sorry Pro=2006 police scanner..lol

[Barakuda318]

Hello Jeri, I've been very curious about electroluminescent displays every since I had to repair My Radioshack Pro-2003 display backlight (which is EL) I am in my First Year of Electronics Engineering at ITT Tech and was thinking of doing some display work with EL. Problem is the EL displays that you can purchase for repairing. seem to not last that long (eventually die out completely) and seem to dim quite alot over time. my ? is do these inks last long? and is EL improving any at all?...

[kavic5150]

Hi Jeri, your videos are great, keep them coming. I'm looking for a small el panel driver that will light up a 24cm square panel at its maximum brightness using a 350ma lipo cell. I'm not worried about shortening the life of the el panel a bit. Got any advice?

[jutsmyface]

I am very happy to see the vidoe from you, hopefully the others also are happy for You Jeri shows how to make electroluminescent (E) displays with etched circuit boards and Luxprint EL ink

You are very intelligent !!

[davegt27]

Wow a chick that can build race cars and design electronics. Hats off

[AccessNo]

Thank you! :)

[AccessNo]

For how long will that light ?

[jeriellsworth]

@AccessNo EL has a life in the thousands of hours.

You got a perty mouth

[theonelinerkid]

these are good..i could never do ything like this......i havent got a tecnical bone in m body lol

[tetrisfrog]

Oh, awesome! never knew it was this simple OR that DuPont sold electoluminescent "inks". Thats badass! Thanks for the video =]

[iBradleyAllen]

very cool Jeri ! very interesting

[tontop217]

Hi I am a fan of yours here in Philippines.

Can you give what materials and how to make a EL Panel.

i want this for my project in school... coz i want to make a PAROL(Chrismas Lantern)....cos i want this to submit in this september....Salamat (thank you)

[bitmerge6502]

I'm thinking of using a microcontroller to generate an AC signal. then you could vary the frequency and use PWM to modify brightness.

[rwilkus]

What range of supply voltage were you using? Thanks!!

[jeriellsworth]

@rwilkus EL lights up around 90v - upward. At a certain point your dialectric will breakdown. I didn't measure, but I'm guessing this is between 100v-200v

[KarriKoivusalo]

Could this stuff be made to work on a regular ink jet, or would the paint be useless if made thin enough to run through the jet mechanism? I have a sneaking suspicion the actual printer costs a fortune...

[jeriellsworth]

@KarriKoivusalo The particle size seems pretty big for an ink jet, but maybe a dusting scheme where the inkjet deposits the binder.

[gollumondrugs]

@jeriellsworth In that case could you screen print the inks?

[gfxlonghorn]

So on the first light display, did you use a phosphor and a transparent conductor or was there simply a layer of tin oxide which functions as both a phosphor and a conductor?

[CanaaniteRanger]

I love this GIRL :-)

[superdau]

Could you pull a resistive touchscreen apart and use the sheets as the transparent electrode (and bare copper as the other)? I don't know what the resistance of those screens is, but supposedly the substrate is polyester, which is also a good dielectric used in capacitors. So you could place them conducting side up (protect with varnish or something else transparent), connect it with all around for lowered resistance. the only thing to worry would be to get uniformly distributed phosphor.

[Blogapult]

Sorry to comment on the burn't out pixel, but wanted to leave a tip: it seems like it would be really easy (and fun!) to write a quick video post processor (for say Virtual Dub, or whatever video editing suite you use, assuming it has a plug-in architecture) that would blend that pixel out of your videos... You should give it a shot!

[lexichronicle2]

imagine how titz it'd be to open some gear up and discover the awesome face glowing all over the board.... awesome

[DickMohawk1]

so many words I didn't understand here

[shodanxx]

I wonder ..

how much power does it consume per inch² ?

how long before it burns out ?

@DusteDdekay

I thought the "winding up" noise from the power supply was nice in a mad scientist powering up the doomsday device kind of way



[frogz]

we are not worthy!!!

*bows down*

btw, you know how to fix a lcd with a stuck pixel? you flash alot of bright colors very fast

but... what most people dont know, it also works with ccds!

google rgb.swf and have your cam try to record it for 5 min

[jeriellsworth]

@clone4crwproductions It was not tap of any kind. 

