Patent number: 11941209Abstract: Provides in the present disclosure are a touch module, a preparation method therefor, and a display device. The touch module is formed by means of attaching a polarizing function layer to a side of a touch function layer by a first bonding layer; attaching a cyclo olefin polymer (COP) film layer to another side of the touch function layer by a second bonding layer; and attaching a third bonding layer to a side, facing away from the second bonding layer, of the COP film layer.Type: GrantFiled: April 19, 2021Date of Patent: March 26, 2024Assignee: BOE Technology Group Co., Ltd.Inventors: Jiuzhen Wang, Meizhu Zheng, Lupeng Bian, Biao Gao, Zebang Guo, Xiongnan Zhang, Boyang Shi, Shengxing Zhang, Jian Cai, Dalin Xiang

Patent number: 9650708Abstract: A flat steel product having a tensile strength of at least 1200 MPa and consists of steel containing (wt %) C: 0.10-0.50%, Si: 0.1-2.5%, Mn: 1.0-3.5%, Al: up to 2.5%, P: up to 0.020%, S: up to 0.003%, N: up to 0.02%, and optionally one or more of the elements “Cr, Mo, V, Ti, Nb, B and Ca” in the quantities: Cr: 0.1-0.5%, Mo: 0.1-0.3%, V: 0.01-0.1%, Ti: 0.001-0.15%, Nb: 0.02-0.05%, wherein ?(V, Ti, Nb)?0.2% for the sum of the quantities of V, Ti and Nb, B: 0.0005-0.005%, and Ca: up to 0.01% in addition to Fe and unavoidable impurities. The flat steel product has a microstructure with (in surface percent) less than 5% ferrite, less than 10% bainite, 5-70% untempered martensite, 5-30% residual austenite, and 25-80% tempered martensite, at least 99% of the iron carbide contained in the tempered martensite having a size of less than 500 nm.Type: GrantFiled: May 16, 2012Date of Patent: May 16, 2017Assignee: ThyssenKrupp Steel Europe AGInventors: Jens-Ulrik Becker, Jian Bian, Thomas Heller, Rudolf Schoenenberg, Richard G.

Patent number: 8888934Abstract: In a method to produce formed steel parts a primary steel material is provided, which (in % by weight) comprises C: 0.02-0.6%, Mn: 0.5-2.0%, Al: 0.01-0.06%, Si: max. 0.4%, Cr: max. 1.2%, P: max. 0.035%, S: max. 0.035%, and optionally one or more of the elements of the “Ti, Cu, B, Mo, Ni, N” group, with the proviso that Ti: max. 0.05%, Cu: max. 0.01%, B: 0.0008-0.005%, Mo: max. 0.3%, Ni: max. 0.4%, N: max. 0.01%, and the remainder as iron and unavoidable impurities. The primary material is heated through at a heating temperature (TA) lying between the Ac1 and the Ac3 temperature, such that at best incomplete austenitising of the primary material takes place, is placed into a press-form tool and formed therein into the formed steel part. The formed steel part is then heated to a bainite forming temperature (TB), which is above the martensite starting temperature (MS), however below the pearlite transformation temperature of the steel.Type: GrantFiled: April 24, 2009Date of Patent: November 18, 2014Assignee: ThyssenKrupp Steel Europe AGInventor: Jian Bian

Patent number: 8449694Abstract: Disclosed is a method which allows steel strip to be produced in which high hardness and good formability are combined. The following steps of operation are followed: making the steel strip from the heat-treatable steel, heating the steel strip, when coiled into the open coil, to a decarburising annealing temperature which may be up to 20° C. below the Ac1 temperature of the given heat-treatable steel and which does not exceed the Ac3 temperature of the given heat-treatable steel, annealing the steel strip, in the open coil, in a decarburising atmosphere for a decarburising annealing time of at least 90 minutes, the decarburising gas which forms the decarburising atmosphere flowing through the gaps which exist between the layers of the open coil, accelerated cooling the steel strip, the depth of decarburisation, as measured from the given surface of the steel strip, being limited to a range which is less than a quarter of the thickness of the steel strip.Type: GrantFiled: August 7, 2008Date of Patent: May 28, 2013Assignee: ThyssenKrupp Steel Europe AGInventors: Jian Bian, Axel Grafen, Giovanni Sabatino
