Abstract: A display apparatus, a user terminal and control methods thereof are provided. The display apparatus includes a signal receiver configured to receive a signal for one of a plurality of channels; a display configured to display an image of the one channel based on the received signal; a signal transmitter configured to transmit a signal to at least one user terminal; and a controller configured to, in response to the image being displayed on the display, control the signal receiver to broadcast a signal comprising channel information used for the at least one user terminal to receive additional information of the displayed image. With this, in providing the additional information of the image being displayed, user's convenience may be improved.

Abstract: The present invention relates to an optical thin film transistor-type fingerprint sensor, which comprises a backlight unit for irradiating light, including at least one of a red light source, the green light source and the infrared light source; and a photo sensor unit for sensing light irradiated from the backlight unit and reflected by a fingerprint of a user.

Abstract: A display apparatus, a remote controller and a control method thereof, the display apparatus including a first communication section which receives web page data including a plurality of link items, a receiving section which receives a video signal, a signal processing section which processes the web page data or the video signal, a display section which displays a web page corresponding to the processed web page data or a video corresponding to the processed video signal, and a control section which groups the plurality of link items included in the displayed web page into a predetermined number of groups, generates index information about the groups and the link items included in the groups, and displays first user selection icons corresponding to each group using the generated index information.

Abstract: Provided are a method and apparatus for providing a community widget at a first client device, the method including: receiving a client widget including authentication information from a server; searching a second client device in which the client widget is installed; performing mutual authentication with the second client device by using the authentication information; and transmitting, if the mutual authentication is successful, a community widget to the second client device.

Abstract: A capacitor capable of being formed in a vertical plane without an additional mask process and/or deposition process and a method of manufacturing the same are provided. The capacitor includes: a first conductive line formed on a substrate; a first interlayer dielectric including a first via hole formed at an upper portion of the first conductive line, and a second and third via hole pair formed at a region of the substrate; a first barrier metal layer and a contact plug formed in the first via hole; and first and second capacitor electrodes formed in the second and third via holes, respectively. The first and second capacitor electrodes and the first interlayer dielectric disposed between the first and second capacitor electrodes form a vertically constructed capacitor.
