An apparatus, the apparatus comprising at least one processor, and at least one memory including computer program code, the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus to perform at least the following: based on the determined age of a particular message in a displayed message thread, provide for a change in the intelligibility of at least part of the particular message with respect to one or more of: at least one of the other of the messages in the displayed message thread; and at least some of the other part of the particular message.

The present disclosure provides a display panel, a method for driving the same, and an anti-peeping system. The display panel comprises a substrate; and multiple pixel units arranged on the substrate in an array, each of the pixel units comprising first self-luminous devices, second self-luminous devices, and quantum dot luminous devices, wherein the first self-luminous devices and the second self-luminous devices are stacked in various sub-pixel regions, the quantum dot luminous devices are disposed in at least two sub-pixel regions, and quantum dot luminous devices disposed in different sub-pixel regions have different luminous colors, wherein the first self-luminous devices are configured to excite the quantum dot luminous devices to emit light during a display period of one frame to display a normal picture, and the second self-luminous devices are configured to be in a turn-off state during the display period of one frame and excite quantum dot luminous devices within a part of the sub-pixel regions to emit light during an interference period of one frame to display an interference picture. The display panel according to the embodiments of the present disclosure realizes an anti-peeping function.

Briefly, a method for verifying the visual perceptibility of a display is provided. An intended message is written to a bistable display. Pixels that comprise portions of the message are measured and evaluated to determine if the message actually displayed on the bistable display was perceptible by a human or a machine. In some cases, information regarding the message actually perceivable from the display may be stored for later use. Responsive to determining that a message is perceivable or not perceivable, alarms may be set, one or more third parties notified, or additional display features may be set.

The present disclosure provides a display device, a display system and a display method. The display device includes a driver circuit, a display panel, and an interference unit arranged at a display side of the display panel. The driver circuit is configured to drive the display panel to display an image, and a time period for each frame of the image includes a display period and an interference period. During the display period, the interference unit is in a transparent state so as to enable light beams from the display panel to pass through the interference unit, and during the interference period, the interference unit is in an interference state so as to interfere with the light beams from the display panel.

Disclosed are various examples for selective screen sharing. In one example, a computing device determines an area to obscure within a video stream using screen-sharing data. The video stream is generated by applying a transformation to a screen capture. The transformation obscures the area within the video stream. The video stream is transmitted to a destination device. A user-specified modification to the area is obtained. The video stream is updated by applying an updated transformation to the screen capture that obscures the updated area within the video stream.

A system may produce images including narrow-bandwidth colors. One or more sets of the narrow-bandwidth colors may be selected to be interpreted as substantially a same color by a user. The system may include a light source configured to produce the narrow-bandwidth colors, and/or narrow-passband filters may create narrow-bandwidth colors from light emitted by broad-spectrum light sources or color sources. Spatial and/or time multiplexing may be used to create separate narrow-bandwidth colors interpreted as substantially a same color by the user. The light source and/or the narrow-passband filter elements may be adjustable and may alternate between emission of two or more narrow-bandwidth colors. A viewing device may include filters configured to selectively filter the narrow-bandwidth colors. The user may filter the narrow-bandwidth colors to separate a stereoscopic image pair, to view an image specific to a user, to view desired content obfuscated by an obfuscating image, and/or the like.

Disclosed is a mobile terminal using a display unit and a control method thereof. The mobile terminal includes a controller which displays first screen information corresponding to a first application on a first display region disposed on an inner surface when the mobile terminal is open, and converts the first screen information into second screen information when a folding event is generated. Further, the controller converts the first screen information or the second screen information into third screen information which is different from the second screen information when an angle between first and second regions of the first display region corresponding to the folding event is less than a reference value.

A pixel structure, including a first color pixel, a second color pixel and a third color pixel. The first color pixel includes a first-color normal-viewing sub-pixel and at least one first-color side-viewing sub-pixel. The second color pixel includes a second-color normal-viewing sub-pixel and at least one second-color side-viewing sub-pixel. The third color pixel includes a third-color normal-viewing sub-pixel and at least one third-color side-viewing sub-pixel. First color light emitted from the first-color normal-viewing sub-pixel, second color light emitted from the second-color side-viewing sub-pixel, and third color light emitted from the third-color side-viewing sub-pixel are mixed to obtain a white emission in a first side view direction.

A system including a reader and an information terminal is provided. The information terminal displays an information code, while the reader optically reads the information code. The reader includes an emission unit and an imaging unit. The emission unit emits light in a predetermined emission state when the information code is imaged by the imaging unit. The information terminal includes an imaging unit, a control unit and a display unit. The control unit of the information terminal drives/controls the display unit to display the information code only when the predetermined emission state is imaged by the imaging unit. That is, unless the predetermined emission state of the emission unit of the reader is imaged by the imaging unit of the information terminal, the information code is not displayed on the display unit of the information terminal. Thus, security in reading the information code is further improved.
