Lifespan or longevity: One of the notable reason why in-plane switching LCD technology has been regarded as more superior than AMOLED display technology is lifespan. Between the two display technologies, AMOLED panels are more prone to screen burn-ins and overall color degradation.
The AMOLED panels used in high-end smartphones can last for less than two years before obvious signs of degradation appear. Note that in an AMOLED display technology, blues and whites fade faster than reds and greens. Over time, reduced brightness, color shifts, and burn-ins become very noticeable.
While IPS panels are also susceptible to dead pixels, their lifespan is much longer than AMOLED panels. A good IPS panel can last from 8 to 10 years without showing noticeable signs of degradation.
The organic materials found in an AMOLED panel are also susceptible to water damage unlike the inorganic crystalline found in IPS panel. Submerging an AMOLED panel in water will immediately result in noticeable damages as represented by screen burn-ins or dead pixels.
