Well, I'm partial to LED games that have the little line segments, like most of the Mattel sports games, and Coleco Elec. QBack. as opposed to the round LEDs. So there are quite a few that I really like. I didn't really have too many opportunities to play VFD games as a kid...mostly we had the LEDs. I still love those old LED watches and calculators! |

Yeah i have to say that you guys are rigth the slim LED's are sexier (can i really say this ). As a kid i was dreaming of having the Mattel Hockey (hey i'm Canadian this is OUR sport) but i ended up with the Entex version. Wich is probably why i have a soft spot for those round LED's.
Now that i have all (missing the soccer 2) the Mattel's ones, i can say that they are prettier. _________________ Keep on playing... no matter what ! |

I've been wondering this for a while. Are the round LED's and 'line segment' LED's a different technology or have the round ones just got a much bigger glass area?
Which was invented first? My first LED game was a 'line segment' type.

The first LED'S that were used as far as i know were the round ones, they used them in industrial compounds for machinery, for what exactly i'm not sure... _________________ Keep on playing... no matter what ! |

They are similar technology, but usually applied to the motherboard differently. Round LEDs are made like little light bulbs that are attached to the circuit board, while the line-segment type are usually manufactured right on the board. If you ever take apart a Mattel game, look closely at the display under a magnifying glass, you will see what I mean...
The round-types have been around since the early '60s (although some of the basic technology was first discovered in 1907). More than you ever wanted to know:
http://www.wavicle.biz/led_history.html
Now, the reason the Mattel games use the line-segment type is a little more interesting. Calculators in the 70s and early 80s all used LED displays with a different line-segment representing each of the 7 'parts' of a digital number 8. The first Mattel games were actually made from calculators that were re-programmed to function the way we all know. So, they just basically 'took apart' all the number 8's on the calculator display and re-arranged them into the Football (or whatever) pattern we all love so much.
That's also the reason you can't play the game and see your score at the same time: 70's calculators didn't have enough number 8's to represent that many line-segments at once, and they weren't about to re-design the circuitry.
