method includes driving a plurality of serially-connected light sources, and measuring a working parameter of the light sources; shorting the light sources sequentially to find out at least a failed light source, when the working parameter is not measured; and remaining shorting the failed light source, and regulating a brightness of the light sources without having the failed light source according to a newest working parameter.
