Abstract:
The present disclosure provides a pixel including a first transistor, a second transistor, a third transistor, a fourth transistor, a capacitor, and an OLED; the second transistor and the third transistor are turned on in the first period to charge the capacitor with a data current, until the current flowing through the second transistor is 0 and the current flowing through the first transistor is the data current, the capacitor stores a voltage corresponding to the data current; the fourth transistor is turned on in the second period to cause the OLED to emit light, and the voltage stored by the capacitor corresponding to the data current causes the current flowing through the OLED to coincide with the current flowing through the first transistor in the first period. The present disclosure can make the current flowing through the OLED not change with the threshold voltage of the driving transistor.
