Abstract: A connection method, device, display apparatus, terminal apparatus and medium, are provided. The method includes: in the non-networkable case, generating a connection code based on connection information, so that a first screen-transmission application of a client terminal parses the connection code to obtain the connection information, and then establishes a connection between the first screen-transmission application and a second screen-transmission application through the connection information; and publishing service information, wherein the service information includes connection code and available connection information indicated by the connection code, so that when the client terminal cannot establish a connection based on the connection information, the client terminal is connected to the server terminal based on the service information.

Abstract: A data transmission method, device, conference system, wireless screen transmitter and storage medium are provided. According to the data transmission method, when the wireless screen transmitter accesses the terminal apparatus and performs screen transmission on the display apparatus, the privacy recognition program is quickly loaded from the wireless screen transmitter to the terminal apparatus. While transmitting corresponding media data to the wireless screen transmitter in real time according to current display screen, the terminal apparatus runs the privacy recognition program to recognize a privacy window in the current display screen and acquires corresponding position information, and then sends the position information to the wireless screen transmitter.

Abstract: A touch response method, device, interactive white board and storage medium are provided. The method acquires, based on infrared touch detection, touch operation data generated correspondingly by a current contact point on a writing interface. The touch operation includes a first touch operation and a second touch operation, and the first touch operation and the second touch operation are distinguished by the touch area. When there is only one touch operation, it confirms to enter a writing mode or an erasing mode according to a type of the touch operation.

Abstract: An exhibiting method of a desktop element and an electronic device are provided. The exhibiting method of the desktop element is applied to an operating system of the electronic device, a desktop of the operating system includes a desktop element, and the exhibiting method of the desktop element includes: receiving a set-to-top instruction directed at the desktop element; creating a floating-window container for the desktop element according to the set-to-top instruction; moving the desktop element from the desktop to the floating-window container; and locating the desktop element exhibited in the floating-window container on the upper layer of the interface exhibited in the desktop.