[fanprograms]

Jeri.  Great job!

Aaron

[timmeh87]

You're cute ;)

[pivotraider1]

@timmeh87 Keep dreaming little boi!

[Gameboygenius]

@timmeh87 Cute? While you're right, that's the least relevant comment you could possibly post to this video. (Excluding Skyrim jokes.)

[AiFiLTr0]

Thanks a lot... I'll surely get down to it once I finish repairs to my pcb manufacturing rig.

[necromncr]

Let's start a donation for Jeri's camera!

[rasz]

you can get rid of the burned pixel in post, just use one of the video editing programs and apply a filter to cut it out, and average blank spot with values from the neighbeing pixels, thats how camera manufacturers fix it (in the firmware)

[StripeyType]

This is *precisely* the sort of thing I was talking about in my comment on your earlier video. Kudos!

[TookMe20min2findThis]

Thanks for the demo. First time I see this.

I hear the life time is about a 1000 hours! If this is true, that isn't much for real life applications I'm afraid

Btw, I'm curious if exposing the stackup to white light could somehow affect the circuit? Simply put, could this stuff be used to detect light also (as an LED could?) Perhaps would the capacitance be slightly different with or without light exposure where this could be used for building huge touch screen panels?

[Bytebored]

This is awesome, I have been thinking about making a small, rather high dpi display using an oLED array, but this looks like more fun, and it's cheaper.

Now let me shoot some questions:

I see you only use dielectric ink and antimony tin oxide, and since I live in Europe I don't think I'm going to buy the kit.

Could you tell me which dielectric is used, or could be used (I'm thinking glue) and what the concentration is of the ATO?

And what voltage/frequence do you use / energy does it need?

[DusteDdekay]

Let's do an EL clock :P I don't like the noise from the inverter though, it's a pain in the ear =(

[jeriellsworth]

@DusteDdekay The noise is from the power supply and can be eliminated. I like the clock idea.

[treborrrrr]

Set up a PayPal account and ask for new camera donations. I promise you'll have a new camera in no time and some change for parts as well.

As for the actual content. I would absotootly LOVE an EL Game&Watch game. If it weren't for my fear of high voltage I'd give it a go for sure.

[Tyrannous]

you have some EL on your face

[Intosia]

lol @ the pixel :D

[drOffset]

It would be fun to use two 4051s with their 8 channels connected in a matrix, then use the A,B,C pins to make dots of light bounce around. Wouldn't need LEDs then!

[Nashblackcat]

This is awesome ! Jeri your such an inspiring person. Now have no excuse but to try this.

[frac]

I might actually consider sending you a new camera if you have something reasonable in mind. Do you have an Amazon wish list?

[frac]

@frac Hmm. Fancy zooming feature. Might be out of my price range, but who knows.

[jeriellsworth]

@frac Just giving you a hard time. I'd like to get a new camera, but one with nice zoom is a little expensive, when I have other nerd toys to buy.

[RAYGproductions]

Nice.

[kinglonewolf104]

Thats cool, expecially the 2nd one which is much brighter.

Do I remember those games?! I have around 20 of them up in our attic - including Cave Man, Munch Man (Pac Man clone), Firefox, Scramble among others :)

[trailkeeper]

maby some "copper tape" can also used for making lighted segments

[alphabeets]

Damn cool! Jeri, you rule. So does the electroluminescent material eventually deteriorate and urn out? What gets "used up" in that stuff?

[jeriellsworth]

@alphabeets It does have a limited life, but it lasts years.

[kenatiod]

Jeri, you could flip your work area around so the dead pixel does not end up in such a noticeable place. Later, you could write a quick program that averages the pixels around that one to get a value that blends in better.

[jeriellsworth]

@kenatiod Ah Ah Ah! I said you have to send me a new camera if you complain.

[acousvnt]

What if kenatiod wrote that program *for* you, then would it still be considered a complaint?

[Trihedralguy]

Jeri keep up the good work!

[vk2zay]

I can see a lot of fun projects based on screen printed EL displays... Wonder if they will ship the phosphors out here to Oz?

[secobi]

your dead pixel is pretty cute :3

[nathanallan1]

Cool! I can definitely see potential for this in a LOT of ways!

BTW that's a HUGE display you held up, I am impressed :)
