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.

A computer-implemented method may hide sensitive information, such as sensitive information relating to auto, home, life, or renters insurance, banking, and/or vehicle loans. In one aspect, the method may commence or execute an eavesdropper detection functionality or application. The method may also detect an unauthorized viewer or eavesdropper is viewing, or potentially viewing, a display screen associated with the mobile device for more than a threshold duration of at least one second, determine that sensitive or confidential information is being displayed or about to be displayed, on the display screen, and prevent the unauthorized viewer or eavesdropper from viewing the sensitive or confidential information via the display screen to facilitate hiding sensitive or confidential information.

A computer-implemented method may hide sensitive information including when no one is looking at a display screen of a client computing device, such as sensitive information relating to auto, home, life, or renters insurance, banking, and/or vehicle loans. In one aspect, the method may determine that confidential or sensitive information is being displayed on a display screen of a computing device of a user. The method may also collect image data from a front facing camera in communication with the computing device, and determine that zero or two or more people are viewing the display screen for more than a threshold duration of at least one second. The method may further blur or obscure the confidential or sensitive information being displayed on the display screen when it is determined that the zero or two or more people are viewing the display screen for more than the threshold duration.

A server includes a hardware platform, a hypervisor platform, and a virtual machine operating as an independent guest computing device. The virtual machine executes a remote graphics generation protocol to generate a bitmap to be transmitted for display on a client machine associated with the virtual machine, determine a protection label to be inserted within the bitmap, and determine an optimization technique to be performed on the bitmap. The remote graphics generation protocol also determines if the optimization technique, if performed, alters the protection label. If yes, then the protection label is inserted within the bitmap without performing the optimization technique. If no, then the optimization technique is performed and the protection label is inserted within the bitmap.

An information handling system operating an augmented reality assisted display security system may comprise a head mounted display device, a three-dimensional camera co-located with the head mounted display device capturing a three-dimensional image of a host display device displaying digital content, and a processor executing code instructions to determine a position and orientation of the head mounted display device with respect to a placeholder displayed by the host display device based on the three-dimensional image, generate a three-dimensional primitive of the head mounted display device and the placeholder based on the determined position and orientation, receive secure content, and render a three-dimensional image of the secure content within the placeholder primitive. The head mounted display device may display the three-dimensional image of secure content according to the three-dimensional primitive such that the rendered three-dimensional image of the secure content appears within the placeholder displayed on the host display device.

The disclosure relates to a method, electronic device, and non-transitory computer-readable medium for collecting fingerprints. The method includes detecting a touch operation on a fingerprint region; when the touch operation on the fingerprint region is detected, detecting a touch signal within the fingerprint region as a first touch signal; comparing the first touch signal with a preset report threshold to obtain a first comparison result; determining whether a fingerprint image on the fingerprint region is acquired based on the first comparison result; when the fingerprint image is acquired, analyzing the fingerprint image to obtain an analysis result; and outputting a prompt based on the analysis result.

A user terminal apparatus is provided. The user terminal apparatus includes a display consisting of a main display area disposed on a front side of the user terminal apparatus and a sub display area extended from one side of the main display area to be disposed on at least one area of a rear side of the user terminal apparatus, and a processor configured to provide a lock screen to a display area of at least one of the main display area and the sub display area and, in response to a user input of releasing the lock screen being sensed, control the display to provide a different home screen based on a display area where the user input is sensed.

The present invention comprises: a first region, having a display area for outputting images, for receiving touch input or acquiring fingerprint data by means of a touch entered on the display area; a touchscreen comprising a second region for receiving touch input; and a control unit for switching the first region from a touch receiving mode, which receives touch input, to a fingerprint sensing mode when a touch input is entered in the first region, wherein the touchscreen is provided with a touch sensor layer for receiving touch input at a first sense resolution in the touch receiving mode, and the control unit which, in the fingerprint sensing mode, switches the first region from the first sense resolution to a second sense resolution, which is higher than the former, so as to acquire fingerprint data, and maintains the second region at the first sense resolution so that the former receives touch input.

A device for generating restoration data by descrambling scramble data includes a linear feedback shift register configured to receive a first clock including a plurality of edges and sequentially generate a plurality of seeds including first to N1th seeds (where N is a natural number of 2 or greater) respectively corresponding to first to N1th edges among the plurality of edges, a seed calculator configured to calculate an Nth seed corresponding to an Nth edge among the plurality of edges by using the first seed, and a descrambler configured to descramble the scramble data by using the plurality of seeds generated by the linear feedback shift register and the Nth seed calculated by the seed calculator. The linear feedback shift register is further configured to generate an N+1th seed by using the Nth seed.

A display device is provided, which includes a controller, a display driver connected with the controller, a display panel connected with the display driver, a first barrier panel positioned above the display panel and a second barrier panel positioned above the first barrier panel. A plurality of first barriers arranged in parallel at intervals are distributed in the first barrier panel. A plurality of second barriers arranged in parallel at intervals are distributed in the second barrier panel. The controller is configured to send an image frame to the display driver. The display driver is configured to drive the display panel to display the image frame on display regions which are arranged in parallel at intervals. Each display region is configured to display a part of displayed contents in the image frame individually. The display device provides a wide-viewing-angle mode and a narrow-viewing-angle mode.
