Abstract
A pixel compensation circuit including a light emitting diode, a drive unit, a control unit, a data write-in unit, a reset unit, and a pull-down unit is disclosed. The control unit is configured to control a voltage drop time of the first node according to a data voltage value received by the data write-in unit, so as to control a gray scale of the light emitting diode. The data write-in unit includes a first transistor, a second transistor, a third transistor and a capacitor. The first transistor is connected to a first voltage source and a second node. The second transistor is connected to the second node and a third node. The third transistor is connected to the third node and a data input source. The first capacitor is connected to the second node and a first reference voltage source.
