Abstract
The present disclosure relates to a pixel circuit, a driving method, an organic light emitting display panel, and a display device. The pixel circuit comprises: a threshold compensation sub-circuit, a capacitor sub-circuit, a light emitting control sub-circuit, a data writing sub-circuit, a driving sub-circuit, and a light emitting sub-circuit; the threshold compensation sub-circuit transmitting a reference signal provided by a data signal terminal to a first node, and transmitting an initialization signal provided by an initialization signal terminal to the light emitting control sub-circuit, connecting the light emitting control sub-circuit, the driving sub-circuit and a second node to store a threshold voltage of the driving sub-circuit through the capacitor sub-circuit under the control of a reset signal terminal; the light emitting control sub-circuit connecting the driving sub-circuit and the light emitting sub-circuit based on a light emitting control signal terminal to cause the light emitting sub-circuit to emit light.
