Claim Text:
1. A voltage-applying circuit for LC photo-alignment, comprising: a plurality of liquid crystal panels each of which comprises G_Odd, G_Even, R, G, B, CF_Com, and TFT_Com signal input terminals; a plurality of voltage-applying point groups connected to the liquid crystal panels, each voltage-applying point group comprising G_Odd, G_Even, R, G, B, CF_Com, and TFT_Com voltage-applying points respectively connected to the G_Odd, G_Even, R, G, B, CF_Com, and TFT_Com signal input terminals of the corresponding liquid crystal panel; a voltage supplying module comprising a plurality of power sources each of which is connected to the voltage-applying points of the voltage-applying point groups having the same function; and a plurality of switch control circuits each of which is connected between each liquid crystal panel and the voltage-applying point group and is configured for disconnecting the G_Odd, G_Even, R, G, and B signal input terminals of the liquid crystal panel from the G_Odd, G_Even, R, G, and B voltage-applying points of the voltage-applying point group respectively when a current of the CF_Com signal input terminal of one of the liquid crystal panels becomes abnormal.
