For a TFT screen such as the 3.5 or 4.3 inch available in gadgeteer version, what are reliability concerns over long period of time (1 year, 3 years, 5 years+ ) ?
-Does changing the content on the screen really helps ? (like old screen savers)
-Would adjusting the brightness on the screen help (for example control the PWM led driver with an analog out?
-what other concerns I should worry about on about longetivity of TFT screens?
-Any possible way to detect a failed screen remotly (without anyone seeing that the screen is not working)? I though about putting a current sensor, and if the PWM led driver circuit is dead, maybe the total current consumed would drop and I could raise an alarm remotly…
Right now Ihave a TE35 gadgeteer screen mostly opened with the same image for over 6 months, with no apparent problem or deterioration.
But I would like to plan ahead for our product.
