Abstract: The present application provides a display panel control method and a display module. A display voltage corresponding to corresponding pixel unit can be compensated for based on a difference between a first feed-through voltage generated by a pixel electrode when a first transistor is turned from on to off and a second feed-through voltage generated by a common electrode when a second transistor is turned from on to off, so as to improve the problem such as the flicker or the image sticking in the display picture due to the unevenness of the feed-through voltages.

Abstract: A dark area repair method and a dark area repair device of a curved liquid crystal display panel are provided. It is concluded through a summary that, under different curvatures, there is a quantitative relationship between a dark area and a first pretilt angle and a second pretilt angle. It determines whether a difference value of the first pretilt angle and the second pretilt angle is greater than or equal to a dark area critical value, and if so, there is no dark area. It is convenient to determine whether the dark area will show in the panel in advance in an early experimental stage, which can be used to guide an improvement of the dark area.

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.
