According supply chain sources, the 7th generation iPhone (iPhone 5S maybe?) may come with higher resolution
screen and higher pixel
camera.
The so-called "Retina+"
Display update is thought to be Apple's attempt at keeping up with the higher resolution
1080 screens found on the majority of flagship Android
phones for 2013, displays which the current 4-inch 1136 x 640
screen struggles to keep up with.
Source from close to Apple's supply chain suggest the
new display would have to be an
IGZO panel from Sharp, which can offer high pixel numbers on such a small
screen.
With the higher resolution
display it is also expected that
Apple will boost the rear
camera to a 13 mega-pixel sensor, and also fit a larger battery to the
new iPhone 5S.
