A control system for a switchable privacy display apparatus comprises sensors arranged to determine device location, operating environment, document type, application type and further comprises a privacy policy for control of privacy images. High image visibility is provided for public mode operation while in privacy mode a high visual security level may be obtained by means of control of image luminance, contrast and white point in response to the privacy policy.

A display device, a display control method, a non-transitory recoding medium, and a display system. The display device receives an image from a terminal device by wireless communication, outputs the image to a display, acquires operation information on the image being displayed at the display, and displays a first display component together with the image, the first display component for receiving an operation that executes to stop the output of the image and restrict transmission of the operation information to the terminal 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 screen corresponding to 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 control method includes detecting a first object within a first range corresponding to an output device, obtaining a first relative position relationship between the first object and the output device, and adjusting an output parameter of output light of the output device based on the first relative position relationship, to cause the output device to be in a first output state relative to the first object.

This disclosure relates to a display panel, a control method thereof, a display device and a display system comprising such a display panel. The display panel includes a plurality of pixel units. Each pixel unit has a plurality of subpixels Each subpixel has a display subpixel and an interference subpixel. Additionally, the interference subpixel and the display subpixel are different in at least one of color and gray scale. The display panel also includes a first control unit configured to control the display subpixel to be switched on during a first period of time in each display period, and to control the interference subpixel to be switched off during the first period of time in each display period and switched on during a second period of time in each display period.

Facial recognition-based authentication comprises obtaining a first image of a target object, updating projection information associated with a display by a display device, obtaining a second image of the target object, the second image being an image of the target object after the projection information is updated, obtaining an image difference data based at least in part on the first image and the second image, and determining whether the target object is a virtual object based at least in part on the image difference data.

A wireless device may disconnect a wireless connection to a remote device. The wireless device may include a memory device and one or more processors coupled to the memory device. The processors may generate a first wireless fingerprint of the wireless device, wherein the first wireless fingerprint comprises a first basic service set identification (BSSID) of a first access point to which the wireless device is connected. The processors may further determine if the BSSID of the wireless device is changed and if the BSSID is changed perform an active scan of a plurality of wireless channels. The processors may further generate a second wireless fingerprint for the wireless device based on the active scan and disconnect a wireless connection of the wireless device if the first wireless fingerprint is at least partially different from the second wireless fingerprint.

In a display device that is daisy-chained to a source device that outputs a video signal, and transmits an encryption key (KSV) used for encryption to source device, the display device includes storage to store the encryption key of an own display device (first device KSV), and the encryption keys (second device KSV, third device KSV) of all of downstream side display devices that are provided on a downstream side of the own display device among all of the other display devices that are daisy-chained, the encryption keys being transmitted to source device through its own display device when the display devices are daisy-chained to source device, and causes a display to form a split video image that is a part of a video image based on the number of splits of the video image corresponding to the video signal and the number of encryption keys stored.

A backlight source, a backlight module, a display device and a display system are provided. The backlight source includes a display light source and an interference light source; one frame time period is divided into a display time period and an interference time period; during the display time period, the display light source provides back light; and during the interference time period, the interference light source provides back light. The backlight can be applied to the display device, so that the display device possesses the anti-peeping function.

A method, system and computer program product for shielding objects from view are disclosed. In an embodiment, the method comprises detecting a specified presence around a given object; determining if the detected presence has authorization to view the given object; and when the detected presence does not have the authorization to view the given object, building a three dimensional holographic shielding image between the given object and the detected presence to shield the given object from the detected presence. In an embodiment, building the shielding image includes determining a position for the shielding image, and building the shielding image at the determined position. In an embodiment, a mobile communications device is used to build the holographic shielding image, and multiple cameras are installed in the mobile communications device to recognize placement of people in an area surrounding the given object.
