  • Cleaning apparatus and cleaning method
    Patent number: 10710126
    Abstract: A cleaning apparatus and a cleaning method are provided. The cleaning apparatus is used for removing a residue on a substrate, and includes: a deformable device arranged on the substrate; and an excitation device configured to generate an excitation source for the deformable device, so as to enable the deformable device to be deformed under the effect of the excitation source, thereby to drive the substrate to vibrate and enable the residue to fall off from the substrate.
    Type: Grant
    Filed: May 11, 2017
    Date of Patent: July 14, 2020
    Assignees: BOE TECHNOLOGY GROUP CO., LTD., HEFEI BOE OPTOELECTRONICS TECHNOLOGY CO., LTD.
    Inventors: Yangkun Jing, Fei Liu, Zhiwei Xu, Xiaopan Che, Chuanhui Chen
