Abstract: A pixel includes a switching transistor connected to a data line, a first circuit to control compensation of a first driving transistor, and a second circuit to control compensation of a second driving transistor. The first and second circuits are connected to the switching transistor. The first and second transistors are connected to respective organic light emitting diodes of a same pixel. Compensation of the first and second driving transistors is based on respective first and second subscan signals, which overlap periods of corresponding common scan signals to be received by the switching transistor.
