Zusammenfassung:	A pixel circuit and a driving method are provided. In the pixel circuit, a driving circuit generates an on-current according to a lighting control signal. A first voltage regulator adjusts a voltage level of a first control terminal according to the lighting control signal, a third source driving signal, a first data voltage and a reference voltage, and generates a first driving current according to the voltage level of the first control terminal. A second voltage regulator adjusts a voltage level of a second control terminal according to the first, second and fourth source driving signals, a second data voltage and the reference voltage, and generates a second driving current according to the voltage level of the second control terminal. In a first operation mode, the magnitude of the on-current is the current value of the first driving current. In a second operation mode, the magnitude of the on-current is the current value of the sum of the first driving current and the second driving current.
