Turn LCDs into Electroluminescent Displays - Luxprint Experiments

Jeri experiments with Dupont Luxprint Electroluminescent inks and converts an old LCD into a simple EL display. She also demonstrates that super glue can be used as the dielectric and that zinc sulfide glow powder does not work well as an EL phosphor.

The phosphor emits light at 3:40 for those accusing me of not showing a working device.

So the plastic that ur putting it on, is just normal plastic???

[jeriellsworth]

@natester632 This can be made with normal plastics, but it needs an additional transparent ink layer. I've made a video about the stack up layers.

I think a quick diagram with the layers would help to shown how this all works. Nice video though. Thanks.

[jeriellsworth]

@hugohugo37 I have videos with the full stack up of layers.

@telesniper2 What do you mean? I show the LCD glass lighting up at the end. I have about 6 EL videos showing devices.

hey jeri your videos are amazing! i was thinking about how you showed the standard glow powder doesnt work - theres a pdf on the jon beck site saying the luxprint phosphor has copper and silver, and that the silver helps create a matrix that the ac electric field can shoot electrons and holes into for recombination. could this be something that the standard glow powder is missing? im just wondering what would happen if you stirred a small amount of silver paint into ZnS:Cu ?

"LCD goo"

LOL!

i almost fall on the flour because of laughing !

@ jeri... i m curious to know how this flexible EL turned out to be a flexible RBG display panels which are currently under a prototype but soon going to release. i wanted to make a flexible wall display where i can have atleast a vision like normal LCD monitors. it would nb

It would be nice if you could make a "Star Trek" console display. i.e. Mr. Spock's Science Scanner. I think it is known a Moire' pattern ??

@jeriellsworth what are the vacuum displays that you showed at 1:56? Where could I find them and do they need a few hundred volts to run them like the others in the video

[vambreace]

ah! ha ha. thanks for the info i was thinking the E.L. manufacturers was using some type of special or custom made chemical for the effect. i never think you can do electro luminescence effect in home. very interesting. AAANNDDD you are a very smart and cute girl!. thanks for sharing!!! XD

the ambient noise is eerie, makes me remember the Dartmoor lands.

I never knew that LCD's had indium tin oxide glass. I've finally found a use for all the LCD's I recycled from broken electronics.
