Abstract: A driving circuit includes a first power signal terminal, a second power signal terminal, a first driving transistor, a light-emitting element, a first storage module, a first boost module, a first light-emitting control module, and a data write module. The driving circuit includes a data write stage, a boost stage, and a light-emitting stage in a same frame. At the data write stage, the data write module transmits a first data signal to the first boost node. At the boost stage, the boost signal terminal transmits a boost signal to the first boost module to increase a potential of the first boost node. At the light-emitting stage, the first light-emitting control module is in conduction, and a signal of the first boost node is transmitted to the first node.
