    I actually made it a negative display. I feared that the display wouldn't get enough sunlight but that isn't the case. I also feared the backlight wouldn't function but it functions normally through the glow strip. I would imagine that with a positive display the glow might be even brighter. Someone should give it a shot I will post progress pics later.

    I was about to ask whether the backlight's still functional after the mod, but you clear that up. Can you provide a pic with the backlight on along with the glow? Thanks!

    Very cool mod, by the way!

    Thanks for the clarification. So, UV gets through the negative display. Good to know. Does the EL backlight emit enough UV to power up the glow tape? Guessing it does not, but, ehh, whatever. A blast with a 150 lumen LED light would charge it up, no problem.

    Might look good on a Dw-5600 bb-1. It's already a negative display.

    I wonder if it would work on a mirrored display? They are positive, but when backlit, only the numbers are illuminated.

    It would be great to see a step by step pics.

    Unfortunately the backlight doesnt it enough UV. Normally sunlight or flashlights get the glow going. I'm going to mess with a dummy Casio watch with a positive display and see what results I can get from that.

    Thanks! That proved the backlight's pretty much redundant with the glow material! The only thing is how long the glow will last before you have to recharge it with a flashlight, but that's easy to do.

    The concept of putting glow material behind digital LCD is not new, in fact as far back as the 70's. Here's member ChromeFreeDisco's post with a video of his Fairchild Tritium LCD watch. But somehow the concept was not widespread commercially, nor did other watchmakers (as far as I searched) use just regular analog watch lume for the same purpose like you did. I wonder why? It's so simple! Instead the originally power hungry EL panel was such a big deal when it was first released in 1992 by Timex and then 1995 by Casio.

    Wow that is awesome! I wonder why no one has made an attempt to make this work. I bet that with the right research and materials the results would be even better. So, I modified a dummy Casio watch I have with a positive display, and I see that the positive display let's in way more light. The visibility is way better in the dark and improves more as your eyes adjust to low light.Name:  IMG_20170127_133159.jpg
