Pixel driving circuit, pixel driving method and display panel

A pixel driving method for driving a pixel driving circuit, comprising:

• in a charging phase, turning on a first transistor with a scan signal of a first scan line, turning on a second transistor with a scan signal of a second scan line, and turning off a charge share switch with a scan signal of a third scan line;
• in a light enable phase, turning off the first transistor with the scan signal of the first scan line, turning off the second transistor with the scan signal of the second scan line, and turning off the charge share switch with the scan signal of the third scan line;
• and
• in a data polarity switching phase, when data polarity is switched to a blanking area turning on the charge share switch with the scan signal of the third scan line, then turning off the first transistor with the scan signal of the first scan line, and turning off the second transistor with the scan signal of the second scan line.

• a pixel unit;
• and
• a pixel driving circuit corresponding to the pixel unit one to one, comprising:

• and
• a charge share switch, a control terminal of the charge share switch being connected to a third scan line, a first terminal of the charge share switch being connected to the first node A, a second terminal of the charge share switch being connected to the second node B, and the control terminal of the charge share switch being capable of responding to a scan signal of the third scan line to enable the first node A to be connected to the second node B;
• when data polarity is switched to a blanking area, the charge share switch receives the third scan signal and is turned on, and the first node A is connected to the second node B, so that the charge stored by the first capacitor and the charge stored by the second capacitor are shared, and then the voltage is neutralized.
