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? i have store handheld consoles
Why ask on the Arduino forum when a simple search for "LCD storage" will immediately return a link to answer all your storage questions?
LCD, LED and IPS displays may experience changes in liquid crystal molecular properties, aging of backlight modules, pixel problems and image retention if not used for a long time. (You can search on Google for specific situations)
In addition, Paul is right, a simple search for "LCD storage" can get the answer you want
is permanent?
Yes.
Is it possible to avoid this without having to turn on the IPS LED display frequently?
only if stored at absolute zero K.
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?
All things are subject to decay and other problems over time. All electrolytic capacitors are capacitors because of chemical activity. After years, they do not work like new. Resistors used to change values over years because they were carbon based. Today's metalized resistors have a really long life time. All solid state devices, transistors and ICs are made using chemical etching with extremely active chemicals. Almost all those chemicals are washed away or neutralized, but exactly 100%. Only enough to get by with. So over years, they will find a way to continuing to etch the silicon and kill the piece.
So your concern about a single component is misplaced. Commercial devices are designed so the useful life of the design is less than the life of a single component. The device in question will become obsolete before a component dies.
my temperaturew home 34-36C humidity 57-67%
I would be much more concerned with stuff growing on the electronics!
??? not i understand
Have you seen green on copper?
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?
Truthfully, manufacturers don't care about how you use or store their devices. Any storage test done will be the problem of whoever uses the item and plans for storing it. Most things only last a few years, anyway. And if a LCD display that stops working is key to your product, then repair or replace the device.
in my conditions 34-36C 58-68% backlight LED fast degrade and loss brightness?
liquid crystal confused altered position in storage? LCD LED IPS
Hi, @aranbafdan88
Do you have a project in mind that needs answers to longevity of components?
