Toshiba Introduces New 6.1-Inch Display at 498 PPI

Apple has long touted the crisp resolution of its "Retina" display that debuted in the iPhone 4 with a resolution of 326 ppi (pixels per inch), a display that has since made its way to the iPod touch and now the iPhone 4S. The Retina display concept is also said to be set to make its way into the iPad 3 next year, with Apple preparing to quadruple the number of pixels to offer a resolution of 2048 x 1536 on the device's 9.7-inch screen.


Magnified comparison of Toshiba's new 498 ppi display with lower-resolution displays

Toshiba is now pushing the idea even further, today introducing a new 6.1-inch display offering a resolution of 2560 x 1600, coming in at 498 ppi.
This newly-developed world-class, high-definition LCD panel is based on our processing techniques for forming fine-pitch and high-performance, low-temperature poly-silicon (LTPS) thin-film transistors (TFT) on glass substrates, and other precise fabrication techniques which have been cultivated over the years. This direct-view LCD panel achieves high-definition images with photographic quality, and although the images are displayed in 2D format, they impart a sense of depth and realism.
Apple obviously does not currently offer a mobile product in the range of 6.1 inches and other considerations such as ensuring a smooth transition from lower-resolution displays would likely preclude the company from utilizing this exact display, but it is clear that the technology is advancing rapidly to enable ever higher display quality. As mobile devices continue to see increased graphics capabilities and costs fall into line with existing technologies, such ultra high resolution displays are likely to see significant adoption.

if the human retina can't see more than +-300 pixels per inch, why put 600 on 1 inch? You would think that the difference wouldn't matter. I would think that it's more important to make bigger retina display's (retina iMac, iPad?)?

What's the point of a display that's significantly higher than 300dpi? (Yes - I realize the iPhone 4 is 324ish). You're eye isn't going to notice the difference between an image that's 300dpi or one that has higher pixel density. Unless you're holding it right up to your eyeball...

Don't get me wrong - I think this is great. I just am having trouble figuring out any practical applications for this sort of pixel depth. Would there be any tangible benefit to the increased cost?

I do dream of the day when 30in. monitors that are capable of 300ppi are affordable...

That would be a nice PPI for a head mounted device.

Wow, that is crazy. I thought the retina display was good enough haha...

Even print design work is only 300.


There was a lot of debate about this when iPhone 4 first introduced Retina, but when laser printers made the jump from 300DPI to 600DPI, the printed text looked notably better, even if one's eye can't really detect individual dots at 600DPI....

So, a larger screen iPhone with Retina display is possible then, correct?

Keep in mind the term "Retina Display" is Apple marketing speak. I am guessing they will be fairly fluid with the definition, and continue using it for the high-res iPad, which after pixel doubling will not reach 324ppi.

From what I understood 500ppi is about as much as the human eye can discern, so it makes sense to get the technology to this point. Even if we rarely have our devices less that 12" from our faces.

I think the 300dpi theory is for AVERAGE human eyes, so 50% people are able to see more detailed stuffs :p


Do you know what means average?

Oh God, first a 4" android phone.. then 4.5".. now the Nexus with its 4.65" screen.. now this 6.1"? When will it stop?!

I doubt that it's intended for a phone. 6" happens to be the average size for e-readers though.
