Abstract

액정구동장치에 있어서, 문자폰트롬으로부터 연속적으로 독출되는 두 문자의 문자폰트 데이타는 시프터에 의해 임의의 도트수에 의해 시프트되고, 시프트된 경과는 디스플레이되는 각 문자에 래치된다. 데이타 시프트 동작은 6도트 폰트 디스플레이 모드에서 수평방향으로 하나의 라인의 디스플레이 데이타(하나의 공통라인의 데이타)의 문자들간에 경계에 상응하는 블랭크 데이타를 제거하는 동안 수행된다.In a liquid crystal driving apparatus, character font data of two characters successively read out from a character font ROM is shifted by arbitrary number of dots by a shifter, and shifted progress is latched in each displayed character. The data shift operation is performed while eliminating the blank data corresponding to the boundary between the characters of the display data (data of one common line) of one line in the horizontal direction in the six-dot font display mode.
