Question LCD LED IPS Display

[samusaran88]

I have some consoles that I store, R36S and Powkiddy Q80, and they have an IPS LCD LED panel display. I have questions: if I store these devices for a long time (years or decades) without using them, do the LEDs and backlight on the panel weaken and lose performance even without use? Do the liquid crystals change and generate dead pixels and other problems on the LCD?

Here in my region, the temperature varies from 34 to 36C, with humidity ranging from 58 to 68%.

I am no expert, but I imagine screen backlighting (diodes) degrade over time, even if not in use and stored away, just due to age.
I'd store in the dryest place possible.

Not too dry, static electricity and all...

I'd go with indoors closets spaces verses outdoors metal sheds, etc.

Anywhere with decent climate control lol. I would probably do some calculations to figure out how much silica gel would be required to regulate the humidity in a storage space to about 35-45%.

in longtime storage leds and backlight loss efficience and brightness?

What is the good temperature range for long-term storage of TFT LCD IPS LED backlight displays? Do manufacturers have a range or does it vary greatly between manufacturers? And what is the maximum humidity without presenting risks?

I do not know the models and manufacturers of the R36S and Powkiddy Q80 displays? this consoles uses 3.5" IPS

Have you ever seen the LCD slow down and become complacent after years of storage? Has the problem been resolved or is it permanent on the display?

Unfortunately, I've experienced that very thing.

I wouldn't worry much about the LCD and the LED backlight. It's other components that degrade when they are not used. Is there a battery in there? Maybe a data retention button cell? Electrolytic or tantalum capacitors? I don't know these consoles, but generally speaking cheap consumer electronics are not always built to last.....

i removed battery, no electrolytic capacitors some smd capacitors, led backlight loss brightness in storage? lcd degrade?

I have an LCD monitor that is almost 24 years old that I haven't used for over15 years which still works well, and another one (NEC PA301W) that's 15. I don't think LCDs degrade. SMD capacitors can be tantalums, unfortunately I don't know how to identify them from looking at them.
