The present application is applicable to the field of display technology, and provides a method, device and display device for eliminating crosstalk of a display panel. According to the embodiment of the present application, according to the source driving voltage of the mth column of the nth row and the source driving voltage of the mth column of the n-1th row, the influence factor of the common voltage of the mth column of the nth row is obtained; the nth The preset influence factor range to which the influence factor of the public voltage of the mth column of the row belongs; according to the proportion of the number of the nth row influence factors belonging to the kth preset influence factor range in the total number of columns, and the kth preset The kth preset compensation coefficient corresponding to the influence factor range is used to obtain the first compensation signal; according to the first compensation signal, the common voltage of the nth row is compensated; or, according to the first compensation signal, the nth row The source driving voltage of the m column is compensated to eliminate the deviation of the common voltage of the nth row and the mth column, thereby eliminating the deviation of the pixel voltage, thereby eliminating the crosstalk phenomenon, and improving the display effect of the display panel.
Description
technical field [0001] The present application belongs to the field of display technology, and in particular relates to a method, device and display device for eliminating crosstalk of a display panel. Background technique [0002] With the rapid development of display technology, display panels are widely used in various fields such as entertainment, education, and security, and users have gradually increased requirements for display effects of display panels. [0003] Since the source drive voltage in the display panel is switched between the positive source drive voltage and the negative source drive voltage during output, a parasitic capacitance is generated between the source drive voltage and the common voltage in the display panel and causes coupling effects, This causes the common voltage to change, thereby forming a crosstalk phenomenon, and the display effect is poor. Contents of the invention [0004] In view of this, the embodiment of the present application p...
