So bottom line, will there be a 300dpi gray scale screen or not?
Btw, I don't understand why current eink devices would do antialias when the pixel structure isn't visible. Last edited by Barty; 01-20-2012 at 10:28 PM. |

bottom line is that Eink can build 300 dpi display film now. they are working with Epson to create the display controller chip to drive the 300 dpi displays. whether any oem will pony up to drop that display into a product when ready is completely up in the air.

As for the pixel structure, I can see that with my bare eyes on my 6" Pearl Odyssey screen at 167 ppi. On my 200 ppi PRS-300 I almost cannot. That is of course at a very close distance unsuitable for reading. If you have uniform black or white areas on the screen you won't be able to see gaps in between individual pixels with your bare eye. I am not even sure you would see distinguishable gaps if you use some magnifyer that allows you to see individual ink particles. One pixel of eInk consists of many particles. Now the color version (Triton) is a different story altogether, as that example of Jetbook that is shown only has about 100 ppi for color pixels. That should be noticeable by a lot more people. Edit: plus what Dulin's Books said. Your computer monitor would be useless w/o you graphics card. Last edited by DuckieTigger; 01-21-2012 at 12:17 AM. |

Also interesting Kindle does appear to be using AA algorithms when displaying text. That might or might not explain why other devices are less or more fuzzy than Kindles even with the exact same screen. (Hint: different AA algorithms have different results) |

yes , exactly. its why answering this question https://www.mobileread.com/forums/sho...d.php?t=166215 is not as simple as it might seem. they are the same display material but the actual software that is used to drive the display and the various pieces of software that are used to actually display the font, the font itself etc etc.
even the same device on two different firmwares can be more or less fuzzy |

Yeah, that is the exact same screen that is underneath the Jetbook color, before the color filter got added, reducing the usable resolution to: 800x600, 100 dpi because each color pixel consists of 4 b/w pixel.
