Claim:
1. An apparatus for reducing power consumption of a liquid crystal panel, comprising: Thin Film Transistors formed on each of data lines, a cut line formed in the direction parallel to gate lines and connected to the gate of the TFTs, and a switching control unit; wherein, the apparatus further comprises a timer/counter controlling register for informing the switching control unit via a timing control signal that the data lines start to transmit the data signal and during the transmission of the data signal, and informing the switching control unit via the timing control signal that the transmission of the data signal corresponding to the gate lines located above each of the cut line is completed, the switching control unit is used to control the on/off state of the TFTs via the cut line during transmission of a data signal so as to control the number of capacitors to be charged on the data lines of the liquid crystal panel, the switching control unit is adapted to control all the TFTs to be turned on via the cut line when being informed by the timer/counter controlling register that the data lines start to transmit the data signal, so that all the capacitors on the data lines are charged; and during the transmission of the data signal, control the TFTs connected to the cut line located under the gate lines which complete the transmission of the data signal to be turned off, via the cut line located under the gate lines which complete the transmission of the data signal, when being informed by the timer/counter controlling register that the transmission of the data signal corresponding to the gate lines located above each of the cut line is completed, so that the capacitors on the data lines corresponding to gate lines located under each of the cut line are charged to continue the transmission of the data signal.
