https://wiki.mobileread.com/wiki/Reflective_LCD says the LCD display consumes 20mW. So if you turn on the reader every time you want to read then it is not obvious that this power consumption affects the total reading time so much. Was it 20 hour reading time that was claimed for the Cybook? That is 50mW with a 1000mAh battery. So you get 15h or so with the LCD display. |

Simple but useful!
I would like a clock (as per hack somewhere else on these forums) as standard AND estimated number of pages left in battery!
I know that may sound daft but with a device that does not allow you to carry a spare battery around this has been the only pain for me. 3 times now I have got on the train only to find after a couple of pages it turns off since the battery is too low. Now you may say - just regularly charge it up! But, as we all know by now with mobile batteries being the worst culprits, these lithium-ion have the longest life if you charge fully & then discharge fully before recharging again. When you have no ability to (easily) swap out the battery this becomes even more important (even if it means I take something else to read with me on the occasion it does run out on the road, erm track ) |

It's very efficient with an ARM cpu and a eInk display, than it is with an ARM cpu and an LCD display. Especially if you're a slow reader, or someone who reads over time (like most of the world). The LCD would only benefit those that would breeze through a book a day, or enjoy turning off and powering up their eReader. So, it depends what you're going for. How fast you read or page changes over time. I'm sure most people would rather base their battery's lifetime on page changes than on how long their battery has to live.

HarryT claimed he got 25 hours reading time with his Cybook. So obviously that machine is not for you. The discussion was about machines like the Cybook and if a LCD display would be an alternative for machines with these kind of reading times.

I think there's 2 core audiences. Most would rather have the eInk I believe. Also, as eReaders grow in size, the more power is needed to show an LCD page. That's where eInk will most likely dominate (IE: newspapers display). |

I dont understand the arguments going on here. eInk devices generaly last significantly longer than LCD devices, they are lower power, my SONY easily lasts a month between charges, reading every day. Its easy on the eyes, unlike LCD screens.
I just dont see the point in arguing the case of LCD. |

At the moment, eInk is king. It'll most likely stay that way as eInk grows in innovation. |

If you read a page of text at ~36 seconds, than you'd be equal to reading via eInk (or even more efficient if you read faster). If you read slower than that, then eInk will save you more power in the long run. Last edited by Scythe; 09-09-2008 at 11:26 AM. |

If you are thinking about the number of pages you can read in a certain time period then your eye sight also matters (font size). |

I'm guessing there'll be a new model with the new Epson controller and possibly touch screen.

I'm hoping for a larger screen version, because I'm happy with my 505 for 'regular' books but wouldn't mind a larger version for pdfs. Don't really need wifi (or wireless buying), though if I had it I'd use it to transfer books, articles, etc., onto it.
Anyone else appalled at some of the lines on that 'postcard' image from Sony announcing the event? I read some of them... kinda grim for an ad! |

Also, the 99.5% statistic is both incomplete and incorrect. It is incorrect in that it assumes that the average reader takes 200 times as long to read a page as the device takes to change it. If we consider a nominal .1 second runtime, then your statistic assumes that the screen will remain unchanged for 19.9 seconds. I can read the Kindle page in less than 3 seconds. I bet most people who own an ebook reader are almost as fast (if not faster) than me. It is also incomplete in that it assumes a linear reading pattern that mainly applies to fiction. True, this is the most common way that an ebook reader is used; but it's not the only way nor is it even in the majority. There are numerous other things you could do with a book that would involve flipping the page repeatedly. This would negate any benefit of an Eink screen, and heighten its deficiency: very slow screen refresh. I will agree, though, that the Eink screen is a much nicer experience. But the screen refresh is too slow. If the next gen screen come out with a .01s refresh, I might get one. I would also agree that there are some situations where an Eink screen is better than LCD. But in most situations it is not. |
