how dot matrix multiplexing works

Hi eleynika my name is Tosin and i'm also a Nigerian. Your request depends on the system you are using. Row scanning or column scanning. Whichever one, it is simple. It simply depends on Persistence of Vision (POV) of the human eye. Flashing a light source beyond 60hz makes is seem on (an illuson). To display your data you simply assert the data on the column parallel, and select a row. This displays the data. switch to the next row while putting your data on the same column line. Continue doing these and the eye will se it as being stable. A microcontroller is very suitable for this or some combinational + sequential logic using a parallel eeprom. Hope this will be usefull info goodluck. my phone no is 08054905504
