Abstract
A display substrate includes a driving circuitry, and the driving circuitry includes a first node control circuitry, a second node control circuitry and an output circuitry. The output circuitry is configured to control a driving signal output end to be electrically coupled to a second voltage line under the control of a potential at a first node, and control the driving signal output end to be electrically coupled to a first voltage line under the control of a potential at a second node. Transistors of the output circuitry are arranged at a side of the second voltage line away from a display region, and transistors of the first node control circuitry and transistors of the second node control circuitry are arranged at a side of the transistors of the output circuitry away from the second voltage line.
