Display substrate and driving method thereof, and display device

A full-screen display device, comprising:

• a display substrate having a light emitting side, the display substrate comprising:
• a first display sub-region, comprising a first pixel unit and a second pixel unit, the first pixel unit comprising a first sub-pixel and a second sub-pixel, the second pixel unit comprising a second sub-pixel and a third sub-pixel;
• and
• a second display sub-region, comprising a third pixel unit and a first transparent region, the third pixel unit comprising a first sub-pixel, a second sub-pixel and a third sub-pixel;
• and
• a camera, located at a side of the display substrate opposite to the light emitting side of the display substrate and disposed corresponding to the second display sub-region,
• wherein the first transparent region is configured such that a light transmittance of the second display sub-region is greater than a light transmittance of the first display sub-region,
• wherein an area of the first transparent region is greater than or equal to a sum of areas of the first sub-pixel, the second sub-pixel and the third sub-pixel in the third pixel unit,
• wherein each of the first sub-pixel, the second sub-pixel, and the third sub-pixel comprises a laminated structure composed of an anode layer, a light emitting layer, and a cathode layer,
• wherein in the third pixel unit of the second display sub-region, the first sub-pixel and the third sub-pixel are arranged in a same row, and the second sub-pixel is located in a row adjacent to the row where the first sub-pixel and the third sub-pixel are located, so that the second sub-pixel and the first sub-pixel are arranged in staggered rows, and
• wherein the second display sub-region comprises a plurality of first pixel units, second pixel units, and third pixel units, sub-pixels of a same color in a row direction are arranged at substantially equal intervals, and sub-pixels of a same color in a column direction are arranged at substantially equal intervals.
