Abstract
A pixel circuit, a driving method thereof and a light emitting device, and relates to the technical field of display. The pixel circuit comprises driving sub-circuit comprising a control terminal, first terminal and a second terminal, driving sub-circuit being configured to control driving signal flowing through the first terminal and second terminal according to signal of control terminal; first capacitor comprising first pole and second pole coupled to control terminal of driving sub-circuit; first data writing sub-circuit configured to write first initialization signal to first pole of first capacitor in response to first scanning signal, write first data signal into driving sub-circuit in response to first scanning signal, so that signal of control signal of driving sub-circuit changes with first data signal; second data writing sub-circuit configured to write second data signal to first pole of first capacitor in response to second scanning signal.
