A liquid display device 1 and a drive method therefor. The liquid crystal display device 1 is provided with a display panel 11 and a drive circuit 12; the drive circuit 12 is electrically connected to the display panel 11, and the display panel 11 comprises a plurality of pixels P, the pixels P are each provided with a pixel electrode P1 and a common electrode P2; the drive circuit 12 is used for outputting a plurality of data voltages and a common electrode voltage Vcom. The method comprises: at the moment the device is switched on and the drive circuit 12 receives a rising edge of a start signal STV of a first frame of an image at a time point t, the drive circuit 12 transmits the plurality of data voltages to the plurality of pixel electrodes P1 at said time point t, and transmits the common electrode voltage Vcom to the common electrodes P2 at said time point t, such that the plurality of pixels P display an image.
Description
technical field [0001] The present application relates to a liquid crystal display device and a driving method thereof, in particular to a liquid crystal display device and a driving method thereof which can eliminate the whitening phenomenon of the screen at the moment of power-on. Background technique [0002] With the advancement of technology, flat panel display devices have been widely used in various fields, especially liquid crystal display devices, which have gradually replaced traditional cathode ray tube display devices due to their superior characteristics such as light and thin body, low power consumption and no radiation. , And applied to many types of electronic products, such as mobile phones, portable multimedia devices, notebook computers, LCD TVs and LCD screens, etc. [0003] In the known technology, in order to make the liquid crystal display device display images, it is necessary to apply a voltage difference between the pixel electrode and the common el...
