  • Publication number: 20240331629
    Abstract: Disclosed is pixel drive circuit including a light-emitting device electrically connected to a first power supply terminal and a second power supply terminal; a drive transistor having a gate electrically connected to a first node and a source and a drain electrically connected to second and third nodes; a first light-emitting control transistor having a source and a drain electrically connected to the first power supply terminal and the second node, and a gate configured to receive a first light-emitting control signal; and a second light-emitting control transistor having a source and a drain electrically connected to the third node and the light-emitting device, and a gate configured to receive a second light-emitting control signal. The first light-emitting control transistor is configured to transmit a first voltage signal supplied from the first power supply terminal to the second and third nodes at a node setting stage.

  • Patent number: 11019723
    Abstract: The present application discloses a stretchable electrode, an electronic device and a manufacturing method thereof. The stretchable electrode includes a substrate, an electric conductive area and an electronic device integration area; the substrate has a first elastic layer and a second elastic layer with different elastic moduli. The electronic device produced by using the afore-mentioned stretchable electrode can be stretched entirely, and when it is stretched, the electronic device would not be damaged and the variation of its impedance is small. Tests have shown that the electric conductive layer can be stretched by more than 20%, with the variation ratio of its impedance being less than 1.5%, and no damage is caused to the electronic device.
