Abstract
Provided is a driving method of a display panel, which relates to a field of a display technology. The display panel includes a pixel array, the pixel array comprises a plurality of rows of sub-pixels, and the driving method includes: driving, in a same display frame, different sub-pixels in a row of the sub-pixels respectively by a forward driving signal and a negative driving signal, wherein a voltage conversion rate of the forward driving signal is greater than a voltage conversion rate of the negative driving signal under a same display gray scale. A driving circuit, a driving chip and a display device are further provided.
