Abstract
The present application discloses pixel circuit including a current-control circuit coupled respectively to a first data-signal terminal, a first voltage terminal, a first scan-signal terminal, and a first output node. The current-control circuit is configured to output a driving current to the first output node based on a first data signal and a first voltage signal in response to a first scan signal. The pixel circuit further includes a timing-control circuit coupled respectively to a second data-signal terminal, a second scan-signal terminal, multiple modulation-signal terminals, the first output node, and a second output node. The timing-control circuit is configured to select one modulation signal based on a second data signal in response to a second scan signal and to output the driving current from the current-control circuit via the second output node to a light-emitting device based on the modulation signal.
