Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present disclosure claims priority to Chinese Patent Application No. 202310814548.9, filed Jul. 5, 2023, the entire disclosure of which is incorporated herein by reference. TECHNICAL FIELD The present disclosure relates to the field of driving display technology, particularly, to a driving method, a driving device, a display device and an electronic device. BACKGROUND With the development of liquid crystal display (LCD) technology, the requirements for thin-film transistor liquid crystal displays in terms of high resolution, wide viewing angle, high response speed, high opening rate and so on are getting higher and higher, and along with the shrinking of the size of the pixel, the line spacing on the Thin Film Transistor (TFT) substrate is getting smaller and smaller, and the coupling between different signal lines is aggravated, so that when a signal jumps, it may affect the stability of other signals in the periphery thereof. Therefore, the color crosstalk has been a common phenomenon in display defects of the LCD, which specifically refers to a screen of a certain region will affect the screen of other regions, resulting in a poor display phenomenon. According to the occurrence of crosstalk in different locations, the crosstalk can be divided into a vertical crosstalk and a horizontal crosstalk. The crosstalk phenomenon is caused by the capacitance coupling effect between the data line and the common electrode. For example, when the potential of the data line changes, the parasitic capacitance between the data line and the common electrode forms an instantaneous potential jump in the common electrode line. At this time, if the signal of the common electrode delays more seriously or the driving ability of the voltage is insufficient, its' potential can not be quickly restored to the preset potential, and the jump of this potential will pull down the trans-voltage in the pixel through the coupling effect of the storage capacitance, resulting in a reduction of the luminance of the pixel, thereby forming the crosstalk. SUMMARY There are provided a driving method, a driving device, a display device, and an electronic device according to the embodiments of the present disclosure. The technical solution is as below: A first aspect of the embodiments of the present disclosure provides a driving method, which includes: detecting a data signal of a to-be-displayed screen to obtain a gray scale value of each region in the to-be-displayed screen;determining whether there is a color crosstalk in the to-be-displayed screen based on the gray scale value of each region;determining a target region and a to-be-calibrated region based on the gray scale value, when there is the color crosstalk in the to-be-displayed screen, wherein a gray scale value of target color pixel in the target region is greater than 0, and gray scale values of color pixels in the target region other than the target color pixel are all equal to 0, and the target color pixel is a red pixel, a blue pixel or a green pixel, the to-be-calibrated region is a region adjacent to the target region on a data line, and a gray scale value of each color pixel in the to-be-calibrated region is the same;obtaining an absolute value of a gray scale difference between the color pixel in the to-be-calibrated region and the target color pixel in the target region on the same data line;determining whether the absolute value of the gray scale difference is greater than a preset threshold;determining target compensation data from a pre-obtained compensation data set based on the absolute value of the gray scale difference, when the absolute value of the gray scale difference is greater than the preset threshold; andsending the target compensation data to a driver for the driver compensating for display data of the to-be-calibrated region based on the target compensation data, to drive the to-be-displayed screen to display.
