SUMMARY OF THE INVENTION In order to pursue (4) power consumption, the present invention achieves the objective of providing a liquid crystal display device capable of driving a liquid crystal display device with low power consumption by means of a method of the patent document. The liquid crystal display device that drives the switching element, the pixel electrode, and the auxiliary capacitor for the driving and the use of the pixel electrode as one of the 1374433 correction date: 101.7.17 correction. In the other auxiliary force of the auxiliary capacitor, (4) pure (four) turn, the voltage of the halogen electrode changes from low level to high; = = the signal voltage turns on the bit. The difference is that the pole of the pole is changed from the high level to the low level. In order to change the polarity of the U pole signal, the element is applied to the auxiliary capacitor before the element is changed from the high level to the second level. Repeatedly:: When the component is closed, it does not need to be closed during the shutdown period, in order to prevent the value from the lucky value above:;::? The idle voltage of the device is controlled to close the closing gate of the component between the predetermined ones. According to the present invention, since the pixel is turned on and off, the pixel power is low, so that the present invention can be powered by Wa. And using the halogen electrode to prepare the switch element, the halogen element, the sign is:: auxiliary capacitor:; 21: the auxiliary capacitor of the electrode, the characteristic signal of the electrode is switched to :::::ξ2 from the negative voltage The voltage of the pixel electrode is switched to the negative electrode by the low phase of the micro phase, and the voltage of the pixel is switched to the negative electrode: Correction date of No. 97103919: The correction of 101.7.17 can reduce the voltage of the halogen during the closing of the switch in the same manner as the driving method of the liquid crystal display device of the present invention. The amplitude of the gate voltage is sought to drive the lightning circuit = the voltage of the fTFT element is reduced, so that the cost can be reduced and the power consumption can be reduced. According to the present invention, the voltage of the H is switched to the negative electrode during the gold shutdown period. After the sex I:, because the halogen battery will not be reduced, because of the small amplitude of the electric power, and seek to reduce the power of electricity.

The gray % pulse t2 changes the auxiliary capacitor voltage from the low level to the high level at the clock t3 ' after the gate voltage is lowered and τρτ μ is turned off.

Therefore, The charge redistribution occurs between the liquid crystal capacitor and the auxiliary electric valley 20, and the drawing is performed.

Make the leaf 1 switch. In order to prevent the leakage from the liquid, therefore, the value of the threshold voltage and the threshold voltage of the drain voltage must be controlled at a lower level than the source and the value of V. Voltage: 1374433 Revision No. 97103919: 101.7.17 Correction of the book A liquid crystal display device is used to switch the voltage of the halogen (bunt voltage) from the positive signal voltage to the negative signal voltage: 14 applies the gate voltage t4 before the gate voltage to switch the auxiliary capacitor voltage from the 咼 level Low level. Although, during the off period after turning on and off the gate of the FT Μ ,, the auxiliary capacitor voltage is switched from the high level to the low level, so that the amount can be reduced. In the form of P2), in the form of the yoke, since the auxiliary capacitor voltage is switched from the high level to the low level when the TFT 14 is turned on, the negative polarity period can be made. The bucker voltage is kept at a high value. Therefore, since the gate voltage can be turned off when the switch is turned off, the amplitude of the power supply 1 voltage is low when the switch is known as w. Therefore, the power supply can be reduced. 'Asia can reduce power consumption. [Industry use possibility], it can reduce the effect of gate voltage electrification. It is quite useful in terms of active torque.
