  • Patent number: 11954939
    Abstract: An electronic device (200) includes a liquid crystal display (LCD) panel (204), a cover layer (218), one or more light sources (224), and an optical sensor module (226). The LCD panel (204) receives a contact input associated with a fingerprint of a user. The cover layer (218) includes a first major surface (228) and a second major surface (230) opposite to the first major surface (228), and is disposed on the LCD panel (204). The cover layer (218) defines a first axis (AA?) normal to the first major surface (228). The optical sensor module (226) receives a light from the predetermined fingerprint sensing area (222) to detect the fingerprint. The optical sensor module (226) at least partially overlaps with the predetermined fingerprint sensing area (222) along the plane of the first major surface (228). The optical sensor module (226) defines a second axis (BB?) normal to a surface of the optical sensor module (226).

  • Patent number: 9303108
    Abstract: The present invention relates to a propylene-butene-1 random copolymer which has a butene-1 content of 1-6 mol % and a relative dispersity of butene-1, as determined according to NMR method, of greater than 98.5%. The propylene-butene-1 random copolymer of the present invention has a high relative dispersity of butene-1, as well as better transparency and heat resistance, so that it is more suitable for packaging food that may be edible after heating. Moreover, the copolymer has a lower xylene solubles content at room temperature. In addition, the present invention further relates to a method for preparing the copolymer and to a composition and an article comprising the copolymer.

  • Patent number: 9068030
    Abstract: The present invention provides a process for preparing high melt strength propylene polymer by direct polymerization, comprising that a propylene polymer with wide molecular weight distribution and containing “very high molecular weight fraction” can be prepared by controlling the species and ratios of the external electron donors in the Ziegler-Natta catalyst system at different reaction stages according to the requirement for different molecular weight fractions in the different propylene polymerization stage of the series operation, and said polymer has excellent mechanical properties, especially with very high melt strength. The present invention also provides a propylene homopolymer with high melt strength, comprising the following features: (1) the MFR is 0.2-10 g/10 min at 230° C. with a load of 2.16 kg; (2) the molecular weight distribution Mw/Mn is 6-20; (3) the content of the fraction with a molecular weight higher than 5,000,000 is higher than or equal to 0.
