A circuit for fingerprint detection is disclosed. The circuit includes a transistor and a capacitor. The transistor includes a gate configured to, in response to a touch event of an object, sense a capacitance associated with the object. The capacitor, coupled between a first node and a second node, is configured to establish a voltage across the first node and the second node in response to a first control signal, and establish a compensation voltage at the first node in response to a second control signal. The transistor is configured to flow a current therethrough in response to a third control signal. The current has a magnitude independent of the threshold voltage of the transistor due to the compensation voltage.

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.

A parallax barrier, a display device and a display state control method belong to the field of display technology. The parallax barrier includes: a sealed cavity and a first polarizer disposed on a light exiting side of the sealed cavity, wherein the sealed cavity includes: a first substrate and a second substrate and a liquid crystal layer provided between the two substrates, a first transparent electrode layer is provided on a surface of the first substrate, and the first transparent electrode layer is a plurality of transparent electrode blocks arranged in an array, and a second transparent electrode layer is provided on a surface of the second substrate, and a voltage difference to deflect liquid crystal is capable of forming between the second transparent electrode layer and the transparent electrode block. By controlling different transparent electrode blocks, the parallax barrier can protect privacy in two directions.

A data processing system can store a long-term history of pixel luminance values in a secure memory and use those values to create burn-in compensation values that are used to mitigate burn-in effect on a display. The long-term history can be updated over time with new, accumulated pixel luminance values.

Disclosed is a smart folder device for displaying and copying digital content including: a screen folder on which digital content is displayed and including a folder structure having a cover front surface, a cover rear surface, a cover side surface, a cover first inner surface, a cover second inner surface, and a pocket surface; and a piece of screen paper which is implemented in a paper form in which digital content is displayed, is inserted between the pocket surface and the cover second inner surface of the screen folder, wirelessly communicates with the screen folder, and transmits digital content to the screen folder or receives digital content from the screen folder to store and display digital content.

A multi-display control apparatus includes a processor for an information handling device and a memory that stores code executable by the processor. The code is executable by the processor to detect a trigger event and, in response to detecting the trigger event, temporarily stopping display of content on a first display device in which the first display device is external to a second display device of a computing device storing the content.

Technologies for displaying public and private images includes a display device and one or more user viewing devices. The display device is configured to display or generate a personalized image or video that is viewable by an authorized user viewing device and not viewable by unauthorized viewing devices. To facilitate the display of the personalized images, the display device and the user viewing device(s) may negotiate a display protocol to be used by the display device to display the personalized image in a private manner. In some embodiment, the display device may also display a public image or video that is viewable by unauthorized viewing devices and/or individuals without viewing devices.

One embodiment provides a video transport system. The video transport system includes graphics processing circuitry to generate a video transport unit (TU) corresponding to a scan line of a first video frame that is unchanged from a second video frame, wherein the video TU includes a control sequence and an unchanged data payload corresponding to a defined number of pixels of the scan line of the first video frame. The video transport system of this embodiment also includes source tunneling bridge circuitry to generate a bus TU based on the video TU; the source tunneling bridge circuitry to parse the control sequence or the unchanged data payload of the video TU, and to generate the bus TU having a header that includes a field to identify the defined number of pixels of the unchanged data payload, and to eliminate, in whole or in part, the unchanged data payload in the bus TU.

An electronic device is disclosed. An electronic device comprises a display, a communication circuit configured to communicate with a first peripheral device, a memory configured to store first authentication information associated with the first peripheral device, and a processor, wherein the processor is configured to control the electronic device to: broadcast a first message via the communication circuit, receive a connection request message from the first peripheral device receiving the first message, authenticate the first peripheral device based on the first authentication information associated with the first peripheral device in response to the reception of the connection request message, and transmit screen data being displayed on the display to the first peripheral device via the communication circuit based on the authentication being valid.
