Abstract
A pixel circuit includes a main-circuit that controls an organic light-emitting element by controlling a driving current to flow into the organic light-emitting element and a sub-circuit including a first compensation transistor including a gate terminal which receives a first gate signal, a second compensation transistor including a gate terminal which receives a second gate signal, and an initialization transistor including a gate terminal which receives an initialization signal. Here, in a low-frequency driving mode, a driving frequency of the first gate signal is N hertz (Hz), a driving frequency of the initialization signal is N Hz, a driving frequency of the second gate signal is M Hz, the first compensation transistor and the initialization transistor are turned on during a first time duration in N non-light-emitting periods per second, and the second compensation transistor is turned on during a second time duration in M non-light-emitting periods per second.
