A display apparatus, a control circuit, and an anti-peeping display method are provided. The display apparatus includes a display panel and a backlight module. The anti-peeping display method includes: determining an anti-peeping area; controlling the dimming diaphragm to be alternately switched between a transparent mode and a diffusion mode; in response to the dimming diaphragm being switched to the transparent mode, disabling a part of first light-emitting units rotating into the anti-peeping area from emitting light and enabling a part of second light-emitting units rotating into the anti-peeping area to emit light; and in response to the dimming diaphragm being switched to the diffusion mode, disabling the part of the first light-emitting units rotating into the anti-peeping area to emit light and the part of the second light-emitting units rotating into the anti-peeping area from emitting light.

An OLED display and an operation method thereof, which are capable of preventing malfunctions caused by the influence of external noise on an extended cable when a display panel is separated from a set part by a predetermined distance or longer, are discussed. The OLED display includes a timing controller embedded in the set part separated from the display module by a predetermined distance and configured to control a reset signal for cancelling a safety mode to be transmitted to the display module in order to prevent the safety mode from being abnormally maintained due to the influence of external noise on a cable used to connect the display module and the set part when the safety mode for displaying a black screen is executed, to thereby prevent the display from continuously executing the safety mode to consistently display the black screen.

Systems, devices, and methods are disclosed for enabling private communication between head-mounted displays. A first user dons a first head-mounted display. The first head-mounted display authenticates that the first user is authorized to view information displayed by the first head-mounted display. In response to positive authentication, the first head-mounted display displays the information to the first user. The first user inputs a selection command via an input interface, such as, for example, gazing at particular information, to select some of the displayed information. The first head-mounted display generates a message based on the user selection, which may be encrypted by the first head-mounted display prior to transmission. The first head-mounted display transmits the message to a second head-mounted display, such that the second head-mounted display displays the message to an eye of a second user wearing the second head-mounted display.

Embodiments of the present disclosure provide methods, apparatus, systems, computer program products for providing a virtual network within an interactive electronic technical manual system (IETM) configured to provide electronic and credentialed access via an IETM viewer to technical documentation for an item. In one embodiment, a method is provided comprising: receiving data from a graphical code as a result of a user scanning the code; and responsive to receiving the data: identifying virtual networks supported within the IETM that are available for the user to join and are associated with a specific object of the item; providing an identifier for each of the virtual networks; receiving selection of an identifier for a particular virtual network; and responsive to receiving the selection, joining the user to the virtual network so that content that is specific to the object associated with the virtual network is available to the user via the IETM.

An information processing device includes an openable display mechanism that displays a first screen in a first display region in a closed state and displays a second screen in a second display region having a larger area than the first display region in an open state, and a processor configured to execute a display process of lowering a visibility of the second screen when the display mechanism in the closed state changes to the open state.

A display device includes a display panel, an illumination device, and a control unit, in which, when performing display in a first display mode, the control unit corrects an image signal to generate a correction signal, writes a first image based on the correction signal in the display panel, leaves a second light source unlit, and selectively turns on a plurality of first light sources based on the correction signal, and when performing display in a second display mode, the control unit generates a correction signal, writes a first image in the display panel, leaves the second light source unlit, and selectively turns on the plurality of first light sources based on the correction signal, in a first display period, and writes a second image based on the image signal in the display panel and turns on at least the second light source, in a second display period.

A light-emitting device is provided. The light-emitting device includes a display panel including a substrate and a plurality of scan lines disposed on the substrate and extending in a first direction, a backlight module disposed under the display panel, and an optical film disposed above the backlight module and including a plurality of light-blocking portions and a plurality of light-transmission portions which are arranged alternately. The light blocking portions extend in a second direction, and the first direction and the second direction are not parallel.

A screen projection control method, storage medium and communication apparatus are provided. The screen projection control method includes: a screen projection receiving end receiving screen projection request information from a first screen projection sending end; determining, according to the screen projection request information, whether a third screen projection sending end that has triggered an interference-free mode of screen projection exists in at least one second screen projection sending end that is performing screen projection, wherein enabling the interference-free mode comprises stopping accepting a screen projection request; and if the third screen projection sending end that has enabled the screen projection interference-free mode exists, the screen projection receiving end sending response information for refusing the screen projection request to the first screen projection sending end.

A marking onto a collaboration board, located in a first location, is detected. The marking includes the creation of one or more content elements on the collaboration board. Responsive to detecting the markings one or more content elements on the collaboration board are analyzed. A first content element of the one or more content elements is classified based on analyzing the one or more content elements. The first content element is classified as a first privileged content element. The first location of the collaboration board is scanned. The scanning is based on the classifying of the first privileged content element. An unauthorized person is identified based on scanning the first location. The unauthorized person is not permitted to view the collaboration board. A security response is performed on the collaboration board regarding the one or more content elements. The security response is performed responsive to identifying the unauthorized person.

A color information extraction section extracts color information from image information. A luminance information extraction section extracts luminance information for controlling the luminance of a backlight based on the color information. A dithering section adds bits for dithering to the lower bit side of the luminance information and outputs the luminance information after the addition to a display apparatus as output luminance information. An image color correction section corrects the color of the image information based on the color information and outputs the corrected image information to the display apparatus as output image information. An upper bit comparison section compares upper bits of the luminance information, upper bits of the output luminance information, and upper bits of the output image information with each other.
