Are you talking physical screen or image that gets painted on the screen?
I'm no tech guru, I'm just a hobby programmer, but the way I understand it from stuff I have read over years, is that the E-Ink method, is to create a shades of grey image by painting ink dots that stay in stasis by a trickle charge. That image is not recreated and is only painted again on some change ... Font related or page change. Because it is a minute charge, that is why the battery lasts so long.
On the other hand, the image painted on an LCD/LED screen is constantly getting recreated, pixel-wise, hence the flickering. To counter the flickering, they use a backlight that alternates with the flickering, giving the visual illusion of no flickering. It is a pulse modulation scenario. The flickering is always there though, and supposedly your brain can detect it at a subconscious level, even if your eyes don't report it to you.
Like many things in this world, they only tell you part of the truth, when they say Flicker Free.
That said, it would definitely be better for your eyes, than not having that backlight. E-Ink however is a lot better still.
It is hard to see them coming up with a better alternative to E-Ink, only a better version of E-Ink that supports color.
In the end, it is all about how the image gets to the screen and is maintained. So in that regard the LCD method will stay the same, if it is still called that.
All of the above, is just my loose understanding of what has been filtered into my brain, and without a doubt, much is missing from my descriptions ... and my memory may even be faulty ... or missing bits at the very least.
