    Abstract: The present disclosure relates to a display panel. The display panel may include a substrate. The substrate may include a display area, a dummy area inside the display area, and a boundary area between the dummy area and the display area on the substrate. The display substrate may further include an isolation protrusion on the substrate at the boundary area. The isolation protrusion may be configured to isolate a functional layer in the display area from the functional layer in the dummy area, and at least a side surface of the isolation protrusion facing the dummy area may be covered by an isolation inorganic layer.

    Abstract: The present disclosure relates to a touch display device including a display panel and a support structure. The display panel includes a display portion, a bent portion and a fixed portion. The bent portion is located between the display portion and the fixed portion, and the fixed portion is bent, through the bent portion, to a back side of the display portion. The support structure includes a first protective layer and a second protective layer oppositely arranged and located between the display portion and the fixed portion, a support layer located between the first protective layer and the second protective layer, and an adhesive layer located between the support layer and the second protective layer. The adhesive layer is provided with a structure configured to disperse stress generated by the display panel during bending.

    Abstract: 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.
