Abstract

The invention discloses a driving method of a display panel, the display panel comprises a plurality of pixel unit groups, each pixel unit group comprises M pixel unit rows, M is an integer not less than 2, and the plurality of pixel unit groups are arranged along a direction vertical to a straight line corresponding to the pixel unit rows; the driving method comprises the following steps: comprising four continuous time periods, T1, T2, T3 and T4, in one frame time, wherein a first data voltage signal is loaded to the first pixel unit row to the Mth pixel unit row in the T1 time period; loading a first buffer voltage signal to the Mth pixel unit row in the T2 time period; loading a second buffer voltage signal to the (M + 1) th pixel unit row in the T3 time period; and loading a second data voltage signal to the (M + 1) th pixel unit row to the 2M th pixel unit row in the T4 time period. The invention further discloses a display panel. According to the invention, the problems of insufficient charging of the pixel unit and abnormal picture display caused by reversal of charging polarity of the pixel unit can be solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method for driving a display panel and the display panel. Background technique [0002] As people's demand for large-size, high-resolution display panels continues to increase, large-size display panels are also developing rapidly. Currently, one of the factors restricting large-sized display panels with high performance and high resolution is the refresh rate. The refresh rate is the number of times the screen is refreshed per second. Display panels of different sizes have different refresh rate requirements. For large-size display panels (such as 50 inches or more), a higher refresh rate is required to meet better visual requirements. [0003] The screen refresh method of the liquid crystal display panel is progressive refresh. Taking a full high-definition liquid crystal display panel as an example, the picture is refreshed 60 times per second, and the time ...
