    Abstract: A pixel circuit and a driving method therefor, and a display panel. The circuit includes: a node control circuit, a driver, a display sub-circuit, a threshold compensator, and a reset device; the node control circuit outputs a reference voltage to a first node, or outputs a data voltage to the first node. The driver outputs a drive current; the display sub-circuit is configured to display a gray scale; the threshold compensator is configured to adjust a voltage of a second node to the sum of a voltage of a first level terminal and a threshold voltage of the driver, and adjust the voltage of the second node to a difference between the sum of the voltage of the first level signal, the threshold voltage of the driver, and the reference voltage and the data voltage; and the reset device is configured to reset the second node and the display sub-circuit.

    Abstract: The present disclosure relates to a pixel driving circuit, a display device and a driving method. The pixel driving circuit is configured to control on and off of a pixel unit, and includes: a first control sub-circuit, a first output sub-circuit, a second control sub-circuit, a second output sub-circuit, a third control sub-circuit, and a fourth control sub-circuit. Specifically, the fourth control sub-circuit is configured, if turned on, to cause a voltage drop of the first level signal input at the first level signal input terminal and to output the first level signal with the voltage drop to the third control node, such that a voltage at the third control node is less than or equal to a voltage at the first control node, thereby maintaining the third control sub-circuit off.

    Abstract: Embodiments of the present disclosure provide a pixel circuit, an array substrate, a display device and a controlling method thereof. The pixel circuit includes: a pixel display unit consisted of n sub-pixel display units, n≥3; and a data signal control unit coupled to the pixel display unit, n data lines for driving the pixel display unit and a control line. The data signal control unit is configured to, under a condition that a first control signal is input through the control line, couple the n sub-pixel display units to the n data lines for driving the n sub-pixel display units respectively; and when a second control signal is input through the control line couple one of the n data lines for driving the pixel display unit to at least one of the n sub-pixel display units in the pixel display unit.
