Provided is a light-emitting diode (LED) driving system. The LED driving system includes an LED current controller, a detector, and a system controller. The LED current controller is configured to control a current flowing through a plurality of LED arrays including at least one LED, such that no current flows through a first LED array from among the plurality of the LED arrays and a current flows through a second LED array from among the plurality of the LED arrays. The detector is configured to detect a sensing voltage from the first LED array. The system controller is configured to determine, based on a comparison result between the sensing voltage and a reference voltage, a failure of the at least one LED included in the second LED array.

Display system and self-checking method of the display system

A display apparatus with a radio frequency (RF) sensor and a user detection method using an RF sensor are provided. The display apparatus includes: a display panel configured to display an image; a support frame located in a back area of the display panel and configured to support parts of the display apparatus; and a radio frequency (RF) sensor configured to be arranged in the support frame for performing one of transmitting a radio frequency signal to a front area of the display panel and receiving the radio signal from the front area of the display panel, wherein the radio frequency signal which is transmitted or received passes through the display panel.

Display apparatus with RF sensor and user detection method using RF sensor

Disclosed are shutter glasses, a display apparatus, and control method therefore, which enables a user to control the display apparatus while wearing the shutter glasses. The shutter glasses include a communication unit which communicates with a display apparatus; a shutter which comprises a left eye shutter and a right eye shutter that are alternately open and shut; a sensor which senses a predetermined movement of the shutter glasses; and a controller which controls the shutter to be open and shut selectively based on a sync signal received from the display apparatus through the communication unit and corresponding to the 3D image, and controls the communication unit to generate and transmit a control signal controlling the display apparatus corresponding to the predetermined movement of the shutter glasses sensed by the sensor.

Shutter glasses and display apparatus including the same

A wireless rear speaker expanding apparatus which allows wired rear speakers to expand as wireless rear speakers by attaching a card-type wireless module in a home theater system includes a main body unit to reproduce a multi-channel audio stream from a recording medium, to extract a rear channel audio stream, to detect whether a transmission module unit is mounted, and to switch the rear channel audio stream to a wireless transmission mode or a wired transmission mode, a transmission module unit to modulate the rear channel audio stream extracted from the main body unit into a wireless signal and to wirelessly transmit the signal, if mounted as a detachable card-type unit on the main body unit, and a reception module unit to decode the rear channel audio stream wirelessly transmitted from the transmission module, and to amplify the decoded signal as a rear channel audio signal.

Disclosed are a display apparatus and a control method thereof, the display apparatus including: a signal receiver which receives a video signal; an image processor which processes the video signal received by the signal receiver; a display unit which displays an image on the basis of the video signal processed by the image processor; a function selector which senses a user's operation for selecting a plurality of functions provided by the display apparatus; and a controller which displays an on screen display (OSD) menu for selecting the plurality of functions on the display unit in accordance with a user's first operation entering within a predetermined distance from the function selector, and operates one selected among the plurality of functions in accordance with a user's second operation. With this, it is possible to provide an intuitive, convenient and reliable user interface for selecting a plurality of functions even under spatial limitations.

Display apparatus and control method thereof

A remote controller, a method of setting an operating mode thereof, and a method of determining a host device. The remote controller includes an angle detection unit to set a direction of an end of the remote controller to be a reference axis if a manipulation is input, and to detect a rotational angle between the reference axis and the front end axis of the remote controller if the remote controller rotates, and a controlling unit to control the remote controller to operate in an operating mode corresponding to the rotational angle.

Remote controller to set operating mode using angles, method of setting operating mode thereof, and method of determining host device

Provided are a user interface method of enabling a user to conveniently use a terminal allowing multi-tasking, and a computer readable recording medium storing the method. The user interface method includes classifying applications capable of being executed by the apparatus into groups, in such a manner as to classify one or more applications that perform similar functions into the same group; and displaying a window for executing a corresponding application, for each of the groups.

User interface method of multi-tasking and computer readable recording medium storing program for executing the method

A method for forming an integrated circuit isolation layer includes the steps of forming a patterned masking layer of a semiconductor substrate, forming an oxygen diffusing layer on the patterned masking layer and the exposed portion of the semiconductor substrate, and forming an isolation layer on the exposed portion of the substrate. In particular, the oxygen diffusing layer can be a layer of SiON, and the oxygen diffusing layer can have a thickness in the range of 30 .ANG. to 150 .ANG.. The oxygen diffusing layer and the mask layer can then be removed completing the isolation layer.
