sixteen segment display is similar to seven segment and fourteen segment but this display is
used to display precisely numeric and character value .Each segment represent each LED .
There are two types of catagory common cathode and common anode . In common cathode all negative pins of each individual LED are made common as one pin called common cathode pins and other pin should be connected to VCC to to make it glow
Each pin have unique name and each pin should be connected to VCC in the case of common cathode and should be connect to ground in the case of common anode . for example to display star * pin i,j,k,l,m,n,g1,g2 should be connected to VCC and common cathode pin should be connected to ground as shown in figure below
To display something on sixteen segment display using microcontroller we need a special ic called driver or decoder IC which reduces wire connections . MAX6954 is one of the example of it you can search of it on google for more info but if you search on electronify we will promise to describe you detail about this on microcontroller sections .
