  • Patent number: 12527209
    Abstract: A display device includes a first substrate and a second substrate facing each other; and a filling layer disposed between the first substrate and the second substrate. The first substrate comprises a support substrate comprising a display area in which emission areas associated with sub-pixels, are arranged; a light-emitting element layer disposed on one surface of the support substrate; and an encapsulation layer disposed on the light-emitting element layer. The encapsulation layer comprises a first inorganic layer covering the light-emitting element layer; an organic layer disposed on the first inorganic layer and overlapping the light-emitting element layer; and a second inorganic layer disposed on the first inorganic layer and covering the organic layer. A thickness of the first inorganic layer is smaller than a thickness of the second inorganic layer.

  • Publication number: 20240152585
    Abstract: A user access control method for an information system is proposed. The method may include processing login of a user using the information system, and acquiring a reference image obtained by capturing the logged-in user on the basis of a login time. The method may also include extracting reference feature information from the reference image and storing the reference feature information, and acquiring target images obtained by capturing a user using the information system at predetermined intervals. The method may further include extracting each target feature information from each target image; comparing each target feature information with the reference feature information to confirm whether or not each user using the information system at predetermined intervals is the same as the logged-in user, and controlling an access for the each user using the information system when the each user using the information system is not the same as the logged-in user.

  • Patent number: 11640993
    Abstract: A shielded gate trench MOSFET device structure is provided. The device structure includes MOS gate trenches and p body contact trenches formed in an n type epitaxial silicon layer overlying an n+ silicon substrate. Each MOS gate trench includes a gate trench stack having a lower n+ shield poly silicon layer separated from an upper n+ gate poly silicon layer by an inter poly dielectric layer. The upper and lower poly silicon layers are also laterally isolated at the areas where the lower poly silicon layer extends to silicon surface by selectively removing portion of the upper poly silicon and filling the gap with a dielectric material. The method is used to form both MOS gate trenches and p body contact trenches in self-aligned or non self-aligned shielded gate trench MOSFET device manufacturing.
