Re: Electroluminesence
I recall an electroluminescent panel was used on the Telefunken '709' (?) series of CTV to illuminate the selected channel number. Tony

Re: Electroluminesence
My Panasonic bedside stereo had an electroluminescent backlight, but that no longer lights up anymore. Not sure whether it's the panel that has died or the inverter.
EL panels were very popular until recently, but LEDs -- which can be used directly from low voltages -- seem to have taken over most of their applications now.

Re: Electroluminesence
Agree, LEDs have largely taken over for flat or curved panels.
There must be a lot of vintage or soon to be vintage equipment around that has dead or dying EL panels in it. Authentic repair or restoration may become impossible. A 70 year old valve radio is arguably easier to restore than a 20 year old (and soon to be vintage) device with EL panels. One of the few remaining applications is the electroluminescent wire. |

The spacecrafts were even lit by EL panels Fran Blanche has a series of videos about the subject on Youtube.

Re: Electroluminesence
I'm sure suitable OLED replacements can be made for older EL panels, as they use quite similar technology.
