    Abstract: A display substrate and a display device are disclosed. The display substrate (10) includes a plurality of repeating units (100), a plurality of primary signal lines (21) and an auxiliary signal line (22). Each of the repeating units (100) includes a first sub-pixel (R1), a second sub-pixel (B1) and two third sub-pixels (G1, G2). The two third sub-pixels (G1, G2) are located between two adjacent primary signal lines (21). In each of the repeating units (100), the first sub-pixel (R1) and the second sub-pixel (B1) are arranged in a first direction (X), and the two third sub-pixels (G1, G2) are arranged in a second direction (Y). The first direction (X) and the second direction (Y) are different directions. At least one auxiliary signal line (22) is disposed between the two adjacent primary signal lines (21). Two ends of the auxiliary signal line (22) are respectively connected to the two adjacent primary signal lines (21). The two third sub-pixels (G1, G2) are respectively located on two sides of the auxiliary signal line (22).

    Abstract: A display screen, a display device, a display circuit used for the display screen and a brightness compensation method therefor. The display screen (10) includes a normal display area (11) and a transparent display area (12). The display circuit (20) includes: a first pixel circuit (21), wherein the first pixel circuit is arranged at the normal display area; and a second pixel circuit (22), wherein the second pixel circuit is arranged at the transparent display area. The structure of the first pixel circuit is different from that of the second pixel circuit, so that the light transmittance of the transparent display area is higher than the light transmittance of the normal display area.
