Method for driving display device
To suppress degradation of a transistor. A method for driving a liquid crystal display device has a first period and a second period. In the first period, a first transistor and a second transistor are alternately turned on and off repeatedly, and a third transistor and a fourth transistor are turned off. In the second period, the first transistor and the second transistor are turned off, and the third transistor and the fourth transistor are alternately turned on and off repeatedly. Accordingly, the time during which the transistor is on can be reduced, so that degradation of characteristics of the transistor can be suppressed.

The third input sub-circuit is configured to change the potential of the first node in the second phase.
GOA circuit and display panel
The present application provides a GOA circuit and a display panel. In the GOA circuit, one of two GOA units of a same stage in GOA sub circuits at left and right sides of the display panel is deployed only with an all-on module and the other one of the two GOA units is deployed only with an all-off module. In such a way, both the number of the all-on modules and the number of the all-off modules required in the GOA unit are halved, thereby reducing the area occupied by the GOA circuit. It is beneficial for realizing a display panel with a narrow bezel.
TFT ARRAY SUBSTRATE
A thin-film transistor (TFT) array substrate is provided. The TFT array substrate is structured to change the way that sub-pixels are arranged so that during a displaying period of a frame of image, the sub-pixels that have inconsistent brightness/darkness become alternate with each other spatially so that a displaying defect of vertical bright/dark lines can be improved and the overall resistance of the data line can be reduced to thereby reduce resistance-capacitance delay and prevent incorrect charging at a tail end of a scan line or a data line.
