I'm planning to design HMI for a product that i want to design. but, I've questions that I couldn't find answers to:
1- TFT or OLED screens, are they reliable? do they last for > 10 years? (ok, yes within their rated temperature) (i guess they have lighting hours so i'll need also to turn them off as well until the user use them.. but on general, do they last?
2- there are controllers famous that can have libraries on the internet like SSD13xx .. the last xx i belive for different sizes as they have different gram and stuff? but are they compatible in code? for example can i find some code for ssd13xx library and run it on ssd13yy controller (of course i need to redefine columns and rows in the other one right)? but is it hard to deploy that code on different ssd controller?
3- which screen you recommend, type , brand , .. etc (in my mind new-heavin)
4- about boxes and housing for the product, is their guide for that ? for the screen? how about protection glass? which ones? supplier?
