Abstract

The invention discloses a driving circuit, a driving method and a display panel, and the driving circuit comprises a time schedule controller which comprises a first pin; the power management chip comprises a second pin; the power supply management chip is electrically connected with the first shared discharge rod; the power supply management chip is electrically connected with the second shared discharge rod; wherein the first pin is electrically connected with the second pin, the power management chip outputs voltages with opposite polarities to the first shared discharge rod and the second shared discharge rod at the same time, and the time schedule controller controls a level signal of the first pin to be switched between a high level and a low level in a blanking time interval of each frame. And the power management chip is used for reversing the polarity of the voltage of the first shared discharge rod and the polarity of the voltage of the second shared discharge rod under the control of a level signal of the first pin. According to the invention, the problem that the transmitted level signal is interfered to cause the abnormal image of the display panel can be avoided.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a driving circuit, a driving method and a display panel. Background technique [0002] With the continuous improvement of information technology and living standards, people have higher and higher requirements for display quality such as transmittance and viewing angle. To improve the viewing angle, it is necessary to divide the pixels into multiple domains, but this will bring about a loss of transmittance, so the viewing angle and transmittance are inversely beneficial. The shared discharge rod technology is a technology that can improve the low gray-scale viewing angle. The shared discharge rod technology is to have two shared discharge rods on the display panel. The two shared discharge rods are a positive polarity shared discharge rod and a negative polarity. The voltages of the shared discharge rods, the positive polarity shared discharge rods and the negat...
