  • Patent number: 10923512
    Abstract: The embodiments of the present disclosure provide an array substrate, a preparation method thereof, and a display device. The preparation method of an array substrate comprises: forming the active layer, a gate insulating layer, the gate metal layer and the patterned photoresist sequentially on a substrate; forming a gate electrode transition pattern by etching a gate metal layer via a patterned photoresist, using a wet etching process and a dry etching process sequentially; and doping an area of the active layer not sheltered by the gate electrode transition pattern with ions to form a heavily doped area of the active layer.

  • Patent number: 10916565
    Abstract: The present disclosure provides a field of display technologies, and in particular, to a LTPS substrate and a fabricating method thereof, a thin film transistor thereof, an array substrate thereof, and a display device thereof. The LTPS substrate, able to be used for the fabrication of a thin film transistor, includes a light shielding layer, the light shielding layer mainly composed of amorphous silicon doped with a lanthanide element. The present disclosure mainly employs an amorphous silicon film layer doped with the lanthanide element as the light shielding layer of the LTPS substrate, which not only ensures the light shielding efficiency but also reduces the production process, and further prevents the occurrence of the H explosion problem due to H exuding during the ELA process.

  • Publication number: 20190339670
    Abstract: A system and method is provided for facilitate lattice structure design for additive manufacturing carried out through operation of at least one processor. The processor may be configured via executable instructions included in at least one memory to receive a three dimensional (3D) model of an object. The processor may also receive effective mechanical properties for at least a portion of the 3D model to be filled by a lattice producible by a 3D printer configured to produce the object. In addition the processor may determine lattice design parameters based on the received effective mechanical properties for the portion of the design. Or in the opposite direction, the processor may determine the effective mechanical properties based on the lattice design parameter. Further, the processor may modify the 3D model to include the lattice having the determined lattice design parameters for the portion of the 3D model.
