Embodiment Construction

[0052] It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0053] refer to image 3 , image 3 It is a schematic structural diagram of the display device of the hardware operating environment involved in the solution of the embodiment of the present application.

[0054] Such as image 3 As shown, the display device may include: a processor 1001 , such as a CPU, a communication bus 1002 , a user interface 1003 , a display panel 1004 , and a memory 1005 . Wherein, the communication bus 1002 is used to realize connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. The memory 1005 can be a high-speed RAM memory, or a stable memory (non-volati...

Abstract

Disclosed are a driving method and a device of a display panel. The method includes: driving pixel units in the even-numbered column of a first row of pixel units by a first scanning driving signal, and driving pixel units in the even-numbered column of a second row of by a second scanning driving signal, in which the turned-on time duration for the pixel units of the first row is longer than the turned-on time duration for the pixel units of the second row. As such, the charging time duration is different for different pixel units, and high voltage pixel units and low voltage pixel units are alternately arranged, thereby improving color shift.

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...
