Do you remember 720p smartphone displays?
Chances are that the sentence above does not really make sense to you because the first 720p smart phones are just in the process of being released. Only having about a month in the spotlight, these displays are already being kicked to the sideline by Toshiba. Earlier this year, Toshiba promised a 4 inch smartphone that would feature a 367 ppi display. However, they have now upped the ante with a 6.1 inch tablet phone “thingy”.
It is unclear whether or not the device will be a phone or a tablet, but we do know that the 6.1 inch display will have an incredible 2,560 x 1,600 pixels. That translates to 498 pixels per inch (pixel density). In addition, Toshiba says that it will “boast a 1,000:1 contrast ratio, 16.7 million colors, 61 percent coverage of the NTSC color gamut, and viewing angles of 176 degrees both horizontally and vertically.
If you are still not satisfied by what looks to be the most incredible and un-believable smartphone display, Toshiba has added one last feature – 3D capabilities – that do not require glasses. With a display like this one, users can now watch movies in full HD (1080p) and also in 3D without those pesky glasses. The question is, can we do both at the same time?
And just for perspective, look how this upcoming display from Toshiba literally dominates every single display on the market – including the iPhone 4S and Galaxy Nexus. Remember, we are talking about a display with 498 PPI – a huge improvement!
There is no information on when, where, or how this will hit the market, but we are sure that Toshiba has leaked this information to try to keep people from buying into 720p displays when mobile devices with displays better than 1080p are right around the corner. Also, if you’re wondering about the 6.1 inch size, and are thinking what kind of device would that go in, then worry not. Much like Samsung was able to reduce the size of the 1280×720 Super HD AMOLED panel from 5.3 inches in the one used in the Galaxy Note to the 4.65 inch variant for the Galaxy Nexus, so too will Toshiba be able to make this one smaller for use in smartphones! And you know it’s coming to Android first!
Any thoughts? 720p enough to seal the deal for you like on the LG Optimus LTE, or the Galaxy Nexus?

At that resolution, a 1920 x 1080 display would be about 4.42″ diagonal. Makes sense for a phone.
Peope does not distinguish more than 300 ppi, overkill i say! Or at least is a subproduct of the display technology.
“Peope does not distinguish more than 300 ppi”… Your comment is simply ignorant. It is impossible to define any ppi number as having any relevance to what can or can not be seen by the human eye without also specifying the distance between the display device and the eye viewing it. You could replace the number 300 with any other number and your comment would be no more and no less pointless.
A human being, with 20/20 vision, can resolve 1/60th of a degree of arc. If you have a 6.1″ display with a resolution of 2560×1600, each pixel will occupy exactly 1/60th of one degree of arc when that display is 6.9″ away from your eyes. That’s the distance at which you will be able to clearly see each individual pixel. The whole point of using a high resolution display is an attempt to make the individual pixels impossible to discern. A standard distance for near viewing of a phone screen is 13″. At that distance, a 6.1″ display with a resolution of 2560×1600 is almost exactly what is needed to allow two pixels in every 1/60th of a degree of arc.
Or did you think they picked those numbers at random?
I’m honored of all the words to such an ignorant bastard as me. I forgot to add that at 20/30 cm which is the standard distance to look at a paper, or phone in this case, you can not distinguish more than 300 ppi.
One more time, using centimeters: Assuming 20/20 vision, the human eye can resolve anything larger than 1/60th of a degree of arc. Pixels at 300ppi are equal to 1/60th of a degree of arc when they are 29.1 centimeters away. That means that if a 300ppi display is any closer than 29.1cm, you will be able to see the individual pixels. That would be bad. To prevent that, manufacturers use higher pixel densities so that the pixels are too small for your eye to see. That would be good.
It’s only Wednesday. Is there anything else you’d like to be wrong about this week?
i understood the first comment perfectly well you pathetic little know it all- as of course there is going to be a relevant distance= Do you really think someone reading an article such as this one doesnt know this?
Where do you think you are?
His lack of mentioning it just made me surmise he was referring to an average distance.
Your snide, pedantic and downright nasty comment is one of the most illuminating things i have ever read- not about technology or screens or angles of arc but in the truly vile side of human nature, you nasty, stuckup, conceited, smug, unpleasant, pious, vicious, pathetic excuse for a human being.
Please, please kill yourself as your existence on the same planet as me fills me with loathing for my fellow man and shows that even someone with a higher understanding of technology -and hence not an insignificant intellect- such as yourself can be so abhorrently demeaning, deriding and emotionally void –
The fact you use your self perceived (and possibly delusionary) superior knowledge of the subject matter to attempt to belittle a man who made a perfectly good point (and quite a prescient one in a more general sense about overkill in development of such products and incidentally the forces that drive such advancements and their necessity).
makes we want to smash your spoiled little face into a mushy lump and poke your fucking eyes out you heinous little bastard.
I hope your mum gets cancer and you develop hideous boils.
If you want to play at nasty i suggest you learn how to do it properly you pathetic little tinpot, holier than thou bully.
Now go fuck yourself (in the ass with something sharp preferably).
Ya fucking prick.
