Patent number: 11731396Abstract: A deformable structure includes a first deformable layer, and a material of the first deformable layer includes a deformable material. The deformable material includes a plurality of sheet structures that are stacked, and each sheet structure includes a plurality of aldolases. A molecular model of an aldolase is equivalent to a square on a plane where the sheet structure is located, and the aldolase has amino acid residues at each of four corners thereof. In one sheet structure, amino acid residues at four corners of each aldolase are connected to amino acid residues of four aldolases around the aldolase through four disulfide bonds, respectively. In two adjacent sheet structures, amino acid residues of two adjacent aldolases are connected through at least one disulfide bond.Type: GrantFiled: February 27, 2020Date of Patent: August 22, 2023Assignees: BEIJING BOE DISPLAY TECHNOLOGY CO., LTD., BOE TECHNOLOGY GROUP CO., LTD.Inventors: Junli Zhou, Qiang Li, Liangliang Zhao, Pingli Li, Qingyan Zhang, Yang Liu, Chunli Jie, Xiuli Liu, Yanqiu Li, Kaipeng Fu
