Sharp had some impressive looking reflective displays last June, both monochrome and color. Sadly we have not yet seen these come to market in the form of an ereader.

Well... I have a Sony PRS-505, PRS-300 and an Aluratech Libre. All are quite legible but I prefer the e-ink to the lcd.

The lcd suffers from the problems all lcd displays have. To get maximum contrast I have to view the screen at an angle. If I look at it straight on, the contrast is no better than e-ink.

The lcd has a slight greenish-yellow cast to it in contrast to the neutral very light gray of e-ink.

Battery life is longer for e-ink but that just means that I have to charge the Libre more often.

LCD displays update faster but e-ink isn't really any slower than I turn the page in a book so I don't see that as an issue.

I have no issue with reading on either an lcd of any type or e-ink. I spend up to 12 hours a day with a computer (22-24" screen) with no problems. All that is required is to set the contrast and brightness correctly. And the correct strength of reading glasses for the conditions.

Resolution is very important (in terms of pixels per unit length). The 5" lcd has about the same resolution as the 6" e-ink. The 5" e-ink display is much better and appears sharper.

That said, I prefer e-ink for reading, colour would be nice.

There are other factors as well. The "fit and finish" of the Sony readers is far better than the Libre. The Libre feels cheap and shoddy. I expect the poorly designed cover for the memory and usb connections to break and fall off no matter how careful I am.

If (when) I get a new reader, the display is only a small part of the criteria I will use to choose with. But my preference, all esle being equal, would be for e-ink.

Note: LCD display do NOT have a refresh rate. The refresh rate only refers to the number of times an electron beam draws the screen on a CRT. This parameter has no meaning for the lcd display.

cheers

LCDs are indeed actively refreshed/redrawn. To claim otherwise is silly semantics.

Yes they are but this has nothing to do with the refresh rate that is set in the video driver. It is not silly semantics.

If you decrease the refresh rate with a CRT, you will start to notice a distinct flicker on the screen, first in your peripheral vision (most sensitive to movement) and then in your central vision. This is a physical change in the nature of the display.

With an LCD the intervals between screen updates will lengthen as the refresh rate drops but there will be no screen flicker as the result of the drop in refresh rate. The screen will look the same.

Since the display has to convert the vga signal to whatever internal format the display uses, there is probably a maximum frame rate that the display can handle. Exceeding this rate may result in missing information but it will not change the naure of the display and certainly not introduce flickering like reducing the refresh rate on a CRT.

If someone has trouble reading lcd dispalys, the refresh rate has nothing to do with it.
