Display substrates, display panels and display devices

A display panel having a display substrate, the display substrate comprising:

• a display area comprising:
• a first display area;
• a second display area, a light transmittance of the first display area being greater than a light transmittance of the second display area;
• a third display area disposed between the first display area and the second display area, the light transmittance of the first display area being greater than a light transmittance of the third display area;
• a plurality of sub-pixels, disposed in the first display area, the second display area, and the third display area;
• a plurality of pixel circuits corresponding to the plurality of sub-pixels one to one, the pixel circuits corresponding to the sub-pixels being disposed in the second display area arranged in the second display area, and the pixel circuits corresponding to the sub-pixels in the third display area being arranged in the third display area;
• and
• a plurality of signal lines comprising a plurality of data lines, the data lines comprising a plurality of first data lines, a plurality of second data lines and a plurality of third data lines;
• wherein the pixel circuits corresponding to the sub-pixels arranged along a first direction in the display area are connected to a same signal line;
• at least one of the plurality of signal lines simultaneously connected with the pixel circuits corresponding to the sub-pixels in the first display area, the pixel circuits corresponding to the sub-pixels in the second display area, and the pixel circuits corresponding to the sub-pixels in the third display area;
• the first data lines are connected to the pixel circuits corresponding to the sub-pixels in the first display area, the pixel circuits corresponding to the sub-pixels in the second display area and the pixel circuits corresponding to the sub-pixels in the third display area;
• the second data lines are connected to the pixel circuits corresponding to the sub-pixels in the second display area and the pixel circuits corresponding to the sub-pixels in the third display area.
