摘要： A display panel is described. Further, an electroluminescent display panel and a display device are described. By arrangement of a second signal bus line, a first end of a first signal line in a first display area in the display panel is electrically connected with the first signal bus line, and the second end of the first signal line is electrically connected with a first conducting wire in the second signal bus line, so that uniformity of a signal input by the first signal line in the first display area can be ensured. Therefore, the structure is not only the precondition of ensuring signal uniformity of the first display area, but is also the precondition of ensuring signal uniformity of a display area of the entire display panel.

摘要： The disclosure discloses a display panel, a display device, and a method for driving a pixel circuit, and the pixel circuit includes a data writing module, a light-emission control module, a driver control module, a threshold compensation module, an anode resetting module, a node initialization module, and an organic light-emitting diode. The threshold compensation module can compensate for drifting of threshold voltage of the driver transistor so that the pixel circuit can emit light and display while operating current of the driver transistor to drive the light-emitting element to emit light is only dependent upon a signal on the data line and voltage at a reference signal end, but independent of the threshold voltage and a first power source voltage end to thereby avoid the threshold voltage and an IR drop from affecting the current flowing through the organic light-emitting diode.

摘要： A pixel circuit, a drive method, a display panel and a display device are provided. A switch transistor is arranged between a first power supply signal and an input terminal (a source) of a drive transistor. When a drive circuit is at a second detection period during which drive current of a light emitting element is detected, the switch transistor is controlled to be turned off, such that the first power supply signal is disconnected from the source of the drive transistor. In this case, no current flows through the light emitting element, and therefore the light emitting element does not emit light, thereby solving a problem in the conventional technology that the light emitting element is lighted and it is not dark in a dark state when drive current of the pixel circuit is detected.
