Abstract
The present application discloses a driving circuit, a display panel and an electronic device. The driving circuit includes a voltage output module, a light-emitting device connected between the voltage output module and a second voltage terminal, and a brightness adjusting module connected between the light-emitting device and the voltage output module. In a light-emitting phase, the brightness adjusting module controls a frequency a first voltage signal outputted by the voltage output module applies to the light-emitting device such that the light-emitting device is changed between a light-emitting state and a non-light-emitting state.
