    摘要： A mobile terminal having a QWERTY key layout and a method of setting and inputting a symbol therein are provided. The method of setting a symbol in a mobile terminal having a QWERTY key layout includes selecting a setting function of a symbol defined a user; adding, if the selected setting function comprises an addition function, a selected symbol to a key mapping table, deleting, if the selected setting function comprises a deletion function, a selected symbol from the key mapping table, and changing, if the selected setting function comprises a change function, a selected symbol to another selected symbol. Therefore, symbols frequently used by a user can be viewed in one screen, thereby minimizing steps for searching for a desired symbol. Further, a symbol set by the user can be immediately determined by displaying symbols mapped to each key of a key input unit with a QWERTY key layout, and thus a character including a symbol can be easily input, thereby improving user convenience.

    摘要： An apparatus and method for driving a liquid crystal display device are disclosed in which the response speed of the liquid crystal can be increased without using a digital memory. The driving apparatus includes a liquid crystal panel with gate lines and data lines arranged perpendicularly to each other, a gate driver that supplies a gate pulse to the gate lines, and a data driver. The data driver samples an input N-bit digital data signal to generate an analog data voltage, generates a modulated data voltage for acceleration of a response speed of the liquid crystal according to an M-bit data value of the sampled digital data signal, mixes the modulated data voltage with the analog data voltage, and supplies the mixed data voltage to the data lines.

    摘要： A driving circuit of an LCD device contains a driving circuit. The driving circuit includes a digital-to-analog converter that outputs a first data signal by converting a digital data signal to an analog data signal; a modulator that outputs a second data signal by modulating the amplitude and pulse width of the first data signal; and a combiner that combines the first data signal with the second data signal. The combiner provides the combined data signal to a data line of an LCD panel.
