It is a scrolling A on an led matrix.I wouldn't mind to put more alphabets but I haven't got the time and space for it.
Please be patient it takes time.

This application can be seen in buses(showing their next location),Trains(showing their next location) and shops or in a barbers shop!.It is something we come across everyday.Due to every circuit less space(no I'm not blaming them,it is impossible to have a very huge place for mobile devices) I could only manage to fit one alphabet.Usually we don't actually make a PCB or a circuit for this.It is done by using a software and you get ready made matrix board.If you're actually interested in making a scrolling text on your led matrix please use an Arduino.Also these led matrix are old as we would use them before 7-segment displays!Wow that would be tough!
Thank you
