摘要： A display substrate and a display device. The present display substrate is provided with a first side and a second side, and comprises a first to a third display region. The first display region comprises first pixel repeating units, and allows light from the first side to at least partially penetrate to the second side. The second display region comprises second pixel repeating units and fourth pixel repeating units. The third display region comprises third pixel repeating units. The central connecting line of each first pixel repeating unit to a corresponding fourth pixel repeating unit is approximately parallel to a first direction, and each first pixel repeating unit is electrically connected to the corresponding fourth pixel repeating unit by means of t transparent connecting traces. The pitch of the first and of the second pixel repeating units in a second direction is b1, and the pitch of the third pixel repeating units in the second direction is b2, the pitch of the transparent connecting traces in the second direction is D, and the maximum number s of first pixel repeating units comprised in the first direction satisfying s ≤ 2 ∗ Floor(b1/((D ∗ t))).

摘要： A display substrate and a display device are provided. The display substrate (01) has a first side and a second side, and includes a display region. The first display region (11) includes a first light-emitting element (411), and allows light from the first side to be at least partially transmitted to the second side. The second display region (12) includes a first pixel circuit (412), a second light-emitting element (421), and a second pixel circuit (422). The third display region (13) includes a third light-emitting element (431) and a third pixel circuit (432). The display substrate (01) is provided with a first signal line (21), a second signal line (22), and a third signal line (23). The first winding portion (212) of the first signal line (21) extends along a curve, the first winding portion (212), the first bending portion (213), and the first connecting portion (214) are all located in the second display region (12). The first signal line (21) is configured to transmit a first driving signal to the first pixel circuit (412) so as to drive the first light-emitting element (411) to emit light. The second signal line (22) is configured to transmit a second driving signal to the second pixel circuit (422) and the third pixel circuit (423) so as to drive the second light-emitting element (421) and the third light-emitting element (431) to emit light. The third signal line (23) is floating, and is in the second display region (12) and extends along the first direction. The display substrate (01) can balance circuit environment and optimize wiring design.
