LED board in python using tkinter,matrix and pixels : As a part of a python project I am trying to make an LED board using tkinter library.This board should receive an input (a sentence) and show it on the board.I have started by making 0 and 1 (6*7) matrix es for each letter but I really don't know what to do next and how should these letters be shown on the board

For example:

A=[[0,1,1,1,0,0],[1,0,0,0,1,0],[1,0,0,0,1,0],[1,0,0,0,1,0],[1,1,1,1,1,0],[1,0,0,0,1,0],[1,0,0,0,1,0]]

Letters should be shown as below
