An electronic device (18) is for managing the display of data to control a nuclear power plant. The data comes from a plurality of electronic control units (16A, 16B, 16C). Each control unit is configured to perform at least one action from among acquiring a value measured by a sensor (12A, 12B, 12C) and controlling an actuator (14A, 14B, 14C), the control units, sensor(s) and/or actuator(s) being according to several different nuclear safety classes. This electronic device (18) is able to be connected to the control units, and includes a set (25) of electronic module(s) (26A, 26B, 26C) for creating overlay(s) (28A, 28B, 28C). Each overlay contains information associated with one or several control units and according to a respective safety class; and a module (30) for generating a page (32) to be displayed, by superposition of several separate overlays.

A display device and screen displaying method are provided in this disclosure. The screen displaying method includes the following operations: detecting whether a noise signal on a conducting wire by a detecting unit; outputting a horizontal synchronizing signal and a data signal to a source driving circuit by a timing controller; wherein the data signal includes a first frame data voltage and a second frame data voltage according to the timing sequence; and receiving the first frame data voltage and the second frame data voltage by the source driving circuit, when the detecting unit is configured to detect the noise signal, the processor is configured to selectively output the first frame data voltage or the second frame data voltage.

The present disclosure provides a display system including a HMD mounted on a head of a user and a smartphone coupled to the HMD. The smartphone includes a touch sensor configured to accept a position input operation to detect coordinates of an operational position, a first sensor configured to detect a motion of the user with respect to the smartphone, and a first execution unit configured to execute personal authentication of the user based on a detection result of the first sensor until the user starts the position input operation.

Disclosed embodiments provide a temporary privacy mode for an electronic device. The user selects one or more regions of allowable content and/or unallowable content. The user then invokes a temporary privacy mode of the device. While the device is in the temporary privacy mode, only the allowable content is viewable on the display of the electronic device. The unallowable content is obfuscated or hidden from view. The third party therefore cannot see the content deemed private by the user. When the third party has completed review of the content, the user can exit the temporary privacy mode to return to normal operation.

A display device includes a first display configured to display information, a second display configured to display information, a display controller configured to determine the content of information to be displayed on each of the first and second displays and to display the determined information on each of the first and second displays, a first receiver configured receive an operation of a user; and a second receiver configured receive an operation of a user, wherein the display controller is configured to display predetermined information across the first and second displays in a case where the first receiver receives a predetermined operation, and the display controller is configured to display the predetermined information on the second display in a case where the second receiver receives the predetermined operation.

A method, system and computer-usable medium are disclosed for capturing an image rendered by a target application. One general aspect includes a computer-implemented method for capturing an image, the method including: intercepting API calls made by a target application to a graphics display driver, where the API calls made to the graphics display driver by the target application are made using a graphics rendering API library; and using the intercepted API calls to construct a copy of a frame buffer of the image, where the copy of the frame buffer is constructed independent of the graphics display driver. Certain embodiments may include corresponding stand-alone and/or network computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform one or more of these actions.

A method and an apparatus for providing a lock-screen are provided. The method includes turning off a display unit, configuring content for the lock-screen in response to the turning off of the display unit, receiving a user interaction, based on at least one button, turning on the display unit in response to the user interaction, and displaying the lock-screen that is changed based on the content configured to correspond to the user interaction when the display unit is turned on.

A backlight system controls a viewing angle in a switchable privacy display system that achieves a strong private mode and enhanced brightness in the private and public modes as compared to conventional configurations. The backlight system includes a first backlight unit that emits light from a non-viewing side of the backlight system toward a viewing side of the backlight system; a second backlight unit located on a viewing side of the first backlight unit that emits light toward the viewing side of the backlight system; and a privacy optic that includes a liquid crystal material and is located on a non-viewing side of the second backlight unit and between the first backlight unit and the second backlight unit, wherein the privacy optic operates to transmit light from the first backlight unit in a limited viewing angle range.

According to one implementation, a floating image display system includes a computing platform including a central processing unit (CPU), a graphics processing unit (GPU), and a system memory storing a software code. The system also includes one or more display screens controlled by the GPU, and a rotor coupled to the one or more display screens and controlled by the CPU. The CPU executes the software code to render a two-dimensional (2D) graphic on the one or more display screens using the GPU, and to spin the rotor and the one or more display screens about a vertical axis parallel to a display surface of the one or more display screens at a predetermined spin rate to generate a floating image of the 2D graphic. The floating image appears to be a three-dimensional (3D) floating image of the 2D graphic to a user viewing the floating image.

In one example, a display is described, which may include a plurality of spaced light emitting device packages, a privacy gate having partition walls to partition each of the plurality of spaced light emitting device packages, and a control unit to selectively move the partition walls up or down relative to the plurality of spaced light emitting device packages to control a viewing angle of the display.
