  • Patent number: 11005073
    Abstract: An OLED display panel and a manufacturing method of the OLED display panel are provided. A light-transmissive hole is in the OLED display panel, a blocking wall is arranged outside some sub-pixel regions around the light-transmissive hole, and a thin-film encapsulation layer is on the blocking wall. A portion of light emitted from the sub-pixel regions inside the blocking wall is reflected at an interface of the thin film encapsulation layer by total internal reflection to cause a bright light spot, so that an image can also be displayed in the light-transmissive hole. Therefore, an opening for an under-screen camera less affects aesthetics and appearance integrity of the OLED display panel.

  • Patent number: 10974233
    Abstract: The present invention provides a method for preparing 1,5-pentanediol via hydrogenolysis of tetrahydrofurfuryl alcohol. The catalyst used in the method is prepared by supporting a noble metal and a promoter on an organic polymer supporter or an inorganic hybrid material supporter, wherein the supporter is functionalized by a nitrogen-containing ligand. When the catalyst is used in the hydrogenolysis of tetrahydrofurfuryl alcohol to prepare 1,5-pentanediol, a good reaction activity and a high selectivity can be achieved. The promoter and the nitrogen-containing ligand in the supporter are bound to the catalyst through coordination, thereby the loss of the promoter is significantly decreased, and the catalyst has a particularly high stability. The lifetime investigation of the catalyst, which has been reused many times or used continuously for a long term, suggests that the catalyst has no obvious change in performance, thus reducing the overall process production cost.

  • Publication number: 20210095965
    Abstract: The disclosure relates to a tight-integrated navigation method assisted by Elman neural network when GNSS signals are blocked based on the tight-integrated navigation system model of the INS and GNSS. The dynamic Elman neural network prediction model is used to train the inertial navigation error model and the GNSS compensation model, so as to solve the problem of tight-integrated navigation when the GNSS signals are blocked. When the GNSS signals are blocked, the trained neural network is used to predict the output error of GNSS and compensate the output of inertial navigation, so that the error will not diverge sharply, and the system can continue to work in the integrated navigation mode. The low-cost tight-integrated navigation module is used, and the collected information is preprocessed to form the sample data for training the neural network to train the Elman neural network model.
