Classification: CPC G  Y | IPC G

Claim 12:
13. The lighting method of the backlight module according to claim 8, further comprising:
comparing a current value that enables the light-emitting unit corresponding to the abnormal signal transmission channel to be lightened with a preset current value when there is no idle channel in the signal transmission channels of all the drive units;
controlling a compensation line corresponding to a signal transmission channel closest to the signal transmission channel to be connected to the compensation line of the abnormal signal transmission channel, when the current value of the light-emitting unit corresponding to the abnormal signal transmission channel is less than or equal to the preset current value, wherein a current of the closest signal transmission channel is shunted to the light-emitting unit corresponding to the abnormal signal transmission channel; and
controlling the compensation line corresponding to the signal transmission channel of the light-emitting unit at a edge position of the backlight module to be connected to the compensation line corresponding to the abnormal signal transmission channel, when the current value of the light-emitting unit corresponding to the abnormal signal transmission channel is larger than the preset current value.
