Default Anybody tried this method for evenly backlighting panels?

So, just found this while doing some research. Going to try it out later this month when I get the shop up and fully running.

Has anyone else tried this? Basically, etch a 1mm grid into a clear sheet, top with thin white, top with legend plate. Edgelight the grid sheet with LED strip.

Not sure if electroluminescent sheets would work for you. These are kind of expensive but they do have the Chinese copies that sell for less than $10.00. They run on 12VDC. I think they can be hole punched and cut to match the panel in question. Not sure if this would be easier though. Also durability in how long they last.

There are several problems with EL lighting that have been covered over at VP.
Noise from the transformer.
Burning out
and correctly cutting and sealing them.
Surface mounted leds are one of the more popular methods of backlighting panels.
But using specific material or this type of etching the panel has been mentioned over at VP
What success or failure they have had I can't say I no longer visit that site.

Thanks for the comments Deadman. I don't go over there much anymore myself. I've wanted to dabble in SMD LEDs...do you have any suggestions as to your preferred part numbers for green, red, amber and white?

No I am very lucky to have all real panels in the cockpit.

ive messed with this before , i build on the cheap and by that i mean i go to the garbage dump and find old lcd monitors to take the back light panel out of them which is normal 3 to 5mm plexiglass with this same pattern. then they very thin Fresnel lenses and some diffusing sheets to evenly spread the light.
