The 4th generation iPhone will not possess a 960x640 pixel display. Clearly this is a joke taken out of context by the dreamers. A 960 x 640 pixel display would be ridiculously resolute, even on a larger ~4 inch screen. The nexus one has an 854 x 480 AMOLED display which is about as good as you can get for mass manufacture right now.
My (educated) guess is that apple have had a big dilemma about the screen, and it could turn out to be one of the biggest surprises on the 4th gen device.
The problem is the apps are very much focused on the original 480x320 standard, and apps are the iphones strength in an increasingly competitive market. So they have 3 options;
- 1: Stick with the current resolution (although may still improve it in other ways, e.g. going to AMOLED).
- 2: Increase the resolution but allow old apps to run at their intended 480 x 320 - making them potentially very small.
- 3: Or they could possibly include a GPU based scale-up feature for old apps like the iPad does. HOWEVER this is quite easy for the ipad since it is an easy 1:4 ratio. But the iPhone just wont be able to support a 960 x 640 pixel display, so any scale up is going to have to be some wierd ratio, which is going to be very difficult to achieve on the hardware, with glitches.
