Abstract:
A pixel circuit for an organic light-emitting diode (OLED) display is disclosed. In one aspect, the pixel circuit includes a current provider electrically connected to a current source and configured to perform a current sinking operation in response to a first scan signal and to adjust a driving current based on the current sinking operation. The pixel circuit also includes a digital driver configured to control a flow of the driving current provided from the current provider in response to a data signal and a second scan signal. The pixel circuit further includes a plurality of pixel selectors configured to provide the driving current received from the digital driver to an OLED in response to a third scan signal.
