The image on the left is your typical seven segment display with each of the segments labeled with the letters A through G. To display digits on these displays you turn on some of the LEDs. For example, when you illuminate segments B and C for example your eye perceives it as looking like the number “1.” Light up A, B, and C and you will see what looks like a “7.” Ok, so it isn’t rocket science :-)
For the hexadecimal digits A-F, you can do what looks like A, b, C, d, E, and F. Both B and D are lower case because they would otherwise be indistinguishable from 8 and 0 respectively.
