First i would say thay i didn't make displays by myself, I found a company, making displays for different purposes in Minsk (Belarus)
It took approx 9 months.
For the first I found all technical data about necessary display. It is old type of displays with thick glasses, the only back contact (static not dinamic mode). There are 4 digits and dots. First digit has only 3 segments for 1 and 2. I had made quality pics of existing LCD's and then had drawn them in curves.
Here there are ready drawings of both layers
I started in april, to the end of may all data was at the factory. There were produced 4!!! different samples till the moment we've eliminated all mistakes.
There were to many small mistakes, so new display didn't seem look like. On the pic blinking dots are still closer to each other.
The last sample was perfect. So to the mid of october the production had started. And to the mid of december ready displays had come to me.
I shaped ready LCD's, made angled cuttings for visual identity. Then replaced old displays with defects on new ones.
We had to change construction of displays.
1. I had to change a bit thickness of glasses for better stability (thick second layer not good for temperature changes, becides gives too big shade of digits)
2. In old displays both layers are connected with small metal pieces, in new ones - special glue
3. Had to replace polaroid position on 45 degrees (too expensive to use old direction of liquid crystals).
4. Had to replace aluminium powder painting of lower polaroid film for mirrored film used nowdays, but will try to use silwer painting for more vintage view.
Anyway I'm happy with this result, ready for making new displays :)
