20120042333 | Device and Method for Hierarchical Broadcasting - A hierarchical broadcasting device and method are disclosed. In the hierarchical broadcasting method, a broadcast transmitting device may transmit lower layer broadcast data for an existing broadcast to a broadcast receiving device via a first communication network, and may transmit upper layer broadcast data for an improved broadcast to the broadcast receiving device via a second communication network. In this instance, the broadcast receiving device combines the lower layer broadcast data and the upper layer broadcast data in order to display the improved broadcast. | 02-16-2012 |
20120138441 | KEYPAD ASSEMBLY FOR PORTABLE TERMINAL - A keypad assembly includes an operation member deformed according to user's manipulation to operate key switches, a binding member disposed on a top surface of the operation member, binding pieces extending and bent from the binding member to enclose sides of the operation member on an edge of the binding member, and a manipulation member disposed on a top surface of the binding member, the manipulation member including at least one key tops, in which the binding members are bound onto inner side walls of a housing of the portable terminal. | 06-07-2012 |
20130208090 | HIERARCHICAL BROADCASTING SYSTEM AND METHOD FOR 3D BROADCASTING - Disclosed are a hierarchical broadcasting system and method for 3D broadcasting. A hierarchical 3D image broadcasting method comprises: allowing a broadcast transmission system to transmit first broadcast data for an existing broadcast to a broadcast reception system via a first communication network; and allowing the broadcast transmission system to transmit second broadcast data for 3D image broadcasting to the broadcast reception system via a second communication network. At this point, the broadcast reception system enables the first and second broadcast data to be combined in order to display a 3D image broadcast. | 08-15-2013 |
20130208441 | KEYPAD LIGHTING DEVICE FOR PORTABLE TERMINAL - A keypad lighting device includes: a keypad member formed by an arrangement of plural key tops; at least one light emitting device arranged below the key pad member; and a light guide plate member arranged below the keypad member to light the key tops with light projected from the light emitting device. The light guide plate member is formed with at least one light-incident surface, to which the light projected from the light emitting device is incident. The light-incident surface is formed by a curved surface or plural inclined surfaces, and at least one of the normal lines of the light-incident surface is arranged to pass through the light emitting surface of the light emitting device. | 08-15-2013 |
20140015821 | METHOD OF DRIVING A DISPLAY PANEL AND DISPLAY PANEL DRIVING APPARATUS FOR PERFORMING THE METHOD - A display panel driving apparatus includes a first switching element and a second switching element. The first switching element applies first pixel data to a first pixel connected with a first data line of a display panel during a first sub frame period. The first switching element is connected with a data channel of a data driving part. The second switching element applies second pixel data having a level higher than a level of the first pixel data to a second pixel connected with a second data line of the display panel during a second sub frame period. The second switching element is connected with the data channel. Thus, display quality of a display apparatus may be enhanced. | 01-16-2014 |
20140085276 | DISPLAY DRIVING METHOD AND INTEGRATED DRIVING APPRATUS THEREOF - A driving method of a display device includes: determining each of a plurality of pixel rows of the display device as one of a motion picture display pixel row and a still image display pixel row by comparing image data of each of the pixel rows in a current frame and in a previous frame; and driving the motion picture display pixel row with a motion picture frequency and driving the still image display pixel row with a still image display frequency, which is lower than or equal to the motion picture frequency, where a plurality of still image display pixel rows are driven with at least two still image display frequencies. | 03-27-2014 |
20140307393 | ELECTRONIC DEVICE AND ASSEMBLY STRUCTURE THEREOF - An electronic device is provided that includes a front housing arranged in a front portion of the electronic device, and a bracket connected to the front housing, to which a plurality of electronic parts of the electronic device are affixed. The electronic device also includes a rear housing arranged in a rear portion of the electronic device and including at least one slider and at least one rail. Each of the at least one slider is connected to a respective rail. The at least one slider is slidable on and elastically supported by the at least one rail, without being released from the at least one rail. The rear housing is detachable from the bracket by the at least one slider. | 10-16-2014 |
20140313113 | LIQUID CRYSTAL DISPLAY AND DRIVING METHOD THEREOF - The described technology relates to a liquid crystal display and a driving method thereof. The liquid crystal display includes a plurality of pixels arranged in a matrix form. The pixels include a liquid crystal capacitor including a pixel electrode and a common electrode as two terminals. A plurality of data lines transfer data to the plurality of pixels. The pixels include a first pixel and a second pixel, which are adjacent to each other. First and second common signals are applied to the common electrode of the first and second pixels, respectively. The second common signal is inverted to the first common signal. The first and second common signals swing between a first voltage and a second voltage. The polarity of the data voltage transferred by a data line with respect to the first common signal or the second common signal is constant during one frame. | 10-23-2014 |
20140375627 | DISPLAY DEVICE AND DRIVING METHOD THEREOF - A display device and driving method thereof are disclosed. In one aspect, the display device includes a display panel displaying a still image and a moving image and a signal control unit controlling signals for driving the display panel and controlling a frequency of the display panel based on a low frequency enable signal. The signal control unit controls the driving of the display panel at a low frequency when the still image is applied to the display panel and the driving of the display panel at a normal driving frequency after a first time elapses. The signal control unit further controls the driving of the display panel at a low frequency after a second time elapses. | 12-25-2014 |
20150029645 | KEY BUTTON AND METHOD OF MANUFACTURING THE SAME - A key button and a method of manufacturing the same are provided. The key button includes an upper surface, a side surface formed at a certain height along a border of the upper surface, and at least two worked surfaces formed to have a certain slope in a boundary portion between the side surface and the upper surface, wherein at least one first worked surface and at least one second worked surface are formed such that a shortest distance between the upper surface and the side surface differs from each other. | 01-29-2015 |
