Toshiba to demo a 720x1280 pixels 4
Not long ago we thought Toshiba was a prime candidate for the screen on the next iPhone, or the one after. Cupertino was even rumored to invest in a screen factory together with Toshiba.

After all, the Japanese announced that at the SID expo this week the company will showcase one of its Low Temperature Poly-Silicon (LTPS) LCD displays, 4” in size and, get this, with 720x1280 pixels of resolution.

The high-resolution screen sounds like a perfect candidate to go into high-end smartphones, since, besides the insane pixel count, it sports contrast ratio of 1500:1 (the iPhone 4's screen has been measured up to 1117:1), 92% color gamut (the iPhone 4 covers 64%) and viewing angles up to 176 degrees.

However, the last rumor is that the factory plans with Toshiba were scrapped, and Apple is siding with Sharp for the production of the iPhone 6's display, which, coincidentally, also has an LTPS display production technology that allows for greater than 300ppi density, which is the threshold for a Retina Display moniker.

Nevertheless, Toshiba's screen is a remarkable achievement and should give a boost to the competition, all in our favor as customers.

sorry for the rain on the party but... why do we need a higher density that the one the human EYE can see? I mean "retina display" should be the top a company should go to improve sharpness, companies should be working on better power management or other stuff....

agreed... and idk why this is so "breakthrough" when it is the same ppi as the retina display... it is just slightly bigger...

a wise guy told said once when asked why his company was not interested on getting a res above 400ppi to beat apples and his answer was plain simple:

''Is tis going to really benefit the customer having something they cant appreciate with naked scenes, not so long ago someone invented the dvd audio with a quality thats so good the human ear cant perceive any defects on it, yet the protect failed because the files where big and the proses was more costly, and the real benefit? none same things could apply to screens apple did a great job by not only making the Highness res on a smartphone but setting a limit, a line no one should try to cross above because there is nothing to it. better work on other tings like battery management and overall life of the screen''

I couldn't agree any better

I have searched and searched for a reason why we don have it just to cut bragging rights, all I found is that there are solutions (something related with copyright) but companies don't feel like using them because they are focusing on other stuff
