This patent relates to a mobile terminal and a method of controlling an operation of the same. The method of controlling an operation of a mobile terminal includes displaying a file list and scroll arrows for scrolling the file list on a touch screen. When the scroll arrow is touched and entered, the file list is scrolled at a scroll speed previously set in response to a time when the scroll arrow is touched and entered. A vibration signal to identify at least one of a scroll speed and a current scrolling position of the file list is provided. Accordingly, when a file list is scrolled, a scroll speed or a current scrolling position can be easily identified by a tactile sense.

Mobile terminal and method of controlling operation of the same

A mobile terminal and controlling method thereof are disclosed, by which group communications of various types with a conversation group can be performed in various ways can be performed in a manner of forming the group of conversation with at least two counterpart terminals using an image including at least two character pictures. The method includes displaying an image including at least two character pictures on a display unit of the mobile terminal, if the at least two character pictures in the image are selected, searching a memory of the mobile terminal for contact information respectively related to the selected character pictures, forming a conversation group with the searched contact information, and performing group communication with the conversation group.

Mobile terminal and controlling method thereof

A mobile terminal including a touch screen and a method of controlling an operation thereof are provided. The method of controlling an operation of a mobile terminal includes: displaying a thumbnail image corresponding to an image file on a touch screen to be randomly overlapped; selecting any one of thumbnail images by touch input; and displaying the selected thumbnail image together with an option icon for selecting a quick menu to be distinguished from other thumbnail images. Therefore, a list of stored image files can display thumbnail images in a new arrangement manner and it possible to quickly enter a related menu from the thumbnail image.

Mobile terminal including touch screen and method of controlling operation thereof

A method of controlling a mobile terminal and which includes displaying a first screen image on a touch screen of the mobile terminal as an idle background screen, receiving a touch and drag input operation being performed on the touch screen including the displayed first screen image, and displaying a second screen image corresponding to a direction of the touch and drag input operation, said second screen image corresponding to a new idle background screen.

Mobile terminal and method of controlling the mobile terminal

A plasma display panel is disclosed. The plasma display panel includes a first panel including address electrodes, a first dielectric layer, and a phosphor layer formed on a first substrate, and a second panel bonded with the first panel by interposing barrier ribs therebetween, the second panel including a plurality of transparent electrodes and bus electrodes, a second dielectric layer, a first protective layer containing magnesium oxide doped with a crystalline oxide, and a second protective layer containing crystalline magnesium oxide.

Plasma display panel and related technologies including method for manufacturing the same

The present invention relates to a plasma display panel comprising an electrode pad. The plasma display panel of the present invention comprises an electrode formed in a first region of a substrate, and an auxiliary pad and an electrode pad formed in a second region of the substrate. Therefore, since adhesive force between the auxiliary pad and the electrode pad is improved, a phenomenon in which the electrode pad are fallen off can be prevented.

Plasma display panel comprising electrode pad

Disclosed is a plasma display panel. A plasma display panel according to an embodiment of the present invention comprises a front substrate and a rear substrate attached to each other with a predetermined distance therebetween, a plurality of barrier ribs disposed between the front and rear substrates creating a plurality of discharge cells, and a plurality of scan electrodes and a plurality of sustain electrodes which are alternately arranged in each discharge cell. The plasma display panel has the enhanced discharge efficiency and emission efficiency. Further, the plasma display panel can be manufacture at low cost.

Plasma display panel

An internet telephone communication system including a voice transmitting and receiving parts and a method of operating the system are disclosed. The voice transmitting part retransmits voice data packets at least once through an internet network according to a retransmission frequency information packet received from the voice receiving part. The voice receiving part transmits the retransmission frequency information packet to the voice transmitting part in order to request to retransmit the voice data packets R times, where R is determined based a data loss rate calculated. By retransmitting the voice data packets, the transmitting rate of the data and the corresponding VOIP conversation quality are greatly improved.

Apparatus and method for internet telephone communication

The present invention relates to a VoIP (Voice over Internet Protocol) system and a method for preventing data loss in the same. A receiving system in the VoIP system decides a hold time corresponding to the loss rate of compressed voice data, and provides the hold time to a transmission system. The transmission system adjusts voice input speed depending on the hold time. Therefore, the transmission system can regulate compressed voice data generation rate therein not to exceed a designated channel capacity.

VoIP system and method for preventing data loss in the same

The present invention relates to an internet telephone and a method for recovering voice data lost in the internet telephone. Whether there is any voice data lost in a voice data packet received via the internet network and the position information for a lost portion of the voice data is obtained. A voice data normally received previously to the lost portion is filled in the lost portion of the voice data. In making a telephone call using the internet, the speech quality is improved by correcting the lost voice signal.
