Problems solved by technology
[0003] At present, in order to save costs of liquid crystal displays, many panel manufacturers will adopt a dual gate structure, and the data line will be halved, that is, the number of soft mold bonding particles of the source die can be halved, and the scan line (scan line) ) is doubled, that is, the number of soft-mode bonding of the gate die is doubled, but the soft-mode bonding of the gate die is much cheaper than the soft-mode bonding of the source die, so in general, the dual gate (dual Gate) architecture will cut costs
However, for the sake of image quality, the dual gate architecture is usually driven with 1+2line or 2line inversion mode, which will cause the problem of bright and dark lines at low gray levels
[0004] When the dual Gate architecture is used with the 2line inversion method, there will be problems with bright and dark lines

The present application provides a display panel and a driving method thereof. The display panel includes: a substrate; a plurality of data lines arranged on the substrate; a plurality of scanning lines arranged on the substrate and connected to the substrate. The data lines are arranged across and define a plurality of pixel areas; a plurality of pixel units are arranged on the pixel areas and are respectively electrically coupled with the data lines and the scanning lines; each pixel area includes at least one Pixel circuit; during the first scanning period, apply a first turn-on voltage to the pixel units on the 2n-1 row scanning lines; and during the second scanning period, apply a second turn-on voltage to the pixel units on the 2n row scanning lines Voltage; wherein, the adjacent 2n-1th scan line and the 2nth scan line are coupled to the same data line, and n is a positive number; wherein, the magnitude of the first turn-on voltage and the second turn-on voltage are the same, and the charging time of the first turn-on voltage is equal to the charging time of the second turn-on voltage.
Description
technical field [0001] The present application relates to the display field, relates to pixel circuits and related driving methods, and in particular relates to a display panel and a driving method thereof. Background technique [0002] A liquid crystal display panel usually consists of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer, LCD) arranged between the two substrates. ), its working principle is to control the rotation of the liquid crystal molecules in the liquid crystal layer by applying a driving voltage on two glass substrates, and refract the light from the backlight module to produce a picture. [0003] At present, in order to save costs of liquid crystal displays, many panel manufacturers will adopt a dual gate structure, and the data line will be halved, that is, the number of soft mold bonding particles of the sour...
