Abstract: A quantum dot Light Emitting Diode, including an anode, a cathode, and a quantum dot light-emitting layer between the anode and the cathode, a carrier functional layer is arranged between the anode and the cathode. The carrier functional layer contains a magnetic material.

Abstract: The present disclosure discloses a subject matter message notification method performed at a terminal and to be disseminated to one or more target users. The method includes: displaying a subject matter editing interface, the subject matter editing interface including an editing item used for editing subject matter content, an editing item used for adding a target user, and an editing item used for adding a file; generating a subject matter message in accordance with user-provided subject matter content through the editing item used for editing subject matter content, one or more user-selected target users through the editing item used for adding a target user, and one or more user-selected files through the editing item used for adding a file; and sending the subject matter message to a server, wherein the server is configured to send the subject matter message to the one or more user-selected target users.

Abstract: Aspects of the disclosure provide methods and apparatuses for providing application interfaces. For example, a terminal device includes a display screen and processing circuitry. The processing circuitry displays, via the display screen, a fake interface for a specific application in response to a state change of the specific application. The fake interface displays non-privacy content that has no association with the specific application. Then, the processing circuitry detect an operation on the fake interface, and displays, via the display screen, an application interface of the specific application with privacy content when the operation on the fake interface satisfies a pre-defined requirement.
