This application discloses a configuration update method for an LED display screen, a receiver card, an LED display module, and an LED display screen. The method includes: (S201) when it is detected that a receiver card is powered on, reading storage identity authentication data of the receiver card, and verifying whether the receiver card has been replaced; (S202) when it is determined that the receiver card has been replaced, outputting a configuration parameter stored in a memory to the receiver card, to update a configuration parameter of the receiver card; (S203) when it is detected that an LED display module is powered on, reading display identity authentication data of the LED display module, and verifying whether the LED display module has been replaced; and (S204) when it is determined that the LED display module has been replaced, outputting correction data of the LED display module to the receiver card.

Data privacy in screen sharing during Web conferencing includes selecting a third-party application executing in contemporaneously with a conferencing application. Screen sharing is activated during a Web conference in the conferencing application so as to share a display screen of the third-party application with different attendee computers over a computer communications network. An interface to the application is then queried with the attendees in order to receive access control data for the attendees. Then, a protected data field is identified in the display screen and determined whether one of the attendee computers is associated with one of several access control rules based upon the access control data that prohibits display of content in the protected data field. The data field is masked in the shared display screen for the one of the attendee computers while displaying remaining portions of the shared display screen in the one of the attendee computers.

A device capability discovery method and a P2P device are provided, and relate to the communications field and the distributed hardware field, to shorten time consumed to obtain capability information of a discovered device. A P2P device receives a probe request frame from another device. The P2P device returns a probe response frame including capability information of the P2P device. A device that receives the probe response frame can obtain a capability of the device in a device discovery phase. Alternatively, a P2P device sends a probe request frame including capability information of the P2P device to another device, so that the another device can obtain a capability of the device in a device discovery phase.

A scaler integrated circuit (IC) applicable to performing multi-picture processing in a display device includes multiple terminals, multiple Extended Display Identification Data (EDID) circuits and a control circuit. The control circuit receives a Multi-Stream Transport (MST) video stream from a video source through a first video input terminal, analyzes the MST video stream to generate a first Single Stream Transport (SST) video stream and a second SST video stream, sends the second SST video stream through a video output terminal to be a video output signal, and receives the video output signal through a second video input terminal, to allow the scaler IC to generate a combination picture according to the first SST video stream and the second SST video stream, for being displayed by a display output module within the display device.

A method for calibrating the color space on multiple displays in a computing system Includes determining a native color space for each of multiple displays; dynamically selecting a target color space to implement on each of the multiple displays based at least on part on the determined native color space of each one of the multiple displays; and instructing one of the multiple displays to map the associated native color space to the target color space.

An output apparatus includes circuitry to receive content data from a transmission source of the content data. The circuitry checks first format information for the content data to be output. The circuitry changes second format information of the content data to the first format information. The second format information is supported by a capture board. The capture board is connected between the transmission source and the output apparatus. The circuitry outputs the content data.

A processing method and its apparatus are provided in the present disclosure. The processing method includes obtaining a first display parameter of a first display; obtaining a second display parameter of a second display, where a first object is displayed by the first display and the second display, and determining a display adjustment parameter of the first object based on the first display parameter and the second display parameter, such that the second display adjusts display effect of the first object in the second display according to the display adjustment parameter; and a viewing angle of a second user viewing the first object on a side of the second display satisfies a first condition with a viewing angle of a first user viewing the first object on a side of the first display.

An improved browser application that provides a view with the option of displaying simultaneously content of a plurality of “tabs” of the browser application on one or more displays, regardless of whether the tabs are active or inactive, is described herein. For example, the browser application can display simultaneously the content of multiple tabs and allow a user to resize and reposition the content of any one tab independent of the size, position, or number of other displayed tab content. Thus, in some circumstances, the content of one tab can partially or fully overlap (and therefore partially or fully hide) the content of another tab after a user manipulation of the size or position of tab content.

Provided is a display apparatus having an LED module composed of a plurality of LED grids and mounted on a display panel; an LED driver module; a touch sensor mounted on the display panel; a control module configured to control an operation of the LED module; and a drawing device, assigned an identifier which indicates a unique color, and configured to grasp the grid coordinates of the LED grids corresponding to contact points with the display panel through light emitted from the LED module, wherein the control module receives the identifier assigned to the drawing device and the grasped grid coordinates from the drawing device, grasps position coordinates of the contact points through the touch sensor, specifies the identifier based on a comparison result between the received grid coordinates and the grasped position coordinates, and then displays a unique color at the contact point of the position coordinates.

A management apparatus includes a connection request transmitter transmitting, to a display apparatus, a connection request requesting video signal acquisition by the display apparatus for each input type of video signal, a connectability determiner determining whether a connection to the display apparatus is available using a connection response acquired from the display apparatus for each input type of connection request, and a connectable input notifier informing an input type determined to be connectable. The display apparatus includes a connection switching processor executing a connection operation for acquiring a video signal corresponding to a requested input type, a connection switching confirmer determining whether acquisition of a video signal corresponding to the input type is successful by the connection operation, and a connection response transmitter transmitting a connection response including a connection result indicating whether acquisition of a video signal is successful that is determined to the management apparatus.
