Example Embodiment
[0045] Embodiment 1 of the gate drive circuit of the present invention:
[0046] The gate driving circuit provided in this embodiment includes a loading circuit for loading a first gate driving voltage on the gate of a pixel whose data driving voltage is a positive polarity signal, and when the data driving voltage is a negative polarity signal A second gate driving voltage is applied to the gate of the pixel, wherein the first gate driving voltage is higher than the second gate driving voltage.
[0047] The gate driving circuit provided in this embodiment can be applied to the above four driving methods. By applying a second gate driving voltage with a lower voltage to the gate of a pixel whose data driving voltage is a negative signal, the TFT is effectively relieved. The gate bias voltage problem prolongs the service life of the TFT; compared with the prior art, the power consumed by the second gate driving voltage is smaller, which saves the power consumption of the liquid crys...
