A TFT LCD driving circuit, a timing controller and a method for reducing the power consumption thereof are disclosed, wherein the timing controller includes a video data determining circuit, and a power-saving source/gate timing control circuit. The video data determining circuit receives a video data and obtains an effective resolution parameter value from the video data. If the video data is not a full-frame video data and the effective resolution parameter vale of the video data is smaller than the resolution of the LCD panel, the video data determining circuit triggers the power-saving source/gate timing control circuit to control the operation of a plurality of gate driver ICs and a plurality of source driver ICs of the TFT LCD driving circuit, in order to reduce the number of the "turning-on" times of these gate driver ICs and source driver ICs.
