Question display lcd led ips

[and77man]

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 because not use long periods?

 

[ahsrabrifat]

When powered on after years of storage, the display might initially show sluggish response times or faint ghosting, but this can often recover with regular use.

 

[and77man]

is permanent this problems after many years or decades without use lcd led ips display?

In the gpt chat it says that if I store the ips led lcd display for years or decades without use there will be problems with the backlight, leds and pixels, is this true?

Real-World Evidence

• Old Monitors: People have revived 15-20-year-old LCDs stored in basements, often finding them functional but dimmer or with capacitor issues (e.g., recapped CRT/LCD anecdotes on forums like Reddit’s r/retrotech).
• LED Aging: Studies (e.g., DOE reports on LED reliability) show unpowered LEDs degrade minimally over decades in controlled environments.
• Capacitor Lifespan: Manufacturers rate electrolytic caps at 5,000-10,000 hours at 85°C, but at 25°C, this extends to 20-40 years (Arrhenius equation: lifespan doubles per 10°C drop).

Storage Tips to Minimize Problems

1. Cool & Dry: Store at 15-25°C, <50% relative humidity (use silica gel if possible).
2. Dark: Avoid UV light to protect polarizers and plastics.
3. Flat/No Pressure: Prevent LC misalignment or cracked glass.
4. Sealed: Keep dust and bugs out (e.g., original box or plastic bag).

Conclusion
Storing an IPS LED LCD for years or decades can lead to problems, primarily with the electronics (capacitors) and, to a lesser extent, the LED backlight (dimming). The pixels are unlikely to fail unless damaged. With good storage, it could work after 20-30 years, but after 50+ years, expect repairable issues (e.g., recap) or minor degradation. If you’re planning this, let me know the timeline or conditions—I can refine the prediction!

My Anecdote

LCD quality has improved to become pixel defect free new. If it failed in storage is that a similar mechanism to flash memory storing capacitance charge defects and degrading after so many years depending on quality and environment?

Does the past quality predict future trends?

here varies temperature Brazil my home storage 34-36C humidity 57-67%
my electronics are handhheld consoles R36S and Powkiddy Q80 not use aluminum electrolytic capacitors
i store in cardboard boxes original console

No, long-term storage won’t cause permanent image retention, but liquid crystals might become sluggish. Usually, just powering it on and running it for a while should bring it back to normal. Extreme humidity or heat could be a bigger issue over time.

 

[and77man]

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?

 

[rjenkinsgb]

Unless you have some cooler, lower humidity storage, there is absolutely nothing you can do to affect what is going to happen over time, so all you can do is wait & see what they are like when taken out of storage!

You cannot control it so you may as well accept it & get on with your life.

 

[and77man]

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?

 

[rjenkinsgb]

The key fact is that YOU HAVE NO CONTROL OVER IT - When you get them out to use as some point in the future, you will find out if any have decayed or not.

 

[and77man]

Do the backlight and LEDs of the IPS LED LCD display suffer permanent changes, losing performance due to long-term storage?

Do dead pixels appear?

 

[rjenkinsgb]

These are some of the oldest handheld computers in my collection; the Psion 2 (two-line one) is 39 years old, the Psion 3a is 34 years old and the Psion 5 is 28 years old. All ones I bought new myself.

All still work perfectly, They are stored without batteries but that's all.

There is no ways of knowing how long any individual item from some manufacturer will last - until eventually it fails, at some unknow point. Only then can you find out what caused the failure. It could be five years or a hundred years or more.

Personally, I think this thread is exhausted.

 

[and77man]

How many years were these displays stored without power? liquid crystal and leds no die?

I have portable consoles R36S and Powkiddy Q80 they have LCD LED IPS panel display and I store them in the dark inside boxes unfortunately even using a dehumidifier I can't control humidity 57-68% and temperature 34-36C if I store without power and without use for years the LCD LED IPS display will lose backlight efficiency, loss of power and efficiency of the LEDs, the liquid crystal will generate dead pixels and LCD slowness problems

 

[rjenkinsgb]

How many years were these displays stored without power? liquid crystal and leds no die?

The device ages are in the post & storage times are the majority of that.
The LCDs are still perfect, as shown.

You have had endless answers and just repeat the same question. I'm done.

[Einstein made a comment about doing the same thing over and over again and expecting different results!]

 

[and77man]

you temperature e humidity storage is 25C 50% RH? your display is very good condition

 

[and77man]

During long term storage you mentioned that the liquid crystals of the IPS LED LCD become slow, is this permanent or recoverable?

In long term storage for years, will LCD develop dead and stuck pixels?

Do LEDs and backlights lose brightness and color during long term storage for years?

Will temperatures of 36C and humidity 58-68% cause this?
