Abstract

이 발명은 액정표시장치의 문자표시 반전 제어회로에 관한 것으로, 문자표시의 반전 여부를 명령어로 입력하여 그 입력된 명령어를 디코딩하여 사용자의 의도대로 간편하게 문자표시를 반전하여 액정표시장치로 출력되도록 하는 것을 동작상의 특징으로 하는 액정표시장치의 문자표시 반전 제어회로에 관한 것이다.The present invention relates to a character display inversion control circuit of a liquid crystal display device, which inputs whether the character display is inverted by a command and decodes the input command so that the character display can be easily reversed and outputted to the liquid crystal display device. The character display inversion control circuit of the liquid crystal display device characterized by the above-mentioned operation.
