摘要： This disclosure relates to the field of display technologies, and discloses a thin film transistor, a method for fabricating the same, a method for controlling the same, a display panel, and a display device. The thin film transistor includes: a base substrate, a semiconductor active layer on one side of the base substrate, a source electrically connected with one end of the semiconductor active layer, a drain electrically connected with the other end of the semiconductor active layer, a gate insulated from the semiconductor active layer, the source, and the drain, and a modulation electrode insulated from the semiconductor active layer, the gate, the source, and the drain. The modulation electrode is proximate to the drain, and an orthographic projection of the modulation electrode on the base substrate overlaps with an orthographic projection of the semiconductor active layer on the base substrate

摘要： The present disclosure provides a pixel circuit and a driving method thereof, a display device. The pixel circuit includes a reset sub-circuit, a compensation sub-circuit, a data writing sub-circuit, a storage capacitor, a driving transistor, a light emitting control sub-circuit and a light emitting sub-circuit. The compensation sub-circuit may write a threshold voltage of the driving transistor into a gate of the driving transistor in a date writing stage, so that magnitude of a drive current output by the driving transistor is independent of the threshold voltage of the driving transistor in a light emitting stage.

摘要： Embodiments of the present disclosure provide a pixel circuitry and a driving method thereof. In the pixel circuitry, the reset circuit provides an initialization signal to a first node and one end of the light emitting device based on a reset signal. The driving transistor provides a driving current based on the voltage of the first node. The data signal write circuit provides a data signal to a third node based on a strobe signal. The compensation circuit couples a second node to the first node based on the strobe signal. The voltage supply circuit provides a first voltage signal to the second node based on a control signal. The control circuit provides a driving current provided by the driving transistor to the light emitting device based on the control signal. The light emitting device emits light according to the driving current.

摘要： The present disclosure provides an array substrate and and a repair method thereof. The array substrate comprises a first metal layer including a signal line; a first repair layer; and a first insulating layer. The first insulating layer is disposed between, and provides insulation between, the first metal layer and the first repair layer, and it is configured to be penetrable to allow the first repair layer to electrically connect the signal line to thereby repair connection weakness of the signal line. The first repair layer can comprise a first repair line, which is disposed over and along the signal line and is configured to be able to electrically connect two ends of a weak connection portion of the signal line through vias penetrating the first insulating layer.
