I don't know if this is know by y'all but I had problems with the OLED display that I used in my home baked Bathroom Fan Controller: it burned up/deteriorated.

The problem was that I didn't knew that OLED displays have a limited life span. 
This will differ with the type and brand of-course.  But the Chinese ones I had in my drawer DO have a life span of 1000 hours, that is only 41 days of 24/7 use!

I 'solved' the problem by temporarily adding a PIR sensor which turn on the display only when I'm around.  But I plan to use a TFT display in a new version.

The 1.8" TFT display in my Gorgy Clock is still great after 8 years 24/7 use!
I never expected that!  And I like to use color displays anyway so exit OLED Wink

BTW: the Real time clock module in it (Chronodot v2 / DS3231) has proven as accurate as advertised: only 30 seconds a year deviation...  Like

Several years ago I did some research with oled, made them by myself and I was happy when it worked several hours (if it worked).
So I think an lot of happened here within the last years. Also there are devices running 100 thousands of hours already. And since you light up the pixels the readability is also much better. Depending on the usage oled displays have some advantages.

I installed a brand new oled display today and will report in 40 days how things are going.

Hello,

I'm using OLED display in my AQM-II device - continuously for more than 2 years. And without any problems...

Hi edr1924,

You have a lot of nice projects on your page, have to say that I'm impressed with your skill for building some of them, the end result is very good, as we can see by the clock.

Regarding those small OLED displays, my experience is little representative, in use 24/7 I only have two, working for near two years, one of them is fully readable like new, the other, while quite readable, after a few months of use, developed what seems like pixels with low bright.

I'm really drawn (no pun intended Smile) to the epaper displays. The high contrast really does it for my aging eyes.

Thank you all for your feedback and thanks Caneira... The DCF clock was my first project, took me a year to build but it was a nice exercise.

I must have had some BAD oled displays...  I'm happy to read here that they DO have a long lifespan...
Maybe I will try to buy from Adafruit for example?

But beside that, I prefer to use color TFT displays... I'm remodeling my Fan controller now with such a display and wifi connection to display the weather forecast etc.

Wow, I love your AQM device!  I love it to see how creative other builders are!

Amazing, I read on a website that they only last for 1000 hours but that was obviously very inaccurate!
