The method includes the steps of: displaying an active cell activating any one of a plurality of objects displayed on a screen; sensing a touch on a display screen; checking a position touched and a shift direction and a shift distance touched on a basis of the position touched by the user's finger; shifting a position of the active cell according to the shift direction and the shift distance touched; and performing an action of a corresponding object of an area of the active cell if a double tapping signal input on the display screen is sensed. | 01-01-2009 |
20090051667 | METHOD AND APPARATUS FOR PROVIDING INPUT FEEDBACK IN A PORTABLE TERMINAL - An input feedback method and apparatus in a portable terminal having a touch input device are provided, in which a user's finger contact on a screen having a plurality of objects displayed is sensed, a value sensed from the finger contact is compared with at least one threshold, and a vibration is generated in a different manner according to a comparison result. | 02-26-2009 |
20090103660 | DIGITAL BROADCASTING TRANSMISSION CAPABLE OF IMPROVING RECEIVNG AND EQUALIZING PERFORMANCE AND SIGNAL PROCESSING METHOD THEREOF - A digital broadcast transmitting system and a signal processing method thereof that improves the receiving performance of the system. A digital broadcast transmitter includes a randomizer to receive and randomize a transport stream into a specified position of which stuff bytes are inserted, a replacement sequence generator to generate known data including a predefined sequence, a stuff-byte exchange unit to insert the known data into the specified position of the transport stream into which stuff bytes are inserted, an encoder to encode the transport stream output from the stuff-byte exchange unit for an error correction, and a transmission unit to modulate the encoded transport stream, RF-convert the modulated transport stream and transmit the RF-converted data. The digital broadcast receiving performance is improved even in an inferior multi-path channel by detecting the known data from the received transmission and using the known data for synchronization and equalization. | 04-23-2009 |

20100073583 | FLANGE STRUCTURE FOR A PORTABLE TERMINAL - Disclosed is a portable terminal including a case having an opening that faces towards a user operating the terminal and a flange protruding towards the opening, a lower window having a partial surface that is attached to a lower surface of the flange, an upper window attached to the lower window to be exposed through the opening, and a liquid crystal panel placed under the lower window. The stress concentrated on and the likelihood of breakage of the flange structure of the portable terminal in which the case is connected with the window is thereby minimized. | 03-25-2010 |
20110141390 | CASE FOR PORTABLE ELECTRONIC DEVICE - A case for a portable electronic device includes an outer cover; a frame attached to an inner surface of the outer cover; a color converting liquid crystal display unit interposed between the outer cover and the frame; and an illumination unit interposed between the color converting liquid crystal display unit and the outer cover. The outer cover is made of a translucent or transparent synthetic resin. The color of the case seen from the outside can be changed by varying the color of the color converting liquid crystal display unit and the appearance or color of the portable electronic device can be expressed by controlling the illumination unit even in an environment in which intensity of illumination is weak, making it possible to provide various aesthetic effects to users. | 06-16-2011 |
20110175834 | TOUCH PANEL AND INPUT RECOGNITION DEVICE USING THE TOUCH PANEL - A touch panel is provided including at least one first electrode pattern including a plurality of electrode lines arranged in a first direction; and at least one second electrode pattern including a plurality of second electrode lines arranged in a second direction to intersect the first electrode lines; wherein the first electrode lines are spaced apart at different intervals from one another in the first direction. | 07-21-2011 |
