Question LCD LED IPS display

[adryman]

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 little handheld consoles with display lcd led ips

Liquid crystals can settle or become less responsive if not used for a long time. When powered on after years of storage, the display might initially show slow response times or uneven colors. Usually, this can be fixed by running the display for a few hours to "wake up" the liquid crystals. The LED backlight may degrade slightly over time, especially if stored in humid or extreme temperature conditions. This can lead to uneven brightness or color shifting. Running the display for a few minutes every few months can help keep the liquid crystals active. Use a protective case to prevent dust and physical damage.

the slow response time of an IPS LED LCD (liquid crystals) that has been stored unused for many years is a temporary or permanent defect? During long-term storage of the device LCD generates dead and stuck pixels and the LEDs and backlight of a 3.5" display lose brightness and change colors. Does this occur at any storage temperature or at a certain temperature?
It is difficult to control here because I live in the northeast region of Brazil, temperatures above 30C here in my house vary from 34-36C humidity 58-68%

I have two portable consoles R36S and Powkiddy Q80


Is it 100% necessary to energize the display frequently? If this is not done, are these permanent problems or can they be stored indefinitely?

The problem is usually temporary, but sometimes it can be permanent. If you want to store LCDs for an indefinite time, you should Store them in a cool, dry place with humidity control. If possible, store them in a sealed bag with desiccants to absorb moisture. You live in Brazil, so store the consoles in a cooler environment if possible.

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?

Some datasheets mention storage temperature. If they do, you'd better maintain that temperature. Here are some articles that you may find helpful.

When devices are designed for use outdoors, there are immediately several challenges to overcome and, for us, one of the most important is getting the balance right when it comes to brightness. But why? Surely, to counteract the effect of strong sunlight we simply use a TFT display with high...

I had some bad experiences with the generic 16x2 LCD. After being not used for a long time, they refused to show any texts. I simply had to toss them out and buy new ones.

Wide Temperature Range, Super Wide Temperature Range, Standard Temperature Range Which one of them Storage Temperature specification is most similar to my case of R36S and Powkiddy Q80? TFT LCD IPS LED 3.5"? not mentione humidity range

In your case, the generic 16x2 LCD display had a problem with the LCD due to storage temperature, humidity or display quality? Was it a new display or old technology?
