E-ink（screen）monitor has been released for 2 years, and I'm just curious to know how long I can expect a E-ink monitor（screen） to keep working for if it's treated well?
Unfortunately, I've not seen any reports of lifetime of e-ink screen monitor.......
So I decide to estimate the average life of E-ink monitor（screen）.
That's the principle behind E-ink screen.
White and black microbeads have been realigned under the action of the electric field, and then the picture will change.That's an act of refresh.
Over too many times of refresh, White and black microbeads will lose their magnetism and then E-ink screen will fail.
Eink.com says “Over 90% of E Ink screen displays will last more than 10 years with typical usage(as E-Book Reader)”.
Most people believe that their kindle screen can last more than 15 years, even 20 years.
How many times you can refresh your 6inch kindle in 20 years??
1. A 6inch kindle, 250 words /frame; reading speed: 250 WPM; every 1 minute, refresh 1 time.
2. You read kindle books 2hrs/day; refresh 120 times /day; refresh 876000 times /20 years
3. You use your e-ink monitor（screen）for web surfing, 6hrs/day; Every 15 sec, Scroll (mouse) wheel 1 time, e-ink monitor refresh 1 time; refresh 1440 times /day.
4. Hypothesis : e-ink monitor（screen）can also refresh 876000 times（like a kindle） in its lifetime.
5. e-ink monitor（screen）can last 608.33 days for web surfing, and Lifespan of the E-ink monitor（screen）is about 1.66years.
All in all, I estimate that Lifespan of the E-ink monitor（screen）is about 1.66years(surfing web: 6hrs/day).
Am I Wrong?
