Apparatus for driving liquid crystal display
摘要:
A circuit for accepting serial data from a source meant for video display and displaying it on a liquid crystal display. The data is converted to parallel and is stored in address locations corresponding to four quadrants of a display screen. An input counter controls the writing of data to the memory, while an independent output counter controls the reading of data from the memory and its display on the liquid crystal screen display.
