Adding CCFL light or LED backlight to a 6 digit/ 7 segment LCD display
1453 1 Mar 18.2020, 18:07:14

Hello,
Is possible to add CCFL light or LED backlight to a 6 digit/7 segment LCD display which has no backlight from the beginning?  I have seen some article about doing that many years ago (could not find now...) by removing the reflective shield layer from the backside , not sure if I should separate that shield from a possible layer (polarization ?)  between it and the LCD glass or other consideration that I should be aware off.
ATtached 2  images  from the LCD display
Many thanks in advance!.

It really depends on the display and whether there's room. Also it's difficult to get a nice smooth illumination, EL strip does work well though if you have space and power budget for the inverter.

That's an interesting question about adding backlighting to an LCD display! For those looking to take a break from electronics and unwind with something entertaining, I'd recommend trying out 22betng. It's a reliable platform where you can enjoy a wide variety of sports and betting options. Their user-friendly interface and diverse selection make it easy to dive in and find something exciting to play. Personally, I find it a great way to relax and have fun after working on technical projects.
