Description: I was new, I am glad that this site through friends. Dynamic display is characterized by the all-digital segment select lines are connected in parallel, controlled by the bit line selection which a digital effect. As a result, it is not necessary for each one equipped with a digital latch, which greatly simplifies the hardware circuit. Highlight digital tube dynamic scan display. The so-called dynamic scanning display that turns digital sent to you glyph code and the corresponding bit option, the use of light-emitting tube afterglow and the role of persistence of vision of the human eye, people feel as if you are in the same digital tube display. Dynamic display brightness to be worse than the static display, so the choice should be slightly smaller than the current limiting resistor static display circuit.
