  • Patent number: 11935460
    Abstract: A shift register and a display panel. The shift register includes an output adjustment module, a trigger write module, and a node adjustment module. A first terminal of the output adjustment module inputs a first clock signal. A second terminal of the output adjustment module inputs a first power signal. The output adjustment module is configured to adjust the shift register to output the first clock signal or the first power signal according to the signal on a first control node and the signal on a second control node of the output adjustment module. The trigger write module is configured to write a trigger signal to the second control node according to the clock signal of the control terminal of the trigger write module. The node adjustment module is configured to adjust the signal on the first control node.

  • Patent number: 10763449
    Abstract: An OLED display panel is provided. The OLED display panel comprises a first electrode; an opposite second electrode; and a plurality of stacking layers sandwiched between the first electrode and the second electrode. The plurality of stacking layers at least comprises a first auxiliary light-emitting layer and a light-emitting layer sequentially disposed on the first electrode. The first auxiliary light-emitting layer comprises a host material and a dopant material, and the dopant material comprises a compound of the following chemical formula (I): where n is an integer equal to or larger than 1, X1, X2 and Xn+2 each independently has a chemical structure of R? is selected from any one of a substituted aryl group and a substituted heteroaryl group, and a substituent in the substituted aryl group and a substituent in the substituted heteroaryl group each includes at least one electron acceptor group.
