A communication terminal comprising circuitry to: receive selection of screen data, from among one or more items of screen data, as sharing target data to be shared with other communication terminal, each screen data to be used for generating a display screen and having been generated at the communication terminal; and share the sharing target data with the other communication terminal.

A method for presenting image content in two operating modes, B1 for a viewing mode with a restricted viewing angle, and B2 for a viewing mode with an unrestricted viewing angle, comprising: providing a first image generator radiating image content into a restricted viewing angle; providing a second image generator radiating image content into an unrestricted viewing angle, wherein the second generator is in front of the first, and is partially transparent to light from the first, and deflects, on at least 50% of its surface, at least 90% of the light passed by it, by maximally 10°; switching on the first generator to start mode B1, wherein the second generator is switched to a transparent state and scatters only a negligible portion of light from the first generator, to retain the restricted viewing angle; and switching on the second generator to start mode B2.

A display device employs a patterned quantum rod layer having pixel elements driven by pixel splitting to generate a privacy viewing mode. The display device includes a patterned quantum rod layer having first pixel elements including first quantum rods wherein the first quantum rods are aligned in a first alignment direction, and second pixel elements including second quantum rods wherein the second quantum rods are aligned in a second alignment direction different from the first alignment direction. An electronic controller is configured to perform pixel splitting whereby the electronic controller drives the first pixel elements and the second pixel elements such that the patterned quantum rod layer has an off-axis luminance different from an on-axis luminance to generate a privacy viewing mode. The first alignment direction may be oriented 90° relative to the second alignment direction.

A display device includes a display comprising a plurality of pixels. The display also has a plurality of regions. At least one of the plurality of regions is a protected region and the protected region includes at least one protection pixel. The display device also includes an image generator configured to receive a source image data for display content, identify a portion of the display content that includes sensitive data, and output the display content such that at least a portion of the protected region containing the sensitive data is displayed in at least one of a protection wavelength and a protection brightness.

Remote collaboration sessions may allow a local user to share their entire desktop or a single application with a remote user. By allowing each of a number of windows, but not all windows, to be selectively provided by the local computer to the remote computer, a more efficient collaboration session may be provided that does not require the local user to terminate sharing, when sharing a first application, then re-initiate sharing for the second application, just to switch between applications. Or, alternatively, alleviates the need to select the entire desktop that may comprise confidential information not to be shared. By allowing each, but not all, applications to be shared remotely and simultaneously, a remote user can be presented with relevant, but not excluded, application windows from the local computer.

Apparatuses, methods, systems, and program products are disclosed for securely presenting content on a display. An apparatus includes a processor and a memory that stores code executable by the processor. The code is executable by the processor to logically divide content to be presented on a display into a plurality of portions and randomly determine security display settings for each of the plurality of portions such that the plurality of portions are presented on the display with their respective security display settings at a frequency above a threshold of human persistence of vision but below camera shutter speeds. The code is executable by the processor to encode the randomly determined security display settings in metadata for each of the plurality of portions prior to the content being presented on the display and send the content, including the encoded security display settings, to the display.

A display device is provided. The display 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.

This disclosure provides systems, devices, apparatuses, and methods, including computer programs encoded on storage media, for a DPU enhancement that provides an improved HDCP user experience. A display processor may configure a plurality of frames for a display panel, where each of the plurality of frames may be associated with an authentication level. The display processor may determine whether the authentication level of at least one frame of the plurality of frames is greater than an authentication level of the display panel and, if the authentication level of the at least one frame is greater than the authentication level of the display panel, the display panel may skip/drop a transmission of the at least one frame to the display panel.

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.
