【Abstract】 The principle of static and dynamic drive mode LCD is introduced. Based on analysis of their drive waveforms,two methods of intercepting display information from lead fingers of the static and dynamic drive mode LCDs are presented. Tile actual circuit is described in detail. The experiment shows the methods are feasible.更多还原
