Abstract:
1. A display system, comprising: a scan driver providing at least one scan signal; a data driver providing at least one data signal; and at least one pixel comprising: a switching unit controlling a level of a first node according to the scan signal; a driving unit having a threshold voltage and coupled to the first node; a luminescence unit coupled to the driving unit in series between a first operation voltage and a second operation voltage; a storage unit coupled between the first node and a second node; and a controlling unit controlling a level of the second node, wherein during a first period, the level of the first node is equal to a first reference level, and the level of the second node is equal to a second reference level, wherein during a second period, the level of the first node is equal to a third reference level, and the controlling unit makes a voltage difference between the levels of the first and the second nodes to be equal to the threshold voltage of the driving unit, wherein during a third period, the level of the first node is equal to the data signal, and wherein during a fourth period, the driving unit lights the luminescence unit according to the voltage difference between the levels of the first and the second nodes.
