Abstract
A pixel structure including a first switching transistor, a setting unit, a capacitor, a driving transistor, a second switching transistor and a luminous element is disclosed. The capacitor is coupled between a first and a second node. The first switching transistor transmits a data signal to the first node according to a scan signal. The driving transistor includes a threshold voltage and a gate coupled to the second node. The second switching transistor includes a gate receiving an emitting signal. The luminous element is coupled to the driving transistor and the second switching transistor in series between a first operation voltage and a second operation voltage. The setting unit controls the voltage levels of the first and the second nodes to compensate the threshold voltage of the driving transistor.
