Problems solved by technology
[0004] However, the data signal output by the data line needs a certain boost time to reach the required charging voltage.
The boost time limits the charging speed of the data signal to the liquid crystal capacitor
As the refresh rate requirements of liquid crystal displays are getting higher and higher, the charging speed of the data lines to the liquid crystal capacitors in related technologies can no longer meet the refresh rate requirements of the display.

The present invention relates to the technical field of displays, and provides a pixel charging method, a display panel, and a display device. The display panel includes: a pixel array, a plurality ofscan lines, a plurality of data lines, a first coupling capacitor group, and a first coupling line group. The first coupling capacitor group includes a plurality of first coupling capacitors, first ends of the first coupling capacitors are connected to the data lines, second ends of the first coupling capacitors receive a first coupling signal, and the first coupling capacitors are used for coupling the first coupling signal to a data signal; the first coupling line group includes at least one first coupling line which is used for outputting the first coupling signal; the polarity of the first coupling signal coupled to the data signal is identical to the polarity of a changing direction of the data signal. In the display panel, the coupling signal may accelerate the data signal to reachthe charging voltage, the charging time of the data signal to a liquid capacitor can be reduced, and a technical support is provided for improving the refresh rate of the display device.
Description
technical field [0001] The present disclosure relates to the technical field of displays, and in particular to a pixel charging method, a display panel and a display device. Background technique [0002] Liquid crystal display panels are widely used in various electronic display devices due to their characteristics of power saving, low radiation, and soft light. The liquid crystal display panel mainly includes a plurality of pixels distributed in an array. Each pixel includes a liquid crystal capacitor, and liquid crystal molecules are arranged between the liquid crystal capacitors. By changing the voltage between the two electrodes of the liquid crystal capacitor, the arrangement state of the liquid crystal molecules can be changed, thereby changing the pixel. display brightness. [0003] In the related art, a data signal is sent to each pixel of the pixel array row by row through a data line to charge the liquid crystal capacitor of each pixel, thereby controlling the dis...
