The present disclosure describes a method for displaying supplemental content. The method includes determining environmental characteristics, e.g., wall space, empty areas, colors, etc., for a display environment, determining supplemental content based in part on a primary content displayed by a primary display, and displaying the supplemental content in the display environment.

A display device includes a diode bridge configured to rectify input power; a power factor correction (PFC) circuit configured to control a power factor of the input power rectified by the diode bridge; a direct current (DC)/DC converter configured to change voltage of the input power received through the PFC circuit; and a PFC controller connected to the diode bridge and configured to selectively turn on or off the PFC circuit based on terminal voltages of lower diodes included in the diode bridge.

Embodiments provide for a handheld device with a unified desktop for integrating the functionality of the handheld device with a larger computer system. When connected to a peripheral display and/or a display of the larger computer system, the handheld device provides a unified desktop displayed across the screen(s) of the handheld device and the peripheral display. The unified desktop unifies the functionality provided by the larger computer system and the handheld functionality, e.g., communication applications (e.g., phone, SMS, MMS). A user can seamlessly interact with applications, e.g., open, move, close, receive notifications, on the unified desktop whether the applications are displayed on the screens of the handheld device, or the peripheral display of the larger computer system.

A dual display including: a first display for displaying first visual information and receiving a touch input; a second display including a double-sided emission display for displaying second visual information through a first surface or a second surface opposite to the first surface, and receiving a touch input; a sensor for sensing relative locations of the first and second displays; and a controller for determining whether or not the second display is covering the first display according to a signal of the sensor, and for controlling the first and second displays. Here, the controller is configured to receive the touch input from the second display when the second display unit covers the first display, and to receive the touch input from the first display when the second display does not to cover the first display.

A visibility improvement method using gaze tracking includes detecting a gaze of a user using a camera; determining a focus object at which the user gazes from among at least one object viewed through a display unit of an electronic device; and displaying, on the display unit, an image with high visibility that corresponds to the focus object and has higher visibility than the focus object.

A dual touchpad system is provided. The dual touchpad system includes a first touchpad and a second touchpad. The dual touchpad system also includes an input detection unit coupled to the first and second touchpads and configured to monitor the first and second touchpads for user contact thereon. The dual touchpad system also includes a gesture recognition unit configured to control an electronic device in response to receiving input from the input detection unit indicative of detected contact on the first and/or second touchpads to control the electronic device. The first touchpad is spaced apart from and is non-concentric with the second touchpad in embodiments.

A method and an apparatus for controlling an operation of a mobile terminal are preferably includes: cancelling a touch screen off mode and checking a set mode mapped to a certain key when input of the certain key is sensed while the mobile terminal is in the touch screen off mode. A screen is then displayed for executing the set mode, and displaying and processing of a signal input through a touch screen is performed. The method and apparatus provide an advantage by reducing procedures required by conventional devices in which a user process to execute a desired mode in a mobile terminal when the mobile terminal is in a touch screen off mode. By registering a function to be executed by input of one touch button key while in a touch screen off mode according to user tastes, the present invention accelerates utilization of the mobile terminal.

A display device can include a display panel, in which a subpixel including a transistor where data lines and gate lines intersect, is disposed; a gate driving unit that sequentially outputs a gate signal to the gate lines; a data driving unit that outputs a data voltage to the data lines according to the gate signal provided to each gate line, and outputs to the data lines during a blank time before a specific frame, data voltages having an output waveform that is identical to data voltages of at least one gate line of the specific frame; and a timing controller that controls the gate driving unit and the data driving unit, and performs a pixel compensation which changes data provided to each subpixel.

Methods and devices for selectively presenting a user interface in a dual screen device. More particularly, the method includes providing a gallery for the dual screen device. The gallery can present one or more images in a user interface. The gallery user interface can adapt to changes in the device configuration. Further, the gallery can display images or videos in the various configurations.
