Since the new iPad launched with a revolutionary 2048 x 1536, 3.1 million-pixel display, rumors about the new iPhone's display screen have accelerated -- the most recent indicating that Samsung's OLED screen will replace the traditional LCD display.

The Korea Times recently reported that Samsung has increased the production of the OLED screen for the new iPhone, according to the Christian Post.

Thanks to the increased volume, chances have been raised to ship Samsung's OLEDs for Apple's iPads and even iPhones, an unnamed source told The Korea Times.

Apple is ironically the biggest customer of its prime competitor. The company bought $7.8 billion of components from Samsung, including memory chips and LCDs, in 2011, according to the Korea Times. This year, it will buy around $11 billion of Samsung parts despite the deepening legal battle between the two companies.

Both the Samsung Galaxy S2 and Galaxy Nexus -- the iPhone's prime rivals -- use the OLED display. Apple has been reluctant to use it in the past, claiming the screen had some technical issues, according to the Christian Post.

Other rumors surronding the new iPhone

Display:

The latest iPhone 5 rumors point to a 1280 x70 resolution with a Quantum Dot LED curved glass edge-to-edge display. Since the launch of the new iPad, Apple enthusiasts are convinced the phone will come with a retina display. A bigger 4-inch or 4.6-inch screen is also expected after many iPhone customers have criticized the iPhone screen for being too small.

Processor: 

The iPhone 5 will probably come with an A6 Chip, after the iPad was released with the A5X quad-core processor touted as twice as fast and four times better performing than the Tegra 3 chip. An A6 chip would double the power of the A5 chip that is currently used in the iPhone 4s and the iPad 2. An unnamed source, who claims to have an iPad 3 prototype, sent Boy Genius Report pictures of a diagnostic tool called iBoot, which states a chip model number that appears to be that of the A6 chip.

iOS 6 Software:

Ars Technica has published some analysis that suggests some Apple products are already running on iOS 6 software. The analysis would suggest that Apple is either doing a test run on some of its new products. We might expect the new software at the Worldwide Developers Conference, where the iOS 5 software was revealed last year.

Better Battery

The iPhone 4s's battery life is one of its most criticized features. Apple tried to fix the bug with an iOS 5.0.1 update, and while some users said it had improved their battery life, other complained that the performance wasn't good enough. It is therefore likely that Apple are focusing on overall higher battery life and performance, which is paramount if it keeps introducing battery draining features like Siri.
