Title: PIXEL COMPENSATION CIRCUIT, DRIVING METHOD, ORGANIC LIGHT EMITTING DISPLAY PANEL AND DISPLAY DEVICE
Abstract:
Disclosed are a pixel compensation circuit, a driving method, an organic light emitting display panel and a display device, comprising: a threshold compensation module, a storage module, a light emission control module, a driving transistor and a light emitting device. The threshold compensation module is configured to provide the voltage of a data signal end and a threshold compensation voltage to a control electrode of the driving transistor in a data write-in phase; the storage module is configured to store the voltage of the control electrode of the driving transistor in the data write-in phase and a light emission phase; and the light emission control module is configured to conduct between the second electrode of the driving transistor and the light emitting device in the light emission phase so that the driving transistor drives the connected light emitting device to emit light. By means of the mutual cooperation of the described three modules, compensation of the threshold voltage of the driving transistor is implemented by simple structure, simple sequence and less signal lines so that preparation technology is simplified, the production cost is reduced and occupied area is reduced, thereby facilitating the design of a high-resolution display panel.
