1. A light-emission control signal generation circuitry, comprising: a first control node control circuitry, a second control node control circuitry, a first node control circuitry, a second node control circuitry and an output circuitry, wherein
the first control node control circuitry is configured to control a potential at a first control node to be a first voltage;
the second control node control circuitry is configured to control a second control node to be electrically coupled to or electrically decoupled from the first control node;
the first node control circuitry is configured to control a potential at a first node under the control of the potential at the first control node;
the second node control circuitry is configured to control a potential at a second node under the control of the potential at the first control node and the potential at the first node; and
the output circuitry is configured to generate a light-emission control signal under the control of the potential at the first node and the potential at the second node.
