Abstract: This application discloses a pixel driving architecture, a display panel, and a display device. The pixel driving architecture uses three hybrid inversion modes of column inversion, one-plus-two-line point inversion, and two-line point inversion to drive the display panel. This improves the subjective vertical flicker brought about when the Strip architecture is driven by the driving mode of column inversion alone, and compared with the one-plus-two-line point inversion or two-line point inversion driving mode, the charging effect of the panel is better, and can make the twill disappear.
