Question storage lcd

If I keep a portable electronic device that uses an IPS LED LCD display unused for many years, will the display have problems? I protect it from light and extreme temperatures.
 
display IPS LED LCD is not energized frequently and is stored for many years without use, the liquid crystals will go to sleep and will not respond correctly. Will it generate problems with the pixels and permanent image retention bexcause many years not use?

i read in chatgpt
 
In long-term storage years without use of the IPS LED LCD panel, the liquid crystals suffer from dead pixel, evaporation or degradation of the liquid crystal materials, Failure of the TFT transistors?
 
If you store an any IPS LED LCD panel without using it for a long time (many years), will the pixels develop dead and stuck pixels? Can liquid crystals settle over time, leading to slow response times or "stuckness", where they may not change state correctly when turned on after years of inactivity? Do LEDs and backlights die or lose efficiency?
 
yes but no, sometimes they will but not. And if you store an any IPS LED LCD panel for many moons they may get wokeness instead of stuckness.

it'll be fine. just store them.

I can't say for really long time, like decades or anything, but I can say at work we've had LCDs that we've stored for over a year and they've been fine when they were taken out and deployed.
 
My devices are handheld consoles Powkiddy Q80 and R36S

My maximum long-term storage temperature is 36C with humidity 58-68%, do LEDs have a maximum temperature they can withstand before they start to degrade and lose efficiency and brightness? Is the backlight associated with LED degradation?

Does LCD (liquid crystal) have a maximum storage temperature it can withstand before it degrades? LCD is organic, so it degrades quickly?
 
I've stored LCD monitors in a vented attic in Arkansas for years at a time and they still work.
 
In long time storage LEDS and backlight loss efficiency and brightness? in my conditions 34-36C 58-68%

Yes, over long-term storage, LEDs and backlights can lose efficiency and brightness due to several factors, even in your conditions of 34-36°C and 58-68% humidity. Here’s what happens:

1. Thermal Aging

  • Heat accelerates degradation of LED phosphors and encapsulant materials. Even in storage, the materials inside LEDs slowly degrade.
  • Your temperature (34-36°C) is warm but not extreme. However, prolonged exposure over years can still lead to gradual efficiency loss.

2. Humidity Effects

  • At 58-68% relative humidity, moisture can slowly penetrate LED packages, leading to corrosion in internal connections or degradation of the phosphor coating.
  • If the humidity fluctuates often, condensation risk increases, which can damage electronics.

3. Electrolytic Capacitor Degradation (for LED Drivers)

  • If stored with power off for years, electrolytic capacitors in LED drivers can dry out, affecting startup performance when the device is used again.

4. Phosphor and Plastic Aging

  • In backlit displays (like LCD panels), the LED phosphor layers and diffuser plastics can yellow over time, reducing brightness and altering color temperature.

How to Minimize Long-Term Storage Degradation

Store in a cooler place (~25°C if possible) – Heat is the biggest factor.
Use airtight packaging with desiccants – Helps prevent humidity-related damage.
Power up occasionally (~every 6 months) – Helps keep capacitors in good shape.
Avoid direct sunlight exposure – UV can degrade plastic components.
If the storage is for a few years, the brightness loss will be minor. But for 5-10+ years, degradation could become noticeable, especially in backlights.


Here is chatgpt's answer to you.
 
You aren't listening to anyone's advice either so not sure what you are wanting. Ask the manufacturer of the lcd for what their storage conditions are or look at the manual.
 
Storage is going to be like everything, a bell curve. If you store at manufacturer's recommendations most likely you will be fine. As you increase in temp and moisture you start to move outside that safe area, you might still be fine but you are aging the product. Nothing will last forever without some level of degradation. How much it is, you won't get that info as that test data is not public knowledge that any of the mfg's will share.

above 60% RH you are starting to push things, but as said maybe it won't even be a noticeable effect. cheap vacuum sealer and desiccant packs to toss in there and store them that way if these aren't to be used and you care (which seems so).
 
I was advised not to use chatgt because it is not reliable.
its not, and hes making a point. youve ignored everything everyone has told you. so either go listen to chatgpt, talk to the oem, or take the advise provided.
 
I don't know the model and manufacturer of the R36S panel 4 display and the Powkiddy Q80 display. I searched a lot and couldn't find it.

I prefer answers from knowledgeable people on the forums and not chatgpt
 
You could store them in mylar bags if moisture if a concern. My attic can be 99% rh sometimes and it didn't seem to matter. They sit on the wood floor and besides dusting never have required maintenance. I wouldn't store guns like I store these monitors but these are cheap monitors that we use to surge for things sometimes and they just work.
 
All this is over a chinese 30 dollar handheld? More likely the rechargeable battery will be crap long before the display goes bad
 
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?
