Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A pixel comprising:
a display element configured to emit light during an emission period and comprising an anode and a cathode;
a first transistor comprising an upper gate and a lower gate and configured to control a magnitude of a driving current flowing to the display element;
a storage capacitor connected to the upper gate of the first transistor;
a second transistor configured to be turned on during a data writing period to transmit a data voltage to the first transistor;
a third transistor configured to be turned on during the emission period to transmit a driving voltage to a drain of the first transistor; and
a fourth transistor configured to be turned on during the emission period to connect a source of the first transistor to the anode of the display element,
wherein a lower gate-source voltage of the first transistor has a first voltage level in the data writing period and a second voltage level in the emission period.
