Abstract
A light-emitting unit in a display panel includes a light-emitting element, a data writing unit configured to write a data signal in a first stage, a driving unit connected to the light-emitting element and the data writing unit, and a turn-on control unit connected between the light-emitting element and a first voltage line. The driving unit is configured to generate a driving current based on the data signal in the first stage to drive the light-emitting element to emit light, and no driving current generated by the driving unit drives the light-emitting element to emit light in a second stage. The first voltage line is configured to transmit a first sub-voltage signal and a second sub-voltage signal in the first stage and the second stage respectively, thereby causing the electrical disconnection and electrical connection between the first voltage line and the light-emitting element respectively.
