Abstract: PURPOSE: An LCD(Liquid Crystal Display) and a driving method thereof are provided to reduce a feed through voltage, thereby capable of solving the problem of quality deterioration due to the feed through voltage. CONSTITUTION: An LCD panel(22) has a pixel matrix. A gate driver(24) drives gate lines(GL1-GLn) of the LCD panel(22). A data driver(26) drives data lines(DL1-DLm) of the LCD panel(22). A timing control unit(30) controls a driving timing of the gate and data drivers(24,26). The timing control unit(30) generates gate control signals(DGSP,GSC,GOE) for controlling the gate driver(24) and data control signals(SSP,SSC,SOE,POL) for controlling the data driver(26). The timing control unit(30) generates and supplies dual start pulse(DGSP) having an interval of one horizontal period to the gate driver(24), so that the gate driver(24) generates a dual scan pulse. Also, the timing control unit(30) rearranges pixel data inputted from the outside and then supplies the rearranged pixel data to the data driver(26).

Abstract: 트랜지스터의 베이스에 인듐을 추가함으로써 바이폴라 실리콘 고주파 트랜지스터의 특성을 개선하는 방법이 기재되어 있다. 베타-얼리전압 곱을 개선하기 위해 높은 베타 및 높은 베이스 저항을 희생하여 기판내의 붕소를 인듐으로 교체하는 대신, 개별적인 붕소와 인듐 도핑 프로파일이 베이스내에 결합된다. 따라서, 순수한 붕소-베이스 트랜지스터의 가장 우수한 특성을 유지하지만, 인듐 프로파일의 추가로 인해 일부 파라미터가 개선되는 트랜지스트가 얻어진다. 이러한 "이중-프로파일" 또는 "인듐-증진형" 트랜지스터는 베타-얼리전압 곱 개선, 컬렉터-베이스 커패시턴스 스윙폭 감소, 및 낮아진 베타의 온도 의존성을 나타내지만, 순수한 붕소-베이스 트랜지스터의 유리한 특성을 유지한다. 이것을 안정되게 작동시키기 위해서는, 베타 및 유효 베이스 폭이 대체로 영향을 받지 않도록 인듐 프로파일이 붕소 프로파일내에 포함되어야 하는데, 이와 같이 이루어지지 않는다면 고주파 특성이 저하된다. 추가 인듐 주입의 잇점을 강조하는 어떤 기록된 파라미터와 함께 바이폴라 실리콘 고주파 NPN 트랜지스터를 제조하기 위한 보편적인 공정이 제시된다.
