Apple took credit for launching one of the highest resolution screens on smartphones, when it introduced the iPhone 4 with Retina display in June 2010. Since then, other manufacturers have attempted to emulate Apple, and if the latest rumors are true, Samsung Galaxy S4's display will put Apple's Retina Display to shame.

The latest rumors about Samsung's upcoming flagship smartphone of 2013, the Galaxy S4, are beginning to heat up and it seems Samsung is no longer taking a back seat to Apple when it comes to innovation with its mobile offerings. The Samsung Galaxy S3 proved that Samsung could compete with Apple and even surpass the latter, which is known for being the most innovative smartphone maker. That title went to Samsung in 2012 ,with the Samsung Galaxy S3. The Galaxy S3 topped numerous charts and became the highest selling smartphone released in 2012, relegating Apple's iPhone 5 to 2^nd place, a place Apple is very unfamiliar with. That's the price you pay when the competition overtakes you in the innovation race.

A new report claims that Samsung's Galaxy S4 will feature a 4.99-inch 440ppi (pixels per inch) Full HD Super AMOLED display. This screen and resolution will give Samsung bragging rights of delivering the best display ever found on a smartphone.

To achieve this, Samsung is rumored to be developing new pixel layouts for its AMOLED screens and will use hexagonal and diamond shaped layouts compared to the previous square ones it has used in the past. The change is expected to pack more pixels into the display and produce a much sharper screen.

When Apple introduced the iPhone 4 with its revolutionary Retina display, it brought the term ppi (pixels per inch) into the smartphone world. When Steve Jobs unveiled the iPhone 4, he claimed it had virtually no pixels that could be seen by the eye due to its 326ppi. The average eye can't discern anything past 300ppi, so at 326ppi, Apple created something that had never been done. Apple revolutionized the industry by forcing smartphone manufacturers to offer screens that could compete with the iPhone and now its rivals, including Samsung, are looking to surpass Apple's innovations.

It appears that Samsung's Galaxy S4 screen will not only compete with the iPhone Retina display but it will put it to shame by offering a gorgeous, sharp, 440ppi screen. Perhaps that's not innovation but evolution it sure is.
