US11570182B1 Compute-less authorization
An endpoint determines whether a client is authorized to access data. A database stores separate authorizations of a permission model in a data table along with the data.

In response to the query, the database returns to the endpoint the requested data as well as an indication of authorization from the data table. The mapping templates of the endpoint are then used to generate an appropriate response to the client. When the database response indicates the client is authorized, the endpoint can return the requested data to the client. When the database response indicates the client is not authorized, the endpoint can return an error. In some embodiments, the endpoint is an application programming interface (API) gateway that conforms to representational state transfer (REST) software architecture.

A display apparatus includes: a substrate having a display area and a peripheral area outside the display area; a first conductive layer on the substrate in the peripheral area and comprising a first hole; a second conductive layer on the first conductive layer and overlapping the first conductive layer, the second conductive layer comprising a second hole; a planarization layer extending from the display area to the peripheral area and comprising at least two organic insulating layers between the first conductive layer and the second conductive layer; and a display element on the planarization layer in the display area, wherein a part of a portion of the second conductive layer except for the second hole is in contact with a part of a portion of the first conductive layer except for the first hole.
US11569475B2 Display device and method of manufacturing the same
A display device includes a display device including a substrate, and a display unit disposed on the substrate. An encapsulating unit encapsulates the display unit. The encapsulating unit includes a barrier organic layer. The barrier organic layer includes a plurality of organic materials and a plurality of inorganic materials. The inorganic materials are arranged in free volumes between the organic materials.
US11569465B2 Display device
In a display device including a flexible display panel, the risk of disconnection of a wiring due to bending is reduced. A display panel includes a display function layer including display elements and a wiring on one major surface of a base material having flexibility. The display panel includes, on the one major surface of the base material, an organic-film-covered wiring area where the surface of the wiring is covered with an organic planarization film that is an organic insulating film in direct contact with the wiring. The display panel includes, in the plane thereof, a display area where the display elements are arranged and a component mounting area that is a peripheral area located outside the display area. As the organic-film-covered wiring area, a curved area is provided in the peripheral area.
