Claim 7:
8. A lighting method of a backlight module, wherein the backlight module comprises at least one drive light-emitting group, the drive light-emitting group comprising a drive unit, a plurality of light-emitting units and a plurality of line groups, wherein the drive unit is provided with a plurality of signal transmission channels, each signal transmission channel is connected to one light-emitting unit through a corresponding line group, and the signal transmission channel, the line group and the light-emitting unit are arranged in one-to-one correspondence, wherein the line group comprising a main transmission line and a compensation line arranged in parallel, and compensation lines of the plurality of line groups are connected through a control switch group;
the lighting method of the backlight module comprises:
detecting an abnormal signal transmission channel of the signal transmission channel in the drive unit; and
controlling the control switch group to allow a compensation line corresponding to the abnormal signal transmission channel to be conducted with a compensation line corresponding to at least one normal signal transmission channel in the plurality of signal transmission channels;

wherein after detecting the abnormal signal transmission channel of the signal transmission channel in the drive unit, the method further comprises:
detecting whether there is an idle signal transmission channel in the drive unit and determining an idle channel;

wherein controlling the control switch group to allow the compensation line corresponding to the abnormal signal transmission channel to be conducted with the compensation line corresponding to at least one normal signal transmission channel in the plurality of signal transmission channels comprises:
controlling the control switch group to allow the compensation line corresponding to the abnormal signal transmission channel to be conducted with a compensation line corresponding to the idle channel in the plurality of signal transmission channels.
