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 liquid crystal display (LCD) device includes an LCD panel with a number (N) of pixel elements for displaying an image. A dimming panel includes N dimming elements. The dimming panel has a first mode to apply a uniform dimming to the N dimming elements to provide a privacy function for the LCD device. The dimming panel further has a second mode to a apply a per-element dimming to provide a local dimming function for the LCD device.

An image forming apparatus includes a communication interface, a display, and a controller configured to, when the image forming apparatus is remotely connected with an information processing device via the communication interface, transmit, to the information processing device, screen data for causing the information processing device to display a same screen as a display screen being displayed on the display, when receiving remote access from the information processing device, perform display processing for the display screen in accordance with the remote access, and when the remote access is received while a particular screen is being displayed as the display screen on the display, impose a display restriction on the display screen.

A shared terminal includes: circuitry to control a display to display an image to a plurality of users, the plurality of users sharing a use of the shared terminal, and obtain, from a first privately-owned terminal owned by a first user of the plurality of users, first terminal identification information for identifying the first privately-owned terminal; a transmitter to transmit, to a terminal management server, an authentication request for authenticating the first privately-owned terminal to allow login of the first user into the shared terminal, the authentication request including the first terminal identification information of the first privately-owned terminal; and a receiver to receive an authentication result indicating whether the first privately-owned terminal is authenticated to allow login of the first user, from the terminal management server. When the authentication result indicates that the first privately-owned terminal is a legitimate terminal and login of the first user is successful, the circuitry controls the display to display a screen for allowing the plurality of users including the first user to draw an image. When the authentication result indicates that the first privately-owned terminal is not a legitimate terminal and login of the first user fails, the circuitry controls the display to display a screen with an error message.

A method and device for identity verification is provided. The method includes receiving a screen projection operation performed by a user to project a screen of a first electronic device onto a second electronic device, collecting, first identity verification information of the user in response to the screen projection operation, obtaining a first comparison result between the first identity verification information and second identity verification information pre-stored in the first electronic device, and displaying based on the first comparison result being consistent, a screen projection interface of the first electronic device, receiving an unlock operation performed by the user, collecting third identity verification information of the user, obtaining a second comparison result between the third identity verification information and the second identity verification information, and displaying or not displaying content based on the result of the identity verification.

In example implementations, a display is provided. The display includes an organic light emitting diode (OLED). An anode is coupled to the OLED and a thin film transistor is coupled to the anode of the OLED. A cathode layer is coupled to the OLED. An electrically controllable reflective layer is coupled to the cathode layer. An electrode layer is coupled to the electrically controllable reflective layer to control an amount of reflectivity of the electrically controllable reflective layer.

An image display system includes a first terminal device and with a second terminal device whose usable function range is smaller than a usable function range of the first terminal device. The image display system includes a display projection unit, a communication unit that establishes wireless connection with the first and second terminal devices, a control unit that manages the wireless connection, and a connection control image generating unit. The control unit and the connection control image generating unit generate a terminal connection image including information for connecting the second terminal device with the image display system, based on terminal connection permission information that assigns the second terminal device whose wireless connection with the display system is permitted, the terminal connection permission information being transmitted from the first terminal device. The display projection unit displays the terminal connection image.

An electronic device, an electronic system, and a control method are provided. The electronic device includes a display, a memory, and a processor. The memory stores an audiovisual module and a control module. The processor receives initial image information from an external electronic device through a bridge device. The processor is coupled to the display and the memory. The processor executes the audiovisual module to transform the initial image information with a first image format into transformed image information with a second image format, which is compatible to the display. The processor controls the display to display according to the transformed image information. The processor executes the control module to receive a control signal for operating the transformed image information, and provide the control signal to the external electronic device through the bridge device.

The present application provides a screen projection method, a receiving end device, and a sending end device. The receiving end device performs active wireless scanning and searching on the sending end device, and when the sending end device is scanned, establishes a wireless connection with the sending end device; and once the wireless connection is established, the receiving end device automatically sends a screen projection code to the connected sending end device, and the sending end device may prompt a user to perform a screen projection operation by means of displaying the screen projection code. In this process, there is no need for the user to perform complicated manual operations, the sending end device can automatically acquire the screen projection code, and prompts the user to perform the screen projection operation in a timely manner, thereby improving the timeliness of the screen projection operation.

An indirect operating system is suitable for a mobile electronic device to remotely operate a controlled device, and allows the mobile electronic device, after scanning a device barcode of the controlled device, to obtain a corresponding set of user operation pages from a background device and display it on a remote control interface shown by the mobile electronic device, and then, the mobile electronic device converts the user's operation on the user operation page(s) into a control barcode or a driving packet with identification information of the controlled device. Through the driving packet or control barcode, the controlled device can obtain the user's input information and operate according to the input information.
