Abstract
A pixel circuit includes a potential compensation subcircuit configured to control a junction voltage of a light emitting element to be within a preset voltage range according to an initial voltage input by an initialization reset voltage terminal and a reset sequence input by a reset sequence signal terminal. The preset voltage range is higher than zero and lower than an emission threshold voltage of the light emitting element.
