An electronic device comprises a display having a display area, wherein a size of the display area visually exposed in a first state of the electronic device is reduced and a size of the display area visually exposed in a second state of the electronic device is enlarged, and a processor operatively connected to the display, wherein the processor may be configured to acquire state information of the electronic device, successively display a first preview image and a second preview images on the display, based on the state information of the electronic device, wherein the first preview image includes a first area of a specified image and corresponds to a preview image of a background screen in the first state, wherein the second preview image comprises a second area including the first area and a further area extending from the first area, and corresponds to a preview image of a background screen in the second state, and specify the image as a background screen, based on a first user input.

The system comprises a first data processing system, a second data processing system, and a server. The system further includes four screens. The first and third screen comprises a video stream and an audio stream. The second and fourth screen comprises a video stream displaying visual contents of a first document that is to be digitally signed by the first and second user. The first and second data processing systems are configured to receive a first and second unique signature from the first and second user, respectively, and add it to the first document. The server is configured to coordinate communication between the first and second data processing systems, record the visual contents of the first screen, the second screen, the third screen and the fourth screen, and store the recording.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for brightness control for under-display fingerprint sensor are disclosed. A method includes receiving, at a computing device, an indication to activate an under-display sensor that is located underneath a display of the computing device; activating a collection of LEDs of the display to provide illumination for the under-display sensor, including activating an LED in the collection of LEDs by: establishing, by drive circuitry of the LED, a first overdriven voltage across an LED-driving transistor that is arranged to energize the LED; establishing a second overdriven voltage across the LED-driving transistor; and establishing a steady state voltage across the LED-driving transistor; and activating the under-display sensor by reading a signal from the under-display sensor once the collection of LEDs has activated, including once the steady state voltage has been programmed across the LED-driving transistor.

An electronic device is provided. The electronic device includes a display and at least one processor operatively coupled to the display. The at least one processor may be configured to, when displaying content on the display, execute a personal information protection mode, identify a type of the content displayed on the display, copy the content into a plurality of frames, modify each of at least some of the plurality of frames based on the identified type of the content, and display a video obtained by merging the plurality of frames including the at least some modified frames on the display.

A system for managing collections having multiple content types can include a mixed-media collection (MMC) managing module to create an MMC incorporating previously captured screen data, an MMC storage module to store the MMC, an MMC rider module to generate a rider including additional data, and an MMC playback module to present to a user playback data and the rider, the playback data including the previously captured screen data that was incorporated into the MMC.

A system for a secure display module includes a display element array, a driver controller, a communication interface, a host controller and a cryptographic engine. The display element array includes one or more segments, and the driver outputs are configured to drive the one or more segments, respectively. The host controller is configured to send commands and data to the driver controller via the communication interface and the cryptographic engine is configured to encrypt communication data between the display element array and the host controller.

Systems and methods for intelligent display of content are disclosed herein. According to one illustrative method, a computing device camera captures an image of a face. The control circuitry determines, based on the captured image, whether at least a portion of the face is directed toward a computing device display. The control circuitry retrieves, from a memory, a rule specifying criteria for determining whether to block or permit presentation of content based on whether one or more faces are directed toward the display. The control circuitry determines, based on the rule and whether at least a portion of the face is directed toward the display, whether to block or permit the presentation of the content, and blocks or permits the presentation of the content via the computing device based on a result of the determining.

A source device for transmitting content to a sink device is provided. The source device may include an interface configured to perform high-bandwidth digital content protection (HDCP) authentication with the sink device, and a controller configured to determine an HDCP version supported by the sink device, convert the content so as to be encrypted in the HDCP version supported by the sink device in response to a determination that another HDCP version applied to the content is not supported by the sink device, encrypt the converted content in the HDCP version supported by the sink device, and control the interface to transmit the content to the sink device.

Methods and systems for providing an advanced hardware system for a self-service kiosk are disclosed herein. In specific embodiments of the invention, a payment interface device is provided. The device includes an integrated touch display, a means for receiving payment information, and a casing holding the integrated touch display and the means for receiving payment information. The device also includes an applications microprocessor and a secure microprocessor located within the casing. The applications microprocessor instantiates an operating system and stores instructions for execution by the operating system for operative communication with a peripheral bar code scanner and a peripheral display. The secure microprocessor stores instructions to encrypt payment information for the system and is in operative communication with the means for receiving payment information.

An electronic device, method and computer program product enable detecting user attention to dynamic content and enabling subsequent user access. The electronic device includes display device(s), a memory containing application(s) and a content monitoring supervisor (CMS) application, and a controller. The controller is communicatively coupled to the display device(s) and the memory and which executes the CMS application to configure the electronic device to perform functionality. The functionality includes retrieving content requested by the application(s). The functionality includes presenting at least a portion of the content on the display device(s). The functionality includes storing information associated with a particular portion of the content in response to determining that the particular portion has been viewed by a user of the electronic device for more than a time threshold. The functionality includes enabling access to the stored information by a second user in response to authenticating supervisory credentials of the second user.
