The display word-module data is input by single chip to display memory. The lightening process is accomplished by other circuit ( programme and drive) automatically. Dynamic display process engross a little of the time . The lighting is able to be adjusted by changing the resistance . The lighting ways: single , rolling from down , rolling from right.
