Pixel driving method, pixel driving circuit and display device

A pixel driving circuit comprising:

• a data interface configured to receive image data including pixel data for at least one pixel;
• a data processing circuit configured to determine a data voltage signal for a target pixel based on pixel data for the target pixel in the image data;
• a pixel electrode driving circuit comprising a first charging circuit and a second charging circuit,
• wherein the first charging circuit is configured to, in response to a first enable signal being valid, drive the target pixel in a first display mode, in which operations are performed which comprise updating the data voltage signal at a first frequency, and providing the data voltage signal for the target pixel so that a driving voltage of the target pixel is determined as a voltage difference between the data voltage signal and a common voltage signal, wherein the common voltage signal is a reference voltage signal common to all pixels, and
• wherein the second charging circuit is configured to, in response to a second enable signal being valid, drive the target pixel in a second display mode, in which operations are performed which comprise updating the data voltage signal at a second frequency, adjusting the data voltage signal according to pixel data for the target pixel, and providing the adjusted data voltage signal for the target pixel so that a driving voltage of the target pixel is determined as a maximum driving voltage or a minimum driving voltage, wherein the second frequency is lower than the first frequency.
