Who doesn’t love the soft glow of electroluminescence? This EL panel is a flexible plastic sheet which contains a phosphor layer and lights up with a neon-like glow when the proper voltage is applied. It’s a lot like the ever-popular EL wire except, well, it’s a panel. Panels are particularly well suited for backlighting LCDs as well as illuminated signage.
These can be driven with any of the EL inverters and sequencers that we carry and come in a variety of bright colors (check below for other colors). This particular panel is 10cm square and illuminates white. It is attached to a 20cm cable which is terminated with a JST PH connector.
Note: These panels can be cut to any shape! Regular scissors work fine to cut this EL panel but after you’ve cut the panel you should seal the exposed edges with some tape or epoxy to avoid shorting the panel or shocking yourself.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I purchased this lovely little EL panel to add a backlight to my RC aircraft transmitter’s display. I worked like a charm, minus having to deal with interference generated across the 72mhz spectrum. Not too much of an issue though, as I just shielded as much of the area as I could. That seemed to silence most of the noise.
The only thing I dislike about it is that it only has one set of inputs, so the cuttings are pretty much wasted.
After constructing a high voltage oscillator of the appropriate frequency I cut the device to shape. It was necessary to make a 90deg angle bend in the connector to conform to the surface of the part I had to fit it to. A slight short rapidly caused the entire conductive surface near the connector to arc and vaporize. I was never able to establish a reasonable way to reattach the electrodes to the device so I wound up not using either of them.
Surprised the connector didn’t fit any of my el wire inverter connectors but thankfully I had extras lying around so a few slices later… bob’s your uncle!
It was my first el panel experiment. It will take some very expensive practice to get precise shapes, so it will be cheaper to mask it instead. White panel looks good..
I’ve had no problem with the actual use of these panels– they’re bright, cut easily, and work perfectly in my projects. But the strain relief tore out in the first one I ordered, while placed on the curve of a prop. I’ve mounted the second one differently to keep it flatter, but am still concerned anything less than completely flat will make it fail eventually
