Problems solved by technology

When the display screen is switched between frames, the voltage signal on the data signal line is converted from one polarity to another polarity. In this process, the data line needs to be charged to the data signal pole of the previous frame display screen. Therefore, the signal variation of the data signal line during inter-frame switching is larger than that of the data signal line during intra-frame display, making it difficult for the data signal line to achieve charge balance when the polarity is reversed.
Due to the mutual capacitance between the data line and the common electrode, the above-mentioned signal changes on the data line cause more obvious disturbance to the common electrode during inter-frame switching, resulting in flickering of the display screen and reducing the display effect of the display panel

Abstract

The invention discloses a display panel, a display device and a driving method applied to the display panel. The display panel comprises a plurality of data signal lines, a display pixel array and a control unit, wherein the display pixel array comprises a plurality of sub-pixels; the data signal lines are each connected to one line of sub-pixels in the display pixel array, and the data signal lines are used for transmitting data signals to the various sub-pixels; the control unit is connected to at least one data signal line in the data signal line group; and the control unit is used for transmitting a first signal to the various data signal lines in a display intermission between adjacent frames, wherein in the adjacent frames, the data signals applied to the same data signal line are opposite in polarity. According to the implementation mode, the data signal lines can achieve charge balance when polarity is reversed in a same frame, so that a display effect of the display panel is enhanced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a display device and a driving method applied to the display panel. Background technique [0002] With the improvement of display technology, in order to meet the market demand, the display panel is gradually developing in the direction of thinner, thinner frame and high resolution. [0003] In the liquid crystal display panel, if the data line only transmits a voltage signal of one polarity, the liquid crystal molecules will deflect in the same direction for a long time, and polarization will easily occur, thus gradually losing the rotation characteristic. In order to prevent the liquid crystal molecules from being polarized under the bias voltage in the same direction for a long time, two signals of different polarities can be provided to the data line, one is a positive signal higher than the common electrode voltage, and the other is a positive pol...
