Led lights?

wow... umm... yeah..

They make surface mount LED displays. I'm not sure what you're not clear about?
 
to put it in computer terms you might remember they're like the old displays that used to say what speed your computer was running at.

or another example would be it's just like the display for most digital alarm clocks. except thin....with very small leads...
( read :pain the arse to solder):D
 
lol

i. have. no. f*cking. idea. that site is crap? all i can guess is maybe the "non-leads" are built so that the pins fit right into a breadboard?! heh... good luck decripting that...!!
 
Are you asking what kingbright does? They make leds and led products.
 
An SMD (Surface Mount Device) does not solder "through" the board with leads of any kind. It attaches to the board with tiny solder pads that are on the surface of the board, hence the name "surface mount". Yes, they are very much a PITA to solder without the prpoer tools, solder, and working conditions.

A through-hole component DOES solder to the board with leads, hence the name "through-hole".

SMD components are generally smaller than through-hole.

To see an example of SMD and through-hole parts, just look at any motherboard. The big tall capacitors, connectors, and any large components are through-hole. You can verify it is through-hole by looking at the back-side of the board and seeing the 2 (or more) leads sticking through. All of the tiny resistors, ICs, and other small components are all SMD.

what is it exactly that you're trying to do with them? or did you just find the link somewhere and click on it? all they are are just little glowing numbers...

damm!t, i have to go to school tomorrow. ever get that feeling where you probably should go to sleep, but you just really don't want to? that sucks. :)
 
They display numbers. If you want to display numbers and don't want to mess with the LCD + controller, there you go. Some of the Epox boards (8KHA+) used these to display the motherboard status.

Fuck I know the feeling. I need to be studying for my russian test tomorrow but I just got back from dumpster diving(got a 30gig wd:D, but I don't think my russian prof cares ).
DRJ: the point of the smd led displays is that a manufacturer can solder these directly to a complex circuit board. When you use smd components you can make the pins much smaller and much closer together, therefore you can make the devices themselves smaller. With these led displays it doesn't make much of a size difference since they need to be a certain size for visibility, but they do help because they only use one side of the circuit board instead of two.
 
http://www.mouser.com sells Electronics Components. that display isn't something you plug into your USB port or something, it's simply a 7 segment display, which are found in digital alarm clocks, etc... that's all that is. you have to build a circuit to drive the display in order to make it do something. hell, you could make an alarm clock display out of those if you wanted too... or you could use them for some computer mod...

point is, that's just the display, one component, needs alot more to do something.

it's like asking what a resistor is used for... anything.

awwww gotcha now. so basically there kinda a waist of money.

ya i just found them on this website and wondered what they where

No. If you don't have a use for these then of course it would be a waste of money, like it would be a waste of money to buy an airplane if you can't fly. Some people will have a use for these products and so it is not a waste of money for them. Like I said, these smd displays only use up one side of a circuit board. That is an obvious advantage and may ease trace routing and reduce board complexity, so the extra cost of these may be canceled out by using a smaller circuit board or something.
 
And don't forget that all SMD devices are machine mountable. Very few, if any through-hole parts are machine mountable.

Oh yeah I knew there was something else but I couldn't think of it. That alone is probably enough to justify any cost difference.
