    Abstract: A stretchable display panel and a display device are provided in the present disclosure. The stretchable display panel includes a plurality of display islands arranged in an array and a plurality of stretch bridges each connecting to two adjacent display islands, and further includes a display function layer and a touch control electrode layer. The display function layer and the touch control electrode layer are both disposed on a display island of the plurality of display islands; and an orthographic projection of the touch control electrode layer on the display island at least partially surrounds an orthographic projection of the display function layer on the display island.

    Abstract: Driving method for driving circuit, display panel, and display device are provided. The method includes: in a data writing stage, transmitting data signal voltage to a gate electrode of the driving transistor in response to a scan signal in a first scan signal line; in a light-emitting stage, turning on a driving path connecting the driving transistor to the light-emitting device, and making the driving transistor generate a driving current based on the voltage of the gate electrode in the driving transistor to drive the light-emitting device to emit light, in response to a light-emitting signal in a light-emitting signal line; and in a compensation stage, compensating the voltage of the gate electrode in the driving transistor by using a first power signal voltage. The light-emitting stage and the compensation stage overlap with each other, and a starting time of the compensation stage is after a starting time of the light-emitting stage.

    Abstract: Provided is a light-emitting element control circuit, a display panel and a display device. The light-emitting element control circuit includes a current source and at least one light-emitting unit, and the at least one light-emitting unit is connected in series to the current source. The at least one light-emitting unit each includes a first branch and a second branch which are connected in parallel. The first branch includes a first gating unit and a light-emitting element which are connected in series, and the second branch includes a second gating unit. The light-emitting element control circuit provided by the present application enables the current provided by the current source to pass through one of the first branch and the second branch in an active-selection mode, and meanwhile generation of photo-generated carriers in the light-emitting element can be avoided, thereby improving the display effect.

    Abstract: An organic light-emitting display panel, a display device, and an organic light-emitting display motherboard are provided. The organic light-emitting display panel includes a base substrate, a metal wire, a first insulation layer, and a conductive portion. The metal wire has an upper surface opposing to the base substrate. A material of the metal wire includes a first metal. The first insulation layer covers the upper surface of the metal wire and includes at least one hollow portion penetrating through the first insulation layer and exposing a portion of the upper surface of the metal wire. The conductive portion is electrically connected to the metal wire, and is not overlapped with the at least one hollow portion. A work function of a material of the conductive portion is G1, a work function of metal silver is G2, a work function of the first metal is G3, and G1>G2>G3.
