IBM PC110 screen conservation -?

Hello to everybody! This Saturday I received a true masterpiece for my collection of handhelds - IBM PalmTop PC110 in almost mint condition, including the screen.

The problem of PC 110 is that their Citizen STN screens are of very poor quality, which leads to screen degradation after some years (random pics from Google):





As I understand, this happens because of one of the layers inside the screen comes off and starts to shrivel.
This time 99% of all PC110 for sale have these screen problems, in a varying degree. Other example: https://page.auctions.yahoo.co.jp/jp/auction/u313917324


My screen is in great condition, although when displaying black color, there are some very little signs of non-ideal black, but this is usual for all STN matrix.
I wonder how to save it for posterities?
How to store the device so that the screen does not dry out?
Maybe it should be stored upside down?

In one of the forums I read the opinion that this screen degradation happens in Japan only because of their humid salty air and climate. In other countries there`s no risk. But I don`t know.

Maybe someone here has some experience with these funny little notebooks and has something to say?

Thanks!

Sounds like you need to vacuum seal it and then store it in a flight case?

As I recall, when I visited Russia a few years ago, the climate is quite dry and cold. (obvious, but it was. )
Japan is indeed true that the humidity gets very high. Especially during the summer times.

After living in Japan for all my life I can tell you that screens, even though it is not STN, degrade.
Especially it gets yellowish on old LCDs. But that's normal.

I'm not really sure if it is the humidity that does this in Japan. Maybe it's the material's degradation over time?
There are lots of pristine condition old laptops up for sale in Japan, and I get amazed by that..

Anyways, congratulations on getting a PC110. I think it was called "Ultraman PC". For those who don't know Ultraman, it's explained here in Wikipedia: https://en.wikipedia.org/wiki/Ultra_Series

If humidity is the issue, I suggest getting airtight storage boxes, lining the bottom with silica gel packs, and storing the laptop in there!

Silica gel is a buffering material, it won't help to just put it there, you need to dry it before packaging for it to make sense.

Appreciate your sense of humor

Thanks to everybody for responses. In one of the American enthusiast forums I read that not humidity, but direct sunlight and heat is the issue.

Actually the device is stored in a cupboard in special case. Let`s see, what will happen next.
