Abstract

The application discloses a driving method and device for a display panel. The method includes the following step: when four scan driving signals input by a scan driving line are received, the even-column pixel units in a first row of pixel units are driven by a first scan driving signal, and the even-column pixel units in a second row of pixel units are driven by a second scan driving signal, wherein the on duration for the first scan driving signal to drive the first row of pixel units to realize conduction is longer than the on duration for the second scan driving signal to drive the secondrow of pixel units to realize conduction. Obviously, the pixel units are driven by two different scan driving signals in the row direction, the difference between the charging durations for data driving signals to charge the pixel units is indirectly controlled, high-voltage pixel units and low-voltage pixel units are arranged alternately, and color shift is improved without affecting the permeability of the panel.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, in particular to a method and device for driving a display panel. Background technique [0002] Most of the current large-size liquid crystal display panels are negative Vertical Alignment (VA) liquid crystals or In-Plane Switching (IPS) liquid crystals. [0003] Comparing VA liquid crystal technology with IPS liquid crystal technology, it can be found that VA liquid crystal technology has higher production efficiency and lower manufacturing cost, but its optical properties are worse than IPS liquid crystal technology, and there are more obvious defects in optical properties. . [0004] Especially when applicable to large size display panels, see figure 1 , during the driving process of VA liquid crystal, if the display panel is viewed from a small viewing angle, for example, the brightness of the pixel will change linearly with the voltage, see figure 1 The ideal curv...
