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.
